To embodiments of the invention be made with reference now, one or more examples of embodiment byShown by accompanying drawing.Embodiment is provided by the elaboration of the present invention, and is not intended as to thisThe limitation of invention.For example, can as the feature shown or described by the part of one embodimentYet a further embodiment can be used to generate in another embodiment.It is contemplated thatThese and other modifications and variations including belonging to scope and spirit of the present invention.
Fig. 1 shows air fryer 100 according to the first embodiment of the invention.The air is friedPot 100 includes：Container 101；Heater positioned at the top of container 101 (is not shown, led toIt is frequently located in the lid of covering container 101)；Food supporting member 102 in container 101；Air-stream generating device (not shown), such as fan.Air-stream generating device is generally also disposed inSo as to form air-flow by the air of heater heating above container.The heated air-flow can be withThe contained foods surface of food supporting member 102 is flowed through to heat food.Food supporting member102 generally have ventilative bottom 1021 in order to which air-flow can reach food supporting member 102On the bottom of food supported in order to heating food in the whole surface of food.In Fig. 1In shown embodiment, the food supporting member 102 is grid disk, and food can be placed directlyCooked on the grid disk.The food supporting member 102 can also be with ventilative bottomWith the basket (see Fig. 3) of ventilative side wall, or there is ventilative bottom and air-locked side wallBasin.
Air fryer 100 also includes being located in container 101 and positioned at the lower section of food supporting member 102Separator 104.Space in container is divided into by separator 104 accommodates food supporting member 102The first Room 1011 and the second Room 1012 positioned at the lower section of the first Room 1011.Separator 104There is the guide surface 1042 of perforate 1041 including center.Guide surface 1042 is from its outward flange to openingHole 1041 gradually to the bottom angled of container 101, with guiding fall into the first Room 1011 grease,The material such as food debris and water is under gravity along guide surface 1042 to perforate 1041Move through perforate 1041 and enter second Room 1012.Guide surface 1042 can be such as Fig. 1Shown in the smooth conical surface or the other shapes such as curved surface or helicoid surface.DrawGuide face 1042 can also arbitrarily be set relative to the angle of inclination of the bottom wall 1013 of container 101,As long as 1041 entirety from outward flange to perforate of guide surface 1042 are to the bottom angled of container 101Can.
Advantageously, guide surface 1042 can relative to the angle of inclination of the bottom wall 1013 of container 101With more than 10 degree, so as to preferably by the material fallen on guide surface 1042 by gravity andAir-flow is directed to perforate 1041 nearby and fallen into by perforate 1041 in second Room 1012.
In the embodiment shown in Fig. 1, separator 104, which has, to be extended to outside container 101Handle 1044, referring also to Fig. 2.The kink of handle 1044 can be shelved on container 101Side wall on breach in so that separator 104 is supported in container 101.In the case,Food supporting member 102 can be directly placed on the guide surface 1042 of separator 104 and position.The handle 1044 of external container is extended to while the positioning for providing separator 104 supports,User has been also convenient for support separator 104 and the food being placed on it outside container 101Part 102 picks and places.
Alternatively, the bottom of separator 104 can also set supporting walls 1043.Supporting walls 1043Can extend to vertically container 101 bottom wall 1013 nearby with further by second Room 1012 withPeripheral region of first Room 1011 between separator 104 and the side wall of container 101 is isolated.
In the embodiment shown in figure 2, perforate 1041 is with from extending centrally outThe starfish appearance perforate of some foots.It is to be understood that perforate 1041 can be arbitrary shape,Including simple circular or polygonal openings, as long as it allows material to pass through from the perforate 1041.
When using 100 cooking food of air fryer, by the air of heating devices heat by gasFlow generating apparatus drives and forms thermal current.Thermal current flowing is by institute on food supporting member 102The food of receiving simultaneously heats to it.Grease, the water extracted from heated foodAnd the ventilative bottom that the material such as food debris to be come off from food passes through food supporting member 102Portion 1021 is dropped on the guide surface 1042 of the separator 104 of the lower section of food supporting member 102.Because guide surface 1042 is the bottom in the side of the perforate 1041 to center upwardly toward container 101Wall 1013 is inclined, and in the presence of gravity and combination air-flow, these fall into guide surface 1042Everywhere on material will be moved to along guide surface 1042 near the perforate 1041 at center, and lead toPerforate 1041 is crossed to drop into the second Room 1012 of the lower section of separator 104.
Because the guide surface 1042 of separator 104 is greatly by the first Room 1011 and secondRoom 1021 separates, the heating directly connected with the first Room 1011 above container 101Heat radiation caused by device is at least partly stopped by separator 104；Meanwhile by heaterThe thermal current of heating is also at least partly stopped by separator 104 and less enters second RoomIn 1012.Therefore, also it is reduced by convection current of the air to second Room 1012 and heat transfer.Thus, due to the stop of separator 104, the heat biography from the first Room 1011 to second Room 1012Pass and be weakened, and make it that the temperature of second Room 1012 is substantially less than the temperature of the first Room 1011,And the temperature of second Room 1012 is set to reach the level of the smoke point temperature less than the food cooked.So, due in cooking process the grease of caused food, water and food debris all lead in timeGuide surface 1042 is crossed to be routed away from the first Room 1011 of high temperature and enter less than its smoke point temperatureThe second Room 1012 of degree.These materials do not continue to participate in hot-air and followed in second Room 1012Ring and be still heated, thus be able to not will not be also heated to the heating means touch of high temperatureMore than smoke point temperature produce oil smoke.Simultaneously because the bottom of the container in second Room 1012The temperature of wall 1013 is also below smoke point temperature, even if these materials finally fall the bottom wall in containerOn 1013, it also will not be heated to smoke point temperature by the bottom wall 1013 of container and produce oil smoke.Therefore, the effect for decreasing or even eliminating oil smoke has been reached.
The size of the perforate 1041 in the center of guide surface 1042 is unsuitable excessive, in order to avoid undue weakening pointSpacing body 104 stops the effect of heat transfer.By being appropriately arranged with the size of perforate 1041, separateThe use of part 104 can make the temperature in second Room 1012 in the work of air fryer 100It is lower about 50 degrees Celsius than the temperature in the first Room 1011, to have the function that effectively to avoid oil smoke.
As shown in figure 1, advantageously, can also have on the bottom wall 1013 of container 101 and drawGuiding element 105.The sectional area of guiding piece 105 gradually increases from its top to bottom, and it is on the wholeSubstantially it is in cone, pyramid, helicon, conical butt, frusta-pyramidal or buttHelicon.Guide surface of the guiding piece 105 in the axial direction of container 101 with separator 104Perforate 1041 on 1042 is aligned, and guiding piece 105 has along from perforate 1041Level height nearby on the vertical direction of the bottom wall 1013 of container 101 gradually to away from instituteThe radial center for stating container 101 tilts the spigot surface 1051 of extension.Advantageously, guiding piece 105Top can be extend into by perforate 1041 in first Room 1011.Guiding piece 105 and perforateThere is appropriate space to allow the material for falling into the first Room 1011 to pass through the space between 1041Into second Room 1012.
The one side of guiding piece 105 can block most of region at the center of perforate 1041 and onlyThe gap of the periphery of perforate 1041 is reserved so that the materials such as grease will be by so as to further willFirst Room 1011 separate with second Room 1012 with reach preferably stop from the first Room 1011 toThe heat transfer of second Room 1012 is to realize the advantageous effects of the lower temperature of second Room 1012.
Meanwhile the spigot surface for tilting down extension from center to the periphery on guiding piece 1051051 should from the material edge that the first Room 1011 is fallen into thereon by perforate 1041 by further guidingSpigot surface 1051 moves to the direction of the radial center away from container 101.This will to fall intoThe material of second Room 1012 is deposited further away from perforate 1041, and this will cause these to fall intoThe material of second Room 1012 is further from the near zone of perforate 1041 due to being locally exposed toFirst Room 1011 and the influence of caused localized hyperthermia, so as to which these materials can be in second RoomLower temperature is kept in 1012.
Blocked and to the remote of material in addition, guiding piece 105 is considerable degree of to perforate 1041Leave the thermal current that the guiding in hole 1041 also prevent in the first Room 1011 and pass through perforate 1041Significantly enter in second Room 1012 and blow back the material fallen into second Room 1012 againInto the first Room 1011.
Fig. 4-5 shows air fryer second embodiment of the invention.Second realityApply the structure class of the air fryer of the air fryer of mode and the first embodiment of the foregoing descriptionSeemingly, and will be from food also based on the principle as described by the air fryer on first embodimentThe ventilative bottom 1021 of support member 102 fall into guide surface 1042 everywhere on collecting materialInto the second Room 1012 of the lower section of separator 104, to reach the temperature for making collected materialKeep below smoke point and avoid effect caused by oil smoke.
The air of the air fryer of the second embodiment and the first embodiment of the foregoing descriptionThe difference of fryer is that food supporting member 102 therein has air-locked side wall 1022, sideThe first space 106 is separated between the outer wall of wall 1022 and container 101；And separator 104Also include supporting walls 1043, separator 104 is supported on container 101 by supporting walls 1043Bottom wall 1013 on, and the ventilative bottom 1021 of food supporting member 102 and separator 104Guide surface 1042 between be separated with second space 107.First space 106 and second space107 be connection, to be formed in the first Room 1011 and pass through food supporting member 102Air circulation path a part.In the work of air fryer, air-stream generating device producesThermal current can from the top of food supporting member 102 enter the first space 106 and reach secondSpace 107, then it is re-introduced into food from the ventilative bottom 1021 of food supporting member 102Inside support member 102, so as to realize circulation of the thermal current inside and outside food supporting member 102.ShouldThe circulation of thermal current can improve the efficiency of the food in thermal current heating food supporting member 102,So as to improve the cooking efficiency of air fryer.
Advantageously, guiding piece 105 can be partially projecting into the first Room 1011 through perforate 1041In.It is located at the first Room from the spigot surface 1051 for tilting down extension of center to the peripheryPart in 1011 can also be used to guide thermal current.When foregoing circulation thermal current is from second space107 edges, which are flowed and encountered to the inclined guide surface 1042 of container bottom 1013, extend into the first RoomDuring spigot surface 1051 in 1011, the spigot surface 1051 being at an angle of with guide surface 1042 will drawBearing of trend of the heat conduction air-flow along spigot surface 1051 guides towards the top of container 101, i.e.,Thermal current is guided to enter food branch from the lower section of food supporting member 102 through ventilative bottom 1021In support member 102.Therefore, guiding piece 105 further increases the efficiency of thermal current circulation, fromAnd further improve the cooking efficiency of air fryer.
As shown in figure 4, guiding piece 105 may be formed as spiral shape, so as to spigot surface 1051Be formed as helicoid.The helicoid helps to guide thermal current to enter food branch with rotary motionIn support member 102, so as to further improve the efficiency of thermal current heating food.It should be noted that openThe shape in hole 1041 should match with the shape of cross section of guiding piece 105, to cause perforate 1041Edge and guiding piece 105 between space will not it is excessive and weaken separator 104 stop heatThe effect of transmission.
