Description
Technical field
The present invention relates to convection oven and radiant type heating oven, or combination convection current and radiant type heating oven, or micro-wave oven, or combination microwave, convection current and radiant type heating oven, or the improvement of above-mentioned any combination.
Background technology
About baking box, the baking box of those family uses especially, long-standing problem is to add or baking oven is common when removing food is inconvenient to be placed.For example, in typical home-use cooker, cooking cavity is placed very lowly downwards and plate level closely usually, and the upper surface of cooker forms independently cooking zone and fries in shallow oil and similar operation to boil simultaneously.In order to add food or remove food in baking oven in baking oven, the user need stoop waist and the artificial dish that moves heavy and difficult operation or pot and advance and the chamber that goes out relative very little and inconvenient placement.Food when gastronomical process finishes, container and chamber all are hot, and this problem is just more outstanding, catch awfully hot dish or pot (and also will protect simultaneously their forearm and the hand hot surface that do not touch container or baking oven) because the user must stoop waist.In addition, when door was opened, the user also must tackle very hot air and hit their face and arm.
Most of baking boxs have the dividing plate or the support that can be pushed into baking box and pull out in the baking box, remove or insertion process helping.These push-pull device at fixed change to complexity from the simple support that is built on the baking oven side, the user must overcome dividing plate and support between friction to push or to pull out dividing plate, by somewhat complex design, and allow dividing plate to be moved to position more easily at an easy rate to the drawer guideway of thermal resistance and low friction ratio.The example of such dividing plate guide track system has been disclosed in WO 2004/025186.
The specification of several prior aries has been introduced and has directly been wanted to solve the food that is placed than the position of the user handled easily device of the problem of plate level closely.U.S. Pat 1,777,529 and U.S. Pat 1,851,183 all disclose the system of shelving with the motion of level and vertical clapboard, so that the baking box dividing plate can be moved out of baking oven, and move to the position that the user can obtain the food on the dividing plate more easily from the position near ground level.
In U.S. Pat 1,777, in the disclosed device, the user need stoop waist adjustable support is shifted out baking oven in 529.The user need shelve height by handle adjustment hand-manipulated, surpasses bigger distance if dividing plate need be moved, and for example moves on to the top of the more convenient placement of user from the bottom of baking oven, and operating grip can be very slow and very inconvenient.Utilize transmission system to change horizontal movement into vertical motion in order to the mechanism that realizes Height Adjustment.But gearratio is clearly discussed in this specification open, and clearly, for the travel gamut of its motion of moveable partition board, the system that is disclosed needs user's rotary handle revolution at double, has increased inconvenience.
U.S. Pat 1,851,183 disclose that a kind of can utilize in an embodiment introduce manually-operated but be indicated also can electrically operated two separate handle adjustment levels and the vertical system of shelving.Dividing plate is embedded into the formula sliding guide rail device and supports.
U.S. Pat 6,114,665 disclose a kind of system, and wherein, a cover baking box dividing plate is connected on the oven door removedly, or places to back boom from oven door.Oven door is sliding opening on slide block or similar component, and like this, it all remains in the perpendicular for whole range of movement.Independently dividing plate can be added in the storehouse or therefrom as required and remove.
Contingent another problem of such baking box is when door is opened, and can run out of hot-air in baking oven.Typically, when the user attempts to remove food or places food to the baking box dividing plate the time, these hot-airs are run out.These hot-airs may cause the user to be difficult to correctly place food, and feel very ill.Have, the user is easy to by mistake touch hot surface (for example dividing plate etc.), and injures themselves again.When making, face that hot-air hits the user takes place especially easily when they are instantaneous to cannot see.
U.S. Pat 2,133,639 disclose a kind of baking box of attempting to address this problem, and door and door supporting mechanism that it has horizontal opening have the mobile back plate or the wall that are connected to the dividing plate rear portion on the door.When door is in a fully open position, the open front that back in fact plate resistance has been kept off baking box.
In addition, another difficult point of such baking box is how to adequately protect to be positioned at the sensing unit of hot oven cavity.Along with baking box becomes increasingly complex, and can finish cooking function widely, baking box comprises that complicated controlling organization and temperature measuring equipment are just more usual and necessary.And no matter door is opened or is closed, and is used more in order to moveable partition board in oven cavity or the automation mechanism that carries out other autotask.A problem using such mechanism is how to protect them not to be subjected to oven cavity interior heat and influence of temperature variation.It is unpractical that these mechanisms are placed the back of the interior protective bulkhead of oven cavity, and the selection that has alternative mechanism concerning the user is helpful.
In addition, another known problem of convection oven is the even heating that how to realize whole cooking cavity.Use whole baking box fan or the hot-air in the fan circulation cooking cavity though we have known, the place that is heated may also can be developed, and causes cooking food inhomogeneous or dissatisfied.
Summary of the invention

The different embodiment that are used to form the side seal member between the wall of the sidewall 6,7 of drawer 5 and baking box 1 will be introduced about Figure 14 and 15.
Figure 15 has schematically shown a kind of form of the side seal member that forms a part of the present invention.Figure 15 is the cross sectional view of the last left-hand part of baking box 1, sees into baking box 1 from the front, shows left-hand side containment member 15c, the details of the left hand sidewall 7 of drawer 5 and block or chassis superstructure 16.Left-hand side containment member 15c comprises the sealing gasket 29 that is fixed on the arm 23 that floats, and the arm 23 that floats is connected on chassis superstructure or the block 16.Containment member 15c also comprises at least two rollers 24, lays respectively at the front and back, and is connected on the arm 23 that floats, when drawer 5 by shift-in or when shifting out baking box 1, roll along the sidewall 7 of drawer 5.On this position, the arm 23 that floats is in certain and compresses down.When drawer 5 arrived closed positions, each roller 24 was pushed in the depression 25 on the sidewall 7.Also therefore form sealing on the surface that the size of these depressions 25 can be arranged to make side seal pad 15c be shifted onto sidewall 7 by the arm 23 that floats.Similarly the device of symmetry is used on the opposite side of baking box 1.
The side seal member that substitutes is illustrated in Figure 14 and has suffered, and it is the cross sectional view of the last left-hand part of baking box 1, sees into baking box 1 from the front, shows left-hand side containment member 15d, the details of the left hand sidewall 7 of drawer 5 and block or chassis superstructure 16.Side seal member 15d comprises that the hard that is fixed on the spring pad 26 does not have friction or low friction ratio end 27.Low friction ratio end 27 is forced on the left hand drawer side wall 7 by the spring pad 26 that is connected on the chassis superstructure 16.Spring pad 26 keeps constant sealing function power between drawer side wall 7 and terminal 27.This side seal member 15d has and does not line up the advantage that is compensated at an easy rate arbitrarily between drawer 5 and the baking box 1.And, eliminated the needs of removing all moving-members by have the containment member that contacts with drawer side wall always.Moreover similarly the device of symmetry is used on other sidewall of baking box 1.Side seal member 15d is made into the size of extending along the cardinal principle entire depth of baking box, with the slit between the wall of the sidewall 6,7 of sealing drawer 5 and baking box 1.
Preceding and the rear seal member that alternative therewith side seal member uses together can be and the top the same material of introducing.
It should be noted that we wish to have a spot of heat leak when using the combining structure of the forward and backward and side seal member 15a, 15b, 15c and the 15d that as above introduce.Even the inventor wishes that drawer 5 can not be completely sealed, the integral sealing member will provide enough functions.
Another replacement seal member will be introduced about Figure 16 a and 16b.
The containment member of this alternate embodiment has been simplified sealing surfaces by the whole process on drawer 5 tops around the sealing of the girth of the upper surface of the wall of drawer 5.This containment member also has around the girth of drawer 5 and seals continuously, reduces the advantage of heat leak.
Figure 16 a shows the cross sectional view of the last left-hand part of baking box 1, see into baking box 1 from the front, show the left-hand part of containment member 15e, the left hand sidewall 7 of drawer 5 and will be considered to be different from above the block of the second chassis superstructure of by the agency of or the details of chassis superstructure 16.
The advantage that this containment member 15e has is that the surface of containment member 15e and drawer sealing surfaces (just, the upper surface of the wall of drawer 5) have similar profile around the top perimeter of drawer 5, and have reduced heat leak.And the wearing and tearing on the contact surface of containment member 15e have been reduced.
The containment member 15e of present embodiment comprises and can vertically move, and is unsteady member 28 and the sealing gasket 30 that drawer 5 forms lid.When the user promoted drawer 5 and enters baking box 1, the member 28 that floats was lowered by actuating system or actuation member, so that sealing gasket 30, around the whole girth at drawer 5 tops, contacted with the top surface of the wall of drawer 5.When drawer 5 is opened from the closed position or is mobile, actuating mechanism will be simultaneously from the top edge of drawer 5 or all edge heights float member and sealing gasket 30.The preferred embodiment of actuating mechanism will be introduced in more detail about Figure 16 b.
Be connected to the arm 28 that floats front and rear be outstanding straight up guide pins 59 of passing the heating element heater 39 and the second chassis superstructure 16.Guide pins 59 has and is connected to each roller of selling 59 upper ends 60, and each is taken turns 60 and rolls in horizontal plane.Each take turns 60 on the top of the second chassis superstructure 16 horizontal rolling.In the present embodiment, at least the top section of the second chassis superstructure 16 and rear section can carry out some limited motions in horizontal plane, and the part of the second chassis superstructure 16 is outstanding downwards at the rear portion of drawer 5, so that have vertical overlapping portion between the second chassis superstructure 16 and the drawer 5.When drawer 5 was closed, the rear portion of rear wall 8 contacted with the rear section of the second chassis superstructure 16, made it to be promoted backward by the rear horizontal towards baking box 1.When the second chassis superstructure moved to the baking box rear portion, scroll wheel guide pins 59 rested on its on-station position.The top of the second chassis superstructure comprises groove 61.When the second chassis superstructure 16 was mobile backward, groove 61 fell in the groove 61 so that take turns 60 below third wheel 60.This makes guide pins 59 land successively.This make to float arm 28 and sealing gasket 30 descend from the initial position that separates with drawer 5, to the top of drawer 5, make sealing.When drawer 5 was opened, roller 60 was upwards followed the tracks of groove 61 angled rear sides, and lift-off seal part 30 leaves drawer 5.
If desired, the spring (not shown) of vertically being located can be included between the second chassis superstructure 16 and the unsteady arm 28, correctly follows the tracks of to guarantee wheel 60, and positive sealing function power is provided between sealing gasket 30 and drawer 5.
In alternate embodiment, suspension hook that is formed or projection can be used to replace wheel 60, projection along the top slide of the second chassis superstructure 16 to navigate in the groove 61.
It shall yet further be noted that what the actuation member that is fit to was arbitrarily introduced above can being used to replace.For example, float that arm 28 and sealing gasket 30 can for example screw rod and worm gear make up structural motor straight up and move down by being connected to suitable system.
By using containment member 15a; or 15b; or 15c; or 15d; or 15e; or any combination of these containment members, or any other suitable containment member prevents that hot-air from running out of the space between the inner surface that enters drawer 5 and baking box 1 from drawer 5, sensitive components and baking box parts that protection is placed in this space can be by superheated.Another advantage is a cooking efficiency, because its needs less electronic the cooking cavity temperature to be remained on correct level.

Oven cavity top barrier body
The problem that the drawer type baking box has is the top that is difficult near oven cavity.Just, be difficult near below the top surface of baking box 1.In baking box 1 of the present invention, this difficulty is become more complicated by the wall of drawer 5, has more hindered approaching.In order to help to clean and maintenance, oven cavity top barrier body has been used.The preferred form of oven cavity top barrier body will be introduced about Figure 18.
As mentioned above, baking box 1 comprises the last heater 39 that can be used as grill element.Oven cavity top barrier body comprise be placed in heater 39 tops, the formula that the skids off top lining 50 between below last heater 39 and baking box top, it has covered the whole surf zone at top substantially.Top lining 50 can guide rail, roller or arbitrarily on other similar supporting mechanism to front slide, clean or maintain so that it is removed from baking box 1.Figure 18 shows the top lining 50 that is in " use " position (being shown as solid line among the figure), wherein lining 50 is placed the top of heater 39 on the baking box inside fully, also show and be in " extraction " position (being shown as dotted line among the figure), on this position, it is extracted out in the baking box at least in part cleans or maintains.
The heat shielding body
Another advantage of baking box of the present invention will be introduced about Fig. 2,4,5,6 and 7.
As can be seen, when drawer 5 was extracted out in baking box 1 or pulled out, the heat of sending from last heater 39 that is directly entered the cooking cavity that is formed by drawer 5 in the use entered the inside of baking box 1 with direct radiation, unless be directed to other place.The heat that radiation enters in the baking box 1 may damage sensing unit.The mechanical part that was subject to heat affecting may twist, and the parts that should be free to slide on another parts may block.The electric component that is heated the easily inefficiency that becomes, or lose validity.Therefore, do not wish that these heats are entered the inner space of baking box 1 by direct radiation.
In order to prevent its generation, the baking box 1 of preferred embodiment has been assembled heat shielding body 20.Preferably, heat shielding body 20 uses with the preferred embodiment of aforesaid drawer.
Heat shielding body 20 is placed in drawer 5 rear portions, and uses when drawer 5 is extracted out in baking box 1.In a preferred embodiment, shield 20 is roughly the plane and is the rectangular reflection plate, the folding stored position that enters when drawer 5 is placed in baking box 1 inside, and when drawer 5 is extracted out, open up into expanded position, as shown in Fig. 5,6 and 7 in baking box 1.
In a preferred embodiment, as shown in Fig. 2,6 and 7, when shield 20 is formed in it and is in expanded position and drawer 5 and is extracted out in baking box fully, will open to form the size of the cardinal principle horizontal plane below the last heater 39 that is positioned at baking box 1 just.In a preferred embodiment, shield 20 crosses the whole inner width of baking box 1 substantially.
The leading edge 21 of shield 20 is connected on the rear wall 8 of drawer 5.The back edge 22 of shield 20 is connected on the inner surface of baking box rear wall.Just, the inner surface of shell.The preferred form of shield 20 is folded into half by fold line between two parts or hinge 24, when shield when the plan-position of using moves to stored position, be folded into this two halves.The medium-sized pact of each of shield 20 and second half are measure-alike.Each part all enough hard so that they in normal operating condition, or its deadweight down can be crooked and sagging.Hinge 24 and shield 20 be urged so that when drawer 5 by when open position advances in the baking box 1, two parts of shield 20 are folding downwards, and upwards folding and not last heater 39 interference.
Preferably, the upper surface at least of shield 20 is made by heat-reflecting material.Tinsel for example.
Preferably, the front portion of heat shielding body is placed towards the top of drawer.But, if heat shielding body 20 by with the back edge at baking box rear portion downwards at angle, then clearly have the effect of partly shielding effect body at least.Can see,, but be positioned at position, highest and lowest position intermediate, for the lower portion of baking box 1, also will have the effect of partly shielding effect body at least if shield 20 can not be placed towards the top of baking box.Shield 20 allows it to use with the baking box of different internal structure in locational flexibility.
As mentioned above, preferably, the heat shielding body uses with the preferred embodiment of aforesaid drawer 5.But, the heat shielding body can also with have the non-drawer type baking box that is similar to aforesaid membrane support mechanism, or the dividing plate of prior art can be used together by the baking box of extracting out in baking box.In the baking box of this type, the leading edge 21 of heat shielding body will be connected on the back edge of dividing plate, or the correct position place in the membrane support mechanism.For example, the turning of heat shielding body can be connected on the rear portion of membrane support body or lifting support 46, so that dividing plate is driven forward, shield works from the stored position to the expanded position.When mentioning the heat shielding body and be connected in the membrane support mechanism, this should be understood that or preferred embodiment in the rear portion of drawer 5, or the back edge of dividing plate, perhaps membrane support mechanism, perhaps any other suitable position.
Should also be noted that, the essential advantage of using aforesaid heat shielding body is that drawer 5 or door 2 or both distortions are by from having prevented in fact (just, the distortion or the angulation of drawer 5 on slide block or other supporting mechanism or door 2 prevent that door or drawer are from position seamlessly transitting to the another location).Heat shielding body 20 will prevent the generation of twisting, because it can keep drawer to align with slide block or other supporting mechanism.Preferably, the material of shield is enough hard to transmit this advantage.
In a preferred embodiment, baking box 1 comprises a dividing plate 10.The user may need extra dividing plate space, for example, and in order to cook two batches of foods simultaneously.The baking box that is known in the art has the dividing plate of two or more vertical stackings, so that different food can be placed on the vertical height different in the baking box, highly roughly corresponding to temperature provinces different in the baking box.Between different baking box height, be difficult to realize the variation more effect more natural than temperature.The user also is difficult near the lower clapboard in these stacked structures.If desired, in order to realize and the similar result of many dividing plates baking box of prior art that baking box 1 can be made with the width of oversize, so that the dividing plate spatial class of a dividing plate 10 is similar to the dividing plate space of two dividing plate baking boxs in the prior art.Two or more heaters of independently going up can be used side by side, so that the food on opposite two sides can be cooked respectively in the baking box, and have only a side of last heater to be activated, or on starting on the different power levels different piece of heater.If desired, space bar can be added between the side of dividing plate, separating food, and makes temperature difference.
Another possible solution is to use different cooking cavities, and they can be by the different temperature conditions of easier setting as required.This is probably impossible for most users, because it needs two baking boxs usually.This is very expensive, and takies the space that does not provide in most family kitchens.
The about usually 600mm of the height of the baking box unit of standard prior art, and the size of baking box is configured to be put into below the calibrated altitude table top, table top is between 900mm and 960mm (approximately) usually.
If use single dividing plate baking box 1, that introduce above for example, the whole height of unit can be reduced.For example, the height in chamber may be reduced to about 280mm from 900mm.If the oven cavity height in the middle of selecting-for example, 480mm, 1, one of the baking box that may be fit to two these height below a table top is piled up on another.This has each baking box 1 and all is totally independent of another advantage.Therefore the temperature that the complete temperature control of each unit is independent of another will become possibility, and this need just to allow the food of very different cooking conditions to be cooked simultaneously.Should note, if two oven cavity in this way one be deposited in above another, if desired, shell or chassis can both be shared (just, comprise both), have two drawers, first drawer and second drawer, add that subsidiary first and second nest of drawers support, the membrane support body and independently heater all be comprised in the shared shell.And the control panel that is used for two oven cavity can be made into general, and allowing down, the control of baking box is placed on the height that human body can get at.
Double drawer baking box if desired, drawer and dividing plate can be by any members of by the agency of in this manual, (for example, on first drawer, use one type drawer to support, and on second drawer, use another kind of type) support if necessary with combining form.First and second drawers will be by independent supply capability or heating ideally, so that different food can be cooked under different temperature and timing condition in different drawers.
