Description

Oven is improved

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

An object of the present invention is to provide a kind of helpfully, or provide the public baking box of useful selection at least overcoming above-mentioned shortcoming.

When drawer 5 is extracted out in baking box, and dividing plate 10 when being thus lifted to the position a contingent problem be that food or food byproduct for example grease splash on the baking box 1, and especially may splash on the control panel 12 of front side, baking box top.The preferred embodiment of baking box 1 of the present invention comprises control panel protector 31, will be introduced about Figure 17 a-d.

Control panel protector 31 is placed in the top rear that is connected to drawer 5, and comprises rigid panel or material, for example thermosetting plastic or similar material, the length of extending along the whole width of drawer back.The back edge of protector 31 be connected to by pivot on the last back edge of drawer 5 or near.When drawer was positioned at baking box, shown in Figure 17 c, protector 31 was switched to the approximate horizontal position around back edge, probably alignd with the top of drawer 5.Protector 31 is made into when protector is in this stored position, and its front upper edge is at angle shape a little upwards.Protector 31 is spring type or spring-loaded; both can pass through the spring (not shown); also can be at least in part by himself elasticity; like this when drawer 5 is extracted out in baking box 1 fully; as shown in Figure 17 a, 17b and 17d, control panel protector 31 by align up with the health of protector 31 around back edge 32 and a little forward at angle mode rotate and play a role.The height of protector 31 enough stops the circuit that directly splashes arbitrarily, or the straight line between control panel 12 and the dividing plate 10.When drawer 5 is pushed when getting back in the baking box, protector 31 rotates to stored position around back edge downwards, as shown in Figure 17 b.Protector 31 can also be placed on the baking box chassis, and when drawer 5 was pulled to the fully open position, protector was drawn forward and enters active position.

The drawer containment member

Can see that when drawer 5 is positioned at baking box 1, the major part of the heat that comes from upper and lower portion element or heater will directly enter drawer 5.But, unless be blocked in some way, the top edge top of the wall that some heated air will be by drawer 5, and enter the wall of drawer 5 and the space between the baking box inner surface.This will form the heated consequence of outer surface that we do not wish the sidewall 6,7 of the drawer 5 seen.It also makes the temperature in the oven cavity raise, thereby may cause being positioned at the baking box parts damages in this space.

In order to protect the heat-sensitive component that is positioned at this space, baking box 1 and drawer 5 have been assembled containment member to seal this slit.Containment member can be to help prevent heat to run out of the device that is fit to arbitrarily of drawer from the top top.Add a problem that the containment member of this form follows and be when door 2 and be opened and closed and drawer 5 is moved into and the dilatory and wearing and tearing of containment member when shifting out baking box.

Several different containment member that forms a part of the present invention will be introduced about Fig. 8 and Figure 12-16.

Can see, be that the slit between the inwall of the wall of drawer 5 and baking box 1 needs sealing.That is to say, each sidewall 6,7 of drawer 5, and need sealing between baking box 1 inside surface of side wall.The inner surface of baking box 1 rear wall, and also need sealing between the rear wall 8 of drawer 5.In the front portion of baking box, also need sealing between the inner surface of door 2 and baking box 1.Just, preferred before, back and side seal member realization complete preservation.For the protection that offers the best, will need to extend the entire depth of drawer 5 along the sealing of the side of drawer 5.Just, from the front portion of drawer 5 until the rear portion.

First embodiment that is applicable to the containment member in the slit between door 2 and the baking box surface will be introduced about Fig. 8 and Figure 12.Just, front sealing member.

Fig. 8 shows the baking box 1 of preferred embodiment, and wherein, drawer 5 is positioned at open position.

Baking box comprises chassis superstructure or block 16, and its front portion is placed in the place, front portion of oven cavity or towards the position of oven cavity front portion, stretches out downwards from the inside top surface of baking box 1.Each side of block 16 all has the slit, enters oven cavity with sidewall 6,7 processes that allow drawer 5.The rear wall 8 of drawer 5 is a shade below sidewall 6,7 so that its be fit to just block 16 below.Front sealing member or sealing gasket 15 are illustrated on the front portion of block 16 as shown in Figure 8, and level is extended along the whole width of block 16.Has vertical overlapping portion between the front portion of block 16 or forward part and the door 2.When the user closes door 2 the time, the inner surface of door 2 contact with front sealing part 15, with the leading edge manufacturing gastight seal along drawer 5.The further details of this device has been illustrated in Figure 12, its show baking box 1 the front portion the cross section or cut open and show side view.Door 2 is illustrated in the closed position, and the inner surface of door 2 withstands on the seal 15a (preferred form of seal 15).The example that is used for the suitable material of front sealing part 15a is a silicon.Seal 15a can also be made into textile fibreglass.Any other material with suitable thermal resistance and flexible nature also can be used.

Containment member (rear seal member) between the rear portion of drawer 5 and baking box 1 rear wall will be introduced about Figure 13.

Block 16 is made into its degree of depth size of rear portion (anterior to) size over half, so that its extreme lower position is positioned at the over top of upper surface of the wall of drawer 5 just.The outstanding downwards major part a shade below block 16 of the rear section of block 16 is so that have some vertical overlapping portions between the rear wall 8 of the rear section of block 16 and drawer 5.Rear seal member 15b be placed in this outstanding on, towards the open front side of baking box 1 and extend the whole width of block 16.When drawer 5 was placed baking box inner fully, the back of the rear wall 8 of drawer 5 was made airtight sealing in abutting connection with rear seal or sealing gasket 15b with the back edge along drawer 5.15a is the same with the front sealing part, and rear seal 15b can be made into silicon materials, textile fibreglass, or any other suitable material.

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.

Navel formula power transmitting apparatus (UMBILICAL POWER LINK)

Have and have for example dividing plate 10 of related apparatus or electric load, be fabricated into the difficult problem that the mobile drawer 5 of fan on the rear wall 8 and the following heater below the dividing plate 10 can take place is electric power to be provided how for these apparatus, or control signal, or both.The baking box 1 of this aspect comprises that power transmitting apparatus is to provide electric power to apparatus and electric load the mobile drawer 5 from stationary source.

The preferred embodiment of power transmitting apparatus will be introduced about Figure 19 a and 19b.

The function of power transmitting apparatus is to provide electricity to connect between the rear wall 8 of the stationary substrate of baking box 1 and mobile drawer 5, so that electric power can be provided on the drawer 5, and if desired, information can be sent on the drawer 5 and from drawer 5 and send away.Power transmitting apparatus is made up of following: chassis plate 33 is placed in the lower rear place of baking box 1 or places towards the lower rear of baking box 1.In a preferred embodiment, at least a portion of plate 33 is printed circuit board (PCB) (PCB) assembly.Chassis plate 33 provides connection or joins on the external bus power supply connecting portion, and can comprise transformer or power governor if desired.Preferably, connect the low-tension supply that not only is provided for partition movement and signal, the supply voltage that also provides element to use.Supply voltage be not in the product power supply-it is connected by power line provides.But independently power supply also can be placed on the drawer as drawer electric power and control signal.

Inner rotary connector or collar 35, the about midpoint between the front and rear of oven cavity, and amesiality a little place are connected on the static pivotal point 60 on baking box 1 substrate 61.Wire harness 34 connects from the power line of baking box 1 outside provides electric power, and from the rear wall of baking box 1, along the substrate 61 of baking box 1, until static pivotal point, and upwards enters the main body oven cavity by interior rotation collar 35 from chassis plate 33.This inner rotary connector 35 is rigidly connected on the end of hard swing arm 36.The pass through length of swing arm 36 and supported by swing arm 36 and protect of wire harness 34.Wire harness transmits low-voltage signal (control signal that for example is used for baking box 1 and partition movement electric power signal) and power line voltage.The other end of arm 36 is connected to by inner rotary collar or connector 37 and provides on the drawer plate 38 of connection to the electric power project on the drawer 5.In a preferred embodiment, at least a portion of drawer plate 38 is printed circuit board (PCB) (PCB) assembly.Arm 36 be not rigidity being connected of aerial lug 37, and arm 36 can slide in connector 37.That is to say, be slidably to connect between connector 37 and arm 36.This can be squeezed, and connects so that form slidably between connector 35 and the arm 36.In a preferred embodiment, drawer plate 38 is connected on the substrate 9 of drawer 5, preferably at the lower rear corner, and the meet of the substrate 9 of rear wall 8 and drawer 5.But it can be connected in any other suitable position, comprises the position away from drawer 5, for example on the substrate of baking box 1.When drawer 5 was opened and closed, arm 36 pivoted around interior and inner rotary connector 35,37, and through the circular arc of about 35 degree angles, drawer 5 is through the over top of arm 36 and connector 35,37.The advantage of this mechanism is that when drawer 5 is opened and closed the line in the wire harness 34 must be crooked through less relatively angle.That is to say that angle has been minimized.This has reduced the possibility of fatigue failure.Preferably, arm 36 has the form of hollow or U-shaped pipe, allows wire harness process in pipe." hollow " described in this specification should be understood that or hollow or U-shaped shape.Angle is as much as possible for a short time to be not strict necessary, and the overall structure of baking box parts will influence whole angle.But as mentioned above, preferably, angle is held less so that minimum fatigue.

It should be noted that in aforesaid preferred embodiment the moving-member of power transmitting apparatus ( rotary connector 35,37 and arm 36) is placed on the substrate of baking box 1.If desired, alternative structure can have a sidewall that is placed in drawer 5, and the moving-member between the sidewall of shell.

It shall yet further be noted that aforesaid power transmitting apparatus arm assembly can also be configured to be provided for the power supply connecting portion of any drawer type utensil.For example, similar device can be used to for example drawer dishdrawer that washes the dishes of the applicant's manufacturing of drawer dishwasher ^TM

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.

What introduce above is the preferred embodiment of baking box 1, has introduced drawer and door supporting mechanism, the preferred form of drawer 5 and heat shielding body 20.The alternative form of door and drawer supporting mechanism is introduced now.

The replacement device of door supporting mechanism is top pair of guide rails and the support that can one in front and one in back use with lower support and guide rail 3,4.As an alternative, the upper support guide rail can be used with the replacement lower guideway, and drawer and door are suspending in midair from supporting.

As another alternatively, the flexible multi-joint bar scissors mechanism of level can be used as a supporting mechanism, the drawer supporting mechanism, or both.

If preferably as an alternative, baking box 1 can be constructed to make drawer 5 must not be connected on the door 2, and can be independent of door 2 ground shift-ins and shift out baking box 1.All motions that the door 2 of this alternate embodiment will be independent of drawer 5 open and close.If the door 2 and the motion of drawer 5 are independently, baking box 1 can be constructed such that door 2 can be from the drawer horizontal opening on support system independently.As an alternative, door 2 can be the form that pivots or open rotationally on hinge.If the motion of door 2 and drawer 5 is independently, so independently the drawer supporting mechanism can be used.This can be any one alternate embodiment introduced above that is used for a supporting mechanism, or any other suitable mechanism.Drawer supporting mechanism and door supporting mechanism also can be combined into a mechanism that allows drawer 5 and door 2 self-movements, if desired.

As the preferred embodiment of introducing above, case or drawer 5 have sidewall 6,7, rear wall 8, and antetheca (being formed the part as door 2 in a preferred embodiment).

The alternate embodiment of drawer 5 is the structures with static rear wall.Just, have only movable side wall 6,7 and antetheca.The rear wall of the cooking cavity of this alternate embodiment is formed at the rear portion of baking box 1 or towards the rear portion of baking box 1 by static inwall.

Another alternative means that forms cooking cavity in baking box is the stationary substrate that is positioned at baking box 1.The upright side walls of drawer structure, antetheca and rear wall shift-in and shift out baking box 1, and when being positioned at baking box 1, align to form cooking cavity with stationary substrate.As an alternative, substrate and rear wall can keep static.The containment member that uses with the alternate embodiment of introducing above roughly with introduce above be used for the back of preferred embodiment and the front sealing member similar.

When using " drawer " speech in this manual, it typically refers to preferred embodiment.Just, have the case or the drawer of the open-top of four walls and substrate, and the wall of drawer and substrate shift-in and shift out baking box 1.But when reading this specification, " drawer " also should be understood that not have the structure of movable base plate or rear wall.When drawer was positioned at cabinet, static rear wall and substrate that the rear wall of cooking cavity and substrate are positioned in the cabinet formed.These selections can not be left out, unless otherwise indicated.

It shall yet further be noted that drawer 5 can be assembled front portion or the antetheca that has independent insulation if following sliding door or hinged door are used the horizontally sliding door 2 that replacement is introduced, do not contact any hot-air or thermal part when door 2 is opened, to protect the user.The drawer 5 of this alternate embodiment will slide into and skid off baking box 1 by being connected on the drawer supporting mechanism, the drawer supporting mechanism can be the part of a supporting mechanism, perhaps can be drawer supporting mechanism independently.

The alternative form of heat shielding body 20 is introduced now.
