It is " preceding " close to the side of user when user is in face of scorching appliance doors side, the side far from user is " rear ".
The non-uniform problem in temperature field existing for equipment is scorched for existing, it has been found that causing temperature field uneven
The reason of to be primarily due to each inner wall of liner be plane, caused by leading to unsmooth flowing of the air-flow in liner, needle
To this problem, this application provides one kind to scorch equipment liner, the liner can be applied to oven, it is micro- scorch all-in-one machine, tool
Having micro-wave oven of oven function etc. to have toasting performance or steam box etc., equipment, especially volume are biggish scorches in equipment.Such as
Shown in Fig. 1 and Fig. 2, liner is formed as the shell structure of open front, and the inner wall of liner includes left side wall surface 1, right side wall surface
2, rear surface 3, top wall surface 4 and wall surface 5, wherein at least one inner wall are formed at least partially as curved surface, curved design
The air velocity distribution in liner can be improved, fundamentally solve the problems, such as that existing oven temperature field is non-uniform, so that in liner
Temperature field in chamber is more uniform, to greatly improve the cured effect for scorching equipment.
Curved form becomes from middle part to the direction far from interior gallbladder intracavity or the face being recessed close to the direction of interior gallbladder intracavity, leads to
The mode for crossing this integrally bending can be realized in each orientation to the effect of the uniform flow of air-flow, it is preferable that curved form become by
The face that middle part is recessed to the direction far from interior gallbladder intracavity so, it is possible to improve liner volume while improving air velocity distribution.Example
Such as, curved surface can gradually be recessed to the direction far from interior gallbladder intracavity from its outer edge to its geometric center, what formation was integrally recessed
Curved surface, preferably spherical surface, for another example curved surface can also be a part on cylindrical surface.Curved surface is preferably arranged to spherical surface or cylinder
These more regular shapes of face, on the one hand facilitate the processing of liner, on the other hand can more homogenize air velocity distribution.
The radius of curvature of curved surface should not be too large also unsuitable too small, the excessive air flow method that will affect in the middle part of interior gallbladder intracavity, mistake
It is small, do not have the effect for homogenizing air velocity distribution, it is preferable that when curved form becomes spherical surface, the volume L of spherical radius r and liner
Relationship be L/r=0.05 to 0.15, further preferably 0.1；When curved form becomes a part on cylindrical surface, cylindrical surface

Wherein, the inner wall for being provided with curved surface can be one, be also possible to multiple, can be set according to specific requirements
It sets, curved surface can be formed as on inner wall for part, it is highly preferred that inner wall is entirely formed as curved surface, to further increase
Optimization to air velocity distribution, in one embodiment, wall surface 5 are formed as curved surface, are preferably formed into middle part to far from liner
The curved surface of the direction recess of chamber, exists in this way, enabling to fall on water, greasy dirt on wall surface etc. while optimization airflow flow field
The middle part of wall surface 5 is collected under the guiding role of curved surface, to facilitate cleaning of the user to liner；In another embodiment
In, left side wall surface 1, rear surface 3 and right side wall surface 2 are formed as curved surface, thus in the enterprising promoting the circulation of qi stream in direction around perpendicular
It homogenizes, in another embodiment, top wall surface 4, left side wall surface 1, wall surface 5 and right side wall surface 2 are formed as curved surface, thus in ring
Around the direction of the horizontal median axis of liner, enterprising promoting the circulation of qi stream is homogenized.In a further preferred embodiment, left side wall surface 1, right side
Wall surface 2, rear surface 3, top wall surface and 4 wall surfaces 5 are all formed as curved surface, it is further preferred that being respectively formed as depicted in figs. 1 and 2
For middle part to far from interior gallbladder intracavity direction be recessed curved surface, in this way, as shown in figure 3, can be formed in liner circumferential direction air-flow,
Air-flow can be circulated along the A in Fig. 3 to along top wall surface 4, left side wall surface 1, wall surface 5 and rear surface 3, can also be along Fig. 3
In B circulated to along left side wall surface 1, rear surface 3, right side wall surface 2 and door inner wall (not shown), thus in liner
Form uniform flow field in inner cavity, guarantee in being heated evenly everywhere in gallbladder intracavity, avoiding the occurrence of food, locally cooked-on part is half-cooked
The problem of.
Preferably, it is smoothly connected between adjacent inner wall by fillet surface 6, in this way, reduction air-flow can either be reached
Resistance, the effect in optimization airflow flow field, and the corner or spot as yet untouched by a clean-up campaign of liner can be reduced, facilitate user to carry out the inner wall of liner clear
It is clean.Fillet surface 6 is preferably big R fillet, in order to clean and guarantee the effect of optimization to air velocity distribution, for example, transition is bent
Face 6 is a part on cylindrical surface, and the relationship of the volume L of the radius R and liner on the cylindrical surface is L/R=2.4 to 2.6, further
Preferably 2.5, certainly, the radius R on cylindrical surface can not be excessive, the excessive volume that will affect liner.
Further, as shown in fig. 4 a, it should not be cleared up due to being easiest to accumulation dirt at three adjacent two-by-two inner walls,
And air-flow here turning when cause largely to decay, be based on this, it is preferable that (example is as shown in figure 1 for three adjacent inner walls two-by-two
Rear surface 3, right side wall surface 2 and wall surface 5) in, smoothly connected by fillet surface 6 between two inner walls of arbitrary neighborhood
It connects, to guarantee the air velocity distribution optimization of the intersection of three inner walls and the convenience of cleaning.
It is further preferred that being smoothly connected between adjacent two fillet surfaces 6 by connecting curved surface 7, in this way, such as Fig. 4 b institute
Show, air-flow can smoothly turn when passing through turning, and energy attenuation is seldom, in addition, since corner passes through the company of similar fillet
Connect 7 transition of curved surface connection, very convenient cleaning, to eliminate corner or spot as yet untouched by a clean-up campaign.In a preferred embodiment, adjacent two-by-two
Three inner walls formed three fillet surfaces 6, by taking Fig. 4 b as an example, rear surface 3, right side wall surface 2 and wall surface 5 are adjacent two-by-two,
Connect two-by-two, is smoothly connected by fillet surface 6 between every two adjacent wall surface, so that three fillet surfaces 6 are formed, three
The connection curved surface 7 at position that a fillet surface 6 crosses simultaneously connects three 6 transition of fillet surface, and the connection curved surface 7 is preferred
It is spherical, on the one hand facilitate processing, on the other hand can obtain optimal air velocity distribution.The radius R of the spherical surface and the appearance of liner
Product L relationship be L/R=2.4 to 2.6, further preferably 2.5.
Preferably, liner multi-sheets provided by the present application surround, and plate is formed as curved slab, can by die casting, roll
The modes such as system are formed, and since plate is curved shape, the problems such as there are stress concentrations are easy, for this problem, the application
Type selecting is carried out to the material of plate, the preferred scope of the thickness of plate is 0.4 to 0.8mm, further preferably 0.6mm, plate
Material uses steel plate, further preferably cold-rolled steel sheet BTC1.In addition, the cleaning of greasy dirt for convenience, applies in the inner surface of plate
It is covered with enamel coating.
It is provided by the utility model to scorch equipment the inner wall of liner is formed at least partially as curved surface, it is set by curved surface
Meter improves the air velocity distribution in liner, fundamentally solves the problems, such as that existing oven temperature field is non-uniform, so that interior gallbladder intracavity
