A method for installing a grill for a steaming and baking oven comprises the following steps:

(a) installing a liquid receiving disc 3:

firstly, a limit nut 13 is mounted on a mounting stud 9, a positioning ring 10 on the mounting stud 9 is inserted into a sleeve 8 at the bottom of a liquid receiving disc 3, positioning is convenient, butt joint is performed quickly, operation difficulty is low, and an elastic arching portion 12 on an elastic block 11 is extruded to enable the elastic block 11 to enter the sleeve 8 along with the positioning ring 10.

The two minutes when the location that passes through groove 14 on elasticity hunch portion 12 and the sleeve 8 outer wall meets, elasticity hunch portion 12 is worn out from the location is led to the groove 14, accomplish the equipment of installation double-screw bolt 9 and sleeve 8, when elasticity hunch portion 12 meets with the location is led to the groove 14, under the spring action, the elasticity hunch portion 12 reconversion is worn out the location and is led to the groove 14, and then restriction elastic block 11 freely deviates from sleeve 8, realize that installation double-screw bolt 9 and sleeve 8 are spacing to be connected together, and the operation is thus simple, the equipment degree of difficulty is low, high efficiency.

Thirdly, the limiting nut 13 on the mounting stud 9 is rotated upwards to enable the limiting nut 13 to abut against the lower end of the elastic block 11, the limiting nut 13 plays a role in blocking the lower end of the elastic block 11, so that no moving space exists at the lower end of the elastic block 11, the upper end of the elastic block 11 is fixed on the positioning ring 10, the elastic arched portion 12 is pressed and cannot drive the lower end of the elastic block 11 to move downwards, the elastic arched portion 12 is limited in the positioning through groove 14, and therefore the connection tightness of the mounting stud 9 and the sleeve 8 is improved, the mounting stud and the sleeve cannot be separated, the reliability is high, the operation is simple, and the strength is low.

Fourthly, aligning the mounting stud 9 to a mounting threaded sleeve 19 at the bottom of an inner cavity of the steam oven, rotating the liquid receiving disc 3 to enable the mounting stud 9 to be screwed into the mounting threaded sleeve 19, connecting the mounting stud 9 and the liquid receiving disc 3 into a whole body at the moment, and rotating the liquid receiving disc 3 to drive the mounting stud 9 to synchronously rotate, so that the operation space is large, the operation is simple and convenient, and the problems of small operation space, inconvenience in operation and the like caused by directly rotating the mounting stud 9 are solved; until the limit nut 13 is abutted against the installation threaded sleeve 19, the sufficient contact area between the installation stud 9 and the installation threaded sleeve 19 is ensured, the fixation is reliable, and the free release is not easy.

(b) Installing a baking tray 2:

firstly, an adjusting stud 25 is screwed on an L-shaped frame leg 6 of a base 1, and the end of the adjusting stud 25 faces downwards;

secondly, entangle the adjusting stud 25 on the L type frame foot 6 with the mounting through hole 27 on the ear seat 26, make 2 spacing installations of overware on base 1, support overware 2 through L type frame foot 6, overware 2 receives the horizontal power of leading in a plurality of directions simultaneously, unable lateral sliding, difficult freely drops, and is spacing reliable.

(c) Installing the hanging rack 20:

firstly, the adjusting stud 25 is sleeved with the column sleeve 28 at the lower end of the positioning support 24, the positioning support 24 is temporarily limited on the adjusting stud 25, the column sleeve 28 blocks the lug seat 26 from upwards separating from the adjusting stud 25, and the mounting reliability of the baking tray 2 is improved.

Secondly, the mounting columns 29 on the bottom surface of the fixed disk 21 are inserted into the positioning through holes 30 at the upper ends of the positioning brackets 24, so that the hanging rack 20 is limited on the positioning brackets 24, the fixed disk 21 is supported by the positioning brackets 24, the positioning brackets 24 in multiple directions are drawn together by the fixed disk 21, the positioning brackets 24 cannot rotate freely, the fixed disk 21 also bears transverse drawing force in multiple directions, cannot slide transversely, is not easy to fall off freely, and is reliable in limitation; the hanger 20 presses the positioning bracket 24 downwards, so that the column sleeve 28 is less prone to being separated from the adjusting stud 25, and the installation reliability of the positioning bracket 24 is improved.

(d) Mounting tray 32:

firstly, a support nut 43 is mounted on a support screw 39 of a bracket 31, the support screw 39 penetrates through a shaft sleeve 42 in the center of a fixed disc 21, the support nut 43 is supported by the shaft sleeve 42, the bracket 31 is limited on the fixed disc 21, the length of the support screw 39 penetrating through the shaft sleeve 42 is limited by the support nut 43, the height position of the support nut 43 on the support screw 39 can be changed through rotation, the height position of the bracket 31 is changed, the height position of the bracket 32 is further changed, the distance between the bracket 32 and a hanger 20 is changed, and uniform heating of food is facilitated.

The fixing arm 40 for clamping the bracket 31 is clamped by the limiting clamping groove 41 in the bottom surface of the inner ring 33, the tray 32 is limited on the bracket 31, the inner ring 33 is supported by the fixing arm 40, a grill assembly body is obtained, assembling operation is carried out outside, sufficient operation space is guaranteed, operation difficulty is reduced, operation efficiency is high, flexible adjustment is facilitated, and assembling quality is effectively guaranteed.

The frame ring 5 is clamped into the annular clamping groove 7 of the liquid receiving disc 3, so that the grill assembly is installed in the liquid receiving disc 3 in a limiting mode, the peripheral wall of the frame ring 5 is in close contact with the inner wall of the annular clamping groove 7, friction force is large, relative rotation between the frame ring 5 and the annular clamping groove 7 is not prone to occurring, and installation is reliable. In the use, the gridiron assembly body can follow and connect liquid dish 3 synchronous revolution, stirs the hot-air of inner chamber, changes its velocity of flow and flow direction for hot-air flows around food, has increased the area of contact of food with hot-air, does benefit to food and is heated evenly, improves and evaporates roast effect.

The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve the same technical problems and achieve the same technical effects are within the scope of the present invention.
