In the particular embodiment shown in fig. 2 and 6, the adjustment assembly 40 includes a support structure 422 disposed on the mounting base 41, the support structure 422 sliding along the surface of the support base 30 as the adjustment assembly 40 moves up and down. Thus, the support structure 422 is abutted against the support base 30, so that the upper grill pan assembly 10 and the lower grill pan assembly 20 can be kept parallel.

Specifically, the supporting structure 422 is a second guide wheel, the second guide wheel is spaced from the first guide wheel 421 along the extending direction of the sliding way 31, and when the upper roasting tray assembly 10 is opened, the second guide wheel is separated from the supporting seat 30. As shown, the support structure 422 is disengaged from the support base 30 after the upper tray assembly 10 is opened. That is, the support structure 422 only provides a support point when the height of the upper grill plate assembly 10 is adjusted by rolling contact with the support base 30.

Of course, the support structure 422 may also be a support protrusion provided on the mounting base 41. The function of which is the same as that of the second guide wheel. The only difference being that they roll or slide along the support 30.

As shown in fig. 5 to 8, the projection of the support base 30 on the lower tray assembly 20 is L-shaped, the support base 30 includes a sliding section 33 and a stopping section 34, the sliding section 33 has a slide way 31, the stopping section 34 is connected with the sliding section 33 and extends toward one side of the adjusting assembly 40, and the support structure 422 can move along the surface of the stopping section 34.

It should be noted that the positioning recess 32 is disposed on a side of the stopping section 34 facing the positioning portion 50. In this way, the positioning portion 50 is made to easily enter or exit the positioning recess 32 to enable the adjustment assembly 40 to be locked or unlocked.

As shown in fig. 5 to 8, the mounting base 41 includes a support frame 413 and two support plates 412, the two support plates 412 are oppositely disposed to form an accommodating cavity therebetween, the positioning portion 50 is disposed in the accommodating cavity, the locking end of the positioning portion 50 can protrude from the accommodating cavity, the unlocking button 60 protrudes from the accommodating cavity, the first guide wheel 421 and the pivot structure 411 are both disposed on the support frame 413, and the support frame 413 is fixed to the support plates 412. Through setting up carrier plate 412, can all be blocked partial structures such as location portion 50, unblock button 60 by carrier plate 412, protect the part in holding the chamber like this to avoid the part to damage, effectively prolonged hinge structure's life.

In the embodiment shown in fig. 1 to 8, the frying and roasting machine further comprises an elastic restoring member 70, the carrier plate 412 has a positioning protrusion 414 protruding toward the receiving cavity, the positioning protrusion 414 is located in the sliding direction of the positioning portion 50, and the elastic restoring member 70 abuts between the positioning protrusion 414 and the locking end to provide a restoring force for the positioning portion 50 to move toward one side of the supporting seat 30.

Optionally, the resilient return 70 is a spring.

As shown in fig. 6 to 8, in order to make it more convenient for the user to adjust the height of the upper grill pan assembly 10 upward and to ensure that the upper grill pan assembly 10 can be maintained at the adjusted height after the height adjustment is completed, the two adjacent positioning recesses are separated by the ratchet. The ratchet has a stopping direction and a releasing direction opposite to the stopping direction, and the releasing direction is vertically upward. When the user adjusts the height of the upper grill pan assembly 10 in this embodiment upward, the locking end of the positioning portion 50 gradually withdraws from the positioning concave portion 32 where the positioning portion originally is located, moves in the releasing direction of the ratchet and moves along the surface of the ratchet, and after the locking end of the positioning portion 50 passes over the highest point of the surface of the ratchet, the elastic reset piece 70 applies an elastic force to the positioning portion 50 toward the positioning concave portion 32, so that the locking end of the positioning portion 50 enters the positioning concave portion 32 above, and the adjustment of the height of the upper grill pan assembly 10 in one level is realized. Since the ratchet has a unidirectional function and can function as a stopper for movement in the opposite direction, the locking end of the positioning portion 50 can be prevented from falling back into the positioning recess 32 of the original level by the ratchet.

The accommodating groove 51 provides an installation space for the elastic reset piece 70, and the installation reliability of the elastic reset piece 70 can be effectively improved. When the unlock button 60 is pressed, the operation projection 53 slides toward the tip of the V-shaped unlock notch 61, so that the two operation projections 53 approach each other.

As shown in fig. 1 to 8, the pivoting structure 411 has a pivoting hole 415, and a stop block 416 is disposed in the pivoting hole 415, the stop block 416 provides a stop surface 417, the connecting end 11 of the upper grill pan assembly 10 slides in the pivoting hole 415 and is in stop fit with the stop surface 417, and is fixed in position relative to the lower grill pan assembly 20 after the upper grill pan assembly 10 is opened to the angle a and/or the angle B. When the upper tray assembly 10 is opened, the connecting end 11 of the upper tray assembly 10 slides in the pivot hole 415. When the upper grill plate assembly 10 is opened to a certain angle, the connecting end 11 of the upper grill plate assembly 10 contacts the stop surface 417 of the stop 416, so that the upper grill plate assembly 10 is positioned after being opened.

Optionally, angle a is 90 to 100 degrees. Further optionally, angle a is 95 degrees. Thus, when the upper grill assembly 10 is opened to this angle, the user is facilitated to cook the food material within the grill.

Optionally, angle B is 175 to 185 degrees. Further optionally, angle B is 180 degrees. When the upper grill plate assembly 10 is completely opened, the upper grill plate assembly 10 is prevented from being excessively rotated downward, and thus the maximum opening angle B of the upper grill plate assembly 10 is limited to 180 degrees.
