Description

[Detailed explanation of the invention] Industrial application field This invention consists of a pair of left and right rotors installed inside the refrigerator, and a gondola supported by these rotors that carries the material and circulates it up and down. This invention relates to a roaster mainly used for commercial purposes, in which upper material is roasted by a burner and an upper burner horizontally suspended in the upper part of the chamber so as to be vertically movable.

Conventional technology A lower burner is fixed at the lower part of the chamber, and an upper burner is installed horizontally at the upper part of the chamber along a circulating gondola and can be raised and lowered to adjust the temperature of the flame. For example, there is a roaster equipped with a burner in the prior application of the present applicant.
There is one described in Publication No. 77625.

Problems to be Solved by the Invention In the conventional roaster described above, both ends of the upper burner are supported by an elevating guide mechanism consisting of a combination of rollers and vertical rails, and the rotating operation is carried out horizontally in a direction perpendicular to the side surface of the central part of the upper burner. A screw was attached to the inner end of the shaft, and the upper burner was moved up and down via a bell crank that swung in response to the screw moving forward and backward as the operating shaft rotated, so fat, oil smoke, etc. If it adheres to the mechanism, it tends to be difficult to operate, and the power transmission efficiency is poor, so a large amount of force is required. Therefore, it has been desired to improve the lifting and lowering mechanism of the upper burner so that it can be easily operated and the operability does not change even when fat, oily smoke, etc. are attached.

Means to Solve the Problems Therefore, the present invention provides rotors on the left and right sides of the chamber that support gondolas for carrying materials and circulate them up and down, a lower burner fixed at the bottom of the chamber, and a pair of left and right rotors. In a roaster equipped with an upper burner horizontally suspended upwardly so as to be freely raised and lowered, a lifting guide plate is attached to both ends of the upper burner, and the lifting guide plate is provided on the upper part of a pair of left and right inner wall plates forming the inside of the refrigerator. While it fits into the guide part that can be raised and lowered freely,
A rotary shaft is supported in parallel with the upper burner at almost the same height as the upper burner, and a left and right structure is provided at both ends of the rotary shaft that can swing along the outside of the inner wall plate using the rotary shaft as a fulcrum. A pair of levers are each fixed, and connecting pins protruding from the outer surface of the elevation guiding plate are fitted into elongated holes provided in the levers, and an index spring is attached to the tip of one of the levers between the lever and the lever. A handle whose outer end protrudes outside a vertical hole provided in the vessel body is connected via an expansion joint with a tensioned handle, and a latching pin is protruded from the side of the expansion joint. The present invention provides a roaster characterized in that a plate is provided in a vessel body with a multi-stage latching groove at an engaging position.

Function In the roaster of the present invention configured as described above, when the handle protruding outside the vertical hole of the vessel body is raised and lowered, the lever with the rotating shaft as a fulcrum swings along the outer surface of the inner wall plate, and the handle protrudes from the handle. The upper burner is raised and lowered together with the lifting guide plate via a connecting pin located close to the fulcrum side, and at the desired position, the latching pin on the side of the shaft joint integrated with the handle is connected to the latching pin provided in multiple stages on the plate provided on the body. By engaging with the stop groove, the vertical position of the upper burner can be fixed. Therefore, the lifting mechanism of the upper burner is simplified, and
Since the efficiency of force is improved, it can be operated easily, and it is also resistant to the adhesion of oils and fats, thus eliminating the above-mentioned drawbacks of the conventional method.

Reference numeral 9 denotes a rotating shaft whose both ends are supported on the upper end of the inner wall plate 1, and is horizontally suspended in parallel to the upper burner 6, and reference numeral 10 has its base fixed to both outer ends of the rotating shaft 9. , levers 11 are provided to be swingable between the inner wall plate 1 and the inner surface of the vessel F with the rotating shaft 9 as a fulcrum, and are provided protrudingly from the outer surface of the elevation guide plate 7. The connecting pin 13 connects the upper burner 6 and the pair of left and right levers 10 via the elevation guiding plate 7 by fitting into long holes 12 provided along the width direction, respectively, and the connecting pin 13 is located on the right hand side in FIG. A handle 16 extends from the tip of the lever 10 via an expansion joint 15 that is fitted with an index spring 14 stretched between the handle and the lever 10.
17 is a vertical hole provided in the body F so that the tip of the handle 13 projects outside the body; 18 is a locking pin protruding from the side surface of the expansion joint 15; , 19 is a plate fixed to the inner wall plate 1, which is a part of the vessel F, with multiple stages of locking grooves 20 inclined downward in the depth direction at engagement positions with the locking pins 18.

In the figure, reference numeral 21 denotes an L-shaped receiving part attached to the front and back inside the upper part of the vessel F, and 22 has an outer edge 22' supported by this receiving part 21, and hinge shafts 23 provided on both sides of the inner edge. By being connected to the pair of left and right lifting guide plates 7, the ceiling plate 24 of the chamber f, which is provided to tilt as the upper burner 6 rises and lowers, is opened in a triangular shape as the ceiling plate 22 slopes. a shielding plate 25 for shielding the upper part of the inner wall plate 1;

This upper burner 6
The vertical position of the expansion joint is maintained by engagement between a locking pin 18 on the side surface of the expansion joint and a locking groove 20 formed in multiple stages in the plate 19.

Effects of the invention According to the present invention configured as described above and used as described above, the upper burner is connected to the lifting guide plates provided at both ends of the upper burner by fitting the connecting pin and the elongated hole. The upper burner is raised and lowered by swinging a pair of left and right levers that are centered on a rotating shaft that is horizontally mounted at the same height as the upper burner.
The lifting and lowering mechanism of the upper burner is simplified compared to the conventional device, and even if fat or oily smoke that occurs due to the use of the roaster adheres to it, the operability of lifting and lowering the burner will hardly be affected due to the direct lever operation structure. . In addition, since the upper burner and the lever with the handle are directly connected via the lifting guide plate, it is possible to use a lever that is long in the direction perpendicular to the upper burner, that is, in the depth direction, so there is less loss of force and it is lightweight. This has the practical effect of allowing the use of a roaster with excellent durability and operability, such as being able to be raised and lowered.
