Description

[Detailed description of the invention] This invention relates to a roaster.

This type of device has a roasting chamber formed by an upper reflector, a rear reflector, a front reflector, and a main frame connected to both sides, and an inner cylinder. It is something to cover.

The front lens reflector is covered by the front case located under the glass door, but since this front case and the front lens reflector are separately attached to the main frame, the relative position of the front case and front lens reflector cannot be adjusted. Difficult to decide and assembly work is low.

In particular, the inner cylinder requires an opening at the bottom to dispose of incinerated waste, and an opening corresponding to the force glass door at the front, resulting in low rigidity at the front of the lower part, and it is also difficult to determine the opposing spacing at the front of the lower part of the main frame. It is.

The object of the present invention is to provide a roaster capable of eliminating the above-mentioned drawbacks.

This invention is provided with a main frame facing each other on both sides, and an upper reflector and a rear reflector whose both side edges are connected to these main frames, and which are opposed to the lower front surface of the rear reflector. A front lens reflector is provided which forms a roasting chamber together with the main frame and the upper reflector, and this front lens reflector and a front case facing each other at the front part are combined to form a front case unit body. The front case unit I/body is assembled to the main frame while the lower part of the main frame is held from the inside and outside by both outer edges of the front case unit body and protrusions adjacent to the outer sides of these both outer edges. It is characterized by:

Therefore, since the front case and the front lens reflector are assembled into the main frame after forming the front case unit in advance, the hassle of assembling the front case and the front lens reflector into the main frame while aligning them relative to each other is avoided. In particular, in the assembled state, the inward movement of the main frame is blocked by the outer edge of the front case unit body, and the outward movement is blocked by the protrusion, thus defining the facing interval of the main frame. At the same time, the structure is constructed so that the rigidity of the assembled structure can be increased.

An embodiment of the present invention will be described based on the drawings.

It is assembled by engaging with a slit-shaped locking hole 33 formed in the front part of and bending.

The boat bottom-shaped floor cover 34 can be moved back and forth by engaging hinge rods 35 with a semicircular cross section stamped on both sides thereof into elongated holes 36 formed in the lower part of the main frame 5, as shown in FIG. It is assembled so that it can move up and down, and when it moves forward, its front edge is supported by a protrusion (not shown) formed on the front lens reflector 26.

Further, a mounting metal fitting 37 is attached to the main frame 5 by engaging locking claws 38 formed at both ends thereof to the main frame 5.

These mounting fittings 37 are formed with a projecting piece 39 that is line-bonded to the outer surface of the main frame 5 and a projecting piece 40 that is long in the front-rear direction and extends outward.

The glass door 4 which opens and closes the front surface of the roasting chamber 2 consists of an outer frame 43 and an inner frame 44 each having an opening 42 in the center and drawn into a U-shaped cross section.

Holding parts 46 are formed on both side edges of the opening 42 of the inner frame 44 to slidably hold the plate glass 45 and to fix the movement of the plate glass 45 in the left-right direction. Holding parts 47 that support the lower edge of the glass plate 45 are formed, and from these holding parts 46 and 47 support pieces 4 that hold the glass plate 45 between the opening edge of the inner frame 44 are formed.
8 is formed.

The inner frame 44 is formed on the lower edge of the sleeve 1 to the hole 4.
The bosses 52 of the bundle 51 are fitted into the outer frame 43 while engaging the locking claws 50 of the outer frame 43 with the bosses 52 of the bundle 51 inserted into the upper part of the outer frame 43.
By screwing the screws 53 together from the inner frame 44 side, the inner frame 44, the outer frame 43, the bundle 51, and the glass plate 45 are assembled.

The legs 1 of the gridiron 11 are attached to the hinge pieces 54 inside the inner frame 44.
An arm 55 that is detachably connected to 2 is rotatably attached.

The legs 12, ie, the gridiron 11, are urged rearward by springs 56.

The outer casing 1 includes a U-shaped upper case 57 that surrounds the upper side of the main frame 5 and the upper reflector 4, and a back case 58.
and a side case 59 made of plastic that also serves as a handle and surrounds the lower part of the main frame 5.

The upper case 57 is reinforced against deformation in the left and right direction by screwing an arcuate reinforcing plate 60 to its front edge.

The upper case 57 has recesses 61 on both lower edges and these recesses 6.
A protruding piece 62 that is long in the front-rear direction and extends outward from the lower edge of 1 is formed.

A washer 63 is attached to the side case 59 as shown in FIGS. 7 and 8.
A screw 65 having a flange 64 for pressing is screwed on.

Then, the upper edges of the side cases 59 are fitted into the recesses 61 of the upper case 57, and the side cases 59 are tightened with screws 66.
Attach it to the mounting bracket 37 using the above-mentioned steps.

At this time, as shown in FIG.
The projecting piece 62 on the lower edge of the main frame 5 is held between the upper and lower sides, and the lower edge of the main frame 5 is supported from below.

At this time, the tips of the screws 65 protrude into elliptical holes 68 formed on both sides of the lower edge of the glass door 41 to serve as a hinge, and the protruding pieces 39 of the mounting bracket 37 are joined to the main frame 5, and the protruding pieces 39 of the mounting bracket 37 are joined to the main frame 5. 40 is joined to the inner surface of the recess 61 of the upper case 57.

Furthermore, a horizontally long projecting piece 69 is formed on the rear edge of the upper part of the upper case 57, as shown in FIG. 12, to be joined to the upper surface of the reinforcing plate 6.

A heat shielding piece 70 bent in a U-shape is formed on the lower edge of the back case 58, and a notch 71 is formed on the bottom side of the heat shielding piece 70.

A locking groove 73 of a cord protector 72 engages with this notch 71 as shown in FIGS. 9 and 10.

As shown in FIG. 12, the locking claw 74 formed on the upper part of the rear case 58 is engaged with the slit hole 75 formed on the rear edge of the upper case 57, and the upper edge and both sides of the rear case 58 are fitted. Connect the joint 76 to the upper case 57 and side case 59.
and the back case 5 with screws (not shown).
8 is fixed to, for example, the main frame 5 of the inner cylinder 3.

As described above, the assembly of the outer casing 1, the inner casing 3, and the glass door 41 itself and the assembly of the three components are performed.

In such a configuration, the upper part of the main frame 5 is connected to the upper reflector plate 4.
and the reinforcing plate 6, and the strength of the rear edge is strengthened by connection with the rear reflector plate 17.

Since the front lens reflector 26 and the front case 25 are assembled into a unit as the front case unit body 25a and then attached to the main frame 5, the relative positioning of the front lens reflector 26 and the front case 25 is necessary. At the same time, the troublesomeness of having to assemble it to the main frame 5 can be eliminated.

Its unitization can also be made very easily by the locking hole 31 and the locking claw 30.

Further, when the front case unit body 25a is attached to the main frame 5, not only the locking claws 32 of the front case unit body 25a are engaged with the main frame 5, but also the outer edge 28 is engaged with the inner surface of the main frame 5. Since the protruding portion 29 is joined to the outer edge of the notch 27 of the main frame 5, the facing interval of the main frame 5 is accurately determined and securely fixed, and the rigidity of the inner cylinder 3 is increased.

In particular, the outer edge 28 contacts the upward slope 14 of the main frame 5 and also fixes vertical movement with respect to the main frame 5.

Further, the recess 61 and the protruding piece 62 of the upper case 57 are engaged with the side case 59, and the rear case 58 is engaged with the protruding piece 74 of the upper case 57 with the upper case 57 while The outer casing 1 is formed by fitting the edges, and finally the outer casing 1 itself is fixed and connected to the inner cylinder 3 by a small number of screws including the screws 66. Moreover, the screws 65 of the side case 59 At the same time, the glass door 41 is rotatably held, thereby simplifying assembly.

Even in the case of the glass door 41, the plate glass 45 is held by only one inner frame 44, so when the opposite inner frame and outer frame are connected with screws while holding the glass between them as in the conventional case. As shown in the figure, it is possible to eliminate the inconvenience of the glass breaking or play in the plate thickness direction due to variations in the bonding force due to the screws.

Furthermore, although there is a gap between the upper case 57 and the inner cylinder 3, on the top surface, the protrusion 69 is joined to the reinforcing plate 6 that reinforces the main frame 5, and on the side, the recess 61 and the protrusion 62 Since the mounting bracket 37 is sandwiched between the main frame 5 and the inner surface reinforced by stamping, the strength of the outer frame 1, especially the upper case 57, is extremely strong.

Further, since the cord protector 72 is fitted into the notch 71 of the rear case 58 and is prevented from being removed from the side case 59, it can be easily attached.

Furthermore, the heat shielding piece 70 formed on the back case 58 protects the device from temperature rise without using any other members.

When using, place the object to be roasted on the grill 11 and turn on the heater 7.
Roasting is performed by applying electricity, and by forming the bending piece 15 that has a slope 14 and bends inward at the lower part of the main frame 5, the volume of the roasting chamber 2 can be reduced. As a result, thermal efficiency can be improved.

In addition, the front lens reflector 26 is also located at the lower part of the rear reflector 17.
Also, the heat directed downward is reflected toward the upper gridiron 11, but heat can also be reflected by the slope 14 of the main frame 5.

Therefore, roasting time can be shortened.

Since the reflection effect by the slope 14 is performed without adding a separate reflecting member, the structure can be simplified.

Further, since the volume of the roasting chamber 2 is reduced by reducing the dead space below the grill 11, there is no restriction on the size of the object to be roasted that can be placed on the grill 11.

Since this invention is constructed as described above, the front case and the front lens reflector are assembled into the main frame after forming the front case unit in advance, so that The trouble of assembling it to the main frame can be eliminated, and in particular, in the assembled state, the main frame is prevented from moving inward by the outer edge of the front case unit body and by the protrusion, Therefore, it is possible to determine the distance between the main frames and increase the rigidity of the assembled structure.
