Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to the grill door of a table-type stove, and particularly relates to the improvement of the grill door applied to grill doors that have a handle at the bottom of the grill door. It is.

(Prior art) The above-mentioned grill door has a fixed see-through window and a handle, and the handle and see-through window become hot, making it difficult to use and posing a risk of burns.In particular, it is important to keep the handle at a low temperature. is an important issue. A conventionally known grill door in which the grill door is fastened to the water tray with bolts will be described with reference to FIG. 3.

The window glass 01 is clamped and fixed to the upper part of the handle body 02 and the window frame plate 3 with the front and back surfaces of the lower part in close contact with each other. Then, due to the roasting heat, the window glass
1 was heated to a considerably high temperature, and due to heat conduction from the upper end of the handle body 02, the grip part 021 also became quite high temperature, so that it was too hot to touch with bare hands, causing some difficulty in handling.

(Problems to be Solved by the Invention) Heat conduction from the above-mentioned window glass is cut off so that the grip part 021 does not get hot even when touched with bare hands, so that it can be handled without any trouble.

(Means for solving problems) This embodiment will be explained below using the drawings.

Standing wall 21 of the handle body 2 with a grip portion on the front side
A rib-shaped vertical wall 22 of a constant height is formed integrally at two places on the left and right sides of the window glass 1, and the lower and front surfaces of the window glass 1 are placed against the rear upper end of the vertical wall 22 for positioning. A notch 22a for holding the window glass 1 having a certain depth and a certain depth for forming a gap of a certain size t between the window glass 1 and the vertical wall 22, and the vertical wall 22 A boss 23a is formed on the back side of the handle body 2 at a position continuous with the vertical wall 22 or spaced apart from the vertical wall 22, for fixing the mounting piece of the window frame plate 3 for holding the window glass,
The window frame plate 3 is tightened to the boss 23a with the tightening screw 4 passing through the boss 23a, and is inserted into the notch 22a for regulating the position of the lower surface and the front surface of the window glass 1. The window glass 1 is sandwiched between the window frame plate 3 and the window frame plate 3.

(Function) Since the ventilation gap 5 is secured between the back side of the rising wall 21 and the front side of the window glass 1, the vertical wall 22,
A space A having the gap 5 is formed between the bosses 23a, through which air can flow in from below the back of the handle body 2 and pass through it, so that the back surface of the handle body 2 is always kept in contact with air at room temperature, and Standing wall 2
Heat conduction from the grill chamber to the grill chamber 1 is also very small, so the grip portion 25 is kept at a temperature close to room temperature.

(Example) This example is shown below in Figures 1, 2, 4, and 5.
This will be explained based on the diagram.

1 is a transparent window glass, 2 is a grip part 25 on the front side
, a resin handle body with an extension piece 26 behind the lower part; 3 is a window frame plate that holds the window glass 1; the window frame plate 3 has its upper edge and left and right edges bent into a U-shape in cross section The gripping piece 31 is bent and formed, and the window glass 1 is inserted and mounted from below. Further, the window frame plate 3 has mounting pieces 32 formed integrally with the back plates of the left and right grip pieces 31 and extending downward and slightly bent outward. Further, the handle body 2 has an upright wall 21 for attaching and fixing the window glass 1, and behind the upright wall 21, thin rib-shaped vertical walls 22 and 23 of a constant height are provided at each end. It is integrally formed in two places: inside and outside. An extra wall is left at the rear upper end of the vertical wall 22 to maintain a constant dimension t in the front direction for positioning the lower surface and front surface of the window glass 1 with respect to the rear end surface of the rising wall 21. A notch 22a cut at a substantially right angle having a certain depth and a certain depth is formed, and the mounting piece 3 of the window frame plate 3 described later is formed.
2 is tightened and tightly attached to the mounting surface 23b of the boss 23a.
The relationship is such that it is in close contact with 2a. 22b is a diagonal notch whose upper rear edge is largely chamfered, and the notch 22b has the same slope as the mounting surface 23b described later. A boss 2 is installed at the middle position of the vertical wall 23.
3a is integrally provided so as to be inclined downwardly forward from the back surface of the rising wall 21, and an oblique mounting surface 23b is formed at the upper part of the boss 23a.

Then, the inner surface of the mounting piece 32 of the window frame board 3 is attached to the mounting surface 2.
3b and while inserting and holding the window glass 1 from below, the lower edge of the window glass 1 is cut out 22a.
When the mounting piece 32 is placed on the bottom surface of the window glass 1 and tightened to the mounting surface 23b with the tightening screw 4 at a certain height position, the lower front edge of the window glass 1 will be cut out by the time the mounting piece 32 is tightly attached. It is sandwiched between the upright wall 21 and the mounting piece 32 in close contact with the vertical surface of 22a.

The front lower edge of the window glass 1 fits into the vertical surface of the notch 22a, and the gap 5 is secured between the front surface of the window glass 1 and the vertical wall 21.
A space A is formed which is separated in the left and right direction by the windows 2 and 23, and an opening 6 is formed between the lower end of the window glass 1 (indicated by a chain line S in FIG. 1) and the extension piece 26. is formed, and an L-shaped ventilation path is formed along with the gap 5 over almost the entire width on the left and right sides. Air flows upward through the L-shaped ventilation path (see arrow a). Reference numeral 24 is a rib-shaped vertical wall formed in the center. The head of the bolt 8 is held in a non-rotating state by the bolt holding portion 24a. On the other hand, the mounting piece 32 of the window frame board 3
The water tray 7 is fixedly attached to the window frame plate 3 by screwing the wing nut 9 into the bolt 8 which is inserted through the mounting plate 71 formed in front of the water tray 7 for the grill and tightening it. .

In the above embodiment, the vertical wall 22 is shifted inward and the boss 23a is directly formed integrally with the vertical wall 22 to serve as the mounting part of the mounting piece 32, or the upper part of the vertical wall 23 is extended and the boss 23a is formed directly on the vertical wall 22. It is clear that the purpose of the present invention can be achieved even if the notch 22a is formed in the boss 23a, and it is also clear that the internal and external positions of the vertical walls 22 and 23 may be reversed. 22a may be installed at two appropriate positions. Furthermore, it goes without saying that the mounting surface 23b may be a vertically straight plane and the window glass 1 may be tightened and fixed in the horizontal direction.

(Effect of the invention) In the present invention, a vertical wall having notches is formed at two places on the handle main body, leaving extra wall on the front side at the upper front end, and the lower front surface of the window glass can be positioned by the notches. As soon as a gap is reliably formed with the rising wall and the temperature of the space with the gap on the back of the grip is raised, air is sucked in from below and rises and passes through the back of the grip. It is insulated with an air layer to keep the temperature close to room temperature to prevent the grip from rising in temperature, and also has the effect of slightly lowering the temperature of the lower front surface of the window glass 1 at the top, eliminating the risk of burns during grilling work. It is valid.
