Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the engagement of a link fitting and a grill grate in a cooking appliance such as a toaster oven.

(Prior art) Conventionally, this type of cooker has been used, for example, in the
As shown in Publication No. 112624, it had a structure as shown in Figure 3. In the figure, 1 is a link metal fitting, and after fitting one end to the door 2 so as to be rotatable,
A notch hole 3 formed at the other end is connected to a through hole 5 formed in a plate material 4 of the gridiron. Then, when the door 2 is opened toward the front (left side in FIG. 3), the grill 4 is also pulled out toward the front by the link metal fitting 1.

(Problems to be Solved by the Invention) In such a conventional configuration, after connecting the door 2, the link fitting 1, and the gridiron 4, the door 2 is attached to the cooking device main body (not shown). When one link fitting is engaged with the grill 4 and another link fitting is about to be engaged with the grill 4, or after engaging two link fittings, the door 2 is attached to the cooking appliance body. When attempting to do so, the link metal fittings and the grill grate often become disengaged, and the assembly is extremely inconvenient, as one must always hold one's hand in place to prevent the metal links from coming off.

This invention solves these problems,
It is an object of the present invention to provide a cooking appliance that does not come off after the link fittings and the gridiron are engaged and has greatly improved assemblability.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an inner casing forming a cooking chamber, a door for opening and closing the entire opening of the cooking chamber, and a front and rear portion inside the cooking chamber. In a cooking appliance comprising a sliding grill grate and a link fitting connecting the grill grate and the door, the link fitting is provided with a locking hole having a large opening width on one side in the sliding direction of the grill grate, The grill has horizontal plates at both ends, an upright piece perpendicular to the horizontal plate, a connecting part horizontally extending outward from the upright piece, and a locking piece connected to the connecting part and extending in opposite directions. and
One of the locking pieces is a vertical locking piece that is bent at a substantially right angle when inserted from the wide opening width portion of the locking hole, and is bent horizontally after insertion; The cooking appliance is characterized in that a length including the dimension of one locking piece is larger than a length of the locking hole in the sliding direction.

(Function) With this configuration, the vertical locking piece in the connecting part of the gridiron is bent at an approximately right angle and inserted into the locking hole of the link fitting from the wider opening width, and then bent horizontally after insertion. By making the length including the dimensions of the connecting part and the locking piece larger than the length in the sliding direction of the wire mesh in the locking hole, there is no fear that the link metal fittings and the grid will disengage, making it easier to assemble. There is no need to assemble in an awkward position while holding your hands, and a significant increase in work efficiency and man-hours can be expected.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 6 is an inner casing that forms the cooking chamber 7, 8 is a door that opens and closes the entire opening of the cooking chamber 7, 9 is a gridiron, and 10 is a link between the door 8 and the gridiron 9. It is a link fitting. 11 is a horizontal plate forming both sides of the gridiron 9; 12 is a connecting portion provided at the front of the horizontal plate 11 in the horizontal direction via an upright piece; 13, 14 is a connecting portion along the connecting portion 12; The locking pieces 13 are provided at the front and back when viewed from the direction of the door, and the front locking piece 13 is bent at a right angle before engaging the link fitting 10. 15 is link metal fitting 1
It is a fan-shaped locking hole provided in the front part of 0. This locking hole 15 does not necessarily have to be fan-shaped, and it is sufficient that the opening widths of one side and the other side of the hole are different. At this time, as shown in Figure 2, the locking hole 1
As shown in Fig. 2a, the size of the opening 5 is such that the locking piece 13 bent at right angles (minimum dimension A in side cross section) can fit therein (maximum dimension B: B>A). In addition, when the locking piece 13 is folded back horizontally after the connecting part 12 and the locking hole 15 are engaged as shown in Fig. 2b, the dimensions of one locking piece and the connecting part are added. Lengths C and D are both locking holes 15
The dimensional relationship is larger than the maximum dimension B of .

Next, a method of engaging the locking hole 15 provided in the link fitting 10 and the connecting portion 12 provided in the gridiron 9 will be explained based on FIG. 2. First, the locking piece 14 is passed diagonally through the locking hole 15 from the narrow side. Next, as shown in FIG. 2c, the connecting part 12 is rotated about its one end 16 as a fulcrum, and the vertically bent locking piece 13 is passed through the wide part of the locking hole 15 as shown in FIG. 2b. Insert up to the position. At this time, as shown in FIG. 2b, it is easier for the locking piece 13 to pass through the locking hole if the locking piece 13 is tapered or bent at the broken line. Next, the locking piece 13 that has been bent at right angles is folded back horizontally to complete the engagement.

At this time, lengths C and D, which are the sum of the dimensions of the locking pieces 13 and 14 and the connecting portion 12, are both larger than the maximum length B of the locking hole 15, so the engagement will not come off. do not have. In other words, unlike in the past, there is no need to assemble the link fittings and the gridiron in an unreasonable posture while holding the link fittings together to prevent them from disengaging even after they have been engaged, which greatly reduces work efficiency and man-hours. It is effective.

(Effects of the invention) As is clear from the above embodiments, the cooking device of the present invention has a vertical locking piece that is inserted into the locking hole and then bent horizontally, so that the connecting portion and one locking piece can be connected to each other. Since the structure is such that the length including the dimension can be greater than the length of the wire mesh in the sliding direction in the locking hole, the grill mesh will not only not fall off from the link fittings but also be easy to install. be able to.

In addition, with this invention, if the locking hole is made wider on the door side or made into a fan shape, the vertically bent locking piece will not necessarily be vertical, and even if it is slightly bent outward, it will not lock. The locking piece can pass through the hole where it is widest.

Furthermore, in the present invention, since the inside of the locking piece is tapered, the locking piece can be inserted into the locking hole more easily than one without a taper.
