Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an oven toaster that moves a grill net on which food is placed in and out of a heating chamber in conjunction with opening and closing of a front-end door.
[0002]
[Prior art]
As this type of conventional oven toaster, for example, there is the one shown in Japanese Patent No. 2831781 (conventional example 1). In this oven toaster, in order to allow the grill net to be taken in and out of the case in conjunction with the opening and closing of the door and to regulate the opening angle of the door, a partial arc-shaped cam is formed on the left and right reflectors that form the heating chamber in the case. And a straight support rod is bridged between the two cam-like elongated holes so as to be movable in the longitudinal direction of the cam-like elongated hole. And the door side portion of the grill net is hooked to the two protruding pieces provided at the left and right ends of the inner surface of the door.
[0003]
A coil spring is provided between the left and right wall surfaces of the case and the left and right reflectors forming the heating chamber. The coil spring is elastically biased in the direction of pulling the support rod toward the back of the heating chamber, and is supported by the compression restoring force of the coil spring. The rod is pulled into the heating chamber.
The grill is hooked on the door protrusion and the support rod, respectively, and can be removed.
And the said protrusion is made into the attitude | position along a vertical direction when the door is moved forward, and the notch hole by which a grill net is detachably hooked is formed. The cut hole is formed in a substantially T shape in the horizontal direction in a state in which the projecting piece is in the vertical direction, and is formed in a horizontal direction, and is a linear insertion / extraction port through which the tip of the grill net is taken in and out. And a first hook portion recessed upward and a second hook portion recessed downward on the back side of the insertion / extraction opening.
[0004]
Note that the insertion / extraction opening is set to have a width slightly larger than the diameter of the wire constituting the grill net so that the grill net can be easily attached and detached.
The first hook portion is a catch for preventing the grill net from easily coming off when the door is opened and closed in a state where a cooked product is not placed on the grill net or a light cooked product is placed.
The second hook portion is a catch for preventing the grill net from being easily detached when the door is opened and closed in a state where heavy food is placed on the grill net.
[0005]
Moreover, although what was shown by Unexamined-Japanese-Patent No. 20001-355860 (conventional example 2) has the whole structure substantially the same as the prior art example, the shape of the notch hole to which a grill is hooked differs, In addition to the first and second hook portions, the door includes a third hook portion that is continuous with the first hook portion and is cut toward the door side, and the heavy food is placed on the back side of the grill net. The extension part of the support bar is hooked when the door is opened and closed.
[0006]
[Problems to be solved by the invention]
However, in the above conventional example 1, when the door is closed in a state in which a heavy cooked food is put on the back side of the grille and placed, the grille may come off from the cut hole of the protruding piece of the door. In addition, the conventional example 2 is an improvement of the conventional example 1, and even if a heavy cooked food is put on the back side of the grill net, it is less likely to come out of the cut hole than the conventional example 1, In some cases, there was a problem that the net was removed.
[0007]
The present invention has been made to solve the above-described problems. Even when the door is closed with heavy food placed on the back side of the grille, the grille is detached from the door. An object of the present invention is to provide an oven toaster that can keep a cooked product on a grill net in a stable posture so as not to jump up in an oblique posture.
[0008]
[Means for Solving the Problems]
An oven toaster according to the present invention includes a door that opens and closes a front opening of a heating chamber, a support bar that is provided on the left and right side walls of the heating chamber and that is displaceably supported before and after the heating chamber, and below the inner surface of the door projecting from the left and right ends of the projecting pieces having a notch hole, a biasing means for biasing said support bar on the back side of the heating chamber, the incision hole of the door side portions of the frame portion is the protrusion And a grill net that is supported by the support rod and moves back and forth in conjunction with opening and closing of the door, and the cut hole is in a state in which the protruding piece is along the vertical direction. An insertion / extraction port that is formed in a substantially T shape in the horizontal direction and is formed in the horizontal direction and into which the door side portion of the frame portion of the grill net is inserted / extracted, and a first hook portion that is recessed upward on the back side of the insertion / extraction port and a downward direction An oven toe having a recessed second hook portion In terpolymers, the insertion opening of the switching interrupt hole of the left and right projecting pieces is one that is shifted from each other with respect to the first, second hook direction.
[0009]
Moreover, those the size of the deviation of the insertion opening of the switching interrupt holes are substantially on the outside diameter or the door side portions of the frame portion of the grill.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
1 is a perspective view showing a state in which the door of the oven toaster is opened, FIG. 2 is a side perspective view when the food is not placed in FIG. 1, and FIG. 3 is a side view when the door is closed from the state of FIG. 4 is a side perspective view showing a state in which a heavy food is placed in the center of the grill net in FIG. 2, and FIG. 5 is a side perspective view showing a state when the door starts to be closed from the state of FIG. 6 is a side perspective view showing a state when the door is closed from the state of FIG. 5, and FIG. 7 is a side perspective view showing a state when a heavy food is placed in the back of the grill net in FIG. 8 is a side perspective view showing a state when the door is started to be closed from the state of FIG. 7, FIG. 9 is a side perspective view showing a state when the door is closed from the state of FIG. 8, and A is the whole oven toaster Is shown.
[0011]
The bottom of the door 2 is hinged to the case 1 on the front surface of the case 1 of the oven toaster A, and the door 2 is attached to be openable and closable in a forward-turned state. In addition, the heating chamber 3 in the case 1 has a left and right reflector 4 installed with a required interval with respect to the left and right walls of the case 1 and a back with a required interval from the back wall of the case 1 to the ceiling wall. The reflector 5 is formed. Bar heaters 6 are installed at the upper and lower positions of the space surrounded by the reflecting plates 4 and 5.
[0012]
In the oven toaster of the present invention, the grill net 7 on which the food is placed can be inserted and removed in a substantially horizontal state in conjunction with the opening and closing of the door 2, and the opening angle of the door 2 is restricted to about 90 degrees and does not hang down. I am doing so. Therefore, a linear support rod 9 is bridged over a partially arcuate cam-like long hole 8 provided in the left and right reflectors 4 of the heating chamber 3, and protrudes to the left and right below the inner surface of the support rod 9 and the door 2. The grill nets 7 are respectively hooked on the protruding pieces 20a and 20b. Then, one end of a coil spring 10 disposed in the gap between the left and right side walls of the case 1 and the left and right reflection plates 4 is locked to the portion of the support bar 9 that protrudes outside the cam-like long hole 8. .
[0013]
Even if the coil spring 10 closes the door 2 and releases it by the elastic biasing force to be restored, the door 2 will not be opened without permission. The grill 7 is composed of a frame portion 7a made of a wire material and a plane portion having a fine network station portion 7b, and an L-shaped system stop piece as viewed from the side is provided at the back end side of each portion extending in the front-rear direction of the frame portion 7a. 7c is joined in a state of protruding downward. Note that B indicates a cooked food.
In this embodiment, in a form in which the door and the support bar 9 are connected by the grill 7, the door 2 is placed in a state in which a relatively heavy food is put on the back of the grill 7 (behind the support bar 9). Is closed so that the grill 7 is not detached from the door 2 side and the front of the grill 7 jumps upward.
[0014]
Specifically, projecting pieces 20 a and 20 b are provided on both left and right ends below the inner surface of the door 2. The projecting pieces 20a and 20b are provided so as to project substantially vertically with respect to the inner surface of the door 2 so as to be in a posture along the vertical direction when the door 2 is tilted forward with the fulcrum 2a as the center. The projecting pieces 20a and 20b are provided with laterally substantially T-shaped cut holes 21a and 20b, respectively, for detachably hooking the door-side corners of the frame portion 7a of the grill 7. In addition, in the state where the protrusions 20a and 20b are in a posture substantially along the vertical direction by moving the door 2 forward, a notch hole is formed along the horizontal direction and the door side portion of the frame portion 7a of the grill 7 is taken in and out. The insertion holes 22a and 22b of 21a and 20b are shifted from each other with respect to the direction of the first hook portion 23 and the second hook portion 24, and the insertion holes 22a and 22b are formed on the frame 7a of the grill net 7. Are shifted from each other with respect to the door side portion.
[0015]
That is, for example, when the dimensions of the insertion / extraction ports 22a and 22b in the direction from the tip of the projecting pieces 20a and 20b to the first hook part 23 and the second hook part 24 are a and b, the dimensions a and b are different. I'm doing it.
Further, it is preferable that the displacement of the insertion / extraction openings 22a and 22b is equal to or larger than the substantially outer diameter of the door side portion of the frame portion 7a of the grill net 7 (the outer diameter dimension of the door side portion of the frame portion 7a of the grill net 7). (1), it is assumed that “Iro> C” or “Ilo≈C”.
[0016]
In addition, the first hook portions 23a and 23b that are recessed downward on the back side of the insertion / extraction opening 22 are connected to the first hook portions 23a and 23b, and the second hook portions 24a and 24b are formed by cutting toward the door 2 side. It has a shape having.
[0017]
Next, the opening / closing operation | movement of the door 2 by the difference in how to put a foodstuff is demonstrated. First, as shown in FIG. 2, in the state where the food is not placed or the state where the light food is placed, the entire grill net 7 is not sunk down, so the door side portion of the frame portion 7 a of the grill net 7 is The protrusions 20a and 20b are hooked on the first hook portions 23a and 23b of the cut holes 21a and 21b. When the door 2 is opened in this state, the grill net 7 is always pulled to the heating chamber side by the coil spring 10, so that it is surely secured by the door side portion of the frame portion 7a of the grill net 7 and the first hook portions 23a and 23b. It is structured so that it cannot be easily removed.
[0018]
When the user tries to close the door 2 from this state, the grill 7 is pulled to the back side by the restoring force of the coil spring 10 and the door 2 is pulled, so that the door 2 is closed as shown in FIG. At this time, the door side portion of the frame portion 7a of the grill net 7 is caught by the first hook portions 23a and 23b of the cut holes 21a and 20b, and is in contact with the back side of the first hook portions 23a and 23b. The door side portion of the frame portion 7a of the grill 7 does not move to the insertion / extraction openings 22a and 22b. Therefore, the grill 7 does not come off from the cut holes 21a and 21b.
[0019]
Further, as shown in FIG. 4, when the relatively heavy cooked food B is placed in front of or in the center of the grill 7 in a well-balanced manner, the entire grill 7 is sunk downward, and the frame portion of the grill 7. 7a is hooked on the second hook portions 24a and 24b of the cut holes 21a and 20b of the projecting pieces 20a and 20b. In this state, since the weight of the cooked food B is stronger than the restoring force of the coil spring 10, the grill 7 is not drawn into the back. If the door 2 is to be closed from this state, as shown in FIG. 5, the door side portion of the frame portion 7a of the grill 7 is pushed in the direction of the arrow, and the door side portion of the frame 7a of the grill 7 is 2 The hooks 24a and 24b come into contact with the inner side of the hooks 24a and 24b, and the door side portion of the frame part 7a of the grill net 7 does not move toward the insertion / extraction port 22 by the force of pushing up the door 2. As shown in FIG. 6, the door 2 is closed. Therefore, the grill net 7 does not come off the insertion holes 22a and 22b of the cut holes 21a and 21b.
[0020]
Further, as shown in FIG. 7, in the state where relatively heavy cooked food B is put on the back of the grill 7, the back side of the grill 7 sinks downward with the support rod 9 as the center. The side of the frame 7a of the grill 7 is pushed in the direction of the arrow, and the door portion of the frame 7a of the grill 7 has a first hook portion 23a of the cut holes 21a, 20b, It is caught in 23b.
[0021]
Further, as shown in FIG. 8, when the door 2 is closed, the door side portion of the frame portion 7a of the grill net 7 floats upward, so that the door side portion of the frame portion 7a of the grill net 7 is removed. Since it is pushed in the direction of the arrow and moves so as to be in contact with the door side of the cut hole 21, it is easy to come off from the insertion holes 22a and 22b of the cut holes 21a and 21b of the projecting pieces 20a and 20b, but the left and right cut holes 21a and 21b Is shifted beyond the outer diameter of the door side portion of the frame portion 7a, so that both sides do not come off at once (Elo> C, or Euro≈C). The door side portion of the frame portion 7a of the net 7 is always in the cutout holes 21a and 21b of the projecting piece and does not come off.
[0022]
Further, when attaching the door side portion of the frame portion 7a of the grill 7 to the cut holes 21a and 20b of the projecting pieces 20a and 20b, the linear support rod 9 is movable in the longitudinal direction with respect to the cam-like long hole 8. Therefore, it can be attached one side at a time by making the grill net 7 slightly inclined. Thus, even if the door 2 is closed in a state where a heavy food is placed in the back of the grille 7 in an unbalanced manner by shifting the positions of the cut holes of the protrusions 20a and 20b, the protrusions 20a and 20b of the door 2 are closed. Therefore, the cooked product can be stored in the heating chamber 3 in a stable posture.
[0023]
【The invention's effect】
As described above, according to the present invention, the door that opens and closes the front opening of the heating chamber, the support rod that is provided on the left and right side walls of the heating chamber and is supported displaceably before and after the heating chamber, Projecting pieces projecting from the left and right ends below the inner surface of the door and having cut holes , urging means for urging the support rod toward the back side of the heating chamber, and a door side portion of the frame portion A grill net that is hooked into the cut hole , the back side portion is supported by the support rod, and moves back and forth in conjunction with opening and closing of the door, and the cut hole extends along the protruding piece in the vertical direction. The first hook that is formed in a substantially T shape in the horizontal direction and is formed in the horizontal direction and into which the door side portion of the frame portion of the grill net is put in and out, and is recessed upward on the back side of the insertion port. And an oven toe having a second hook portion recessed downward In terpolymers, the insertion opening of the switching interrupt hole of the left and right projecting pieces is, the first, since the deviation from one another with respect to the second hook portion direction, migraine heavy food on the far side of the top of Shoami Even when the door is closed in a state where it is put together, the cooked food on the grill can be kept in a stable posture so that the grill does not come off the door and jump up in an oblique posture.
