BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker provided with a cooking mechanism for rotating skewers.

[0002]

2. Description of the Related Art Conventionally, some microwave ovens and the like used as a heating cooker have a cooking mechanism for rotating skewers for cooking roast chicken, roast beef and the like. In other words, this cooking mechanism supports the both ends of the skewers sideways while holding the stuffed food in the skewer in the refrigerator, and heats the stuffed food with a heater or the like while rotating the skewer. It is supposed to.

[0003] When cooking is performed using such a rotary skewered cooking mechanism, it is important to set the heating time appropriately. However, conventionally, the cooker has to weigh the weight of the food in advance. A proper heating time is set based on the weight and the type of the food based on the cooking instruction manual.

[0004]

However, in such a conventional method of setting the heating time, it is not only necessary to separately measure the weight of the food every time cooking is performed,
The heating time must be determined by always referring to the cooking instruction manual, and extra work and time are required before starting the heating cooking, making the cooking complicated.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to set a skewer into which a food is stabbed without setting the weight of the food in advance. By simply setting the type of food from the menu, the appropriate heating time according to the type is automatically set, saving the time and effort of skewered cooking and making skewered cooking easy As an issue.

[0006]

According to the present invention, in order to solve the above-mentioned problems, one of the mutually facing side walls in a refrigerator into which the food is carried is inserted through the food. A receiving member for receiving one end of the skewer is provided on the other side wall facing the receiving member with a connecting support portion for connecting and supporting the other end of the skewer. The following configuration is adopted in a heating cooker in which a drive unit that rotationally drives is connected.

That is, in the microwave oven according to the first aspect of the present invention, the receiving tool is swingably supported by the support shaft toward one of the side walls, and the receiving tool contacts the side wall. A pressure sensor is provided at the position.

In a microwave oven according to a second aspect of the present invention, a cam projection is provided at the end of the skewer on the receiving member side, and a crank pressed by the cam projection is supported by a support shaft. It is swingably supported toward one side wall, and a pressure sensor is provided at a position where this crank contacts the side wall.

[0009]

In the cooking device according to the first aspect of the invention, when the skewers are set in the refrigerator with the food pierced, the weight of the food is transmitted to the pressure sensor via the receiving member, and the pressure sensor is activated. Since the pressure is applied, a detection output corresponding to the weight of the food is obtained from the pressure sensor. Therefore, if a calibration curve that determines the relationship between the heating time and the calibration value obtained by correcting the weight of the skewers from the detection output of the pressure sensor in accordance with the type of food is stored in advance in a memory or the like, By simply setting the type, the appropriate heating time according to the type is automatically set.

In the heating cooker according to the second aspect of the invention, after the skewers are set in the refrigerator with the food pierced, and then the skewers are rotated, the skewers are provided on the skewers with the rotation. Since the cam projections periodically contact the crank, the weight of the food is transmitted to the pressure sensor via the crank each time the projection comes into contact, and a detection output corresponding to the weight of the food is obtained from the pressure sensor. . As described above, in the heating cooker according to the second aspect of the invention, the detection output of the load state and the no-load state is periodically obtained, so that the subsequent detection signal processing is facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A case where the present invention is applied to a microwave oven having an oven function as a heating cooker will be described. In addition,
Of course, the present invention can be applied to an oven in which only a heater is arranged in a refrigerator.

Embodiment 1 FIG. 1 is a front sectional view of a microwave oven according to an embodiment corresponding to the first invention, FIG. 2 is an enlarged sectional view showing a main part of FIG. 1, and FIG. It is sectional drawing which follows the A line.

The microwave oven 1 of this embodiment is provided with a turntable 3 at a lower portion in a storage 2 into which a cooking object w is loaded, and a heater 4 at an upper portion, while opposing left and right side walls in the storage 2. 2a, 2b, one (left) side wall 2a
A receiving tool 8 for receiving one end of the skewer 6 inserted into the food w is connected to the other (right side) side wall 2b opposite to the receiving tool 8 so that the other end of the skewer 6 is connected and supported. A connection support portion 7 is provided. A drive unit (not shown) for rotating and driving the skewer 6 is connected to the connection support unit 7.

The receiving member 8 includes a mounting portion 8a having a U-shaped cross section on which the skewers 6 are mounted, a hook portion 8b for hooking the receiving member 8 to the side wall 2a, and a side wall 2a. The hook portion 8b is hooked on a support shaft 10 formed in a substantially U-shape, and both ends of the support shaft 10 penetrate the side wall 2a to the outside. It is fixed with a nut 12. As a result, the receiving member 8 is supported swingably around the support shaft 10 toward the side wall 2a.
A through-hole 2d is formed at a position where the pressurizing portion 8c contacts the side wall 2a. Further, a pressure sensor 14 is attached to the side wall 2a outside the storage 2 so as to face the through hole 2d.

As shown in FIGS. 4 (a) and 4 (b), the pressure sensor 14 has a U-shaped resin case 16 in which a disc-shaped large and small electrode sheet is placed. 18a,
A piezoelectric element 18 formed by laminating 18b is inserted, and a knob part 20 is integrally extended from the case 16. The tip of the knob part 20 is formed in a protruding shape on one surface side. While the other side faces the pressing portion 8c of the receiving member 8 through the through hole 2d of the side wall 2a. In addition, 22 is a lead wire of the piezoelectric element 18.

In the above configuration, to bake the food w in the oven, one end of the grilled skewers 6 into which the food w is stabbed is placed in the storage 2
It is placed on the receiving portion 8a of the receiving member 8 inside, and the other end is connected to the connecting support portion 7 to be supported.

In this state, the total weight of the food w and the skewer 6 is transmitted to the receiving member 8, and the receiving member 8 is to be rotated clockwise in FIG. The pressing portion 8c presses the knob 20 of the pressure sensor 14. Since this pressing force is further transmitted to the piezoelectric element 18, a detection output according to the total weight of the food w and the skewers 6 is generated from the piezoelectric element 18.

An approximately proportional relationship is established between the weight of the food w and the pressing force acting on the piezoelectric element 18. Therefore, a calibration curve that determines the relationship between the correction value obtained by correcting the weight of the grilled skewers 6 from the detection output of the pressure sensor 14 and the necessary heating time corresponding to the type of the cooking w is stored in a memory or the like in advance. In other words, only by setting the type of the food w, an appropriate heating time according to the type of the food is automatically set based on the correction value.

Embodiment 2 FIG. 5 is an enlarged sectional view showing a main part of a microwave oven according to an embodiment corresponding to the second invention, and FIG. 6 is a sectional view taken along line BB in FIG. 1 to 4 are denoted by the same reference numerals.

The microwave oven of this embodiment has a receiving member 9 for receiving one end of the grilled skewers 6 inserted into the food w on one (left) side wall 2a of the left and right side walls facing each other in the refrigerator 2. Are fixed by screws or the like (not shown). The receiving member 9 is provided with a mounting portion 9a having a U-shaped cross section on which the skewers 6 are mounted.

The end of the skewer 6 on the side of the receiving member 9 is formed in a columnar shape, and a cam projection 6a is provided at one position on the outer periphery thereof.

On the other hand, below the receiving member 9, a crank 11 which is pressed by the cam projection 6a of the skewer 6 is arranged. The crank 11 has an arm portion 11a abutting on the cam projection 6a, a hook portion 11b for hooking the crank 11 to the side wall 2a, and a pressing portion 11c extending toward the side wall 2a. The support shaft 10 is hooked on a substantially U-shaped support shaft 10, and the support shaft 10 is fixed to the side wall 2a. As a result, the crank 11 is swingably supported about the support shaft 10 toward the side wall 2a, and the pressurizing portion 11c of the crank 11 penetrates through the inside and outside of the storage 2 at a position where it contacts the side wall 2a. A hole 2d is formed, and a pressure sensor 14 is provided facing the through hole 2d.

Other configurations are the same as those in the first embodiment.

In the above configuration, in order to bake the food w in the oven, one end of the grilled skewers 6 into which the food w is pierced is placed in the storage 2
It is mounted on the mounting portion 9a of the receiving tool 9 inside, and the other end is connected to the connection support portion 7 to be supported.

When the skewers 6 are rotated together with the food w, the cam projections 6a provided on the skewers 6 periodically contact the arm portions 11a of the crank 11 with the rotation. After the cam projection 6a comes into contact with the crank 11, the cam projection 6a is rotated by the rotation of the skewer 6 so that the crank 1
In order to get on the first arm portion 11a, the skewer 6 is separated from the receiving portion 9a of the receiving tool 9, and the total weight of the food w and the skewer 6 is transmitted to the crank 11 as it is.
In response, the crank 11 attempts to rotate clockwise in FIG. 5 about the support shaft 10, so that the pressurizing unit 11 c presses the knob 20 of the pressure sensor 14. Since this pressing force is further transmitted to the piezoelectric element 18, a detection output according to the total weight of the food w and the skewers 6 is generated from the piezoelectric element 18.

In this configuration, as the skewer 6 rotates,
Since the crank 11 is periodically switched between a load state and a no-load state, each detection output in the load state and the no-load state is obtained from the pressure sensor 14 accordingly. Therefore,
If the detection output in the no-load state is set to the reference level, if the difference output between the two is obtained, the zero point correction has been performed, so that there is an advantage that the processing of the detection signal thereafter becomes easy.

[0027]

According to the first and second aspects of the present invention, even if the weight of the food is not weighed in advance, the skewer into which the food has been stabbed is set in the refrigerator before the food is weighed. Just by setting the type, the appropriate heating time according to the type of each food is automatically set, so that the time and labor for skewered cooking can be saved, and skewered cooking can be easily performed.

In particular, the configuration according to the second aspect of the present invention has an advantage that the detection signal can be easily processed because a periodic detection output is obtained with the rotation of the skewers.
