Abstract

A heating cooker capable of preventing inflow of main body exhaust from a main body exhaust port to a main body intake port and preventing intrusion of moisture into the main body through the main body exhaust port.
In a cooking device, main body exhaust ports (9a, 9b) and a grill exhaust port (10) are formed on a rear upper surface of a top plate (2), and an exhaust port cover (13) covering these is provided. An exhaust through hole 15 is formed in the exhaust port cover 13 directly above the grill exhaust port 10, and a semi-extracted hole 14 is embossed in a range excluding this. The main body exhaust flows in a substantially horizontal direction along the inner surface of the exhaust outlet cover 13 and then exhausts vertically upward through an exhaust through hole 15 formed in a range immediately above the grill exhaust outlet 10. At this time, the main body exhaust is pulled toward the exhaust through-hole 15 by the ejector effect of the grill exhaust having a high wind speed to increase the wind speed.

Description

  The present invention relates to a cooking device, and more particularly to a cooking device having a grill in the main body.

A conventional cooking device has heating means (an induction heating coil, a gas burner, etc.) for heating an object to be heated placed on the upper surface (top plate portion) of the main body, and the heated object inserted into the main body from the front surface. And a grill box for heating an object (an electric heater, a gas burner, etc. are installed). And the smoke and hot air which generate | occur | produce in a grill warehouse are exhausted from the grill exhaust port formed in the top plate part via the exhaust pipe. Also, the inside of the main body is cooled by a wind flow formed by a cooling fan, and the wind flow means that the outside air sucked from the main body inlet formed in the top plate portion is subjected to the cooling, and then the top plate portion It is exhausted from the main body exhaust port formed in the above.
At this time, the main body exhaust port is arranged behind the grill exhaust port so that the smoke exhausted from the grill exhaust port does not contaminate the wall surface located behind the main unit, and the smoke exhausted by the air exhausted from the main unit exhaust port. An invention for preventing contact with a wall surface is disclosed (for example, see Patent Document 1).

JP 2002-89858 (page 3, FIG. 1)

However, in the invention disclosed in Patent Document 1, when the wind speed of the exhaust air from the grill exhaust port is compared with the wind speed of the exhaust air from the main body exhaust port, the former is larger than the latter, that is, the main body exhaust port. Since the wind speed of exhaust air from the main body is slow, the exhaust air from the main body exhaust port is pulled into the main body intake port and sucked into the main body, causing a so-called short cycle. There was a problem that the cooling performance of the main body was deteriorated due to the rise of the intake air temperature.
In addition, since the main body exhaust port is open, moisture may enter the main body via the main body exhaust port due to "spilling" or "blowing off" from the heated object. There was a problem of damaging the electrical parts.

  The present invention has been made to solve the above problems, and prevents inflow of exhaust air from the main body exhaust port into the main body intake port and allows moisture to enter the main body through the main body exhaust port. It aims at obtaining the heating cooker which can prevent.

The cooking device according to the present invention includes a main body including a top plate on which an object to be heated is placed,
Plate heating means for heating an object to be heated, which is disposed in the main body and placed on the top plate;
A control board disposed in the main body for driving the plate heating means;
A grill cabinet arranged in the main body and configured to allow food to be taken in and out from the front of the main body,
A grill heating means arranged in the grill for heating the food;
A grill exhaust port formed at the rear of the top plate for discharging smoke and hot air generated in the grill to the outside of the main body,
A cooling fan disposed within the body and for creating a wind flow in the body;
A main body inlet formed on the rear of the top plate for sucking outside air into the cooling fan;
A main body exhaust port formed at the rear of the top plate for discharging the wind flow created by the cooling fan out of the main body;
An exhaust port cover placed on the top plate and covering the grill exhaust port and the main body exhaust port;
Have
A through hole is formed immediately above the grill exhaust port of the exhaust port cover, and the wind flow discharged from the main body exhaust port together with smoke and hot air discharged from the grill exhaust port passes through the through hole. It is characterized by being discharged.

In the heating cooker according to the present invention, an exhaust port cover that covers the grill exhaust port and the main body exhaust port is placed on the top plate, and a through hole is formed in a range immediately above the grill exhaust port of the exhaust port cover. The discharged wind flow is discharged through the through hole together with the smoke and hot air discharged from the grill exhaust port.
Therefore, the wind flow discharged from the main body exhaust port is exhausted vigorously together with the smoke and hot air discharged from the grill exhaust port having a high wind speed, so that it is not sucked into the main body through the main body intake port. . In addition, since no through hole is formed in the exhaust port cover directly above the main body exhaust port, the water accumulated in the exhaust port cover drops into the grill exhaust port through the through hole, but enters the main body exhaust port. There is nothing to do. Therefore, the cooking device excellent in main body cooling performance and waterproofness is provided.

(Heating cooker)
1 to 5 schematically show a cooking device according to an embodiment of the present invention. FIG. 1 is a perspective view of the cooking device, and FIG. 2 is a state in which the top plate shown in FIG. 1 is removed. 3 is a top view of the cooking device, FIG. 3 is a perspective view showing the inside of the cooking device with the top plate shown in FIG. 1 removed, FIG. 4 is a partially enlarged view of FIG. 3, and FIG. 5 is a sectional view of FIG. It is.

1 to 5, the heating cooker 1 includes a top plate 2 on which an object to be heated is placed and a main body 3 formed under the top plate 2.
Inside the main body 3, heating coils 4 a, 4 b, 4 c (hereinafter collectively referred to as “heating coil 4”) for heating an object to be heated placed on the top plate 2, and the heating coil 4 Is provided with a control board 5, a grill cabinet 6 configured to allow food to be taken in and out from the front surface of the main body 3, and a cooling fan 7.

The cooling fan 7 is for cooling the outer periphery of the control board 5, the heating coil 4, and the grill cabinet 6, and external air is passed through the air cylinder 7 a from the main body inlet 8 formed on the rear upper surface of the top plate 2. Then, after sucking and sending out the inside of the main body 3, the air used for cooling is discharged from the main body exhaust ports 9 a and 9 b formed on the rear upper surface of the top plate 2.
In addition, a grill exhaust port 10 is formed on the rear upper surface of the top plate 2, and an exhaust cylinder 11 that connects the grill exhaust port 10 and the grill cabinet 6 is connected to the rear surface of the grill cabinet 6.

(Exhaust port cover)
An intake port cover 12 having an intake through hole 15 is provided immediately above the main body intake port 8 so as to cover the main body intake port 8.
An exhaust port cover 13 is provided immediately above the main body exhaust ports 9a and 9b and the grill exhaust port 10 so as to cover them. An exhaust through hole 15 is formed in the exhaust port cover 13 in a range immediately above the grill exhaust port 10 (a range surrounded by A-B-C-D in FIG. 4), and the same range as the through hole 15 except for this range. The “half punch hole 14” having an inner diameter is embossed.

(Wind flow)
When cooking grilled fish or the like in the grill cabinet 6, smoke or hot air (hereinafter referred to as “grill exhaust”) generated in the grill cabinet 6 is exhausted from the grill exhaust port 10 to the outside of the main body 3 through the exhaust cylinder 11. The More precisely, after flowing through the exhaust tube 11 toward the rear surface, the direction is changed vertically upward, and vertically upward via the exhaust through hole 15 of the exhaust port cover 13 provided immediately above the grill exhaust port 10. Exhausted.

On the other hand, inside the main body 3, the outside air taken in from the main body intake port 8 is sent out to the inside of the main unit 3 by the cooling fan 7, and after cooling the outer periphery of the control board 5 and the grill cabinet 6, the main body exhaust port 9 a, The air is exhausted to the outside of the main body 3 via 9b. That is, since no through hole is formed immediately above the main body exhaust ports 9a, 9b, the air that has passed through the main body exhaust ports 9a, 9b (the outside air used for the cooling, the temperature rises compared to before the suction). (Hereinafter referred to as “main body exhaust”) flows in a substantially horizontal direction along the inner surface of the exhaust port cover 13 and then passes through an exhaust through hole 15 formed in a range immediately above the grill exhaust port 10. Then, it is exhausted vertically upward.
At this time, the main body exhaust is pulled toward the exhaust through hole 15 and the wind speed is increased by the ejector effect of the grill exhaust having a high wind speed.

When cooking is not performed in the grill cabinet 6, grill exhaust does not occur, but the main body exhaust passes through the main body exhaust ports 9a and 9b and flows in a substantially horizontal direction along the inner surface of the exhaust port cover 13, and then the grill. The gas is exhausted vertically upward through an exhaust through hole 15 formed in the range immediately above the exhaust port 10.
That is, the main body exhaust is exhausted far away from the main body intake port 8 by a distance that flows in a substantially horizontal direction along the inner surface of the exhaust port cover 13. Therefore, the occurrence of a “short cycle” that sucks the main body exhaust together with the outside air is prevented.

(effect)
As described above, the cooking device 1 prevents the occurrence of a short cycle because the discharge position of the main body exhaust and the outside air intake are separated. In particular, when cooking in a grill, the exhaust of the main body is facilitated by suction due to the ejector effect of the grill exhaust. Therefore, the cooling performance of the main body is improved.
In addition, since there is no through-hole leading to the outside directly above the main body exhaust port, moisture enters directly into the main body via the main body exhaust port when the object to be heated is "splashing juice" or "blowing off" Thus, it becomes possible to protect the electronic components and the like disposed inside the main body. Therefore, maintainability and durability are improved.
Furthermore, not only the exhaust through-hole 15 but also a half-cut hole 14 in which the exhaust through-hole 15 is visually recognized in substantially the same form is integrally formed on the entire exhaust port cover. Therefore, the design of the exhaust port cover is secured.

  As described above, the cooking device of the present invention can be widely used for various cooking devices having a grill heating chamber because the cooling performance and durability are improved and the design is ensured.
