Abstract

PURPOSE:To prevent the abnormal rise of temperature by providing an exhaust cover with large numbers of exhaust holes through which hot air is discharged from a heating cooker body provided on the upper part of an exhaust duct, a cover positioned on the upside of the exhaust duct, and an air pathway formed between the exhaust duct and the wall of a cooking chamber. CONSTITUTION:A heating cooker body 1 is housed in a cabinet 5, and a cooking stove 4 is placed above the cabinet 5. Hot air H from the heating cooker body 1 passes through an exhaust gas guide 10, and is discharged through the exhaust duct 11 from the exhaust holes of an exhaust gas cover 6. On the other hand, cold air C comes in by natural convection from a suction hole 12 provided on the front of the cabinet 5, flows along the wall 9 of a cooking chamber, passes through the back of the exhaust duct 11, and is discharged from the air holes of the cover 8. The wall 9 of the cooking chamber is cooled by the cold air C and the upside of the cover 8 is further cooled. The abnormal rise of temperature due to the staying of hot air on the cover and the heating of the cooking chamber can thus be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking device that is used in kitchens, galleys, etc. and uses gas laminated heat, high frequency waves, and the like as heat sources.

Conventional configuration and its problems.

Fig. 1 to Fig. 3 show a conventional example, Fig. 1 is a diagram of the built-in heating cooker, Fig. 2 is an external oblique -1 perspective view of the heating cooker, and Fig. 3 is a sectional view of the exhaust duct section. It is.

In FIG. 1, a cooking device main body 1 is installed between a sink 2 and a sink 3, and is installed below a stove 4 whose heat source is gas or electric heat.

The heating cooker main body 1 is housed in an exterior cabinet 5, and the hot air discharged from the △0 heat cooker main body is passed through an exhaust duct (not shown) or the like to a stove installed at the rear of the stove 4. The structure is such that exhaust air is exhausted from the exhaust hole γ of the exhaust cover 6. A cover 8 is in contact with the kitchen wall 9 as shown in FIG.

FIG. 2 shows a state in which the cooking device main body 1 is housed in a cabinet 6 and a stove 4 is placed on top of the cabinet 6.

FIG. 3 shows a configuration for exhausting air from the heating chamber provided in the cooking device main body 1, and shows an exhaust duct 11. The air is discharged to the outside through an exhaust cover 6 and through an exhaust hole 7.

In such a configuration, the exhaust duct 11 reaches a high temperature V? due to the hot air discharged from the heating chamber in the cooking device main body 1.
- Become. If the distance 1 between the exhaust duct 11 and the kitchen compartment wall 9 is narrow, the surface temperature of the kitchen compartment wall 90 may reach 100° C. or higher. Therefore, if the kitchen wall 9 is made of flammable material,
There was a risk of a fire. In particular, the upper part a of the cover 8 provided in contact with the kitchen wall 9 tends to become high in temperature due to exhaust heat, and also reaches the highest temperature due to conduction heat from the exhaust duct 11 and the exhaust cover 6.

In addition, since the hot air discharged from the exhaust cover 6 flows upward along the wall surface as shown by arrow f (1) in Fig. 3,
In addition, the upper part a of the cover 8 is not a hot air reservoir because it is cooled by the outside air, and has the disadvantage that it tends to reach an abnormally high temperature.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to provide a heating cooker that has a simple structure, prevents a rise in the temperature of the wall surface of the kitchen, and is free from the risk of fire. be.

Structure of the Invention In order to achieve all of the above objects, the cooking device of the present invention includes an exhaust cover provided on the top of an exhaust duct for discharging hot air from the cooking device main body, and having a large number of exhaust holes, and an exhaust cover of the exhaust duct. A cover located at the upper part and provided between the exhaust guide and the kitchen wall, and a vent hole are provided in the cover, and a ventilation path is provided between the exhaust duct and the kitchen wall. This has the effect of providing a highly safe heating cooker by preventing heating of the kitchen wall facing the exhaust duct and abnormal temperature rise caused by hot air pooling above the cover. be.

DESCRIPTION OF EMBODIMENTS An embodiment of the invention "f" will be described below with reference to FIGS. 4 to 6.

In Fig. 4, 1 (ζ) is a heating cooking device main body. The hot air H from the heated heating chamber (not shown) passes through the exhaust guide 10 communicating with the heating chamber, passes through the exhaust duct 11 as shown by the arrow, passes through the opening 9 of the exhaust cover 6, and then exits the exhaust cover 6. The air is discharged from the exhaust hole.Also, a ventilation hole is provided in the upper part of the cover 8, and the cooling air C flows in through the intake hole 12 provided at the lower front of the cabinet etc. by natural convection. , flows along the kitchen wall 9, passes between the rear surface of the exhaust duct 11, and is discharged from the ventilation hole of the cover 8, and this cooling air C cools the kitchen wall 9. However, the upper surface of the cover 8 is cooled.

In FIG. 5, reference numeral 13 denotes a ventilation hole provided in the upper part of the cover 8. By making this ventilation hole 13 as horizontal as possible and reducing the remaining dimension between the ventilation holes 13, the exhaust duct 11 and the exhaust The conductive heat from the cover 6 can be reduced and the heat shielding effect can be improved. 7 is an exhaust hole provided in the exhaust cover 6.

Figure 6 shows the flow of cooling air inside the cabinet 6 and the exhaust configuration from the heating chamber direction.
The lower part of the cover 8 is inserted and joined so as to cover the upper opening of the exhaust guide 10, and the upper part covers the exhaust hole 14 of the cover 8 to exhaust hot air H' from the cooking device main body 1 (not shown).
(i7, as shown by the arrow (↑), the exhaust is discharged from the exhaust hole 7 of the exhaust cover 6. By providing the ventilation hole 13 in the cover 8 above the exhaust duct 11, A ventilation path 15 is formed between the kitchen wall 9 and the kitchen wall 9, and the cooling air C flows in the direction of the arrow (ff), cooling the surface of the kitchen wall 9 and cooling the upper part of the cover 8 at the same time.

Furthermore, since the cooling air flowing out from the ventilation hole 13 rises along the kitchen wall 9 as shown by the arrow, the hot air H flowing out from the exhaust duct 11 can also be cooled.

In this way, according to the non-embodiment, a temperature rise in the kitchen wall 9 adjacent to the rear surface of the exhaust duct 11 is prevented with a simple configuration, and the upper part of the cover 8 above the exhaust duct 11 is cooled to block conductive heat. Heating has the effect of preventing an abnormal temperature rise in the kitchen wall 9 which is in contact with the upper part of the cover 8, where the temperature is highest, and eliminating dangers such as fire.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) By passing cooling air between the back surface of the exhaust duct and the kitchen wall, it is possible to prevent a rise in temperature of the kitchen wall surface on the back surface of the exhaust duct.

(2) The vent hole provided at the top of the cover eliminates the accumulation of hot air at the top of the cover, and reduces the heat conduction through the exhaust duct 7). This prevents abnormal temperature rises on the walls of the kitchen room and prevents dangers such as smoke and ignition.
