Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cooking device, and more particularly to a cooking device having a configuration in which a liquid tank containing a heat medium such as oil is heated by a heating source such as a burner.
[0002]
[Prior art]
A cooking device such as a fried food manufacturing apparatus (hereinafter referred to as fryer) used to manufacture fried foods has a heat source such as a gas burner disposed below the oil tank corresponding to the liquid tank containing the fried oil, and the flame of the gas burner. Is provided with a configuration for directly raising the oil temperature by directly heating the bottom of the oil tank.
FIG. 3 is a schematic view showing a fryer that is an example of the heating cooker. In FIG. 3, the oil tank A is arranged in a casing B with its upper edge portion placed and fixed.
The casing B has a shape that can surround the bottom and the periphery of the oil tank A, and includes a combustion chamber B1 for disposing the gas burner C at the bottom.
The combustion chamber B1 is surrounded and sealed by a partition member D, and a space formed by the partition wall D is configured as an exhaust path from the combustion chamber B1 to an exhaust section (not shown). As an example, the partition member D is configured as shown in FIG.
[0003]
In FIG. 4, the partition member D includes a plate-shaped iron plate D1 forming an aggregate and a plate-shaped heat insulating material D2 using ceramic fibers or the like located on both sides of the iron plate D1 in the width direction. The bolts E and nuts F are integrated with the material D2 sandwiched therebetween. In such a partition member D, the temperature rise of the aggregate D1 is prevented by the heat insulating material D2.
[0004]
[Problems to be solved by the invention]
The partition member D that should be sandwiched by the heat insulating material D2 and not affected by the ambient temperature in the combustion chamber B1 (see FIG. 3) has an increased ambient temperature in the combustion chamber B1, for example, 1000 When the temperature reaches about ° C, the temperature of the aggregate D1 may rise even if the heat insulating material D2 is provided. For this reason, heat is dissipated by transferring heat to the aggregate D1 of the partition member D, the temperature rise in the combustion chamber is hindered, and the oil tank A may not be heated efficiently. This is because the heat radiation area is increased because the aggregate D1 is formed of a plate-like member. As a result, when the temperature of the combustion chamber B1 (see FIG. 3) reaches about 1000 ° C., it has been confirmed that the heat loss due to heat dissipation reaches 40% according to the experiment by the present inventor.
[0005]
An object of the present invention is to provide a heating cooker having a configuration capable of efficiently raising the temperature of a liquid tank by suppressing heat dissipation in a partition member in view of the problems in the conventional cooking device.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the invention according to claim 1 has a configuration in which a liquid tank containing a heat medium such as oil is disposed in the casing, and the temperature of the heat medium is increased by heating the liquid tank with a heat source.

It is characterized by being comprised with the plate-shaped heat insulating material which pinches | interposes an aggregate.
[0009]
[Action]
In the inventions according to claims 1 to 3, since the aggregate which is one of the members constituting the partition member is originally configured to have an area smaller than the area necessary for partitioning the combustion chamber, The heat dissipation area can be reduced. In particular, in the invention described in claim 2, the area can be reduced only by providing a frame member having four sides, and in the invention described in claim 3, the area can be reduced simply by forming a lath hole in the plate member.

【Example】
The details of the present invention will be described below with reference to the illustrated embodiments.
FIG. 1 is a perspective view for explaining a configuration of a partition member used in a heating cooker according to an embodiment of the present invention, and the partition member shown in FIG. 1 surrounds the combustion chamber B1 shown in FIG. Used to go.
In FIG. 1, the partition member 1 is composed of an aggregate 2 and a heat insulating material 3.
The aggregate 2 is composed of an iron frame member having side portions 2A corresponding to the upper, lower, left and right sides of the combustion chamber B1 (see FIG. 3), and is reinforced longitudinally at the longitudinal center of the partition member 1 except for the four sides. Side 2B is provided.
Such an aggregate 2 is manufactured by making a square hole in which a portion corresponding to a reinforcing side and four sides remain.
[0011]
On the both sides in the width direction of the aggregate 2, heat insulating materials 3 using ceramic fibers or the like are arranged, and the aggregate 2 is sandwiched by these heat insulating materials 3 and integrated with each other by connecting members 4 such as bolts.
As the heat insulating material 3, a plate member having an area corresponding to the partition area of the combustion chamber B1 is used, and the heat insulating material 3 is integrated with the aggregate 2 including the four sides of the aggregate 2 and the reinforcing sides.
[0012]
Since the present embodiment is configured as described above, the partition member 1 in which the aggregate 2 and the heat insulating material 3 are integrated with each other is attached to the periphery of the combustion chamber B1 to exhaust the heated exhaust gas from the combustion chamber B1. Configure the passage.
When the temperature in the combustion chamber B1 rises and reaches about 1000 ° C. as described in the prior art, heat conduction occurs to the aggregate 2 of the partition member 1, but the aggregate 2 originally forms the combustion chamber B1. Since it is made smaller than the area required for partitioning, the heat radiation amount is reduced according to the heat radiation area by reducing the heat radiation area when receiving heat. As a result, the heat loss in the combustion chamber B1 is suppressed due to the decrease in the amount of heat release, and the temperature rise of the oil tank (a member indicated by symbol A in FIG. 3 for convenience) is promoted.
[0013]
In the said Example, although the frame material was illustrated as a structure of the aggregate 2 of the partition member 1, in this invention, it is not restricted to this example.
FIG. 2 is a perspective view showing another embodiment of the partition member, and the partition member (indicated by reference numeral 1 ′ for convenience) shown in FIG. 2 is a plate having a size necessary for partitioning the combustion chamber B1. A large number of lath holes 2A ′ are formed in an aggregate composed of members (indicated by 2 ′ for convenience).
The aggregate 2 ′ is sandwiched between heat insulating materials (members denoted by reference numeral 3 in FIG. 1 for convenience) positioned on both sides in the width direction and fastened by bolts 4 in the same manner as the example shown in FIG. Are integrated with each other.
[0014]
Since the present embodiment is configured as described above, the aggregate 2 'of the partition member 1' is composed of a punching metal in which a number of lath holes 2A 'are formed. Originally, the area of the aggregate 2 'is made smaller than the area necessary for partitioning the combustion chamber B1, and the amount of heat released when receiving heat is reduced. As a result, the amount of heat from the heating source can be prevented from decreasing due to heat dissipation, so that heat loss to the oil tank is reduced and the temperature increase of the oil tank is promoted.
[0015]
【The invention's effect】
As is clear from the above embodiments, according to the inventions of claims 1 to 3, the aggregate, which is one of the members constituting the partition member, is more than originally required for partitioning the combustion chamber. Since it is configured to have a small area, the heat radiation area can be reduced. In particular, according to the invention described in claim 2, it is possible to reduce the area only by providing a frame member having four sides, and according to the invention described in claim 3, by simply forming a lath hole in the plate member. Can do. Thereby, since the amount of heat radiation is reduced according to the area reduction, the heat loss corresponding to this can be reduced, and the temperature rise in the liquid tank is not hindered.
