Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device, and more particularly, to a cooking device having a structure in which an oil tank corresponding to a liquid tank containing a heat medium such as oil is heated by a heat source such as a burner. .

[0002]

2. Description of the Related Art A cooking device such as an apparatus for producing fried food (hereinafter referred to as a "fryer") used for producing fried food is provided with a heat source such as a gas burner at a lower portion of an oil tank containing fried oil, and a flame of the gas burner. In many cases, a configuration in which the bottom of the oil tank is directly heated to raise the oil temperature is used. FIG. 2 is a schematic view for explaining the configuration of the above-mentioned conventional heating cooker. In FIG. 2, an oil tank A is disposed with its upper edge placed and fixed in a casing B. The casing B has a shape capable of surrounding the bottom and periphery of the oil tank A, and is provided with a gas burner C mounted and fixed on the bottom.

[0003]

The temperature of the gas burner C mounted and fixed on the bottom of the casing B increases when the combustion is started. Therefore, gas burner C
The heat of the gas burner C is also transmitted to the casing B on which is mounted and fixed, and the temperature of the casing B rises. Since the casing B also serves as the outer wall of the cooking device together with the support of the oil tank A, the temperature rises due to the heat of the gas burner C being transmitted. May be dangerous if touched. In addition, since the outer wall portion has a very large contact area with the outside air, the heat radiation area is increased, thereby easily removing heat from the gas burner C. For this reason, the temperature rise in oil tank A tends to be slow, and it is difficult to obtain a rise in oil temperature required for cooking. As described above, in the conventional cooking device, the heating source such as a gas burner is supported in a state of being directly contacted, and the peripheral wall of the casing integrated with the supporting portion also serves as the outer wall of the cooking device. There is a drawback that when touched by human hands, there is a case where it is dangerous and heat radiation from the outer wall reduces the amount of heat received in the oil tank, so-called heat loss increases.

An object of the present invention is to provide a structure capable of preventing overheating of a casing supporting a liquid tank containing a heat medium and suppressing heat loss in view of the above-mentioned problems in the conventional heating cooker. To provide an overheated cooking device.

[0005]

In order to achieve this object, according to the first aspect of the present invention, a liquid tank containing a heat medium such as oil is disposed in a casing, and the liquid tank is disposed below the liquid tank. In a heating cooker provided with a configuration in which the temperature of a heat medium is raised by a heat source, the heat source is supported in a non-contact state with respect to the casing, and a heat insulating material is disposed on the supporting portion.

According to a second aspect of the present invention, in the heating cooker according to the first aspect, the casing is provided with a heat insulating material on an outer surface of a wall portion.

[0007]

According to the first aspect of the present invention, since the heat source is not in contact with the casing, and furthermore, the heat insulating material is disposed on the supporting portion, no heat is transmitted from the heat source to the casing. This suppresses a rise in the temperature of the casing.

According to the second aspect of the present invention, since the heat insulating material is disposed on the outer surface of the casing, the heat radiation of the casing due to the contact between the outer surface and the outside air is suppressed.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a schematic view showing a cooking device according to an embodiment of the present invention. In the drawing, a cooking device 1 includes an oil tank 2 corresponding to a liquid tank and a casing 3. Oil tank 2
It is composed of a deep-bottom bat that can accommodate a heat medium O such as oil using a corrosion-resistant and heat-resistant conductor such as stainless steel, and a flange 2A formed near the upper portion thereof.
Is mounted on and fixed to a support portion of a casing described later.

The casing 3 has a double wall structure in which an inner wall and an outer wall are formed using a heat-resistant material, and a flange 3A1 for mounting and fixing the oil tank 2 is provided on the inner wall 3A. A heating source 4 such as a gas burner is disposed at a position facing the bottom of the oil tank 2. Note that the heating source 4 is not limited to a burner, and a heater may be used. The outer wall 3B is a portion that supports the inner wall 3A and forms the outer wall of the heating cooker 1, and heat insulating materials 5 and 6 are disposed between the outer wall 3B and the bottom of the inner wall 3A where the heating source 4 is disposed and on the outer surface. Have been. Asbestos and ceramics containing glass wool are used as the heat insulating materials 5 and 6, and among these heat insulating materials, the heat insulating material 5 disposed between the bottom of the inner wall 3A is formed in a core shape, and is formed on the outer surface. The heat insulating materials 6 to be arranged are arranged in layers. It is preferable that the outer surface of the heat insulating material 6 located on the outer surface is further covered with an outer panel (not shown) or the like so as to bring about a cosmetic effect.

Since the present embodiment has the above configuration,
When the heating source 4 is ignited, the flame comes into contact with the bottom of the oil tank 2 so that the temperature of the oil tank 2 rises and the oil temperature rises. When the burner is used, the temperature of the heating source 4 increases when the combustion is continued. The heat of the heating source 4 itself tends to be transmitted to the casing 3, but the outer wall 3B of the casing 3
The heat transfer to the outer wall 3B is shut off because it is supported via the heat insulating material 5 with respect to the inner wall 3A having For this reason, the outer wall 3B of the casing 3 does not conduct heat transfer, thereby preventing a temperature rise and maintaining a state in which the outer wall 3B does not overheat.

On the other hand, the inner wall 3A and the outer wall 3B of the casing 3
A space for interposing a heat insulating material 5 is formed between the outer wall 3 and the outer wall 3 in which the air existing in this space is heated by the heating source 4 to increase the temperature, and the heated air is in contact therewith.
The temperature of B may rise. However, in this embodiment, since the heat insulating material 6 is disposed on the outer surface of the outer wall 3B, a contact portion between the outer wall 3B and the outside air is eliminated. Accordingly, heat radiation from the outer wall 3B is suppressed, so that heat from the heating source 4 is prevented from being taken away by the heat radiation. Therefore, since the heat from the heating source 4 does not cause heat loss due to heat radiation, it is consumed for heating the oil tank 2,
The temperature of the oil tank 2 is efficiently raised.

[0013]

As is apparent from the above embodiment, according to the first aspect of the present invention, the heating source is in a state of non-contact with the casing, and furthermore, the heat insulating material is disposed on the supporting portion. Therefore, heat transfer from the heating source to the casing is not performed. As a result, a rise in the temperature of the casing is suppressed, and it is possible to avoid a danger in a case where a human hand touches the casing. In addition, since heat is not transmitted to the outer wall, heat dissipation at the outer wall is also suppressed, so that heat loss is suppressed.

According to the second aspect of the present invention, since the heat insulating material is disposed on the outer surface of the casing, the heat radiation of the casing due to the contact between the outer surface and the outside air is suppressed. Thereby, heat loss due to heat radiation is prevented, so that the temperature of the liquid tank can be increased without lowering the heating efficiency from the heating source.
