Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for improving thermal efficiency by being used for a device for heating by burning gas or oil such as a gas stove, a gas range, a gas bath, and an oil bath.

[0002]

[Prior Art]

 In gas stoves, gas stoves, baths, etc. that use gas or petroleum (including kerosene and heavy oil) as fuel, basically the temperature of the flame of gas or petroleum is the heat exchange of cooking utensils such as pans and frying pans, or the bath cooker. It is transmitted to the bottom or surface of the cooking pipe or used for directly heating the food.

Of the calories of gas, the calories that contribute to heating cooking utensils and food items are not large. That is, heat escapes. In order to increase efficiency, various proposals have been made to place far-infrared rays by placing a ceramic instrument on or around a gas heat source (Actual Publication No. 1-222122, Exploratory Publication No. 1-148509). (See gazette, etc.).

[0004]

[Problems to be solved by the device]

 Another object of the present invention is to convert a part of the combustion energy into infrared rays or far infrared rays to significantly improve the thermal efficiency of the object to be heated.

[0005]

[Means for Solving the Problems]

 In order to solve this problem, a heat radiator for a heating device according to the present invention comprises a heat-resistant seat placed around a heat source of the heating device, a ceramic ring installed on the seat, and the ring. And a coil-shaped metal wire made of a heat-resistant metal that is installed so as to surround the flame.

[0006]

[Operation] The heat of combustion of gas or oil is transferred to the ceramic ring and converted into infrared rays and far infrared rays, and the coiled metal wire also acts as a radiator of infrared rays and far infrared rays. Since the surface area of the coiled metal wire is large relative to the volume of the conductor, the heat wire is effectively radiated. The heat-resistant seat prevents the heat rays radiated from the back surface of the ceramic ring from heating the gas appliances such as the stove and stove wastefully, leading to high temperatures and oxidation (rust).

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view showing a state of being set in a gas appliance. In FIG. 1, reference numeral 1 denotes a hollow bowl-shaped seat, which is made of a heat-resistant material such as stainless steel. Reference numeral 2 denotes a ring made of ceramics, for example, unglazed, which is formed in a hollow bowl shape like the seat 1 and is placed on the seat 1. This may be split. 3 is a heat-resistant metal, for example, a coiled metal wire made of nichrome wire, which is set on the ring 2. In addition, legs 1a are provided at the bottom of the seat 1 to form a gap with the gas appliance. In FIG. 2, 4 is a gas appliance, 5 is a burner, and 6 is a pan receiver. The heat radiator of the present invention is set in the gas instrument 4 so as to surround the burner 5 which is a heat source.

When the gas is ignited and the pan or the like is placed on the pan receiver 6, the pan or the like is primarily heated by the flame of the gas, but the temperature around the flame rises. The metal wire 3 is also heated. As a result, infrared rays and far infrared rays are emitted, and the pot etc. is secondarily heated. Therefore, the thermal efficiency is increased. Since the ring 2 is placed on the seat 1 and the gas appliance side is covered by the seat 1, heat radiation to the gas appliance side is suppressed and the gas appliance main body is rarely heated.

The heat radiator of the present invention may be arranged around the burner in a bath kettle such as a gas bath or an oil bath.

[0010]

[Effect of the device]

 As described above, according to the present invention, in addition to the infrared and far infrared radiation effects of the ceramic ring, the infrared and far infrared radiation effects of heating the coiled metal wire are superimposed, and no heat source is added. Without increasing the thermal efficiency. Therefore, it is possible to reduce the amount of fuel used and save resources.
