Abstract

PURPOSE:To stabilize evaporation, to save electric power, and to increase durability in an evaporator, by exhausting exhaust gas out of a combustion apparatus from the top of a burner body, by forming a passage for exhaust gas around the bottom of an evaporator, and nearly in the center parts of an evaporator and a burner body in order. CONSTITUTION:Combustion exhaust gas, going through between the outer side of an evaporator 15 and the inside of an outer cylinder 19 from between a burner body 28 and an outer plate 29, and via passages 20 and 21 being formed around the outer side of an evaporator 15, is exhausted from an exhaust gas outlet 32 at the top of a burner body. In the course of the flow of combustion exhaust gas, the side wall, the bottom, and the center part of an evaporator 15 are sufficiently heated by the exhaust gas, so that fuel can continuously be evaporated only by the feedback of combustion heat, through power supply to an electric heater 16 is cut off. The evaporator can receive heat from almost all the surface area of an evaporator body during stationary combustion, so that it can be kept in high and uniform temperature without being deformed by ununiform degree of thermal expansion, and its durability can be increased. The power supply to an electric heater can be cut off immediately after combustion is started, as the evaporator is heated by exhaust gas which reaches the bottom of an evaporator body as soon as combustion is started. As a result, power can be saved and stabilized evaporation can be performed in the evaporator.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a combustion device mainly used in household heating equipment and the like.

Conventional configuration and its problems A typical example of a conventional combustion device is shown in FIG.

In FIG. 1, 1 is a vaporized body, which is heated by an electric heater 2. Reference numeral 3 indicates a mixing plate, 4 indicates a flame hole body having a large number of slits, and 5 indicates a flame in premix combustion. 6 is the outer cylinder,
7 is a primary air blast pipe, 8 is a pipe, and 9 is a fuel pump. 10 is a secondary air blower pipe, and 11 is a blower. 12
is a cylinder that guides the exhaust gas to the upper FSIS, and a purification probe 13 having 14 small holes is installed at the upper end of the cylinder.

In this type of combustion device, fuel fi1. It hits the side wall of the vaporized body 1 facing the vibrator 8 and flows to the bottom, where it is vaporized.

While the combustion is still in steady state, the vaporized body 1 is heated by heat conduction from the flame hole body 4 to the vaporized body 1 and a part of the flame 5 is applied to the second part of the vaporized body 1, and the heat is transferred to the electric heater 2. city, trying to minimize it as much as possible.

However, as can be seen from FIG. 1, it is safe to receive heat from the flame 5 and the flame hole body 4 at the tip of the vaporizer 1, and to conduct the heat to the bottom through the 4111 wall.

The tip of the vaporized body 1 and There is no choice but to create a large temperature difference at the bottom. These factors tend to cause deformation and quality deterioration due to non-uniform expansion.

In addition, even though most of the liquid fuel is vaporized at the bottom, the vaporized body 1 has the lowest temperature of t7A degrees, a stable vaporization state is obtained, and there is also a lot of t' and tar generation.

Furthermore, the bottom of the vaporized body 1, FylS, was kept at a constant temperature at a constant temperature./Kome'yama;;! To Beata 2 on 11th 'iu City 1
11i) it? -1 It is necessary to use it, but it costs a lot of money; it requires a lot of power and there is also a problem with the economy when using it.

1j of the invention In the conventional method according to the present invention; however, it is not intended to eliminate the A force of 11φ! is applied to achieve stable vaporization without tar generation and labor savings, and the entire vaporized body is uniformly heated.

The exhaust gas is discharged from the combustion device to the outside of the combustion device. Due to this +14 formation, the combustion gas comes into contact with the outer periphery, bottom, and center of the vaporized body, and the heat necessary for vaporization can be effectively fed back. The entire vaporized material can be maintained at a uniform ri++'+ degree that is optimal for vaporization.
