[0029]

In the heat storage combustion heating apparatus of the present invention, in order to vaporize the liquid fuel in a state where the heat is not stored in the heat storage section, when the electric heater built in the vaporizer is energized, the vaporizer is heated and the temperature rises, When the temperature sensor that detects the temperature of the carburetor detects that the temperature has risen to the set temperature, oil and air are supplied from the oil supply pipe and the air nozzle, vaporize, and burn in the burner. On the other hand, in order to vaporize the heat storage part in the heat storage state, the heat storage part is fixedly installed so as to conduct heat to the carburetor, so the heat storage part heats the carburetor, while shortening the ignition time thereafter, Power consumption can be reduced. And without providing a control device for alternately controlling heat conduction and heat cutoff between the vaporizer and the heat storage device as in the conventional case, the heat of the heat storage device is used for heating the vaporizer, while shortening the ignition time. The power consumption can be reduced.

Next, since the heat transfer member for the heat storage section is also used as the heat storage material built in the heat storage section, when it is heated by the combustion heat of the burner, the temperature of the built-in heat storage material rises and the heat storage section stores heat. Stores heat by transferring heat to the material. Moreover, since they are the same member, heat can be efficiently transferred, and the heat of the heat storage device can be used to heat the vaporizer to shorten the ignition time and reduce the power consumption.

The unidirectional heat control section provided between the vaporizer and the heat storage section transfers heat only from the high temperature side to the low temperature side, and does not transfer heat from the low temperature side to the high temperature side. Therefore, it is heated by the combustion heat of the burner, the temperature of the built-in heat storage material becomes high, and the heat of the device is used to heat the carburetor, while shortening the ignition time,
Power consumption can be reduced. On the other hand, when the heat is not stored in the built-in heat storage material, the one-way heat control unit transfers heat to the heat storage unit even if the electric heater built in the carburetor is energized to heat the carburetor and raise the temperature. Since it does not, there is no delay in vaporization time.

Since the one-way heat control section is composed of a heat pipe, heat is transferred only from the high temperature side to the low temperature side, and conversely, heat is not transferred from the low temperature side to the high temperature side. Therefore, the heat of combustion of the burner heats the built-in heat storage material to a high temperature, and the heat of the device is used to heat the carburetor, so that the ignition time can be shortened and the power consumption can be reduced. On the other hand, when the heat is not stored in the built-in heat storage material, the one-way heat control unit transfers heat to the heat storage unit even if the electric heater built in the carburetor is energized to heat the carburetor and raise the temperature. Since it does not, there is no delay in vaporization time.

By providing the temperature-dependent expansion heat transfer part between the heat storage part and the vaporizer, expansion and contraction are carried out in proportion to the temperature rise, and the heat storage part and the vaporizer come into contact with each other at a certain temperature or higher to transfer heat. Therefore, the internal heat storage material is heated by the combustion heat of the burner, and the heat of the device is used for heating the carburetor, so that the ignition time can be shortened and the power consumption can be reduced.

Since the heat storage material contained in the heat storage section is a latent heat storage material, it melts and expands when heated to a high temperature, so that its liquid level rises and comes into contact with the vaporizer. Therefore, the carburetor is heated by the heat storage amount of the latent heat storage material, so that the power consumption can be reduced while shortening the ignition time. On the other hand, when the heat storage material has no heat storage capacity, it is a latent heat storage material, so when it is cooled and solidified, the volume shrinks, and the solid surface has a gap with the vaporizer, so when heating by energizing the electric heater of the vaporizer On the contrary, heat is not taken away by the heat storage section.

Since the heat storage unit driving device for moving the heat storage unit with respect to the vaporizer is provided, when the heat storage unit is in the heat storage state, the heat storage unit is brought into contact with the vaporizer to conduct heat from the heat storage unit to the vaporizer. Therefore, it is possible to reduce the power consumption while shortening the ignition time. On the other hand, when the heat storage section is not in the heat storage state, the heat is cut off by moving the heat storage section to the non-contact state with the carburetor, and when the electric heater of the carburetor is energized to heat, the heat is also deprived of heat to the heat storage section. It is something that has been done so.

Since the heat storage unit temperature sensor detects the temperature of the heat storage unit and determines whether or not the heat storage unit is in a heat storage state, when the temperature of the built-in heat storage body decreases, the burner is burned to bring the built-in heat storage material to a predetermined temperature. By constantly storing heat, heat is conducted from the heat storage unit to the carburetor, and it is possible to reduce power consumption while shortening the ignition time.

Since the heat storage burner for heating the heat storage unit from the vaporizer is provided, the heat storage unit temperature sensor detects the temperature of the heat storage unit and determines whether or not the heat storage unit is in the heat storage state.
When the temperature of the built-in heat storage body decreases, the heat storage burner is burned to keep the heat storage unit in the heat storage state at all times, so that the ignition time can be shortened and the power consumption can be reduced.

When the burner is burning, the combustion tube heat radiation prevention lid is driven so as to open the combustion tube to discharge the combustion gas from the combustion tube, and at the same time, heat is stored in the heat storage section. On the other hand, since the combustion cylinder is closed when the burner is not burning, the heat generated by heating the carburetor in the heat storage section is further radiated from the carburetor through the burner from the upper part of the combustion cylinder, but the combustion cylinder is closed. Therefore, the heat radiation is reduced, the heat storage unit can efficiently heat the carburetor, and the power consumption can be reduced while shortening the ignition time.
