DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a main casing, a burner, and a heat storage material arranged to surround a combustion portion of the burner and storing heat of combustion exhaust gas of the burner.
A combustion cylinder disposed outside the heat storage material, a blower that sucks and blows room air, and sends a part of the airflow to the burner, and the room air sucked by the blower and the combustion exhaust gas of the burner. A mixing section to be mixed, a hot air outlet from which the hot air produced by the mixing section blows, a burning time storage means for storing the burning time of the burner, and a length of the burning time stored in the burning time storage means. Heat storage heating time determining means for determining the length of heat storage heating time for heating only the heat storage material after stopping the combustion of the burner as a heat source, and heating only the heat storage material after the burner stops as a heat source in proportion to A control unit for controlling the output of the blower according to the length of the heat storage heating time based on the heat storage heating time determination means in the heat storage heating mode.

[0008] Since the temperature of the heat storage material rises in proportion to the length of time the burner burns, the amount of heat stored in the heat storage material is also proportional to the burner combustion time. The combustion time storage means stores the combustion time, the thermal storage heating determining means sets the thermal storage heating time in the thermal storage heating mode in proportion to the burner combustion time, and the control unit controls the thermal storage heating based on the thermal storage heating determination means in the thermal storage heating mode. After the time has elapsed, stop the blower. Even without providing a temperature detecting means in the heat storage material or the hot air outlet, the time for stopping the blower can be adjusted according to the amount of heat stored in the heat storage material, and comfortable heating can be performed without a feeling of cool air.

The heat-storage / heating-time determining means makes the length of the heat-storage / heating time proportional to the length of the combustion time. If the combustion time exceeds a certain time, the heat-storage / heating time is determined to be a certain value. Is set for the heat storage heating time.

[0010] The temperature of the heat storage material rises in proportion to the length of time the burner burns, but after a certain time, the temperature no longer rises. Therefore, the heat storage time determination means makes the length of the heat storage heating time proportional to the length of the combustion time, but if the combustion time exceeds a certain time, the length of the heat storage heating time is set to a certain heat storage heating time Therefore, the optimum heat storage heating time according to the heat storage amount can be obtained without providing the temperature detecting means in the heat storage material, the hot air outlet, or the like.

The heat storage heating time determining means sets the length of the heat storage heating time in proportion to the burner combustion amount and the integral value of the combustion time.

Since the burner combustion amount and the integral value of the combustion time have a high correlation with the heat storage amount of the heat storage material, the length of the heat storage heating time can be set accurately.

[0013] The heat storage heating time determining means makes the length of the heat storage heating time proportional to the burner combustion amount and the integral value of the combustion time. If the value exceeds a certain value, the heat storage heating time is determined. Is set to a certain heat storage heating time.

The amount of heat stored in the heat storage material is proportional to the burned amount of the burner and the integral value of the burning time. However, when the time exceeds a certain time, it does not increase any more. It can be set to a long heat storage heating time.

[0015] The heat storage heating time determining means sets the length of the heat storage heating time in proportion to the total time of all the combustion operation times performed from the start time of the heat storage heating mode to a predetermined time before. .

In the thermal storage heating mode, when the combustion heating by the burner is started while the heat amount of the thermal storage material is still remaining, and thereafter the mode is again shifted to the thermal storage heating mode, the combustion time of the burner in the immediately preceding operation is short. It can happen that the heat storage amount is large. Therefore, the heat storage heating time determination means sets the length of the heat storage heating time in proportion to not only the combustion time of the immediately preceding operation but also the total time of all the operation times performed from the start time of the heat storage heating mode to a certain time before. Therefore, a more accurate determination of the heat storage heating time can be performed.

Further, the heat storage heating time determining means is configured to make the heat storage heating proportional to the total value of the combustion amounts of all the burners and the integrated value of the combustion time during the operation performed from the start time of the heat storage heating mode to a predetermined time before. Set the length of time.

Then, in the heat storage heating mode, when the combustion heating by the burner is started while the heat amount of the heat storage material still remains, and thereafter the mode is shifted to the heat storage heating mode again, the combustion amount and the combustion time of the burner in the immediately preceding operation are determined. May be small, but the heat storage amount may be large. Therefore, the heat storage heating time determination means calculates not only the integrated value of the combustion amount and the combustion time of the burner in the immediately preceding operation, but also the total value of the integrated values of all the operation times performed up to a certain time before the start time of the heat storage heating mode. Since the length of the heat storage heating time is set in proportion, more accurate determination of the heat storage heating time can be performed.

Further, there is provided a remaining heat storage amount display means for calculating the heat storage amount of the heat storage material based on the integrated value of the burner combustion time and the combustion amount and sequentially displaying the calculated heat storage amount.

The user can know the amount of heat stored in the heat storage material at that time during the combustion heating by the burner or in the heat storage heating mode.

Also, a heat storage material provided to surround the main body casing, the burner, and a combustion portion of the burner and for storing heat of the combustion exhaust gas of the burner, and a combustion storage material provided outside the heat storage material. A cylinder, a blower that sucks and blows room air and sends a part of the airflow to the burner, a mixing unit that mixes room air sucked by the blower and combustion exhaust gas of the burner, A hot-air outlet from which the generated hot air is blown, hot-air detecting means for detecting a temperature of the hot air generated in the mixing section, room-temperature detecting means for detecting a room temperature, and the heat storage after the burner stops combustion. The heat storage heating time of the heat storage heating mode in which only the material is used as the heat source is proportional to the difference between the hot air temperature detected by the hot air detection means and the temperature detected by the room temperature detection means at the heat storage heating mode start time. Set is for a control unit for controlling the output of the blower by the length of the set heat storage heating time.

The amount of heat stored by the heat storage material at the start of the heat storage heating mode has a high correlation with the difference between the warm air temperature at the start of the heat storage heating mode and the room temperature, and the control unit makes the heat storage heating time proportional to the difference. By setting the length, more accurate heat storage heating time can be obtained, and comfortable and efficient heating can be performed. Also,
In a heat storage heating mode in which heating is performed using only the heat storage material after the burner stops combustion, a remaining time display means for sequentially displaying the remaining time until the heat storage heating mode ends is provided.

Then, the user can know the remaining time until the heat storage heating mode ends.
