Is discharged to the upper front of the device housing 27, so that there is only a sense of airflow above the device, and there is no airflow in front of the device, that is, the user's living space, and discomfort due to airflow is used. The feeling of heating can be improved without the user feeling.

Further, since the control means 37 has the manual operation mode switching means 39, the radiant heating operation and the hot air heating operation can be easily switched by the manual operation mode switching means 39. Can easily switch between the radiant heating operation and the hot air heating operation by operating the manual operation switching button 33 while checking the manual operation display means (LED) 34 according to the use environment, thereby increasing the usability of the user. And a feeling of heating can be improved.

Further, since the control means 37 has the automatic operation mode switching means 40, the user can automatically switch between the radiant heating operation and the hot air heating operation based on the conditions set in advance by the user. In other words, the user does not need to be aware of switching between the radiant heating operation and the hot air heating operation, and the user does not have to worry about making a mistake in the switching timing, so that the usability and the feeling of heating can be further improved. In other words, without the user's awareness, at the beginning of the heating operation, the warm air heating operation is performed first to warm the entire room quickly, then switched to the radiant heating operation and automatically switched to comfortable heating and used This improves the usability of the user, and prevents the user from operating by mistake, thereby improving the feeling of heating.

Further, during the radiant heating operation, the heating surface 25 of the radiator 23 is heated to a high temperature by the high-temperature combustion gas, and the high-temperature radiator 23 generates the collected heat as radiant energy. When the heating capacity is minimized, the generated radiant energy is small and the user can feel the amount sufficiently.When the heating capacity is maximized, the generated radiant energy is too large, and There is a concern that the radiation may be heated or uncomfortable, and that the temperature of the radiator 23 may be too high to cause a sense of danger. However, in the present embodiment, since the heating capacity during the radiant heating operation is smaller than the heating capacity during the hot air heating operation, the maximum heating capacity of the indoor heating can be secured during the hot air heating operation. . That is, when the heating load at the start of the operation is large, the hot air heating operation is performed, and when the indoor temperature rises and enters the stable region and the heating load is reduced, the radiant heating operation can be performed. It is possible to increase the usability of the user and to improve the feeling of heating.

Further, the amount of combustion of the device is determined by operating means 3
Since the combustion amount of the device is switched according to the temperature difference between the set temperature set in step 2 and the temperature detected by the temperature detecting means 38 of the device, heating can be performed with a heating capacity corresponding to the heating load. At the same time that the room temperature can be finely adjusted and the automatic operation mode switching means 40 is selected for heating,
When the switched heating capacity of the device is equal to or less than a predetermined amount, the above-described radiant heating operation is performed, and until then, the warm air heating operation is performed, so that the room temperature rises to the predetermined temperature and the heating load increases. It becomes possible to switch to the radiant heating operation before the heating by the warm air of the warm air heating operation becomes uncomfortable and it becomes possible to increase the usability of the user and to improve the feeling of heating. it can.

During the warm air heating operation, warm air is supplied to the equipment housing 2.
7, the user feels a feeling of heating due to the warm air in the user's living space, but at the start of the radiant heating operation, it takes time for the user to sufficiently increase the temperature of the radiator 23 for obtaining the radiant feeling. In short, during the radiant heating operation, the user does not feel the feeling of heating, so that the user may feel a little cold when switching during the radiant heating operation. However, in this embodiment, the heating capacity at the time of switching is slightly higher than the heating capacity at the time of radiant heating operation at the time of the hot air heating operation. The switching can be performed without impairing the feeling of heating, and the usability can be improved.

(Embodiment 2) FIG. 4 is a flowchart of a heating apparatus according to an embodiment corresponding to the fifth aspect of the present invention. In the present invention, since the configuration of the control means is different from that of the first embodiment, the same reference numerals are given to the portions having the same configuration and the operation and effect with reference to FIGS. The explanation will be focused on the process.

The control means 37 constitutes a control flow shown in FIG. 4, and determines the heating capacity of the equipment by comparing the temperature difference between the set temperature set by the operation means 32 and the room temperature detected by the temperature detection means 38 of the equipment. The automatic operation mode switching means 40a for switching the heating capacity of the appliance in accordance with the operation mode switching means 37a.
When the selected heating is performed, the above-described radiant heating operation is performed when the switched heating capacity of the device is equal to or less than a predetermined amount, the hot air heating operation is performed until then, and the switching between the radiant heating operation and the hot air heating operation is performed. Is performed when the temperature difference between the room temperature and the set temperature has continued for a predetermined time.

In the above embodiment, when the apparatus is operated, the operation and the effect are exhibited in the same manner as described in the first embodiment.

After checking and confirming whether or not the hot air heating operation is started in S3. Then, the warm air heating is performed, and if it is checked in S4 whether the indoor heating capacity is equal to or less than a predetermined amount, the operation is switched to the radiant heating operation in S5. Subsequently, it is checked in S6 whether the above-mentioned temperature difference is equal to or more than a predetermined value, and then, in S7, it is confirmed whether the above-mentioned temperature difference has passed for a predetermined time.

As described above, the effect of the automatic operation mode described in the first embodiment is obtained, and the temperature detected by the temperature detecting means 38 of the device changes abruptly to switch from the radiant heating operation to the hot air heating operation. Instead, the user may receive warm air and feel the discomfort. However, in the present embodiment, the switching between the radiant heating operation and the hot air heating operation is performed in S8 when the temperature difference between the room temperature and the set temperature has continued for a predetermined period of time. Switching is not performed due to the temperature change, and the radiation heating operation can be continued without impairing the user's feeling of heating. For example, when the device is arranged near the entrance of the room, and when the user goes in and out and opens and closes the door, the ambient temperature of the temperature detecting means 38 of the device suddenly decreases locally, Although the temperature has not changed much, the temperature detected by the temperature detecting means 38 of the device temporarily decreases, and the user switches from the stable radiant heating operation located in front of the device to the hot air heating operation. There is a concern that the user may switch suddenly and feel uncomfortable with the hot air heating when the user receives the warm air.
When the temperature detected returns to the previous temperature by opening and closing the door of the room, the radiant heating operation is continued, and the temperature does not return to the previous temperature even if the temperature detected by the temperature detecting means 38 of the device is long. In the case, it will be switched to hot air heating operation,
It is very convenient to switch between hot air and radiant heating operation without impairing the user's feeling of heating.

The malfunction of switching from the heating operation to the hot air heating operation can be further reduced. In other words, when the device is arranged near the entrance of the room and the ambient temperature of the temperature detecting means 38 of the device drops sharply locally when the user enters and exits and opens and closes the door, the entire room temperature Although the temperature has not changed much, the temperature detected by the temperature detecting means 38 of the device temporarily drops, and the user switches from the stable radiant heating operation to the hot air heating operation which is located in front of the device. Then, the user may receive the hot air and feel uncomfortable with the hot air heating. However, when the temperature difference between the room temperature and the set temperature is equal to or less than the first predetermined value, the radiant heating operation is continued. Further, even when the temperature difference between the room temperature and the set temperature is equal to or greater than the first predetermined value, when the change gradient is equal to or greater than the second predetermined value, that is, in a short time, the temperature detected by the temperature detecting means 38 of the device is the room temperature. If the door is opened and closed and the temperature returns to the previous temperature, the radiant heating operation is continued. If the temperature detected by the temperature detecting means 38 of the device does not return to the previous temperature for a long time, the hot air heating operation is performed. , And the switching between the hot air and the radiant heating operation can be made very convenient without deteriorating the user's feeling of heating.
