The control unit controls the blower 28 and the high-temperature gas switching unit 33 in a predetermined sequence based on the sequence.

In the above configuration, when the switching means 32 switches the airflow from the blowing means 29 to the radiating means cooling air passage 26 side, the radiant heating operation is performed, and the entrance of the radiating means cooling air passage 26 is opened. The air flow from 29 flows to the radiating means cooling air passage 26, and the flue gas generated in the combustion part 21 flows upwardly of the combustion tube 22 due to the force flowing downward, and is further raised by the heat-induced draft.

When the automatic switching button 39 is pressed to start the operation in which the automatic operation mode switching is selected, the temperature detecting means 4 of the device is set based on the set temperature set by the operation section 36.
The difference obtained by subtracting the temperature detected in Step 2 is equal to or less than a predetermined value. For example, when the heating load is low with a temperature setting difference of 2 ° C. such that the user does not feel so cold and wants heating, that is, in the early spring when the temperature is not so cold and slightly chilly. In the early autumn or early autumn, the airflow due to the warm air gives the user discomfort, but since the above-mentioned radiant heating operation is performed from the start of operation, heating is started without feeling discomfort. become. Also, if the difference is higher than the predetermined value of the heating load is high, that is, if you want to warm up early in the morning, such as a severely cold morning, the warm air heating operation is performed at the start of operation, The user can heat up quickly and the room temperature rises quickly. In other words, the heating operation start mode is automatically switched between the radiant heating operation and the hot air heating operation without the user's consciousness, thereby increasing the usability of the user and preventing the user from operating by mistake. Can be improved.

FIG. 5 is a flowchart showing another example of the automatic operation mode.

In FIG. 5, when the automatic switching button 39 is pressed to start the operation in which the automatic operation mode switching means is selected, the warm air heating operation is performed in step 53, and after a predetermined time, the radiant heating operation is switched to step 54. There is a switching configuration.

Then, when the automatic switching button 39 is pressed and the automatic operation mode switching means is selected and the operation is started, the warm air heating operation is performed at the beginning of step 53. As soon as the room temperature rises to a certain extent, since the temperature can be quickly increased, the room temperature of the entire room rises uniformly and quickly, and the operation is switched to the radiant heating operation in step 54 after a predetermined time. The radiant heating operation does not cause a sense of airflow due to the wind, and the user does not feel discomfort due to the warm air. That is, when the heating operation is started without the user's awareness, the warm air heating operation is performed first to warm the entire room quickly, and then the operation is switched to the radiant heating operation and automatically shifted to comfortable heating, and the operation is started. User convenience increases,
The user does not operate by mistake, and the feeling of heating can be improved.

FIG. 6 is a flowchart showing another example of the automatic operation mode.

In FIG. 6, when the automatic switching button 39 is pressed to start the operation in which the automatic operation mode switching is selected,
In step 55, the above-described hot air heating operation is performed, and when the temperature detected by the temperature detecting means of the device reaches a predetermined temperature, the operation is switched to the radiation heating operation in step 56.

The same effect as in the automatic operation mode shown in FIG. 5 is obtained. When the automatic operation button 39 is pressed to start the operation in which the automatic operation mode switching is selected, the heating operation is performed without the user's awareness. At the start of the operation, the warm air heating operation is first performed in step 55 to quickly warm the entire room, and then the operation is switched to the radiant heating operation in step 56 to automatically shift to comfortable heating, thereby increasing the usability of the user. In addition, the user does not operate by mistake, and the feeling of heating can be improved.

When the temperature detected by the temperature detecting means 42 of the device reaches a predetermined temperature, switching from the hot air heating operation to the radiant heating operation is performed.

FIG. 7 is a flowchart showing another example of the automatic operation mode.

In FIG. 7, the amount of combustion of the device is indicated by the operation unit 3.
According to the difference between the set temperature set in step 6 and the temperature detected by the temperature detecting means 42 of the device, the combustion amount of the device is switched in step 57, and the automatic switching button 39 is pressed to switch the automatic operation mode switching device. In the heating operation selected, when the switched combustion amount of the device is equal to or less than a predetermined amount, the above-described radiant heating operation is performed in step 58, and until then, the hot air heating operation is performed.

Then, in accordance with the difference between the set temperature set by the operation section 36 and the temperature detected by the temperature detecting means 42 of the device, the combustion amount of the device is switched at step 57. Therefore, the heating can be performed with the heating capacity according to the heating load, the room temperature can be finely adjusted, and the device is switched during the heating operation in which the automatic switching button 39 is pressed and the automatic operation mode switching unit is selected. Since the radiant heating operation is performed in step 58 when the combustion amount is equal to or less than the predetermined amount, similarly to the effect of the automatic operation mode shown in FIG. 6, the room temperature rises to the predetermined temperature and the heating load increases. Before it becomes smaller and the heating by the warm air of the hot air heating operation is uncomfortable, it is possible to switch to the radiant heating operation, and further, the usability of the user increases, Improvement of the sense of humor is to be achieved.

FIG. 8 is a flowchart showing another example of the automatic operation mode.

In FIG. 8, when the automatic switching button 39 is pressed and the automatic operation mode switching means is selected, heating is performed.
Usually, the above-described radiant heating operation is performed, and the above-described warm air heating operation is intermittently performed at step 59 every predetermined time.

When the automatic switching button 39 is pressed and the automatic operation mode switching means is selected for heating, the radiant heating operation is normally performed without performing the hot air heating operation.
If the user does not feel the discomfort of heating due to the hot air, and if the radiant heating operation is continued, the room temperature of the room will be uneven, and the upper part of the room will be hot, and the lower part of the floor will be cold, and the user will experience discomfort due to the temperature difference. However, since the above-described warm air heating operation is intermittently performed at step 59 every predetermined time, the air in the room is stirred by the warm air of the warm air heating operation, and The drawback that the temperature becomes uniform and the unevenness of the room temperature of the room only for the radiant heating operation is compensated for, and further, the usability of the user increases,
The feeling of heating can be improved.

FIG. 9 is a flowchart showing another example of the automatic operation mode.

In FIG. 9, during the radiant heating operation, the flow rate adjusting means 30 periodically swings the air flow from the blowing means 29 when a predetermined time has elapsed, and in step 61 when the predetermined time has elapsed, weakens the air flow. There is.

During the radiant heating operation, the flow rate adjusting means 30 periodically shakes the air flow from the air blowing means 29 when the predetermined time has elapsed, and makes the air flow weak at step 61 when the predetermined time has elapsed. Because there is
The circulating flow of the air in the room formed by being discharged upward and forward of the device through the radiating means cooling air passage 26 periodically fluctuates, and the circulating flow becomes a nodular flow and reaches far. As a result, the circulating flow spreads throughout the room, increasing the uniformity of the temperature of the room, reducing the circulating flow, further eliminating the feeling of airflow, and improving the feeling of heating become able to.

At the same time, a part of the airflow from the blowing means 29 is taken in from the cooling opening 34 of the double cooling air passage 33 having a space provided on the outer wall of the combustion tube 22, The cooling outlet 3 of the connecting cooling air passage 33
5 and is taken into the combustion cylinder 22 so as to be mixed with the combustion exhaust gas which becomes a high-temperature gas, so that the air flow from the blowing means 29 is periodically increased or decreased by the flow rate adjusting means 30. When this occurs, the amount of radiation energy generated from the radiator 23 also fluctuates.

That is, since the amount of radiant energy generated from the radiator 23 is made to fluctuate depending on the intensity, the user receives a change in the amount of radiant energy generated from the radiator 23 and is conscious of the feeling of heating. Therefore, the comfort of the heating sensation due to the radiation of the user is increased, and at the same time, the average heating capacity can be gradually reduced slightly without the user feeling uncomfortable, and energy saving can be achieved.

In the above embodiment, the circulating air supply means is described as using the air supply means 29 for supplying an air flow which is mixed with the high-temperature gas from the high-temperature gas generation means and discharged as hot air. Structure and radiator 2
Although the configuration in which the amount of radiant energy generated from 3 is fluctuated with the intensity is described at the same time, this may be separately provided by another blowing means, and the configuration of each component may be any configuration as long as the object of the present invention is achieved. Such a thing may be used.
