Reference numeral 26 denotes a radiator heating air passage 24 and the equipment housing 2.
7 during the radiant heating operation.
In the radiating means cooling air path for reducing heat conduction to the radiating means cooling air path 26, the air flow flowing through the radiating means cooling air path 26 is discharged upward and forward of the device to form a circulating flow of air in the room.

Reference numeral 28 denotes a hot air outlet located below the radiating means cooling air passage 26 and disposed below the radiator 23. The exhaust gas generated by the combustion section 21 and the indoor air flow are mixed and discharged as hot air. It has become.

Numeral 29 is a blower for supplying room air as an air flow, and has a flow control means 30 for adjusting the flow rate of the air flow during the radiant heating operation. Via the switching means 32, it is switched to the radiating means cooling air passage 26 side or the hot air outlet 28 side and flows.

A part of the air flow 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 and having a double structure.
The combustion tube 22 is discharged into the combustion tube 22 through the cooling outlet 35 of the connected cooling air passage 33 and mixed with the high-temperature gas.
It can be taken inside. These 33 to 35 form high-temperature gas air supply means.

Reference numeral 36 denotes an operation unit for setting the operating conditions of the device. A manual switching button 37 for switching the high-temperature gas from the high-temperature gas generating unit to the radiator side or the hot air outlet side by the switching unit 32 and a manual radiation button 37 Manual display function (LED) 3 that indicates switching between heating operation and hot air heating operation
And a manual operation mode switching means comprising:
An automatic switching button 39 for automatically switching between the radiant heating operation and the hot air heating operation based on a preset condition, and an automatic display function (LED) for displaying automatically switching between the radiant heating operation and the hot air heating operation It has an automatic operation mode switching button 40.

Reference numeral 41 denotes a control unit which is disposed in the suction port of the blowing means 29 and detects the room temperature as a representative temperature of the room by the equipment. The control unit controls the blower 29 and the high-temperature gas switching unit 32 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. 29 flows into the radiating means cooling air passage 26, and the combustion exhaust gas generated in the combustion part 21 loses its downward flowing force.
, And flows further upward due to the draft by the heat, and is guided to the radiator heating air passage 24.

Then, the heat collecting surface 25 of the radiator 23 is heated to a high temperature by the high-temperature flue gas generated in the combustion section 21, and the heat collected by the heat collecting surface 25 is generated as radiant energy from the radiator 23, You will be able to heat it. At the same time, the air flow that has flowed into the radiating means cooling air passage 26 is discharged as warm air to the front and upper part of the device to form a circulating flow of room air. The air in the entire room is mixed, and the temperature of the entire room is substantially uniform as compared with the case of heating using only radiation.

Further, since the circulating flow is also discharged to above the device, only a sense of airflow above the device can be obtained.

The switching means 32 is controlled in a predetermined sequence.

Here, the high-temperature gas generating means has a combustion section 21 for burning fuel, and is configured to generate high-temperature gas using the combustion gas. As compared with those using a heat source or another heat source, a large amount of heat can be obtained and a high-temperature gas having a high temperature level can be easily obtained.

That is, in the hot air heating operation, the heating capacity for warming the entire room can be supplemented by the amount of combustion in the combustion section.
In the radiant heating operation, a high-temperature gas having a high temperature level can be obtained, so that the heat collected by the heat-collecting surface 25 heated by the high-temperature gas can be generated from the radiator 25 as large radiant energy. .

Further, since there is provided the flow rate adjusting means 30 for adjusting the flow rate of the air flow of the air blowing means 29 during the radiant heating operation, a part of the air flow from the air blowing means 29 is mixed with the combustion exhaust gas which becomes high temperature gas. So that the temperature of the combustion exhaust gas decreases when the air flow is large,
The heat collection on the heat collecting surface 25 of the radiator 23 becomes worse, and the radiator 2
5 reduces the amount of radiant energy generated. Also, when the airflow from the blowing means 29 decreases,
The temperature of the flue gas rises, and the heat collecting surface 25 of the radiator 23 is increased.
And the amount of radiant energy generated from the radiator 23 increases.

That is, when the flow rate of the air flow of the blowing means 29 is increased or decreased, the temperature of the combustion exhaust gas changes due to the low-temperature air flow mixed with the combustion exhaust gas, and the temperature of the heat collecting surface 2 of the radiator 23 is increased.
As a result, the amount of radiation energy generated from the radiator 23 changes, and the radiator 2
By varying the amount of radiant energy generated from 3, the user's feeling of heating can be improved.

Further, the switching section 32 controls the combustion section 2.

Since the user has a manual operation mode switching means, the user can easily switch the radiant heating operation and the hot air heating operation with the manual operation mode switching means, and the user can change the operation according to the use environment. By operating the manual switching button 37 while checking the manual display function (LED) 38, it is possible to easily switch between the radiant heating operation and the hot air heating operation, thereby increasing the usability of the user and improving the feeling of heating. Can be achieved.

Further, an automatic switching button 39 for automatically switching between the radiant heating operation and the hot air heating operation based on a preset condition and a display indicating that the radiant heating operation or the hot air heating operation is automatically switched. Automatic display function (LED)

Since there is no need to be conscious of switching between the operation and the hot air heating operation, and there is no fear that the user may make a mistake in the switching timing, the usability of the user is further increased and the feeling of heating can be improved.

FIG. 4 is a flowchart showing a first embodiment of the automatic operation mode.

In FIG. 4, when the automatic switching button 39 is pressed to start the operation in which the automatic operation mode switching means is selected,
When the difference obtained by subtracting the temperature detected by the temperature detecting means 42 of the device from the set temperature set by the operation unit 36 is equal to or less than a predetermined value, the radiant heating operation is performed in step 51, and the subtracted difference becomes the predetermined value. Is exceeded, the above-described warm air heating operation is performed in step 52.

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 obtained from the set temperature set by the operation unit 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 embodiment 2 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 above-described warm air heating operation is performed in step 53, and after a predetermined time, the radiant heating operation is performed in step 54. There is a switching configuration.

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 at the beginning of step 53. As soon as the room temperature rises to a certain extent, the room temperature of the whole room rises uniformly and quickly, and the operation switches to the radiant heating operation in step 54 after a predetermined period of 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 embodiment 3 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 user is unaware of the heating operation. 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.

Further, 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. Before the heating by the hot air of the wind heating operation feels uncomfortable, it becomes possible to switch to the radiant heating operation, and further, the convenience of the user increases,

FIG. 7 is a flowchart showing another reference example 4 of the automatic operation mode.

In FIG. 7, the operating amount of the device
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 unit 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 described above is performed in step 58 when the combustion amount is equal to or less than the predetermined amount, the room temperature rises to the predetermined temperature and the heating load increases, similarly to the effect of the automatic operation mode shown in FIG. 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 reference example 5 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 above-described 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 an example of the automatic operation mode of the present invention.

In FIG. 9, during the radiant heating operation, the flow rate adjusting means 30 periodically shakes the air flow from the blower means 29 when the predetermined time elapses, and makes it strong at step 60 when the predetermined time elapses. There is.

Then, 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 elapses, at step 60, and weakens at step 61 when the predetermined time elapses. 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 air 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 cylinder 22, Cooling outlet 3 of connected 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 caused by the radiation of the user is increased, and at the same time, the user can gradually decrease the average heating capacity without feeling uncomfortable, thereby achieving energy saving.

In the above embodiment, the circulating air blowing means is described as using the air blowing means 29 for supplying an air flow which is mixed with the high-temperature gas from the high-temperature gas generating 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.
