1. Problems to be solved by the invention - 1 - Conventional example of 1 tree, 1 fork, height 11 heat Fy] Machine'e IJ,, Heating with hot air and J, Ru to floor 1 and D'r Heating was always carried out by the same station, and there was no master-slave relationship between the two1, and the strength of heating operation was determined by the combustion equipment (
2) The heat exchanger (5)-C was adjusted to the height of the wet polishing of hot water using the heated blade, and the rotational speed of the convection cylinder (23) was adjusted to avoid increasing or decreasing. However, when running J3 in strong heating mode, the temperature is 1! lil Danigawa heat exchanger (18) and floor heating panel for floor heating (19)
) was circulating relatively high temperature water.

Furthermore, during the heating operation in the weak heating mode d3, low-temperature hot water was being circulated through the heat exchanger (1B) and the floor heating panel (19). Therefore, when increasing the amount of hot air (J
When increasing the rotational speed of the convection fan (23) and decreasing the humid air i〒1, the rotational speed of the convection fan (23) was decreased.

However, heating using warm air usually requires hot water at a higher temperature than heating using floor heating. Therefore, even if the heating condition is just the right temperature for floor heating, if you use hot air for heat exchange, it will be cold. There were times when I felt @. For this reason, when it is desired to emphasize hot air heating, it is necessary to avoid circulating high-temperature hot water. On the other hand, floor heating did not use very high-temperature hot water and was able to provide sufficient heating similar to the high-temperature mode.

However, with conventional hot air heaters with floor heating, even when you place emphasis on hot air heating and want to increase the hot air i%, the hot water is circulating at a low temperature, making it difficult to function as a hot air heater. There was something that Song couldn't do. In addition, if floor heating is used to raise the temperature of the floor, relatively high-temperature hot water may be circulating even when the floor is not warm, which may be wasteful in terms of heating efficiency.

For this reason, it has been desired to have heating operation that is appropriate and suitable for hot air heating and floor heating.

Therefore, the present invention can switch the operation mode between heating operation with warm air-1 integrated heating operation and heating operation mainly with floor heating, and each operation
The object of the present invention is to provide a warm air heater with floor heating that is capable of providing appropriate and efficient heating according to the environment.

[Means for solving the problem - 1 The floor heating (=J hot air heater) according to the present invention is a heat exchanger for generating hot air by converting hot water heated by the heat exchanger (5) of the combustion device (2) (18) and a convection fan (23) to convert the air into hot air through heat exchange; a hot air heating means for performing hot air heating; and a heat exchanger (5) of the combustion device (2). The heated water is exchanged with a floor heating panel (19) consisting of a plurality of heat exchangers (20), and a heating operation is performed mainly using a floor heating means for performing floor heating and the above-mentioned heating and cooling means. and means for switching the operation mode between a heating operation mainly using the floor heating means, and a heating operation mainly using the hot air heating means, the temperature of the hot water being set to a high temperature. 】Enjoy warm air operation?-J Iniu warm air] 1-J perform heating operation mainly using the body hot water setting means and the floor heating means.
Now (Jl, the temperature of the hot water is mainly warmed by hot air)
It consists of a hot water setting means mainly for floor heating, which sets the operating temperature to a low temperature and performs heating operation.

[Function] Floor heating of this invention 1)'a; [If the hot air heater is d3,
The operating mode switching means is J, which allows switching between heating operation mainly using hot air heating means and heating operation using integrated floor heating means, and heating operation mainly using hot air heating means. When performing heating operation, the temperature of the hot water is set to a high temperature using the hot water setting means mainly using hot air. The heating operation is performed by setting the temperature of the hot water to a lower temperature using the setting means than during the heating operation mainly using hot air.
Therefore, depending on the heating purpose, you can arbitrarily select between heating operation based on hot air or heating operation based on floor heating, and each heating operation can be performed at the appropriate hot water temperature that matches the operating mode. It's a monkey. .

The figure shows the "hot water setting routine 1 mainly for floor heating" in the operation mode mainly for floor heating of the hot air heater with heating according to the embodiment of this invention.
In Figure 4, in step S1'1, the temperature of the hot water detected by the temperature/humidity detector (30) is 62 to ε32°C. It is determined whether it is within the range or not. If it is within this range, the current combustion operation is continued in step S12. That is, the same amount of combustion air is blown into the combustion device (2) as at present, and the same amount of fuel is supplied. , and when combustion is in the restricted state, the combustion limiting operation is continued. When the combustion is in the limited operation state, the water temperature (Jj) gradually decreases, and when it is in the full combustion operation state, it gradually covers the upper arm. 313, it is determined whether or not the temperature is 82°C or higher.If the temperature is 82°C or higher, the combustion limiting operation in the combustion device (2) is started in step 51=1.As a result,
The hot water temperature gradually decreases.1 Also, the hot water temperature is 62°C at the platform where the hot water temperature was determined to be 82°C or less in step S13.
Therefore, in step 315, it is determined whether or not the combustion operation in the combustion device (2) is in the combustion restriction operation state.If it is in the combustion restriction operation state, the combustion restriction operation is canceled in step 316, and the normal operation is resumed. Return to full combustion operation state.
The temperature of the water gradually rises. If the combustion limiting operation state is not present in step S 1 J, the current combustion operation is maintained in step 317. In other words, the normal full combustion operation state continues, and the hot water temperature gradually rises.By repeating such hot water temperature control, the combustion operation in the combustion device (2) is adjusted as appropriate, and the average hot water temperature is The temperature is controlled at about 72°C. It should be noted that when the operation control operation is performed in this heating operation mode mainly consisting of warm air, the convection fan (23)
The rotation is set to strong or weak wind mode.The third figure shows the heating operation based on the floor heating D (means or subject), and step 321 is an operation that corresponds to step 311 in Fig. 4.However, In step 321, the water temperature is 57-82°0
It is determined whether or not it is within the range of . Other control operations are shown in FIG. In other words, step 32
2 corresponds to step 312, step S 234 corresponds to step 313, step S24 corresponds to step S1/1, step 325 corresponds to step 511), step 52 (3 corresponds to step 316, and step 327 corresponds to soup pot 317). By repeating such hot water temperature control, the combustion operation in the combustion device (2) is adjusted as appropriate, and the average hot water temperature is controlled at 1.69 and 5°C.
Therefore, the main hot water temperature of this floor 1 heating stage fl, + control operation is a3 (5j1, case, 1 water record GJ, audience calm body heating operation speed J, ri). The temperature will also be set to a low temperature.

Ir, is this heating operation mainly based on floor heating [operation control operation by - mode? The rotation of the convection fan (23) is set to a light wind mode, which is weaker than a weak wind.

As mentioned above, the floor heating (=j warm air heater) of this embodiment transfers hot water heated by the heat exchanger (5) of the combustion device (2) to the heat exchanger (1B) for generating hot air and for convection. A hot air heating means that performs hot air heating by converting heat into warm air through heat exchange with a fan (23), and a heat exchanger (
5) A floor heating means that performs floor heating by exchanging heat with a floor heating panel (19) consisting of a plurality of heat exchangers (20), and heating mainly using the hot air heating means. The operation mode switching means and the heating operation mainly using hot air heating are shown in Figure 3. When doing this, as shown in Figure 4, there is a hot water setting means that mainly uses hot air to set the temperature of hot water to a high temperature (average hot water temperature 72°C) and performs heating operation, and a heating operation that mainly uses floor heating. ``J<'i In the room, the temperature of the sea urchin hot water shown in Figure 5 is lower than that during heating operation with one hot air (
It is equipped with hot water setting means mainly for floor heating, which performs heating operation by setting the average hot water temperature to 69°5°C.

Therefore, when you want to avoid switching between heating operation mainly using hot air heating means and heating operation mainly using floor heating means, it is possible to circulate high-temperature hot water to avoid heating with hot air heating. When it is desired to emphasize heating, hot water at a slightly lower temperature can be circulated, so that heating operation can be performed at an appropriate hot water temperature according to the heating operation state of 1'.

Therefore, the problem of cold air being blown out during heating operation using the hot air heating means as in the conventional system is eliminated, and the function of hot air heating is fully fulfilled. In addition, when you want to avoid underfloor heating in order to increase the humidity of the floor (j2), the hot water for heat exchange can be used at a low temperature, so you can save energy and improve heating efficiency. Heating operation mainly using wind heating means and floor heating m
By appropriately selecting the main heating operation, appropriate and efficient heating can be performed depending on the situation. .

By the way, in the above embodiment, the temperature of the hot water for heat exchange is
We have explained the heating operation control mainly based on Ita wind, which sets the average b) temperature to 72°C, and the heating operation control mainly based on floor covering, which sets the average hot water temperature to 69.5°C. It is not limited to.

[Effects of the Invention] As explained above, the hot air heater of the present invention can switch between the heating operation mainly using the Wenzhou heating UJ means and the floor heating Ft3 stage by means of one switching means. It is difficult to switch between heating operation that mainly uses warm RPA heating means. When performing heating operation mainly using floor heating, the temperature of the hot water is set to a lower temperature than that of heating operation mainly using hot air. 1) Depending on the heating purpose, the heating operation mainly consists of warm air and the heating operation mainly consists of floor heating.
You can choose from six options, and warm each one at the appropriate hot water temperature;
Since it can be operated, the cold 7J can be used for heating operations that emphasize hot air.
There is no fi+ blowing out. In addition, emphasis is placed on underfloor heating.
When the need arises, the hot water for heat exchange can be used at a low temperature, which promotes energy conservation and reduces heating efficiency. Therefore, proper and efficient heating can be performed.
