A supply amount changing means (2) is provided for controlling and adjusting the amount of heat radiated from the heat exchanger (1) while the air flow rate of the circulation fan (4) is constant by the supply amount changing means (2). Is what it is.

The heat exchanger (1) is connected to a water heater (8) via a pump (11) as shown in FIGS. 1 to 3, for example. This water heater (8)
Is pumped out of the heated water of about 80 ° C. by a pump (11) as shown by an arrow C in FIGS. 1 to 3, and in the heat exchanger (1), Is receiving heat from The water heater (8) and the pump (11) may be any other devices that can apply heat to the heat exchanger (1). And, as the water heater (8) is used in the bathroom,
It may be one that supplies hot water to the bathtub.

The circulation fan (4) blows warm air into the bathroom. This circulation fan (4) is, for example, as shown in FIGS.
The motor (14) for operating the motor may be provided in the vicinity thereof. The circulation fan (4) heats the bathroom by blowing warm air as shown by an arrow B in FIGS. 1 to 3 as warm air, and heats the bathroom as required. A suction temperature sensor (10) or the like may be provided in the vicinity of the air suction portion as shown by an arrow A in FIGS.

The supply amount changing means (2) changes the supply amount of hot water to the heat exchanger (1). In the present invention, the supply amount changing means (2) controls and adjusts the amount of heat radiated from the heat exchanger (1) while keeping the air volume of the circulation fan (4) constant. By controlling and adjusting the amount of heat radiation of the heat exchanger (1) as described above, the strength of heating can be adjusted, and the air flow of the circulation fan (4) is constant, so that it is more comfortable than before. It can be controlled.

As in the prior art, as shown in FIGS. 1 to 3, a control circuit (5) is provided for controlling the circulating fan (4), and the water heater (8) is controlled. A hot water supply control circuit (7) may be provided, and the hot water supply control circuit (7) and the control circuit (5) are connected by a communication line (6) to perform an appropriate interlock control. It may be possible to do so.

According to the present invention, by adopting such a configuration, the air volume of the circulation fan (4) is kept constant by the supply amount changing means (2) for changing the hot water supply amount to the heat exchanger (1). However, the amount of heat radiated from the heat exchanger (1) is controlled and adjusted. As a result, the intensity of heating can be adjusted, and the air volume of the circulation fan (4) is constant. In addition, it is possible to perform comfortable control as compared with the related art without the hot air that blows out affecting the perceived temperature.

That is, according to the present invention, it is possible to prevent a user from feeling cold with the hot air without affecting the perceived temperature.

Incidentally, the supply amount changing means (2) is not particularly limited as long as the supply amount of the hot water to the heat exchanger (1) can be changed. In the case shown in FIGS. 2 and 3,
A heat valve (12) opened when supplying hot water to the heat exchanger (1) may be used in the same manner as in the conventional case. Then, as in the case shown in FIG. 1, the supply amount changing means (2) is a motor valve (3) capable of directly adjusting the flow rate of hot water supply to the heat exchanger (1). The flow rate of hot water flowing through the heat exchanger (1) is controlled by the motor valve (3) that can directly adjust the flow rate of hot water supplied to the heat exchanger (1) while the air volume of the circulation fan (4) is constant. , The amount of heat radiation of the heat exchanger (1) is reliably controlled and adjusted. As a result, the intensity of heating can be reliably adjusted, and the circulation fan (4) Since the air volume of (1) is constant, the warm air to be blown out can reliably control the perceived temperature and can perform more comfortable control than in the past. That is, it is possible to ensure that the user does not feel cold with the warm air without the blown warm air reliably affecting the perceived temperature.

As shown in FIG. 2, the supply amount changing means (2) includes a plurality of bypass paths (15) provided in parallel with the heat exchanger (1) and the plurality of bypass paths (15).
The flow control thermal valve (13) provided in each of the circulating fans (4) is formed by the plurality of bypass passages (15) and the flow control thermal valve (13) provided respectively. ), The flow rate of the hot water flowing through the heat exchanger (1) is adjusted while the air volume of the heat exchanger (1) is constant, so that the heat release amount of the heat exchanger (1) is reliably controlled and adjusted.
The strength of the heating can be adjusted reliably,
Moreover, since the air volume of the circulation fan (4) is constant,
It is possible to perform more comfortable control as compared with the related art without the hot air that blows out reliably affecting the sensed temperature. That is, it is possible to prevent the user from surely feeling the cold with the warm air without the blown warm air reliably affecting the perceived temperature.

In particular, as shown in FIG. 2, when the plurality of bypass passages (15) have different thicknesses from each other, the plurality of bypass passages (1) having different thicknesses from each other.
In 5), the flow rate of the hot water flowing to the heat exchanger (1) can be surely adjusted, and the heat radiation amount of the heat exchanger (1) can be controlled and adjusted more reliably. As a result, , The strength of the heating can be more reliably adjusted,
It is possible to perform more comfortable control as compared with the related art without the blown hot air more reliably affecting the perceived temperature. In other words, it is possible to prevent the user from feeling the cold more reliably with the warm air without blowing the warm air more reliably affecting the sensible temperature.

More specifically, as shown in FIG. 2, a plurality of bypass paths (15) are connected to a first bypass path (15a) and a second bypass path (15a).
And the second bypass path (15b) is larger than the first bypass path (15a) when the pipe diameter of the second bypass path (15b) is larger than that of the first bypass path (15a). By opening the second flow control thermal valve (13b) in the vicinity of (15b), a large amount of hot water can be bypassed in the second bypass passage (15b),
As a result, the flow rate of hot water flowing through the heat exchanger (1) can be significantly reduced.

On the other hand, since the pipe diameter of the first bypass path (15a) is smaller than the pipe diameter of the second bypass path (15b), the first bypass path (15a) is provided near the first bypass path (15a). By opening the flow control thermal valve (13a) of No. 1,
A small amount of hot water can be bypassed in the first bypass passage (15a), and as a result, the flow rate of the hot water flowing through the heat exchanger (1) can be slightly reduced.
It is possible to make finer adjustments than when opening the second flow rate adjusting thermal valve (13b).

That is, in the case shown in FIG. 2, the order of heating is as follows: the first flow-adjusting thermal valve (13a) and the second
The strongest heating is performed when both the flow control thermal valve (13b) and the first flow control thermal valve (13b) are closed, and then the first flow control thermal valve (13a) is opened and the second flow control thermal valve (13b) is opened. Valve (1
When 3b) is closed, strong heating is performed. Third, the first flow control thermal valve (13a) is closed, and
When the thermal valve (13b) for adjusting the flow rate is opened, strong heating is performed. The weakest heating is performed when both the first flow control thermal valve (13a) and the second flow control thermal valve (13b) are open.

Incidentally, even if the pipe diameter of the first bypass path (15a) is exactly the same as the pipe diameter of the second bypass path (15b), one of them can be selectively selected. For example, it goes without saying that the above-described adjustment can be freely performed.

Further, as shown in FIG. 3, the supply amount changing means (2) is provided with a plurality of heat exchangers (1) in parallel with a combination utilizing the plurality of heat exchangers (1). The flow control thermal valve (13) provided in each of the plurality of heat exchangers (1) provides a plurality of heat exchangers (1) in combination with the plurality of heat exchangers (1). Thermal valve (13) for adjusting flow rate provided in each exchanger (1)
With this, the flow rate of the hot water flowing through the heat exchanger (1) is adjusted while the air volume of the circulation fan (4) is constant, so that the heat release amount of the heat exchanger (1) can be reliably controlled and adjusted. As a result, it is possible to reliably control the intensity of heating, and furthermore, since the air volume of the circulating fan (4) is constant, the warm air blown out surely affects the sensed temperature. Therefore, it is possible to perform more comfortable control as compared with the related art. That is, it is possible to prevent the user from surely feeling the cold with the warm air without the blown warm air reliably affecting the perceived temperature.

Further, as shown in FIG. 3, if the capacities of the plurality of heat exchangers (1) are different from each other, the plurality of heat exchangers (1) having the capacities different from each other.

Can be more reliably adjusted, and the warm air to be blown out can more reliably control the body temperature without affecting the sensed temperature. In other words, it is possible to prevent the user from feeling the cold more reliably with the warm air without blowing the warm air more reliably affecting the sensible temperature.

More specifically, as shown in FIG. 3, the plurality of heat exchangers (1) consist of a first heat exchanger (1a) and a second heat exchanger (1b). If the capacity of the second heat exchanger (1b) is larger than the capacity of the first heat exchanger (1a), the second flow rate in the vicinity of the second heat exchanger (1b) By opening the adjusting heat valve (13b), a large amount of hot water flows into the second heat exchanger (1b), and as a result, the contribution of the second heat exchanger (1b) is greatly received. The heating can be strengthened.

On the other hand, since the capacity of the first heat exchanger (1a) is smaller than the capacity of the second heat exchanger (1b),
By opening the first flow control thermal valve (13a) provided near the first heat exchanger (1a), a large amount of hot water flows into the first heat exchanger (1a), As a result, the first
Can greatly contribute from the heat exchanger (1a), and the heating can be weakened.

In other words, in the case shown in FIG. 3, the order of the heating intensity is as follows.
And the thermal valve (13b) for adjusting the flow rate
The strongest heating is provided when the first heat exchanger (1a) and the second heat exchanger (1b) are working together,
Next, the first flow control thermal valve (13a) is closed,
The second flow control thermal valve (13b) is open and the second
When only the heat exchanger (1b) is operated, strong heating is performed. Then, the first flow control thermal valve (13a) is opened, the second flow control thermal valve (13b) is closed, and only the first heat exchanger (1a) operates. The weakest heating is done when you are.

It should be noted that even if the capacity of the first heat exchanger (1a) and the capacity of the second heat exchanger (1b) are completely the same, one of them is selectively selected. For example, it goes without saying that the above-described adjustment can be freely performed.

If a motor valve (3) capable of directly adjusting the flow rate of the hot water supply is used instead of the above-mentioned flow-adjusting thermal valve (13), the flow-adjusting thermal valve (1) is used.
The flow rate of the hot water flowing to the heat exchanger (1) can be reliably adjusted by the motor valve (3) capable of directly adjusting the flow rate of the hot water supply amount instead of the heat water supply amount (3). The amount of heat radiation can be controlled and adjusted more reliably, and as a result, the intensity of heating can be more reliably adjusted, and the warm air blown out more reliably affects the perceived temperature. Therefore, it is possible to perform more comfortable control as compared with the related art. In other words, it is possible to prevent the user from feeling the cold more reliably with the warm air without blowing the warm air more reliably affecting the sensible temperature.

As shown in FIGS. 1 to 3, if a hot water temperature sensor (9) for detecting hot water temperature is provided near the supply amount changing means (2), the supply amount changing means ( Hot water temperature sensor (9) installed near 2)
By detecting the temperature of the hot water, it can be useful when adjusting the flow rate of hot water flowing through the heat exchanger (1), which is very useful.

The amount of heat is controlled and adjusted. As a result, the intensity of heating can be adjusted.
