Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an indoor heating method for heating a room using a heater and a blower for indoor air circulation installed at a location away from the heater.

As shown in FIG. 2, the conventional heating method of this type involves installing a heater 2 on the floor of a room 1 to be heated, and
A downward-blowing type blower 3 is installed near the ceiling in the room 1 away from the heater 2, and during indoor heating, indoor air is circulated as shown by arrows A and B. Person 4 was living near the floor between the two.

In the conventional heating method shown in Fig. 2, when the blower 3 is not installed (see Fig. 1), the warm air heated by the heater 2 rises and only the area near the ceiling is warm, and the area where people live is heated. This was designed in view of the fact that the area near a certain floor surface is not warm, and as a result, a certain degree of effect, that is, the effect that the area near the floor surface becomes warmer, was obtained.

Therefore, at present, the heating method shown in FIG. 2 is exclusively used.

However, the inventors did not settle for the current heating method,
As a result of studies and experiments conducted from various angles in search of more efficient heating and more comfortable heating, it has been found that the current heating method shown in FIG. 2 is not the best method.

In other words, the capacity of heaters, blowers, etc., the volume of the room, the structure of the room,
Although it depends on the structure, the heating method shown in Figure 2 generally requires that there is a large temperature difference between the upper and lower parts of the room, and that the output air of the blower (arrow B) directly affects people. The temperature is the same as when no conventional blower is installed (the earliest heating method, the first
Although it is higher than that shown in the figure), it does not feel as warm, and some people may feel uncomfortable when the output air hits them.

Furthermore, there is a conventional method described in Japanese Utility Model Application Publication No. 52-154068, in which exhaust air discharged from a blower installed at a low position in the room is sent to a high position in the room through a duct. It is discharged from the provided exhaust port.

However, the rotation speed of this blower is always constant, and the length of the duct is also constant, so the structure of the room,
If the structure, size, arrangement of indoor equipment, installation position of the blower, etc. change, there is a problem that comfortable and efficient heating cannot be performed accordingly.

This invention was made to solve the problems, namely:
By reducing the temperature difference between the upper and lower parts of the room (so that the temperature in the lower part is higher), and by preventing the blower's output air from hitting people directly, The purpose is to realize comfortable heating.

The heating method of the present invention will be explained below with reference to the drawings.

3 and 6 are diagrams showing an example of a state in which heating is performed by implementing the method of the present invention, in which 1 indicates a room to be heated;
1a is the floor of the room, 1b is the ceiling of the room, 1c is the side wall of the room, 2 is a heater, 3 is a blower as a blower device for indoor air circulation, 3a is an outer box of the blower as a casing that houses the fan 3b. , 3C is a suction port, and 3d is a blowout port, which faces obliquely upward.

4 is a person.

Here, to explain the structure of the blower 3 shown in FIG. 6, the blower outer box 3a has an air blowing portion 3e that is slidable up and down.
Attach multiple wind direction adjustment plates 3f to the air outlet 3.
d, and the wind direction adjustment plate 3f is pivotally attached to the blowing portion 3e via the pivot shaft 3g to constitute a wind direction adjustment device.

A variable speed motor is used as the drive motor 3h of the fan 3b, so that the rotational speed of the fan 3b is variable, and the height h of the air outlet 3d from the floor 1a is
It is installed at a position that is about the same as, or higher than, the sitting height of the person.

In addition, A is the warm air heated by the heater 2 and trying to rise, B is the output wind of the blower 3, ■ is the wind speed of the output wind B from the outlet 3d, θ is the output wind B from the outlet 3d, This is the blowout angle with respect to the vertical plane.

As shown in FIG. 3, a top-blowing type blower is used as the blower 3, and its output air B is used as the warm air A that is warmed by the heater 2 and rises in the earliest heating method shown in FIG. Blow toward the upper part of the building until it reaches the upper part.
If this is done, as shown in FIG. 3, the output air B of the blower 3 will wrap around or cover from above the warm air A that is heated by the heater 2 and rises.

When the heating method shown in FIG. 3 was used, the temperature at each point in the room was measured, and the results were as shown in Table 1.

Note that the air outlet 3d is located at a height h from the floor 1a.

Figures 4 and 5 are a plan view and a side view showing indoor temperature measurement points. !, f) are indoor temperature measurement points.

Incidentally, the temperature at the same measurement point in the conventional heating method shown in FIG. 2 is as shown in Table 2.

As mentioned above, in the heating method shown in Figure 2, the output air B of the blower 3 directly hits the person 4, so the temperature actually feels lower than the temperature shown in Table 2 (for example, at the measurement point (to) (It's 19 degrees Celsius as shown in the table, but it actually feels like less than 19 degrees Celsius) I feel uncomfortable again.

On the other hand, as is clear from FIGS. 4, 5, and Table 1, the embodiment of the method of the present invention shown in FIG. Space (near the floor,
In addition to the high temperature of the air blowers 3 and 4, the output air B of the blower 3 does not directly hit the person 4, so the person 4 feels much warmer than the conventional heating method shown in FIG. 2, resulting in extremely comfortable heating.

Also, as can be seen from Figure 3, warm air A and the ceiling 1b of room 1
Since the output wind B, which is lower in temperature than the warm air A, is present between the ceiling and the ceiling 1b, there is little heat dissipation through the ceiling 1b, and there is little heat loss, so efficient heating is also performed.

In addition, in the example of the method of this invention shown in FIG. 3, although the airflow flowing into the suction port 3c directly hits the person 4, its speed and density are small compared to the output wind B from the blowout port 3d. In fact, I hardly feel the wind.

Further, with reference to FIG. 6, it is possible to adjust the wind direction (blowout angle θ) as shown by the dotted line and dashed line arrows α and β, and the height of the blowout port 3d is also adjustable. Since the motor 3h is variable speed, the construction, structure, size of the room,
Adjustments can be made to provide the most comfortable and efficient heating by considering the arrangement of indoor equipment and the installation position of the blower.

Figures 7 and 8 show the heating methods considered up to the method of this invention, and both use a top-blowing type blower 3, but in Figure 7, the output air B is lower than the warm air A. In the case of the one shown in FIG. 8, the output air B is directed too upward and does not cover the warm air A from above, which is not preferable.

As explained above, according to the present invention, there is provided a heating device installed indoors, and a wind direction adjustment device installed at a position away from the heating device in the same room as the heating device, and which changes the blowout angle of the output air. The casing has a blow-off part that is slidable in the vertical direction of the casing and has a built-in fan for indoor air circulation and has a variable rotational speed. A blower device is provided at a position higher than the mouth, and the output air of the blower device is blown out toward the upper layer of warm air heated by the heater and rising up, and so as to reach the upper layer. Therefore, it is possible to effectively raise the temperature of the living space of people indoors (especially near the floor surface), and the warm air from the heater and
Since the output air from the blower, which is cooler than the warm air, is interposed between the room ceiling and the room ceiling, there is little heat dissipation through the ceiling.
Therefore, efficient heating can be performed because there is little heat loss.

In addition, the discomfort caused by the output wind can be eliminated or reduced.

1 Furthermore, since the direction, speed, and height of the output air can be selected arbitrarily, the blower can be adjusted according to the structure, structure, size of the room, arrangement of indoor equipment, installation position of the blower, etc. The effect of providing even more comfortable and efficient heating is achieved.
