DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the following three drawings. The room is a bathroom as an example.

FIG. 1 is an internal front view of one embodiment of the present invention, FIG. 2 is an internal plan view of one embodiment of the present invention, and FIG. 3 is an internal side view of one embodiment of the present invention.

In the drawing, reference numeral 1 denotes a housing, which is an indoor unit 8 and an outdoor unit 9.
An opening 1a is provided in a part of the side of the wall 10 that separates the wall 10 from the side of the outside 9 in contact with the wall 10. Reference numeral 2 denotes a heat source for heating, which is provided inside the housing 1.

Reference numeral 3 denotes a blower, which is disposed above the heat source 2 inside the housing 1 and blows circulating wind. A casing 4 is provided around the blower 3 and also covers the heat source 2.

Reference numeral 5 denotes a ventilation fan, which is disposed beside the blower 3 inside the housing 1, and rotates the air in the room 8 to be described later by a duct 13, an air reservoir 12, a ventilation nose 7c.

Reference numeral 7 denotes a dividing plate which is provided between the heat source 2, the blower 3, the ventilation fan 5 and the wall 10, and has the following three perforations. Reference numeral 7a denotes a blow-out portion, which constitutes a part of a passage for guiding the air heated by the heat source 2 to the room 8 at a position behind the heat source 2.

Reference numeral 7b denotes a blower nose, which constitutes a part of a passage for sucking air in the room 8 into the blower 3 at a position behind the blower 3.

Reference numeral 7c denotes a ventilation nose, which constitutes a part of a passage for sucking air in the room 8 into the ventilation fan 5 at a position behind the ventilation fan 5.

An electric motor 11 is mounted on the casing 4 and drives and rotates the blower 3. Reference numeral 12 denotes an air reservoir, which is a space surrounded by the housing 1 and the dividing plate 7.

Reference numeral 13 denotes a duct, which is located behind the blower 3 and is connected to an opening 1a provided in the housing 1 and has a wall 10;
And constitutes a passage through the casing 1 and the room 8. 14 is a partition plate provided inside the duct 13,
The duct 13 is divided into the following two passages.

Reference numeral 14a denotes a blowing passage which constitutes a passage leading to the heat source 2, and blows out high-temperature air sent from the blower 3 and subjected to heat exchange by the heat source 2 into the room 8. Reference numeral 14b denotes a suction passage which constitutes a passage leading to the blower 3 and the ventilation fan 5, and sucks air in the room 8 into the housing 1.

At this time, the partition plate 14 is arranged so that the area of the outlet passage 14a is smaller than the area of the suction passage 14b. More specifically, since the partition plate 14 is formed of a flat plate, the partition plate 14 is arranged close to one side so that the outlet passage 14a is narrow and the inlet passage 14b is wide.

Reference numeral 15 denotes a grill, which is attached to the interior of the duct 13 on the room 8 side, and protects the opening of the duct 13 on the interior 8 side. Reference numeral 16 denotes a louver which is attached to the opening of the interior of the interior of the outlet passage 14a of the grill 15 so that the interior 8 side is inclined downward, and guides warm air blown into the interior 8 through the outlet passage 14a to the lower portion of the interior 8. It is.

Reference numeral 17 denotes a ventilation fan motor for driving and rotating the ventilation fan 5.

In the above configuration, three operations will be described.

The operation during the heating operation, which is the first operation, is as follows.

The air in the room 8 such as a bathroom is supplied to the grill 15 and the duct 1 by the rotation of the blower 3 driven by the electric motor 11.
The air flows to the heat source 2 through the suction passage 14b, the air reservoir 12, the blower nose 7b formed in the dividing plate 7, and the blower 3 inside the blower 3.

The air that has reached the heat source 2 undergoes heat exchange due to the heat generated by the heat source 2 and becomes high in temperature. The air further passes through an outlet 7 a formed in the dividing plate 7, an outlet passage 14 a in a duct 13, and a grill 15. The wind direction is changed downward by the louver 16 of the section, and the air is blown into the room 8 to heat the room 8.

At this time, the partition plate 14 is arranged in the duct 13 so that the area of the outlet passage 14a is smaller than the area of the suction passage 14b.
When the air passes through the air passage 4b, the flow velocity is slow because the area of the suction passage 14b is large, so that the passage resistance is reduced and a large amount of air can be sucked.

The hot air that has passed through the heat source 2 and has become high temperature is:
When passing through the outlet passage 14a, the flow velocity increases due to the reduced area of the outlet passage 14a, and passes through the louver 16 of the grill 15 portion. At this time, since the louver 16 is inclined downward, the warm air is sent to the feet of the bather in the room 8. That is, the coldness of the bather in the washroom or the like during cold weather is eliminated.

In this case, the outlet passage 14 in the duct 13
Since the area of a is narrow, the air passage resistance in this passage increases, and there is a concern that noise may increase.
Since the area of the suction passage 14b in the duct 13 is large, the air passage resistance in the blow passage 14a is small.

Therefore, there is no increase in the passage resistance of the air in the entire passage of the heating, ventilation and drying machine. Therefore, it is not necessary to increase the electric power of the electric motor 11 for the blower 3, and it is possible to send warm air to the feet of the bather in the room 8 without increasing noise.

The operation during the clothes drying operation, which is the second operation, is as follows.

The air in the room 8 such as a bathroom is supplied to the grill 15 and the duct 1 by the rotation of the blower 3 driven by the electric motor 11.
The air flows to the heat source 2 through the suction passage 14b, the air reservoir 12, the blower nose 7b formed in the dividing plate 7, and the blower 3 inside the blower 3.

The air that has reached the heat source 2 undergoes heat exchange due to the heat generated by the heat source 2 and has a high temperature. The air passes through a blowout portion 7a formed in the split plate 7 and a blowout passage 14a in a duct 13.
The wind direction is changed downward by the louver 16 of the grill 15 and is blown into the room 8 to heat and dry the clothes in the room 8.

At the same time, the ventilation fan 5 is also driven and rotated by the ventilation fan motor 17, and the air containing moisture evaporated from the clothes passes through the grill 15, the suction passage 14b in the duct 13, the air reservoir 12, and the ventilation nose 7c. It reaches the ventilation fan 5 and is discharged outside 9.

In this case, the suction passage 14b in the duct 13
Is the sum of the air for drying clothes and the air for ventilation. However, since the area of the suction passage 14b is large and the passage resistance is small, the air for the blower 3 is required to secure a predetermined air volume. There is no need to increase the power of the motor 11.

The operation during the ventilation operation, which is the third operation, is as follows.

The air in the room 8 such as a bathroom flows to the ventilation fan 5 through the following two passages by the rotation of the ventilation fan 5 driven by the ventilation fan motor 17.

The first passage includes the grill 15 and the duct 1
3, suction passage 14b, air reservoir 12, ventilation nose 7c
Through the ventilation fan 5.

The second passage is the louver 1 of the grill 15
6, through the outlet passage 14a in the duct 13, the outlet 7a, the heat source 2, the blower 3, the blower nose 7b, and the air reservoir 12 to reach the ventilation fan 5.

The air having passed through the two passages and joined by the ventilation fan 5 is discharged to the outside 9 by the ventilation fan 5.

In this case, most of the air reaching the ventilation fan 5 passes through the first passage including the suction passage 14b having a small passage resistance. This means that it is not necessary to increase the power of the electric motor 11 for the blower 3 to secure a predetermined air volume.

In the above embodiment, a bathroom is used as an example of a room, but the present invention can be applied to other rooms.

[0053]

As described above, according to the heating / ventilating / drying machine of the present invention, the inside of the duct penetrating the wall separating the room and the outside is separated by the partition plate into the blow-out passage leading to the heat source, the blower and the ventilation fan. The suction passage is divided into two passages, and the partition plate is arranged so that the area of the discharge passage is smaller than the area of the suction passage.Therefore, without increasing the power of the electric motor that drives and rotates the blower, during the heating operation. By sending warm air to the feet of the bathers in the washing room, etc., the cold during cold weather can be eliminated.

At the same time, the noise during each operation such as the heating operation, the clothes drying operation, and the ventilation operation does not increase, so that discomfort due to the noise is given to a person in the room or a person in the next room. There is no practical effect, which is a great effect in practical use.
