Description

  The present invention relates to an indoor drying apparatus that ventilates a room such as a bathroom or a dressing room while heating the room.

FIG. 4 is a schematic perspective view of a conventional bathroom drying apparatus as an indoor drying apparatus installed on the ceiling (A) of the bathroom as viewed from below.
The appliance body (B) of the bathroom drying device is disposed on the ceiling of the bathroom, and the rectangular body case (1) of the appliance body (B) is longitudinally separated by a partition wall (100). 1 is divided into second compartments (1A) (1B). The lower surface opening (11) of the first compartment (1A) faces the appliance installation opening (A1) opened in the ceiling (A) of the bathroom, and the lower surface opening (11) is a grill plate (not shown). Covered.

The first compartment (1A) has a heat-dissipating heat exchanger (23) in which hot water pipes (21) and (21) penetrate through a group of fins (22) and (22), and a fan for sucking air in the bathroom ( 24) and a pair of guide walls (25) and (26) for guiding the discharge air from the fan (24) downward, and a warm air heating function part (2) is accommodated, and the guide wall (25) and (26) are integrally formed with the main body case (1).
The partition wall (100) of the first and second compartments (1A) (1B) is provided with a vent (13), and the air passing through the vent (13) is passed through the second compartment (1B). ) Is exhausted to the outside through a ventilation fan (14) disposed in the room.

  In this system, when hot water is supplied to the hot water pipe (21) of the heat exchanger (23) for heat dissipation and the fan (24) is rotated, the air in the bathroom is sucked into the fan (24) and the heat for heat dissipation. Heated when passing through the exchanger (23), the heated discharge air from the fan (24) is discharged into the bathroom from the hot air discharge port (27) between the lower ends of the guide walls (25) and (26). Thus, bathroom heating can be performed.

On the other hand, when the ventilation fan (14) is driven in the state where the bathroom heating is continued, it exists between the inner peripheral side surface of the first compartment (1A) and the outer peripheral side surface of the hot air heating function unit (2). Air flows through the path of the side ventilation gap (12) → ventilation port (13) → ventilation fan (14) that is discharged to the outside, thereby performing bathroom drying in which bathroom heating and ventilation operate simultaneously The
In addition, if only the ventilation fan (14) is operated in a state where the hot-air heating function unit (2) is stopped, the air in the bathroom is discharged to the outside through the above-described path, and the bathroom can be ventilated.

However, the conventional device has a problem that a sufficient ventilation rate cannot be obtained during a drying operation or a ventilation operation.
The above problem will be further described in detail.
In recent years, when the product is made compact from the viewpoint of easy handling of the product and efficient use of the installation space and the storage space at the time of inventory, the side ventilation gap (12) tends to be narrowed. As a result, the ventilation resistance during the ventilation operation for operating the ventilation fan (14) is increased, so that the air in the bathroom is exhausted from the portion close to the ventilation port (13) in the side ventilation gap (12) exclusively. It is sucked into the mouth (13) and cannot perform ventilation operation using the entire side ventilation gap (12).
For this reason, in the above-mentioned conventional one, a sufficient ventilation amount cannot be obtained during the drying operation or the ventilation operation.
This invention is made in view of this point, and makes it the subject to obtain sufficient ventilation volume at the time of dry operation or ventilation operation.

The air flowing into the gap flows through the side ventilation gap and the bottom ventilation gap that follows, and flows toward the ventilation port (13).
Accordingly, the ventilation resistance of the entire ventilation gap is reduced by the amount of the new bottom ventilation gap formed between the bottom plate of the main body case (1) and the bottom plate of the casing for the heating function unit, thereby enabling the drying operation and ventilation. Sufficient ventilation can be secured during operation.

(2) About the invention of claim 2 In the invention of claim 1,

It is a guide wall (25). In addition, the other guide wall (26) is arranged in parallel at the position corresponding to the vicinity of the downstream end of the guide wall (25), and the lower end of these guide walls (25) and (26) is a hot air discharge port ( 27) (corresponding to the “discharge port” which is the specific matter of the invention described above) and the hot air discharge port (27) is covered with a louver (270) as shown in FIG.

As shown in FIG. 2, a mounting flange (201) having intake slits (201 a) (201 a) is provided on the outer periphery of the lower end of the heating function unit casing (20). Then, when the heating function part casing (20) is inserted into the heating outer box (4) until the mounting flange (201) contacts the peripheral edge of the opening (44) of the heating outer box (4), A bottom ventilation gap (121) through which ventilation air flows is formed between the bottom plate (42) of the outer box (4) and the bent plate (20c) constituting the bottom plate of the casing for heating function unit (20). It is like that. Further, a side ventilation gap (12) is formed across the entire circumferential direction between the inner peripheral side surface of the rectangular frame portion (41) of the outer casing for heating (4) and the outer peripheral side surface of the casing for heating function unit (20). The group of the side ventilation gap (12) and the bottom ventilation gap (121) corresponds to the “ventilation gap” which is the above-mentioned specific matter of the invention. In the present embodiment, the outer surface of the “circumferential side plate bent from the periphery of the bottom plate of the heating function portion casing”, which is the above-described specific matter of the invention, corresponds to the outer peripheral side surface of the heating function portion casing (20). .

  Therefore, when the ventilation fan (14), which will be described later, is operated, the entire area in the circumferential direction of the side ventilation gap (12) formed between the outer casing for heating (4) and the casing for heating function section (20) is formed. The inflowing air flows through a path connected from the bottom ventilation gap (121) to the ventilation fan (14) via the ventilation port (13). Therefore, the entire ventilation gap (side ventilation gap (12) is compared to the conventional one, as much as the bottom ventilation gap (121) is formed between the main body case (1) and the heating function casing (20). ) And the bottom ventilation gap (121)) are reduced in ventilation resistance, so that a sufficient amount of ventilation can be secured during drying and ventilation operations.

Further, in the indoor drying apparatus according to the present embodiment, the ventilation port (13) is positioned in the vicinity of the bottom plate (42) of the heating outer box (4) (in the vicinity of the bottom ventilation passage (121)), The air in the bottom ventilation passage (121) can be sucked smoothly, and the ventilation rate can be further increased.
Further, in the heating function section casing (20), adjacent to the guide wall (25) (26) arrangement section, a large number of fins (22) (22) are arranged in parallel and penetrate these. A heat-dissipating heat exchanger (23) comprising hot water pipes (21) and (21) is disposed, and the heat-dissipating heat exchanger (23) of the lower end opening of the heating function unit casing (20) The portion corresponding to is the heating inlet (28) which is the “air suction port” of the above-mentioned invention specific matter. Further, the heat radiating heat exchanger (23) is supplied with hot water from a water heater (not shown) installed outdoors.

  A fan (24) is disposed on the back side of the heat radiation heat exchanger (23), and the fan (24) is rotated by a motor (M) as shown in FIG. It has become. As a result, the air warmed by the heat-dissipating heat exchanger (23) is sucked by the fan (24) and discharged from the hot air discharge port (27) to the bathroom.

[Ventilation outer box (3) etc.]
The ventilation outer box (3) connected to the fitting cylinder (45) protruding from the side wall (41a) of the heating outer box (4) is formed in a flat rectangular box shape, and the ventilation outer box In (3), a ventilation fan (14) for sucking air in the heating outer box (4) through the ventilation port (13) is housed, and a discharge port (140 for the ventilation fan (14)). ) Communicates with a ventilation duct connecting cylinder (33) projecting from the side wall of the ventilation outer box (3). In addition, the connecting tube portion (5) connected to the peripheral portion of the through hole (36) formed in the side wall of the ventilation outer box (3) projects from the side wall (41a) of the heating outer box (4). The fitting tube (45) is fixed by external fitting.

[Actual behavior]
Next, the actual operation of the indoor drying apparatus will be described.
When hot water is supplied to the hot water pipe (21) of the heat dissipating heat exchanger (23) and the fan (24) is rotated, the air in the bathroom is sucked by the fan (24) and the heat dissipating heat exchanger (23 The heated discharge air from the fan (24) is discharged into the bathroom from the hot air discharge port (27) between the downstream ends of the guide walls (25) and (26). Thus, bathroom heating is performed.

On the other hand, when the ventilation fan (14) is driven while the bathroom heating is continued, the drying operation is started.
That is, as described above, the bathroom air flowing into the entire circumferential direction of the side ventilation gap (12) formed between the heating outer box (4) and the heating function casing (20) is, It flows in a path that leads from the bottom ventilation gap (121) to the ventilation fan (14) via the ventilation port (13). Therefore, the entire ventilation gap (side ventilation gap (12) is compared to the conventional one, as much as the bottom ventilation gap (121) is formed between the main body case (1) and the heating function casing (20). ) And the bottom ventilation gap (121)) is reduced in ventilation resistance, so that a sufficient ventilation rate can be ensured during the drying operation. Further, in this bathroom drying apparatus, the ventilation resistance of the entire ventilation gap is lowered by the formation of the bottom ventilation gap (121), so that a sufficient ventilation amount is ensured without increasing the rotational speed of the ventilation fan (14). As a result, the number of rotations of the ventilation fan (14) can be suppressed and noise can be reduced.

In addition, if only the ventilation fan (14) is operated in a state where the hot-air heating function unit (2) is stopped, the air in the bathroom is discharged to the outside through the above-described path, and the bathroom can be ventilated. In this case as well, the presence of the bottom ventilation gap (121) described above reduces the ventilation resistance of the entire ventilation gap and ensures a sufficient ventilation rate, as in the case of the drying operation.
In the above embodiment, the ventilation opening (13) opened in the side wall (41a) of the rectangular frame portion (41) is positioned in the vicinity of the bottom plate (42) of the heating outer box (4). The ventilation port (13) may be formed in the bottom plate (42) of the heating outer box (4).

  The present invention can be used as a drying device in various rooms such as a living room, a dressing room, and a factory.
