Hereinafter, the water vapor exhaust mechanism will be described.

(Water vapor exhaust mechanism) FIG. 3(a) shows the back of the heating conditioner 1 shown in FIG. 1, and (b) shows the state where the exhaust hood (mixing exhaust pipe) 50 is removed from the heating conditioner shown in (a). (C) is a diagram showing the back of the state in which the rear panel (cooling air exhaust pipe) 40 is removed from the state shown in (b). 4(a) to (c) are diagrams showing the flow of water vapor and cooling air. 5( a) and (b) are diagrams showing the front and back of the rear panel 40. Here, the cooling air is the air after cooling the object to be cooled in the heating conditioner, and the temperature and humidity are very low compared to the water vapor discharged from the heating chamber 2a.

As shown in FIG. 3( a ), a rear panel 40 and an exhaust pipe 50 are attached to the back of the cabinet (housing) 2 of the heating conditioner 1.

As shown in FIG. 3( b ), the rear panel 40 is attached so as to cover the back surface of the cabinet 2, and a plurality of cooling air exhaust ports 40 b for discharging cooling air are provided in the upper part. Thus, the rear panel 40 functions as a cooling air exhaust pipe for discharging the cooling air that has cooled the surroundings of the housing 2 from the cooling air exhaust port 40b by being attached to the back surface of the housing 2.

The rear panel 40 is formed with water vapor exhaust ports 40a so as to be sandwiched by cooling air exhaust ports 40b from both sides. The water vapor exhaust port 40a is formed on the upper side of the rear panel 40 (the top surface 2c of the cabinet 2) and communicates with the exhaust port 30a of the first exhaust pipe 30 described later. Therefore, cooling air exhaust ports 40b are formed on both sides of the water vapor exhaust port 40a. In addition, in this embodiment, as shown in FIGS. 3 and 5, the cabinet 2 is viewed from the back, and the water vapor exhaust port 40 a is slightly shifted from the center of the cabinet 2 to the right side. As a result, one cooling air exhaust port 40b is formed on the right side of the water vapor exhaust port 40a, and three cooling air exhaust ports 40b are formed on the left side.

The air containing water vapor (hereinafter, simply referred to as water vapor) discharged from the water vapor exhaust port 40a and the cooling air discharged from the cooling air exhaust port 40b are shown in FIG. 3(a). In the state where the exhaust hood 50 is attached, the exhaust hood 50 is mixed, and in a state where water vapor is diluted by cooling air, it is blown out to the front of the cabinet 2, that is, the front side of the heating conditioner 1.

The flow of water vapor and cooling air discharged from the exhaust hood 50 is as shown in (a) to (c) of FIG. 4. Here, the opening side of the heating chamber 2a of the heating conditioner 1 is a front.

Water vapor system: As shown in FIG. 4(a), it is discharged from the second exhaust pipe 32 formed on the left side of the cabinet 2 and communicating with the interior of the heating chamber 2a (1), as shown in FIG. 4(b) As shown, it is discharged to the first exhaust pipe 30 (2) provided on the exhaust port side of the second exhaust pipe 32, and is discharged from the exhaust port 30a of the first exhaust pipe 30 (3), and finally from the exhaust The gas hood 50 is discharged to the outside (4). That is, the first exhaust pipe 30 and the second exhaust pipe 32 constitute a water vapor exhaust pipe.

On the other hand, the cooling air is generated by a cooling fan (not shown) provided on the bottom surface of the cabinet 2, as shown in FIG. 4(b), from both sides of the exhaust port 30a of the first exhaust pipe 30 It is discharged (5) (6), and finally mixed with water vapor in the exhaust hood 50 and then discharged to the outside.

Since the water vapor (4) discharged from the exhaust hood 50 is enclosed by the cooling air (5) (6) discharged from both sides of the water vapor (4), the cooling air (5) ) (6) The fully diluted state is discharged to the outside of the heating conditioner 1.

(effect) According to the heating conditioner 1 configured as above, since the cooling air exhaust ports 40b are formed on both sides of the water vapor exhaust port 40a, the water vapor discharged from the water vapor exhaust port 40a is removed from the cooling air from both sides The cooling air discharged from the exhaust port 40b is sandwiched. As a result, in the exhaust hood 50, water vapor becomes easier to mix with cooling air whose temperature/humidity is very low compared to the water vapor. Therefore, the air discharged from the exhaust hood 50 becomes humidity as a whole Gas that becomes lower and temperature becomes lower (water vapor that is sufficiently diluted). Therefore, the gas discharged from the mixing exhaust pipe makes it difficult for the body of the heating conditioner 1 and the wall surface near the heating conditioner 1 to condense.

In addition, in the present embodiment, in particular, the momentum regarding the blowing of the gas discharged from the exhaust hood 50 of the heating conditioner 1 is not considered. That is, if the air containing water vapor is exhausted as much as possible, it can be hardly condensed on the wall surface of the main body of the heating conditioner 1 and the heating conditioner 1. In the following second and third embodiments, an example for expelling air containing water vapor from the exhaust hood 50 while taking advantage of the situation will be described.

[Embodiment 2] Hereinafter, other embodiments of the present invention will be described. In addition, for the convenience of description, components having the same functions as those described in the above-mentioned embodiment are denoted by the same symbols, and the descriptions thereof are not repeated.

FIG. 6 shows the first exhaust pipe 30 included in the heating conditioner of the present embodiment, (a) shows the side (front view side) when it is mounted on the cabinet 2, and (b) shows (a) The back side.

The heating conditioner of this embodiment has substantially the same configuration as the heating conditioner 1 of the first embodiment described above, and as shown in FIG. 6( b ), the exhaust port 30 a of the first exhaust pipe 30 is provided with ribs 31. Points are different. That is, the flow path in the first exhaust pipe 30 is provided with a rib 31 that narrows the flow path toward the exhaust port 30a side.

The rib (flow path width adjusting member) 31 is composed of a plate-shaped member for narrowing the exhaust port 30a. With the rib 31, in the flow path from the inlet 30b of the first exhaust pipe 30 to the exhaust port 30a, the flow path gradually narrows from the near side of the exhaust port 30a. As a result, the pressure in the flow path increases, and water vapor is expelled from the exhaust port 30a. For example, as shown in FIG. 3(b), the cooling air exhaust port 40b that discharges cooling air at the center side of the cabinet 2 is provided more than the water vapor exhaust port 40a that discharges water vapor. To easily dilute water vapor with cooling air, it is preferable to provide the rib 31 in such a manner that the flow path from the inlet 30b of the first exhaust pipe 30 to the exhaust port 30a narrows toward the center side of the cabinet 2. In this case, since water vapor is discharged on the center side of the cabinet 2 (the side where more cooling wind is discharged), it becomes exposed to more cooling wind. As a result, the water vapor is discharged to the outside of the cabinet 2 in a more diluted state (a state in which the concentration of water vapor is low).

In order to narrow the exhaust port 30a, in addition to using the ribs 31 described above, the exhaust port 30a may be reduced to a certain degree when the first exhaust pipe 30 is formed, as long as the exhaust port 30a The structure containing water vapor can be discharged regardless of the structure.

For example, the cross-sectional area orthogonal to the direction in which the water vapor flows through the water vapor flow path in the first exhaust pipe 30 is discharged from the water vapor inlet port 30b side as compared with the water vapor The side of the exhaust port 30a may be small.

As described above, since steam is discharged from the exhaust port 30a of the first exhaust pipe 30, it is more difficult to condense in the wall of the heating conditioner 1 body and the heating conditioner 1 vicinity.

As another method for discharging water vapor while taking advantage of the situation, it may be considered to design the structure of the exhaust hood 50. This point will be described in the third embodiment below.

[Embodiment 3] Hereinafter, other embodiments of the present invention will be described. In addition, for the convenience of description, components having the same functions as those described in the above-mentioned embodiment are denoted by the same symbols, and the descriptions thereof are not repeated.

7 shows the exhaust hood 50 included in the heating conditioner of the present embodiment, (a) shows the side (front side) that can be seen when it is mounted on the cabinet 2, (b) shows the back side of (a) side. 8 is a sagittal cross-sectional view taken along line AA of FIG. 7(a).

As shown in FIG. 8, the exhaust hood 50 is attached to the cabinet 2 so that the exhaust port 50 a faces the top surface 2 c side of the cabinet 2.

In order to reduce the resistance of the gas flowing through the flow path 51 of the exhaust hood 50 as much as possible, the height difference of the wall surface 51a on the upper side of the flow path 51 is reduced. That is, the exhaust hood 50 is configured so that the gas passing through the flow path 51 can be smoothly discharged from the exhaust port 50a. In addition, by adjusting the inclination angle of the wall surface 51a of the flow path 51 near the exhaust port 50a, it becomes possible to adjust the exhaust direction of the gas discharged from the exhaust port 50a. For example, by inclining the wall surface 51a near the exhaust port 50a with respect to the top surface 2c of the cabinet 2, the gas flowing through the flow path 51 can be opposed to the top surface 2c of the cabinet 2 from the exhaust port 50a It is discharged obliquely upward. Thus, it is possible to suppress the air containing water vapor from being blown onto the top surface 2c of the cabinet 2. Therefore, in order to suppress the blowing of air containing water vapor on the top surface 2c of the cabinet 2, in the exhaust hood 50, the wall surface 51a, which is a part of the inner wall constituting the flow path 51 communicating with the exhaust port 50a, is preferably opposed to The inclined surface inclined upward from the top surface 2c of the cabinet 2 toward a predetermined angle.

[Modification] Although in the first to third embodiments described above, the water vapor exhaust port 40a in the rear panel 40 is formed at a position shifted from the center, the water vapor exhaust port 40a may be formed at the center. That is, the water vapor exhaust port 40a may be formed in the center of the back surface of the cabinet 2. In this case, in the rear panel 40, two cooling air exhaust ports 40b are formed on both sides of the water vapor exhaust port 40a, thereby making it easier to dilute the air containing water vapor with the cooling air.

In addition, if the steam exhaust port 40a is formed at a position where the cooling air exhaust ports 40b are formed on both sides of the water vapor exhaust port 40a (left, right, up, down, and in any direction), the upper part of the rear panel 40 may not be necessary Side, but may also be the lower side or other positions.

Embodiments obtained by appropriately combining the technical methods disclosed in different embodiments are also included in this The technical scope of the invention. Furthermore, by combining the technical methods disclosed in the respective embodiments, it is possible to form new technical features.
