Abstract

PROBLEM TO BE SOLVED: To reliably recover condensate without sticking a heat insulation material at a vapor condensation part. SOLUTION: An air-conditioner comprises a heat-exchanger situated in a casing; and a pan situated on the heat-exchanger side and recovering condensate adhered to the surface of a constitution part situated in a wall plate 4 on the heat-exchanger side and other casing. A continuous uneven surface part 4a, such as a waveform, a triangular, or a square uneven surface part, is formed in a direction, in which condensate flows, in the surface of a wall plate on the heat-exchanger and other constituting part. This constitution, since condensate is decreased in a quantity each time the condensate flows over a protrusion part, prevents the condensate from dropping from the surfaces of a heat- exchanges side wall plate and other part.

FIG. 2A shows a heat exchanger side wall plate having a flat surface, and FIG. 2B shows a heat exchanger side wall plate having a continuous wave-shaped uneven portion.

1 to 4, reference numeral 1 denotes an air conditioner main body, 2 denotes a housing of the air conditioner main body 1, and 3 denotes a housing 1
It is a heat exchanger arranged in. Reference numeral 4 denotes a heat exchanger side wall plate formed on the side wall of the heat exchanger 3. Reference numeral 4 a denotes a heat exchanger side wall plate 4 formed on the surface of the heat exchanger side wall plate 4. Reference numeral 6 denotes a recess for preventing continuous water waves, for example, which is disposed on the lower side of the heat exchanger 3 and collects dew water 5 condensed on the side wall plate 4 of the heat exchanger.

Next, a specific description will be given of the operation in which the dew condensation water 5 condensed on the surface of the heat exchanger side wall plate 4 in the present embodiment. A heat exchanger side wall plate 4 is attached to a side surface of the heat exchanger 3. As shown in FIG. 2B, the surface of the heat exchanger side wall plate 4 according to the present embodiment has a dew condensation water, as shown in FIG. In order to prevent the flow of 5, for example, a continuous wave-shaped uneven portion 4 a is formed on the outside.

The continuous wave-shaped uneven portion 4a formed on the surface of the heat exchanger side wall plate 4 is formed in the direction in which the dew condensation water 5 flows, and the pitch of the unevenness is, for example, 6 mm, and the height of the unevenness is, for example, 1 mm. It is formed with. The irregularities 4a on the surface of the heat exchanger side wall plate 4 formed with this pitch and height can be used as a barrier for preventing the flow of the dew condensation water 5 from flowing.

As shown in FIGS. 3 (a) and 3 (b), the dew water 5 condensed on the surface of the outer heat exchanger side wall plate 4 gets over the convex portion (mountain) of the continuous wave-shaped uneven portion 4a. Each time the amount decreases sequentially. FIG. 3A shows a state before the dew water 5 condensed on the concavo-convex portion 4a passes over the convex portion of the concavo-convex portion 4a, and FIG. 3B shows a state of the condensed water 5 condensed on the concavo-convex portion 4a. It shows a state in which a part of the condensed water 5 in the traveling direction is reduced, as a part of the condensed water 5 goes over the convex part of the concave and convex part 4a and is separated before and after the convex part.

Condensed water 5 which has proceeded in the direction in which the projection flows.
In each case, the amount of the dew condensation water 5 is gradually reduced each time the projections of the continuously formed concavo-convex portions 5 are sequentially exceeded. As a result, the flow of the dew condensation water 5 is suppressed. In addition, the amount of the dew water 5 that has stayed without exceeding the convex portion of the concave and convex portion 4a increases when the dew water 5 that has newly condensed or the dew water 5 that has exceeded the convex portion on the front side is newly added. Will flow out.

The condensed water 5, which has flowed out,
Since the amount of the dew condensation water 5 is gradually reduced every time the projections of the concavo-convex portion 4a are sequentially exceeded, the flow of the dew condensation water 5 is suppressed. If the condensed water 5 does not flow out without being newly added to the condensed water 5, the condensed water 5 evaporates spontaneously without separating from the surface of the heat exchanger side wall plate 4 and falling.

As described above, in the present embodiment, since the concave and convex portions 4a for preventing the flow of the dew condensation water 5 are continuously formed on the surface of the outer heat exchanger side wall plate 4, the outer heat exchanger side wall plate is formed. Dew condensation 5 on the surface of the uneven portion 4a on the surface of the plate 4
As shown in FIGS. 3A and 3B, the amount of the dew water 5 can be gradually reduced every time the vehicle passes over the convex portion (mountain) of the continuous wave-shaped uneven portion 4a. Can be suppressed.

For this reason, as shown by arrows A1 and A2 in FIG. 4, the dew condensation water 5 flowing toward the receiving pan 6 can be made hard to separate from the surface of the heat exchanger side wall plate 4.
It is possible to make it hard to drop to the outside of the tray 6. Further, in the present embodiment, when the dew condensation water 5 is collected in the receiving pan 6, the flow of the dew condensation water 5 can be suppressed, so that the dew condensation water 5 can be slowly dropped onto the receiving pan 6, and 5 is less likely to bounce on the surface of the receiving pan 6, and can be prevented from being released to the outside of the receiving pan 6.

Therefore, the dew condensation water 5 can be efficiently collected in the tray 6 without attaching a heat insulating material to the surface of the heat exchanger side wall plate 4 to be condensed. In addition, since the conventionally required heat insulating material can be made unnecessary, it is possible to prevent an increase in the number of parts, work steps, and deterioration in recyclability due to the heat insulating material.

In this embodiment, as shown in FIG. 1, when there are restrictions on the height and depth of the indoor unit in the housing 1, in order to improve the performance while observing the restrictions, a heat exchanger is used. 3 is configured by securing the surface area of the heat exchanger 9 by bending the lower part of the heat exchanger 3 by retracting. For this reason, the receiving tray 6 can be inserted deeper than the end surface of the heat exchanger side wall plate 4.

At this time, if the dew condensation water 5 condensed on the side wall plate 4 of the heat exchanger is strong, the dew condensation water 5 is separated from the surface of the lower part of the heat exchanger 3 and drops. However, in the present embodiment, as shown in FIG. 2 (b), the concavo-convex portion 4a for preventing the flow of the dew condensation water 5 is continuously formed on the outer heat exchanger side wall plate 4 surface. As shown in FIGS. 3 (a) and 3 (b), the condensed water 5 condensed on the surface of the uneven portion 4a on the surface of the heat exchanger side wall plate 4 is changed to the convex portion (mountain) of the continuous wave-shaped uneven portion 4a. Each time the vehicle gets over, the amount can be gradually reduced, and the momentum of the dew condensation water 5 can be suppressed.

For this reason, even when the lower portion of the heat exchanger 3 is configured to be retracted, similarly, the arrows A1 and A2 in FIG.
As shown in A2, the dew condensation water 5 flowing toward the receiving tray 6 can be made hard to be separated from the surface of the heat exchanger side wall plate 4, so that the dew condensation water 5 is heat-exchanged to the lowermost part of the heat exchanger side wall plate 4. The dew condensation water 5 can be made to adhere to the surface of the container side wall plate 4 and flow, so that the dew condensation water 5 does not easily fall to the outside of the tray 6.

In this embodiment, as shown in FIG. 1, when there are restrictions on the height and depth of the indoor unit in the housing 1, in order to improve the performance while maintaining the restrictions, a heat exchanger is used. The heat exchanger 3 is configured such that the surface area of the heat exchanger 3 is secured by bending the heat exchanger 3 in multiple stages. At this time,
If the dew condensation water 5 condensed on the surface of the heat exchanger side wall plate 4 is strong, the dew condensation water 5 jumps at the step portion of the heat exchanger 3 and drops as it is.

However, in this embodiment, FIG.
As shown in (b), since the uneven portion 4a for preventing the flow of the dew condensation water 5 is continuously formed on the surface of the outer heat exchanger side wall plate 4, the unevenness on the surface of the outer heat exchanger side wall plate 4 is formed. Part 4
As shown in FIGS. 3 (a) and 3 (b), the amount of the dew water 5 condensed on the surface a is gradually reduced every time when the condensed water 5 gets over the convex portion (mountain) of the continuous wave-shaped uneven portion 4a. It is possible to suppress the momentum of the dew water 5 flowing.

For this reason, even when the heat exchanger 3 is configured to be bent in multiple stages, similarly, as shown by arrows A1 and A2 in FIG. 5 can be made harder to separate from the surface of the heat exchanger side wall plate 4, so that the dew condensation water 5 at the step can be prevented from splashing,
The dripping of the dew condensation water 5 can be suppressed.

In the first embodiment, the concave and convex portions 4a formed on the surface of the heat exchanger side wall plate 4 are formed in the direction in which the dew water 5 flows, thereby suppressing the flow of the dew water 5 from flowing. The preferred embodiment has been described above, but the point is that dew condensation water 5
The uneven portion 4a may be formed in a direction that deviates from the direction in which the condensed water 5 flows, as long as it is a direction that can suppress the progress of the flow.

In the first embodiment, as the barrier for preventing the flow of the dew condensation water 5 from the flow of the dew condensation water 5, the concavo-convex portion 4a having the preferable pitch and height of the concavities and convexities is formed. Since it is sufficient that the uneven portion 4a can serve as a barrier for preventing the flow of the dew condensation water 5 from the flow of the dew condensation water 5, the uneven portion 4a may have a value other than the pitch of the unevenness and the height of the unevenness described above.
a may be configured.

In the first embodiment, the concavo-convex portion 4a having a continuous wave shape is formed on the surface of the outer heat exchanger side wall plate 4, so that the dew condensation water 5 condensed on the outer heat exchanger side wall plate 4 surface side is formed. Of the heat exchanger side wall plate 4 can be efficiently prevented from dropping from the surface side of the outer heat exchanger side wall plate 4 to the outside of the tray 12.
Uneven portions 4a capable of preventing the flow of the dew water 5 are selectively formed on the surface of the side wall plate 4 of the heat exchanger so that the dew water 5 condensed on the surface can be prevented from peeling off and falling to a portion other than the tray 12. It should just be done. For example, the heat exchanger side wall plate 4
An uneven portion 4a for preventing the flow of the dew condensation water 5 may be formed on the entire surface. In this case, the flow of the dew condensation water 5 condensing on the entire surface of the heat exchanger side wall plate 4 can be efficiently suppressed.

Embodiment 2 FIG. 5 and 6 are cross-sectional views of main parts showing the inside of an air conditioner according to Embodiment 2 of the present invention. 5 and 6, the same reference numerals as those in FIG. 1 denote the same or corresponding parts, 7 denotes an air outlet of the air conditioner main body 1, and 8 denotes an air passage provided in the housing 2 of the air conditioner main body 1. Reference numerals 9 and 10 denote air filters and fans, respectively, disposed in the housing 2, and reference numeral 11 denotes a design panel of the air conditioner main body 1.

In the first embodiment, a case has been described where the cross-sectional shape of the heat exchanger 3 is configured such that the lower portion thereof is set back and the shape is bent in multiple stages, but as in the present embodiment. As shown in FIG. 5, the cross-sectional shape of the heat exchanger 9 may be formed in a linear shape, or as shown in FIG. 6, the cross-sectional shape of the heat exchanger 9 may be formed in an inverted V shape. You may. The heat exchanger 3 shown in FIGS. 5 and 6 is formed by forming a continuous wave-shaped uneven portion 4a similar to that of FIG.

As shown in FIGS. 5 and 6, when the cross-sectional shape of the heat exchanger 9 is a straight line or an inverted V shape, if the dew of the dew condensation formed on the surface of the heat exchanger side wall plate 4 is strong, the dew condensation occurs. It is necessary to increase the depth of the tray 6 toward the design panel 11 in consideration of the fact that water splashes when leaving the surface of the heat exchanger side wall plate 4. However, in the present embodiment, as in the first embodiment, as shown in FIG. 2 (b), irregularities 4a for preventing the flow of dew water 5 are continuously formed on the surface of the heat exchanger side wall plate 4. Water condensed on the surface of the uneven portion 4a on the surface of the heat exchanger side wall plate 4
As shown in FIGS. 3A and 3B, the amount of the dew water 5 can be gradually reduced every time the vehicle passes over the convex portion (mountain) of the continuous wave-shaped uneven portion 4a. Can be suppressed. Moreover, since the depth of the tray 6 toward the design panel 11 can be reduced, the influence of the tray 6 on the depth of the indoor unit can be reduced.

In the first and second embodiments, FIG.
As shown in (b), the case where the uneven portions 4a formed on the surface of the heat exchanger side wall plate 4 are formed in a continuous wave shape and are preferable as a barrier shape for suppressing the flow of the dew condensation water 5 has been described. However, for example, as shown in FIG. 7, the uneven portion 4b formed on the surface of the heat exchanger side wall plate 4 may be formed by forming a continuous triangular shape. For example, as shown in FIG. The uneven portion 4c formed on the surface of the heat exchanger side wall plate 4 is
It may be formed in a continuous square shape. FIGS. 7 and 8
In the case of the continuous triangular shape / continuous quadrangular shape, as in the case of the continuous wave shape, the shape of the barrier for suppressing the flow of the dew condensation water 5 is also preferable.

Embodiment 3 FIG. 9 is a main part perspective view showing the inside of an air conditioner according to Embodiment 3 of the present invention. 9, the same reference numerals as those in FIG. 1 denote the same or corresponding parts, and 21 denotes a U-bend 22 arranged in the heat exchanger 3.
A cover disposed on the lower receiving tray 6 and for collecting dew water condensed on the U-bend 22 is provided.
It is, for example, a continuous wave-shaped uneven portion formed on one surface and formed in a direction in which the condensed water flows so as to prevent the flow of the condensed water flowing from the U-bend 22. The pitch and height of the concave and convex portions 21a are formed in the same dimensions as in the first embodiment.

When the dew water condensed on the U-bend 22 of the heat exchanger 3 reaches the surface of the continuous wave-shaped uneven portion 21 a formed on the surface of the cover 21, as in Embodiment 1, FIG.
As shown in (a) and (b), the concavo-convex portion 21 having a continuous wave shape is formed.
Every time it gets over the convex part (mountain) of a, its amount decreases sequentially.

The amount of the dew condensation water that has proceeded in the direction of flow of the projections gradually decreases each time it sequentially exceeds the projections of the continuously formed projections and depressions 21a. The momentum of flowing water is suppressed. Condensed water that has accumulated without exceeding the convex portion of the uneven portion 21a may increase in amount and flow out when newly formed condensed water is added or when newly added condensed water that exceeds the convex portion on the front side. become.

[0037] Similarly, the amount of the condensed water 5 which flows out gradually decreases each time the condensed water 5 successively passes over the convex portion of the concavo-convex portion 21a, thereby suppressing the flow of the condensed water. In the case where the dew water does not flow out without being newly added to the dew water that has accumulated, the dew water that has accumulated evaporates spontaneously without peeling off from the surface of the cover 21 and falling.

As described above, in the present embodiment, the concave and convex portions 21 for preventing the dew water flowing from the U-bend 22 from flowing.
a is formed continuously on the surface of the cover 21,
As shown in FIGS. 3A and 3B, the condensed water on the surface of the uneven portion 21a formed on the surface of the cover 21 is projected onto the convex portion (mountain) of the uneven portion 21a having a continuous wave shape, as shown in FIGS. ), The amount can be gradually reduced each time the vehicle gets over, and the flow of dew condensation water can be suppressed.

For this reason, it is possible to make it difficult for the dew water flowing toward the tray 6 to be separated from the surface of the cover 21, so that it is difficult for the dew water to fall outside the tray 6. Further, in the present embodiment, when the condensed water is collected in the receiving pan 6, the flow of the condensed water can be suppressed, so that the condensed water can be slowly dropped on the receiving pan 6, and the condensed water can be received in the receiving pan 6. It is hard to bounce on the surface, and it is possible to suppress the release to the outside of the tray 6.

Therefore, dew water can be efficiently collected in the tray 6 without using a conventional heat insulating material. In addition, since the conventionally required heat insulating material can be made unnecessary, it is possible to prevent an increase in the number of parts, work steps, and deterioration in recyclability due to the heat insulating material.

In the third embodiment, the case where the concave and convex portions 21a for preventing the flow of dew condensation water are formed on the surface of the cover 21 disposed below the U-bend 22 has been described. On the surface of a component other than the exchanger 3 that wants to prevent the flow of the condensed water, an uneven portion for preventing the flow of the condensed water may be formed. As in the third embodiment, the configuration may be such that the flow of dew water flowing from another component is prevented, or as in the first embodiment, the flow of dew water condensed on the component itself. May be prevented.

In the third embodiment, the case where the uneven portion 21a formed on the surface of the cover 21 is formed in the direction in which the condensed water flows is preferable in that the flow of the condensed water is suppressed. However, since it is only necessary that the direction is such that the flow of the condensed water can be suppressed, the uneven portion 21a may be formed in a direction deviated from the direction in which the dew water flows.

In the third embodiment, the concavo-convex portion 21a having the pitch of the concavo-convex and the height of the concavo-convex is preferably formed as a barrier for preventing the flow of the condensed water against the flow of the condensed water. Since the uneven portion 21a may serve as a barrier for preventing the flow of the condensed water with respect to the flow of the condensed water, the uneven portion 21a may have a value other than the pitch of the unevenness and the height of the unevenness described above.
May be configured.

In the third embodiment, as in the first embodiment, as shown in FIG. 2B, the uneven portion 21a formed on the surface of the cover 21 is formed in a continuous wave shape, and Although the preferred embodiment has been described as the shape of the barrier for suppressing the flow, as described above, the barrier may be formed in a continuous triangular shape as shown in FIG. 7, for example, or may be formed as shown in FIG. As described above, a continuous rectangular shape may be used. This continuous triangular shape / continuous square shape is also preferable as the shape of the barrier for suppressing the flow of dew water, as in the case of the continuous wave shape.

[0045]

According to the present invention, the concavities and convexities for preventing the flow of the dew condensation water are continuously provided on the surface of the heat exchanger side wall plate, so that the dew condensation on the surface of the heat exchange side wall plate is formed. The amount of the condensed water that has been condensed can be sequentially reduced every time the condensed water passes over the convex portion (mountain) of the uneven portion, and the flow of the condensed water can be suppressed. For this reason, the dew water flowing toward the tray can be made harder to separate from the surface of the side wall plate of the heat exchanger, so that it can be made harder to fall outside the tray. In addition, when the dew water is collected in the tray, the flow of the dew water can be suppressed, so that the dew water can be slowly dropped onto the tray, making it difficult for the dew water to bounce on the surface of the tray. Can be suppressed. Therefore, the dew water can be efficiently collected in the tray without attaching a heat insulating material to the surface of the heat exchanger side wall plate where the dew is formed.

In the air conditioner, the uneven portion is
By forming and configuring any of a continuous wave shape, a continuous triangular shape, and a continuous square shape, it is possible to obtain a preferable shape as a barrier shape for suppressing the flow of dew water condensed in the uneven portion. Thus, the flow of the dew water can be suppressed efficiently.

In the air conditioner, the cross-sectional shape of the heat exchanger may be any one of a shape in which the lower part of the front heat exchanger is retracted, a shape bent in multiple stages, a straight shape, and an inverted V shape. By forming and configuring, even if the cross-sectional shape is a heat exchanger in which the lower part of the front heat exchanger is recessed,
The retreating part of the lower part suppresses the flow of the dew condensation water, preventing the dew condensation from separating, and even if the heat exchanger has a cross-sectional shape that is bent in multiple stages, the dew condensation at that step By suppressing the flow of water, the separation of dew condensation water can be suppressed. Further, even in the case of a heat exchanger having a linear cross-sectional shape, the flow of the condensed water can be suppressed in the linear portion to prevent separation of the condensed water. Even in the case of the exchanger, the flow of the dew condensation water can be suppressed in the inverted V-shaped portion, and the separation of the dew condensation water can be suppressed.

According to the present invention, the concavo-convex portion for preventing the flow of the dew-water is continuously provided on the surface of the component to which the dew-water is attached and which is disposed in the housing other than the heat exchanger. Thereby, the amount of dew water condensed on the surface of the concavo-convex portion on the surface of the component can be sequentially reduced every time the condensed water passes over the convex portion (mountain) of the concavo-convex portion, and the flow of the condensed water can be suppressed. For this reason, for example, it is possible to make it difficult for the dew water flowing toward the tray to be separated from the surface of the component part, so that it is difficult to drop the water to the outside of the tray. Also, for example, when the dew water is collected in the receiving pan, since the flow of the dew water can be suppressed, the dew water can be slowly dropped on the receiving pan, so that the dew condensation water hardly splashes on the receiving pan surface, Release to the outside of the pan can be suppressed. Therefore, the dew water can be efficiently collected in the tray without attaching a heat insulating material to the surface of the component to be dewed.
