Description

Air conditioning.

The present invention relates to a air conditioner.

Figure 8 is a main sectional view of a conventional air conditioner, for example, described in the document JP-U-4-68921. The Figures 9 and 10 are main side views showing the internal structure of the conventional air conditioner. In the Figures 9 to 10, reference number 101 designates a air conditioner itself; 102, the accommodation of body 101 of the air conditioner; 103, a decorative panel; 104, a heat exchanger side wall plate; he 105, a heat insulating material; the 106, an air outlet; the 107 a passage for air circulation; 108, a air filter; 109, a heat exchanger; the 110, a fan; 111, a wind direction plate; and 112, a collector Incidentally, the surface of the plate 104 of Side wall of heat exchanger is flat.

In the case of the structure above mentioned, as shown in Figure 9, dew drops 115 formed by condensation on the flat surface of the wall of side plate 104 of the heat exchanger circulate down on the surface of the side wall plate 104 of the heat exchanger. However, in a staggered part of the side plate wall 104 of heat exchanger, drops dew 115 are frequently suitable for ceasing to circulate on the surface of the side wall plate 194 of the exchanger of heat and fall down to the outside of manifold 112.

If the dew drops fell outside the collector 112 in this way, there was a case in which the drops of dew 115 escaped outside housing 102 of the air conditioner itself 101. In order to prevent dew drops 115 from falling downwards to the outside of manifold 112, conventionally, as shown in Figure 10, heat insulating material 105 was applied to the surface of the side wall plate 104 of the heat exchanger to prevent that exuded the surface of the side wall plate 104 of the heat exchanger.

However, the air conditioner conventional as described above was designed in such a way so that the heat insulating material 105 was applied to the surface of the side wall plate 104 of the heat exchanger heat in order to prevent it from oozing the surface of the plate side wall 104 of the heat exchanger. According to that, the problem has arisen that the number of the parties components and the number of operations increased, and performance of the recirculation deteriorated.

Summary of the invention

An object of the present invention is to provide a air conditioner in which dew drops can be collect positively without applying any heat insulating material Nowhere to exude. The object is achieved by air conditioners specified in claims 1 to Four.

Optimal way of carrying out the invention

Embodiments of the following are described present invention with reference to the drawings.

Realization one

Figure 1 is a main view in perspective showing the inside of an air conditioner Embodiment 1 in accordance with the present invention. Figure 2 is a side view of an exchanger side wall plate of heat on whose surface a rough part has formed continuously wavy Figures 3 (a) and 3 (b) are views of enlarged scale showing the continuously wavy rough part formed on the surface of the side wall plate of heat exchanger shown in Figure 2. Figure 4 is a main side view showing the inside of the conditioner of air shown in Figure 1. Figure 2 shows the plate side wall heat exchanger on which it has formed a continuously wavy rough part.

In Figures 1 to 4, the reference number 1 designates an air conditioner itself; the 2, the air conditioner housing itself; and 3, a heat exchanger installed in housing 2. Number 4 reference designates an exchanger side wall plate of heat formed on the side wall of the heat exchanger 3; the 4th, a rough part that has, for example, a shape continuously wavy, and that has formed on the surface of the side wall plate 4 of the heat exchanger in one direction in which dew drops 5 circulate, in order to restrict the circulation of dew drops 5; the 6, a manifold arranged under heat exchanger 3 for collect dew drops 5 formed on the wall plate side 4 of the heat exchanger.

The roughly wavy rough part 4a formed on the surface of the side wall part 4 of the heat exchanger has been shaped in the direction in which dew drops 5 circulate, such that the passage of irregularities be adjusted to be, for example, 6 mm, and the height of irregularities is adjusted to be, for example, 1 mm The rough part 4a formed on the surface of the plate 4 of side wall of the heat exchanger with said pitch and height is provided to serve as an obstacle to the circulation of the drops dew 5 in order to restrict the circulation of droplets dew 5.

Dew drops 5 formed on the outer surface of the exchanger side wall plate 4  of heat are gradually reduced in quantity whenever the dew drops 5 become above an elevated area (highlight) of the roughly undulating rough part 4a, as shown in Figures 3 (a) and 3 (b). Figure 3 (a) shows the state in which the dew drop 5 formed in the rough part 4a has not yet exceeded the protrusion of the rough part 4a, and Figure 3 (b) presents the state in which the dew drop 5 formed in the rough part 4a has exceeded a highlight of rough part 4a and has separated into two parts in front and behind the shoulder of such so that the amount of dew drops in the direction of travel

The amount of dew drops 5 is reduced gradually whenever a drop of dew 5 exceeds a protrusion of the rough part 4a formed continuously. As a result, the force Circulation of dew drops is restricted. For him on the contrary, with respect to the retained dew drop 5 that has not exceeded a roughness of the rough part 4a, if it is formed again another drop of dew and joins the retained dew drop 5, or if another  dew drop exceeds the forehead and joins the drop of retained dew 5, increases the amount of dew drops retained 5 such that the dew drops retained 5 They start to flow.

Then, in the same way, the amount of 5 dew drops that circulate now gradually reduce always that the dew drops exceed a protrusion of the rough part 4a. By therefore, the circulation force of the dew drops is restricted. If the retained dew drop 5 is not joined again by a drop of dew 5, dew drops 5 will not start to flow. In that case, retained dew drops 5 evaporate due to natural causes without separate or fall from the surface of the side wall plate 4 of the heat exchanger.

In this embodiment, the rough part 4a serves for the circulation of dew drops 5 and therefore that continuously form on the outer surface of the plate 4 of side wall of the heat exchanger. As a result, you can gradually reduce the amount of dew drops formed on the surface of the rough part 4a of the side wall plate 4 of the heat exchanger whenever dew drops 5 exceed a raised area (protrusion) of the continuously waved rough part 4a, as shown in Figures 3 (a) and 3 (b). In this way, the force of circulation of dew drops can be restricted 5.

As a result, as shown by the arrows A1 and A2 in Figure 4, you can make the dew drop 5 have difficulty moving to collector 6 to separate of the surface of the exchanger side wall plate 4 of heat and therefore it is difficult for them to fall outside the manifold 6. In addition, in this embodiment, the circulation force of dew drops 5 can be restricted when the drops of dew are collected in the collector 6. Accordingly, the drops of dew 5 can fall to collector 6 so slowly that the drops of dew have difficulty spreading and splashing on the surface of the manifold 6. Therefore, it can be restricted that dew drops 5 are discharged outside the collector 6.

Therefore, dew drops can be collected 5 in manifold 6 efficiently without applying any material heat insulator to the surface of the side wall plate 4 of the heat exchanger that exudes. Additionally, as has been omitted the heat insulating material that had been required in the prior art, it is possible to prevent the number of parts and the number of component operation processes and that impair recirculation performance due to the presence of said heat insulating material.

Additionally, in this embodiment, as has been shown in Figure 1, in the case where the indoor unit contained in accommodation 2 have a limit as to depth and height, heat exchanger 3 is configured back and folds at the bottom of it to ensure thereby the required surface area of the heat exchanger heat 3 in order to improve performance at the same time as keep the limit. In this way, the manifold 6 can be installed very deep inside from the end face of the plate 4 of side wall of heat exchanger.

Under these conditions, if the force of the drops of dew formed on the side wall plate 4 of the heat exchanger had a certain intensity, the drops of dew 5 would separate and fall from the surface of the part adjusted back of the bottom of the exchanger heat 3. However, in this embodiment, as shown in the Figure 2, as the rough part 4a that serves to restrict the dew drop circulation 5 is continuously formed on the outer surface of the side wall plate 4 of the heat exchanger, you can gradually reduce the amount of dew drops formed on the surface of the rough part 4a on the outer surface of the side wall plate 4 of the heat exchanger whenever dew drops 5 exceed a raised area (protrusion) of the continuously waved rough part 4a as shown in Figures 3 (a) and 3 (b). Therefore, it can restrict the circulation force of dew drops 5.

In accordance with the above, still in the case in which the heat exchanger 3 has been designed to set it back at the bottom of it, you can make it difficult for dew drops 5 to circulate towards the manifold 6 separate from the surface of the wall plate 4 side of heat exchanger as shown with arrows A1 and A2 in Figure 4. As a result, you can make the dew drops flow down to the bottom of plate 4 side wall heat exchanger while they are adhering to the surface of the side wall plate 4 of the heat exchanger, so that it can be made difficult that the dew drops 5 fall outside the collector 6.

Additionally, in this embodiment, as has been shown in Figure 1, in the case where the indoor unit contained in housing 2 have a height limit and depth, the heat exchanger is designed to be layer in multiple stages to ensure the area of necessary surface of heat exchanger 3 in order to improve performance while maintaining the limit. In these conditions, if the force of dew drops 5 formed in the surface of the side wall plate 4 of the exchanger heat was intense, dew drops 5 on each stepped part of heat exchanger 3 would splash and fall down, As is the case.

However, in this embodiment, as has been shown in Figure 2, as the rough part 4a to restrict circulating dew drops 5 has continuously formed over the outer surface of the side wall plate 4 of the heat exchanger, you can gradually reduce the amount of dew drops formed on the surface of the rough part on the outer surface of the side wall plate 4 of the heat exchanger whenever dew drops 5 exceed a raised area (protrusion) of the rough part 4a continuously wavy as shown in Figures 3 (a) and 3 (b). In this way, the force of circulation of dew drops can be restricted 5.

In accordance with the above, even in the case in that the heat exchanger 3 is designed to bend in multiple stages, similarly it can be made difficult for dew drops 5 flowing to manifold 6 separate from the surface of the side wall plate 4 of the exchanger heat as shown by arrows A1 and A2 in Figure 4. As a result, it can be restricted to splash the drops of dew 5 of the stepped part and accordingly, can be limited that dew drops fall down 5.

In Embodiment 1, the rough part 4a formed on the surface of the side wall plate 4 of the heat exchanger has formed in the direction in which dew drops flow 5. However, the rough part 4a is could form in any direction by which you can restrict the circulation of dew drops 5.

In Embodiment 1, the rough part 4a has been designed to conform so that it has irregularities with a preferable step and a preferable height to serve as an obstacle to the circulation of dew drops 5 in order to prevent dew drops flow 5. However, in summary, to the part rough 4a is only required to be able to become an obstacle to the circulation of dew drops in order to prevent dew drops from flowing 5 Accordingly, the rough part 4a could be shaped to have values in step irregularity and irregularity height different from preferable values mentioned above.

The description previously made of the Embodiment 1, on the case in which it was preferable in the aspect in which the continuously waved rough part 4a formed on the outer surface of the side wall plate 4 of the heat exchanger, so that it could be prevented from efficient way that dew drops 5 formed on the surface external plate 4 side wall heat exchanger fall from the outer surface of the side wall plate 4 from heat exchanger to outside of manifold 6. Without However, in summary, to the rough part 4a that can restrict that Dewdrops 5 circulate only required to be selectively conforming to the surface of the wall plate 4 side of the heat exchanger so that you can prevent dew drops 5 formed on the surface of the side wall plate 4 of the heat exchanger separate from the same and fall to a place that is outside the collector 6. For example, the rough part 4a that serves to restrict that dew drops flow 5 could be designed to be conform over the entire surface of the plate 4 of side wall of the heat exchanger. In this case, you can efficiently restrict the circulation of dew drops formed on the entire surface of the wall plate 4 side of heat exchanger.

Incidentally, the description has been made above on the case in which the rough part 4a formed in the surface of the side wall plate 4 of the exchanger heat has been shaped so that it has a shape continuously wavy that was preferable as the shape of an obstacle to the circulation of dew drops 5 as shown in the Figure 3. However, by way of example, a rough part 4b formed on the surface of the side wall plate 4 of the heat exchanger could be designed to conform to a continuous triangular shape as shown in Figure 5. or a rough part 4c formed on the surface of the wall plate 4 Heat exchanger side could be designed to conform in a continuous square shape as shown in Figure 6. Additionally, the combination is also preferable. of these triangular and square continuous forms as the form for constitute an obstacle to the circulation of dew drops 5 of the same way as the continuously wavy shape.

Realization 2

Figure 7 is a main view in perspective showing the inside of an air conditioner Embodiment 2 in accordance with the present invention. The number 21 of reference designates a cover that is disposed above a manifold 6 and that is installed below a few U-elbows arranged in a heat exchanger 3, such that the lid collects the dew drops formed on the U elbows 22. The reference number 21a designates a rough part formed on the surface of the lid 21 in the direction in which the dew drops from the elbows in U 22, in order to restrict the dew drops circulation. The rough part 21a has, for example, a continuously wavy form. Incidentally, the rough part 21a is formed to have dimensions of step and height similar to those of Embodiment 1.

When a dew drop formed in one of the U-elbows 22 of heat exchanger 3 reaches the surface of the continuously waved rough part 21a formed in the surface of the lid 21, the amount of dew drops is reduce gradually whenever dew drops exceed an area raised (highlight) of the continuously waved rough part 21a as shown in Figures 3 (a) and 3 (b) in the same way as in Embodiment 1.

The amount of dew drops 5 is reduced gradually whenever the dew drops exceed a highlight of the rough part 21a formed continuously. How result, the circulation force of the dew drops is restrict. On the other hand, if another drop of dew recently formed or another drop of dew that has not exceeded the shoulder joins a retained dew drop that has not exceeded a shoulder of the part rough 21a, increases the amount of retained dew drops To flow again.

Then, in the same way, the amount of dew drops 5 that begin to flow is reduced in that way gradually whenever the dew drops exceed the Next highlight of the rough part 21a. Therefore, it is restricted the circulation force of dew drops. When to the drops retained dew drops do not join them again dew drops, retained dew drops will not start to flow. In that case, dew drops evaporate for natural causes without separating or fall off the surface of the lid 21.

In this embodiment, the rough part 21a that serves to restrict the circulation of dew drops that flow from the elbows U has been formed continuously in the surface of the lid 21 in the manner mentioned above. As a result, the amount of drops can be gradually reduced of dew formed on the surface of the rough part 21a in the surface of the lid 21 provided that the dew drops exceed a raised area (protrusion) of the rough part 21a continuously corrugated, as shown in Figures 3 (a) and 3 (b), of it so that in Embodiment 1. Therefore, the circulation force of dew drops.

As a result, it can be made difficult that the dew drops that circulate towards the manifold 6 separate of the surface of the lid 21 and therefore it is difficult for fall outside the collector 6. Additionally, in this embodiment, the circulation force of the dew drops when dew drops are collected in the collector 6. Accordingly, dew drops may fall to the collector 6 so slowly that it is difficult for dew drops to splash on the surface of the collector 6. That way, you can restrict that dew drops are discharged to the outside of manifold 6.

Therefore, dew drops can be collected efficiently in manifold 6 without using said insulating material which was conventionally used. Additionally, how can you omit any heat insulating material that is required conventionally, it is possible to prevent the number of component parts and the number of operating procedures and that the recirculation performance deteriorates due to the presence of said heat insulating material.

Incidentally, the above description has been fact about Embodiment 2 about the case in which the party rough 21a intended to restrict the circulation of drops of dew is designed to form on the surface of the lid 21 installed below U elbows 22. However, a part rough to restrict dew drops from circulating you could form on the surface of a constituent part other than a heat exchanger 3, in which the constituent part has been designed to restrict the circulation of dew drops. Such rough part could be designed to restrict circulation of dew drops flowing from any other part that the constituent part shown in Embodiment 3 or for restrict the circulation of dew drops formed in the own constituent part as shown in the Claim one.

In Embodiment 2, the rough part 21a formed on the surface of the lid 21 has been formed in the direction in the dew drops flowing 5. However, the rough part 21a is could form in any direction by which you can positively restrict the circulation of dew drops 5.

According to Embodiment 2, the rough part 21a has been formed to have said irregularity step and said height of irregularity, preferably, as an obstacle to the circulation of dew drops in order to prevent them from circulating dew drops However, in summary, to the rough part 21a you are only required to be able to become a obstacle in order to prevent dew drops from circulating, and therefore the rough part 21a could be formed to have in step of irregularity and irregularity height values different from the above mentioned values.

The description has been made previously on the case where the rough part 21a formed on the surface  of the lid 21 has been shaped to have a continuous shape wavy that was preferable as the way to be an obstacle to the circulation of dew drops as shown in the Figure 2, in the same way as in Embodiment 1. However, as stated above, said rough part 21a could conform to a continuous triangular shape, for example, as shown in Figure 5 or in a continuous square shape, by example, as shown in Figure 6. In addition, the combination of these continuous triangular and square shapes is also preferable as the way to constitute an obstacle to the dew drops circulation, similar to the case of the form continuously wavy
