Abstract

PURPOSE:To eliminate a surplus load space caused by a dead space, provide an effective utilization of a calorie and prevent dew formation by a method wherein a partition plate for closing when a horizontal passage is opened is arranged in another passage communicating with a lower surface ceiling panel is arranged in such a way that it may be opened or closed and the partition plate is opened when the horizontal passage is closed. CONSTITUTION:Heat exchanged air is blown downwardly and an interior 59 is air conditioned through a discharging outlet 50. In case that a blowing port is varied in order to make a horizontal blowing, a closing plate 60 is removed, a duct 65 is connected to its blowing hole 62, is passed through a wall and then opened into the interior 69. A discharging panel 66 is provided with a discharging port 67 and in turn a downwardly directed passage is bent around a fulcrum of a hinge 55a so as to fold a partition plate 55 and to form a closed condition and to make a horizontal passage. An opening 63 which is opened under this condition may become an air sucking passage together with an air sucking port 64. In this way, the passage can easily be varied. Since a dead space may not be formed due to variation in passage, cold air may not be close and so dew may not be generated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a ceiling-embedded air conditioner.

[Conventional technology]

A conventional ceiling-embedded air conditioner has a blower, a heat exchanger, a drain pan, etc. arranged inside, and has a passageway that connects the air suction side of the blower and the air outlet side of the heat exchanger, and has a passageway connected to the lower ceiling panel. There is also one in which an opening communicating with the passage is provided, and the blowing direction 1c is completely downward and the horizontal direction VC is changed. However, when the blowing direction is changed to /R, a part of the passage before the change becomes a dead space, and this dead space also becomes a load space, which is required for extra heat tt', and is not the original load space. This causes heat loss for indoor air conditioning, and if cold air is trapped in dead spaces, the backflow of warm air from the aisles will cause Vci dew on the surrounding board surfaces, causing problems such as water droplets falling into the room. However, no consideration was given to the effective use of heat to the negative space or the occurrence of condensation. Further, a ceiling-embedded air conditioner related to these devices includes, for example, Utility Model Publication No. 60-2215.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into account the fact that cold air gets trapped in the dead space that is created when the outlet passage is changed, burdening the extra space. There were problems such as water falling into the room due to dew condensation.

It is an object of the present invention to effectively utilize heat and prevent condensation by eliminating excess load and waste due to dead spaces.

[Means for solving problems]

The above purpose is to provide the air outlet 91 passage of the heat exchanger by branching into a passage leading to the lower ceiling panel side and another passage opening into the room in the horizontal force direction. A partition plate that can be freely opened and closed is provided with a VC that closes the horizontal passage when the horizontal passage is opened, and when the horizontal passage is closed, the partition plate is opened and the passage is opened to the lower ceiling panel side. This is achieved by eliminating dead space through configuration.

[Effect]

When the entire outlet passageway of the heat exchanger is opened to the lower ceiling panel side, the partition plate is rotated via a hinge serving as a fulcrum and forms one side wall of the passageway. On the other hand, the opening of the horizontal passage is closed by a closing plate having frPA material. Also,
Conversely, when changing the passage in the horizontal direction, the rc removes the blocking plate and rotates and folds the partition plate to close the passage leading to the lower ceiling panel side. In this case, to the switched passage! There is no room for cold air to get stuck in the godet space. Therefore, no extra heat load is applied and no dew condensation occurs.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 and 3.

Reference numeral 41 denotes a main body case, and the end portion Y of the main body case is fixed to the upper ceiling 46A by means of a hanging port 44 and a nabut 45 via a seat 43 which is firmly seated. A bottom panel 42 has an air intake port 49 and an air discharge port 50, is formed integrally with the side wall of the main body case 41, and is attached to an opening 47 in the lower ceiling 46B. Reference numeral 48 is a cushioning material which is necessary for attaching the chisel face panel 42 in close contact with the lower ceiling 46B.

Reference numeral 51 denotes a blower that connects the main body case 41 via the mounting plate 54.
1/1m is completely redundant. A heat exchanger 52 is disposed on the discharge side of the blower 51, and a water receiver 111i53 is disposed below the heat exchanger 52. The 55rt partition is foldable with two hinges 55a, and is fixed to the main body base 41 so that it can rotate using one hinge as a fulcrum.

It is attached to the partition plate 55 with a 55-bar insulating material. 56t- is the blower room. 57II'i heat insulating material is attached to the inner wall surface of the main body case 41 on the downstream side of the heat exchanger 52.

58 is a heat insulating material attached to the back side of the water tray 53. 59 is the best. 60 is a closing plate covered with a heat insulating material.

In FIG. 1 described above, heat-exchanged desired air is blown downward from the discharge port 50 to control the inside of the room 59.

Next, FIG. 2 shows a case where the VC bath opening is bent horizontally so that the outlet is lowered. That is, the closing plate 60 is removed, the air outlet hole 62 is connected to the VC duct 65, and is opened into the room 69 through the wall. 6 discharge ports with 66 discharge panels
7 is provided. On the other hand, the passage in the downward direction is provided by a partition plate 55.
is bent using the VC hinge 55a as a fulcrum to close it and form a horizontal passage. Further, the opening 63 thus opened becomes an air suction passage together with the air suction port 64.

In this way, you can easily change the route. Further, since no ted space is formed due to the change of the passage, cold air will not be trapped, and therefore no connection will occur.

〔Effect of the invention〕

According to the present invention Vζ, it is possible to eliminate dead space, effectively utilize the amount of heat, and prevent dew condensation.
