BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner drain pipe testing apparatus for detecting water leakage.

[0002]

2. Description of the Related Art As an air conditioner, there is a ceiling-embedded package type air conditioner (hereinafter referred to as an air conditioner) which is directly embedded in a ceiling in order to omit an installation space in an air conditioner machine room or a floor. In such an air conditioner, a cooler and a blower fan will be embedded in the ceiling,
The air sucked from the vicinity of the ceiling is heat-exchanged by passing through the cooler, becomes a low temperature, and is blown directly into the room.
By the way, when the air is cooled to the saturation temperature or lower when passing through the cooler, the water contained in the air is condensed in the cooler. This condensed water is collected in the drain pan in the air conditioner,
It is led to the drainage connection port provided in the drain pan. The drainage connection port is projected to the outside of the air conditioner in a tubular shape, and the projected drainage connection port is a pipe made of vinyl chloride, which is a drainage pipe, or
Flexible piping is connected. The connection between the drainage connection port and the drainage pipe is usually not permanently fixed considering the relocation and maintenance of the air conditioner. Therefore, the drainage pipe is securely fixed to the drainage connection port by a hose band or the like, and the watertightness is maintained. Further, since the condensed water has a low temperature, if the temperature difference from the outside air temperature is large, dew condensation will occur on the outer surfaces of the drainage connection port and the drainage pipe. Therefore, a heat insulating material is wound around the drainage connection port and the drainage pipe to prevent dew condensation so that the condensed water does not wet the ceiling. In this way, the condensed water condensed in the cooler is collected in the drain pan, and the drainage connection port,
It is designed to be drained to the outside through the drain pipe.

[0003]

Conventionally, a drainage pipe is connected to a drainage connection port protruding from an air conditioner, and the drainage pipe is fixed by a hose band so as to maintain watertightness. Therefore, after the drainage pipe is fixed, the water flow test to check for water leakage cannot be performed, and if the test is inevitable, the fixed drainage pipe must be removed again, which is extremely inconvenient. At the same time, the frequent connection work at the connection portion has been a factor in causing water leakage. Regarding this, it would be good if the water flow test can always be performed before connecting the drainage pipes, but at the site of new construction, etc., the primary side drainage pipe construction may not be completed when connecting the drainage pipes. In such a case, the water flow test cannot be performed, and therefore, if the drainage pipe construction is performed after waiting for the primary side drainage pipe construction, the construction process will be significantly restricted. Further, even if water can be passed by removing the drain pipe, the test at the connection part of the drainage connection port cannot be performed, and the place where the highest possibility of water leakage occurs is not tested. Furthermore, this can be said not only in the water passage test at the time of construction completion, but also in the trial run before the cooling season, in order to perform water passage, the drainage pipe must be pulled out from the drainage connection port, Then, as described above, even if water could be passed from the drain pipe inlet, the place where the highest possibility of water leakage occurred was not tested. Under the circumstances described above, the water flow test after the construction and before the cooling season is rarely conducted. Therefore, it is possible to prevent a water leakage accident due to poor construction or aged pipe clogging. If water leaks once, the interior members (ceiling board, etc.) must be wetted and all wet ceiling boards, etc. must be replaced to prevent stains due to mold, etc. There was a risk that repair costs would be incurred.

The present invention has been made in view of the above circumstances, and provides an air conditioner drain pipe test apparatus capable of easily conducting a water passage test even in a state in which a drain connection port and a drain pipe are connected. The purpose is to prevent water leakage due to poor construction or aged drainage pipe clogging, and to prevent loss to interior components due to water leakage accidents.

[0005]

An air conditioner drain pipe testing device according to the present invention for achieving the above object is an air conditioner drain pipe testing device for detecting leakage of drainage pipe,
An opening is formed in a tubular drainage connection port protruding from the air conditioner, and a plug that seals the opening is detachably provided, and when the plug is removed, a funnel shape that can be attached to the opening. It is characterized by having a water supply port.

[0006]

[Function] Remove the plug of the opening formed in the drainage connection port, attach the water supply port to the opening, pour water for the water flow test from the water supply port, and remove the drainage pipe from the drainage connection port. It is possible to pass water without it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of an air conditioner drain pipe testing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing an air conditioner drain pipe testing device according to the present invention. A ceiling-embedded package type air conditioner (hereinafter referred to as an air conditioner) 1 is embedded in the ceiling, and its lower surface is flush with the ceiling board 3. On the side surface of the air conditioner 1, a short tubular drainage connection port 5 is orthogonal to the vertical direction (parallel to the ceiling board 3).
Condensed water condensed by the cooler and collected in the drain pan is drained from the drainage connection port 5. A drain pipe 7 is connected to the outer periphery of the drain connection port 5, and the drain pipe 7 is fixed to the drain connection port 5 by a hose band (not shown). Therefore, the condensed water drained from the drainage connection port 5 is guided from the inside of the ceiling to the primary side drainage pipe via the drainage pipe 7.

By the way, an opening 9 is provided between the air conditioner 1 and the drain pipe 7 on the outer periphery of the upper portion of the drainage connection port 5 projecting from the air conditioner 1. The opening 9 has a funnel-shaped water supply port 1
1 is attached, and the water supply port 11 is detachable from the opening 9. Since the opening 9 is provided between the air conditioner 1 and the drainage pipe 7, it is located upstream of the connection portion a between the drainage connection port 5 and the drainage pipe 7. Therefore, the water supply port 11 attached to the opening 9
In addition, when water is poured from the water supply device 13 or the like, the water passes through the connection portion a and flows to the drain pipe 7. Normal time,
The opening 9 is provided with a plug (not shown) capable of maintaining water-tightness and air-tightness, and the plugged opening 9 is further covered with a heat insulating material.

In the air conditioner drain pipe testing apparatus constructed as described above, when the water flow test is performed at the time of completion of construction or at the time of trial operation before the cooling season, first, the heat insulating material of the drainage connection port 5 is removed. Then, the plug is removed, and the water inlet 1 is provided at the opening 9.
1 is attached. After the water inlet 11 is attached to the opening 9, water is poured into the water inlet 11 by the water supplier 13 or the like,
Water passes from the air conditioner 1 side through the connection portion a, flows through the drain pipe 7, and is drained to the primary side drain pipe. Therefore, water is passed only by removing the plug and attaching the water supply port 11 to the opening 9, and the water passage test can be easily performed at any time without removing the drain pipe 7. In addition, since water passes through the connecting portion a, the location where the possibility of water leakage is highest is tested.

According to the air conditioner drain pipe testing apparatus described above,
Since the water supply port 11 is attached by removing the plug, the water flow test can be easily performed at any time without removing the drain pipe 7 from the drain connection port 5.

Further, since the water supply port 11 is detachably provided in the opening 9 and the opening 9 is normally closed with a plug,
During normal operation of the air conditioner 1, the protrusions from the drainage connection port 5 are eliminated, and the insulating material can be easily and reliably coated to prevent dew condensation.

In addition, the drainage connection 5 is generally an air conditioner 1.
Since it communicates with the internal chamber, a pressure difference may occur inside, but since the opening 9 is provided with a plug that can maintain watertightness / airtightness, there is no blowout or intake from the opening 9 During normal operation of the machine 1, there is no fear of lowering the blowing efficiency.

In the air conditioner drain pipe test apparatus according to this embodiment, the drainage connection port 5 is described as an example in which it is projected from the side surface of the air conditioner 1 in a direction orthogonal to the vertical direction. 5 may be provided so as to project in the vertical direction. In this case, the water supply port 11 can be inclined and inserted into the drainage connection port 5 through the opening 9.

[0014]

As described in detail above, according to the air conditioner drain pipe testing apparatus of the present invention, an opening is formed in the tubular drainage connection port, and a plug for sealing the opening is removable from the opening. Since it has a funnel-shaped water supply port that can be attached to the opening when the plug is removed, the drain pipe can be removed by removing the opening plug, attaching the water supply port to the opening, and pouring water from the water supply port. Water can be passed through without removing it from the drainage connection port. As a result, the water flow test can be easily performed even in the state where the drainage connection port and the drainage pipe are connected, resulting in poor construction,
Alternatively, it is possible to prevent water leakage due to aged clogging of the drainage pipe, and prevent loss to the interior members and the like due to a water leakage accident.
