Description

  The present invention relates to a socket provided in an air conditioner for performing indoor air conditioning, an air conditioner including the socket, and a method of installing the air conditioner.

  An air conditioner installed in a factory, an office building, a home, etc. and performing indoor air conditioning is known. The air conditioner is composed of an outdoor unit having a compressor and the like and an indoor unit having an indoor fan and the like, and air whose temperature and humidity are adjusted is supplied from the indoor unit to the room.

  The indoor air of the air conditioner is taken in the indoor air, and this air is blown out into the room after passing through the heat exchanger. Here, when the room air is cooled by the heat exchanger during the cooling operation, the water vapor contained in the air is condensed to generate drain water. For this reason, a drain pan for storing the drain water and a drainage pump for draining drain water from the drain pan are provided in the air conditioner.

  Since drain water is stored in the drain pan, install the air conditioner at the correct design position (for example, the drain pan is placed on a horizontal surface or the drain pan is inclined at a predetermined angle from the horizontal surface). Otherwise, water may leak from the drain pan, which is not preferable. Therefore, in the air conditioner of Patent Document 1, the rising pipe is separately provided so that the gradient of the drain pan (water receiver) with respect to the horizontal surface can be confirmed, and the drain pan can be correctly installed.

Japanese Patent Application Laid-Open No. 7-83461

However, in the case of separately providing a structure for detecting the slope of the drain pan as in the air conditioner of Patent Document 1, there arises a problem that cost increases and an installation space is required.
Also, conventionally, the slope of the drain pan has been confirmed using a level or hose with water, etc. For example, when installing an indoor unit in a space under the ceiling, the working space is small and the level or hose with water etc. There is a problem that the operation of checking the slope of the drain pan to be used requires much time and effort.

  The present invention has been made to solve the above problems, and a socket and an air conditioner capable of easily adjusting the installation position of the drain pan while suppressing the cost, and a method of installing the air conditioner using the socket I will provide a.

In order to solve the above-mentioned subject, the present invention proposes the following means.
A socket according to a first aspect of the present invention is an indoor fan that blows out air, a heat exchanger that exchanges heat with the air blown out from the indoor fan, and stores drain water condensed by the heat exchanger Provided in an air conditioner comprising a drain pan for draining, a drainage pump for draining the drain water stored in the drain pan, and a housing for housing the indoor fan, the heat exchanger, the drain pan, and the drainage pump; A socket interposed between the drainage pump and the drainage pipe, the socket being attached to the housing and having a tubular shape extending to the outside of the housing, and formed of a light transmitting material, It has an outer cylindrical portion connectable to the drainage pipe line, and the outer cylindrical portion is mounted on the housing on the outer surface of the outer cylindrical portion, and the drain pan is installed at a predetermined position. The State and the horizontal line portion is provided extending in the horizontal direction, the horizontal line portion at different positions the outer surface of the outer tubular section, and are arranged in parallel in pairs in the position of the same height.

According to such a socket, if the drain pan is not installed at a predetermined position (in the horizontal plane or at a position inclined with respect to the horizontal plane and the drain pan is properly installed in design), The horizontal lines do not extend in the horizontal direction, but are arranged to extend in a direction inclined with respect to the horizontal direction. Under the present circumstances, since the outer side cylinder part has a light transmittance, it is a liquid surface, for example, when the outer side cylinder part is seen from the outside in the state which liquids, such as drain water drawn up with a drainage pump, stagnated in a socket. It can be confirmed that the and the horizontal line do not coincide or are not parallel. Therefore, the inclination of the drain pan is adjusted by adjusting the slope of the air conditioner (indoor unit) so that the liquid level and the horizontal part coincide or become parallel, and the drain pan is placed at the correct installation position Thus, it becomes possible to adjust the position of the drain pan.
Furthermore, since the socket is for connecting the drainage pump and the drainage pipe, this socket is originally required for the air conditioner. In the present invention, the drain pan can be installed at a predetermined position only by providing the horizontal line portion in the socket. That is, the position adjustment of the drain pan can be performed without newly providing an additional member to the air conditioner.
Further, the horizontal line portion is provided in a pair at the same height position in the outer cylindrical portion, so that when the outer cylindrical portion is viewed from the outside, the liquid level in the outer cylindrical portion is parallel to the horizontal line portion. Even if the liquid level and the horizontal line portion are different in position in the height direction, the drain pan is inclined in the direction orthogonal to the extending direction of the horizontal line portion. As a result, not only the inclination of the drain pan in the direction in which the horizontal portion extends, but also the inclination of the drain pan in the direction orthogonal to the horizontal portion can be confirmed, and more precisely, the drain pan is disposed and installed at a predetermined correct installation position. Is possible.

  As described above, since the lower end portion of the inner cylindrical portion is positioned above the lower end portion of the outer cylindrical portion, the liquid is easily retained inside the outer cylindrical portion below the lower end portion of the inner cylindrical portion. That is, it is possible to suppress the liquid from flowing out from the outer cylindrical portion by the step formed between the inner cylindrical portion and the outer cylindrical portion. Therefore, the position of the liquid surface and the position of the horizontal line portion can be compared more reliably, and the drain pan can be disposed and installed at a predetermined correct installation position.

  In the socket according to the third aspect of the present invention, the outer cylindrical portion in the second aspect has a cylindrical shape, the inner cylindrical portion has a cylindrical shape smaller in diameter than the outer cylindrical portion, and The central axis of the cylindrical portion and the central axis of the inner cylindrical portion may coincide with or intersect with each other.

  In such a socket, the lower end portion of the inner cylindrical portion is positioned above the lower end portion of the outer cylindrical portion, and the liquid between the lower end portion of the inner cylindrical portion and the lower end of the outer cylindrical portion in the socket Is likely to stagnate. Therefore, the position of the liquid surface and the position of the horizontal line can be compared more reliably, and the drain pan can be disposed and installed at a predetermined correct installation position.

  According to such an air conditioner, by providing the above-mentioned socket, for example, while the liquid such as drain water sucked up by the drainage pump stays in the socket, the liquid surface and the horizontal line portion are parallel By doing this, it is possible to place the drain pan in a predetermined correct installation position. Furthermore, since the drain pan can be installed at a predetermined position only by providing the horizontal line portion in the socket, the position adjustment of the drain pan can be performed without providing an additional member.

In the air conditioner installation method according to the fifth aspect of the present invention, an indoor fan blowing out air, a heat exchanger that exchanges heat with the air blown out from the indoor fan, and the heat exchanger Drain pan for storing drain water condensed in the above, a drainage pump for draining the drainage water stored in the drain pan, a case for housing the indoor fan, the heat exchanger, the drain pan and the drainage pump, and the drainage A method of installing an air conditioner comprising a socket interposed between a connection conduit extending from a pump and a drainage conduit, the cylinder being attached to the housing and extending outside the housing And a step of retaining the liquid inside the outer cylindrical portion of the socket which is formed of a light-transmissive material and can be connected to the drainage pipe, and the liquid level of the liquid inside the outer cylindrical portion , An angle with a horizontal line portion which is provided on the outer surface of the outer cylindrical portion and extends horizontally in a state where the outer cylindrical portion is attached to the housing and in a state where the housing is installed at a predetermined position The process of confirming the deviation, and the process of adjusting the position of the drain pan so as to eliminate the angular deviation between the horizontal line portion and the liquid surface of the liquid, and installing the air conditioner.

  According to the installation method of such an air conditioner, by installing the air conditioner using a socket provided with a horizontal portion, for example, a state in which liquid such as drain water sucked up by a drainage pump is retained in the socket Then, by making the liquid level and the horizontal line portion parallel, the angular deviation can be eliminated, and the drain pan can be adjusted to the correct installation position. Furthermore, since the drain pan can be installed at a predetermined position only by providing the horizontal line portion in the socket, the position adjustment of the drain pan can be performed without newly providing an additional member to the air conditioner.

  According to the above installation method of the socket, the air conditioner, and the air conditioner, the installation position of the drain pan can be easily adjusted while suppressing the cost by providing the horizontal line portion in the outer cylindrical portion of the socket.

Next, the socket 21 will be described in detail.
As shown in FIG. 1 and FIG. 2, the socket 21 is a drainage pipe 16 that is attached from the outer surface to the housing 19 and extends from the drainage pump 16. It is interposed between the piping (drainage pipe line) 25. The socket 21 is formed of a light transmitting material (resin or the like) and is transparent or translucent.

  As shown in FIG. 3, the socket 21 is integrally provided at an end portion of the outer cylindrical portion 31 having a cylindrical shape extending to the outside of the housing 19 and an end portion of the outer cylindrical portion 31 on the housing 19 side. And an inner cylindrical portion 33 which extends from the flange portion 32 to the opposite side to the outer cylindrical portion 31 and penetrates the housing 19.

  The inner cylindrical portion 33 has a cylindrical shape, extends inside the housing 19, and is fitted into the connection piping 17 provided on the drainage pump 16 inside the housing 19.

  The flange portion 32 is provided in contact with the outer surface of the housing 19 at a corner 19a of the housing 19 as shown in FIG. In the present embodiment, the corner 19a of the housing 19 has a C-chamfered shape, and the surface of the flange 32 is in contact with the chamfered portion. As shown in FIG. 4, a through hole 32 a having the same diameter as the inner diameter of the inner cylindrical portion 33 is formed in the flange portion 32 so as to be continuous with the inner surface of the inner cylindrical portion 33.

  The outer cylindrical portion 31 has a cylindrical shape and is connected to the drainage pipe 25 by being fitted into the drainage pipe 25 for draining the drain water D, and the drainage pipe 25 and the inner side of the inner cylindrical portion 33 It is in communication. Further, the outer cylindrical portion 31 is fitted in the drainage pipe 25 up to the middle position in the extending direction of the outer cylindrical portion 31 (see FIG. 1).

  Here, in the present embodiment, the inner cylindrical portion 33 is formed to have a smaller diameter than the outer cylindrical portion 31. That is, the lower end portion 33 a of the inner cylindrical portion 33 is located above the lower end portion 31 a of the outer cylindrical portion 31. Further, as shown in FIG. 4, the central axis O1 of the outer cylindrical portion 31 and the central axis O2 of the inner cylindrical portion 33 intersect, so that the outer cylindrical portion 31 and the inner cylindrical portion 33 sandwich the flange portion 32. It extends from the portion 32 in different directions. That is, the socket 21 has a shape that bends in the middle position. Then, as shown in FIG. 2, in the state where the socket 21 is attached to the housing 19, the outer cylindrical portion 31 extends parallel to the outer surface of the housing 19.

Furthermore, in the state where the socket 21 is attached to the housing 19 on the outer surface of the outer cylindrical portion 31 and the drain pan 15 is installed at a predetermined position, the entire outer surface of the outer cylindrical portion 31 is horizontally extended. An extending horizontal line portion 35 is provided.
In the present embodiment, the predetermined position of the drain pan 15 indicates the position where the drain pan 15 is disposed on the horizontal surface.

  The horizontal line portion 35 is a groove formed on the outer surface of the outer cylindrical portion 31 or a convex portion protruding from the outer surface of the outer cylindrical portion 31. The groove and the projection can be integrally formed when the socket 21 is formed.

It has become. Then, the position where the horizontal line portion 35 is provided is determined in consideration of the liquid amount of the liquid accumulated in the outer cylindrical portion 31 and the inclination angle of the liquid surface of the accumulated liquid with respect to the horizontal plane.

Next, with reference to FIG. 5, the installation method of said air conditioner 1 is demonstrated.
First, the indoor unit 10 of the air conditioner 1 is disposed at a mounting position such as a ceiling and the like, and step S1 of temporarily fixing the indoor unit 10 is executed.
Next, step S2 of retaining liquid such as water inside the outer cylindrical portion 31 is performed. In this process, for example, after the water is stored in the drain pan 15, the drainage pump 16 is driven for a certain period of time to retain the water inside the outer cylindrical portion 31.

Further, step S3 of confirming an angular deviation between the liquid level of the liquid inside the outer cylindrical portion 31 and the horizontal line portion 35 provided in the outer cylindrical portion 31 is performed. That is, it is checked whether the liquid surface is inclined in the vertical direction with respect to the horizontal plane.
At this time, the amount of positional deviation in the vertical direction between one horizontal line portion 35 and the liquid surface of the horizontal line portions 35 provided in pairs and the amount of positional deviation in the vertical direction between the other horizontal line portion 35 and the liquid surface You may also check the difference between

  Finally, the position of the drain pan 15 and the housing 19 is adjusted so as to eliminate the above-mentioned angular deviation (and positional deviation in the vertical direction), and step S4 of installing the air conditioner 1 is executed.

  According to the air conditioner 1 of the present embodiment described above, if the drain pan 15 is not installed horizontally, the horizontal line portion 35 does not extend in the horizontal direction, and the horizontal line portion 35 is inclined in the vertical direction with respect to the horizontal direction. The socket 21 is arranged to extend in At this time, when the outer cylindrical portion 31 is viewed from the outside in a state in which the liquid is retained in the socket 21, the liquid surface of the liquid and the horizontal line portion 35 are not parallel.

  Therefore, by making the liquid level and the horizontal line portion 35 parallel (or coincident), the drain pan 15 can be installed horizontally, that is, the entire design of the drain pan 15 and the air conditioner 1 is correctly installed It becomes possible to adjust to the position. That is, with the simple configuration of the horizontal line portion 35, it is possible to easily adjust the installation positions of the drain pan 15 and the entire air conditioner 1 while suppressing the cost.

  Furthermore, since the socket 21 is for connecting the connection piping 17 of the drainage pump 16 and the drainage piping 25, the socket 21 is originally required for the air conditioner 1. Then, the drain pan 15 can be installed at the correct design position only by providing the horizontal line portion 35 in the socket 21. Therefore, it is not necessary to newly provide an additional member in order to adjust the installation position of the drain pan 15.

  Furthermore, in the socket 21 of the present embodiment, the lower end portion 33a of the inner cylindrical portion 33 is positioned above the lower end portion 31a of the outer cylindrical portion 31, and the lower end portion 33a of the inner cylindrical portion 33 and the outer side The liquid easily stagnates between the lower end portion 31a of the cylindrical portion 31 and the lower end portion 31a. That is, the liquid accumulated inside the outer cylindrical portion 31 can be blocked by the flange portion 32, and the liquid can be prevented from flowing out from the outer cylindrical portion 31 to the inner cylindrical portion 33 side. For this reason, it is possible to more reliably compare the position of the liquid surface and the position of the horizontal line portion 35 and adjust the entire drain pan 15 and the air conditioner 1 to the designed installation position.

  Furthermore, the horizontal line portions 35 are provided in pairs at the same height position, so that the amount of positional deviation in the vertical direction between one horizontal line portion 35 and the liquid surface, the other horizontal line portion 35 and the liquid surface The difference with the amount of positional deviation in the vertical direction can be confirmed together. Therefore, not only the inclination of the drain pan 15 with respect to the horizontal plane in the direction in which the horizontal line portion 35 extends, but also the inclination of the drain pan 15 with respect to the horizontal plane in the direction orthogonal to the horizontal line portion 35 can be confirmed. As a result, it is possible to more accurately install the drain pan 15 and the entire air conditioner 1 in the correct installation position.

Further, the present invention is not limited by the embodiments, and is limited only by the scope of claims.

  For example, as shown in FIG. 6, the central axis O1 of the outer cylindrical portion 31 and the central axis O2 of the inner cylindrical portion 33 intersect with each other, and the outer cylindrical portion 31 and the inner cylindrical portion 33 have the same diameter. It may be cylindrical.

  Further, as shown in FIG. 7, the lower end portion of the outer cylindrical portion 31 is disposed such that the central axis O1 of the outer cylindrical portion 31 and the central axis O2 of the inner cylindrical portion 33 are displaced in the vertical direction. The outer cylinder 31 and the inner cylinder 33 may be provided such that the lower end 33a of the inner cylinder 33 is positioned above the inner cylinder 31 than the cylinder 31a.

  Further, the socket 21 may have a shape extending straight without being bent so that the central axis O1 of the outer cylindrical portion 31 and the central axis O2 of the inner cylindrical portion 33 coincide with each other.

  The outer cylindrical portion 31 and the inner cylindrical portion 33 may not have a cylindrical shape, and may have a rectangular cylindrical shape.

  Moreover, in the above-mentioned embodiment, although the socket 21 whole is formed with a light transmissive material, only the outer side cylinder part 31 may be formed with a light transmissive material.

  Furthermore, the horizontal line part 35 may be provided only in one place.

  Also, the correct installation position of the drain pan 15 in design may be a position inclined with respect to the horizontal plane. In this case, it is necessary to provide the horizontal line portion 35 so as to extend in the horizontal direction in a state where the drain pan 15 is installed at an inclined position.
