Description

  The present invention relates to a water leakage preventing member that is attached between a through-hole provided in a plate-like body and a tubular body inserted into the through-hole, and in particular, in an outdoor unit of an engine-driven air conditioner, The present invention relates to a water leakage prevention member for preventing water leakage from an exchanger room) to a lower room (engine room).

  An outdoor unit of an engine-driven air conditioner (for example, a gas heat pump air conditioner) generally has an upper and lower two-chamber structure divided by a partition wall (drain pan). Specifically, the upper chamber (heat exchanger chamber) stores a heat exchanger that performs heat exchange between the refrigerant and air, a blower that supplies air to the heat exchanger, and the like. On the other hand, the lower chamber (engine chamber) stores a compressor that compresses the refrigerant, an engine that drives the compressor, and the like. The partition walls that partition the upper and lower chambers are provided with communication holes that communicate with the upper and lower chambers, and the refrigerant moves between the upper and lower chambers through the refrigerant transport pipe (refrigerant pipe) that passes through the communication holes (in other words, the refrigerant circuit is Circulate).

  The upper chamber (heat exchanger chamber) of the outdoor unit described above is generally provided with many openings for introducing or discharging air used for heat exchange. For this reason, rainwater or the like may enter the upper chamber through these openings. Most of rainwater and the like is guided to a dedicated drainage port provided in a partition wall (drain pan) and discharged to the outside of the upper chamber, but a part of the rainwater may flow toward the communication hole described above. Water leakage from the communication hole to the lower chamber (engine chamber) may cause deterioration of the engine, the compressor, and the like, and thus may shorten the service life of the air conditioner. Therefore, in general, a water leakage preventing member for preventing such water leakage is attached to the communication hole.

  For example, one of the conventional water leakage prevention members (hereinafter referred to as “conventional member”) has a cylindrical first part having an outer peripheral shape corresponding to the hole shape of the communication hole of the drain pan, and an outer peripheral shape of the refrigerant pipe. There are two parts, an umbrella-shaped second part having a corresponding hole-shaped opening. The conventional member is attached so that the outer peripheral surface of the first component is in close contact with the communication hole, and the refrigerant pipe is inserted into the opening of the second component to be in close contact. Thus, the conventional member is configured to block rainwater or the like traveling to the communication hole through the drain pan by the first component and blocking rainwater or the like traveling to the communication hole through the refrigerant pipe by the second component. Furthermore, since the conventional member includes two independent parts, even if the position of the refrigerant pipe with respect to the communication hole is different from the designed position (for example, misalignment due to manufacturing variation and temperature change of the refrigerant) Misalignment due to deformation of the refrigerant pipe caused by the above), rainwater or the like toward the communication hole can be blocked (see, for example, Patent Document 1).

JP 2005-274079 A

(Problems to be solved by the invention)
Since the first member and the second component can move independently of each other, the conventional member can cope with the displacement (relative displacement) of the refrigerant pipe and the communication hole. However, on the other hand, if a gap is generated between the first part and the second part due to the above-mentioned positional deviation, there is a possibility that water leaks from the gap. Although this water leakage can be prevented by applying a sealing process such as silicon coking around the conventional member, this process increases the manufacturing cost of the outdoor unit. Therefore, it is desirable to prevent leakage of water from the communication hole and cope with positional displacement of the refrigerant pipe and the communication hole without requiring a separate sealing process.

  In view of the above problems, an object of the present invention is to cope with a positional shift (relative displacement) between a through-hole provided in a plate-like body and a tubular body inserted into the through-hole, and water between them. An object of the present invention is to provide a water leakage preventing member capable of preventing leakage.

(Means for solving the problem)
The water leakage preventing member of the present invention for achieving the above-described problem is
A water leakage preventing member attached between a through hole provided in a plate-like body and a tubular body inserted into the through hole,
An outer peripheral cylindrical portion corresponding to the hole shape of the through hole, and a pair of annular protrusions protruding from the outer peripheral surface of the cylindrical portion, and both ends of the pair of annular protrusions are the cylindrical portion An annular protrusion that is separated by a distance corresponding to the thickness of the plate-like body in the axial direction of
"Second seal part" having a hole-shaped opening corresponding to the outer peripheral shape of the tubular body;
A connecting portion that connects the first seal portion and the second seal portion without a gap, and a thickness at a cut surface by a plane to which the axis belongs is smaller than both the first seal portion and the second seal portion. The thin shape and the shape at the cut surface do not include a bent portion, and the rigidity against shearing force in the direction orthogonal to the axial direction is smaller than both the first seal portion and the second seal portion. A “connecting portion”.

Furthermore, in the water leakage preventing member of the present invention,
The first seal portion, the second seal portion, and the connecting portion are formed “integrally” by an elastic body. And the water leak prevention member of this invention is comprised so that the said connection part may deform | transform by the relative displacement of the said through-hole and the said tubular body.
Furthermore, in the water leakage preventing member of the present invention ,
The second seal portion includes a tubular tubular body support portion that defines the opening, an annular convex portion that projects from an inner peripheral surface of the tubular body support portion, and an upper end of the tubular body support portion. Having a disk part that is connected and thicker than the thickness of the connecting part,
The first seal portion is located below the second seal portion,
The connecting portion is connected to the outer periphery of the disk portion and is formed in a cylindrical shape along a direction parallel to the axial direction.

  According to the above configuration, since the first seal portion has the “peripheral shape cylindrical portion corresponding to the hole shape of the through hole”, the plate-like body so that the outer peripheral surface of the cylindrical portion is in close contact with the through hole. Can be attached to. At this time, since both ends of the “pair of annular protrusions” of the cylindrical portion are separated by a distance corresponding to the thickness of the plate-like body in the axial direction of the cylindrical portion, the annular protrusion is The first seal portion can be fixed to the plate-like body by sandwiching the plate-like body in the thickness direction. On the other hand, since the second seal portion has “a hole-shaped opening corresponding to the outer peripheral shape of the tubular body”, it can be attached to the tubular body so that the inner peripheral surface of the opening is in close contact with the tubular body. Further, since the connecting portion “connects the first seal portion and the second seal portion without a gap”, there is no opening through which water can pass between the first seal portion and the second seal portion.

  Therefore, the “first seal portion” blocks water that travels through the plate-like body toward the through-hole, the “second seal portion” blocks liquid that travels through the tubular body and travels toward the through-hole, and the “connecting portion” The water which goes between the 1st seal part and the 2nd seal part and goes to a penetration hole can be intercepted.

  Further, according to the above configuration, since the “stiffness against shearing force in the direction orthogonal to the axial direction” of the connecting portion is “smaller than both the first seal portion and the second seal portion”, the tubular body and When the displacement of the through hole (generally, it can be regarded as a relative displacement in a direction orthogonal to the axial direction), the connecting portion can be deformed before the first seal portion and the second seal portion. In other words, deformation of the first seal portion and the second seal portion is suppressed, and the water blocking effect by the first seal portion and the second seal portion is maintained. In addition, since “the first seal portion, the second seal portion, and the connecting portion are integrally formed by an elastic body”, even when such deformation occurs, the gap as in the conventional member Does not occur.

  Therefore, even if displacement (relative displacement) of the tubular body and the through-hole occurs, it does not affect the functions (water blocking) of the first seal portion and the second seal portion as much as possible, and the deformation is caused by the deformation of the connecting portion. It is possible to cope with misalignment. As a result, the water leakage preventing member of the present invention can prevent water leakage from the through hole and can cope with the displacement of the tubular body and the through hole without requiring a separate sealing member unlike the conventional member.

  Therefore, the water leakage preventing member of the present invention is adapted to a position shift (relative displacement) between the through hole provided in the plate-like body and the tubular body inserted into the through hole, and the water leakage between them. Can be prevented.

  Furthermore, the water leakage preventing member of the present invention has a smaller number of parts than the conventional member (the conventional member is a composite of two members, but the water leakage preventing member of the present invention is a single continuous body), and No additional sealing member is required at the time of attachment. As a result, the water leakage prevention member of the present invention can reduce the manufacturing cost of the member itself as compared to the conventional member, and can also reduce the cost during actual use (for example, when applied to an outdoor unit of an air conditioner). It also has the effect.

  By the way, “corresponding” in the above-mentioned “cylindrical portion of the outer peripheral shape corresponding to the hole shape of the through hole” means that the hole side surface of the through hole and the outer peripheral surface of the cylindrical portion are sufficient in terms of preventing water leakage. It represents a shape that can be in close contact, and does not necessarily represent that they are the same or similar. For example, as an outer peripheral shape “corresponding” to the hole shape of the through hole, a shape similar to the hole shape of the through hole and slightly larger than the hole shape (for example, when the hole shape is a circle, than the circle) A circle having a large diameter) and a shape including a hole shape that is not similar to the hole shape of the through hole (for example, a polygon circumscribing the circle when the hole shape is a circle) may be used.

  Further, in the above-mentioned “annular protrusions whose both ends are separated by a distance corresponding to the thickness of the plate-like body in the axial direction of the tubular part” and “a hole-shaped opening corresponding to the outer peripheral shape of the tubular body” The same applies to “corresponding”. For example, both ends of the annular protrusion may be separated by the same distance as the thickness of the plate in the axial direction of the cylindrical portion (substantially the same as the thickness direction of the plate). It may be separated by a distance slightly shorter than the thickness. The opening of the second seal portion has a shape similar to the outer peripheral shape of the tubular body and slightly smaller than the outer peripheral shape (for example, when the outer peripheral shape is a circle, a circle having a smaller diameter than the circle). Although not similar to the outer peripheral shape of the tubular body, a shape included in the outer peripheral shape (for example, a polygon inscribed in the circle when the outer peripheral shape is a circle) or the like can be used.

  The above “connect without gap” means that the first seal portion and the second seal portion are connected so that there is no opening causing water leakage, and the specific shape of the connection portion is particularly Not limited. In addition, the term “integrated” means that the first seal part, the second seal part, and the connecting part are a single continuous body and are not a separable composite like a conventional member. However, the entirety of the water leakage preventing member does not necessarily need to be formed of the same material, and some of the first seal portion, the second seal portion, and the connecting portion may be formed of a material different from the other portions.

  The above-mentioned “rigidity against a shearing force in a direction perpendicular to the axial direction” is a shearing force (shearing force / deformation amount) required for causing unit deformation in each of the first seal part, the second seal part, and the connecting part. And can also be expressed as shear stiffness. For example, the “stiffness” of the first seal portion is determined when the lower end in the axial direction of the first seal portion is a fixed end and the upper end is a free end, and a force in a “direction perpendicular to the axial direction” is applied to the upper end. , And can be obtained (measured) as the magnitude of the force required to displace the upper end by a unit amount. The rigidity of the second seal part and the connecting part can be obtained (measured) in the same manner.

  Note that the water leakage preventing member of the present invention does not necessarily have to be formed of a single material. For example, in addition to this example, the connecting portion having the above-described rigidity can be formed by forming the connecting portion with a material having a smaller elastic coefficient than the material constituting the first seal portion and the second seal portion.

In addition , the second seal portion is
A cylindrical tubular body supporting portion defining the opening, is configured to have a convex portion of the annular projecting from the inner peripheral surface of the tubular body supporting portion.

  With the above configuration, the second seal portion inserts the tubular body into the opening (the hollow portion of the tubular body) defined by the “tubular tubular body support portion” and “the annular projection protruding from the inner peripheral surface”. It can be attached to the tubular body so that the "part" is in close contact with the tubular body. Note that the protrusion height and number of the “annular protrusions” are not particularly limited, and the adhesion to the tubular body required for the second seal part (in other words, water blocking property), the manufacturing cost, etc. It may be determined in consideration.

  By the way, the water leakage preventing member of the present invention can be used for various plate-like bodies and tubular bodies, and the specific application object is not particularly limited. For example, it can be suitably used for an outdoor unit of an engine-driven air conditioner because it is in an environment exposed to wind and rain and contains a device to be isolated from rainwater or the like.

Specifically, the water leakage preventing member of the present invention is
The plate-like body is a drain pan that partitions the heat exchanger room and the engine room in the outdoor unit of the engine-driven air conditioner,
The through hole is a communication hole formed in the drain pan;
The tubular body is a refrigerant transport pipe inserted into the communication hole.
Can be used.

  With the above configuration, it is possible to prevent water leakage from the communication hole of the drain pan to the engine room, and it is possible to prevent deterioration of equipment (such as an engine and a compressor) in the engine room.

<Outline of members>
Hereinafter, a schematic configuration of a water leakage prevention member 100 (hereinafter referred to as “execution member 100”) according to an embodiment of the present invention will be described with reference to the drawings.

  The implementation member 100 is attached to an outdoor unit 200 of an engine-driven air conditioner (hereinafter referred to as “GHP”). FIG. 1 shows a schematic configuration of an outdoor unit 200 to which the implementation member 100 is attached. Hereinafter, for convenience, the configuration of the outdoor unit 200 will be described before the configuration of the implementation member 100 is described.

  The outdoor unit 200 has a heat exchanger chamber (upper chamber) 200a and an engine chamber (lower chamber) 200b separated by a drain pan 201. The heat exchanger chamber 200 a is a space surrounded by the upper surface of the drain pan 201 and the housing 202, and the engine chamber 200 b is a space surrounded by the lower surface of the drain pan 201 and the housing 202.

  The heat exchanger chamber 200a stores a heat exchanger 203 that performs heat exchange between the refrigerant and air, and blowers 204a and 204b for supplying air to the heat exchanger 203. On the other hand, the engine room 200b is discharged from a gas engine 205 that uses city gas and propane gas as fuel, a compressor 206 that compresses refrigerant using the driving force output from the gas engine 205, and the compressor 206. A four-way switching valve 207 that guides the refrigerant in a direction according to the GHP operation mode (cooling operation or heating operation), an accumulator 208 that performs gas-liquid separation of the refrigerant before compression sucked into the compressor 206, and a gas engine A sub heat exchanger 209 that performs heat exchange between the exhaust heat 205 and the refrigerant is stored. The flow rate of the refrigerant flowing through the sub heat exchanger 209 is adjusted by the flow rate adjustment valve 210.

  Each member mentioned above is connected by the refrigerant | coolant pipe 211 through which a refrigerant | coolant passes, and comprises the refrigerant circuit. The refrigerant circuit extends in the right direction in the figure and is connected to a GHP indoor unit (not shown). Thereby, the refrigerant | coolant compressed by the compressor 206 circulates through a refrigerant circuit. The cooling water pipe 212 that connects the gas engine 205 and the sub heat exchanger 209 is a pipe that transports the cooling water of the gas engine 205 and does not belong to the refrigerant circuit.

  The drain pan 201 is provided with a communication hole that connects the heat exchanger chamber 200a and the engine chamber 200b, and a refrigerant pipe 211 passes through the communication hole (details will be described later). The execution member 100 is attached between the communication hole and the refrigerant pipe 211 so as to prevent water leakage between the communication hole and the refrigerant pipe 211. In this example, the communication holes (and the implementation member 100) are provided at two locations, but the number of communication holes (and the implementation member 100) is determined according to the structure of the outdoor unit and is not necessarily limited to two locations. Not.

  FIG. 2 is a cross-sectional view illustrating a state in which the implementation member 100 is attached to the drain pan 201 (portion A in FIG. 1). As shown in this figure, the drain pan 201 has an opening 201a at a position where the implementation member 100 is attached, and is substantially perpendicular to the upward direction (the direction toward the heat exchanger chamber 200a) around the opening 201a. It is curved. An inner peripheral surface 201b of the curved drain pan 201 defines a communication hole that communicates the heat exchanger chamber 200a and the engine chamber 200b. Therefore, hereinafter, the inner peripheral surface 201b is referred to as “communication hole 201b”.

  The implementation member 100 has a cylindrical shape as a whole, as shown in the figure. More specifically, the implementation member 100 includes a first seal portion 101, a second seal portion 102, and a connecting portion 103. The first seal portion 101, the second seal portion 102, and the connecting portion 103 are integrally formed of an elastic body (in this example, ethylene / propylene / diene rubber, EPDM). In other words, the implementation member 100 is a single continuous body including the first seal portion 101, the second seal portion 102, and the connecting portion 103.

  The first seal portion 101 includes a cylindrical portion 101a having an outer peripheral shape (outer peripheral surface 101a1) corresponding to the hole shape of the communication hole 201b, and a pair of annular protruding portions 101b and 101c protruding from the outer peripheral surface 101a1 of the cylindrical portion 101a. Have. More specifically, in plan view, the communication hole 201b is circular, and the shape (shape in plan view) of the outer peripheral surface 101a1 of the tubular portion 101a before attachment is a circle having a slightly larger diameter than the communication hole 201b. is there. Thereby, the outer peripheral surface 101a1 of the cylindrical part 101a after attachment closely_contact | adheres to the hole side surface of the communicating hole 201b, and the rainwater etc. which go to the communicating hole 201b through the drain pan 201 are interrupted | blocked.

  Furthermore, the tips of the annular projecting portions 101b and 101c are separated by a distance corresponding to the thickness of the drain pan 201 in the axial direction AX of the tubular portion 101a. More specifically, in this cross-sectional view, both tip portions before attachment are separated by a distance slightly shorter than the thickness of the drain pan 201. As a result, the annular protrusions 101b and 101c after the attachment sandwich the drain pan 201 from above and below, and the rainwater and the like that travels along the drain pan 201 toward the communication hole 201b is blocked. As a result, the execution member 100 is fixed to the drain pan 201.

  The annular projecting portion 101b and the drain pan 201 define a gap B having a substantially triangular cross section. Therefore, even when rainwater or the like traveling through the drain pan 201 due to aging or the like passes between the annular protrusion 101b and the drain pan 201, the rainwater or the like is temporarily stored in the gap B. As a result, rainwater or the like traveling through the drain pan 201 toward the communication hole 201b is more reliably blocked.

  The second seal portion 102 includes a cylindrical pipe support portion 102a having a hole shape corresponding to the outer peripheral shape of the refrigerant pipe 211, and a disk portion 102b to which the pipe support portion 102a is connected. Furthermore, the 2nd seal | sticker part 102 has two cyclic | annular convex parts 102a1 and 102a2 which protrude from the internal peripheral surface of the pipe support part 102a. The inner peripheral surface of the pipe support portion 102a and the annular convex portions 102a1 and 102a2 define an opening for inserting the refrigerant pipe 211. More specifically, in plan view, the outer peripheral surface of the refrigerant pipe 211 is circular, and the inner peripheral surface of the pipe support portion 102a before attachment (particularly, the tips of the annular convex portions 102a1 and 102a2) is from the refrigerant pipe 211. Is a circle with a slightly smaller diameter. As a result, the inner peripheral surface (particularly, the annular convex portions 102a1 and 102a2) of the pipe support portion 102a after being attached is in close contact with the outer peripheral surface of the refrigerant pipe 211, and rainwater or the like that travels through the refrigerant pipe 211 toward the communication hole 201b. Will be blocked.

  The connecting portion 103 has a thin shape in which the thickness of the cut surface (that is, the cut surface shown in FIG. 2) by the plane to which the axis AX belongs is smaller than both the thicknesses of the first seal portion 101 and the second seal portion 102. Have. As a result, the connection portion 103 is less rigid than the first seal portion 101 and the second seal portion 102 in terms of shearing force in the direction orthogonal to the axis AX (for example, the left-right direction in the drawing of FIG. 3). ing.

  In this example, the thickness of the first seal portion 101 is the thickness of the disk portion 102b connected to the upper end portion of the connecting portion 103, and the thickness of the second seal portion 102 is the lower end portion of the connecting portion 103. The thickness of the connected cylindrical part 101a was used. Further, when measuring the rigidity of the connecting portion 103, for example, “the lower end (connection position with the first seal portion 101) in the axial direction AX of the connecting portion 103 is a fixed end and the upper end (connection with the second seal portion 102). When the position) is a free end and a force in a direction perpendicular to the axial direction AX is applied to the upper end, the magnitude of the force required to displace the upper end by a predetermined unit amount can be used as the rigidity. Similarly, regarding the rigidity of the first seal portion 101 and the second seal portion 102, “shearing force for causing unit deformation in the case where the lower end in the drawing is a fixed end and the upper end and the free end are used” is defined as the rigidity. Can be used.

  The above is the outline of the implementation member 100.

<Response to misalignment>
With reference to FIG. 3, a state in which the execution member 100 corresponds to a positional shift (relative displacement) between the communication hole 201 b and the refrigerant pipe 211 will be described.

  For example, as shown in the figure, when the refrigerant pipe 211 is relatively displaced in the right direction with respect to the communication hole 201b (see the solid line arrow in the figure), the rigidity of the connecting portion 103 is the first seal portion 101 and Since it is smaller than both of the second seal portions 102, the connecting portion 103 is deformed before the first seal portion 101 and the second seal portion 102 (see broken line arrows in the figure). Furthermore, since the first seal portion 101, the second seal portion 102, and the connecting portion 103 are integrally formed of an elastic body, a gap may be generated between the members even when such deformation occurs. Absent.

  As a result, this relative displacement can be accommodated without substantially affecting the functions of the first seal portion 101 and the second seal portion 102 (blocking rainwater or the like). The same applies to the case where the refrigerant pipe 211 is relatively displaced in the left direction with respect to the communication hole 201b.

  As described above, the execution member 100 can prevent water leakage between the communication hole 201b provided in the drain pan 201 and the refrigerant pipe 211 inserted in the communication hole 201b while corresponding to the relative displacement. Can be prevented.

<Other aspects>
The present invention is not limited to the above embodiment, and various modifications can be employed within the scope of the present invention.

For example, leakage prevention member of the present invention, as shown in FIG. 4, as connecting portion 103 is formed by a material elastic modulus smaller than that of the material constituting the first seal portion 101 and the second seal portion 102 May be configured. With this configuration, the connecting portion 103 has a thickness comparable to that of the first seal portion 101 and the second seal portion 102, but has a rigidity (axis line) smaller than both the first seal portion 101 and the second seal portion 102. And rigidity against shearing force in a direction perpendicular to AX).

Further, the second seal portion 102 of the implementation member 100 is formed so that the pipe support portion 102a is located inside the implementation member 100 (positioned below the disk portion 102b). However, as shown in FIG. 5 , the water leakage preventing member of the present invention may be formed so that the pipe support portion 102a is located outside the implementation member 100 (so as to be located above the disk portion 102b). .

  Furthermore, the implementation member 100 is attached to the drain pan 201 of the outdoor unit 200 of the engine-driven air conditioner. However, the water leakage preventing member of the present invention may be attached to another device or the like as long as it is between a plate-like body having a through hole and a tubular body inserted into the through hole.
