The present invention relates to an outdoor unit, such as an air conditioner, in which a carrying handle is formed on a part of a box by integral molding.

In a conventional outdoor unit such as an air conditioner, a carrying handle is integrally formed on a part of a box upper surface plate (see, for example, Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4).

Patent Literature 1, when installing a handle for carrying other components on the side plate of the outdoor unit, protrudes into the inside of the box so that the depth of the handle can be largely secured to avoid contact with the parts arranged inside the box. In order to eliminate the problem which is hard to hold by hand, it is the document which integrally formed so that one part of the resin box upper surface board (with a reinforcing metal cover) may protrude left and right.

Patent Literature 2 extends a part of the plane of the upper plate laterally to protrude from the side plate, and forms a flange portion that is bent downward and a downward opening surrounded by the side plate as a handle. In addition, a box structure is described in which a flange portion is fitted to a stepped portion provided in addition to the handle corresponding portion of the upper end of the side plate, and the handle corresponding portion is mounted on a horizontal flange at the top of the side plate to support the top plate without providing a step portion. have. As a result, the document secures a distance between the heat exchanger and the side plate and prevents the occurrence of abnormal sounds due to contact between the heat exchanger and the side plate.

Patent document 3 comprises an outdoor unit comprising a side plate and an upper plate of an outer box, and the side plate has a step portion recessed into the box body at the upper end portion, and the upper plate has a downward peripheral flange portion fitted to the step portion of the side plate. And a handle protruding outward from the side plate, and the flange tip portion of the base of the protruding portion is folded toward the inner ceiling surface. By doing in this way, it is a document which provides the outdoor unit which is safe, excellent in strength, and excellent in strength, and has little warpage and deformation, further excellent in design, and which can be manufactured from a thin material.

Patent document 4 is a pipe insertion through part through which a pipe connected to a refrigeration cycle device such as a compressor or a heat exchanger penetrates into a part of the back side of the ceiling plate which blocks the upper opening of the housing, and the outdoor unit is transported to both left and right sides of the ceiling plate. The handle part used at the time is integrally formed so that it may protrude inside the box body. Its feature is that the center of gravity of the outdoor unit body is located at the midpoint connecting the pair of handles for transportation. As a result, since the handle, which is a conventional separate part, is provided, it is easy to fall off and is designed to fit the handle using an empty space, so that the relationship with the center of gravity of the entire outdoor unit is not considered, and the weight balance is bad. This document solves the problem of poor transportability.

An embodiment of the present invention will be described with reference to Figs.

FIG. 6 is an overall perspective view of the outdoor unit of the first embodiment of the outdoor unit opened from the right inclined upper side, FIG. 7 is an overall perspective view of the outdoor unit of the first embodiment of the outdoor unit opened from the left inclined upper side, FIG. 9 is a front view of the outdoor unit according to the first embodiment, FIG. 9 is a right side view of the outdoor unit according to the first embodiment, FIG. 10 is a perspective view of the upper surface member of the outdoor unit according to the first embodiment as seen from above the right inclination, and FIG. If a partial perspective view showing the parts of the handle member from the back surface.

As shown in Figs. 6 to 9, the outdoor unit of the present embodiment constitutes the box main body 1 with the bottom surface portion and the four side surfaces, and closes the opening of the upper surface of the box main body 1 with the upper surface member 2. As a result, the entire body is constructed. The blower 6, the heat exchanger 7, the compressor 8, and the like are built in the box body. The blower cover 5 is provided in the front surface of the blower 6. The outdoor unit uses a handle used for transporting to form a finger insertion space 3 at a position opposite the handle portions 2a and 2d of the upper surface member 2 and the handle portions 2a and 2d. It consists of the recessed parts 1b and 1g formed so that it may become recessed inside itself.

The handle portion 2a and the handle portion 2d are integrally formed at the short side end portion of the upper surface member 2. The handle portion 2a and the handle portion 2d are for holding hands. As shown in Figs. 4, 10 and 11, the plate of the end portion 2b of the upper surface member 2 is bent inward. It is formed, and is formed on the same side as the side surface of the handle part 2a and the edge part 2b of the handle part 2d, and the side surface of the adjacent edge part 2b.

When the upper surface member 2 is coupled to the box main body 1, the screw hole 1c and the screw hole 2c are superimposed and both holes communicate. A screw (screw 4 shown in Fig. 5) is screwed into this nested hole to fix it integrally. The structure of the handle in this fixed state is as shown in Figs. 1 and 2, which are partial cross-sectional views, and Fig. 5, which is a partial side view. That is, the said handle part 2a and the handle part 2d are formed in the short side edge part of the upper surface member 2. As shown in FIG. And the recessed part 1b and the recessed part 1g are formed in the position corresponding to the handle part 2a and the handle part 2d in the short side upper end part of the side surface of the box main body 1. As shown in FIG. This recessed part 1b and the recessed part 1g are formed so that it may be recessed in a box inside in the plastic molding process by a press machine etc.

The heavy compressor 8 is provided at the right end of the box body 1 as shown in Figs. The recessed portion 1b is provided on the side where the large compressor 8 is installed. Moreover, the recessed part 1g is provided in the opposite side part part in which the compressor 8 was installed. Therefore, as shown in Fig. 3, the concave portion 1b is subjected to plastic molding of the width dimension W1 of the depth portion of the concave portion and the width dimension W2 of the opening portion of the concave portion, thereby increasing the lateral strength of the box body. In the Example, the width dimension W1 of the depth part of the recessed part 1b set 65 mm and the width dimension W2 of the opening part to 85 mm. Thereby, four fingertips other than a thumb can be inserted to the inside without difficulty.

Since the width dimensions W1 and W2 are made large, not only the side strength of the box is increased, but also the finger is inserted into the finger insertion space 3 to the inside enough so as to show the handle portion 2a as shown in FIG. ) Can be firmly supported.

On the other hand, since the weight on the opposite side where the compressor 8 is installed is light, even if the hand is held on the handle 2d and the outdoor unit is lifted up, no large load is applied to the hand. For this reason, since the recessed part 1g formed in the position which opposes the handle part 2d does not need to insert a lot of fingers compared with the recessed part 1b, the recessed part 1g recesses the magnitude | size of the plastic molding of the recessed part 1g. It made smaller than the part 1b. Since the opposite side recessed part 1g provided with the said compressor 8 can be made smaller than the recessed part 1b, as shown in FIG. 7, so that it may become recessed in the space side formed by the bending part of the heat exchanger 7. As shown in FIG. It is designed not to enlarge the outdoor unit.

Moreover, the reinforcement part 1a by press machine shaping | molding is formed in the side surface of the compressor 8 side of the outdoor unit as shown in FIG. 1, FIG. 2, FIG. 6, and FIG. This suppresses the occurrence of warpage when the external force or the outdoor unit is stacked and its weight is applied to the outdoor unit.

The upper end part 1d of the side surface of the box main body 1 bends the upper end surface in a curved surface. As a result, the lateral strength of the box is increased, making it difficult to distort the box side. Moreover, even when it is bent at a right angle, the effect of securing the same strength can be obtained. The upper end surface 1e of the said recessed part 1b is concave inside a box so that it may continue integrally with the upper end surface of the flat part of the said side part.

In addition, although the box main body 1 is made to bend the side part at right angles, when it is bent at right angles, since the upper end part 1d is curved at the curved surface, this curved surface will be greatly reduced and a big wrinkle will be produced. Furthermore, there exists a possibility that the whole box main body may deform | transform. In order to prevent this, as shown in Fig. 3, the curved portion 1d of the upper end of the portion bent at a right angle is cut to form the cutout portion 1f.

By setting the outdoor unit to the configuration of the following embodiment, the effect of the embodiment corresponding to the first problem can be obtained.

For example, the upper surface member 2 has a carrying handle portion 2a integrally formed at the short side end portion 2b, and a side portion of the box body 1 is integrated at a position corresponding to the handle portion 2a. A concave portion 1b formed in the box body and concave inside the box, and a flat portion adjacent to the concave portion 1b, and the concave portion 1b has an upper end surface 1e of the concave portion 1b. It is recessed inwardly in the box body so that it may be integrally continuous with the upper end surface of the flat part adjacent to the upper surface, The said upper surface member 2 is mounted in the upper end surface 1e of this recessed part 1b, and this recessed part 1b ), And a finger insertion space 3 is formed between the handle portion 2a of the upper surface member 2 to constitute the handle.

Although not shown, in the case where the upper member 2 is mounted on the upper end face 1e of the recess 1b, the gap is made small by intervening inclusions therebetween, so that the rain can be kept inside even against severe weather. Even if it is prevented from invading and even if the installation worker burns on the upper surface member 2, since it is not directly pressed by the upper end surface 1e of the said recessed part 1b, the trace deformed in the shape of the upper end surface 1e is It can be prevented from remaining unsightly in the upper surface member 2.

The upper end 1d of the side surface of the box main body 1 is curved at its upper end surface, whereby the strength is improved, making it less likely to cause distortion and deformation with respect to the force in the horizontal direction, The shape of the fitting portion can be formed into a predetermined shape. Even when the curved surface is bent at a right angle instead of the curved surface, the same effect as securing the strength can be obtained as when the curved surface is bent.

Moreover, the recessed part 1b plastic-molded by the press machine etc. integrally in the side part of the box main body 1 is recessed inwardly in the box body so that the upper end surface 1e may continue integrally with the upper end surface of the flat part of the said side part. It is supposed to be done. By doing in this way, the side part in which this recessed part 1b was provided can increase the intensity | strength with respect to the load of a perpendicular direction. By providing this recessed part 1b, even if plural outdoor units are laminated, deformation can be suppressed. In this case, even if only the compressor 8 side with a large weight is obtained, an effect is acquired.

Moreover, the upper end surface of the flat part of the side part and the upper end surface of the recessed part 1b were formed so that it may be integrally continuous. As a result, the box strength is increased, and therefore, it is possible to ride on the upper surface member 2 of the outdoor unit during the operation of the refrigerant pipe and the electric wiring, and to perform the installation work of the refrigerant pipe and the electrical wiring. Moreover, since the upper end surface of the recessed part 1b was formed so that it may be integrally continuous with the upper end surface of the flat part of a side part, a clearance gap will disappear or a clearance gap will become small. As a result, the rainstorm does not penetrate inside, and it is possible to prevent the electrical appliances from being damaged.

The upper end face 1e of each of the recessed part 1b and the flat part adjacent to the recessed part 1b, and the part where these upper end faces 1e are integrally continuous, are bent in the horizontal direction from the vertical part. Doing

Thus, the upper end surface 1e of each of the recessed part 1b and the flat part adjacent to this recessed part 1b, and the part in which these upper end surfaces 1e are integrally continuous bend | folded horizontally from a vertical part. By having such a shape, the strength increases with respect to the load applied to the outdoor unit, in particular with respect to the load in the horizontal direction and the load in the inclined direction, thereby suppressing deformation of the box body. In addition, since the upper end surface 1e has a shape bent in the horizontal direction, when the outdoor unit is folded or a person rides on the outdoor unit to perform plumbing work of the air conditioner, the upper member 2 is the upper end surface of the box body. Even if it is strongly pressed by (1e), since it is in surface contact with the upper surface member 2, it becomes difficult to leave the trace of the strain deformation on the upper surface member 2.

Further, the upper surface member 2 is mounted on the upper end surface 1e of the recess 1b by contacting the lower surface of the upper surface member 2 or via the inclusions, thereby increasing the unity of both members and between the two members. It is possible to prevent the rainstorm from invading the interior and damaging the electrical appliance by making the gap of the gap small. In addition, by interposing an intervening portion between the upper end surface 1e of the recess 1b and the lower surface of the upper member 2, when an outdoor unit is stacked or a person rides on the outdoor unit, such as piping work of an air conditioner. Even if the upper surface member 2 is strongly pressed on the upper end of the box body, it is not directly pressed, so that it is difficult to leave a trace of deformation.

Next, according to the structure of the following Example, the effect of the Example corresponding to a 2nd subject can be acquired.

The thickness dimension D2 of the part bent inside the handle part 2a and the handle part 2d was 3 mm. In particular, since the handle part 2a is a side in which the compressor 8 with a large weight is provided, it is good to enlarge the bending thickness dimension D2. However, when this bending thickness dimension D2 is enlarged, the dimension D1 of the recessed part 1b which forms the said finger insertion space 3 must also be enlarged. Therefore, the bending thickness dimension D2 was made into 3 mm as the minimum required size which can reliably receive the load to a finger at the time of conveyance. Since the dimension D1 of the said recessed part 1b is 16 mm in an Example, the insertion width dimension of a substantially finger is D1-D2 = 13 mm.

The bent portions of the handle portion 2a and the handle portion 2d do not necessarily need to be formed on the same plane as the other portions of the upper surface member 2 adjacent to each other. If the bending thickness dimension D2 is a small dimension of about 3 mm in advance, for example, it is small and partial even if protruding from the side surface of the box, so that it is almost not a problem in the external dimension. That is, since it is almost absorbed by the thickness of a packaging material, it is not necessary to enlarge the magnitude | size of the external dimension of the whole packaging material, and also there can be almost no adverse effect that the number of loading to a conveyance vehicle becomes small. Thus, the portion bent toward the finger insertion space 3 side of the handle portion 2a shown in Figs. 1 and 2 is molded so as to partially protrude out of the box by about 3 mm of the bending thickness dimension D2. You may also In this way, since the dimension D1 of the recessed part 1b does not need to be 16 mm, but can be set to 13 mm, the size of a box body can be made small 3 mm from one side, and both sides, namely, a box body It can also be made 6 mm small in the whole. However, when projecting the bent part to the outside of a box body, it is preferable to make the vertical height dimension H2 of the handle part 2a 20 mm or more. That is, when the vertical height dimension H2 of the handle part 2a is less than 20 mm, when the outdoor unit is lifted up, the finger does not become in the vertical direction (including the inclination of 45 degrees or more) by the load applied to the finger. Establishment is high. Therefore, when the vertical height dimension H2 of the handle part 2a is less than 20 mm, the part bent to the finger insertion space 3 side will be made to protrude to the finger insertion space 3 side, and it will be easy to catch on a finger. It is preferable to make transportation easy by making it hard to slip. In addition, the vertical dimension H1 of the edge part of the upper surface member 2 of an Example is 17 mm, the vertical height dimension H2 of the handle part 2a is 16 mm, and it is almost the same dimension except a plate thickness dimension. . The vertical height dimension H3 of the recess 1b is 65 mm. By the reinforcing effect of the side plate by the recessed part 1b of this Example, when it was set as the box strength about the same as the conventional plate thickness dimension of 0.8 mm, it was set as the plate thickness dimension of 0.6 mm.

Moreover, the said recessed part 1b is provided in the side in which the compressor 8 with a big weight is provided. Therefore, as shown in Fig. 3, the concave portion 1b is subjected to plastic molding of the width dimension W1 of the depth portion of the concave portion and the width dimension W2 of the opening portion of the concave portion, thereby increasing the lateral strength of the box body. In the Example, the width dimension W1 of the depth part of the recessed part 1b set 65 mm and the width dimension W2 of the opening part to 85 mm. Thereby, four fingertips other than a thumb can be inserted to the inside without difficulty.

Since the width dimensions W1 and W2 are made large, not only the side strength of the box is increased, but also the finger is inserted into the finger insertion space 3 to the inside enough so as to show the handle portion 2a as shown in FIG. ) Can be firmly supported. Therefore, even when the weight of the compressor 8 is large, the handle portion 2a can be reliably held by the finger and lifted up, so that the finger can withstand the load sufficiently and can be easily carried.

That is, a force pushing downward in the vertical direction by a large load acts on the joint of the palm-side finger than the part supporting the lower end of the handle portion 2a. However, since the tip of the finger is bent upward in the vertical direction, the bent joint as shown in FIG. 1 is easy to counter the force (load) pushed downward in the vertical direction, and the bent joint does not increase the bending angle. It becomes easy.

The compressor 8 is provided on one end side in the left-right direction of the box body 1. The center position in the depth direction of the concave portion 1b is provided at a position far from the center position in the depth direction of the outdoor unit or the center position in the depth direction of the compressor 8 from the blower cover 5 side.

The lower end of the recess 1b and the lower end of the handle 2a are preferably 15 mm or more and less than half of the height dimension of the box body 1. This is a range in which the effect of preventing deformation of the box body is obtained, and when it becomes more than half of the height dimension of the box body 1, when the outdoor unit is lifted in an inclined state, it is caused by the load of the heavy compressor 8. This is because the effect of suppressing deformation of the box is almost eliminated. That is, although the intensity | strength with respect to the load of the inclination direction, or the strength with respect to the load of the torsion direction is made high in the lower end part of the recessed part 1b, and the recessed upper end surface 1e, more than half of the height dimension of the box main body 1 In this case, the effect of the strength improvement on the load in the oblique or torsional direction becomes small.

The upper surface member 2 has a carrying handle portion 2a integrally formed at the short side end portion 2b, and the side surface portion of the box body 1 is moved into the box body at a position corresponding to the handle portion 2a. It has a recessed part 1b, and the vertical height dimension H3 of this recessed part 1b is 15 mm or more larger than the vertical direction dimension H2 of the said handle part 2a, and of the box main body 1 is carried out. It was made less than half of height dimension.

Since the vertical height dimension H3 of the recessed portion 1b is 15 mm or more larger than the vertical dimension H2 of the handle portion 2a, the surface of the recessed portion 1b and the handle portion 2a A fingertip may be formed between the inner surfaces in a vertical direction and at least a first joint may be inserted into the vertical direction. In this way, at least the first joint is inserted in the vertical direction, so that the fingertip tip supports the upper back surface side of the upper surface member 2 and the middle of the fingertip supports the lower end of the handle portion 2a. It is easier to counter the load in the direction of pushing down the joint of the finger on the palm side, that is, the larger load in the direction of increasing the bending angle of the bent joint than the support of the finger.

As a result, even a large load can be carried more comfortably than an outdoor unit supporting the handle portion 2a at an angle close to the horizontal direction, that is, less than 45 degrees with respect to the horizontal direction. It is also easy to climb stairs and carry them upstairs.

In addition, in order to be able to carry it without difficulty even if it is supported in the state close to the horizontal direction, the depth dimension which can insert a fingertip largely in a horizontal direction is needed. In the case of the standard outdoor unit with a weight of 35 kg, it was confirmed that a depth dimension that can be inserted beyond the first joint even from the tip of the fingertip was confirmed at the minimum. In the experiment example, even at least 25 mm was required, Preferably it was 30 mm or more. When attempting to make a large depth dimension in the horizontal direction in this way, it becomes impossible to form the recessed part 1b by plastic molding process so that the upper end part of the side surface of a box may be recessed inward, and another component is needed. In addition, since the dimension H2 in the vertical direction of the handle portion 2a is small, the strength of the handle portion 2a is not sufficient, and the force of the fingertip is applied to a portion away from the handle portion 2a by 30 mm or more, so that the upper surface member There is a possibility that (2) is deformed. In order to prevent this deformation, it is necessary to increase the plate thickness or to secure the strength by partially protruding the handle portion 2a outward as in the conventional literature. Therefore, the parts cost not only increases that much, but also brings about the same problems as the above-described prior art. Moreover, it is also difficult to ensure the strength which can endure the lamination | stacking of the outdoor unit which is the objective of this invention fully.

By increasing the vertical height dimension H3 of the concave portion 1b concave inwardly into the box body by 15 mm or more than the vertical dimension H2 of the handle portion 2a, the fingertips are not increased. There is no need to protrude the handle as it can form a space for insertion. Thereby, external dimension can be made small, Furthermore, packaging boxes, such as a corrugated box, can also be made small and it leads to resource saving. Moreover, since the external dimension is small, it is possible to increase the number of loadings to the transport vehicle and the number of storages of the storage warehouse.

When the center position in the depth direction of the concave portion 1b is located at a position far from the center position in the depth direction of the outdoor unit or the center position in the depth direction of the compressor 8 from the blower cover side, the weight when the operator lifts and transports Since the center is located between the hand that is in contact with the handle and the boat that is in contact with the blower cover side, it is easy to lift the load without the hand being applied only to it. Since is secured, distortion and deformation of the box due to the weight of the outdoor unit can be suppressed.

The handle has a vertical dimension H2 equal to the vertical dimension H1 of the end portion 2b of the upper surface member 2 between the face of the recess and the inner surface of the handle. It is possible to form a space in which the fingertips can be inserted in the vertical direction, and at the same time, the engagement of the fingertips on the handles is very well stabilized and can be held.

The handle has a vertical dimension that is smaller than the vertical dimension H1 of the end portion 2b of the upper surface member 2 and is a vertical dimension H4 that is 1/2 or more, so that the surface of the recess and the It is possible to form a space in which the fingertips can be inserted in the vertical direction between the inner surfaces of the handles, and at the same time, the locking of the fingertips on the handles can be sufficiently secured.

The handle is formed on a part of the short side end portion 2b of the upper surface member 2 so that a space for inserting a fingertip is formed between the surface of the recess 1b and the inner surface of the handle, and the upper surface member ( By forming it so that it might not protrude from the outer peripheral surface of the short side edge part 2b of 2), an external dimension could be made small.

The dimensions H2 and H4 in the vertical direction of the handle portion 2a integrally formed at the end 2b of the upper surface member 2 were in the range of 20 mm to 40 mm. Since the dimension H1 in the vertical direction of the handle is in the range of 20 mm to 40 mm, the fingertip can sufficiently hold the handle. For example, in the case of 200 mm, the handle can be reliably held by inserting the finger insertion space from the fingertip to the vicinity of the first joint. In addition, in the case of 40 mm, it can insert in a finger insertion space from the fingertip to the vicinity of a 2nd joint, can contact with a handle with a large area, and can hold | maintain firmly. In addition, since the contact with a large area, the weight to the finger is widely dispersed in the contact surface of the finger, the load burden is smaller than in the case of 20 mm, it can be held more securely.

The dimension H3 of the vertical direction of the recessed part 1b recessed inside the said box body was 40 mm or more to half or less of the vertical height dimension of the said box body. By setting it to 40 mm or more, the finger can be bent in an unobtrusive manner and inserted into the finger insertion space in a substantially vertical direction, so that the outdoor unit can be lifted by holding the handle without difficulty. This facilitates walking and climbing of stairs in a state where the outdoor unit is lifted up. Moreover, if it is a small outdoor unit, it can also carry by yourself.

Second Embodiment

Fig. 12 is a cross-sectional view of the outdoor unit's handle portion of the air conditioner showing the second embodiment of the present invention, and Fig. 13 is a perspective view of the upper surface member 2 'of the outdoor unit of the second embodiment as seen from the right incline.

The upper surface member 2 'of the present embodiment has a carrying handle 2a' integrally formed at the short side end 2b ', and the side surface of the box body 1 corresponds to the handle 2a'. It has the recessed part 1b recessed inwardly in a box at one position, and the vertical height dimension H3 of this recessed part 1b is 15 mm or more than the vertical dimension H4 of the said handle part 2a '. In addition, it was made into half or less of the height dimension of the box main body 1. As shown in FIG. Specifically, the vertical dimension H1 of the end portion 2b 'of the upper surface member 2' is 20 mm, the vertical height dimension H4 of the handle portion 2a 'is 11 mm, and the vertical dimension ( It was made into the dimension more than half of H1). The vertical height dimension H4 of the handle portion 2a 'was 11 mm, as shown in the figure, the distal end portion of the handle portion 2a' was bent toward the finger insertion space 3 'to engage the finger. The depth dimension of the finger insertion space 3 'is set to around 15 mm, and the vertical height dimension H3 of the recessed portion 1b is the vertical dimension H4 of the handle portion 2a'. This is because it is formed to be larger than 15 mm, thereby allowing the fingertip to be inserted in the direction perpendicular to the finger insertion space 3 '.

Although the vertical height dimension H3 of the recessed part 1b of this 2nd Example is 65 mm which is the same dimension as 1st Example, it was confirmed that even if it is 26 mm and 30 mm of a test product, it is easy to fully support. However, in the reinforcement effect of the side plate by the recessed part 1b recessed by plastic working, it cannot be said that it is sufficient compared with the case of 65 mm, and it is just the recessed part 1b of the upper surface member 2 '. When a person was burned in the above position, the periphery of the recess 1b of the side plate was slightly distorted. This is enough strength if it is only burned at the time of installation work, but when it is laminated and transported to a vehicle, it is preferable that it is 45 mm or more in order to obtain a very large reinforcement effect, assuming that a large impact is applied. It was confirmed. Thereby, between the surface of the recessed part 1b and the inner surface of the said handle part 2a ', the space where a fingertip can be inserted in a perpendicular direction at least 1st joint can be formed. In this way, at least the first joint can be inserted in the vertical direction, so that the fingertip front end supports the upper back surface side of the upper surface member 2 'while the middle of the fingertip slides the lower end of the handle portion 2a'. I can support it in a state that is hard to lose.

Thereby, even a large load can be carried without difficulty compared with the conventional outdoor unit which does not protrude of the handle which supports the handle part 2a at the angle of a fingertip close to a horizontal direction, ie, less than 45 degree | times with respect to a horizontal direction, For example, it is easy to carry upstairs in a customer's home and upstairs.

According to the present invention, the concave portion formed integrally with the side portion of the box body is concave inwardly into the box body, with the upper end surface thereof being continuously contiguous with the upper end surface of the flat portion adjacent to the concave portion. Since the side part provided with the recessed part can increase the intensity | strength with respect to a load, and comprised the handle by forming the space for finger insertion between this recessed part and the handle part of an upper surface member, a carrying handle protrudes substantially to the left and right of the box upper surface board. By combining the shape of the handle portion with the shape of the concave portion of the side of the box main body, the first problem can be provided that can provide an outdoor unit that can secure the strength of the box without increasing the external dimension of the outdoor unit. You can get the effect.

According to claim 2, the upper end face of the concave portion is concave so as to be integrally continuous with the upper end face of the flat portion adjacent to the concave portion, and the upper end face of the concave portion has a shape bent in the horizontal direction from the vertical portion of the concave portion. With respect to the load applied to the outdoor unit, in particular, the strength increases with respect to the load in the horizontal direction and the load in the inclination direction, thereby suppressing deformation of the box body.

According to claim 3, since the compressor is provided on one end side in the left and right directions of the box body, the effect can be obtained even when the compressor side having a large load is configured as the configuration of claim 1. When the recess is provided at one end side in the left and right directions of the box main body, one of the left and right sides of the side part of the box main body, the side part at the side where the blower cover adjacent to this surface is installed, the side part at the heat exchanger side, the upper surface member, and the compressor The improvement by the synergistic effect of the combined strength of the floor member to load can be anticipated.

Thus, when laminating | stacking multiple outdoor units, what is necessary is just to laminate | stack so that the compressor side of another outdoor unit may be superimposed on the compressor side.

In addition, such an outdoor unit can also be mounted on the compressor side of the outdoor unit by the operator to perform installation work such as refrigerant piping or electrical wiring at the time of piping work.

According to claim 4, the center position of the width dimension of the concave portion is provided at a position far from the blower cover side than the center position in the depth direction of the outdoor unit or at a position farther from the center position in the depth direction of the compressor, so that when the operator lifts and transports it, Since the center of gravity of the outdoor unit is located between the hand holding the handle and the boat in contact with the blower cover side, it is easy to lift because no load is applied only to the hand, and when the outdoor unit is inclined, the plate thickness is increased. Since strength is secured without distortion, distortion and deformation of the box due to the weight of the outdoor unit can be suppressed.

According to claim 5, the lower end of the concave portion and the lower end of the handle portion is 15 mm or more and less than half of the height dimension of the side portion of the box body, the effect of the strength improvement by the concave portion can be sufficiently obtained, Even when lifted in a photographic state, it is possible to suppress the occurrence of torsional deformation in the box by the weight of the outdoor unit.

According to claim 6, the effect corresponding to the 1st subject which can provide the outdoor unit which is easy to grasp, without protruding a carrying handle almost to the left and right of a box top plate can be acquired. That is, since the vertical height dimension H3 of the concave portion is 15 mm or more larger than the vertical dimensions H2 and H4 of the handle portion, the fingertip is placed in the vertical direction (at least in the first direction between the surface of the concave portion and the inner surface of the handle portion). The joint can form a space that can be inserted in the vertical direction). Thus, at least the first joint is inserted in the vertical direction so that the fingertip tip supports the upper back surface side of the upper surface member, and the middle of the fingertip supports the lower end of the handle portion, and the palm side It is also easy to counter this against a large load that pushes the joint of the finger downward to increase the bending angle of the joint.

In addition, since the recess is recessed inwardly of the box body, it is not necessary to protrude the handle largely to form a space for inserting the fingertip. Thereby, an external dimension can be made small and the number of loading to a conveyance vehicle, and the storage number of a storage warehouse can be increased.

According to claim 7, the center position in the depth direction of the concave portion is provided at a position far from the center position in the depth direction of the outdoor unit or the center position in the depth direction of the compressor from the blower cover side, so that when the operator lifts and transports, the center of gravity Since it is located between the hand holding the handle and the boat in contact with the blower cover side, the load is not applied only to the hand, so it is easy to lift, and the strength is secured without increasing the plate thickness even if the outdoor unit is inclined when contacting the boat. Therefore, distortion and deformation of the box due to the weight of the outdoor unit can be suppressed.

According to claim 8, the vertical dimension of the handle portion is a vertical dimension (H2) equivalent to the vertical dimension (H1) of the end of the upper member, the fingertip between the surface of the recess and the inner surface of the handle portion. It is possible to form a space insertable in the vertical direction, and at the same time, the engagement of the fingertip on the handle is very well stabilized and can be held.

According to claim 9, the vertical dimension of the handle is smaller than the vertical dimension H1 of the end of the upper surface member, and is 1/2 or more of the vertical dimension H4, so that the face of the recess and the inner surface of the handle A space in which the fingertips can be inserted in the vertical direction can be formed therebetween, and the latching of the fingertips on the handle portion can be sufficiently secured.

According to Claim 10, since the handle was formed so that it might not protrude from the outer peripheral surface of the short side edge part of an upper surface member, an external dimension can be made small.

According to claim 11, since the vertical dimension (H2) of the handle portion is 20 mm to 40 mm, the finger tip front end supports the upper back surface side of the upper member, while the middle of the finger tip supports the lower end of the handle part. I can fully hold it. For example, in the case of 20 mm, the handle can be reliably held by being inserted from the fingertip to the vicinity of the first joint in the finger insertion space. In addition, in the case of 40 mm, the finger insertion space is inserted from the fingertip to the vicinity of the second joint to contact the handle with a large area for reliable holding. In addition, since the contact with a large area, the weight to the finger is widely dispersed in the contact surface of the finger, the load burden is smaller than in the case of 20 mm, it can be held more reliably.

According to claim 12, since the vertical dimension (H3) of the concave portion concave inwardly into the box body is 40 mm or more to less than half of the vertical height dimension of the box body, bend the fingers in an unobtrusive manner to hold the handle Since the outdoor unit can be lifted, it is easy to walk or climb stairs in the lifted state. In addition, a small outdoor unit can be carried alone.
