  The conventional outdoor unit described in Patent Documents 1 to 4 described above is a box when the outdoor unit is lifted by securing strength by combining the shape of the handle portion of the box body upper plate and the shape of the side surface portion of the box body. To prevent deformation of the area around the handle on the top plate of the body and the side surface of the box body, and to ensure the strength of the box when stacking outdoor units when loading and transporting in a vehicle or storing in a warehouse It is not considered to form. Therefore, it is necessary to increase the thickness of the box upper surface plate and the side surface portion of the box body or to reinforce the structure with an internal structure.

  Furthermore, since the conventional outdoor units of Patent Documents 1 to 3 are formed so that the transport handle protrudes left and right on a part of the box body upper plate, the outer dimensions of the outdoor unit become large. Have a problem. For this reason, there is a problem that not only a large amount of material is required, but also the number of units loaded in a vehicle for transportation or the number of units stored in a warehouse decreases accordingly.

  The present invention is intended to solve the above-mentioned problems, and the first problem is that the outer dimensions of the outdoor unit are increased by making the carrying handle hardly protrude to the left and right of the box top plate.

  In the outdoor unit for an air conditioner according to a third aspect, the compressor according to the first aspect is provided on one end side in the left-right direction of the box body.

  The outdoor unit of the air conditioner according to claim 4 is a position in which the center position of the width dimension of the recess according to claim 1 is farther from the blower cover side than the center position in the depth direction of the outdoor unit or in the depth direction of the compressor. It is provided in a position farther from the blower cover side than the center position.

  The outdoor unit of the air conditioner according to claim 5 has a space between the lower end of the recess according to claim 1 and the lower end of the handle portion of 15 mm or more and within half the height dimension of the side surface portion of the box body. .

  In order to solve the second problem, the present invention includes a compressor, a heat exchanger, and a blower inside a box, and the box has a bottom surface portion and a side surface portion, and a top surface is opened. It is composed of a main body and an upper surface member attached so as to close the opening on the upper surface of the box main body, and the upper surface member has a handle for transportation integrally formed at an end portion on the short side, The side surface portion of the box body has a concave portion recessed in the box body at a position corresponding to the handle portion, and the vertical height dimension (H3) of the concave portion is greater than the vertical dimension (H2, H4) of the handle portion. Is an outdoor unit of an air conditioner that is larger than 15 mm and within half the height of the side surface of the box body.

  The outdoor unit of the air conditioner according to claim 7 is such that the center position in the depth direction of the recess according to claim 6 is greater than 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. Is also provided at a distant position.

  The outdoor unit of the air conditioner according to claim 8 is such that the handle according to claim 6 has a vertical dimension (H2) whose vertical dimension is equivalent to the vertical dimension (H1) of the end of the upper surface member. is there.

  The outdoor unit of the air conditioner according to claim 9 is such that the handle according to claim 6 has a vertical dimension smaller than a vertical dimension (H1) of the end portion of the upper surface member and 1/2 or more. The vertical dimension (H4).

  The outdoor unit of the air conditioner according to claim 10 is characterized in that the handle portion according to claim 6 is formed at a part of the short side end of the top member and the outer periphery of the short side end of the top member. It is formed so as not to protrude from the surface.

  The outdoor unit of the air conditioner according to claim 11 has a vertical dimension (H2, H4) of a handle portion formed integrally with an end portion of the upper surface member according to claim 6 in a range of 20 mm to 40 mm. is there.

  The outdoor unit of the air conditioner according to claim 12 is characterized in that the vertical dimension (H3) of the concave portion recessed in the box body according to claim 6 is from 40 mm or more to half the vertical height dimension of the box body. It is as follows.

  According to the present invention, the concave portion formed integrally with the side surface portion of the box body has a top end surface recessed integrally with the upper end surface of the flat portion adjacent to the concave portion inside the box body, The concave portion and the side portion provided with the concave portion can increase the strength against the load, and the handle is formed by forming a finger insertion space between the concave portion and the grip portion of the upper surface member. By combining the shape of the handle portion and the concave shape of the side surface portion of the box body with little protrusion to the left and right of the box top plate, the outer dimensions of the outdoor unit are not increased and the strength of the box body is increased. The effect corresponding to the 1st subject that the outdoor unit which can secure can be provided is acquired.

  According to the second aspect, the upper end surface of the recess is recessed so as to be integrated with the upper end surface of the flat portion adjacent to the recess, and the upper end surface of the recess is bent in the horizontal direction from the vertical portion of the recess. By adopting the shape, the strength is increased with respect to the load applied to the outdoor unit, particularly with respect to the load in the horizontal direction and the load in the oblique direction, and deformation of the box can be suppressed.

  According to the third aspect, since the compressor is provided on one end side in the left-right direction of the box body, an effect can be obtained even when only the compressor side having a large load is configured as in the first aspect. This is because, when a recess is provided on one end side in the left-right direction of the box body, one of the left and right sides of the side surface portion of the box body, the side surface portion on the side where the blower cover adjacent to this surface is provided, heat exchange The improvement by the synergistic effect of the combination strength with the side surface portion on the side of the vessel, the upper surface member, and the bottom surface member on which the compressor is placed can be expected.

  When a plurality of such outdoor units are stacked, they may be stacked so that the compressor side of another outdoor unit is stacked on the compressor side.

  In addition, the outdoor unit configured as described above can be used to mount refrigerant pipes, electrical wiring, and the like by an operator on the compressor side of the outdoor unit during piping work.

  According to claim 4, the center position of the width dimension of the recess is provided at a position farther 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. As a result, the center of gravity of the outdoor unit is located between the hand hung on the handle and the stomach abutted on the blower cover when the operator lifts and carries the load, so that no load is applied only to the hand. Even if the outdoor unit tilts when it is easy to hold and abuts on the stomach, the strength is ensured without increasing the plate thickness, so that distortion and deformation of the box due to the weight of the outdoor unit can be suppressed.

  According to claim 5, the space between the lower end of the recess and the lower end of the handle portion is 15 mm or more and within half the height dimension of the side surface portion of the box body, so that the effect of improving the strength by the recess is sufficiently obtained. Thus, even when the outdoor unit is lifted in an inclined state, it is possible to suppress the occurrence of twisting deformation in the box due to the weight of the outdoor unit.

  According to the sixth aspect, an effect corresponding to the first problem can be obtained in that an outdoor unit that is easy to hold can be provided without causing the carrying handle to protrude almost to the left and right of the box body upper plate. That is, since the vertical height dimension (H3) of the concave portion is 15 mm or more larger than the vertical dimension (H2, H4) of the handle portion, the fingertip is placed between the concave surface and the inner side surface of the handle portion. A space that can be inserted in the vertical direction (at least the first joint is vertical) can be formed. In this way, by inserting at least the first joint in the vertical direction, the tip of the fingertip supports the upper back side of the upper surface member and the middle of the fingertip supports the lower end of the handle portion. It becomes easy to withstand a large load that pushes down the finger joint on the palm side rather than supporting it to open the bending angle of the joint.

  Moreover, since it has the recessed part dented inside the box, in order to form the space which inserts a fingertip, it is not necessary to project a handle large. As a result, the external dimensions can be reduced, and the number of vehicles loaded on the transport vehicle and the number of storage warehouses can be increased.

  According to the seventh aspect, the center position in the depth direction of the recess is provided at a position farther from the blower cover side than the center position in the depth direction of the outdoor unit or the center position in the depth direction of the compressor. Since the center of gravity is located between the hand hung on the handle and the stomach abutted on the blower cover side, it is easy to hold without applying a load to the hand and touches the stomach. Even when the outdoor unit is tilted when contacting, the strength is ensured without increasing the plate thickness, so that the distortion and deformation of the box due to the weight of the outdoor unit can be suppressed.

  According to the eighth aspect of the present invention, the vertical dimension of the handle portion is the vertical dimension (H2) equivalent to the vertical dimension (H1) of the end portion of the upper surface member. A space in which a fingertip can be inserted in the vertical direction can be formed between the inner surface and the inner surface of the fingertip, and the hook of the fingertip on the handle can be held very well and stably.

  According to the ninth aspect of the present invention, the vertical dimension of the handle is smaller than the vertical dimension (H1) of the end portion of the upper surface member and is a vertical dimension (H4) of 1/2 or more. A space in which the fingertip can be inserted in the vertical direction can be formed between the surface of the recess and the inner side surface of the handle, and sufficient engagement of the fingertip with the handle portion can be secured.

  According to the tenth aspect, since the handle is formed so as not to protrude from the outer peripheral surface of the end portion on the short side of the upper surface member, the outer dimension can be reduced.

  According to the eleventh aspect, since the vertical dimension (H2) of the handle portion is 20 mm to 40 mm, the tip of the fingertip supports the back side of the upper surface of the upper surface member and the middle of the fingertip supports the lower end portion of the handle portion. As a result, the handle can be held sufficiently. For example, in the case of 20 mm, the handle can be firmly held by being inserted into the finger insertion space from the fingertip to around the first joint. In the case of 40 mm, the finger insertion space can be inserted from the fingertip to the vicinity of the second joint, and can be held firmly by contacting the handle with a large area. Moreover, since the contact is made in a large area, the load on the finger is widely distributed on the contact surface of the finger, and the load burden is further reduced as compared with the case of 20 mm, so that the finger can be held more firmly.

  According to the twelfth aspect, since the vertical dimension (H3) of the recess recessed inward of the box body is from 40 mm or more to half or less of the vertical height dimension of the box body, the finger is shaped into a reasonable shape. Since the outdoor unit can be lifted by bending and holding the handle, walking in the lifted state and elevating the stairs are facilitated. In addition, a small outdoor unit can be carried alone.

  Hereinafter, the present invention will be described with reference to the drawings.

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

  FIG. 1 is a cross-sectional view of an outdoor unit handle portion of an air conditioner showing a first embodiment of the present invention. FIG. 2 is a cross-sectional view of a handle portion for explaining a dimensional relationship of a handle portion of the outdoor unit. FIG. 4 is a partial perspective view showing a concave portion of the box body at a position corresponding to the handle portion of FIG. 2, FIG. 4 is a partial cross-sectional view of the top member of the outdoor unit, and FIG. 5 is a side partial view showing the handle portion of FIG. 6 is an overall perspective view of the outdoor unit when the top member is opened and seen from diagonally upward on the right side, FIG. 7 is an overall perspective view of the outdoor unit when the top surface member of the outdoor unit is opened and seen diagonally from the left side, and FIG. FIG. 9 is a right side view of the outdoor unit, FIG. 10 is a perspective view of the upper surface member of the outdoor unit as viewed from the upper right side, and FIG. 11 is a handle portion of the upper surface member of FIG. 10 viewed from the back side. It is a fragmentary perspective view.

  As shown in FIGS. 6 to 9, the outdoor unit of the present embodiment forms a box body 1 with a bottom surface portion and four side surface portions, and the upper surface member 2 closes the opening on the top surface of the box body 1. It constitutes the entire box. A blower 6, a heat exchanger 7, a compressor 8 and the like are built in the box. A blower cover 5 is provided on the front surface of the blower 6. In the outdoor unit, the handle used for transportation is arranged inside the box so as to form the finger insertion space 3 at the positions facing the handle portions 2a and 2d of the upper surface member 2 and the handle portions 2a and 2d. It is comprised by the recessed parts 1b and 1g formed so that it might dent.

  The handle portion 2 a and the handle portion 2 d are formed integrally with the end portion on the short side of the upper surface member 2. The handle portion 2a and the handle portion 2d are formed by folding the plate of the end portion 2b of the upper surface member 2 inward as shown in FIGS. The side surface of the end portion 2b of the handle portion 2a and the handle portion 2d and the side surface of the adjacent end portion 2b are formed on the same plane.

  When the upper surface member 2 is engaged with the box body 1, the screw hole 1c and the screw hole 2c are overlapped to communicate with each other. A screw (screw 4 shown in FIG. 5) is screwed into the overlapped hole and fixed integrally. The structure of the handle in this integrally fixed state is as shown in FIGS. 1 and 2 which are partial sectional views and FIG. 5 which is a partial side view. That is, the handle portion 2 a and the handle portion 2 d are formed at the end portion on the short side of the upper surface member 2. 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 of the side surface of the box main body 1. FIG. The concave portion 1b and the concave portion 1g are formed so as to be recessed inside the box body by plastic molding using a press machine or the like.

  The heavy compressor 8 is provided at the right end of the box body 1 as shown in FIGS. The concave portion 1b is provided on the side where the heavy compressor 8 is provided. Further, the recess 1g is provided on the opposite side surface portion where the compressor 8 is provided. Therefore, as shown in FIG. 3, the concave portion 1b was formed by plastic molding with the width dimension W1 of the inner portion of the concave portion and the width dimension W2 of the opening portion of the concave portion increased to increase the side strength of the box. In the example, the width dimension W1 of the inner part of the recess 1b is 65 mm, and the width dimension W2 of the opening is 85 mm. Thereby, four fingertips other than the thumb can be inserted to the back without difficulty.

  Since the width dimensions W1 and W2 are formed large, not only the side surface strength of the box is increased, but also the finger of the hand is fully inserted into the finger insertion space 3 as shown in FIG. 2a can be held securely.

  On the other hand, since the weight on the opposite side where the compressor 8 is provided is light, a large load is not applied to the hand even if the outdoor unit is lifted by placing a hand on the handle portion 2d. For this reason, the concave portion 1g formed at the position facing the handle portion 2d does not need to insert more fingers than the concave portion 1b, so the size of the plastic forming of the concave portion 1g is made smaller than that of the concave portion 1b. Since the concave portion 1g on the opposite side provided with the compressor 8 can be made smaller than the concave portion 1b, as shown in FIG. 7, the outdoor unit is enlarged so as to be recessed in the space formed by the bent portion of the heat exchanger 7. I devised not to.

  As shown in FIGS. 1, 2, 6, and 7, a reinforcing portion 1 a is formed by protruding from the side surface of the outdoor unit on the compressor 8 side. This suppresses the occurrence of bending when an external force or an outdoor unit is stacked and its weight is added to the outdoor unit.

  The upper end 1d on the side surface of the box body 1 has its upper end surface bent into a curved surface. This increases the side strength of the box and makes it difficult to distort the side of the box. Even when bent at a right angle, the same level of strength securing effect can be obtained. The upper end surface 1e of the recess 1b is recessed inward of the box so as to be continuous with the upper end surface of the flat portion of the side surface portion.

  The box body 1 is made by bending the side surface at a right angle. However, when the box body 1 is bent at a right angle, the upper end 1d is bent into a curved surface. I can do it. As a result, the entire box body may be deformed. In order to prevent this, as shown in FIG. 3, the curved portion 1d at the upper end of the portion bent at a right angle is cut out to form a cutout portion 1f.

  The said outdoor unit can acquire the effect of the Example corresponding to the 1st subject by setting it as the structure of the following Examples.

  For example, the upper surface member 2 has a handle 2a for transportation formed integrally with the end 2b on the short side, and the side surface of the box body 1 is integrally formed at a position corresponding to the handle 2a. A recess 1b formed and recessed inward of the box and a flat portion adjacent to the recess 1b. The recess 1b has an upper end surface 1e integrated with an upper end surface of the flat portion adjacent to the recess 1b. It is recessed in the box so as to be continuous, and the upper surface member 2 is placed on the upper end surface 1e of the concave portion 1b. Between the concave portion 1b and the handle portion 2a of the upper surface member 2, there is a finger insertion. The space 3 is formed to constitute a handle.

  Although not shown, when the upper surface member 2 is placed on the upper end surface 1e of the concave portion 1b, the inclusions are interposed therebetween, so that the gap can be reduced and rain can be applied to severe wind and rain. Intrusion to the inside is prevented, and even when an installation worker gets on the upper surface member 2, the upper surface 1e of the concave portion 1b is not directly pressed against the upper surface 1e. It can prevent remaining on the member 2.

  The upper end portion 1d of the side surface of the box body 1 has an upper end surface that is bent into a curved surface. This improves the strength and makes it difficult to cause distortion and deformation with respect to a horizontal force. The shape of the part can be formed in a predetermined shape. Even when bent at a right angle instead of a curved surface, the same effect of securing strength as when bent into a curved surface can be obtained.

  In addition, the concave portion 1b that is integrally formed with the side surface portion of the box body 1 by a press machine or the like is recessed inside the box body so that the upper end surface 1e thereof is continuous with the upper end surface of the flat portion of the side surface portion. Yes. By doing in this way, the side part provided with this recessed part 1b can enlarge the intensity | strength with respect to the load of a perpendicular direction. By providing the recess 1b, deformation can be suppressed even when a plurality of outdoor units are stacked. In this case, the effect can be obtained only on the side of the heavy compressor 8 side.

  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 might continue integrally. Since the box strength is thereby increased, it is possible to get on the upper surface member 2 of the outdoor unit and perform the installation work of the refrigerant pipe and the electric wiring during the work of the refrigerant pipe and the electric wiring. Furthermore, since the upper end surface of the recess 1b is formed so as to be continuous with the upper end surface of the flat portion of the side surface portion, there is no gap in the handle or the gap is reduced. This prevents wind and rain from entering the interior and prevents electrical components from being damaged.

  The upper end surface 1e of each of the concave portion 1b and the flat portion adjacent to the concave portion 1b and the portion where the upper end surface 1e is integrally formed have a shape bent in the horizontal direction from the vertical portion.

  As described above, the upper end surface 1e of each of the concave portion 1b and the flat portion adjacent to the concave portion 1b and the portion where the upper end surface 1e is integrally formed have a shape bent in the horizontal direction from the vertical portion. As a result, the strength is increased with respect to the load applied to the outdoor unit, particularly against the load in the horizontal direction and the load in the oblique direction, and the deformation of the box can be suppressed. In addition, since the upper end surface 1e is bent in the horizontal direction, the upper surface member 2 is used when the outdoor unit is stacked or when a person rides on the outdoor unit to perform piping work of the air conditioner. Is strongly pressed against the upper end surface 1e of the box body, the surface contact with the upper surface member 2 makes it difficult for the upper surface member 2 to be pressed and deformed.

  Furthermore, the upper surface member 2 is placed on the upper surface 1e of the recess 1b by contacting the lower surface of the upper surface member 2 or interposing an inclusion, thereby enhancing the sense of unity between the two members and between the two members. The gap can be reduced to prevent wind and rain from entering the interior and damaging electrical components. In addition, by interposing an inclusion between the upper end surface 1e of the recess 1b and the lower surface of the upper surface member 2, when the outdoor unit is stacked or a person gets on the outdoor unit, piping work of the air conditioner Even if the upper surface member 2 is strongly pressed against the upper end of the box body by performing the above-described operations, it is not directly pressed.

  Next, according to the configuration of the following embodiment, the effect of the embodiment corresponding to the second problem can be obtained.

  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 portion 2a is the side where the heavy compressor 8 is provided, it is preferable to increase the bending thickness dimension D2. However, when the bending thickness dimension D2 is increased, the dimension D1 of the recess 1b that forms the finger insertion space 3 must also be increased. Therefore, the bending thickness dimension D2 is set to 3 mm as the minimum necessary size that can reliably receive the load on the finger during transportation. Since the dimension D1 of the concave portion 1b is 16 mm in the embodiment, the substantial insertion dimension of the finger is D1−D2 = 13 mm.

  The bent portions of the handle portion 2a and the handle portion 2d are not necessarily formed on the same plane as the other adjacent portions of the end portion of the upper surface member 2. If it is a small dimension of about several millimeters, for example, about 3 mm of the bending thickness dimension D2, it is small and partial even if it protrudes from the side of the box, so there is almost no problem in the external dimensions. In other words, since it is almost absorbed by the thickness of the packaging material, there is no need to increase the overall size of the packaging material, and there is almost no adverse effect such that the number of loaded vehicles on the transport vehicle is reduced. Can be. From this, the portion of the grip portion 2a shown in FIGS. 1 and 2 that is bent toward the finger insertion space 3 is partially molded so as to protrude outward from the box by about 3 mm of the bent thickness dimension D2. You may do it. In this way, the dimension D1 of the recess 1b does not need to be 16 mm, and can be 13 mm. Therefore, the size of the box can be reduced by 3 mm on one side, and can be reduced by 6 mm on both sides, that is, the entire box. is there. However, when projecting the bent portion to the outside of the box, the vertical height dimension H2 of the handle portion 2a is preferably set to 20 mm or more. That is, when the vertical height dimension H2 of the handle portion 2a is less than 20 mm, there is a high probability that the finger will not be in the vertical direction (including an inclination of 45 degrees or more) due to the load applied to the finger when the outdoor unit is lifted. Accordingly, when the vertical height dimension H2 of the grip portion 2a is less than 20 mm, the portion bent toward the finger insertion space 3 is left protruding toward the finger insertion space 3 and is easily caught on the finger and is difficult to slide off. It is preferable to facilitate transportation. 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 is the same dimension except a plate | board thickness dimension. The vertical height dimension H3 of the recess 1b is 65 mm. Due to the reinforcing effect of the side plate by the concave portion 1b of this example, when the box strength was about the same as the thickness of the conventional 0.8 mm, the plate thickness could be 0.6 mm.

  Moreover, the said recessed part 1b is provided in the side in which the compressor 8 with a heavy weight was provided. Therefore, as shown in FIG. 3, the concave portion 1b was formed by plastic molding with the width dimension W1 of the inner portion of the concave portion and the width dimension W2 of the opening portion of the concave portion increased to increase the side strength of the box. In the example, the width dimension W1 of the inner part of the recess 1b is 65 mm, and the width dimension W2 of the opening is 85 mm. Thereby, four fingertips other than the thumb can be inserted to the back without difficulty.

  Since the width dimensions W1 and W2 are formed large, not only the side surface strength of the box is increased, but also the finger of the hand is fully inserted into the finger insertion space 3 as shown in FIG. 2a can be held securely. Accordingly, even on the side of the compressor 8 having a heavy weight, the handle portion 2a can be lifted while being firmly held by the fingers of the hand, so that the fingers can sufficiently withstand the load and can be easily transported.

  In other words, a force that pushes down downward in the vertical direction by a large load acts on the finger joint on the palm side relative to the portion supporting the lower end of the handle portion 2a. However, since the joint bent as shown in FIG. 1 is bent with the tip of the finger substantially upward in the vertical direction, it is easy to counter the force (load) pushed down in the vertical direction. It becomes easy to prevent the folding angle from opening.

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

  The space between the lower end of the concave portion 1b and the lower end of the handle portion 2a is preferably 15 mm or more and within half the height of the box body 1. This is a range in which the effect of preventing deformation of the box can be obtained. When the height of the box body 1 is more than half of the height, the load of the heavy compressor 8 is increased when the outdoor unit is lifted in an inclined state. This is because the effect of suppressing the deformation of the box body is almost eliminated. In other words, the strength against the load in the oblique direction or the strength against the load in the twist direction is increased at the lower end portion of the recess 1b and the upper end surface 1e of the recess, but when the height is more than half of the height of the box body 1, the oblique direction Or the effect of the strength improvement with respect to the load of a twist direction will become small.

  The upper surface member 2 has a handle portion 2a for transportation formed integrally with the end portion 2b on the short side, and the side surface portion of the box body 1 is a recess recessed inward of the box body at a position corresponding to the handle portion 2a. 1b, and the vertical height dimension H3 of the concave portion 1b is 15 mm or more larger than the vertical dimension H2 of the handle portion 2a and less than half the height dimension of the box body 1.

  Since the vertical height dimension H3 of the concave portion 1b is set to be 15 mm or more larger than the vertical dimension H2 of the handle portion 2a, the fingertip is placed vertically between the surface of the concave portion 1b and the inner side surface of the handle portion 2a. A space in which at least the first joint can be inserted in the vertical direction can be formed in the direction. Thus, by inserting at least the first joint in the vertical direction, the tip of the fingertip supports the upper surface back side of the upper surface member 2, and the middle of the fingertip supports the lower end of the handle portion 2a. It is easy to resist a load in a direction in which the finger joint on the palm side is pushed down rather than supporting the lower end, that is, a large load in a direction in which the bending angle of the bent joint is greatly opened.

  As a result, even with a heavy load, the fingertip can be transported without difficulty compared to an outdoor unit that supports the handle portion 2a at an angle of less than 45 degrees with respect to the horizontal direction, that is, for example, a customer. It is also easy to carry up the stairs of the house to the second floor.

  It should be noted that a depth dimension is required so that the fingertip can be largely inserted in the horizontal direction so that the fingertip can be transported without difficulty even if it is supported in a state close to the horizontal direction. In the case of a standard outdoor unit with a weight of 35 kg, it was confirmed that a depth dimension that can be inserted beyond the first joint from the tip of the fingertip is required. In the experimental example, at least 25 mm was required, and desirably 30 mm or more. Thus, when it is going to make a big depth dimension in a horizontal direction, it becomes impossible to form the recessed part 1b by a plastic molding process so that the upper end part of the side surface of a box may be dented inside, and another component will be needed. In addition, since the vertical dimension H2 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 30 mm or more away from the handle portion 2a, and the upper surface member 2 may be deformed. There is. In order to prevent this deformation, it is necessary to increase the plate thickness or to ensure the strength by partially protruding the handle portion 2a outward as in the prior art. Therefore, the parts cost becomes higher by that amount, and it has the same problem as the above-described prior art. In addition, it is difficult to secure a strength sufficient for the stacking of outdoor units, which is an object of the present invention.

  The vertical height dimension H3 of the recess 1b recessed inside the box is made 15 mm or more larger than the vertical dimension H2 of the handle part 2a, thereby forming a space for inserting a fingertip without increasing the depth dimension. Because it is possible, there is no need to protrude the handle. As a result, the outer dimensions can be reduced, and the packaging box such as a cardboard box can be reduced, which leads to resource saving. Moreover, since the external dimensions are small, the number of vehicles loaded on the transport vehicle and the number of storage warehouses can be increased.

  When the operator lifts and carries the concave portion 1b in the depth direction from the fan cover side at a position farther from the blower cover side than the center position in the depth direction of the outdoor unit or the center position in the depth direction of the compressor 8. In addition, the center of gravity is located between the hand hung on the handle and the stomach that is in contact with the blower cover. Even if the machine is tilted, the strength is ensured without increasing the plate thickness, so that the distortion and deformation of the box due to the weight of the outdoor unit can be suppressed.

  The handle has a vertical dimension (H2) equivalent to the vertical dimension (H1) of the end 2b of the upper surface member 2, and thus the surface of the recess and the inner surface of the handle During this, a space in which the fingertip can be inserted in the vertical direction can be formed, and the hook of the fingertip on the handle portion can be held very well and stably.

  Since the vertical dimension of the handle is smaller than the vertical dimension (H1) of the end 2b of the upper surface member 2, and the vertical dimension (H4) is 1/2 or more, the surface of the concave portion A space in which the fingertip can be inserted in the vertical direction can be formed between the handle and the inner surface of the handle, and the fingertip can be sufficiently secured to the handle portion.

  The handle is formed at a part of the short side end portion 2b of the upper surface member 2 so that a space into which a fingertip can be inserted is formed between the surface of the recess 1b and the inner side surface of the handle, and By forming the upper surface member 2 so as not to protrude from the outer peripheral surface of the short side end portion 2b, the outer dimensions can be reduced.

  The vertical dimension (H2, H4) of the grip portion 2a formed integrally with the end portion 2b of the upper surface member 2 was set to a 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 hold the handle sufficiently. For example, in the case of 20 mm, the handle can be firmly held by being inserted into the finger insertion space from the fingertip to around the first joint. In the case of 40 mm, the finger insertion space can be inserted from the fingertip to the vicinity of the second joint, and can be held firmly by contacting the handle with a large area. Moreover, since the contact is made in a large area, the load on the finger is widely distributed on the contact surface of the finger, and the load burden is further reduced as compared with the case of 20 mm, so that the finger can be held more firmly.

  The vertical dimension H3 of the concave portion 1b recessed inside the box was set to be 40 mm or more and half or less of the vertical height of the box. By setting the thickness to 40 mm or more, the finger can be bent into a comfortable shape and inserted into the finger insertion space in a substantially vertical direction, so that the outdoor unit can be lifted while holding the handle without difficulty. This facilitates walking and raising / lowering the stairs while the outdoor unit is lifted. In addition, a small outdoor unit can be carried alone.

  FIG. 12 is a cross-sectional view of an outdoor unit handle portion of an air conditioner showing a second embodiment of the present invention, and FIG. 13 is a perspective view of an upper surface member 2 ′ of the outdoor unit viewed from the upper right side.

  The upper surface member 2 'of the present embodiment has a handle portion 2a' for transportation formed integrally with the end portion 2b 'on the short side, and the side surface portion of the box body 1 is a position corresponding to the handle portion 2a'. Has a recessed portion 1b recessed inward of the box body, the vertical height dimension H3 of the recessed portion 1b being 15 mm or more larger than the vertical dimension H4 of the handle portion 2a 'and not more than half of the height dimension of the box body 1 I made it. Specifically, the vertical dimension H1 of the end 2b 'of the upper surface member 2' is 20 mm, and the vertical height H4 of the handle 2a 'is 11 mm, which is more than half the vertical dimension H1. The reason why the vertical height H4 of the handle 2a 'is 11 mm is that, as shown in the drawing, the tip of the handle 2a' is bent toward the finger insertion space 3 'to improve the hooking with the finger. The depth dimension of the finger insertion space 3 ′ is set to about 15 mm, and the vertical height dimension H3 of the concave portion 1b is formed to be 15 mm or more larger than the vertical dimension H4 of the grip portion 2a ′. This is because it is inserted in the space 3 ′ in the vertical direction.

  The height H3 in the vertical direction of the concave portion 1b of Example 2 is 65 mm, which is the same as that of Example 1, but sufficient supportability was confirmed even with the prototypes of 26 mm and 30 mm. However, the reinforcing effect of the side plate by the concave portion 1b recessed by plastic working is not sufficient as compared with the case of 65 mm, and when a person gets on the position directly above the concave portion 1b of the upper surface member 2 ′, The periphery of the concave portion 1b of the face plate was slightly distorted. Even if it is just enough to get on during the installation work, it can be said that the strength is sufficient, but when it is piled up and transported by a vehicle, it is assumed that a big impact will be applied, and when trying to obtain a very large reinforcing effect Has confirmed that it is desirable that it is 45 mm or more. As a result, a space in which the fingertip can be inserted in the vertical direction and at least the first joint can be inserted in the vertical direction can be formed between the surface of the recess 1b and the inner surface of the handle portion 2a '. As described above, since at least the first joint can be inserted in the vertical direction, the tip of the fingertip can support the back surface of the upper surface of the upper surface member 2 ', and the middle of the fingertip can support the lower end portion of the handle portion 2a' in a state where it is difficult to slide.

  As a result, even when the load is large, the fingertip is transported without difficulty compared to the conventional outdoor unit that does not protrude the handle and supports the handle portion 2a at an angle of less than 45 degrees with respect to the horizontal direction. For example, it can be easily transported upstairs to the second floor of the customer's house.
