[0008] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the idea of ​​this disclosure, an air conditioner's outdoor unit had an outlet grill installed at the front of the propeller fan of the housing. The outlet grill needs to be securely fixed so that people cannot touch it, in order to protect the propeller fan and the outdoor heat exchanger, which are rotating objects, and for safety reasons. One method of securely fixing the outlet grill is to weld the outlet grill to a plate on the front of the outdoor unit. However, there are problems in terms of cost, such as the need for welding equipment and the large number of production steps. Therefore, a cost-effective fixing method is to fix the outlet grille by engaging a claw with a plate on the front of the outdoor unit. However, the inventors discovered that the method of fixing the outlet grille by engaging the claws has the problem that the outlet grille may come off if, for example, the outdoor unit is dropped during transport, and in order to solve this problem, they have come up with the subject matter of the present disclosure. In view of the above, the present disclosure provides an outdoor unit that can reliably fix an outlet grille even if the outdoor unit is subjected to an impact.

[0009] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming more redundant than necessary and to facilitate understanding by those skilled in the art. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to the drawings. [1-1. Configuration] FIG. 1 is a perspective view of an outdoor unit 1 of an air conditioner according to the present embodiment. The outdoor unit of the present embodiment is connected to an indoor unit (not shown). The outdoor unit is equipped with a compressor, an expansion valve, an outdoor heat exchanger, etc., and the indoor unit is equipped with an indoor heat exchanger, etc. to form a refrigeration circuit. The air conditioner conditions the air of a space to be conditioned in which an indoor unit is provided by circulating a refrigerant through this refrigeration circuit. As shown in FIG. 1, the outdoor unit 1 of this embodiment is a so-called side-flow type or lateral-blowing type outdoor unit that draws in air, exchanges heat between the air and a refrigerant flowing through an outdoor heat exchanger, and blows the air out from the other side.

[0011] The outdoor unit 1 includes a box-shaped housing 10 whose longitudinal direction extends along the left-right direction. In this embodiment, all of the components of the housing 10 are formed from steel plates. The housing 10 comprises a bottom plate 12 that forms the bottom surface of the housing 10, a top plate 14 that forms the top surface, a front plate 16 that forms the front surface, a back plate 18 that forms the back surface, a left side plate 11 that forms the left side surface, and a right side plate 13 that forms the right side surface.

[0012] An air outlet 15 is provided on a front panel 16 of the housing 10. The air outlet 15 is an opening through which air that has been taken into the housing 10 and has been heat exchanged by the outdoor heat exchanger is discharged. Air intakes (not shown) are provided on the back panel 18 and the left side panel 11. These air intakes are openings through which air is drawn from the outside of the housing 10 to the inside.

[0013] An air outlet grill 20 is attached to the air outlet 15. The air outlet grill 20 is made of, for example, a resin material, and is formed in a mesh shape that allows air to pass through. Fig. 2 is a cross-sectional view showing a fixed state between outlet grill 20 and front plate 16 in embodiment 1. Fig. 3 is a perspective view showing a fixed state between outlet grill 20 and front plate 16 in embodiment 1. 2, a locking member 21 is formed to protrude from the upper part on the rear side of the outlet grill 20. The locking member 21 is formed in a flat plate shape extending in the width direction of the outlet grill 20. For example, two locking members 21 are provided at both ends of the upper part of the outlet grill 20. The engaging member 21 has a tapered engaging claw 22 formed at its tip end, which protrudes in the vertical direction and has a tapered tip end. The engaging claws 22 each have an engaging surface 23 facing the outlet grill 20. The locking claw 22 on the lower surface side of the locking member 21 functions as a locking portion in the present disclosure.

[0014] An engaging opening 30 for receiving an engaging member 21 is formed at the upper edge of the air outlet of the housing 10 . The locking opening 30 has a flange portion 31 protruding rearward from the front plate 16. The flange portion 31 is formed at the same time as forming the locking opening 30 by, for example, press working. The height dimension of the locking opening 30 in the vertical direction is formed to be slightly larger than the thickness dimension of the locking claw 22 in the vertical direction.

[0015] [1-2. Effect] Next, the operation of the first embodiment will be described. In this embodiment, first, the locking members 21 of the outlet grille 20 are inserted into the locking openings 30 of the front panel 16 . In this state, the locking claws 22 of the locking members 21 are locked to the flange portions 31 of the locking openings 30, so that the outlet grille 20 can be fixed to the front panel 16 of the housing 10.

[0016] If the outdoor unit 1 is dropped during transportation, an upward force is applied to the outlet grille 20 due to the impact caused by the drop. In this embodiment, the locking member 21 is inserted into the locking opening 30 and the locking claw 22 is locked to the flange portion 31. Therefore, when an upward force is applied to the exhaust grill 20, the upper surface of the locking member 21 abuts against the upper part of the flange portion 31, and the upper locking claw 22 is positioned above the flange portion 31. In this state, the locking surface 23 of the upper locking claw 22 comes into contact with the inner end of the flange portion 31, so that the outlet grille 20 can be prevented from coming off.

[0017] [1-3. Effects, etc.] As described above, the outdoor unit 1 in this embodiment has an engagement opening 30 provided in the housing 10, an engagement member 21 provided in the outlet grille 20 to be inserted into the engagement opening 30, and engagement claws 22 provided on the upper and lower sides of the engagement member 21 to engage with the upper part of the engagement opening 30. As a result, the locking claws 22 of the locking members 21 are locked in the locking openings 30, so that the outlet grill 20 can be fixed to the front panel 16 of the housing 10. When an upward force is applied to the outlet grill 20 due to an impact such as when the outdoor unit 1 is dropped, the upper surface of the locking members 21 comes into contact with the upper part of the locking openings 30, and the locking claws 22 are positioned above the locking openings 30, so that the locking claws 22 can prevent the outlet grill 20 from coming off.

[0018] (Embodiment 2) Next, a second embodiment will be described. Note that the same parts as those in the above-described embodiments will be denoted by the same reference numerals. [2-1. Configuration] Fig. 4 is a cross-sectional view showing a fixed state between outlet grill 20 and front plate 16 in embodiment 2. Fig. 5 is a perspective view showing a fixed state between outlet grill 20 and front plate 16 in embodiment 2. As shown in Figs. 4 and 5, in this embodiment, locking member 21 has locking claws 22 formed only on the upper surface side.

[0019] A rib 24 is provided on the lower surface side of the locking member 21. The rib 24 is provided so as to extend in a direction substantially perpendicular to the outlet grill 20. The length dimension of the rib 24 from the tip of the locking member 21 is shorter than the locking surface 23 of the locking claw 22. It should be noted that the rib 24 provided on the locking member 21 functions as the locking portion of the present disclosure. In this embodiment, one rib 24 is provided at approximately the center in the width direction of the locking member 21. The rib 24 may be provided at a plurality of locations in the width direction. The other configurations are the same as those in the first embodiment.

[0020] [2-2. Effect] Next, the operation of the present disclosure will be described. In this embodiment, the locking members 21 of the outlet grille 20 are inserted into the locking openings 30 of the front panel 16 . In this state, the locking claws 22 of the locking members 21 are locked to the flange portions 31 of the locking openings 30, so that the outlet grille 20 can be fixed to the front panel 16 of the housing 10.

[0021] If the outdoor unit 1 is dropped during transportation, an upward force is applied to the outlet grille 20 due to the impact caused by the drop. In this embodiment, the locking member 21 is inserted into the locking opening 30 and the locking claw 22 is locked to the flange portion 31. Therefore, when an upward force is applied to the exhaust grill 20, the upper surface of the locking member 21 abuts against the upper part of the flange portion 31, and the upper locking claw 22 is positioned above the flange portion 31. In this state, the locking surface 23 of the upper locking claw 22 comes into contact with the inner end of the flange portion 31, so that the outlet grille 20 can be prevented from coming off.

[0022] In this embodiment, the locking claws 22 are formed only on the upper surface of the locking member 21, and ribs 24 are provided on the lower surface of the locking member 21. However, as mentioned above, the force on the outlet grill 20 due to the outdoor unit 1 being dropped, for example, is applied from above, so by providing the locking claws 22 on the upper surface of the locking member 21, it is possible to ensure the locking of the locking claws 22 with the flange portion 31.

[0023] [2-3. Effects, etc.] As described above, in the outdoor unit 1 in this embodiment, the rib 24 is provided on the lower surface side of the locking member 21. As a result, the locking claws 22 of the locking members 21 are locked in the locking openings 30, thereby fixing the outlet grille 20 to the front panel 16 of the housing 10. When an upward force is applied to the outlet grille 20 due to an impact such as when the outdoor unit 1 is dropped, the upper surface of the locking members 21 comes into contact with the upper part of the locking openings 30, and the locking claws 22 are positioned above the locking openings 30, so that the locking claws 22 can prevent the outlet grille 20 from coming off.

[0024] (Modification of the second embodiment) In the second embodiment, the ribs 24 are formed to extend in a direction substantially perpendicular to the outlet grille 20, but the present disclosure is not limited to this. Fig. 6 is a cross-sectional view showing a modified example of the fixed state between outlet grill 20 and front plate 16 in embodiment 2. Fig. 7 is a perspective view showing a modified example of the fixed state between outlet grill 20 and front plate 16 in embodiment 2. As shown in Figs. 6 and 7, even if the ribs 24 are formed so as to extend in the width direction of the outlet grille 20, the same functions and effects as those of the second embodiment can be obtained.

[0025] (Embodiment 3) Next, a third embodiment will be described. In addition, the same parts as those in the above-mentioned embodiments will be denoted by the same reference numerals. [3-1. Configuration] FIG. 8 is a perspective view showing a fixed state between the outlet grill 20 and the front panel 16 in the third embodiment. As shown in FIG. 8, in this embodiment, a locking member 21 has locking claws 22 formed only on its upper surface. The locking member 21 is arranged close to the upper surface of the locking opening 30, and is configured so that when the locking claw 22 of the locking member 21 is inserted into the locking opening 30, the locking surface 23 of the locking claw 22 abuts against the end surface of the flange portion 31.

[0026] Further, in the front plate 16, a positioning opening 40 is formed on one side of the locking opening 30 at a predetermined distance from the locking opening 30. A positioning member 41 is provided at a position corresponding to the positioning opening 40 of the air outlet grill 20. The positioning member 41 has an outer shape that follows the inner edge of the positioning opening 40. In this embodiment, the positioning member 41 is formed in a U-shaped cross section with an open lower surface.

[0027] [3-2. Effect] Next, the operation of the present disclosure will be described. In this embodiment, as shown in FIG. 8, the locking members 21 of the outlet grille 20 are inserted into the locking openings 30 of the front panel 16, and the positioning members 41 are inserted into the positioning openings . In this case, in this embodiment, the locking member 21 is arranged close to the upper surface of the locking opening 30, so that when the locking member 21 is inserted into the locking opening 30, the locking claw 22 of the locking member 21 gets caught in the locking opening 30.

[0028] However, since the upper surface of the locking claw 22 is tapered, when the locking member 21 is inserted into the locking opening 30, the tapered surface of the locking claw 22 fits along the upper edge of the locking opening 30, and the locking member 21 is pressed against the upper surface of the locking opening 30 and is inserted while bending downward. Thereafter, when the locking claw 22 passes through the locking opening 30 , the elastic force of the locking member 21 causes the locking surface 23 of the locking claw 22 to be locked to the flange portion 31 by returning the locking claw 22 to its original position. This allows the outlet grille 20 to be fixed to the front panel 16 of the housing 10.

[0029] Furthermore, if an upward force is applied to the outlet grill 20 due to the impact of the outdoor unit 1 being dropped during transportation of the outdoor unit 1, the positioning member 41 is inserted into the positioning opening 40, so the vertical position of the outlet grill 20 will not shift, and the engagement between the locking claws 22 of the locking member 21 and the flange portion 31 can prevent the outlet grill 20 from coming off.

[0030] [3-3. Effects, etc.] As described above, in the outdoor unit 1 in this embodiment, the housing 10 is provided with the positioning opening 40, and the outlet grille 20 is provided with the positioning member 41 to be inserted into the positioning opening 40. As a result, the locking claws 22 of the locking members 21 are locked in the locking openings 30, thereby fixing the exhaust grill 20 to the front panel 16 of the housing 10. Furthermore, even if an upward force is applied to the exhaust grill 20 due to an impact such as when the outdoor unit 1 is dropped, the position of the exhaust grill 20 in the up-down direction will not shift because the positioning members 41 are inserted in the positioning openings 40, and the locking claws 22 of the locking members 21 are locked in the flange portions 31, thereby preventing the exhaust grill 20 from coming off.

[0031] (Modification of the third embodiment) In the third embodiment, the positioning member 41 is formed to have a U-shaped cross section, but the present disclosure is not limited to this. FIG. 9 is a perspective view showing a modified example of the fixed state between the outlet grill 20 and the front panel 16 in the third embodiment. As shown in FIG. 9, even if the positioning member 41 is formed in a flat plate shape and a rib 42 similar to that of embodiment 2 is formed on the underside of the positioning member 41, the same action and effect as in embodiment 3 can be obtained.

[0032] (Embodiment 4) Next, a fourth embodiment will be described. In addition, the same parts as those in the above-mentioned embodiments will be denoted by the same reference numerals. [4-1. Configuration] FIG. 10 is a perspective view showing a fixed state between the outlet grill 20 and the front panel 16 in the fourth embodiment. 10, in this embodiment, the positioning member 41 is provided adjacent to an upper portion of the positioning opening 40. A second locking claw 43 is provided on the lower surface side of the positioning member 41. The locking member 21 is the same as that in the third embodiment.

[0033] [4-2. Effect] Next, the operation of the present disclosure will be described. In this embodiment, as shown in FIG. 10 , the locking member 21 of the outlet grill 20 is inserted into the locking opening 30 of the front panel 16, and the positioning member 41 is inserted into the positioning opening 40, thereby fixing the outlet grill 20 to the front panel 16 of the housing 10.

[0034] Furthermore, if an upward force is applied to the outlet grill 20 due to the impact of the outdoor unit 1 being dropped during transportation of the outdoor unit 1, the positioning member 41 is inserted into the positioning opening 40, so the vertical position of the outlet grill 20 will not shift, and the engagement between the locking claws 22 of the locking member 21 and the flange portion 31 can prevent the outlet grill 20 from coming off.

[0035] [4-3. Effects, etc.] As described above, in the outdoor unit 1 of this embodiment, the housing 10 is provided with a positioning opening 40, the outlet grill 20 is provided with a positioning member 41 that is inserted into the positioning opening 40, and the underside of the positioning member 41 is provided with a second locking claw 43 that engages with the lower part of the positioning opening 40. As a result, the locking claws 22 of the locking member 21 are locked in the locking openings 30, thereby fixing the outlet grill 20 to the front panel 16 of the housing 10. Furthermore, when an upward force is applied to the outlet grill 20 due to an impact such as when the outdoor unit 1 is dropped, the position of the outlet grill 20 in the vertical direction will not shift because the positioning member 41 is inserted into the positioning opening 40, and the engagement between the locking claws 22 of the locking member 21 and the flange portion 31 can prevent the outlet grill 20 from coming off. In addition, the positioning member 41 is also provided with the second locking claws 43, so that the outlet grill 20 can be held more firmly.

[0036] (Modification of the fourth embodiment) In the fourth embodiment, the positioning member 41 is provided adjacent to the upper portion of the positioning opening 40, but the present disclosure is not limited to this. FIG. 11 is a perspective view showing a modified example of the fixed state between the outlet grill 20 and the front panel 16 in the fourth embodiment. As shown in FIG. 11, a positioning member 41 may be provided adjacent to the lower portion of the positioning opening 40 . In this case, the locking claw 22 of the locking member 21 is caught in the locking opening 30, and the second locking claw 43 of the positioning member 41 is caught in the positioning opening 40, respectively. However, since each of the locking claws 22, 43 is formed tapered, when inserting the locking member 21 and the positioning member 41, the locking member 21 and the positioning member 41 are bent by the tapered surfaces of the locking claws 22, 43, making the insertion operation easy. In this case as well, the same functions and effects as those in the fourth embodiment can be obtained.

[0037] (Embodiment 5) Next, a fifth embodiment will be described. In the following, the same parts as those in the above-mentioned embodiments will be denoted by the same reference numerals. [5-1. Configuration] FIG. 12 is a cross-sectional view showing a fixed state between outlet grill 20 and front panel 16 in the fifth embodiment. As shown in FIG. 12, in this embodiment, the locking opening and the positioning opening are formed as one continuous opening 50. As shown in FIG. The configurations of the locking member 21 and the positioning member 41 are the same as those in the third embodiment.

[0038] FIG. 13 is a perspective view showing a fixed state between the outlet grill 20 and the front panel 16 according to a modification of the fifth embodiment. As shown in FIG. 13, a positioning member 41 may be provided with a second locking claw 43, similar to the fourth embodiment.

[0039] [5-2. Actions and Effects] In the present embodiment, similarly to the third and fourth embodiments, the locking member 21 and the positioning member 41 of the outlet grill 20 are inserted into the opening in the front panel 16, thereby fixing the outlet grill 20 to the front panel 16 of the housing 10. Furthermore, if an upward force is applied to the outlet grill 20 due to an impact when the outdoor unit 1 is dropped during transportation, the positioning member 41 is inserted into the opening 50, so that the position of the outlet grill 20 in the vertical direction is not shifted, and the engagement between the locking claws 22 of the locking member 21 and the flange portion 31 can prevent the outlet grill 20 from coming off.

[0040] [5-3. Effects, etc.] As described above, in the outdoor unit 1 in this embodiment, the locking opening and the positioning opening are formed as a single opening 50. As a result, by inserting the locking members 21 and positioning members 41 of the outlet grill 20 into the opening 50, the outlet grill 20 can be fixed to the front panel 16 of the housing 10. Furthermore, if an upward force is applied to the outlet grill 20 due to an impact when the outdoor unit 1 is dropped during transportation of the outdoor unit 1, the position of the outlet grill 20 will not shift in the up-down direction because the positioning members 41 are inserted into the opening 50, and the engagement between the locking claws 22 of the locking members 21 and the flange portion 31 can prevent the outlet grill 20 from coming off.

[0041] (Other embodiments) As described above, the first to fifth embodiments have been described as examples of the technology disclosed in this application.
