Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioning outdoor unit. Background Art

[0002] The fan cover is one of the important parts of the air conditioner outdoor unit. It can not only protect the fan blades and prevent indoor debris from accidentally entering and damaging the fan or causing accidents, but also make the gas sucked in by the fan more concentrated, focus the blown air, improve the heat dissipation effect, and make the cooling and heating effects better.

[0003] In some air-conditioning outdoor units, a hook and an insertion port are usually used to cooperate with each other to achieve a detachable connection between the fan cover and the front panel. For example, a hook is set on the side of the fan cover facing the front panel, and an insertion port is set on the front panel. The hook is inserted into the insertion port and rotated clockwise or counterclockwise by a certain angle to make the hook and the outer edge of the insertion port cooperate with each other, so that the fan cover is connected to the front panel. However, since the front panel is usually a sheet metal part and the fan cover is usually a plastic part, burrs are easily generated on the edge of the insertion port. During the cooperation between the hook and the outer edge of the insertion port, the burrs may scratch the hook; and in the prior art, the hook and the insertion port are usually arranged to contact each other along the rotation direction of the hook to ensure that the hook is rotated in place. During the cooperation between the hook and the inner edge of the insertion port, the hook is easily subjected to a large force, resulting in the hook being broken and damaged.

[0004] Therefore, the fan cover in the prior art still cannot well meet the requirements of the air conditioner outdoor unit. Utility Model Content

[0074] In this embodiment, the first side plate 130 is located on the left side of the housing 100 , the second side plate 160 is located on the right side of the housing 100 , and the housing air outlet 102 is disposed on the second side plate 160 .

[0075] It should be noted that the casing 100 may include a rear side panel or may not include a rear side panel. In this embodiment, the casing 100 does not include a rear side panel to increase the air intake volume of the air conditioner outdoor unit.

[0076] like Figure 4 As shown, the housing 100 includes a partition 150, which is located inside the housing 100. The partition 150 divides the inside of the housing 100 into a first cavity and a second cavity. The housing air outlet 102 and the housing air inlet 101 are respectively connected to the first cavity.

[0077] like Figure 4 As shown, the air conditioner outdoor unit includes a heat exchanger 400, which is disposed in the first cavity and close to the air inlet 101 of the casing. The heat exchanger 400 is used to exchange heat for the air passing through it.

[0078] In some embodiments, the heat exchanger 400 extends from the left side of the casing 100 through the rear side of the casing 100 to the right side of the casing 100, so as to maximize the heat exchange area of ​​the heat exchanger 400 while keeping the internal space of the casing 100 unchanged.

[0079] like Figure 3 and Figure 4 As shown, the air conditioner outdoor unit includes a fan 300 , which is disposed in the first cavity. The fan 300 is located on the leeward side of the heat exchanger 400 , and the fan 300 is disposed close to the air outlet 102 of the casing.

[0080] The fan 300 operates to introduce air outside the casing 100 into the first cavity through the casing air inlet 101 , and is output to the outside of the casing 100 through the casing air outlet 102 after heat exchange in the heat exchanger 400 .

[0081] In this embodiment, the fan 300 is an axial flow fan 300 .

[0082] like Fig. 9 and Fig.11 As shown, the air conditioner outdoor unit includes an air guide ring 121, which is arranged at the air outlet 102 of the casing to guide the air flow; the air guide ring 121 is connected to the front panel 120, and the side of the air guide ring 121 away from the front panel 120 is located in the first cavity and is arranged toward the fan 300.

[0083] like Figure 4 As shown, the air-conditioning outdoor unit includes a compressor 500, which is disposed in the second chamber and is used to drive the refrigerant to flow.

[0084] like Figure 1 and Figure 2 As shown, the air conditioner outdoor unit includes a fan cover 200, which is located at the air outlet 102 of the casing and is installed on the front panel 120; on the one hand, the fan cover 200 can protect the fan 300 to prevent debris from entering the casing 100 through the air outlet 102 of the casing and contacting the fan 300, thereby affecting the normal operation of the fan 300; on the other hand, it can make the gas inhaled by the fan more concentrated, thereby increasing the speed and pressure of the gas, and ultimately increasing the wind force output by the fan. In other words, the fan cover 200 can focus the blown air, improve the heat dissipation effect, and achieve better cooling and heating effects.

[0085] like Figure 6 and Figure 7 As shown, the fan cover 200 includes a grille, which defines a plurality of vents 201 , which are connected to the first cavity, and the air in the first cavity is output to the outside of the casing 100 through the vents 201 from the casing air outlet 102 .

[0086] like Figure 6 and Figure 7 As shown, the fan cover 200 includes a frame 240 , and the frame 240 is used to define the shape of the fan cover 200 . The grille is disposed in the frame 240 and connected to the frame 240 .

[0087] In this embodiment, the frame 240 is annular, and correspondingly, the fan cover 200 is circular.

[0088] like Figure 6 and Figure 7 As shown, the grille includes a middle piece 210, which is located in the middle portion of the grille. The middle piece 210 is generally circular.

[0089] like Figure 6 and Figure 7 As shown, the grille includes circumferential ribs 230 , which are arranged along the circumference of the middle piece 210 . The circumferential ribs 230 are arranged in plurality, and the plurality of circumferential ribs 230 are arranged in the radial direction of the middle piece 210 .

[0090] It should be noted that, in this embodiment, the intermediate piece 210 and the plurality of circumferential ribs 230 are arranged concentrically.

[0091] like Figure 6 and Figure 7 As shown, the grille includes radial ribs 220, which are arranged along the radial direction of the middle piece 210. The radial ribs 220 are arranged in plurality, one end of the radial rib 220 in the length direction is arranged toward the middle piece 210, and the other end of the radial rib 220 in the length direction is arranged in the direction away from the middle piece 210; the radial ribs 220 and the circumferential ribs 230 are cross-connected with each other to jointly define the ventilation opening 201.

[0092] like Figure 7 As shown, the fan cover 200 includes a connecting piece 260, which is located on the side of the fan cover 200 facing the inside of the casing 100, and is arranged at the outer edge of the fan cover 200. The connecting piece 260 is interconnected with the front panel 120 so that the fan cover 200 is installed on the front panel 120.

[0093] like Fig.12 As shown, the front panel 120 includes an insertion portion 124, which is located at the outer edge of the casing air outlet 102, and the insertion portion 124 is connected to the first cavity; the connecting piece 260 extends from the insertion portion 124 into the interior of the casing 100 and cooperates with the outer edge of the insertion portion 124 or the front panel 120 to connect the fan cover 200 and the front panel 120 to each other.

[0094] The inserting portion 124 is disposed along the circumference of the fan cover 200 to guide the connecting member 260 to rotate along the inserting portion 124 relative to the front panel 120 .

[0095] The connecting member 260 and the fan cover 200 define an accommodating portion 263 on one side facing the interior of the casing 100. After the connecting member 260 is extended into the first cavity through the insertion portion 124, the connecting member 260 is rotated at a certain angle relative to the front panel 120 so that at least part of the outer edge of the insertion portion 124 is disposed in the accommodating portion 263, thereby connecting the fan cover 200 and the front panel 120 to each other.

[0096] It should be noted that the setting direction of the insertion portion 124 is set corresponding to the rotation direction of the connecting member 260.

[0097] The dimension of the connecting member 260 along its rotation direction is smaller than or equal to the dimension of the inserting portion 124 along the rotation direction of the connecting member 260 to avoid the edge of the inserting portion 124 interfering with the connecting member 260 and ensure that the connecting member 260 can extend from the inserting portion 124 into the interior of the housing 100 .

[0098] A plurality of connecting members 260 are provided, and the plurality of connecting members 260 are arranged along the outer edge of the fan cover 200 to increase the reliability of the connection between the fan cover 200 and the front panel 120 .

[0099] In this embodiment, eight connecting members 260 are provided, and the eight connecting members 260 are evenly distributed along the outer edge of the fan cover 200 .

[0100] like Figure 7 As shown, the connecting member 260 is connected to the frame 240 .

[0101] like Figure 8 As shown, the connecting member 260 includes a connecting portion 264 , one end of the connecting portion 264 in the length direction is connected to the side of the fan cover 200 facing the inside of the casing 100 , and the other end of the connecting portion 264 in the length direction can be extended into the casing 100 through the insertion portion 124 .

[0102] like Figure 8 As shown, the connecting member 260 includes a restraining portion 261, and the length direction of the restraining portion 261 is set corresponding to the rotation direction of the connecting member 260; one end of the restraining portion 261 in the length direction is connected to the connecting portion 264, and the other end of the restraining portion 261 in the length direction is set forward toward the rotation direction of the connecting portion 264, and the restraining portion 261 and the side of the fan cover 200 facing the inside of the casing 100 together define a receiving portion 263.

[0103] It should be noted that the length direction of the restraining portion 261 intersects with the length direction of the connecting member 260 .

[0104] In actual applications, the front panel 120 is usually a sheet metal part, and the insertion part 124 is usually an insertion port. The insertion part 124 is usually produced by stamping or cutting. Burrs are easily generated on the edge of the insertion part 124. If the connecting part 260 contacts the edge of the insertion part 124, the burrs are easy to damage the connecting part 260, thereby reducing the service life of the fan cover 200.

[0105] Based on this, Figure 8 As shown, the connector 260 is provided with a mating portion 262 , which is disposed in the accommodating portion 263 and protrudes from the accommodating portion 263 toward the side of the fan cover 200 , and the mating portion 262 contacts the side of the front panel 120 toward the inside of the casing 100 .

[0106] By arranging the protruding accommodation portion 263 of the mating portion 262 toward the side of the fan cover 200, the distance between the constraint portion 261 and the front panel 120 toward the inside of the casing 100 is increased, thereby avoiding contact between the burrs on the edges of the constraint portion 261 and the insertion portion 124, thereby reducing damage to the constraint portion 261 caused by the burrs.

[0107] The mating portion 262 is disposed near the front end of the connecting member 260 along its rotation direction. After the connecting member 260 extends from the insertion portion 124 into the first cavity and rotates a certain angle relative to the front panel 120 , the mating portion 262 and the side of the front panel 120 facing the inside of the housing 100 contact each other.

[0108] like Fig.10 and Fig.12 As shown, a protrusion 123 is provided on the side of the front panel 120 facing the inside of the casing 100, and the protrusion 123 protrudes the side of the front panel 120 facing the inside of the casing 100; the protrusion 123 is arranged close to the insertion portion 124, and the protrusion 123 is located in front of the insertion portion 124 along the rotation direction of the connecting member 260, and the matching portion 262 and the protrusion 123 are in contact with each other, so that the protrusion 123 exerts a constraint on the constraint portion 261, which can not only realize the mutual connection between the fan cover 200 and the front panel 120, but also can perform circumferential positioning of the fan cover 200 and locate the installation position of the fan cover 200.

[0109] After the connecting member 260 extends from the insertion portion 124 into the first cavity and rotates along the insertion portion 124 relative to the front panel 120 at a certain angle, the matching portion 262 and the protruding portion 123 contact each other.

[0110] The matching portion 262 is interference-fitted with the protruding portion 123 to increase the firmness of the connection between the fan cover 200 and the front panel 120 and prevent the fan cover 200 from shaking relative to the front panel 120 .

[0111] In this embodiment, the interference between the restraining portion 261 and the protruding portion 123 is 0.4 mm-0.8 mm, so as to ensure the connection strength between the fan cover 200 and the front panel 120 .

[0112] The thickness of the front panel 120 is H, and there is a gap along the first direction between the fitting portion 262 and the side of the fan cover 200 facing the inside of the casing 100. When the outer edge of the insertion portion 124 is arranged in the accommodating portion 263, the first direction is arranged corresponding to the thickness direction of the front panel 120; the size of the gap in the first direction is L, and L and H satisfy the relationship: L≥H, so as to prevent the connecting member 260 from extending into the inside of the casing 100 and the fitting portion 262 and the side of the front panel 120 facing the inside of the casing 100 from contacting each other during the rotation of the connecting member 260.

[0113] If L<H, the matching portion 262 and the front panel 120 interfere with each other, resulting in the front panel 120 being unable to be disposed in the accommodating portion 263, or when the front panel 120 is disposed in the accommodating portion 263, the matching portion 262 and the front panel 120 squeeze each other, requiring greater force to make the matching portion 262 and the protrusion 123 contact each other.

[0114] When the constraint portion 261 and the protrusion 123 are in contact with each other, the fan cover 200 is installed in place and the connecting piece 260 is stopped from rotating to avoid the connecting portion 264 and the edge of the insertion portion 124 from contacting each other. This can not only prevent the burrs on the edge of the insertion portion 124 from damaging the connecting portion 264, but also prevent the connecting portion 264 and the edge of the insertion portion 124 from colliding with each other when the connecting piece 260 is rotated, thereby damaging the connecting portion 264.

[0115] like Figure 8 As shown, a contact portion 270 is provided on the side of the fan cover 200 facing the interior of the casing 100, and the contact portion 270 contacts the outer edge of the casing air outlet 102 on the side facing away from the interior of the casing 100 to reduce the contact area between the fan cover 200 and the front panel 120, thereby avoiding mutual friction between the fan cover 200 and the front panel 120 when the connecting piece 260 rotates and damaging the fan cover 200 or the front panel 120.

[0116] There are multiple contact portions 270 , and the multiple contact portions 270 are arranged along the outer edge of the housing air outlet 102 , so that the fan cover 200 and the front panel 120 are subjected to uniform force.

[0117] like Figure 6 As shown, the fan cover 200 is provided with a first fixing portion 250 , and the first fixing portion 250 is fixedly connected to the front panel 120 by fasteners such as bolts or screws.

[0118] like Fig.12 and Fig.14As shown, the front panel 120 is provided with a second fixing portion 122, the second fixing portion 122, the insertion portion 124 and the protrusion 123 are arranged along the rotation direction of the connecting member 260, the second fixing portion 122 is arranged corresponding to the first fixing portion 250, and the first fixing portion 250 and the second fixing portion 122 are connected with the same fastener to fix the fan cover 200 to the front panel 120.

[0119] The second fixing portion 122 is disposed at the outer edge of the housing air outlet 102 and is disposed close to the bottom of the housing 100;

[0120] The first fixing portion 250 is disposed on the frame 240 . When the first fixing portion 250 and the second fixing portion 122 are connected to each other through the same fastener, the first fixing portion 250 is disposed close to the bottom of the housing 100 .

[0121] The first fixing portion 250 is provided with a first connecting hole, the second fixing portion 122 is provided with a second connecting hole, and the same fastener is provided in both the first connecting hole and the second connecting hole to connect the first fixing portion 250 and the second fixing portion 122 to each other.

[0122] It should be noted that when the fan cover 200 is installed, the first fixing portion 250 is rotated relative to the second fixing portion 122 so that the first fixing portion 250 and the second fixing portion 122 are disposed correspondingly.

[0123] It should also be noted that when the matching portion 262 and the protruding portion 123 are in contact with each other, the first fixing portion 250 and the second fixing portion 122 are arranged correspondingly.

[0124] The fan cover 200 and the front panel 120 are initially fixed by the matching portion 262 and the protruding portion 123, and the first fixing portion 250 and the second fixing portion 122 perform secondary fixing on the fan cover 200 and the front panel 120. Since the initial fixing effect of the fan cover 200 and the front panel 120 is good, the second fixing portion 122 is set to not only meet the connection firmness requirement of the fan cover 200 and the front panel 120, but also save the number of fasteners.

[0125] In actual applications, the connecting member 260 can be designed to rotate clockwise relative to the front panel 120 so that the fan cover 200 and the front panel 120 are interconnected. The connecting member 260 can also be designed to rotate counterclockwise relative to the front panel 120 so that the fan cover 200 and the front panel 120 are interconnected. However, it should be noted that the structure of the connecting member 260 designed to rotate clockwise is different from that of the connecting member 260 designed to rotate counterclockwise. Usually, the structure of the connecting member 260 designed to rotate clockwise is opposite to that of the connecting member 260 designed to rotate counterclockwise. This is common knowledge in the field and will not be repeated here.

[0126] The installation steps of the fan cover 200 in the above-mentioned air-conditioning outdoor unit are as follows: the connecting piece 260 is extended into the interior of the casing 100 from the insertion portion 124 and rotated along the insertion portion 124 relative to the front panel 120 at a certain angle, so that the matching portion 262 and the protrusion 123 contact each other, so as to preliminarily fix the fan cover 200 and the front panel 120; the first fixing portion 250 and the second fixing portion 122 are arranged correspondingly, and a fastener is arranged on the first fixing portion 250 and the second fixing portion 122 at the same time, so that the fan cover 200 and the front panel 120 are fixedly connected by the fastener, so as to perform secondary fixation on the fan cover 200 and the front panel 120.

[0127] Since the mating portion 262 and the protruding portion 123 are interference fit, when the mating portion 262 and the protruding portion 123 contact each other, although the fan cover 200 and the front panel 120 are connected to each other, the connection firmness between the fan cover 200 and the front panel 120 is low at this time. Therefore, fasteners are required to perform secondary fixation on the fan cover 200 and the front panel 120.

[0128] The above-mentioned air-conditioning outdoor unit is configured by providing a connecting piece 260 on the fan cover 200 and an inserting portion 124 on the front panel 120, and utilizing the mutual cooperation between the connecting piece 260 and the inserting portion 124 to preliminarily connect the fan cover 200 and the front panel 120, and then only using one fastener to achieve secondary fixation of the fan cover 200 and the front panel 120, which can not only achieve a firm connection between the fan cover 200 and the front panel 120, but also save the number of fasteners, improve the assembly efficiency of the fan cover 200, and reduce the assembly cost of the fan cover 200.

[0129] The above-mentioned air-conditioning outdoor unit is configured with a protrusion 123 on the side of the front panel 120 facing the inside of the casing 100, and the protrusion 123 is used to contact the connecting piece 260 so as to connect the fan cover 200 with the front panel 120; the connecting piece 260 is extended into the casing 100 from the insertion portion 124 and is rotated along the insertion portion 124 relative to the front panel 120 by a certain angle so as to contact the protrusion 123, so as to locate the installation position of the fan cover 200, avoid contact between the edge of the connecting portion 264 and the edge of the inserting portion 124, and thus avoid damage to the connecting portion 264 due to the force of the edge of the inserting portion 124.

[0130] The above-mentioned air-conditioning outdoor unit is provided with a mating portion 262 so that the mating portion 262 protrudes the accommodating portion 263 toward the side of the fan cover 200, so that there is a gap between the side of the accommodating portion 263 toward the fan cover 200 and the side of the front panel 120 toward the inside of the casing 100, thereby avoiding the edge of the constraint and the insertion portion 124 from contacting each other, and further avoiding the burrs on the edge of the insertion portion 124 from damaging the side of the accommodating portion 263 toward the fan cover 200.

[0131] The fan cover 200 in the above-mentioned air-conditioning outdoor unit has good protection effect and a long service life.
