Specific embodiments

[0034] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0035] The outdoor unit of an air conditioner provided by an embodiment of the present utility model, as Figures 2 to 4 、 Figure 6 shown, includes: a chassis 100; and a mounting structure for a water pump assembly. The mounting structure of the water pump assembly includes a mounting frame 200 and a water pump assembly 960. The mounting frame 200 is vertically fixed on the chassis 100 in the left-right direction, and the water pump assembly 960 is located on the front side of the mounting frame 200. Among them, one of the mounting frame 200 and the water pump assembly 960 is provided with a guide rail 961 and a first connection part, and the other is provided with a guide rail groove 208 and a second connection part. The guide rail 961 is inserted into the guide rail groove 208, and the first connection part and the second connection part are fixedly connected.

[0036] The guide rail 961 is inserted into the guide rail groove 208, which defines the relative positions of the mounting frame 200 and the water pump assembly 960, facilitating the quick alignment of the first connection part and the second connection part for fixed connection. This solution can effectively improve the assembly efficiency of the mounting frame 200 and the water pump assembly 960.

[0037] In some embodiments, as Figures 3 to 6As shown, the guide rail groove 208 includes a first slot 2081 and a second slot 2082 with opposite slot openings. The first ends (such as the right ends) of the first slot 2081 and the second slot 2082 are both through. A pair of opposite sides of the guide rail 961 (the opposite sides of the guide rail 961 in the up and down directions) are inserted into the space between the first slot 2081 and the second slot 2082 from the first ends of the first slot 2081 and the second slot 2082 in a one-to-one correspondence and towards the left.

[0038] Among them, as Figures 3 to 6 shown, the first slot 2081 and the second slot 2082 are located on the front side of the mounting bracket 200. It is possible that two bending plates 2083 bent forward are provided on the front side of the mounting bracket 200. The two bending plates 2083 are arranged at an interval and symmetrically in the up and down directions to form the first slot 2081 and the second slot 2082. The bending angle b of the bending plate 2083 is set to 100 degrees to 120 degrees, which is more conducive to the upper edge and the lower edge of the guide rail 961 being inserted into the first slot 2081 and the second slot 2082 from the first ends of the first slot 2081 and the second slot 2082 in a one-to-one correspondence.

[0039] Furthermore, as Figure 6 shown, one of the first ends of the first slot 2081 and the first ends of the second slot 2082 protrudes relative to the other in the depth direction away from the guide rail groove 208. In this way, when inserting the guide rail 961, the guide rail 961 first abuts against the inside of the protruding part. This solution is more conducive to the quick insertion of the guide rail 961 into the first slot 2081 and the second slot 2082.

[0040] It is possible that, as Figure 6 shown, the first slot 2081 is located above the second slot 2082, and the right end of the second slot 2082 protrudes towards the right relative to the right end of the first slot 2081. In this way, the lower edge of the left end of the guide rail 961 first abuts downwards against the inside of the right end of the second slot 2082 (at this time, the upper edge of the left end of the guide rail 961 does not enter the first slot 2081), and then the guide rail 961 is inserted towards the left. This solution is conducive to the quick leftward insertion of the guide rail 961 into the first slot 2081 and the second slot 2082. Or it is possible that the first slot 2081 is located above the second slot 2082, and the right end of the first slot 2081 protrudes towards the right relative to the right end of the second slot 2082. In this way, the upper edge of the left end of the guide rail 961 first abuts upwards against the inside of the right end of the first slot 2081 (at this time, the lower edge of the left end of the guide rail 961 does not enter the second slot 2082), and then the guide rail 961 is inserted towards the left. This solution is conducive to the quick leftward insertion of the guide rail 961 into the first slot 2081 and the second slot 2082. The above can all achieve the purpose of this application, and its gist does not deviate from the design concept of the present utility model, so it will not be elaborated here and all should fall within the protection scope of this application.

[0041] Further, as Figure 5 shown, after the guide rail 961 is fully inserted in place, the fitting clearances a and c between the groove wall of the first slot 2081 and the guide rail 961 are both set to 1.5 mm to 5 mm, which is conducive to ensuring that the guide rail 961 slides more smoothly along the first slot 2081 and the second slot 2082.

[0042] Still further, as Figure 3 and Figure 4 shown, the guide rail 961 is provided with a limiting portion 962, and the groove wall of the guide rail groove 208 is provided with a mating portion 2084. The limiting portion 962 cooperates with the mating portion 2084 to be set to limit the insertion depth of the guide rail 961 in the guide rail groove 208, so as to ensure that when the guide rail 961 is fully inserted into the first slot 2081 and the second slot 2082, the first connecting portion and the second connecting portion are exactly aligned. It can be that the right end of the guide rail 961 is provided with a stop edge protruding backward, and the mating portion 2084 is the right end of the mounting frame 200. After the guide rail 961 is fully inserted in place, the stop edge abuts against the right end of the mounting frame 200 to the left to achieve limiting.

[0043] In some examples, as Figure 3 、 Figures 7 to 9 shown, the guide rail 961 is provided at the rear side of the water pump assembly 960 and includes a frame plate 963 and a first mounting plate 964 with a flange. The guide rail groove 208 is located at the front side of the mounting frame 200. The frame plate 963 is inserted into the guide rail groove 208. An avoidance hole is provided on the side surface of the frame plate 963. The first mounting plate 964 is provided at the avoidance hole. The flange is held on the outer end surface of the avoidance hole on the side of the bottom wall of the frame plate 963 facing away from the guide rail groove 208. The first connecting portion is located on the first mounting plate 964, and the second connecting portion is located on the bottom wall of the guide rail groove 208. The bottom wall of the guide rail groove 208 faces the notch of the guide rail groove 208. It can be that the first connecting portion is a first screw hole, and the second connecting portion is a second screw hole. A screw passes through the first screw hole and the avoidance hole and is screwed into the second screw hole to fix the mounting frame 200, the frame plate 963 and the first mounting plate 964 together. At this time, the frame plate 963 is clamped between the first mounting plate 964 and the mounting frame 200. Preferably, the limiting portion 962 is located at the right end of the frame plate 963, and the frame plate 963 is welded to the first mounting plate 964.

[0044] Among them, the avoidance holes and the first mounting plates 964 include two groups arranged at upper and lower intervals. The upper and lower portions of each first mounting plate 964 both have flanges. The flanges on the upper portion and the lower portion of each first mounting plate 964 are held on the upper and lower portions of the outer end surface of the corresponding avoidance hole on the side of the bottom wall of the guide rail groove 208 facing away from it, so as to ensure that the first mounting plate 964 stably presses the frame plate 963 on the mounting frame 200.

[0045] Furthermore, as Figure 3 、Figure 5 , Figures 7 to 9 As shown in Figures 7 to 9 , the water pump assembly 960 includes: a guide rail 961; and a water pump main body 965. The water pump main body 965 is located on the front side of the guide rail groove 208 and is provided with a flange 966. The flange 966 is fixedly connected to the shelf plate 963 of the guide rail 961, so that the water pump main body 965 and the shelf plate 963 are fixedly connected together.

[0046] Furthermore, as shown in Figure 7 , Figure 8 and Figure 10 shown, the water pump assembly 960 further includes: a second mounting bracket 967. The second mounting bracket 967 is located on the side of the flange 966 facing away from the shelf plate 963 and is fixedly provided with a nut. A bolt passes through the shelf plate 963 and the flange 966 in sequence and is screwed onto the nut, so that the second mounting bracket 967, the water pump main body 965 and the shelf plate 963 are fixedly connected together by the bolt. The nut is fixedly provided on the second mounting bracket 967, and the nut will not rotate with the bolt when the bolt is screwed. It can be that the nut is welded or riveted to the second mounting bracket 967.

[0047] Still further, as shown in Figure 7 , Figure 8 and Figure 10 shown, the second mounting bracket 967 is U-shaped and is provided with an anti-rotation portion. The nut is fixedly provided on the two vertical sides of the second mounting bracket 967. A total of two second mounting plates are provided at the left end and the right end of the side of the water pump main body 965 facing the guide rail 961. The two vertical sides of the second mounting bracket 967 are respectively placed on the side of the two second mounting plates facing away from the shelf plate 963. The flange 966 includes two second mounting plates. In this solution, both the left side and the right side of the water pump main body 965 are fixedly connected to the shelf plate 963. After the water pump main body 965 is fixed on the shelf plate 963, the water pump main body 965 is less likely to loosen. Among them, the anti-rotation portion is matched with the water pump main body 965 and is set to prevent the water pump main body 965 and the second mounting bracket 967 from rotating relatively. In this way, during the process of screwing the bolt, the water pump main body 965 and the second mounting bracket 967 will not rotate relatively and be misaligned.

[0048] It can be that, as shown in Figure 7 , Figure 8 and Figure 10 shown, the horizontal side of the second mounting bracket 967 is provided with an anti-rotation convex block 968 protruding forward, and the ends of the two vertical sides of the second mounting bracket 967 are provided with anti-rotation folded edges 969 bending forward. The side surface of the water pump main body 965 is provided with a recessed portion. The anti-rotation convex block 968 is matched with the recessed portion, and the water pump main body 965 is located between the two anti-rotation folded edges 969 to limit the two anti-rotation folded edges 969, so as to prevent the water pump main body 965 and the second mounting bracket 967 from rotating relatively.

[0049] It can be that the anti-rotation convex block 968 is set as a sponge or a rubber pad or a silica gel pad for shock absorption, etc. As shown inFigure 8 and Figure 9 As shown in Figure 9 , a shock pad 980 for shock absorption is provided between the second mounting plate and the frame plate 963. There are two shock pads 980, and each shock pad 980 is made of a rubber pad or a silica gel pad, etc.

[0050] In some embodiments, as Figure 9 , Figures 11 to 14 shown, the side of the frame plate 963 is provided with a socket hole 9631, the side of the shock pad 980 is provided with a socket post 981, and the side of the socket post 981 is provided with a slot 982. The shock pad 980 is placed on the side of the frame plate 963, the socket post 981 is inserted into the socket hole 9631, and the hole wall of the socket hole 9631 is snapped into the slot 982, so that the shock pad 980 and the frame plate 963 are assembled together. This solution is not only simple to operate and time-consuming, but also the shock pad 980 is not easy to fall off the frame plate 963.

[0051] Among them, as Figures 12 to 14 shown, the socket post 981 includes: a first post segment 983; and a second post segment 984. The second post segment 984 is connected to the shock pad 980 through the first post segment 983. The second post segment 984, the first post segment 983 and the shock pad 980 enclose the slot 982, so that after the second mounting plate, the shock pad 980 and the frame plate 963 are assembled together, the shock pad 980 is completely attached to the frame plate 963.

[0052] Furthermore, as Figures 12 to 14 shown, the socket post 981 further includes: a third post segment, which is located on the side of the second post segment 984 facing away from the first post segment 983 and is connected to the second post segment 984, and a gripping groove 988 is provided on the side of the third post segment. After the third post segment passes through the socket hole 9631, the gripping groove 988 is pulled to make the second post segment 984 pass through the socket hole 9631, so that the hole wall of the socket hole 9631 is snapped into the slot 982.

[0053] Further, as Figures 12 to 14 shown, the third post segment includes: a first sub-post segment 985, which is located on the side of the second post segment 984 facing away from the first post segment 983 and is connected to the second post segment 984, and the diameter of the first sub-post segment 985 gradually decreases from the end adjacent to the second post segment 984 to the end away from the second post segment 984; and a second sub-post segment 986, which is located on the side of the first sub-post segment 985 facing away from the second post segment 984 and is connected to the first sub-post segment 985, and the diameter of the second sub-post segment 986 gradually increases from the end adjacent to the first sub-post segment 985 to the end away from the first sub-post segment 985. The first sub-post segment 985 and the second sub-post segment 986 enclose the gripping groove 988.

[0054] Still further, as Figures 12 to 14As shown, the insertion post 981 further includes: a fourth post segment 987, which is located on the side of the second sub-post segment 986 facing away from the first sub-post segment 985 and is connected to the second sub-post segment 986. In this way, when the third post segment is being pulled, it is not easy for a finger to slip out of the holding groove 988.

[0055] In some embodiments, as Figure 14 shown, the sum of the axial lengths of the second post segment 984, the third post segment, and the fourth post segment 987 is h, where h≥10 mm. In this way, it is not easy for the hole wall of the insertion hole 9631 to come out of the card slot 982.

[0056] In some embodiments, as Figure 14 shown, the sides of the first post segment 983, the second post segment 984, and the fourth post segment 987 are cylindrical surfaces, and the side of the first sub-post segment 985 is a conical surface. Among them, the minimum width of the insertion hole 9631 is A (if the insertion hole 9631 is a circular hole, the diameter of the insertion hole 9631 is A; if the insertion hole 9631 is a waist-shaped hole or an elliptical hole, etc., the minimum width of the insertion hole 9631 is A), the diameter of the first post segment 983 is a, where a≤A - 0.4 mm, the diameter of the second post segment 984 is b, where A + 1.5 mm≤b≤A + 2 mm, and b - A≥A - a. The gap between the side wall of the card slot 982 and the shelf plate is i, where 0.2 mm≤i≤1 mm. The central angle of the side of the first sub-post segment 985 is g, where g≤150 degrees. The diameter of the end of the first sub-post segment 985 adjacent to the second post segment 984 is b, and the diameter of the end of the first sub-post segment 985 far from the second post segment 984 is c, where c≤b - 1 mm. The axial length of the second sub-post segment 986 is f, where f≥1 mm. The diameter of the end of the second sub-post segment 986 far from the first sub-post segment 985 is d, where d≤A - 0.5 mm. The diameter of the fourth post segment 987 is also d, and the axial length of the fourth post segment 987 is e, where e≥3 mm. This solution can enable the insertion post 981 to be quickly inserted in place in the insertion hole 9631.

[0057] It can be, as Figures 11 to 13 shown, each shock pad 980 is provided with a plurality of insertion posts 981, and the plurality of insertion posts 981 are inserted into the insertion holes 9631 one by one. The plurality can be two or three or four, etc. In this way, after the shock pad 980 is installed on the shelf plate 963, the shock pad 980 will not rotate around the insertion post 981 on the shelf plate 963.

[0058] It can be, as Figure 2 shown, the control box of the water pump main body 965 is located on the front side of the water pump main body 965, and the lid of the control box faces forward. In this way, it is convenient to wire the control box on the front side of the air conditioner outdoor unit and also convenient to repair the control box.

[0059] It can be, as Figure 3and Figure 6 As shown in Figure 6 , a third mounting plate 209 is fixed to the front side of the mounting bracket 200, and the third mounting plate 209 defines a guide rail groove 208.

[0060] In some embodiments, as Figure 1 shown, the outdoor unit of the air conditioner further includes a side rear plate 800 (i.e., the right rear plate), a side front plate 910 (i.e., the right front plate), an electronic control cover plate 920, a maintenance plate 930, and a fixing plate 940. The electronic control cover plate 920 is erected in the front-rear direction at the rear side of the side front plate 910 and above the side plate of the side rear plate 800. The maintenance plate 930 is located below the side plates of the side front plate 910 and the side rear plate 800. A notch is provided at the lower part of the maintenance plate 930, and the fixing plate 940 is located at the notch. The maintenance plate 930 and the fixing plate 940 together enclose a through hole for passing through the water inlet pipe and the water outlet pipe of the outdoor unit of the air conditioner. The side plates of the side front plate 910, the side plates of the side rear plate 800, the electronic control cover plate 920, the maintenance plate 930, and the fixing plate 940 together construct the right side wall of the outdoor unit of the air conditioner.

[0061] The air conditioner provided by the embodiment of the present invention (not shown in the figure) includes the outdoor unit of the air conditioner described in any of the above embodiments.

[0062] This air conditioner has all the advantages of the outdoor unit of the air conditioner provided in any of the above embodiments, which will not be elaborated here.

[0063] Among them, the air conditioner is a water-to-water and water-to-earth air conditioner.

[0064] In summary, for the installation structure of the water pump assembly provided by the embodiment of the present invention, the guide rail is inserted into the guide rail groove, which defines the relative positions of the mounting bracket and the water pump assembly, facilitating the quick alignment of the first connecting portion and the second connecting portion for fixation. This solution can effectively improve the assembly efficiency of the mounting bracket and the water pump assembly.
