[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] First embodiment

[0045] See also Figures 1 to 3 The present embodiment provides an electric control box installation assembly 100, which avoids obstruction to the air duct and increases the air volume of the air duct. At the same time, the installation is quick and convenient, the operation is simple and labor-saving, the assembly efficiency is high, the wiring is convenient, the lines are neat, and it is not easy to make mistakes, and different lines can avoid mutual influence.

[0046] The electric control box installation assembly 100 provided in this embodiment includes an electric control box body 110, a mounting bracket 130 and a chassis 150. The chassis 150 is used to be set at the bottom of the air-conditioning housing 210, and the mounting bracket 130 is set on the chassis 150. The electric control box body 110 is set on the mounting bracket 130 and is located below the air duct in the air-conditioning housing 210.

[0047] It should be noted that the air-conditioning housing 210 mentioned in this embodiment refers to the housing of the vertical air conditioner 200, such as the housing of a cabinet air conditioner. The air-conditioning housing 210 has an air duct, and the electric control box mounting assembly 100 is integrally mounted in the air-conditioning housing 210 and is located below the air duct. Specifically, the lower half of the air-conditioning housing 210 is provided with a volute, a fan is arranged in the volute, the volute opens outward and forms an air duct, and the installation position of the electric control box body 110 in the vertical direction is lower than the volute, so that the electric control box body 110 is located below the air duct, avoiding the electric control box body 110 from affecting the air duct.

[0048] In this embodiment, an electric control component is disposed in the electric control box body 110, and the electric control component is used to control the operation of the fan in the volute. Of course, the electric control component here can also integrate other electric control functions, such as controlling the opening and closing of the air guide door.

[0049] The electric control box installation assembly 100 provided by the present invention fixes the electric control box body 110 on the chassis 150 through the installation bracket 130, so that the electric control box body 110 is moved from the middle of the whole machine to the bottom of the whole machine, and the electric control box body 110 is located below the air duct after being installed in place, avoiding the electric control box body 110 from obstructing the air duct, making the air duct streamline smoother and increasing the air volume.

[0050] See also Figures 4 to 7 The mounting bracket 130 includes a first frame 131 and a second frame 133, which are arranged on the chassis 150 in a relative manner, and the two ends of the electric control box body 110 are detachably connected to the first frame 131 and the second frame 133. Specifically, the first frame 131 and the second frame 133 are both convexly arranged on the chassis 150, and there is a spacing space between the first frame 131 and the second frame 133, and most of the bottom side of the electric control box body 110 is located above the spacing space, so that a heat dissipation cavity is formed at the bottom of the electric control box body 110. The electric control box body 110 is supported by the first frame 131 and the second frame 133 which are separately arranged, and the first frame 131 and the second frame 133 are respectively connected to the two ends of the electric control box body 110, so that there is a certain heat dissipation cavity between the bottom of the electric control box body 110 and the chassis 150, which improves the heat dissipation effect of the electric control and the electric control components in the body, and at the same time has a good bearing and fixing effect, which can effectively prevent the electric control box body 110 from shaking.

[0051] In this embodiment, the top of the first frame 131 and the top of the second frame 133 both have a mounting surface, and the electric control box body 110 is placed on the mounting surface and is detachably connected to the first frame 131 and the second frame 133. Specifically, the mounting surface is tilted outward, that is, the ends of the first frame 131 and the second frame 133 close to the front panel of the air-conditioning housing 210 are lower than the ends close to the rear panel, so that the electric control box body 110 can be tiltedly mounted on the first frame 131 and the second frame 133 during installation, which widens the upper installation space and facilitates the subsequent installation of screws.

[0052] In this embodiment, the first frame 131 and the second frame 133 are both riveted and fixed on the chassis 150. By riveting the first frame 131 and the second frame 133 to the chassis 150, the installation process is reduced, and the fixing effect of the first frame 131 and the second frame 133 is good, which prevents the first frame 131 and the second frame 133 from shaking.

[0053] In this embodiment, a first positioning convex plate 135 is further provided on a side of the first frame 131 away from the second frame 133, a second positioning convex plate 137 is further provided on a side of the second frame 133 away from the first frame 131, and a first mounting convex plate 110a and a second mounting convex plate 110b are respectively provided at both ends of the electric control box body 110, the first mounting convex plate 110a is detachably connected to the first positioning convex plate 135, and the second mounting convex plate 110b is detachably connected to the second positioning convex plate 137. By detachably connecting the first positioning convex plate 135 to the first mounting convex plate 110a, and detachably connecting the second positioning convex plate 137 to the second mounting convex plate 110b, the electric control box body 110 can be fixed to the mounting from the outer edges of both sides, with good installation space, and convenient installation of screws.

[0054] The first frame 131 includes an integrally arranged first support plate, a second support plate, a mounting plate and a positioning plate. The first support plate and the second support plate are arranged on the chassis 150 at intervals. The two ends of the mounting plate are connected to the first support plate and the second support plate respectively. The height of the first support plate relative to the chassis 150 is less than the height of the second support plate relative to the chassis 150, so that the mounting plate is arranged in an inclined manner. The mounting plate has a mounting surface and is detachably connected to the electric control box body 110. The positioning plate is arranged on a side away from the second frame 133 and extends upward. The first positioning convex plate 135 is fixedly connected to the top of the positioning plate, so that the first positioning convex plate 135 can be closer to the upper end surface of the electric control box body 110. The second frame 133 is symmetrically arranged with the first frame 131, and the structure is the same as that of the first frame 131, which will not be repeated here.

[0055] In this embodiment, by setting a positioning plate on the first frame 131 and the second frame 133, an assembly groove is formed between the two positioning plates, which can play a guiding role when assembling the electric control box body 110, and further quickly assemble the electric control box body 110 on the first frame 131 and the second frame 133.

[0056] The electric control box body 110 includes a box body 111 and a box cover 113.

The mounting folding plate 113a is buckled on the mounting flange 111a, so that the box cover 113 is covered on the box body 111. The box body 111 is detachably connected to the first frame 131 and the second frame 133. By buckling the mounting folding plate 113a on the mounting flange 111a, the box cover 113 is covered on the box body 111 and can maintain preliminary pre-fixation. When installing, there is no need to hold the box cover 113 by hand, which is convenient for subsequent installation of screws.

[0057] In this embodiment, since the mounting surface is inclined, the mounting flap is arranged on the upper edge of the box body 111, and the mounting folding plate 113a is also arranged on the upper edge of the box cover 113, so that the box cover 113 can be hung on the box body 111 through the mounting folding plate 113a, thereby achieving pre-positioning between the box cover 113 and the box body 111.

[0058] The first fixing convex plate 115 and the second fixing convex plate 117 are respectively provided at both ends of the box cover 113, and the first fixing convex plate 115 and the second fixing convex plate 117 are respectively detachably connected to both ends of the box body 111, and are respectively detachably connected to the first frame body 131 and the second frame body 133. The first fixing convex plate 115 and the second fixing convex plate 117 on the box cover 113 are connected to the mounting bracket 130 and the box body 111, so that the mounting bracket 130, the box body 111, and the box cover 113 can be connected as a whole, which increases the structural stability of the three and facilitates installation.

[0059] In this embodiment, the first mounting convex plate 110a and the second mounting convex plate 110b are respectively arranged at the two ends of the box body 111, and the first mounting convex plate 110a is connected to the first fixed convex plate 115, and the second mounting convex plate 110b is connected to the second fixed convex plate 117. At the same time, the first mounting convex plate 110a is connected to the first positioning convex plate 135, and the second mounting pattern is connected to the second positioning convex plate 137. That is, the first fixing convex plate 115, the first mounting convex plate 110a and the first positioning convex plate 135 are overlapped and connected in sequence, and the second fixing convex plate 117, the second mounting convex plate 110b and the second positioning convex plate 137 are overlapped and connected in sequence. Specifically, the first fixing convex plate 115, the first mounting convex plate 110a and the first positioning convex plate 135 are fixed together by screws, and the second fixing convex plate 117, the second mounting convex plate 110b and the second positioning convex plate 137 are fixed together by screws.

[0060] In this embodiment, the box body 111 includes a bottom plate and three side plates. The bottom plate is obliquely assembled on the first frame 131 and the second frame 133. The three side plates are respectively arranged on the upper, left and right sides of the bottom plate. The cover plate includes a top cover plate and a side cover plate. The top cover plate is arranged on the three side plates, and the side cover plate is arranged on the lower side of the bottom plate. The first fixed convex plate 115 and the second fixed convex plate 117 are respectively arranged on both sides of the top cover plate, and the first mounting convex plate 110a and the second mounting convex plate 110b are respectively arranged on the side plates on the left and right sides of the bottom plate. The upper side refers to the side of the bottom plate away from the bottom plate 150, and the lower side refers to the side of the bottom plate close to the bottom plate 150.

[0061] See also Figure 8 The electric control box body 110 is provided with a first positioning structure 170, and the mounting bracket 130 is provided with a second positioning structure 190, and the second positioning structure 190 cooperates with the first positioning structure 170 so that the electric control box body 110 can be detachably assembled on the mounting bracket 130. Specifically, the second positioning structure 190 is provided on both the first frame 131 and the second frame 133, and the first positioning structure 170 is provided at both ends of the electric control box body 110. Through the cooperation of the first positioning structure 170 and the second positioning structure 190, the electric control box body 110 can be conveniently assembled on the mounting bracket 130, and the connection stability between the electric control box body 110 and the mounting bracket 130 is ensured.

[0062] In this embodiment, the first positioning structure 170 includes at least one positioning flange 171, and the second positioning structure 190 includes at least one positioning hole 191. The positioning flange 171 is assembled in the positioning hole 191 to limit the position of the electric control box body 110. Specifically, a positioning hole 191 is provided on the first frame 131, and a positioning hole 191 is provided on the second frame 133. A positioning flange 171 is respectively provided at both ends of the bottom side of the electric control box body 110. The two positioning flanges 171 are respectively assembled in the two positioning holes 191. By assembling the positioning flanges 171 in the positioning holes 191, the electric control box body 110 and the mounting bracket 130 can be quickly assembled, which reduces the process and improves the installation efficiency.

[0063] In other preferred embodiments of the present invention, the positioning flange 171 can also be set on the first frame 131 and the second frame 133. At the same time, a positioning hole 191 is correspondingly opened at the bottom of the electric control box body 110. By assembling the positioning flange 171 in the positioning hole 191, quick assembly between the electric control box body 110 and the mounting bracket 130 can also be achieved.

[0064] Furthermore, the first positioning structure 170 further includes at least one first mounting screw hole 173, and the second positioning structure 190 further includes at least one second mounting screw hole 193. The first mounting screw hole 173 and the second mounting screw hole 193 are aligned after the positioning flange 171 is assembled in the positioning hole 191, and a connecting piece (not shown) is also assembled on the electric control box body 110, and the connecting piece passes through the first mounting screw hole 173 and the second mounting screw hole 193 in sequence, so that the electric control box body 110 and the mounting bracket 130 can be detachably connected. Through the dual positioning structure of the positioning flange 171 and the screw hole, the connection between the electric control box body 110 and the mounting bracket 130 is made more secure, and at the same time, the screw holes are aligned after the positioning flange 171 is assembled. In actual installation, the positioning flange 171 can be quickly assembled and then the connecting piece can be assembled, which greatly improves the assembly efficiency.

[0065] In this embodiment, the connecting member is a screw. During actual installation, the electric control box body 110 is first hung on the first frame 131 and the second frame 133 through the assembly action of the positioning flange 171 and the positioning hole 191. At the same time, the first mounting screw hole 173 and the second mounting screw hole 193 can be aligned with each other, and the electric control box body 110 is fixed to the first frame 131 and the second frame 133 by screws.

[0066] It should be noted that the pre-fixing effect of the positioning flange 171 and the positioning hole 191 can also enable the first mounting protrusion 110a and the first positioning protrusion 135, and the second mounting protrusion 110b and the second positioning protrusion 137 to be positioned and aligned. After closing the box cover 113, it is only necessary to align the first fixing protrusion 115 and the second fixing protrusion 117, which is very convenient.

[0067] See also Figures 9 to 12 The electric control box body 110 is provided with a plurality of wire holes 119, which are arranged at intervals on the side of the electric control box body 110, and the plurality of wire holes 119 are not on the same side.

The third through hole 119c and the fourth through hole 119d are both provided on the side wall of the electric control box body 110. The side wall where the third through hole 119c and the fourth through hole 119d are located is adjacent to the side wall where the first through hole 119a is located, and is adjacent to the side wall where the second through hole 119b is located. By providing the first through hole 119a, the second through hole 119b, the third through hole 119c and the fourth through hole 119d, the four wire-passing holes 119 are respectively located at three side walls, so that the wires of different components can be routed separately, and the lines can easily pass through the routing holes, making wiring simpler and clearer, and not easy to cause confusion, thereby improving wiring efficiency.

[0069] In this embodiment, the first through hole 119 a and the second through hole 119 b are respectively formed on the left and right side plates of the box body 111 , and the third through hole 119 c and the fourth through hole 119 d are spaced apart and formed on the side cover plate of the box cover 113 .

[0070] In other preferred embodiments of the present invention, the number of the wire holes 119 may be 3 or 5, etc., and they are opened on different side walls of the electric control box body 110. The specific number of the installation side walls is not specifically limited herein.

[0071] In summary, the present embodiment provides an electric control box installation assembly 100, which avoids the electric control box body 110 from obstructing the air duct by installing the electric control box body 110 below the air duct, making the air duct streamline smoother and increasing the air volume. At the same time, the electric control box body 110 is pre-fixed by positioning the flange 171 and the positioning hole 191, which is convenient for assembling screws, reduces the process, is simple and labor-saving, and improves the installation efficiency. At the same time, by opening the wire holes 119 on different side walls of the electric control box body 110, the line can easily pass through the wiring hole, making wiring simpler and clearer, less likely to cause confusion, and improving the wiring efficiency.
