Optionally, the pressure-bearing net is made of rigid linear material spirally distributed.

As a result, the distance between the linear materials of the pressure-bearing net is gradually changed, thereby moving the vortex shedding frequency generated by the mutual interference between the airflow and the air outlet protection net to the low-frequency direction, thereby reducing the aerodynamic noise of the fan, which is beneficial to The overall noise reduction of the air conditioner and air conditioner group.

The outer edge of the pressure-bearing net is provided with pressure-bearing strips, and the pressure-bearing strips and the spokes are fixedly connected.

Detailed ways

The existing top-out air conditioners discharge air upward, and the air outlet is located at the top of the air conditioner. The wire mesh at the existing air outlet is a plane type, and the plane type iron wire mesh has poor compressive capacity, resulting in bumping and squeezing during transportation. When pressed, it is easy to cause the wire mesh to dent.

In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In addition, a brief description of the orientation involved in this specific embodiment is made: the following refers to the "front", "rear", "upper", "lower", "left", "right" and other indications of each structural member The direction or positional relationship refers to the orientation or positional relationship shown in the accompanying drawings; the positional relationships of "top" and "bottom" are only for the convenience and simplification of description, and do not indicate or imply that the device referred to must have The particular orientation, construction and operation in the particular orientation are therefore not to be construed as limitations of the invention.

The horizontal plane involved in this embodiment is the reference datum plane, and the horizontal plane is parallel to the ground. This embodiment describes the structure of the three-dimensional pressure-resistant protective net and the air conditioner after the assembly is completed.

As shown in Figures 1-3, a three-dimensional anti-compression protective net includes spokes 1, and the spokes 1 are made of metal material, so as to have high strength and improve the anti-compression ability of the three-dimensional anti-compression protective net. 1. It is made of iron bars, which are cheap and easy to obtain, and have low production costs. The outer surface of the iron bars can be sprayed with anti-rust paint, and the treatment process is simple, which not only prolongs its service life, but also makes the appearance of the air conditioner more beautiful. . The spokes 1 are provided with pressure-bearing nets 2, and the spokes 1 and the pressure-bearing nets 2 are attached, connected, clipped or welded together. The pressure-bearing net 2 is used to disperse the pressure it bears, so that the pressure is evenly distributed in each position of the spoke 1, so as to avoid the partial damage of the pressure-bearing net 2 or the spoke 1 caused by the pressure concentration, thereby improving the overall performance of the three-dimensional pressure-resistant protective net. Stress resistance. When the spokes 1 and the pressure-bearing net 2 are attached and connected together, it is more convenient for the pressure-bearing net 2 to disperse and transmit the pressure on itself, but the pressure-bearing net 2 is easily deformed and loses its own function of dispersing pressure. When the spokes 1 and the pressure-bearing net 2 are snapped together, the pressure-bearing net 2 is not easy to be loosely deformed and can carry out good pressure dispersion, but the processing technology is complicated, and the structural strength of the pressure-bearing net 2 or the spoke 1 itself will be reduced, so that the three-dimensional structure cannot be made. The anti-compression net achieves the ideal anti-compression capacity. Preferably, in this embodiment, the pressure-bearing net 2 and the spokes 1 are welded together, so that the shape of the pressure-bearing net 2 is fixed, and the ability of the pressure-bearing net 2 to disperse the pressure is better exerted, and the overall three-dimensional pressure-resistant protective net is also More compact and beautiful. The diameter of the spoke 1 is 1.5-2.5 times the diameter of the helical iron wire of the pressure-bearing mesh 2, preferably, the diameter of the spoke 1 is 2 times the diameter of the helical iron wire of the pressure-bearing mesh 2, within the load range of the pressure-bearing mesh 2 , Spoke 1 effectively shares the pressure on the pressure-bearing net 2, and the spoke 1 and the pressure-bearing net 2 coordinate and cooperate to bear the pressure as a whole, maximize the functional efficiency of the spoke 1 and the pressure-bearing net 2, and have better support capability . The outer edge of the pressure-bearing net 2 is provided with a pressure-bearing strip 3, and the pressure-bearing strip 3 is suitable for connecting with the top cover. round. Preferably, the pressure-bearing bar 3 is made of an iron bar, and the surface is sprayed with anti-rust paint, which is low in cost, simple and durable. And the pressure-bearing strip 3 is composed of a multi-segment arc iron strip, and the two ends of the arc iron strip are welded together with the spokes 1 on both sides respectively. The spokes 1 are suitable for connecting with the top cover of the air conditioner. In order to facilitate the positioning and installation, the ends of the spokes are integrally bent and formed to form a mounting portion. The top cover of the air conditioner is provided with a fixing groove, and the mounting portion is embedded in the fixing groove. There are mounting holes on the top, and the top cover is screwed together with fixing bolts through the mounting holes. Since the pressure-bearing strip 3 is welded with the mounting part of the spoke 1, the end of the pressure-bearing strip 3 is bent downward and the mounting part is welded together, and the end of the pressure-bearing strip 3 and the mounting part of the spoke 1 are embedded together In the fixing groove, the middle of the pressure-bearing strip 3 is horizontal, which is convenient for the pressure-bearing strip 3 and the top cover to fit together, thereby increasing the contact area between the pressure-bearing strip 3 and the top cover, increasing the compression resistance area, and improving the resistance to compressive strength.

The pressure-bearing net 2 disperses the pressure on the spokes 1, and conducts the pressure to the pressure-bearing bars 3 through the spokes 1, and then disperses the pressure to the top cover of the air conditioner. The problem of pressure difference resistance of the protective net of the existing top-out air conditioner is solved.

At present, the spokes 1 are all linear structures, and the two ends of the spokes are fixed connection ends, which will cause the pressure to concentrate on the two ends of the spokes 1. The ends of the spokes 1 are usually welded, which is more likely to cause the spokes to fall off. The spokes 1 themselves play a limited role in the pressure transmission process, so the ability of the spokes 1 to withstand pressure is small.

As shown in FIG. 4 , the spoke 1 includes a first connecting section 11 (L1), a transition section 12 (L2) and a horizontal section 13 (L3) which are connected in sequence, wherein the first connecting section 11 (L1) is the first connecting section 11 (L1) relative to the horizontal plane. An included angle a is inclined, the transition section 12 (L2) is inclined at a second angle b relative to the horizontal plane, and the horizontal section 13 (L3) is arranged parallel to the horizontal plane. In the vertical direction, it is designed into three sections. In the case of enhancing the compressive ability of the spoke 1, the overall height of the three-dimensional anti-compression protective net should be reduced as much as possible, so as to avoid the three-dimensional anti-compressive protective net from being too protruding and more likely to be bumped.

The spokes are designed as a three-segment structure, so that multiple pressure support points are formed on the spokes 1 to disperse and transmit the pressure to avoid pressure concentration, thereby improving the compression resistance of the spokes 1, and the horizontal section 13 and the fixed plate 4 are parallel to each other , it is easy to be welded with the fixing plate 4, the contact area is large, the welding is firm, and the overall compression resistance of the three-dimensional compression protection net is improved.

When the three-dimensional pressure-resistant net is compressed, the pressure from the vertical direction is first transmitted to the transition section 12 of the spoke 1 through the horizontal section 13 of the spoke 1, and finally transmitted to the first connecting section 11 of the spoke 1. A connecting section 11 is fixedly connected with the pressure-bearing strip 3 as a whole, so that the pressure of the first connecting section 11 of the spoke 1 is transmitted to the pressure-bearing strip 3, so that the top cover of the indoor unit can bear the pressure of the three-dimensional pressure-resistant protective net .

The first included angle a is greater than the second included angle b.

The first connecting section 11 and the transition section 12 of the spoke 1 have different bending degrees, and the bending degree of the first connecting section 11 is greater than that of the transition section 12. When the horizontal section 13 is compressed, the spoke 1 has better pressure transmission Therefore, most of the pressure is transmitted to the pressure-bearing strips 3 to avoid damage to the spokes 1 caused by excessive pressure, and further improve the compression resistance of the spokes 1 .

The range of the first included angle a is: 10-30°, and the range of the second included angle b is: 0-10°.

Within this angle range, the compression resistance enhancement effect of the spoke 1 is the best, and the overall height of the three-dimensional compression protection net is relatively small.

There are a plurality of spokes 1, and the plurality of spokes 1 radiate outward from the center of the pressure-bearing net 2. It can be understood that the plurality of spokes 1 are arranged symmetrically with the center of the pressure-bearing net 2, so that the support of the pressure-bearing net 2 is more balanced. , Preferably, the number of spokes 1 is 8, so that under the condition of sufficient supporting strength for the pressure-bearing net 2, there is sufficient clearance between the spokes 1 to avoid noise.

At present, the air conditioner pressure nets on the market are composed of equal-diameter steel wires, concentric rings and radial straight lines at equal intervals to form a circular mesh surface. It is relatively poor, and it is easy to cause mutual interference between the air flow of the fan and the pressure-bearing net, which increases the frequency of the generated vortex shedding, resulting in a relatively high aerodynamic noise of the air conditioner fan.

The present invention improves the structure of the pressure-bearing net 2, the pressure-bearing net 2 is made of linear materials spirally distributed, and the spacing between the linear materials of the pressure-bearing net 2 is gradually changed, so that the air flow and the air outlet protection net are mutually The vortex shedding frequency generated by the interference moves to the low frequency direction, thereby reducing the aerodynamic noise of the fan, which is beneficial to the reduction of the overall noise of the air conditioner and air conditioner group.

It can be understood that the spacing between the linear materials in the middle part of the pressure-bearing net 2 corresponding to the airflow with the maximum wind speed is larger than the spacing between the linear materials in other parts, which further reduces noise.

The linear material of the pressure-bearing net 2 can be metal wire, wire, or plastic wire or wire. In this embodiment, preferably, the linear material of the protective net is iron wire, which is cheap and easy to obtain, and has a low production cost. In order to avoid the problem that the exposed iron wire is prone to corrosion, the outer surface of the iron wire can be sprayed with anti-rust paint, which not only prolongs its service life, but also makes the appearance of the air conditioner more beautiful. The diameter of the iron wire is 2-5mm, within this range. , the ability of the iron wire to disperse the pressure is enough to match the pressure ability of the spokes, and the distance between the linear materials is 8-12mm. The spacing is large enough to reduce noise.

Optionally, considering that the pressure-bearing net 2 has sufficient strength, the pressure-bearing net 2 can also be formed by spirally arranged guide vanes, and the guide vanes can be made of iron sheets, so as to have a better guide effect. , to further reduce noise.

As shown in FIG. 5 , a fixing plate 4 is also included. The fixing plate 4 is arranged in the center of the pressure-bearing net 2 , and the fixing plate 4 is fixedly connected with the spokes 1 .

The setting of the fixing plate 4 enables the spokes 1 to have the basis for a fixed connection, and when the three-dimensional anti-compression protective net is pressed, the pressure from the vertical direction is first transmitted to each spoke 1 through the fixed plate 4, and the three-dimensional anti-compression protective net is first transmitted to each spoke 1. Preliminarily disperse the pressure of the mesh, thereby reducing the pressure on the pressure-bearing mesh. Because the fixed plate 4 is welded with a plurality of spokes 1, the connection strength is high, and it can support a large pressure, thereby improving the overall resistance of the three-dimensional pressure-resistant mesh. Pressure capacity, the fixed plate 4 is a circular structure, which is convenient for the setting of the spokes 1, the length is consistent, and the appearance is beautiful. On the surface of the fixing plate 4 facing the inside of the air conditioner. The purpose of this structure is to make the entire structure of the pressure-bearing net 2 more beautiful. Because, all the welding parts of the spokes 1 on the fixing plate 4 will not be exposed on the exterior of the air conditioner.

The fixing plate 4 is provided with a plurality of circumferential reinforcing ribs 41 , and a circular reinforcing convex hull 42 is designed at the center of the fixing plate 4 .

By further improving the structure of the fixing plate 4, the strength of the fixing plate 4 itself is enhanced, thereby improving the compressive capacity of the fixing plate 4 itself. The center of the circle is symmetrically arranged, the appearance is stable, and it is more beautiful, which is in line with the aesthetic concept of the general public.

The ratio of the diameter of the circular reinforcing convex hull 42 to the diameter of the fixed plate 4 is in the range of 1/3 to 2/3, and the ratio of the arc length of the circumferential reinforcing rib 41 to the circumference of the fixed plate 4 is in the range of: 1 /12～2/12.

Within this range, the circular reinforcing convex hull 42 and the circumferential reinforcing rib 41 have the best strengthening effect on the fixing plate 4 and will not affect the structure of the fixing plate 4 itself, so that the fixing plate 4 has higher strength.

Further, according to the weight of the product, in conjunction with the assembled state of the fixed plate 4 and the pressure-bearing net 2, relevant tests were carried out. Table 1 is the test result of the common pressure-bearing net, Table 2 is the test result of the common fixed plate, and Table 3 is this Test results of the invented pressure net:
