Preferably, the spokes 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. The treatment process is simple, which not only prolongs its service life, but also makes the appearance of the air conditioner more beautiful . The spoke 1 is provided with a pressure-bearing mesh 2, and the spoke 1 and the pressure-bearing mesh 2 are bonded, clamped or welded together. The pressure 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 local damage of the pressure net 2 or the spoke 1 caused by the pressure concentration, thereby improving the overall performance of the three-dimensional compression protection net. Stress resistance. When the spokes 1 and the pressure net 2 are bonded together, it is more convenient for the pressure net 2 to disperse and transmit the pressure on itself, but in this way the pressure net 2 is easy to loosen and deform, thereby losing its own function of dispersing pressure. When the spoke 1 and the pressure net 2 are clamped, the pressure net 2 is not easy to loosen and deform and can perform good pressure dispersion, but the processing technology is complicated, and the structural strength of the pressure net 2 or the spoke 1 itself will be reduced, so that the three-dimensional The anti-compression protection net achieves the ideal anti-compression ability. Preferably, in this embodiment, the pressure-bearing mesh 2 and the spokes 1 are welded together, so that the shape of the pressure-bearing mesh 2 is fixed, and the ability of the pressure-bearing mesh 2 to disperse pressure is better exerted, and the three-dimensional pressure-resistant protective mesh as a whole is also More compact and beautiful. The diameter of the spoke 1 is 1.5-2.5 times the diameter of the spiral iron wire of the pressure-bearing network 2, preferably, the diameter of the spoke 1 is twice the diameter of the spiral iron wire of the pressure-bearing network 2, within the load range of the pressure-bearing network 2 , the spoke 1 can effectively share the pressure on the pressure net 2, and the spoke 1 and the pressure net 2 coordinate and cooperate to bear the pressure as a whole, so as to maximize the function and efficiency of the spoke 1 and the pressure net 2, and have better supporting capacity . The outer edge of the pressure-bearing network 2 is provided with a pressure-bearing strip 3, which is suitable for connecting with the top cover. round. Preferably, the pressure-bearing bar 3 is made of iron bar, and the surface is sprayed with anti-rust paint, which is low in cost, simple and durable. Moreover, the pressure-bearing bar 3 is composed of multiple sections of arc iron bars, and the two ends of the arc iron bars are respectively welded together with the spokes 1 on both sides. Spoke 1 is suitable for connection with the top cover of the air conditioner. In order to facilitate positioning and installation, the ends of the spokes are integrally bent to form a mounting part. The top cover of the air conditioner is provided with a fixing groove, and the mounting part is embedded in the fixing groove. There are mounting holes on the upper part, and the fixing bolts are screwed together through the mounting holes and the top cover. Since the pressure-bearing strip 3 is welded together with the installation part of the spoke 1, the end of the pressure-bearing strip 3 is bent downward and welded together with the installation part, and the end of the pressure-bearing strip 3 and the installation part of the spoke 1 are embedded together. In the fixing groove, the middle part 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 pressure-resistant area, and improving the resistance. compressive strength.

The pressure net 2 disperses the pressure on the spoke 1, and transmits the pressure to the pressure strip 3 through the spoke 1, and then disperses the pressure to the top cover of the air conditioner, and the pressure resistance area increases, which greatly improves the pressure resistance of the product. The problem of anti-pressure difference of the protective net of the existing top outlet air conditioner is solved.

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

As shown in Figure 4, the spoke 1 includes a first connecting section 11 (L1), a transition section 12 (L2) and a horizontal section 13 (L3) connected in sequence, wherein, the first connecting section 11 (L1) is arranged at the first An included angle a is arranged obliquely, the transition section 12 (L2) is arranged obliquely at a second included angle b relative to the horizontal plane, and the horizontal section 13 (L3) is arranged parallel to the horizontal plane. Considering the height of the three-dimensional compression protection net, the spokes 1 It is designed into three sections in the vertical direction. In the case of enhancing the compression resistance of the spoke 1, the overall height of the three-dimensional compression protection net is reduced as much as possible to avoid the three-dimensional compression protection net from being too protruding, which is more likely to cause bumps.

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

When the three-dimensional anti-compression protective net is under pressure, 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 to the first connecting section 11 of the spoke 1, and the first connecting section 11 of the spoke 1. A connecting section 11 is fixedly connected with the pressure-bearing bar 3 as a whole, so that the pressure of the first connecting section 11 of the spoke 1 is transmitted to the pressure-bearing bar 3, so that the top cover of the indoor unit bears the pressure of the three-dimensional pressure-resistant protection net .

The first included angle a is larger 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 under pressure, the spoke 1 has better pressure transmission effect, and transmit most of the pressure to the pressure-bearing strip 3, avoid damage to the spoke 1 caused by excessive pressure, and further improve the compression resistance of the spoke 1.

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

In this embodiment, preferably, the linear material of the protective net is iron wire, which is cheap and easy to obtain, and has a lower 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 sufficient to match the pressure bearing capacity of the spokes, and the distance between the linear materials is 8-12mm. The spacing is large enough to reduce noise.
