[0037] In the prior art, when there is an assembly gap in the air conditioner, a decorative structure, such as a decorative ring, is generally required to cover the gap. However, the current decorative ring serves primarily a decorative purpose and lacks waterproofing. In colder environments, such as freezing rain, water can seep through the decorative ring. This freezing rain can easily flow into the outdoor unit through the gap between the decorative ring and the outdoor unit housing and freeze. This ice can collide with the rotating motor blades, causing damage.
[0038] In view of this, the present embodiment provides an outdoor unit of a HVAC equipment, which aims to solve the above technical problems by arranging a decorative ring on the shell. The annular guide portion 11 of the decorative ring guides most of the rainwater to flow away from the fan blades 4, while making it difficult for water to flow from the inner wall of the decorative ring 1 into the interior of the shell 2, thereby reducing the risk of ice colliding with the rotating motor fan blades 4.
[0039] like Figures 1 to 8 As shown, according to the embodiment of the present invention, an outdoor unit of HVAC equipment is proposed, which includes a shell 2 and a decorative ring 1. The decorative ring 1 includes a decorative ring body 10 arranged in a ring shape. The decorative ring 1 includes a decorative ring body 10, and the decorative ring body 10 has a first side 100 and a second side 101 opposite to each other in the axial direction. An annular guide portion 11 extending radially outward is provided on the outer peripheral surface of the decorative ring body 10. From the second side 101 to the first side 100, the radial size of the annular guide portion 11 gradually increases. The annular guide portion 11 abuts against the shell 2, and there is an axial gap between the first side 100 and the shell 2. The shell 2 includes a front panel 20, which has an air outlet. A fan blade 4 is arranged in the shell 2, and the fan blade 4 is arranged opposite the air outlet. An air outlet mesh cover 3 is detachably connected to the air outlet. The front panel 20 has an annular air guide flange extending axially inward, and the annular air guide flange forms an air guide ring 21. The decorative ring 1 is installed on the front panel 20, and an axial gap is formed between the inner wall of the air guide ring 21 and the first side 100.
[0040] The decorative ring 1 is made of rubber and is an integrally formed structure, which can be realized by injection molding, for example, and is easy to process and has low cost.
[0041] The outdoor unit of the heating and ventilation equipment of the present invention is provided with a decorative ring 1 on the shell 2, and the decorative ring 1 is provided with an annular guide portion 11. The annular guide portion 11 abuts against the outer wall of the shell 2 of the outdoor unit, and the annular guide surface is inclined from the second side 101 to the first side 100. When it rains, the direction of water flow is as follows Figure 4As indicated by the middle arrow, due to gravity, most rainwater flows away from the fan blades 4 through the guidance of the annular guide 11 and flows down through the decorative ring 1. At the same time, due to the axial gap formed between the first side 100 of the decorative ring body 10 and the housing 2, the first side 100 of the decorative ring 1 and the housing 2 are not in contact, making it difficult for water to flow from the inner wall of the decorative ring 1 into the housing 2. This reduces the risk of ice colliding with the rotating motor blades 4 and ensures the normal operation of the outdoor unit. Furthermore, the decorative ring 1 also serves a decorative purpose, enhancing the appearance of the front panel 20.
[0042] In some embodiments of the present invention, Figure 7 As shown, the axial gap between the inner wall of the air guide ring 21 and the first side 100 is d, and the value range of d is 5mm≤d≤10mm. In this embodiment, the axial gap d is preferably 7mm. In other embodiments, d can also be 5mm, 6mm, 8mm, 10mm, etc.
[0043] like Figure 3 As shown, the height of the decorative ring 1 protruding from the front panel 20 is c, and the value range of the height c is 30mm≤c≤40mm, for example, it can be 30mm, 32mm, 35mm, 38mm, 40mm, etc., and can be set according to the height of the air outlet mesh cover 3 or the waterproof requirements. For example, if the height of the air outlet mesh cover 3 is higher, the height of the decorative ring 1 can be increased, or by increasing the height of the decorative ring 1, the waterproof effect can be further improved.
[0044] In some embodiments of the present invention, a plurality of avoidance grooves 15 are circumferentially provided on the first side 100. The avoidance grooves 15 are used to axially avoid the air outlet grille 3. Specifically, a plurality of mounting portions are circumferentially spaced apart on the air outlet grille 3, each of which is provided with bolt holes. The air outlet grille 3 is connected to the front panel 20 via bolts. The first side 100 of the decorative ring body 10 is circumferentially spaced apart with a plurality of avoidance grooves 15. The plurality of avoidance grooves 15 are provided in a one-to-one correspondence with the plurality of mounting portions. The avoidance grooves 15 can axially avoid the mounting portions, allowing the annular guide portion 11 to be installed closely against the front panel 20, thereby improving the waterproof effect.
[0045] In some embodiments of the present invention, the decorative ring 1 further includes a plurality of reinforcement portions 12, each of which is connected to the decorative ring body 10 and the annular guide portion 11. The plurality of reinforcement portions 12 are spaced apart along the circumference of the decorative ring body 10. Specifically, the reinforcement portions 12 include reinforcing ribs connected to the decorative ring body 10 and the annular guide portion 11. The provision of the reinforcement portions 12 can improve the overall strength of the decorative ring 1, thereby enhancing the strength and stability of the decorative ring 1 and increasing the service life of the decorative ring 1.
[0046] In some embodiments of the present invention, the decorative ring 1 is further provided with a connecting portion 13, and the housing 2 is provided with a connecting and mating portion 22. The connecting portion 13 and the connecting and mating portion 22 are mated and connected. The provision of the connecting portion 13 and the connecting and mating portion 22 facilitates the installation of the decorative ring 1 and allows for quick connection and removal of the decorative ring 1 and the front panel 20, thereby improving assembly and disassembly and maintenance efficiency.
[0047] In some embodiments of the present invention, one of the connecting portion 13 and the connecting and fitting portion 22 is configured as a mounting portion 130, and a first threaded hole 131 is provided on the mounting portion 130. The other of the connecting portion 13 and the connecting and fitting portion 22 is a second threaded hole 220. A bolt passes through the first threaded hole 131 and the second threaded hole 220 to connect to the mounting portion 130. In this embodiment, the mounting portion 130 is provided on the decorative ring 1, and the annular guide portion 11 is recessed toward the decorative ring body 10 to form the mounting portion 130. The mounting portion 130 is provided with a first threaded hole 131. There are multiple mounting portions 130 and multiple first threaded holes 131. The multiple mounting portions 130 are spaced apart along the circumference of the decorative ring 1, and the multiple first threaded holes 131 are provided in a one-to-one correspondence with the multiple mounting portions 130. The front panel 20 is provided with multiple second threaded holes 220 corresponding to the first threaded holes 131. When installing the decorative ring 1, align the first threaded hole 131 and the second threaded hole 220, then use screws to pass through the first threaded hole 131 and the second threaded hole 220 in sequence, and tighten the screws. After the screws are tightened, the nut end is placed in the installation part 130 and fixed tightly.
[0048] In other embodiments, one of the connecting portion 13 and the connecting mating portion 22 may also be a buckle, and the other may be a slot. The decorative ring 1 may be mounted on the front panel 20 by cooperating with the buckle and the slot. Alternatively, a screw may be passed through the second threaded hole 220 and the first threaded hole 131 in sequence from the side of the front panel 20 away from the decorative ring 1 to fix the decorative ring 1 to the front panel 20. This connection method allows the screw to be installed from inside the shell 2, and the screw cannot be seen from the outside, further improving the appearance.
[0049] In some embodiments of the present invention, the decorative ring 1 is provided with a positioning portion 14, and the housing 2 is provided with a positioning and mating portion 23. The positioning and mating portion 23 is positioned and connected to the positioning portion 14, and guides and cooperates with the positioning portion 14 during the connection process.
