[0032] Air conditioning is an air conditioner, which refers to a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. Air conditioning usually includes an indoor air conditioning unit and an outdoor air conditioning unit. The indoor air conditioning unit includes an evaporator, an indoor fan and an electric control box (or an electric control box). The outdoor air conditioning unit includes an outdoor unit casing, a fan bracket and an outdoor fan installed in the fan bracket.
[0033] In the prior art fan bracket (or fan fixing structure), the outdoor fan is fixed on the fan bracket. The fan bracket has a natural frequency. When the fan rotates, it is easy to resonate with the fan bracket, thereby generating a large noise.
[0034] In order to solve the above-mentioned problem, the present application provides a fan bracket and an air-conditioning outdoor unit, wherein an anti-vibration part is arranged on the frame of the fan bracket, and the anti-vibration part is in contact with the condenser of the air-conditioning outdoor unit, and the outdoor fan is installed on the mounting hole of the frame; thereby, the anti-vibration part supports the frame, and the lateral support of the anti-vibration part changes the stress condition of the frame, and at the same time changes the local stiffness of the frame to change the natural frequency of the frame, thereby eliminating the resonance between the outdoor fan and the frame and reducing the noise of the air-conditioning outdoor unit.
[0035] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0036] On the one hand, the present application provides a fan bracket, referring to Figures 1 to 6 The fan bracket includes a frame 100 and at least one anti-vibration member 200. The head and tail ends of the frame 100 are respectively used to connect with the air-conditioning outdoor unit body 1. The middle part of the frame 100 is provided with a mounting hole 111 for installing the outdoor fan 2. The anti-vibration member 200 is arranged on a side of the frame 100 away from the outdoor fan 2 and is used to abut against the condenser 3 of the air-conditioning outdoor unit.
[0037] The frame 100 is located inside the air conditioner outdoor unit. In the prior art, the bottom of the frame 100 is connected to the bottom of the air conditioner outdoor unit body 1, the top of the frame 100 is connected to the top of the air conditioner outdoor unit, and the outdoor fan 2 is installed on the mounting hole 111 of the frame 100, so that the outdoor fan 2 is in a suspended state. The frame 100 is also fixedly connected only at the upper and lower ends.
[0038] The outdoor fan 2 includes a fan body and a motor. The motor is connected to the frame 100 by bolts through the mounting hole 111. The fan body is mounted on the output shaft of the motor. The condenser 3 of the air conditioner outdoor unit is located on the side of the frame 100 away from the fan body.
[0039] In one embodiment of the present application, through vibration simulation analysis, the frame 100 has a natural frequency of 90 Hz, which coincides with the triple frequency of the outdoor fan 2600 rpm, wherein the triple frequency of the outdoor fan 2 = (number of fan blades x fan speed / 60 seconds) x3.
[0040] Therefore, in the present application, the triple frequency of the outdoor fan 2 = (3x600 / 60)x3 = 90 Hz.
[0041] Therefore, when the rotation speed of the outdoor fan 2 is 600 rpm, there is resonance between the outdoor fan 2 and the frame 100, thereby generating a relatively large noise.
[0042] By adopting the above technical solution, an anti-vibration member 200 is arranged on the frame 100, and the anti-vibration member 200 is in contact with the condenser 3 of the air-conditioning outdoor unit, and the outdoor fan 2 is installed on the mounting hole 111 of the frame 100; thereby, the anti-vibration member 200 forms a support for the frame 100, and the lateral support of the anti-vibration member 200 changes the stress condition of the frame 100, and at the same time changes the local stiffness of the frame 100 to change the natural frequency of the frame 100, thereby eliminating the resonance between the outdoor fan 2 and the frame 100 and reducing the noise of the air-conditioning outdoor unit.
[0043] Exemplarily, one anti-vibration member 200 is provided. Of course, in other embodiments, multiple anti-vibration members 200 may be provided on the frame 100 to further improve the supporting effect of the frame 100, reduce the possibility of resonance between the frame 100 and the outdoor fan 2, improve the stability of the outdoor fan 2, and reduce noise.
[0044] In some embodiments, the anti-vibration member 200 includes an anti-vibration plate, one end of which is connected to the frame 100 and the other end of which is used to abut against the shower head of the air conditioner outdoor unit.
[0045] Reference Figure 2 and Figure 3 The anti-vibration plate is arranged on the frame 100 in the horizontal direction and abuts against the cold shower of the air conditioner outdoor unit, thereby realizing the lateral fixed support of the frame 100. The force condition of the frame 100 is changed, and the local stiffness of the frame 100 is changed to change the natural frequency of the frame 100, thereby eliminating the resonance between the outdoor fan 2 and the frame 100 and reducing the noise of the air conditioner outdoor unit.
[0046] There is a gap between the anti-vibration plate and the end of the frame 100, so that the anti-vibration plate is located near the mounting hole 111 in the middle of the frame 100. When the anti-vibration plate abuts against the side wall of the condenser 3 of the air conditioner outdoor unit, a lateral supporting force is applied to the frame 100, thereby reducing the vibration of the frame 100 and reducing the noise generated when the outdoor fan 2 rotates.
[0047] Exemplarily, the anti-vibration plate is located between the mounting hole 111 and the bottom of the frame 100. Thus, the anti-vibration plate supports the bottom of the frame 100 after the outdoor fan 2 is installed, thereby improving the supporting effect.
[0048] In other embodiments, the anti-vibration plate is located between the mounting hole 111 and the top of the frame 100 .
[0049] Furthermore, two anti-vibration plates are provided, and the two anti-vibration plates are symmetrically arranged on both sides of the mounting hole 111 , so as to further improve the supporting effect and reduce the vibration of the frame 100 .
[0050] In some embodiments, the anti-vibration plate is L-shaped.
[0051] It can be understood that one side edge of the L-shaped anti-vibration plate abuts against the side wall of the condenser 3 of the air-conditioning outdoor unit, thereby increasing the contact area between the anti-vibration plate and the condenser 3 of the air-conditioning outdoor unit, improving the stability of the anti-vibration plate support, and reducing damage to the condenser 3 of the air-conditioning outdoor unit.
[0052] Exemplarily, through holes are opened on the anti-vibration plate to reduce the weight of the anti-vibration plate while ensuring the strength of the anti-vibration plate.
[0053] In the present application, the anti-vibration plate is integrally formed with the frame 100. Of course, in other embodiments, the anti-vibration plate can be welded and fixed to the frame 100, or can be fixed to the frame 100 by bolts, and there is no excessive restriction here, as long as the connection between the anti-vibration plate and the frame 100 can be achieved.
[0054] In some embodiments, reference Figure 2 , Figure 4 and Figure 5 The frame 100 includes a mounting vertical plate 110, a first connecting plate 120 and a second connecting plate 130. The first connecting plate 120 is horizontally arranged at the top of the mounting vertical plate 110 and is used to connect with the air conditioner outdoor unit body 1. The second connecting plate 130 is horizontally arranged at the bottom of the mounting vertical plate 110 and is used to connect with the air conditioner outdoor unit body 1. The mounting hole 111 is opened on the mounting vertical plate 110.
[0055] The motor of the outdoor fan 2 is inserted into the mounting hole 111 and fixed to the mounting hole 111 by bolts. The outdoor fan 2 is mounted on the output shaft of the motor to achieve the installation of the outdoor fan 2.
[0056] The mounting plate 110 is arranged in the vertical direction, the first connecting plate 120 and the second connecting plate 130 are both located on the same side of the mounting plate 110, the first connecting plate 120 is connected to the top of the mounting plate 110 in the horizontal direction, and the second connecting plate 130 is connected to the bottom of the mounting plate 110 in the horizontal direction. The first connecting plate 120 and the second connecting plate 130 are both located on the side away from the condenser.
[0057] Exemplarily, the first connecting plate 120 , the mounting vertical plate 110 , and the second connecting plate 130 are all formed in one piece, and the outdoor fan 2 is located on the same side of the first connecting plate 120 and the second connecting plate 130 .
[0058] Among them, a plurality of positioning holes are opened on the second connecting plate 130, and a plurality of positioning columns are preset on the base of the air conditioner outdoor unit. The plurality of positioning holes are inserted in the corresponding positioning columns to realize the positioning of the second connecting plate 130 and limit the movement of the second connecting plate 130.
[0059] In addition, the upper side surface of the first connecting plate 120 abuts against the top of the outer shell of the air-conditioning outdoor unit. A fixing portion is provided at one end of the first connecting plate 120 away from the mounting vertical plate 110. The fixing portion is a vertical plate structure and is provided with a plurality of bolt holes for connecting to the front cover of the air-conditioning outdoor unit through bolts.
[0060] In some embodiments, reference Figure 2 and Figure 4 A vent 112 is provided on the mounting vertical plate 110 , a flange portion is provided around the vent 112 , and the anti-vibration plate is connected to the flange portion.
[0061] Among them, there are multiple vents 112. While meeting the supporting strength of the vertical plate 110, by opening multiple vents 112, the outdoor fan 2 can take out the heat of the condenser 3, reduce the obstruction of the vertical plate 110 to the wind, and facilitate the outdoor fan 2 to drive the flow of wind.
[0062] The vents 112 are all surrounded by flanges, which are integrally formed with the mounting riser 110. The flanges are provided to improve the support strength of the vents 112 of the mounting riser 110. The anti-vibration plate is connected to the flange of one of the vents 112.
[0063] In some embodiments, reference Figure 2The frame 100 further includes a positioning plate 140, which is disposed on the top of the mounting riser 110 and on a side away from the first connecting plate 120, and the positioning plate 140 is used to connect to the condenser 3 of the air conditioner outdoor unit.
[0064] When installing the frame 100, the positioning plate 140 abuts against the condenser 3 of the air conditioner outdoor unit to limit the position of the top of the frame 100, and the second connecting plate 130 is plugged into the positioning column to achieve the positioning and fixation of the bottom of the frame 100, thereby making the installation of the frame 100 more convenient.
[0065] In some embodiments, reference Figure 2 and Figure 6 The positioning plate 140 is bent to form a connecting groove, which is used to be mounted on the top of the cold shower of the air conditioner outdoor unit and abut against the side wall of the condenser 3.
[0066] Specifically, the positioning plate 140 includes a support portion 141 and a mounting portion 142. The mounting portion 142 is arranged in a groove shape. The support portion 141 is connected to one side of the mounting portion 142 and is connected to the supporting vertical plate. The mounting portion 142 is bent to form a connecting groove, and the mounting portion 142 mounts the top of the cold shower, thereby realizing the positioning of the top of the supporting vertical plate.
[0067] Therefore, there is no need to use bolts to fix the positioning plate 140 on the condenser 3, which further facilitates the installation of the frame 100 and avoids drilling holes on the condenser 3, thereby reducing damage to the condenser 3.
[0068] In some embodiments, a plurality of reinforcing ribs are disposed on the first connecting plate 120 , the second connecting plate 130 , and the positioning plate 140 .
[0069] The provision of the reinforcing ribs is beneficial to improving the strength of the first connecting plate 120 , the second connecting plate 130 and the positioning plate 140 , so as to facilitate the support of the outdoor fan 2 .
[0070] On the other hand, the present application provides an air conditioner outdoor unit, comprising an air conditioner outdoor unit body 1, an outdoor fan 2, a condenser 3 and a fan bracket arranged in the air conditioner outdoor unit body 1, the outdoor fan 2 is mounted on the fan bracket, and the cold shower is arranged in the air conditioner outdoor unit body 1. The air conditioner outdoor unit body 1, the outdoor fan 2 and the condenser 3 are prior arts and are not described in detail herein.
[0071] Among them, the fan bracket in this embodiment has the same structure as the fan bracket provided in any of the above embodiments, and can bring the same or similar technical effects, which will not be described one by one here, and the details can be referred to the description of the above embodiments.
[0072] The air-conditioning outdoor unit provided in the present application is provided with an anti-vibration member 200 on the frame 100, and the anti-vibration member 200 is in contact with the condenser 3 of the air-conditioning outdoor unit, and the outdoor fan 2 is installed on the mounting hole 111 of the frame 100; thereby, the anti-vibration member 200 supports the frame 100, and the lateral support of the anti-vibration member 200 changes the stress condition of the frame 100, and at the same time, changes the local stiffness of the frame 100 to change the natural frequency of the frame 100, thereby eliminating the resonance between the outdoor fan 2 and the frame 100 and reducing the noise of the air-conditioning outdoor unit.
