Description

Technical Field

[0001] The invention relates to the field of air conditioners, and in particular to a heat dissipation, vibration reduction and power saving structure of an air conditioner outdoor unit and an air conditioner. Background Art

[0002] Air conditioners are divided into cooling-only air conditioners and dual-purpose air conditioners. Their working principles are the same. In the past, most air conditioners generally used Freon as a refrigerant. The characteristic of Freon is that when it changes from gas to liquid, it releases a lot of heat. When it changes from liquid to gas, it absorbs a lot of heat (i.e., it absorbs heat first and then liquefies and releases heat). Air conditioners are designed based on this principle. With the improvement of people's living standards, air conditioners are used more and more widely. Currently, 80% of households have air conditioners installed. In addition, in new communities, most air conditioners have their outdoor units placed in isolated places indoors. The outdoor units of air conditioners cannot be hung on the outside of the floor. Therefore, consumers pay more and more attention to the performance of the outdoor units of air conditioners.

[0003] In the prior art, during the operation of the outdoor unit, on the one hand, the motor shaft drives the axial fan blades to rotate rapidly, which will cause the motor bracket to vibrate and generate noise. When the motor bracket vibrates too much, it may even cause abnormal noise, which may easily lead to after-sales complaints. On the other hand, the outdoor unit's electronic control box needs to be waterproof, so the structure is closed, but this is not conducive to heat dissipation, which may easily lead to excessive temperature rise and cause a fire. Summary of the invention

[0004] In view of this, the present invention aims to provide an air conditioner outdoor unit heat dissipation, shock absorption and power saving structure and an air conditioner to solve the problem that the existing air conditioner outdoor unit motor bracket vibrates and generates noise, and the outdoor unit electric control box structure is closed, which is not conducive to heat dissipation.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A heat dissipation, shock absorption and power saving structure for an air conditioner outdoor unit comprises a motor support, a wind shielding plate, an electric control box and an axial flow fan blade. A heat dissipation and shock absorption structure is arranged between the wind shielding plate and the motor support. Two ends of the heat dissipation and shock absorption structure are respectively connected to the wind shielding plate and the motor support, which can improve the connection strength between the wind shielding plate and the motor support.

[0007] The heat dissipation and shock absorption structure connects the wind-shielding vertical plate and the motor bracket together, which can greatly limit the vibration of the motor bracket and effectively improve the shock absorption effect of the motor bracket.

[0008] Furthermore, the heat dissipation and shock absorption structure includes a heat dissipation part and a shock absorption part, wherein two ends of the shock absorption part are respectively connected to the wind shielding vertical plate and the motor bracket, and the heat dissipation part transmits the wind force generated by the rotation of the axial flow fan blade to the electronic control box.

[0009] The damping part is used to dampen the vibration of the motor bracket, and the wind force generated by the rotation of the axial flow fan blades is transmitted to the electric control box through the heat dissipation part to dissipate the heat of the electric control box, which can effectively prevent the electric control box from exceeding the temperature limit due to improper heat dissipation, thereby causing a fire.

[0010] Furthermore, the shock absorbing part includes a connecting rod, and a first panel and a second panel are respectively provided at both ends of the connecting rod. The first panel is detachably connected to the motor bracket, and the second panel is detachably connected to the wind-shielding vertical plate.

[0011] The heat dissipation and shock absorption structure is connected to the motor bracket and the wind-shielding vertical plate in a detachable manner, so that the heat dissipation and shock absorption structure can be easily replaced.

[0012] Furthermore, a connection hole is formed on the second panel, and the connection hole is used to fix the heat dissipation part.

[0013] By fixing the heat dissipation part in the connection hole, the heat dissipation part and the shock absorbing part are connected as one, which is convenient for the overall installation and removal of the heat dissipation part and the shock absorbing part.

[0014] Furthermore, the wind-shielding vertical plate is provided with a ventilation hole near the electric control box, and the heat dissipation portion extends from the ventilation hole toward a direction close to the axial flow fan blade.

[0015] A wind channel is formed between the axial flow fan blades and the electric control box, and the heat dissipation unit transmits wind from the axial flow fan blades to the electric control box to dissipate heat for the electric control box, thereby preventing the electric control box from being damaged due to excessive temperature.

[0016] Furthermore, the heat dissipation portion is a hollow structure.

[0017] The wind force generated by the axial flow fan blades can flow through the inside of the heat dissipation part.

[0018] Furthermore, the heat dissipation portion is arranged above the axial flow fan blade near one end of the axial flow fan blade.

[0019] The static pressure of the gas above the heat dissipation part close to the axial flow fan blade is relatively large, and the static pressure on the other side of the heat dissipation part is relatively small. The air will flow from the high pressure side to the low pressure side, and the wind force generated by the axial flow fan blade will be directed to the electronic control box.

[0020] Furthermore, a water retaining ring is arranged on the inner wall of the heat dissipation part.

[0021] When the air conditioner outdoor unit is running, condensation water will be generated inside the air conditioner outdoor unit. The axial flow fan blades will blow the condensation water to move when rotating. The water retaining ring can block the condensation water to prevent the condensation water blown into the heat dissipation part from entering the electric control box along the heat dissipation part.

[0022] Furthermore, the second panel is provided with small axial flow fan blades, and the small axial flow fan blades are fixed on the second panel.

[0023] When the wind in the heat dissipation part passes through the second panel, the small axial flow fan blades are driven to rotate, and the small axial flow fan blades expand the wind rotation area, that is, increase the heat dissipation area of ​​the electric control box.

[0024] Furthermore, a power generation device is provided in the electric control box, and the power generation device is connected to the small axial flow fan blades through a wire, and the rotation of the small axial flow fan blades drives the power generation device to generate electricity.

[0025] The power generation device converts the kinetic energy of the small axial flow fan blades when they rotate into electrical energy. The power generation device can directly supply power to the electric control box, thereby saving electricity consumption of the air conditioner.

[0026] Furthermore, an air conditioner includes the above-mentioned heat dissipation, vibration reduction and power saving structure of the air conditioner outdoor unit.

[0027] Compared with the prior art, the heat dissipation, shock absorption and power saving structure of the air conditioner outdoor unit and the air conditioner described in the present invention have the following advantages: by arranging a connecting rod between the motor bracket and the wind shielding plate, the vibration of the motor bracket can be greatly limited; by adding a heat dissipation section, the electric control box can be cooled to prevent the electric control box from causing a fire due to excessive temperature; through the rotation of the small axial flow blades, the power generation device is driven to generate electricity to supply power to the electric control box, thereby saving electricity for the air conditioner.

[0040] 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.

[0041] Embodiment 1:

[0042] See attached Figure 1 A heat dissipation, shock absorption and power saving structure of an air conditioner outdoor unit includes a motor bracket 1, a wind shielding plate 2, an electric control box 3, and an axial flow fan blade 5. A heat dissipation and shock absorption structure 4 is arranged between the wind shielding plate 2 and the motor bracket 1. The two ends of the heat dissipation and shock absorption structure 4 are respectively connected to the wind shielding plate 2 and the motor bracket 1, which can improve the connection strength between the wind shielding plate 2 and the motor bracket 1.

[0043] Specifically, the wind-blocking plate 2 divides the internal space of the air-conditioning outdoor unit into two parts, one part of which is installed with a motor bracket 1, and the axial-flow fan blades 5 are installed above the motor bracket 1; the other part of the space is installed with an electric control box 3, and a heat dissipation and shock-absorbing structure 4 is installed between the wind-blocking plate 2 and the motor bracket 1. After the heat-dissipation and shock-absorbing structure 4 connects the wind-blocking plate 2 with the motor bracket 1, it can limit the vibration of the motor bracket 1 and provide a better shock-absorbing effect for the air-conditioning outdoor unit.

[0044] Since the shock absorbing part 401 connects the wind-shielding vertical plate 2 and the motor bracket 1 together, when the axial-flow fan blades 5 rotate and generate vibrations, the local rotation of the axial-flow fan blades 5 is converted into the overall vibration of the air-conditioning outdoor unit, which greatly limits the vibration of the motor bracket 1.

[0045] In some embodiments of the present invention, see the attached Figure 2 The heat dissipation and shock absorption structure 4 includes a heat dissipation part 402 and a shock absorption part 401, wherein the two ends of the shock absorption part 401 are respectively connected to the wind-shielding vertical plate 2 and the motor bracket 1, the heat dissipation part 402 transmits the wind force generated by the rotation of the axial flow fan blades 5 to the electric control box 3, and the shock absorption part 401 is used to dampen the shock of the motor bracket 1. At the same time, the wind force generated by the axial flow fan blades 5 is dissipated to the electric control box 3 through the heat dissipation part 402, so as to prevent the electric control box 3 from exceeding the temperature rise standard due to improper heat dissipation and causing a fire.

[0046] In some embodiments of the present invention, the specific structure of the shock absorbing part 401 is as follows: Figure 7 The shock absorbing part 401 includes a connecting rod 404, and the two ends of the connecting rod 404 are respectively provided with a first panel 403 and a second panel 405, the first panel 403 is detachably connected to the motor bracket 1, and the second panel 405 is detachably connected to the wind-shielding upright plate 2, and the connecting rod 404 is arranged in an inclined shape to connect the wind-shielding upright plate 2 with the motor bracket 1. When the motor bracket 1 vibrates, the vibration of the motor bracket 1 is limited by the connecting rod 404 and the wind-shielding upright plate 2, thereby providing a better shock-absorbing effect for the operation of the air-conditioning outdoor unit. Preferably, the connecting rod 404 is a plate-like structure, and the heat dissipation and shock-absorbing structure 4 is detachably connected to the motor bracket 1 and the wind-shielding upright plate 2, respectively, so that it is easy to disassemble when the motor bracket 1, the wind-shielding upright plate 2 or the heat dissipation and shock-absorbing structure 4 needs to be replaced. Preferably, see the attached Figure 2 , Attachment Figure 5 With attached Figure 6 The first panel 403 is provided with two bolt holes, and the second panel 405 is provided with four bolt holes. The first panel 403 is fixed to the motor bracket 1 by bolts, and the second panel 405 is fixed to the wind-shielding vertical plate 2 by bolts.

[0047] In some embodiments of the present invention, see the attached Figure 7 A connecting hole 406 is opened on the second panel 405, and the connecting hole 406 fixes the heat dissipation part 402. The heat dissipation part 402 is connected to the shock absorbing part 401 through the second panel 405. When the shock absorbing heat dissipation structure needs to be replaced, the shock absorbing heat dissipation structure can be disassembled as a whole.

[0048] In some embodiments of the present invention, see the attached Figure 3-4The wind-shielding vertical plate 2 has a ventilation hole near the electric control box 3, and the heat dissipation portion 402 extends from the ventilation hole toward the axial flow fan blade 5. The wind force generated by the rotation of the axial flow fan blade 5 is transmitted through the heat dissipation portion 402, and finally the wind force passes through the heat dissipation portion 402 and blows toward the electric control box 3 to dissipate the heat of the electric control box 3.

[0049] In some embodiments of the present invention, the specific structure of the heat dissipation unit 402 is as follows: Figure 8 The heat dissipation part 402 is a hollow structure. When the axial flow fan blade 5 rotates to generate wind force, the wind force flows through the hollow structure of the heat dissipation part 402 toward the wind-blocking vertical plate 2, and finally flows to the electric control box 3 to cool the electric control box 3. The electric control box 3 is cooled by internal wind force. The electric control box 3 is cooled by internal wind force. The structure is simple and energy saving. Preferably, the heat dissipation part 402 is a tubular structure. The outer contour of the heat dissipation part 402 can be a straight line trajectory or a curved trajectory. The more complex the outer contour trajectory of the heat dissipation part 402 is, the better the waterproof effect is. Preferably, see the attached Fig. 9 , the outer contour trajectory of the heat dissipation portion 402 is a straight line trajectory.

[0050] In some embodiments of the present invention, see the attached Figure 1 The heat dissipation portion 402 is arranged above the axial flow fan blade 5 at one end close to the axial flow fan blade 5. The static pressure of the gas above the heat dissipation portion 402 close to the axial flow fan blade 5 is relatively large, and the static pressure on the other side of the heat dissipation portion 402 is relatively small. The air will flow from the high-pressure side to the low-pressure side, and when the axial flow fan blade 5 rotates, wind will blow directly into the tube, and air will also enter along the tube, guiding the wind force generated by the axial flow fan blade 5, guiding the wind force into the heat dissipation portion 402, and flowing out through the heat dissipation portion 402.

[0051] See attached Figure 8 A water retaining ring 409 is arranged on the inner wall of the heat dissipation part 402. The shape of the water retaining ring 409 is the same as the outer contour shape of the heat dissipation part 402, and a circular hole is opened in the middle. When the air conditioner outdoor unit is running, condensed water will be generated inside the air conditioner outdoor unit. The axial flow fan blade 5 will blow the condensed water to move when rotating. The water retaining ring 409 can block the condensed water to prevent the condensed water blown into the heat dissipation part 402 from entering the electric control box 3 along the heat dissipation part 402, causing the internal circuit of the electric control box 3 to short-circuit and damage the air conditioner outdoor unit. The number of the water retaining rings 409 is set according to the actual situation. When used in a relatively humid area, a plurality of the water retaining rings 409 can be set to make the heat dissipation section have a better water retaining effect. When used in a dry area, only one water retaining ring 409 can be set.

[0052] In some embodiments of the present invention, see the attached Figure 7 A small axial flow fan blade 407 is provided on the second panel 405. The small axial flow fan blade 407 is fixed on the second panel 405. The small axial flow fan blade 407 diffuses the wind force conducted by the heat dissipation part 402, increases the heat dissipation area blowing toward the electric control box 3, and can better dissipate the heat of the electric control box 3.

[0053] Embodiment 2:

[0054] See attached Figure 3 A heat dissipation, shock absorption and power saving structure of an air conditioner outdoor unit, comprising a motor bracket 1, a wind shielding plate 2, an electric control box 3 and an axial flow fan blade 5.

The two ends of the heat dissipation and shock absorption structure 4 are respectively connected to the wind shielding plate 2 and the motor bracket 1, which can improve the connection strength between the wind shielding plate 2 and the motor bracket 1. A power generation device 6 is arranged in the electric control box 3. The power generation device 6 generates electricity by using the wind power transmitted by the heat dissipation and shock absorption structure 4, and supplies power to the electric control box 3.

[0055] The heat dissipation and shock absorption structure 4 includes a heat dissipation part 402 and a shock absorption part 401, and the shock absorption part 401 includes a connecting rod 404, and the two ends of the connecting rod 404 are respectively provided with a first panel 403 and a second panel 405, and the second panel 405 is provided with a small axial flow fan blade 407, and the small axial flow fan blade 407 is fixed on the second panel 405. The power generation device 6 is connected to the small axial flow fan blade 407 through a wire, and the small axial flow fan blade 407 rotates to drive the power generation device 6 to generate electricity, and the axial flow fan blade 5 rotates to generate wind power, and the wind The force is transmitted to the electric control box 3 through the heat dissipation part 402. When the wind passes through the heat dissipation part 402, the small axial flow blades 407 are driven to rotate. The power generation device 6 converts the kinetic energy of the rotation of the small axial flow blades 407 into electrical energy. The power generation device 6 supplies the generated electrical energy to the electric control box 3. The wind force generated by the axial flow fan blades 5 is used to generate electricity and supply power to the electric control box 3, which can effectively save electricity for air conditioning. At the same time, the heat dissipation and shock absorption structure 4 can reduce the vibration of the motor bracket 1 and dissipate the heat of the electric control box 3.
