Description

Technical Field

[0001] The utility model relates to the field of air-conditioning host, in particular to a heat insulation and noise reduction structure of an air-conditioning host. Background Art

[0002] Air conditioners are categorized as either cooling-only or dual-purpose, operating on the same principle. Freon, a refrigerant commonly used in air conditioners, previously released a significant amount of heat when it transitioned from gas to liquid. Furthermore, when it transitioned from liquid to gas, it absorbed a significant amount of heat (i.e., it first absorbed heat, vaporized, and then liquefied, releasing heat). Air conditioners were designed based on this principle. With improvements in living standards, air conditioners are becoming increasingly common. Currently, 80% of homes have air conditioners installed, with the main unit often hung outside the building. Consequently, consumers are increasingly concerned with the performance of the main unit.

[0003] The existing air conditioner main unit has internal electronic control components that generate heat during operation. In addition, the main unit is installed outdoors, which further reduces the heat dissipation effect of the main unit. A fan cavity is provided on one side of the electronic control component area inside the main unit. The fan blades in the fan cavity draw air from the side and then exhaust it to the outside to dissipate heat inside the main unit. However, the air inlet on the outside of the existing main unit is directly exposed to the outside (for details, please refer to Figure 5 ), the filter in the air inlet will accumulate too much dust after long-term use, affecting the heat dissipation effect of the air conditioner host. The filter is also more easily damaged when exposed to the outside. At the same time, the air conditioner host is easily exposed to the sun outdoors, and the host shell has no heat insulation structure. The heat from the sun will directly affect the air conditioner host, resulting in poor heat insulation and heat dissipation performance between the inside and outside of the host. In addition, the rapid rotation of the fan blades in the fan cavity will cause the host to vibrate, thereby generating noise, which will affect the normal use of the user. Therefore, it is particularly important to design a heat insulation and noise reduction structure for the air conditioner host to solve the above defects. Utility Model Content

The downward air guide plate is used to block the external dust first, and then when the fan blades rotate, the air is sucked in from the air inlet, and after entering the air inlet cover, the filter is used to block the dust, thereby preventing the dust in the air from entering the interior of the air conditioner host and affecting the internal electronic control components. At the same time, the air inlet cover can protect the filter to prevent the filter from being directly exposed to the outside of the air conditioner shell. Excessive accumulation of dust affects the heat dissipation effect of the air conditioner host. The air entering the inside of the air conditioner casing passes through the heat dissipation air cavity and then enters the inside of the vent, and is finally discharged through the fan blades, thereby dissipating the heat inside the air conditioner main unit very well. At the same time, when the air circulates outside the air conditioner main unit through the top of the air conditioner main unit, the air enters the inside of the heat sink. The air stays fully inside the heat sink and exchanges heat with the heat inside the heat sink, thereby improving the heat dissipation effect outside the main unit casing. In addition, the sun visor is used to block sunlight to prevent the heat from the sun's exposure from directly acting on the top of the main unit casing, which greatly improves the heat insulation and heat dissipation effect inside and outside the air conditioner main unit.

In the present invention, the first sound insulation board, the second sound insulation board and the shock-absorbing mechanism are designed in coordination, and the first sound insulation board and the second sound insulation board are used to insulate and reduce the noise generated by the rotation and vibration of the fan blades in the inner shell. At the same time, the connection part is moved into the sleeve to buffer and absorb the vibration generated by the rotation of the fan blades in the inner shell through the action of the spring, thereby further reducing the noise generated by the vibration, thereby improving the noise reduction effect of the air conditioner host.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] This embodiment provides a heat-insulating and noise-reducing structure for the air-conditioning host, which can play a good role in heat insulation and heat dissipation when the air-conditioning host is working, while increasing the noise reduction effect and improving the overall practicality of the air-conditioning host.

[0023] See also Figure 1-Figure 4 The heat insulation and noise reduction structure of the air-conditioning host of this embodiment includes a host shell 1. Mounting frames are provided on the left and right sides of the bottom of the host shell 1. A plurality of mounting holes are provided on the top of the mounting frame. The mounting frame and the host shell 1 are designed as an integrated structure. The mounting frame is used to support the host shell 1 and facilitate the installation and fixation of the host shell 1.

[0024] An air inlet cover 2 is provided on both sides of the main housing 1, a heat sink 3 is provided on the top of the main housing 1, and a sun visor 4 is provided on the top of the heat sink 3. An inner shell 5 is provided inside the main housing 1, a first sound insulation board 6 is provided on the inner side wall of the main housing 1, and a second sound insulation board 7 is provided on the outer side wall of the inner shell 5. The first sound insulation board 6 is connected to the second sound insulation board 7 through multiple groups of shock absorbing mechanisms 8. A heat dissipation air cavity 9 is formed inside the main housing 1 and between the first sound insulation board 6 and the second sound insulation board 7. Ventilation holes 10 are provided on the left and right sides of the shell wall of the inner shell 5 and the second sound insulation board 7, and the interior of the inner shell 5 and the interior of the main housing 1 are connected through the ventilation holes 10.

[0025] Specifically, a plurality of groups of sound-absorbing protrusions are provided on the inner side of the first sound insulation board 6, and a plurality of groups of sound-absorbing holes are provided on the outer side of the second sound insulation board 7. The first sound insulation board 6, the second sound insulation board 7 and the sound-absorbing protrusions are all made of polyester fiber material. The noise generated by the vibration when the fan blades rotate is soundproofed and reduced by the first sound insulation board 6 and the second sound insulation board 7.

[0026] The shock absorbing mechanism 8 is composed of a sleeve 14, a connecting column 15 and a spring 16. Multiple groups of sleeves 14 are provided on the inner side of the first sound insulation board 6. The sleeve 14 is connected to the second sound insulation board 7 through the connecting column 15. The connecting column 15 is located inside the sleeve 14 and is provided with a spring 16. The spring 16 is equipped with a damper. The connection between the connecting column 15 and the sleeve 14 is a sliding connection. The vibration generated by the rotation of the fan blade acts on the inner shell 5, and the vibration generated by the inner shell 5 moves into the sleeve 14 through the connecting column 15. The spring 16 is used to buffer and absorb the vibration, thereby reducing the noise generated by the rotation of the fan blade.

[0027] An air inlet is provided on the outside of the air inlet hood 2, and multiple groups of air guide plates are provided inside the air inlet, and the multiple groups of air guide plates are designed in a slanted downward structure. A filter 11 is provided inside the air inlet hood 2, and a dust collection box 12 is slidably connected to the outside of the air inlet hood 2 and located between the filter 11 and the air inlet. A handle is provided on the outside of the ash collection box 12. The air outside the air inlet hood 2 is first blocked by the air guide plate to filter the dust after entering the interior of the air inlet hood 2. The dust accumulated on the filter 11 can be collected by the ash collection box 12 after falling down, and the ash collection box 12 can be pulled out to dump the dust.

[0028] Heat dissipation inclined grooves 13 are provided on the left and right sides of the heat dissipation plate 3, and an air guide groove is provided inside the heat dissipation plate 3 and between the two groups of heat dissipation inclined grooves 13. The air guide groove is designed in a wavy structure. The four corners of the top of the heat dissipation plate 3 are connected to the sun visor 4 through support columns. The edges of the sun visor 4 are all designed in a slanted downward structure. When the external air of the main unit casing 1 circulates, the air stays fully inside the heat dissipation plate 3 through the air guide groove and exchanges heat with the heat inside the heat dissipation plate 3, thereby improving the heat dissipation effect of the outside of the main unit casing 1, and the sun visor 4 is used to block sunlight to prevent the heat from the sun's exposure from directly acting on the top of the main unit casing 1, which greatly improves the heat insulation and heat dissipation effect inside and outside the air-conditioning main unit.

[0029] In this embodiment, the implementation scenario is specifically as follows: the inner shell 5 is used to accommodate the fan blades, electronic control components, etc. of the air-conditioning main unit. After the air enters the inner shell 5 by rotating the fan blades to suck air, the heat generated by the electronic control components is discharged, thereby dissipating the heat inside the air-conditioning main unit.

[0030] When the air conditioner is working, the rotation of the fan blades inside the inner shell 5 allows air to enter the inside of the air inlet cover 2 from the outside of the air inlet cover 2, and the air inlet cover 2 is used to filter dust in the air to prevent dust from entering the inside of the air conditioner and affecting the internal electronic control components. At the same time, the air inlet cover 2 is used to protect the filter 11 to prevent excessive accumulation of dust from affecting the heat dissipation effect. The air entering the inside of the main shell 1 passes through the heat dissipation air cavity 9 and then enters the inside of the vent 10, and is finally discharged through the fan blades, thereby dissipating the heat well for the inside of the air conditioner. At the same time, when the air circulates outside the air conditioner through the top of the air conditioner, the air enters the inside of the heat sink 3, and the air fully stays inside the heat sink 3 and between the heat sink 3 and the heat sink 3. The internal heat is heat exchanged, thereby improving the heat dissipation effect of the outside of the main unit casing 1, and the sun visor 4 is used to block sunlight to prevent the heat from the sun's exposure from directly acting on the top of the main unit casing 1, greatly improving the heat insulation and heat dissipation effect inside and outside the air-conditioning host. When the air-conditioning host is working, the first sound insulation board 6 and the second sound insulation board 7 can well soundproof and reduce the noise generated by the rotation and vibration of the fan blades. At the same time, the shock absorbing mechanism 8 is used to buffer and absorb the vibration generated by the rotation of the fan blades, further reducing the noise generated by the vibration, thereby improving the noise reduction effect of the air-conditioning host. The entire operation process is simple and convenient. Compared with the existing air-conditioning host, the utility model can improve the overall heat insulation and heat dissipation, noise reduction and practicality of the host through design.
