Description

Technical Field

[0001] The utility model relates to the technical field of pipeline machines, in particular to an air outlet flange component of a pipeline machine and the pipeline machine. Background Art

[0002] Central air conditioning systems are now widely used in shopping malls, hospitals, office buildings, hotels, and residences. These systems typically use ducted units (also known as ducted air conditioners or ducted air conditioners) to deliver processed, cooled or heated air to each room, regulating the air temperature. Ducted units are also manufactured, sold, and used as standalone units, for example, to regulate the air temperature in relatively small indoor spaces.

[0003] Pipeline air conditioners are usually connected to pipelines using flange structures. Since the air transported by the pipeline air conditioner is cold or hot air, in order to avoid changes in air temperature, it is necessary to add an insulation structure to the flange structure. The current practice is usually to add insulation material to the outside of the flange structure. However, due to the irregular external shape of the flange structure, the insulation material has poor coverage effect, and it is often impossible to completely cover the flange structure, which leads to poor insulation effect. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies in the prior art and to provide an air outlet flange assembly for a ducted air conditioner and a ducted air conditioner.

[0032] See also Figure 1 An embodiment of the present invention provides an air outlet flange assembly for a ducted air conditioner, comprising: a support flange 10 and an insulation flange 20.

[0033] See also Figure 2 and Figure 3 The side of the support flange 10 is provided with a plurality of flange connection parts 11. The support flange 10 is formed with a mounting cavity and a plurality of first air outlets 12 connected to the mounting cavity. The first air outlets 12 are arranged on the flange connection part 11. The thermal insulation flange 20 is formed with an air inlet 21, a plurality of air guide spaces 22 and a plurality of second air outlets 23. The air guide spaces 22 are respectively connected to the second air outlets 23 and the air inlet 21, and the second air outlets 23 are connected to the first air outlets 12. The utility model places the thermal insulation flange 20 inside, so that the air flow circulates inside the thermal insulation flange 20, so that the coverage rate of the thermal insulation flange 20 on the air flow path is high, so that the thermal insulation flange 20 can achieve a better thermal insulation effect. In addition, the thermal insulation structure is usually of low strength. The support of the support flange 10 on the outside of the thermal insulation flange 20 can better improve the stability of the thermal insulation flange 20 structure.

[0034] The number of second air outlets 23 can be designed according to actual needs. For example, in some optional embodiments, at least two first air outlets 12 are formed on the support flange 10, and at least two second air outlets 23 and at least two air guide spaces 22 are formed on the thermal insulation flange 20. The second air outlets 23 are correspondingly connected to the first air outlets 12, and the air guide spaces 22 are correspondingly connected to the second air outlets 23. The air guide spaces 22 can guide the airflow passing through the air inlet 21 into the corresponding second air outlets 23, making the airflow smoother and helping to reduce turbulence.

[0035] To facilitate the division of the air guide spaces 22 and the flow of air, in some optional embodiments, a plurality of partitioning connections 24 are provided inside the thermal insulation flange 20. The partitioning connections 24 divide the interior of the thermal insulation flange 20 into at least two air guide spaces 22. The partitioning connections 24 separate the air guide spaces 22 and can also guide the airflow entering the thermal insulation flange 20 into the air guide space 22 adjacent to the partitioning connections 24. A distribution space 25 is formed between the partitioning connections 24 and the air inlet 21. Adjacent air guide spaces 22 are connected through the distribution space 25. After passing through the air inlet 21, the airflow will enter each air guide space 22, while the airflow of the adjacent air guide space 22 can flow through the distribution space 25, which is conducive to balancing the air pressure of each air guide space 22.

[0036] In some optional embodiments, the air guide space 22 is provided with a plurality of air guides 26 located around the second air outlet 23. The air guides 26 extend gradually and obliquely toward the second air outlet 23 from the air inlet 21. The air guides 26 are used to guide the airflow entering the air guide space 22 toward the second air outlet 23, thereby facilitating airflow and increasing air pressure, thereby, to a certain extent, helping to improve the heat exchange efficiency of the air conditioner connected to the ducted air conditioner. In this embodiment, four air guides 26 are provided around the second air outlet 23.

[0037] In some optional embodiments, the support flange 10 is a resin support flange 10 , and the thermal insulation flange 20 is a foam thermal insulation flange 20 .

[0038] In some optional embodiments, a plurality of bosses 27 are provided on the side of the insulation flange 20, and the second air outlet 23 is provided on the bosses 27. The bosses 27 extend into the interior of the flange connection part 11 and are interference fit with the flange connection part 11, so that the structure of the insulation flange 20 located near the second air outlet 23 is relatively stable and not prone to vibration relative to the supporting flange 10, which is beneficial to improving the structural stability and the sealing between the supporting flange 10 and the insulation flange 20.

[0039] An assembly portion 28 is also provided on the insulation flange 20. The assembly portion 28 is arranged around the air inlet 21. The assembly portion 28 has an interference fit or a zero-zero fit with the inner wall of the installation cavity. The zero-zero fit means that the assembly portion 28 just abuts against the inner wall of the installation cavity, thereby helping to improve the structural stability and the sealing between the support flange 10 and the insulation flange 20.

[0040] A gap is formed between the portion of the thermal insulation flange 20 located between the assembly portion 28 and the boss portion 27 and the inner wall of the installation cavity, thereby achieving a clearance fit between the portion of the thermal insulation flange 20 located between the assembly portion 28 and the boss portion 27 and the installation cavity. Because a certain gap is retained, the air within the gap effectively acts as a layer of thermal insulation, making it more difficult for heat to be transferred between the thermal insulation flange 20 and the support flange 10, which further improves the thermal insulation effect. Furthermore, due to the design of the boss portion 27 and the assembly portion 28, the gap is highly sealed, and the air within the gap does not flow and carry away heat.

[0041] During installation, the insulation flange 20 extends into the installation cavity from the side of the installation cavity away from the first air outlet 12, and then extends into the interior of the flange connection part 11 until the boss part 27 extends into the interior of the flange connection part 11, so that the first air outlet 12 is connected to the second air outlet 23. Usually, when the installation is completed, the boss part 27 is flush with the end of the flange connection part 11, that is, the second air outlet 23 is just inside the first air outlet 12.

[0042] In addition, the insulation flange 20 and the support flange 10 can be adhered to the support flange 10 through colloid, or a detachable connection can be achieved through a snap structure or a threaded structure. Of course, the insulation flange 20 and the support flange 10 can also be formed as one piece.

[0043] The flange connection part 11 is used to connect to the pipeline structure. In some optional embodiments, at least two anti-detachment ribs 13 are provided on the outside of the flange connection part 11. The at least two anti-detachment ribs 13 are evenly arranged around the flange connection part 11. The anti-detachment ribs 13 can prevent the pipeline structure connected to the flange connection part 11 from falling off. For example, some hose structures are relatively easy to loosen. The anti-detachment ribs 13 can clamp the hose structure and improve the connection stability.

[0044] See also Figure 4 and Figure 5 The above-mentioned air outlet flange assembly of a ducted air conditioner can be applied to a ducted air conditioner, which includes: a body 30 and an air outlet flange assembly of a ducted air conditioner as described above, the body 30 is provided with a third air outlet 31, the support flange 10 is installed on the body 30, the air inlet 21 is connected to the third air outlet 31, and the air flow blown out of the ducted air conditioner enters the air inlet 21 through the third air outlet 31.

[0045] In some optional embodiments, in the projection direction parallel to the air outlet direction of the third air outlet 31, the first air outlet 12 and the second air outlet 23 are located within the projection range of the third air outlet 31, and the total projection area of ​​the second air outlet 23 is smaller than that of the first air outlet 12. This design is conducive to the airflow passing directly through the air inlet 21 and the air guide space 22, and then reaching the second air outlet 23 and the first air outlet 12, which is conducive to the smooth flow of air.

[0046] Since the support flange 10 structure is usually made of a material with higher hardness than the insulation flange 20, in some optional embodiments, part of the insulation flange 20 protrudes from the side of the support flange 10 away from the first air outlet. When the support flange 10 is installed on the main body 30, the insulation flange 20 abuts the main body 30, and an avoidance gap is formed between the part of the support flange 10 located near the air inlet 21 and the main body 30. This design is conducive to reducing the contact between the support flange 10 and the main body 30, thereby reducing the vibration transmitted to the support flange 10, which is conducive to reducing the noise generated by the support flange 10, and also avoids the vibration of the main body 30 and the support flange 10, which causes a larger range of collision between the two, thereby reducing the generation of noise.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
