Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, specifically to an airflow control structure and air conditioning equipment. Background Technology

[0002] Currently, with people's increasing demands for work and quality of life, air conditioning equipment has been widely used in various places. By configuring different air conditioning components, different air conditioning functions can be achieved. For example, configuring air cooling components can generate cold air to achieve a cooling effect; configuring air heating components can generate hot air to achieve a heating effect; configuring air filtration components, air disinfection components, and air humidity control components can achieve air sterilization, dust removal, and humidity control, thereby improving air quality.

[0003] To maximize the air conditioning effect of the equipment, air outlet ducts are installed instead of conventional air vents. These ducts concentrate the airflow from the equipment into a specific direction and angle, delivering it to the designated location at a certain distance, thus improving the user experience. To meet the needs of different locations, two or more pairs of air outlet ducts can be used. By individually setting the direction and angle of each duct, the resulting airflow can be simultaneously delivered to its corresponding location. However, increasing the number of air outlet ducts to two or more can lead to inconsistent airflow strength, making it difficult to provide continuous and stable airflow to each location. Furthermore, the airflow rate of each individual air outlet duct is reduced, affecting the airflow delivery distance. Utility Model Content

[0004] This application provides an airflow control structure and an air conditioning device, which are intended to at least improve the technical problems existing in the prior art.

[0005] In accordance with the above objectives, this application provides an airflow control structure for use in air conditioning equipment, comprising: At least two air outlet ducts are provided on the air conditioning equipment, and the air outlet ducts include a first end that is connected to the air conditioning equipment; The air chamber has a first chamber, at least two first air outlets are provided on one side of the first chamber, and one of the first air outlets is connected to the first end of an air outlet pipe; a first air inlet is provided on the other side of the first chamber, and the first air inlet is connected to the fan of the air conditioning equipment. The first chamber has a first height from the first air outlet to the first air inlet. The fan of the air conditioning equipment operates to send out air, which is then sent into the first chamber through the first air inlet, and then forms at least two airflows through the first ends of the at least two first air outlets and at least two air outlet pipes.

[0006] This application has the following beneficial effects: The first chamber inside the air chamber receives the airflow sent by the fan and buffers and balances it in the first chamber. Then, it is distributed to each air outlet pipe through the first air outlet and the first end of the air outlet pipe. This avoids the airflow of the fan directly entering each air outlet pipe. Instead, it sends the uniform air filling the first chamber into each air outlet pipe, thereby realizing the formation of a uniform and stable airflow in each air outlet pipe and sending it out. This ensures that each usage position can continuously obtain stable air supply and improves the uniformity and reliability of multi-pipe air supply in air conditioning equipment.

[0007] Furthermore, the air chamber is also provided with a second chamber, which is divided into at least two booster fans. Each booster fan corresponds to the air outlet pipe and the first air outlet. The air inlet of the booster fan is directly opposite the first air outlet, and the air outlet of the booster fan is connected to the first end of the air outlet pipe.

[0008] Furthermore, the first air inlet and the first air outlet are respectively located on the two side walls of the opposite first chamber.

[0009] Furthermore, the first height is 5-15cm.

[0010] Furthermore, a nozzle is inserted into the second end of the air outlet pipe, and the outer diameter of the nozzle is smaller than the inner diameter of the second end of the air outlet pipe.

[0011] Furthermore, the air nozzle includes a pressure boosting section and a flow guiding section. The pressure boosting section gradually narrows its inner diameter in a direction away from the second end of the air outlet pipe and is connected to the flow guiding section. The inner diameter of the flow guiding section is the same.

[0012] Furthermore, a collar is provided around the flow guide, the collar being integrally extended from the outer wall of the pressurizing part, and a reinforcing rib is provided between the collar and the flow guide.

[0013] Furthermore, the end of the collar is provided with an outer folding ring, the inner diameter of which is adapted to the outer diameter of the second end of the air outlet pipe, so as to fix and seal the outer folding ring to the second end of the air outlet pipe after the air nozzle is inserted into the second end of the air outlet pipe.

[0014] This application also provides an air conditioning device, including a body and an airflow control structure as described above, wherein a fan and an air conditioning component are provided inside the body.

[0024] Air conditioning equipment typically uses only one fan to output regulated air, and the fan also has only one air outlet. However, in air conditioning equipment with two or more air outlet ducts, the air inlets of the two or more air outlet ducts and the air outlets of the fan cannot be aligned one-to-one, resulting in positional differences. This causes the single airflow output from the air outlet to enter each air outlet duct and form multiple airflows. The uniformity of these airflows is affected by the position of the corresponding air outlet duct's air inlet, with the airflow in the air outlet duct closer to the air outlet being greater than that in the air outlet duct farther from the air outlet.

[0025] To solve the above problems, see attached Figure 1-5 As shown, this application provides an airflow control structure for use in air conditioning equipment through the following technical solution, including: Air outlet duct 1 is installed on the air conditioning equipment. The first end of air outlet duct 1 is connected to the air conditioning equipment. Air outlet duct 1 has at least two outlet ducts. Air chamber 2 is located between the fan 41 and the air outlet duct 1 of the air conditioning equipment. Air chamber 2 has a closed first chamber 21. A first air outlet 22 is provided on one side of the first chamber 21. The first air outlet 22 is connected to the first end of the air outlet duct 1. The number of first air outlets 22 is the same as the number of air outlet ducts 1, and there are at least two. A first air inlet 23 is provided on the other side of the first chamber 21. The first air inlet 23 is connected to the fan 41 of the air conditioning equipment. The first chamber 21 between the first air outlet 22 and the first air inlet 23 has a first height. The fan 41 of the air conditioning equipment works to send out air, which is sent into the first chamber 21 through the first air inlet 23, and then through at least two first air outlets 22 and the first ends of at least two air outlet pipes 1 to form at least two airflows.

[0026] Compared with the prior art, this application has the following beneficial effects: the first chamber inside the air chamber receives the airflow sent by the fan and buffers and balances it in the first chamber, and then distributes it to each air outlet pipe through the first air outlet and the first end of the air outlet pipe. This avoids the airflow of the fan directly entering each air outlet pipe, but instead sends the uniform air filling the first chamber into each air outlet pipe, thereby realizing the formation of a uniform and stable airflow in each air outlet pipe and sending it out, so that each usage position can continuously obtain a stable air supply, and improve the uniformity and reliability of multi-pipe air supply of the air conditioning equipment.

[0027] In the technical solution applied in this embodiment, the air outlet of the air conditioning equipment is generated by the fan 41. The fan 41 produces a single stream of air with a certain pressure and velocity to achieve the output of the air conditioning equipment after air conditioning. The enclosed first chamber 21 within the air chamber 2 has a larger space than the first air inlet 23 due to its height. After the air flow generated by the fan 41 enters the first chamber 21 through the first air inlet 23, the pressure of the airflow generated by the fan 41 is released and quickly fills the entire first chamber 21 in the larger chamber space. The air pressure in the first chamber 21 quickly equalizes, achieving buffering and balancing of the air flow delivered by the fan 41. In this way, the air in the first chamber 21 can be evenly entered into the air outlet 1 through the first air outlet 22 and the first end of the air outlet 1 under the action of balanced pressure, forming a uniform airflow in each air outlet 1 and being delivered.

[0028] It should be noted that the number of air outlet pipes 1 can be set to two or more depending on the usage requirements. In the embodiment of this application, the number of air outlet pipes 1 is two.

[0029] Specifically, the space of the first chamber 21 can be rectangular, square, or regular polygonal, preferably rectangular. The first air outlet 22 and the first air inlet 23 are respectively located on the two side walls of the opposite first chamber 21. The first height of the first chamber 21 between the first air outlet 22 and the first air inlet 23 provides a buffer and balancing chamber space for the air outlet of the fan 41. The first height can be adjusted within different ranges. When the air outlet of the fan 41 is small or the number of air outlet pipes 1 is large, the smaller chamber space provided by the lower first height ensures that the pressure is not too low when the airflow fills the first chamber 21. When the air outlet of the fan 41 is large or the number of air outlet pipes 1 is small, the higher first height provides a relatively larger chamber space, ensuring that the pressure is not too high when the airflow fills the first chamber 21. Maintaining an appropriate pressure when the airflow fills the first chamber 21 can better achieve uniform and stable airflow into each air outlet pipe 1. The first height is preferably 5-15cm.

[0030] In the technical solution applied in this embodiment, the first air outlet 22 and the first air inlet 23 are respectively located on the two side walls of the opposite first chamber 21. In this way, after the airflow generated by the fan 41 enters the first chamber 21 through the first air inlet 23, it can continue to enter the first air outlet 22 in the original flow direction, avoiding turbulence caused by a large change in flow direction, which would lead to uneven airflow pressure and affect the uniformity of subsequent airflow into the air outlet duct 1.

[0031] Furthermore, the air conditioning equipment typically has only one fan 41, and its corresponding first air inlet 23 is also only one; while the number of air outlet ducts 1 is at least two, and the corresponding number of first air outlets 22 is also at least two. The difference in the number of first air outlets 22 and first air inlets 23 means that they cannot be aligned with each other, resulting in a difference in the relative position of different first air outlets 22 relative to the first air inlets 23. The airflow velocity of the fan 41 will change slightly when it enters the first chamber 21 and passes through the first air outlets 22 at different positions. The airflow velocity is higher at the first air outlets near the first air inlet 23 and lower at the first air outlets far from the first air inlet 23. This difference in velocity will also affect the uniformity of the airflow entering the air outlet duct 1. Therefore, the size of the first air outlets 22 at different positions can be appropriately adjusted, that is, the opening of the first air outlet 22 near the first air inlet 23 is smaller, and the opening of the first air outlet 22 far from the first air inlet 23 is larger, in order to overcome the influence of the velocity difference on the uniformity of the airflow entering the first air outlet 22.

[0032] The design of the air chamber 2 solves the problem of uniform airflow entering the two outlet pipes 1, but at the same time, the air chamber 2 also reduces the pressure and velocity of the airflow entering the outlet pipe 1. Therefore, a second chamber 25 is also provided within the air chamber 2, and a booster fan 24 is installed in the second chamber 25. The number of booster fans 24 is the same as that of the outlet pipes 1, and they are arranged one-to-one with the outlet pipes 1 and the first air outlet 22. Different booster fans 24 are separated from each other, with the air inlet of the booster fan 24 facing the corresponding first air outlet 22, and the air outlet of the booster fan 24 connected to the first end of the corresponding outlet pipe 1. After the airflow in the first chamber 21 enters through the first air outlet 22, it enters the air inlet under the action of the booster fan 24 for secondary pressurization. The pressurized airflow then enters the outlet pipe 1 through the first end of the outlet pipe 1, increasing both the pressure and velocity of the airflow formed in the outlet pipe 1, thus allowing the airflow to reach a longer delivery distance after being delivered. Since the booster fans 24 are of the same specifications and are set separately, and are located in the second chamber 25, they will not affect the uniformity of the airflow entering the outlet duct 1.

[0033] Furthermore, in order to further increase the airflow delivery distance of the air outlet duct 1, a nozzle 3 is provided at the second end of the air outlet duct 1. The outer diameter of the nozzle 3 is smaller than the inner diameter of the second end of the air outlet duct 1, and the nozzle 3 is inserted into the second end of the air outlet duct 1.

[0034] Specifically, the nozzle 3 includes a pressurizing section 31 and a guiding section 32. The pressurizing section 31 gradually narrows its inner diameter in the direction away from the second end of the outlet duct 1 and is integrally connected with the guiding section 32, while the inner diameter of the guiding section 32 remains constant. The airflow entering the outlet duct 1 is pressurized twice by the pressurizing fan 24 and flows towards the second end of the outlet duct 1. The airflow first enters the pressurizing section 31 of the nozzle 3. Because the inner diameter of the pressurizing section 31 gradually decreases along with the airflow direction, the airflow is compressed within the pressurizing section 31, further increasing the pressure. The pressurized airflow continues to enter the guiding section 32, whose constant inner diameter maintains the increased airflow pressure, and finally exits the outlet duct 1 through the guiding section 32. The nozzle 3 further increases the outlet pressure when the airflow exits the second end of the outlet duct 1. Airflow with higher pressure can overcome more air resistance and flow to a farther location after entering an open environment, thus ensuring the delivery distance of the airflow after it exits the outlet duct 1.

[0035] Furthermore, a collar 33 is provided around the flow guide 32. The collar 33 is integrally extended from the outer wall of the pressurizing part 31. A reinforcing rib 34 is also provided between the collar 33 and the flow guide 32 to support and fix the flow guide 32, so as to prevent the flow guide 32 from being deformed and damaged when a high-pressure airflow passes through it.

[0036] The end of the collar 33 is provided with an outer folding ring 35. The inner diameter of the outer folding ring 35 is adapted to the outer diameter of the second end of the air outlet pipe 1. After the nozzle 3 is inserted into the second end of the air outlet pipe 1, the outer folding ring 35 covers the port of the second end of the air outlet pipe 1, so as to realize the connection, fixation and sealing of the nozzle 3 and the second end of the air outlet pipe 1.

[0037] This application also provides an air conditioning device, including a body 4 and an airflow control structure as described in the above embodiment. The body 4 is provided with a fan 41 and an air conditioning component. The air conditioning component may be at least one of an air cooling component, an air heating component, an air filtration component, an air disinfection component, and an air humidity control component.

[0038] In the embodiments of this application, the air conditioning component is an air cooling component, including a compressor 43, an evaporator 44, and a condenser (not shown in the figure). Additionally, a cooling fan 42 is installed inside the body 4. External air, driven by the fan 41, enters the body and is cooled by the evaporator 44 before entering the first chamber 21 of the air chamber 2. The cold air entering the first chamber 21 flows evenly into the air duct 1 and, under the combined action of the booster fan 24 and the air nozzle 3, is delivered at a higher pressure through the air duct 1, achieving temperature regulation for the corresponding usage location. The cooling fan 42 dissipates the heat generated by the operation of the air cooling component inside the body 4 from the other side of the body 4.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
