Description

Technical Field

[0001] This utility model relates to the technical field of air cooler structure, and in particular to an air cooler outlet structure. Background Technology

[0002] An evaporative air cooler is a machine that uses the evaporation of liquid water to achieve a cooling effect. Compared to air conditioners, evaporative air coolers are more energy-efficient, environmentally friendly, and lower in cost. Currently, some household upright evaporative air coolers mainly have an air outlet on the upper front of the unit for adjusting the airflow speed and direction.

[0003] The air outlet structure of evaporative air coolers is relatively simple, mostly using a louvered design. The main function of fixed louvers is safety, preventing users from accidentally touching the internal fan blades. However, they have poor airflow guidance, resulting in a harsh airflow, and the opening and closing of the outlet cannot be controlled. To improve airflow adjustment, air outlets with swingable louvers have appeared on the market. These structures typically use vertically or horizontally rotating louvers to change the direction of airflow.

[0004] However, this adjustment method has obvious limitations. The airflow area of ​​the air outlet is fixed, and the size of the air outlet cannot be adjusted without adjustment. Therefore, the airflow speed cannot be directly changed by changing the cross-sectional area of ​​the air outlet to adapt to different usage scenarios. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the airflow area of ​​the air outlet of a evaporative cooler is fixed, making it impossible to adjust the size of the air outlet and thus not be able to directly change the airflow speed by changing the cross-sectional area of ​​the air outlet to adapt to different usage scenarios. Therefore, this invention proposes an air outlet structure for a evaporative cooler.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cooler air outlet structure, including a body, a fixed pipe connected inside the air outlet duct of the body, a plurality of closed plates hinged to one end of the fixed pipe via a hinge seat, the plurality of closed plates being arranged in a conical shape around the fixed pipe, a frame slidably disposed inside the air outlet duct of the body, a connecting mechanism disposed inside the frame, the connecting mechanism being connected to the plurality of closed plates, and a driving component disposed inside the air outlet duct of the body, the driving component being connected to the frame, causing the frame to move within the air outlet duct of the body;

[0008] The connecting mechanism includes an arc-shaped slide groove formed on the closed plate, on which a rolling ball is slidably disposed. The top of the rolling ball is connected to a connecting rod via a bearing, and one end of the connecting rod is fixed to the inner side of the frame.

[0009] Preferably, the fixing tube is configured as a jacket structure, and sound-absorbing cotton is provided inside the jacket.

[0010] Preferably, the side of the frame that contacts the air outlet duct of the machine body is provided with a wear-resistant coating.

[0011] Preferably, one end of the air outlet pipe of the machine body is connected to a fixed frame, and a rotating shaft is mounted on the fixed frame via a bearing seat. A conical guide cover is connected to the end of the rotating shaft facing the closing plate.

[0012] Preferably, the conical guide cover has several ventilation holes and a spiral guide groove.

[0013] Preferably, some of the vent holes are arranged within the spiral guide groove.

[0014] Preferably, the fixed frame is provided with air guide vanes.

[0015] Preferably, a sealing strip is provided on the end face of the closing plate.

[0016] The air outlet structure of the air cooler proposed in this utility model has the following advantages:

[0017] 1. As the corresponding rolling balls slide on the arc-shaped groove via several connecting rods, they will cause several closed plates to rotate around the fixed tube, thereby opening one end of the closed plates and adjusting the size of the airflow channel, making it easier to adjust the airflow size to adapt to different usage scenarios.

[0018] 2. The airflow flows through the spiral guide groove on the conical guide cover, causing the conical guide cover to rotate. At the same time, some of the airflow passes through several vents, dispersing the airflow. The dispersed airflow blows the guide vanes, causing the guide vanes to rotate on the fixed frame, further dispersing the airflow and increasing the blowing range, thereby improving the practicality of the device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figure 1-6 A cooler air outlet structure includes a body 1, a fixed pipe 2 fixedly installed inside the air outlet pipe of the body 1, a plurality of closed plates 3 hinged to one end of the fixed pipe 2 via a hinge seat, the plurality of closed plates 3 being arranged in a conical shape around the fixed pipe 2, a frame 4 slidably disposed inside the air outlet pipe of the body 1, a connecting mechanism disposed inside the frame 4, the connecting mechanism being connected to the plurality of closed plates 3, and a driving component 5 disposed inside the air outlet pipe of the body 1, the driving component 5 being connected to the frame 4, causing the frame 4 to move inside the air outlet pipe of the body 1;

[0028] The connecting mechanism includes an arc-shaped slide 6 formed on the closed plate 3. A baffle is provided on the top of the arc-shaped slide 6 to prevent the rolling ball 7 from falling off the arc-shaped slide 6, thereby improving the stability of the device. The rolling ball 7 is slidably arranged on the arc-shaped slide 6. The top of the rolling ball 7 is connected to a connecting rod 8 through a bearing. One end of the connecting rod 8 is fixed on the inner side of the frame 4.

[0029] Usage: After air is discharged from the air outlet pipe of the unit 1, during the adjustment process, the drive component 5 is activated. After the drive component 5 drives the frame 4 to move inside the air outlet pipe of the unit 1, the frame 4 will move through several connecting rods 8. As the connecting rods 8 slide on the arc-shaped slide groove 6 with the corresponding rolling balls 7, they will bring several closing plates 3 to rotate around the fixed pipe 2, thereby opening one closed end of the closing plates 3, thus adjusting the size of the airflow channel, making it easier to adjust the air outlet size to adapt to different usage scenarios, and improving the practicality of the equipment.

[0030] Example 2: In Example 1, the air outlet duct of unit 1 generates significant noise, affecting the comfort of nearby personnel. Based on Example 1, optimizations are made, referencing... Figure 1-6 The fixed tube 2 is configured as a jacket structure, and the jacket is equipped with sound-absorbing cotton 16. The sound-absorbing cotton 16 absorbs noise, thereby reducing the noise generated by the device and improving the comfort during the use of the device.

[0031] Example 3: In Example 1, the effect of fixing the tube 2 using several closed plates 3 was poor. Based on Example 1, optimizations were made, referring to... Figure 1-6 The side of the frame 4 that contacts the air outlet pipe of the body 1 is provided with a wear-resistant coating. The wear-resistant coating is formed by spraying ceramic particles, thereby improving the stability of the device operation.

[0032] Example 4: In Example 1, the gaps between the closed plates 3 are relatively large, resulting in significant air leakage during the closing process. (Reference) Figure 1-6 Sealing strips 14 are fixedly installed on both ends of the closing plate 3. The sealing strips 14 are made of silicone material. After several closing plates 3 are closed around each other, air leakage is not likely to occur between the several closing plates 3, thereby improving the effect of the device.

[0033] Example 5: In Example 1, the airflow between several closed plates 3 is more concentrated, resulting in a smaller airflow range. An optimization is made based on Example 1, referencing... Figure 1-6 One end of the air outlet pipe of the unit 1 is detachably mounted with a fixed frame 9 by bolts. A rotating shaft 10 is mounted on the fixed frame 9 via a bearing seat. A conical guide shroud 11 is connected to the end of the rotating shaft 10 facing the closing plate 3. Several ventilation holes 12 are opened on the conical guide shroud 11. A spiral guide groove 15 is provided on the conical guide shroud 11. Some of the ventilation holes 12 are arranged in the spiral guide groove 15. A guide vane 13 is mounted on the fixed frame 9 via a bearing seat.

[0034] Usage process: After the airflow between several closed plates 3 reaches the conical guide cover 11, the airflow will flow on the spiral guide groove 15 on the conical guide cover 11, causing the conical guide cover 11 to rotate. At the same time, some airflow will pass through several vent holes 12, causing the airflow to be dispersed. The dispersed airflow will blow the guide vane 13, causing the guide vane 13 to rotate on the fixed frame 9, causing the airflow to be dispersed again, thereby increasing the blowing range and improving the practicality of the device.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
