Description

Technical Field

[0001] This utility model relates to the field of air conditioning vent technology, specifically to a wheel-type temperature-controlled strip vent. Background Technology

[0002] The ideal airflow pattern for an air conditioning system is such that in winter, warm air can be delivered to areas where people are active, providing effective heat and ensuring an effective airflow distance. In summer, the low-temperature airflow in the cold air mixes rapidly with the surrounding warm air, resulting in a smaller temperature difference between the airflow delivered to the work area and the surrounding air, avoiding direct cold air blowing. Due to the characteristics of hot and cold air, ordinary air outlets can hardly meet the airflow requirements of both winter and summer simultaneously, especially for ceiling-mounted air supply in large spaces, where the airflow distance is long and cannot meet the airflow requirements of both winter and summer at the same time.

[0003] Currently, the air delivery angle of existing horizontal air outlets is usually 30°-50°, which has poor adhesion and short range. Horizontal air supply itself is affected by vertical airflow. A large air delivery angle and poor adhesion will result in the impeller having a similar air inlet and outlet area, no jet effect, low air delivery speed, poor induction performance and poor indoor heat exchange performance, and the air supply effect cannot be guaranteed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wheel-type temperature-controlled strip air outlet, which can solve the problem that existing air outlets cannot simultaneously meet the air supply requirements in winter and summer, and improve the air supply effect in both winter and summer.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A wheel-type temperature-controlled strip air outlet includes an outer frame, within which several blade assemblies are installed. A thermodynamic element is mounted on the outer frame via a bracket, and the thermodynamic element is connected to the blade assemblies via a linkage mechanism to drive the blade assemblies to rotate. Each blade assembly includes two opposing arc-shaped blades, the two ends of which are respectively connected to a rotating wheel, which is rotatably mounted on the inner sidewall of the outer frame. A vertically arranged baffle capable of adjusting the airflow direction is also installed on the outer frame, and the baffle is positioned between the two opposing blades.

[0007] The aforementioned wheel-type temperature-controlled strip air outlet has two oppositely arranged blades forming an arc-shaped chamber. The upper ends of the two blades form the air inlet of the arc-shaped chamber, and the lower ends of the two arc-shaped blades form the air outlet of the arc-shaped chamber. The vertical central axis of the partition is aligned with the vertical central axis of the arc-shaped chamber.

[0008] The aforementioned wheel-type temperature-controlled strip air outlet includes a thermal element comprising a temperature sensing part and a moving part. The moving part is connected to a rotating wheel via a linkage mechanism. A compression spring is provided between the moving part and the bracket to stretch and reset the moving part after the temperature sensing part contracts due to cold, thereby driving the moving part to move upward.

[0009] The aforementioned wheel-type temperature-controlled strip air outlet includes a linkage mechanism comprising a top rod connected to the moving part of a thermal element and a connecting rod installed at one end of a rotating wheel; the top of the connecting rod is provided with a connecting protrusion, which is hinged to the bottom of the top rod.

[0010] In the aforementioned wheel-type temperature-controlled strip air outlet, the top rod and the moving part are connected by a bolt assembly. The top rod is also provided with an inclined slot that slides with the bolt assembly and allows the top rod to move under the drive of the moving part.

[0011] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0012] This invention provides a wheel-type temperature-controlled strip air outlet. By using the thermal expansion and contraction characteristics of the thermal element to drive the blade rotation, it achieves the switching between vertical air supply mode in winter and horizontal air supply mode in summer. Moreover, by setting a baffle in the arc cavity formed by the two blades, the influence of vertical airflow during horizontal air supply is eliminated. At the same time, the vertical setting of the baffle can also ensure that the baffle does not generate a large resistance to the vertical airflow during vertical air supply, thus meeting the needs of both winter and summer air supply.

[0013] This invention can achieve 10% to 15% horizontal air supply during horizontal air supply, and reduce the air supply angle to 15°-20°. By adjusting the angle of the air inlet and outlet, combined with the wind-blocking effect of the partition, the air supply channel forms a contraction structure, ensuring a certain airflow jet at the air outlet, increasing the air supply distance and outlet air velocity, enhancing the induction effect on indoor air, improving the heat exchange effect between primary air and indoor air, and promoting indoor comfort.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] A type of wheel-type temperature-controlled strip air outlet, such as Figures 1 to 6 As shown, it includes an outer frame 1, inside which several blade assemblies are installed. A thermodynamic element 3 is installed on the outer frame 1 via a bracket 4. The thermodynamic element 3 is connected to the blade assembly via a linkage mechanism and drives the blade assembly to rotate.

[0023] The blade assembly includes two opposing arc-shaped blades 2, which together form an arc-shaped chamber. The upper ends of the two blades 2 form the air inlet of the arc-shaped chamber, and the lower ends of the two arc-shaped blades 2 form the air outlet of the arc-shaped chamber.

[0024] The two ends of the arc-shaped blade 2 are connected to the rotating wheel 10. The rotating wheel 10 is rotatably mounted on the inner side wall of the outer frame 1. The rotating wheel 10 drives the blade 2 to rotate so as to adjust the change of airflow direction and the conversion of dynamic pressure and static pressure.

[0025] The outer frame 1 is also equipped with vertically arranged partitions 6, such as Figure 2 As shown, the baffle 6 is set between two opposite blades 2, and the vertical central axis of the baffle 6 is aligned with the vertical central axis of the arc chamber. By setting the baffle 6 between the two opposite blades 2, the influence of vertical airflow on horizontal air supply is eliminated. At the same time, the baffle 6 is relatively thin and will not generate too much resistance to the vertically downward airflow, which is beneficial for vertical air supply in winter.

[0026] The thermal element 3 includes a temperature sensing part and a moving part, wherein the moving part is connected to the rotating wheel 10 through a linkage mechanism.

[0027] A compression spring 9 is provided between the moving part and the support 4. One end of the compression spring 9 is installed at the bottom of the moving part, and the other end is installed at the top of the support 4 located below the moving part. When the temperature sensing part is heated, it expands and causes the moving part to move down and compress the compression spring 9. When the temperature sensing part is cooled and contracts, the compression spring 9 stretches and returns to its original position, and the moving part moves upward under the action of the compression spring 9.

[0028] The linkage mechanism includes a top rod 5 connected to the moving part of the thermal element 3 and a connecting rod 7 installed on one end of the rotating wheel 10. The top of the connecting rod 7 is provided with a connecting protrusion 8, which is hinged to the bottom of the top rod 5.

[0029] The push rod 5 is connected to the moving part by a bolt assembly, which includes a bolt and a nut. The push rod 5 is also provided with an inclined slot that slides with the bolt assembly, which enables the bolt assembly to drive the push rod 5 to move within the inclined slot, thereby driving the blade assembly to rotate and realizing the switching of the air supply mode.

[0030] The working principle of this utility model is as follows: When hot air is supplied in winter, the temperature sensing part on the thermal element 3 senses the hot air and expands due to heat, pushing the moving part downward and compressing the compression spring 9 downward. Figure 3 As shown, at the same time, the moving part moves down, causing the push rod 5 to move down. The push rod 5 drives the rotating wheel 10 to rotate counterclockwise through the connecting rod 7, and the blade 2 rotates with the rotating wheel 10.

[0031] When the temperature sensed by the temperature sensing unit exceeds 26°C, the moving part stops moving downwards, and one end of the push rod 5 abuts against the inside of the outer casing 1. At this time, the blades 2 on both sides of the partition 6 are symmetrically arranged relative to the vertical central axis of the partition 6. Figure 4 As shown, the air inlet and outlet of the arc-shaped chamber are arranged vertically opposite each other to ensure that air can be delivered vertically downwards during winter.

[0032] When cold air is delivered in summer, the temperature sensing part on the thermal element 3 senses the cold air and contracts upon cooling, no longer compressing the spring 9. The spring 9 stretches and resets, driving the moving part to move upward. At the same time, the top rod 5 also moves upward. Under the action of the linkage rod 7, it drives the rotating wheel 10 to rotate clockwise. At this time, the line connecting the air inlet and outlet of the arc chamber is set at an angle. At the same time, under the action of the partition 6, the influence of some vertical airflow is eliminated, ensuring the air delivery effect of horizontal air supply.

[0033] When the temperature is between 20℃ and 26℃, the compression spring 9 stretches upward and deforms proportionally with the temperature change, causing the push rod 5 to move upward.

[0034] When the temperature is below 20℃, the compression spring 9 returns to its original position and no longer deforms. At this time, the blade air delivery angle is as follows: Figure 6 As shown, the end of one of the blades 2 contacts the partition 6, and the air supply channel is constricted, resulting in better air supply adhesion and a smaller air supply angle, which can create a better induction effect and improve indoor comfort.

[0035] This invention provides a wheel-type temperature-controlled strip air outlet. By using the thermal expansion and contraction characteristics of the thermal element to drive the blade rotation, it achieves the switching between vertical air supply mode in winter and horizontal air supply mode in summer. Moreover, by setting a baffle in the arc cavity formed by the two blades, the influence of vertical airflow during horizontal air supply is eliminated. At the same time, the vertical setting of the baffle can also ensure that the baffle does not generate a large resistance to the vertical airflow during vertical air supply, thus meeting the needs of both winter and summer air supply.

[0036] In summer, horizontal air supply can achieve 10% to 15% horizontal air supply, with the air supply angle reduced to 15°-20°. By adjusting the angle of the air inlet and outlet, combined with the wind-blocking effect of the partition, the air supply channel forms a contraction structure, ensuring a certain airflow jet at the air outlet. This increases the air supply distance and outlet air velocity, enhances the induction effect on indoor air, improves the heat exchange effect between primary air and indoor air, and promotes indoor comfort.

[0037] When vertical air supply is used in winter, the vertically arranged partitions and their relatively small thickness do not create much resistance to the vertically downward airflow. The air supply area ratio of vertical air supply is about 60%, which does not affect the air supply effect in winter.
