Description

Technical Field

[0001] The invention relates to the field of wind force detection, in particular to a wind force detection device for a central air conditioner. Background Art

[0002] Central air conditioning is a facility that controls the temperature, humidity, air circulation and other factors of an entire building or an area through a centralized system. It consists of one or more outdoor units and indoor units. The outdoor unit discharges indoor heat to the outside by transmitting cold (hot) media, and the indoor unit regulates the indoor temperature by transferring cold (hot) media to the air. Through centralized control, it can provide a more comfortable indoor environment with lower energy consumption.

[0003] Since tiny particles such as dust, dirt, and mold in the air are constantly suspended in the air and accumulate in the filters of the central air conditioner for a long time, they will eventually enter the air duct and accumulate around the air outlet to form thick layers of dust. The existing Chinese public patent document: Chinese invention patent CN108981084A discloses an air outlet panel and an air conditioner. A wind detector is installed on the air outlet panel of the air conditioner so that the wind detector can monitor the wind force of the air conditioner in real time. Although the above-mentioned wind detector can detect the blockage of the pipeline in real time, since the air outlet panel of the central air conditioner is relatively long, when the air outlet panel is partially blocked and there is a lot of dust accumulation, the dust accumulation will cover the outside of the wind detector, causing obstruction to the sensing position of the wind detector, and the wind detector cannot accurately detect the airflow discharged by the air conditioner.

[0036] The movable bar 9 pushes the push plate 35 to move, so that the scraper bar 20 and the scraper frame 21 push the dust into the storage box 34, and when the scraper bar 20 and the scraper frame 21 are in contact with the corresponding knocking rods 37 respectively, the elasticity of the scraper bar 20 and the scraper frame 21 is used to shake out the dust, thereby achieving the effect of facilitating dust collection and facilitating the user's later cleaning.

[0037] Working principle: First, the user installs the air outlet 1 on the exhaust pipe of the central air conditioner through two installation strips 8, and connects the control end of the central air conditioner with the wind detector 7 and the electric screw 10. The central air conditioner control end opens the electric screw 10, and the electric screw 10 drives the moving strip 9 to move along the inner side of the air outlet 1, so that the arc surface on the moving strip 9 contacts the arc surface of the movable column 12, and the movable column 12 is pushed to move in the air outlet 1, so that the movable column 12 pushes one end of the rocker 11 to swing upward through the two slide bars 16 on the connecting plate 15, and the slide seat 17 on the connecting plate 15 is inserted into the fixed The two plug posts 18 are placed in the sliding cavity of the position seat 6 so that the two plug posts 18 are against the annular groove on the sliding seat 17 to position the movable column 12. The other end of the rocker 11 can push the sliding rod 16 on the other connecting plate 15 to move downward, so that the connecting plate 15 extends the wind force sensing head 14 on the detection column 13 to the inner side of the air outlet 1. At the same time, the moving bar 9 drives the scraping bar 20, the scraping frame 21 and the pushing bar 33 to move synchronously. The scraping bar 20 and the scraping frame 21 respectively push and clean the dust accumulated on the inner side of the air outlet 1 and the dust accumulated on the outer side of the air guide plate 2. As the moving bar 9 moves, the arc surface of the pushing bar 33 is aligned with the arc surface of the U-shaped plate 29. The U-shaped plate 29 is in contact with the positioning block 31, and the U-shaped plate 29 drives the gear 28 to rotate through the rack 30, so that the gear 28 drives the rotating rod 26 to rotate, and the rotating rod 26 drives the adjusting rod 24 to rotate synchronously through the synchronous belt 27. The threads on the adjusting rod 24 drive the multiple adjusting blocks 25 to move, and the multiple adjusting blocks 25 drive the corresponding baffle plate 1 22 and baffle plate 23 to open the ash discharge port 1 and the ash discharge port 2 on the air outlet 1 respectively. The scraper strip 20 and the scraper frame 21 push the accumulated dust from the ash discharge port 1 and the ash discharge port 2 into the storage box 34, and the moving strip 9 can push the push plate 35 The spring three 36 is compressed to make the scraper strip 20 and the scraper frame 21 contact the corresponding knocking rod 37 respectively. The elasticity of the scraper strip 20 and the scraper frame 21 is used to pour the dust into the storage box 34, which is convenient for the user to clean it in a centralized manner. Finally, the electric screw 10 moves the moving strip 9 to the right inner wall of the air outlet 1, and the push plate 35 is reset by using the spring three 36. The central air conditioner starts to blow air, and the wind force detector 7 is turned on by the control end to make the wind force sensing head 14 run. The multiple wind force sensing heads 14 perform multi-point detection on the wind force inside the air outlet 1, thereby achieving the effect of accurate detection and convenient cleaning of dust accumulation.

[0038] When the central air conditioner stops blowing air, the control end starts the electric screw 10 to make the electric screw 10 pull the moving bar 9 to move back. The arc surface of the moving bar 9 contacts the arc surface of the wind sensor head 14, pushing the wind sensor head 14 into the air outlet 1, providing protection for the wind sensor head 14 and preventing the dust suspended inside the air outlet 1 from polluting the wind sensor head 14.

A clamping plate 40 is fixedly connected to both sides of the positioning block 31. The clamping plate 40 contacts the outer side of the U-shaped plate 29 to facilitate the smooth movement of the U-shaped plate 29.

[0040] In this embodiment: the wind sensing head 14 can dock with the wind detector 7 on the positioning seat 6 through the elastic data line 38 on the slide seat 17, and transmit the detected data to the wind detector 7. When moving, the U-shaped plate 29 can move along the outer side of the guide rod 39 and the card plate 40 to improve the stability of the movement of the U-shaped plate 29.

[0041] Example 3: Please refer to Figure 1 , Figure 3 and Figure 5 , this embodiment further explains other embodiments. Two symmetrically distributed support rods 41 are fixedly connected between the air guide plate 2 and the inner side of the storage box 34 in the figure. The corresponding surfaces of the two baffles 23 are provided with arc-shaped grooves in contact with the outer sides of the support rods 41 to provide support for one end of the air guide plate 2. Two symmetrically distributed limit blocks 42 are fixedly connected to the outer side of the push plate 35. The limit blocks 42 are in contact with the right side of the air outlet tube 1 to facilitate the reset of the push plate 35. A transparent plate 43 is installed on the outer side of the storage box 34 to facilitate the observation of the dust collection in the storage box 34.

[0042] In this embodiment: the support rod 41 can provide support for one end of the air guide plate 2, so as to provide guidance for the airflow. When the moving bar 9 moves away from the push plate 35, the spring three 36 can push the push plate 35 to reset, so that the two limit blocks 42 are against the right side of the air outlet tube 1, providing a seal between the storage box 34 and the air outlet tube 1, and the user can observe the dust collection situation inside the storage box 34 through the transparent plate 43 on the storage box 34. When there is a lot of dust, it can be disassembled for cleaning.
