Description

Technical Field

[0001] The present invention relates to the technical field of air outlet equipment, and in particular to an air outlet control device at the terminal of an air conditioner. Background Art

[0002] The air conditioning terminal is a device that can turn chilled water or refrigerant into cold air. It is generally found in the terminal equipment of the central air conditioning system and is often located indoors. Common ones include: mainly refers to the fresh air system, fan coil, temperature control switch, water flow control valve. In the air conditioning system, the combination of devices for heating, humidifying, cooling, dehumidifying, purifying and silencing the air is called air heat and humidity treatment equipment, commonly known as air conditioning terminal equipment; During the air conditioning refrigeration cycle, the refrigerant will absorb the indoor heat through the evaporator, so the evaporation temperature will be relatively low, usually only about 10°C. During the operation of the air conditioner, the indoor air will be sucked into the air conditioner, and after being filtered, heated, cooled, etc., it will be discharged to the outside through the air outlet. In this process, the indoor air will be cooled by the condenser, and the temperature of the condenser is usually much higher than that of the evaporator, usually reaching more than 20°C. Therefore, when the air conditioner is in the refrigeration cycle, the indoor air will first be cooled by the evaporator, and then heated again by the condenser and discharged to the outside through the air outlet. The air outlet of a traditional central air conditioner is provided with an air guide blade group, which cannot change the air guide direction. In the cold winter, the air conditioner discharges warm air, which has a smaller density than the indoor air. If the air guide blade group is placed horizontally, the warm air goes up, and it will feel cold in winter. In the prior art, in order to change the air guide direction, it is necessary to manually turn the air guide blade group to change the wind direction of the air guide blade group, which wastes manpower.

When the temperature of the air outlet of the air conditioner 1 is set to be between 26°C and 28°C in the heating mode, it is a normal temperature. When the air conditioner 1 is in the heating mode, the operator manually sets the safety temperature of the fixed temperature detector 6 to 28°C. If the fixed temperature detector 6 detects that the temperature of the air outlet of the air conditioner 1 is higher than 28°C in the heating mode, it automatically sends an alarm signal to prompt the operator that a fault occurs inside the air conditioner 1, causing the temperature of the air outlet to rise. At this time, the operator shuts down the air conditioner 1 and inspects the inside of the air conditioner 1. When the air conditioner 1 is in cooling mode, the air conditioner 1 discharges cold air to the outside through the air outlet. The operator starts the first air guide unit and the second air guide unit, and rotates the first air guide plate 12 and the second air guide plate 14 counterclockwise around the first rotating shaft 11 and the second rotating shaft 13, so that the cold air generated by the air conditioner 1 is discharged to the outside. At the same time, the control system starts the temperature measuring unit to monitor the temperature of the air outlet of the air conditioner 1 in real time. When the air conditioner 1 is in cooling mode, the temperature of the air outlet is set to between 18°C ​​and 26°C, which is a normal temperature. When the air conditioner 1 is in cooling mode, the operator manually sets the safety temperature of the fixed temperature detector 6 to 26°C. If the fixed temperature detector 6 detects that the temperature of the air outlet is higher than 26°C in the heating mode of the air conditioner 1, it automatically sends an alarm signal to prompt the operator that a fault occurs inside the air conditioner 1, causing the temperature of the air outlet to rise. At this time, the operator shuts down the air conditioner 1 and inspects the inside of the air conditioner 1. S2, start the distance measuring unit to detect the distance between the human body and the air conditioner 1 in real time, and adjust the wind speed at the air outlet; Specifically, when the air conditioner 1 starts working, the speed measuring unit is started to detect the wind speed at the air outlet of the air conditioner 1, and the distance measuring unit is started to detect the distance from the human body to the air conditioner 1. When the wind speed felt by the human body is set to S, it is the optimal comfortable wind speed for the human body. The calculation formula of the wind speed S value felt by the human body is as follows: S= -L / T in, is the wind speed at the air outlet of the air conditioner 1, L is the distance from the human body to the air conditioner 1, T is the time it takes for the human body to walk under the air conditioner 1, and T is a fixed value set manually; Since the distance between the human body and the air conditioner 1 is different, when the wind speed felt by the human body is S, it is necessary to adjust the distance L detected by the distance measuring unit. Adjustment is made, because the distance between the human body and the air conditioner 1 is Therefore, when the distance measuring unit detects that the distance from the human body to the air conditioner 1 becomes smaller, the operator starts the second air guide unit and reduces the rotation angle of the second air guide plate 14. The rotation angle of the first air guide plate 14 is the angle formed by the surface of the first air guide plate 14 and the axis of the second rotating shaft 13. By adjusting the rotation angle of the second air guide plate 14 Adjust accordingly; When the distance measuring unit detects that the distance between the human body and the air conditioner 1 becomes larger, the operator starts the second air guide unit and increases the rotation angle of the second air guide plate 14. Increase accordingly to keep the wind speed S felt by the human body at the optimal comfortable wind speed; S3, after the air conditioner 1 has been operating for a period of time, the dust concentration detection unit is started to detect the dust concentration inside the air conditioner 1, and the dustproof net 19 is replaced.

[0009] Specifically, when the air conditioner 1 is started, the operator starts the dust concentration detection unit to detect the dust concentration attached to the surface of the dustproof net 19. When the dust concentration of the dustproof net 19 is set to 50%-70%, it is a usable dustproof net, and 50%-70% is the percentage of the area of ​​the dust occupied by the surface of the dustproof net 19 to the surface area of ​​the dustproof net 19; When the dust concentration detection unit detects that the dust concentration of the dustproof net 19 is greater than 70%, it indicates that the dustproof net needs to be replaced. The operator removes the dustproof net 19 from between the upper fixing rod 17 and the lower fixing rod 18 for replacement; When the dust concentration detection unit detects that the dust concentration of the dustproof net 19 is 50%-70%, the operator starts the first air guide unit and fine-tunes the rotation angle of the first air guide plate 12 by 15° to reduce the entry of dust and increase the service life of the dustproof net 19.
