Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the invention in a schematic manner, and only the components related to the invention are shown in the drawings rather than being drawn according to the number, shape and size of the components in actual implementation, and the form, quantity and proportion of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.
Referring to fig. 1-2, it should be noted that the air suction pipe is installed at the air suction port of the blower of the main air conditioner of the automobile (not shown in fig. 1). The air suction pipe of this embodiment includes air suction pipe body 1, keep away from air-blower induction port position department in air suction pipe body 1 and install an indoor temperature sensor 2 and constitute the air suction pipe assembly, indoor temperature sensor 2's mounting means can adopt bolt or screw connection, or rivet, fix it inside air suction pipe body 1, the purpose that sets up like this is to ensure to form the gas pressure difference between air in the car and the air-blower air inlet in the use, the air suction pipe assembly pressure that is close to the air-blower air inlet can be higher than 2 probe position departments pressures of indoor temperature sensor, indoor temperature sensor 2 surrounds by the air in the car that inhales the air-blower import this moment, the temperature that indoor temperature sensor 2 perception is promptly temperature in the car. The indoor temperature sensor 2 is a thermistor or a platinum resistor, and specifically an NTC thermistor can be selected.
In this embodiment, the aspiration channel adopts the bellows, makes things convenient for the pipeline trend, and owing to receive the mounted position restriction (as shown in fig. 1) at the loading state, the inside air current is unsmooth in intraductal flow field after the aspiration channel breathes in, and the local high-speed air current that produces (the biggest speed of the fan reaches 28m/s in the aspiration channel) leads to producing the whistle sound, consequently, the aspiration channel still includes separation blade 3, sets up above-mentioned separation blade 3 on the high pressure region that produces by the flow field in aspiration channel body 1, and this separation blade 3 is according to the rotation angle of the regional pressure differential automatic adjustment separation blade 3 of both sides of high pressure.
Preferably, the baffle 3 is a circular baffle, and the diameter of the baffle 3 is adapted to the diameter of the suction pipe body 1.
In an embodiment, referring to fig. 3-4, one end of the blocking piece 3 is connected to the inner wall of the suction pipe body 1 through a limiting shaft 31, specifically, one side is selected in the circumferential direction of the blocking piece 3, the side is inserted with one end of the limiting shaft 31, the other end of the limiting shaft 31 is connected to the inner wall of the suction pipe body 1, and the blocking piece 3 can rotate with the limiting shaft 31 as a rotation axis. In order to prevent the baffle 3 from shaking in the rotating process, the other end of the baffle 3 is mounted on the air suction pipe body 1 through the rotating shaft 32, and the rotating shaft 32 and the limiting shaft 31 can be interchanged. In another embodiment, the blocking sheet 3 may also be formed by directly penetrating the limiting shaft 31 from one end of the circumference of the blocking sheet 3 to the other end of the circumference of the blocking sheet 3 through the center of the blocking sheet 3, so as to integrate the limiting shaft 31 and the blocking sheet 3.
In order to ensure that the baffle plate 3 cannot completely block the air suction pipe in the rotating process, a limiting groove 33 is formed in the outer pipe wall of the air suction pipe body 1, one end of a limiting shaft 31 extends to the outer pipe wall of the air suction pipe body 1, and one end of the limiting shaft 31 is arranged in the limiting groove 33 and can slide in a reciprocating manner, so that the maximum rotating angle of the swing of the baffle plate 3 is limited. The angle range of the baffle plate 3 is initially set to be 45-90 degrees according to the bench test, and when the angle of the baffle plate 3 shown in figure 2 is that the rotating angle of the baffle plate 3 is 90 degrees, the air opening is fully opened.
In this embodiment, the air-blower has seven gears, every gear wind pressure increases progressively gradually, wherein the pressure of induced drafting of seventh gear is the biggest, utilize the utility model discloses a behind the aspiration channel, under one shelves ~ third gear amount of wind, separation blade 3 position is maintained at the intermediate position basically and is that 3 angles of separation blade are in 90, the amount of wind begins to seven shelves from the fourth gear, separation blade 3 increases at aspiration channel high pressure area's pressure when the air-blower induced air, pressure differential appears in 3 both sides of separation blade this moment, separation blade 3 is rotatory gradually, make the opening between separation blade 3 and the aspiration channel body 1 diminish, thereby adjustment both ends pressure reaches the balance, avoid the aspiration channel inside to lead to there being the whistle sound because of producing air current rapidly.
By utilizing the structure, the increased baffle piece 3 can adjust the opening size of the high-pressure area of the air suction pipe according to the pressure difference at the two ends of the air suction pipe, the phenomenon that a large amount of air is generated in a pipeline by high-speed airflow to generate whistle sound due to the fact that the pressure difference at the two ends of the air suction pipe is large is avoided, meanwhile, the structure can be suitable for being used under different air quantities, and the universality effect is good.
The utility model also provides an air conditioner, including the aforesaid aspiration channel.
