As shown in fig. 1 and 2, an air-conditioning duct assembly according to an embodiment of the present invention includes:
the air conditioner air duct 1 is used for enabling air flow to flow along the axial direction of the air conditioner air duct 1 (as shown by arrows in the figure);
the sensor is used for measuring the parameters of the air in the air-conditioning air pipe 1; and
the dust cover 2 is fixedly arranged on the pipe wall of the air-conditioning air pipe 1, and the sensor is fixed in the dust cover 2.
According to the air conditioner air duct assembly provided by the embodiment of the invention, the dust cover 2 is arranged on the outer side of the sensor, so that dust-containing air is prevented from blowing to the sensor, and the cleaning time of the sensor is further prolonged to obtain a more accurate measurement value.
The sensor may be a humidity/temperature meter for measuring the temperature/humidity of the air, a speed sensor for measuring the wind speed of the air, or the like. In this embodiment, the sensor is a hygrometer.
In the present embodiment, the dust cap 2 is a square housing. And the side of the dust cover 2 comprises a windward side located at the upstream side of the air flow, a leeward side arranged at the downstream side of the air flow and two air flow parallel sides parallel to the flowing direction of the air flow, and the windward side is arranged in a closed manner. The windward side is sealed, so that air can be prevented from directly blowing the sensor, and dust in the air can be prevented from directly polluting the sensor.
The parallel side of the air flow of this embodiment is provided with at least one air inlet opening 9. The dust cover 2 is characterized in that the air inlet holes 9 are formed in the side face, parallel to the air flow direction, of the dust cover 2, when air passes through the air inlet holes 9 and enters the wind cover 2, the air speed is reduced, dust is settled, and compared with a direct blowing sensor, the pollution to the sensor is reduced.
In the embodiment, at least one of the two airflow parallel sides is provided with an air inlet hole 9.
The at least one air inlet opening 9 of the present embodiment is arranged close to the probe of the sensor. The arrangement makes the detection of the humidity and the temperature of the air by the probe of the sensor more accurate.
The leeward side of this embodiment is provided with at least one air outlet 10. Since the pressure on the lee side of the dust cover 2 is reduced, air flows out of the dust cover 2 through the air outlet holes 10 after passing through the air inlet holes 9 and entering the interior of the windshield 2.
As shown in fig. 2, the air outlet 10 of the present embodiment is located below the air inlet 9 in the height direction. The air flow path will then pass the probe of the sensor so that the probe is in sufficient contact with the air flow to improve the accuracy of the test.
The dust cover 2 of the present embodiment is provided with a dust exhaust hole on its lower end surface. After the air current gets into dust cover 2 in through fresh air inlet 9, the dust that contains in the air current subsides downwards, and then drops in air conditioner tuber pipe 1 through the dust exhaust hole.
Specifically, in the present embodiment, the lower end surface of the dust cover 2 is open. The dust is settled downwards and directly falls into the air-conditioning air pipe 1.
The air conditioner air duct assembly of this embodiment still includes the retainer plate, and the retainer plate sets up in dust cover 2 and is used for fixed sensor.
The structure of an air-conditioning duct assembly according to an embodiment of the present invention will be described in detail with reference to fig. 1 and 2.

The humidity and temperature meter 6 is fixedly arranged in the dust cover 2, and the dust cover 2 is arranged on the air-conditioning air pipe 1.
As shown in fig. 2, the dust cover 2 is a rectangular parallelepiped case. The dust cover 2 includes an upper end surface, a lower end surface, and four side surfaces.
The upper end surface of the dust cover 2 is provided in an open manner. And two sides of the upper end surface of the dust cover 2 are provided with flanges 3. The flanging 3 is fixed on the air-conditioning air pipe 1 through a gasket 4 and a screw.
The four sides of the dust cover 2 include a windward side, a leeward side and two airflow parallel sides parallel to the flow direction of the airflow. Wherein the windward side is arranged in a closed manner. The parallel side of the airflow is provided with an air inlet hole 9. The leeward side is provided with an air outlet 10. Specifically, the dust cover 2 of the present embodiment has a plurality of air inlet holes 9 on the air flow parallel side and a plurality of air outlet holes 10 on the lee side. A plurality of air inlet holes 9 are arranged near the probe of the hygrothermograph 6 and are positioned at the upper side of the hygrothermograph 6. The air outlet holes 10 are arranged close to the probe of the hygrothermograph 6 and are positioned at the lower side of the air inlet holes 9. The windward side 14 of the dust cover 2 is of a closed structure, so that dust-containing airflow is prevented from directly entering the dust cover. The upstream air flow in the air-conditioning air pipe 1 can enter the dust cover 2 through the air inlet hole 9, and after passing through the probe of the humidity-temperature meter 6, the air flow enters the downstream air flow of the air-conditioning air pipe through the air outlet hole 10.
In the embodiment, a plurality of air inlet holes 9 are formed in the two parallel air flow sides. As the air flows through the dust cap 2, it enters the dust cap 2 through the air inlet holes on the two parallel sides of the air flow to equalize the temperature of the air inside and outside the dust cap 2.
The lower end surface of the dust cover 2 is opened, and dust in the dust cover 2 is discharged through the lower end surface.
The dust cover 2 of the present embodiment is made of stainless steel. The dust cover 2 has good heat-conducting properties and corrosion-preventing properties.
As shown in fig. 2, a fixing ring is further disposed in the dust cover 2 of the present embodiment, and the fixing ring is disposed in the dust cover 2 and used for fixing the sensor. Specifically, the fixing ring of the present embodiment includes a first fixing ring 7 and a second fixing ring 8 that are provided at intervals in the height direction.
In this embodiment, the retainer ring is a rubber ring. When the hygrothermograph 6 is fixed, the first fixing ring 7 and the second fixing ring 8 are fixed in the inner cavity of the dust cover 2 by glue. The hygrothermograph 6 is then passed through the inner bores of the first and second fixing rings 7, 8 and fixed tightly to the first and second fixing rings 7, 8. The hygrothermograph 6 and the fixing ring are arranged in an interference fit mode to reduce air leakage.
In other embodiments, the retaining ring is movably disposed within the interior cavity of the dust cap 2. The position of the fixing ring can be adjusted according to the target position of the probe of the hygrothermograph 6.
After the device is used for a period of time, the thermo-hygrometer 6 can be pulled out manually to clean the thermo-hygrometer 6, and the thermo-hygrometer 6 is inserted back into the dust cover 2 after cleaning.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
