The invention provides an air conditioner which comprises the fresh air system.
The invention provides a method for removing wind-blocking foreign matters from a fresh air system, which comprises the following steps:
step 100, starting: starting the fresh air system, opening the air door to the maximum angle, operating at the maximum wind gear, and continuing to a stable state;
step 200, wind resistance judgment: the air quantity monitoring element acquires the static pressure value at the inlet of the air inlet cavity in real time, and when the acquired static pressure value is increased, the amount of the wind-blocking foreign matters at the filter screen is too large, and the foreign matters need to be cleaned;
step 300, foreign matter cleaning: the angle adjusting mechanism acts to adjust the opening angle of the air door, so that the entering air flow is directly blown to the surface of the filter screen, and condensed water in the foreign matters is blown to two ends of the filter screen and then transferred to the liquid storage cavity through the liquid absorption structure to be discharged;
step 400, judging a result: after the foreign matter is cleaned and operated for a period of time T, if the air volume monitored by the air volume monitoring element is recovered to a normal state, the angle adjusting mechanism continues to act to open the air door to a maximum state, and the air door is operated at a maximum wind gear; if the air quantity monitored by the air quantity monitoring element is not improved, an alarm notice is sent to a user through the alarm module so as to close the fresh air system for checking.
The length of the operation time T is more than or equal to 1 minute and less than or equal to 10 minutes.
The working principle of the clearing component of the invention is as follows: as shown in FIG. 6, the change condition of the fresh air volume is judged by monitoring the static pressure at the inlet of the fresh air inlet cavity. When the fresh air function is operated in plum rain weather, if the static pressure at the inlet of the fresh air inlet cavity is increased, the fresh air quantity is reduced to some extent, and then the angle of the fresh air door is adjusted, so that the high-speed fresh air flow flowing out of the fresh air pipe impacts the surface of the air filter screen to achieve the function of cleaning the surface of the air filter screen. Meanwhile, a water absorption rod is arranged in an air inlet cavity of the fresh air system, and condensed water which is impacted to the edge is transferred by virtue of a capillary effect. When the control system monitors that the pressure value at the inlet of the air inlet cavity begins to drop, and when the pressure value drops to a reasonable range, the state of the fresh air door is changed into a completely open state, and at the moment, the pressure value at the inlet of the air inlet cavity can further drop due to the further increase of the fresh air volume. It should be noted that the reasonable range of the inlet pressure value of the air inlet chamber is obtained by experimental tests.
And the subsequent control system continuously monitors the change of the pressure value at the inlet of the fresh air inlet cavity and judges whether the angle of the fresh air door needs to be adjusted.
After the mode of cleaning is opened to adjustment new trend air door angle, after a period of time T, the pressure value of new trend air inlet chamber entrance still does not descend, then this control system sends out the trouble and reminds, reminds the user whether the inspection needs to change airstrainer or new trend air inlet mouth of pipe by the foreign matter jam.
The set value of the time T elapsed after the cleaning mode is turned on is 1 minute to 10 minutes.
It should be noted that "inward" is a direction toward the center of the accommodating space, and "outward" is a direction away from the center of the accommodating space.

Claims (15)

1. A clearing component is characterized by comprising an air door and an air quantity monitoring element which are arranged at an inlet of an air inlet cavity, and an angle adjusting mechanism which is in transmission connection with the air door to control the opening angle of the air door; when the air volume monitoring element monitors that the air volume becomes small, the opening angle of the air door is controlled to enable the entering fresh air to be directly blown to the component to be cleaned, and the air inlet airflow is utilized to clean the choke foreign matters on the component to be cleaned.
2. The dissipating assembly of claim 1, wherein the recliner mechanism includes a shaft and a power source connected to the shaft.
3. The dissipating assembly of claim 1, wherein the air volume monitoring element comprises a static pressure gauge.
4. The cleaning assembly according to claim 1, further comprising a liquid storage cavity and a liquid suction structure, wherein the liquid storage cavity is arranged below the air inlet cavity, a water outlet is arranged at the bottom of the liquid storage cavity, one end of the liquid suction structure is connected with a component to be cleaned, and the other end of the liquid suction structure is communicated with the liquid storage cavity.
5. A dissipating assembly according to claim 4, wherein the wicking structure is at least one in number and is disposed inwardly in sequence along both ends of the member to be dissipated.
6. The dissipating assembly of claim 4, wherein said wicking structure includes a capillary wicking bar and at least one tentacle disposed on said capillary wicking bar, said tentacle abutting a surface of the component to be dissipated.
7. The dissipating assembly of claim 4, further comprising a porous baffle and a desiccant, said porous baffle disposed within said reservoir; the drying agent is placed on one side of the porous baffle far away from the water outlet.
8. The dissipating assembly of claim 7, wherein the perforated barrier is inclined with a top portion connected to the top wall of the reservoir and a bottom portion connected to the bottom wall of the reservoir.
9. The dissipating assembly of claim 1, further comprising an alarm module electrically connected to the air volume monitoring element.
10. The dissipating assembly of claim 9, further comprising a control module electrically connected to the recliner mechanism, the air volume monitoring element, and the alarm module.
11. A fresh air system comprising an air inlet chamber, an inlet and an outlet disposed at either end of the air inlet chamber, the outlet being provided with a filter screen, and a clean-out assembly according to any one of claims 1 to 10 disposed at the inlet.
12. The fresh air system of claim 11 wherein the inlet and the outlet are disposed at a 90 degree included angle.
13. An air conditioner comprising a fresh air system as claimed in any one of claims 11 to 12.
14. A method of removing a wind-blocking foreign matter from a fresh air system according to any one of claims 11 to 12, comprising the steps of:
step 100, starting: starting the fresh air system, opening the air door to the maximum angle, operating at the maximum wind gear, and continuing to a stable state;
step 200, wind resistance judgment: the air quantity monitoring element acquires the static pressure value at the inlet of the air inlet cavity in real time, and when the acquired static pressure value is increased, the amount of the wind-blocking foreign matters at the filter screen is too large, and the foreign matters need to be cleaned;
step 300, foreign matter cleaning: the angle adjusting mechanism acts to adjust the opening angle of the air door, so that the entering air flow is directly blown to the surface of the filter screen, and condensed water in the foreign matters is blown to two ends of the filter screen and then transferred to the liquid storage cavity through the liquid absorption structure to be discharged;
step 400, judging a result: after the foreign matter is cleaned and operated for a period of time T, if the air volume monitored by the air volume monitoring element is recovered to a normal state, the angle adjusting mechanism continues to act to open the air door to a maximum state, and the air door is operated at a maximum wind gear; if the air quantity monitored by the air quantity monitoring element is not improved, an alarm notice is sent to a user through the alarm module so as to close the fresh air system for checking.
15. The method of claim 14, wherein the period of operation T is 1 minute ≦ Y ≦ 10 minutes.
