FIG. 1 is a disassembled schematic view of a shading assembly according to an exemplary embodiment. As shown in fig. 1, the shielding assembly 100 provided in the embodiment of the present disclosure is used for being connected to an outdoor vent 210 of a ventilation duct 200, and specifically includes: a connecting portion 110 and a shielding portion 120. The connecting portion 110 is used to connect with the ventilation duct 200, and the blocking portion 120 is connected with a portion of the connecting portion 110 away from the ventilation duct 200.

Alternatively, the inner hollow of the connection part 110 is formed as a cavity 111. The cavity 111 has a first opening 111a and a second opening 111b at opposite ends thereof. The connecting portion 110 further includes a sidewall 112, and the sidewall 112 connects the first opening 111a and the second opening 111b, respectively, and is disposed around the cavity 111. The second opening 111a is connected to the ventilation duct 200, and the connection portion 110 is provided with a ventilation hole 113 communicating with the cavity 111.

When the connecting portion 110 is connected to the ventilation duct 200, the cavity 111 communicates with the ventilation duct 200. At this time, the airflow outside the shielding member 100 enters the ventilation duct 200 through the ventilation hole 113 and the cavity 111 in order.

In this way, the portion of the connecting portion 110 except the ventilation hole 113 has a shielding effect, and the connecting portion 110 can prevent fresh air caused by outdoor wind from flowing backward into the ventilation duct 200 besides shielding impurities. Moreover, the condensation phenomenon in the ventilation duct 200 caused by the backflow of cold air in low-temperature and strong-wind weather is effectively avoided through the connecting part 110.

The shielding portion 120 is disposed at the first opening 111a and connected to the sidewall 112. Also, the size of the shielding portion 120 is larger than the size of the first opening 111a to shield the first opening 111 a. In the use state of the shutter assembly, the first opening 111a of the connecting portion 110 is located above the second opening 111 b. In this way, the shielding portion 120 plays a role of shielding solid impurities, rain water, snow water, and the like from entering the ventilation duct 200. Optionally, the edge of the shielding portion 120 exceeds the connecting portion 110, and at this time, rainwater or snow water directly slides along the edge of the shielding portion 120, so as to prevent the rainwater or snow water from flowing along the connecting portion 110 and further flowing back into the ventilation duct 200 through the ventilation hole 113.

In the disclosed embodiment, the vent 113 has various implementations, which are described below with reference to the drawings.

Fig. 2 is a schematic structural diagram of a connection portion shown according to an exemplary embodiment. As shown in fig. 2, the first opening 111a of the connecting portion 110 has a first edge 110a, and the second opening 111b has a second edge 110 b. Also, a partial depression of the first edge 110a and/or the second edge 110b forms the vent hole 113 (only shown in fig. 2 as having a partial depression at the first edge 110 a).

After the shutter assembly 100 is connected to the ventilation duct 200 (not shown in fig. 2), the first edge 110a and the second edge 110b are upper and lower edges of the connection portion 110, respectively. At this time, since the first edge 110a and/or the second edge 110b are/is recessed, a gap, that is, the vent hole 113, is formed between the connection part 110 and the shielding part 120 (not shown in fig. 2), and/or between the connection part 110 and an edge of the ventilation duct 200. In this way, the shielding effect of the connecting part 110 is enhanced, and the backflow of fresh air or cold air is avoided.

Fig. 3 is a schematic structural diagram of a connection portion shown according to another exemplary embodiment. As shown in fig. 3, the first opening 111a of the connecting portion 110 has a first edge 110a, and the second opening 111b has a second edge 110 b. The vent hole 113 is disposed on the sidewall 112 between the first edge 110a and the second edge 110 b.

Alternatively, as shown in fig. 3, the vent holes 113 are arranged along the circumferential direction of the cavity 111, or the vent holes 113 are arranged along the axial direction of the cavity 111, or the vent holes 113 are uniformly arranged on the connecting portion 110. Here, the radial sectional shape of the vent hole 113 is not particularly limited, and is, for example, circular, elliptical, square, or the like. In this way, the connection portion 110 forms a screen-like structure, in which case the flow rate of the air flow passing through the connection portion 110 can be increased.

Fig. 4 is a schematic structural diagram of a connection portion shown according to another exemplary embodiment. As shown in fig. 4, a first connecting structure 114 is disposed on the connecting portion 110, and the first connecting structure 114 is used for detachably connecting with the ventilation duct 200. In this manner, mounting and dismounting of the shutter assembly 100 is facilitated, reducing assembly maintenance costs.

It should be noted that the first connecting structure 114 in fig. 4 is specifically a threaded structure, but the first connecting structure 114 may also be other connecting structures, such as a mounting hole for engaging a screw or a bolt, or a mounting key for engaging a mounting groove.

FIG. 5 is a disassembled structural schematic view of a shading assembly according to another exemplary embodiment. As shown in fig. 5, the sidewall 112 of the connection portion 110 is formed in a funnel shape gradually decreasing from the first opening 111a to the second opening 111 b.

At this time, the liquid drops (such as rain, snow, or condensation) attached to the side wall 112 are more likely to drop directly under the action of gravity, and are difficult to continuously slide along the connecting portion 110, so as to prevent the liquid from flowing backward to the ventilation duct 200 through the ventilation holes 113. Optionally, the angle of the connecting portion 110 to the vertical direction is 10 ° to 70 °.

Also, the shielding part 120 forms a funnel shape gradually expanding toward the connection part 110. At this time, the outer side surface of the shielding portion 120 is inclined downward. In this way, rain and snow, foreign substances, or the like are less likely to adhere to the shielding portion 120, and the protection of the ventilation duct 200 by the shielding member 100 is further enhanced.

In summary, the shielding assembly 100 provided in the embodiment of the present disclosure provides a vent hole 113 on the connecting portion 110, so that an airflow sequentially passes through the vent hole 113 and one end to enter the ventilation duct 200. The part that does not set up ventilation hole 113 through connecting portion 110 has played the effect of sheltering from, effectively shelters from impurity entering air pipe to the problem that the new trend flows backward and the refrigerated air flows backward leads to the condensation has been solved.

Also, in the related art, the outdoor vent 210 of the ventilation duct 200 is disposed downward to avoid clogging by debris. However, this causes the airflow to enter the ventilation duct only through the outdoor vent 210 from the bottom up, and there is a large airflow resistance. However, the shielding assembly 100 provided in the embodiment of the present disclosure is adopted, so that the outdoor vent 210 of the ventilation duct 200 may be disposed upward, and the vent hole 113 is opened on the connection portion 110.

Based on the shielding assembly, the embodiment of the disclosure further provides an air conditioner. Fig. 6 is a schematic diagram illustrating a structure of an air conditioner according to an exemplary embodiment. As shown in fig. 6, the air conditioner includes the shielding assembly 100, the ventilation duct 200, and the indoor unit 600 installed and installed indoors, which are provided as described above. Among them, the ventilation duct 200 includes an outdoor vent 210 located outdoors and an indoor vent located indoors. Wherein the opening of the outdoor ventilation opening 210 is disposed upward. Also, the ventilation duct 200 is also communicated with the indoor unit 600 to provide airflow to the indoor unit 600. The connection portion 110 of the barrier assembly 100 is connected to the outdoor vent 210.

When the air conditioner is used, the airflow passes through the ventilation hole 113 of the connection part 110, the cavity 111 formed by the connection part 110, and the outdoor ventilation opening 210 in sequence, enters the ventilation duct 200, and then enters the indoor space.

The air conditioner provided by the embodiment of the disclosure effectively shields outdoor impurities from entering the ventilation pipeline 200 by shielding the component 100, avoids the problem of backflow of fresh air and the problem of condensation caused by backflow of cold air by shielding the component 100, and effectively ensures smooth operation of the air conditioner. Also, the outdoor vent 210 of the ventilation duct 200 may be disposed upward by using the shielding member 100.

Fig. 7 is a schematic structural view of an air conditioner according to another exemplary embodiment. As shown in fig. 7, the air conditioner further includes: a controller 500, and a duct fan 300 disposed inside the ventilation duct 200. The controller 500 is used for controlling the pipeline fan 300 to start, stop and turn.

The duct fan 300 is controlled to rotate in the forward direction to guide the airflow outside the outdoor ventilation opening 210 into the ventilation duct 200, and then the airflow is introduced into the indoor unit 600 through the indoor ventilation opening, so that the fresh air function of the air conditioner is realized. By controlling the reverse rotation of the duct fan 300, the airflow in the ventilation duct 200 is guided to the outdoor ventilation opening 210, so that the airflow acts on the blocking object on the outdoor ventilation opening 210, thereby achieving the effects of flushing and oscillation, and realizing the blockage clearing effect. Wherein the duct fan 300 is operated in a constant speed manner or in a variable speed manner.

The blockage clearing function of the air conditioner has various example realization modes:

illustratively, the pipe blower 300 is activated at preset time intervals (e.g., one week, two weeks, one month, etc.) to perform the clearing work.

Illustratively, the blockage removal is performed by the duct fan 300 after each use of the fresh air function of the air conditioner.

Illustratively, the air conditioner outputs prompt information to prompt a user to manually operate and start the pipeline fan 300 for clearing the blockage. For example, the prompt message (for example, output prompt text or icon) is output on the display interface of the air conditioner, or the prompt message is output in the terminal APP which is in communication connection with the air conditioner.

Optionally, the air conditioner further comprises: and the pressure monitoring assembly 400 is arranged inside the ventilation pipeline 200 and used for monitoring the air pressure in the ventilation pipeline 200.

The pressure monitoring assembly 400 is used to detect absolute air pressure or relative air pressure within the ventilation duct 200. The absolute air pressure is the actual air pressure within the ventilation duct 200. The relative air pressure is the difference between the actual air pressure in the ventilation duct 200 before and during the operation of the fresh air function of the air conditioner. The monitoring of the relative air pressure can avoid pipeline blockage caused by extrusion of a blockage in the pipeline due to weather factors (such as spring poplar catkins) and the like in the pipeline.

Optionally, the pressure monitoring component 400 is configured to obtain the monitored value after the fresh air function starts to operate for a set time period (e.g., 5s, 10s, 15s, etc.). After the set time, the fan operating the fresh air function works stably, the data monitored by the pressure monitoring assembly 400 is not affected by the operation stability of the fan, and the air pressure condition in the ventilation pipeline 200 is reflected faithfully.

The controller 500 is electrically connected to the pressure monitoring device 400, and is configured to control the operation of the duct fan 300 according to a monitoring value of the pressure monitoring device. For example, when the monitoring value is greater than or equal to the preset threshold value, the controller 500 starts the duct fan 300 to rotate in the reverse direction, so that the airflow flows from the inside of the ventilation duct to the outlet end communicated with the outside, and the blockage located in the blocking assembly is blown out to perform blockage clearing work. When the monitored value is greater than or equal to the preset threshold value, the controller 500 indicates that the air pressure in the ventilation duct 200 is relatively high, and the ventilation duct 200 needs to be cleared as soon as possible.

In summary, the air conditioner provided by the embodiment of the disclosure has better operation stability and intelligence degree. Specifically, the whole system running stability improved by the shielding assembly 100 is improved, the blockage cleaning function of the ventilation pipeline 200 is realized through the pipeline fan 300, the situation that the blockage cleaning is needed to be carried out on the ventilation pipeline 200 is accurately identified through the pressure monitoring assembly 400 and the controller 500, and the intelligent level of the air conditioner is improved.
