Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings.
According to one embodiment of the application, a fan device for a fresh air system is provided, and fig. 1 shows an internal structural schematic diagram of the fan device. FIG. 2 illustrates a perspective view of an exemplary fan apparatus according to embodiments of the present application. As shown in fig. 1 and 2, a fan apparatus according to an embodiment of the present application includes:
a housing 10 enclosing a cavity;
the filtering module is provided with a filtering net I and an energy exchanging device J, is positioned inside the shell 10, and divides a cavity enclosed by the shell 10 into a first cavity C1 and a second cavity C2;
the exhaust fan E is positioned in the first cavity C1;
the fresh air fan F is positioned in the second cavity C2;
an outdoor exhaust outlet 11 and an outdoor fresh air inlet 12 are arranged in the part of the shell 10 corresponding to the first cavity C1, the outdoor exhaust outlet 11 is communicated with an air outlet E1 of an exhaust fan E through an exhaust sub-cavity S1, and the outdoor fresh air inlet 12 is communicated with a filtering module through a fresh air sub-cavity S2;
an indoor fresh air outlet 13 and an indoor exhaust air inlet 14, the indoor fresh air outlet 13 and the indoor exhaust air inlet 14 being provided in a portion of the casing 10 corresponding to the second cavity C2.
Wherein, the air exhaust sub-cavity S1 and the fresh air sub-cavity S2 are selectively communicated through an air valve 20. The outdoor side of the outdoor fresh air inlet 12 is provided with an air cover 121 for adhering dirt such as dust and catkin thereto and preventing the dirt from entering the fan device through the outdoor fresh air inlet 12.
In the fresh air mode, as shown in fig. 1 and fig. 2 (at this time, the air valve 20 is in a closed state, and the exhaust air sub-cavity S1 is not communicated with the fresh air sub-cavity S2), under the action of the fresh air fan F, outdoor fresh air is introduced into the fan device through the outdoor fresh air inlet 12, and is filtered, heat-exchanged and the like at the filtering module, and then is discharged into the room through the indoor fresh air outlet 13, so as to provide fresh air into the room; the dirty air in the room is introduced into the fan apparatus through the indoor discharge air inlet 14 by the discharge fan E in the fan apparatus, and is discharged to the outside through the outdoor discharge air outlet 11 after being subjected to heat exchange or the like at the energy exchanging device J.
Fig. 4 illustrates a perspective view of an exemplary fan apparatus in a hood cleaning mode according to embodiments of the present application. In the hood cleaning mode, as shown in fig. 4, the air valve 20 is opened to place the exhaust air sub-chamber S1 in air communication with the fresh air sub-chamber S2 while causing the fresh air fan F to be turned off and the exhaust air fan E to be turned on. At this time, the air discharged from the air outlet E1 of the exhaust fan E is discharged to the outside of the room via the exhaust sub-chamber S1, the air valve 20, the fresh air sub-chamber S2, and the outdoor fresh air inlet 12 (the air flow path is shown by the arrows in fig. 4).
It can be seen that in the hood cleaning mode, the air flow direction at the outdoor fresh air inlet 12 is reversed, i.e. opposite to its flow direction in the fresh air mode. The air flowing in the reverse direction can easily blow off dirt such as dust and catkin adhered to the fan housing 121 (e.g., on a filter screen of the fan housing), thereby achieving a fan housing cleaning function.
FIG. 3 illustrates a schematic structural view of an exemplary damper 20 according to embodiments of the present application. The damper 20 includes a pivot 21 and a flapper member 22, the flapper member 22 being rotatable about the pivot 20 between a first position and a second position. When the baffle member 22 is in the first position, the baffle member 22 closes the opening between the exhaust air sub-chamber S1 and the new air sub-chamber S2, thereby preventing communication between the exhaust air sub-chamber S1 and the new air sub-chamber S2. When the baffle member 22 is in the second position, the baffle member 22 opens the opening between the exhaust air sub-chamber S1 and the new air sub-chamber S2, allowing communication between the exhaust air sub-chamber S1 and the new air sub-chamber S2.
Preferably, when the baffle member is in the second position, the baffle member 22 opens the opening between the exhaust air sub-chamber S1 and the fresh air sub-chamber S2 and closes the outdoor exhaust air outlet 11 (as shown in fig. 4, the baffle member 22 blocks the outdoor exhaust air outlet 11) to increase the amount of air flowing out of the outdoor fresh air inlet 12.
According to other embodiments of the present invention, the air valve 20 may also adopt other forms of structures as long as the air exhaust sub-cavity S1 can be selectively communicated with the new air sub-cavity S2.
According to other embodiments of the invention, the exhaust air sub-cavity S1 and the fresh air sub-cavity S2 are preferably adjacent, for example separated by a partition in which the damper 20 is located, as in the configuration shown in fig. 1 and 2.
According to other embodiments of the present invention, the positional relationship between the exhaust air sub-cavity S1 and the new air sub-cavity S2 is not limited to the adjacent relationship shown in fig. 1 and 2. For example, the exhaust air cavity S1 and the fresh air cavity S2 are connected by an air passage in which the air valve 20 is located.
According to the fan equipment of an embodiment of this application, still include mode selection unit and control unit. The mode selection unit is used for selecting the working mode of the fan device. The control unit controls the air valve 20, the fresh air fan F, and the exhaust air fan E in response to the selection result of the mode selection unit.
When the mode selection unit selects the fresh air mode, the control unit controls the air valve 20 to enable the air exhaust sub-cavity S1 to be not communicated with the fresh air sub-cavity S2, and the fresh air fan F and the air exhaust fan E are started.
When the mode selection unit selects the fan housing cleaning mode, the control unit controls the air valve 20 to enable the exhaust air sub-cavity S1 to be communicated with the new air sub-cavity S2, and the new air fan F is closed and the exhaust air fan E is opened.
In the hood cleaning mode, air discharged from the air outlet E1 of the exhaust fan E is discharged to the outside via the exhaust sub-chamber S1, the air valve 20, the fresh sub-chamber S2, and the outdoor fresh air inlet 12.
In the fan equipment disclosed in this application, can have fan housing washing mode. In the fan housing cleaning mode, air can reversely flow through the outdoor fresh air inlet, so that dust, catkin and other dirt adhered to the fan housing can be easily blown off, and the fan housing cleaning function is realized.
It should be understood that although the present description has been described in terms of various embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and those skilled in the art will recognize that the embodiments described herein may be combined as suitable to form other embodiments, as will be appreciated by those skilled in the art.
The above description is only illustrative of the present invention and is not intended to limit the scope of the present invention. Any equivalent alterations, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of this application shall fall within the scope of this application.
