The invention provides a new and old air switching device of a single fan, which provides two functions of indoor fresh air supply and outdoor old air exhaust for a user, and the user can select one of two modes according to a preset program instruction. When a user selects an indoor fresh air supply mode, the program control motor adjusts the air inlet/outlet valve to the corresponding position, so that the fresh air supply flow path is opened, the old air exhaust flow path is closed, the fan operates to extract outdoor air, the air firstly flows in through the ventilation pipe, is filtered by the filter screen and is then supplied to the indoor space by the fan, and the air supplied to the indoor space is fresh air. When the user selects the outdoor exhaust old air mode, the program control motor adjusts the air inlet/outlet valve to the corresponding position, so that the exhaust old air flow path is opened, the fresh air supply flow path is closed, and when the old air is exhausted outdoors, the indoor air is directly exhausted into the air exchange pipe and flows out to the outdoor environment after being pumped by the fan.
This device structural design is exquisite, compact structure, and space utilization is high, utilizes advance/air-out valve, opens or the closed business turn over wind runner that corresponds, so only need single fan can realize sending new trend and exhaust old air (blowdown wind), two fans of the air exhaust and air inlet demand of having avoided conventional new trend device. Meanwhile, the filtering structure is arranged on the fresh air supply flow path, the old air exhaust flow path does not pass through the filtering structure, the air exhaust resistance is reduced, the air quantity of the fan under the air exhaust working condition can be obviously improved, and indoor dirty air is effectively exhausted. Meanwhile, fresh air supply and old air exhaust share one ventilation pipeline, so that the hole punching area or the hole punching quantity of the wall body is reduced.
The invention provides a new and old air switching device of a single fan, which provides two functions of indoor new air supply and outdoor old air exhaust for users, and the users can select different operation modes according to the requirements of the users, wherein the selectable modes are an indoor new air supply mode and an outdoor old air exhaust mode. When a user selects an indoor fresh air supply mode, the air inlet conversion first valve (the first baffle 31) and the air outlet conversion second valve (the second baffle 32) are adjusted to the positions shown in fig. 3, at the moment, the indoor air outlet 11 is opened, the indoor air inlet 12 is closed, the fresh air flow path is opened, the fan rotates to draw outdoor air from the outdoor connecting port, at the moment, air flow firstly flows into the air exchange cavity from the air exchange pipe connected with the outdoor, enters the air inlet flow path after being filtered by the fresh air filter 40 (which can be a filter screen), and is then pressurized in the fan volute 14 through the fan impeller 20 and then is sent into the indoor through the indoor air outlet 11. The fresh air introduced into the room is filtered, so that the fresh air flowing into the room is clean air.
When a user selects an outdoor old air discharging mode, the air inlet conversion first valve and the second valve are adjusted to the positions shown in the figure 2, the indoor air outlet 11 is closed, the indoor air inlet 12 is opened, the air discharging flow path is opened, the fan rotates to draw indoor dirty air from the indoor air inlet 12, the air flow firstly enters the air inlet flow channel, then is pressurized by the fan and flows out of the air discharging flow channel, and then enters the air exchanging cavity and is discharged to the outside from the outdoor connecting port. The old air discharged outdoors does not need to pass through a filter screen structure, and the resistance of the air channel flow channel is remarkably reduced, so that the air exhaust volume of the fan under the same power is remarkably larger than that under a fresh air mode, and the dirty air is effectively discharged to the outdoor environment.
After the function of the device is started, the fan operates, the air inlet/outlet flow channel valve is reset to the position shown in figure 3, the indoor fresh air supply mode is entered by default, and a logic flow chart is shown in figure 5. And then the position of the air inlet/outlet flow channel valve is changed according to different requirements of users, so that the switching of indoor fresh air supply and outdoor old air exhaust under a single fan is realized, and logic flow charts are shown in fig. 6 and 7.
Adopt the new trend device that this embodiment provided, can realize the new and old wind auto-change over device of single fan, the user can send new trend or outdoor row of old wind according to function program selection indoor, and device structural design is exquisite, compact structure, and space utilization is high, and usable single fan realizes indoor new trend or outdoor row of old wind of sending, has avoided two fans of conventional new trend device air exhaust and air inlet demand. Meanwhile, the fresh air sent to the indoor is sent in after being filtered, the old air exhausted to the outdoor does not pass through a filtering structure, the air exhaust resistance is reduced, the air exhaust quantity is obviously improved, and the indoor dirty air is guaranteed to be exhausted. The fresh air supply and the old air exhaust share one ventilation pipeline, so that the hole punching area or the hole punching quantity of the wall body is reduced.
The fresh air and old air switching device of the single fan of the air conditioner can also be used in fresh air fans, air purifiers, fans and other air supply equipment which can exchange air with the outside; by utilizing the switching of the air inlet channel and the air outlet channel, the single fan can respectively realize two functions of supplying fresh air and exhausting old air.
