The invention provides a ventilation device and an air conditioner comprising the ventilation device. The ventilation device comprises a shell, a reversing valve, an air suction sealed chamber, an air suction motor and an air inlet switch mechanism, wherein a ventilation chamber is formed in the shell; the reversing valve is provided with a first reversing valve opening, a second reversing valve opening and a third reversing valve opening; the first reversing valve opening and the second reversing valve opening are selectively communicated with the third reversing valve opening; the air suction sealed chamber is provided with an air outlet channel and a filter opening which is provided with a filter net; the air suction motor is provided with an air suction port and an air outlet; an air inlet is also formed in the air suction sealed chamber; the air inlet switch mechanism is arranged in the shell and comprises a baffle which is arranged at the air inlet pivotally; the baffle is connected with the reversing valve through a connecting rod transmission mechanism; the reversing valve opens or closes the air inlet by the baffle which is driven by the connecting rod transmission mechanism. By the ventilation device and the air conditioner comprising the ventilation device, bidirectional ventilation can be realized, and meanwhile, a one-way filter function can be realized, so that unnecessary using states of the filter net are reduced, and the service life of the filter net is prolonged.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to a ventilation device and an air conditioner including the ventilation device. Background technique [0002] The ventilation equipment of the traditional air conditioner can realize indoor and outdoor two-way ventilation, that is, the indoor air is discharged to the outside or the outdoor air is sucked into the room through the ventilation equipment. In the prior art, both of these two ventilation methods require the circulating air to pass through the filter screen. However, filtering the indoor air and discharging it to the outside will cause a waste of resources. At the same time, due to the relatively short service life of the filter, it must be replaced after a period of frequent use, and the filtered and discharged outdoor air also increases the burden on the filter. , so that the service life of the filter is reduced. Therefore, the ideal state is that when the air is suck...
