The electric rotary valve closes the outlet of the second group of heat exchange air flow passages, and opens a gap between the heat exchange system and the corresponding inner wall of the housing at the position where the electric rotary valve is located, so that the indoor air is in the Under the action of the exhaust fan, the heat exchange system is bypassed after entering the casing through the air outlet, and is discharged by the exhaust fan through the gap between the heat exchange system and the corresponding inner wall of the casing. .

The heat recovery air blower according to claim 4, wherein the air extracting port comprises a first group of air extracting ports and a second group of air extracting ports, and the first group of air extracting ports and the second group of heat exchange air streams Road connectivity;

The electric rotary valve is completely snoring the second group of heat exchange air flow path outlets, and the indoor air enters the casing from the first group of air extraction ports under the action of the exhaust fan. Passing through the second set of heat exchange air flow passages for heat exchange with outdoor air passing through the first heat exchange air flow passage;

The electric rotary valve closes the second set of heat exchange air flow path outlets, and the indoor air enters the casing from the second group of air extraction ports and bypasses the heat exchange system under the action of the exhaust fan. The gap between the heat exchange system and the corresponding inner wall of the casing is discharged to the outside by the air blower.

[Claim 7] The heat recovery new fan according to claim 4, wherein the air outlet comprises a first group of air outlets and a second group of air outlets, the first group of air outlets and the second Group heat exchange air flow passages are connected;

a sliding valve associated with the electric rotary valve is disposed at the second group of air outlets, and the electric rotary valve completely slams the second group of heat exchange air flow outlets to drive the sliding valve to completely close The second group of air outlets allow indoor air to enter the casing from the first group of air extracting ports, and pass through the second group of heat exchange air flow passages Heat exchange of outdoor air of a group of heat exchange air flow passages, the electric rotary valve closing the second group of heat exchange air flow passage outlets, driving the sliding valve to snore the second group of air outlets, so that the indoor Under the action of the exhaust fan, the air enters the casing from the second group of air extracting openings, and is directly discharged by the exhaust fan directly after being exhausted from the heat exchange system.

[Claim 8] The heat recovery new fan according to claim 4, wherein the air outlet comprises a group of air outlets, and the group of air outlets communicate with the second group of heat exchange air channels; a sliding valve associated with the electric rotary valve is disposed at the air outlet; the electric rotary valve is fully snoring the second group of heat exchange air flow outlets, and the sliding valve is closed to be adjacent to the second group Heat-exchange the portion of the air outlet of the air flow path outlet, so that the indoor air enters the casing from the air extracting port under the action of the air blowing fan, passes through the second group of heat exchange air flow paths, and passes through the Exchanging outdoor air of the first group of heat exchange air passages for heat exchange;

The electric rotary valve closes the outlet of the second group of heat exchange air flow passages, and drives the same Sliding valve slamming the portion of the air outlet adjacent to the outlet of the second group of heat exchange air passages, so that indoor air is driven by the exhaust fan, and entering the housing from the air outlet to avoid the After the heat exchange system, it is directly discharged to the outside by the exhaust fan.
