Description

Technical Field

[0001] The utility model relates to the technical field of general mechanical equipment manufacturing, and more specifically to a fresh air ventilator with bidirectional flow and high-efficiency purification. Background Art

[0002] The fresh air ventilator is designed and developed based on the principle that a "fresh air flow field" will be formed in the closed room by supplying air on one side and induced air on the other side. It relies on mechanical air supply and induced air to force the formation of a fresh air flow field in the system.

[0003] For example, a two-way flow fresh air fan disclosed in announcement number CN214249810U includes: a casing, a fan, a first fan bracket, a second fan bracket, a first wind shield, a second wind shield, a third wind shield, a heat exchange core and a filter are arranged inside the casing, an exhaust port and a fresh air port are arranged on one side of the casing, and an air supply port and a return air port are arranged on the other side, a filter is fixed between the second wind shield and the lower casing of the casing, a filter is also fixed between the third wind shield and the lower casing of the casing, and the heat exchange core is fixed between the first fan bracket fixing plate, the second fan bracket fixing plate, the inclined plate of the second wind shield, the inclined plate of the third wind shield and the lower casing of the casing. The two-way flow fresh air fan provided by the utility model adopts a configuration in which two fans are at right angles and the heat exchange core is placed therein, so that the overall body is more compact, the double fans have a large air volume, and occupy less space when in use, the fixed position of the heat exchange core is easy to disassemble, which is convenient for replacing the filter element, the heat cycle is convenient, and energy and electricity are saved.

[0004] It can be seen from the above-mentioned public scheme that the current fresh air ventilator casing does not have sound absorption and sound insulation effects. During use, the fresh air ventilator will generate relatively loud noise, which is transmitted to the outside of the casing through the casing, thus bringing adverse effects. At the same time, the air inlet and outlet pipes of the fresh air ventilator are not easy to move and extend, thus affecting the connection with the external connecting pipes. Utility Model Content
