Problems solved by technology
But in winter and summer, even if the outdoor air enters the room through the heat exchanger, it will have a great impact on the indoor temperature, which cannot improve the living comfort.
[0004] Among the existing fresh air fans, there are still multiple independent valves set in different areas to control the flow or blockage of different channels respectively, but this does not solve the problem that the indoor temperature is greatly affected in winter and summer, and multiple independent valves The valves need to be set separately, not only the structure is complicated, but also multiple areas for placing the valves may be set, which takes up a lot of space
In some new fans, the valve is set in a cavity, and the cavity itself takes up space, and the vertical setting between the two valves takes up even more space.

Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] Such as Figure 1~Figure 7 Shown: a fresh air fan with multiple operating modes, including a casing 1, an old air exhaust system and a fresh air system arranged in the casing, and a heat exchanger 2 arranged between the old air exhaust system and the fresh air system The old air exhaust system includes an independently arranged old air suction area 3 and an old air discharge area 4; the fresh air system includes an independently provided fresh air suction area 5 and a fresh air discharge area 6, and the fresh air discharge area 6 is provided with a fresh air blower 61 and a high-efficiency Filter 62. The old air suction area 3 includes an exhaust air inlet 31; a valve frame 7 is provided above the heat exchanger 1 and the exhaust air inlet 31 and below the fresh air fan 61, and a valve plate 71 and a louver 72 are arranged in ...

The invention provides a fresh air ventilator with multiple operation modes. The fresh air ventilator comprises a casing, an old air exhaust system, a fresh air system and a heat exchanger, wherein the old air exhaust system and the fresh air system are arranged in the casing; the heat exchanger is arranged between the old air exhaust system and the fresh air system; the old air exhaust system comprises an old air suction area and an old air exhaust area which are arranged independently; the fresh air system comprises a fresh air suction area and a fresh air exhaust area which are arranged independently; a fresh air fan and at least one high efficiency filter are arranged in the fresh air exhaust area; the old air suction area comprises an air exhaust inlet formed in the side surface of the casing; the air exhaust inlet is formed in a projection plane of an old air inlet side of the heat exchanger on the casing; a valve buckle is arranged above the heat exchanger and the air exhaust inlet and below the fresh air exhaust area; a baffle is arranged between the valve buckle and the heat exchanger; a valve plate and a louver are horizontally arranged in the valve buckle; and a valve linkage mechanism is connected between the valve plate and the louver. The fresh air ventilator has the advantages that on one hand, the space utilization rate can be greatly improved, and the size of the whole fresh air ventilator is reduced; and on the other hand, the habitant comfortability is high, the energy-saving effect is remarkable, and the operation modes are diversified.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to a fresh fan with multiple operating modes. Background technique [0002] Existing indoors generally purify the air in the room by installing a fresh air blower. When the fresh air blower works, the outdoor fresh air can be sucked into the room, and the old indoor air can be discharged to the outside. Due to the different temperatures in spring, summer, autumn and winter, especially the large temperature difference between summer and winter, it is an urgent technical problem to meet the indoor temperature suitability. [0003] In order to solve the above problems, the existing fresh air fans usually set up a bypass area. In summer and winter, the bypass valve in the bypass area is disconnected, and the fresh air must pass through the heat exchanger for cooling or heating; In spring and autumn, the bypass valve is automatically opened, and the fresh air in the fresh air s...
