As shown in fig. 1, in the fresh air conditioner provided by the invention, a fresh air outlet 2 is arranged at a main air outlet 1 of an indoor unit, and a fresh air duct 3 related to the fresh air outlet 2 is connected with indoor air and outdoor air; when the fresh air conditioner operates, a flow velocity difference is formed between circulating air blown out from the main air outlet 1 of the indoor unit and outdoor air led in from the fresh air outlet 2; the flow velocity difference accelerates the flow velocity of the outdoor air introduced at the fresh air outlet 2.
The existing fresh air conditioner is generally characterized in that a fresh air outlet is formed in a non-main air outlet of an indoor unit, outdoor air is blown into a room from the fresh air outlet through a fresh air fan, so that the indoor air pressure is increased, and the fresh air effect is poor.
In order to overcome the defect, the fresh air conditioner provided by the invention has the advantages that the fresh air outlet is arranged at the main air outlet of the indoor unit, so that the fresh air outlet can be surrounded by the circulating air blown out from the main air outlet of the indoor unit under the condition of running the fresh air conditioner, and further, the flow velocity difference is formed between the circulating air and the outdoor air led in at the fresh air outlet, and the flow velocity difference can accelerate the flow velocity of the outdoor air led in at the fresh air outlet.
The fresh air conditioner provided by the invention has the advantages that the circulating air blown out from the main air outlet 1 of the indoor unit is utilized to surround the fresh air outlet 2, and further, the flow velocity difference is directly utilized to enable the outdoor air at the fresh air outlet 2 to be sucked into a room, and the fresh air function of the fresh air conditioner can be realized without a fresh air fan.
According to the fresh air conditioner provided by the invention, the outlet of the fresh air duct 3 is arranged at the main air outlet 1 of the indoor unit, so that the fresh air duct 3 sucks outdoor air by utilizing the flow velocity difference, the fresh air function of the air conditioner can be realized without arranging a fresh air fan in the fresh air duct 3, the structure is simple, and the electric energy is saved.
Based on the content of the above embodiment, as an alternative embodiment, as shown in fig. 2 and 3, an air conditioner main fan 4, an evaporator 5, a water pan 6 and an exhaust fan 7 are further disposed in the inner space of the indoor unit of the fresh air conditioner; the water receiving disc 6 divides the internal space into an upper space and a lower space which are mutually independent; a first indoor air inlet 8 is provided in the housing of the indoor unit constituting the upper space, and a second indoor air inlet 9 is provided in the housing of the indoor unit constituting the lower space.
The inner space of the indoor unit of the fresh air conditioner provided by the invention is divided into an upper independent space and a lower independent space (respectively called an upper space and a lower space) by the water receiving disc 6.
The water pan 6 may be fixed at a preset position by fastening or by fastening with a screw.
Optionally, the contact part of the water pan 6 and the housing of the indoor unit is sealed in a gluing mode, or is fixedly arranged at a preset position in a gasket laying mode.
Because the main fan 4 and the exhaust fan 7 of the air conditioner are arranged, the functions of the main fan 4 and the exhaust fan 7 are completely different when the fresh air conditioner specifically operates, in order to avoid that the exhaust fan 7 sucks and discharges the circulating air outdoors, thereby influencing the refrigerating or blowing effect of the fresh air conditioner, the two effects of forming the circulating air by the main fan 4 of the air conditioner and forming the negative pressure indoors by the exhaust fan 7 are not interfered by adopting a mode that the upper space and the lower space are independently arranged.
The present invention is not limited to the type and operation parameters of the main fan 4 and the exhaust fan 7.
In addition, the water pan 6 also plays a role in receiving cold and condensed water in the existing air conditioner, and details thereof are omitted.
Based on the above-described embodiments, as an alternative embodiment, the air conditioner main fan 4 and the evaporator 5 are located in the upper space; the main fan 4 drives circulating air to enter from the first indoor air inlet 8, and the circulating air is blown out from the main air outlet 1 of the indoor unit through the evaporator 5; the exhaust fan 7 is positioned in the lower space; the exhaust fan 7 drives the indoor air to enter from the second indoor air inlet 9 and is led out to the outside through an exhaust pipeline so as to form negative pressure in the room.
In the invention, a fresh air conditioner adopts a refrigerating mode as an example, and an air conditioner main fan 4 and an evaporator 5 are arranged in an upper space in an indoor unit, the operation of the air conditioner main fan 4 pumps indoor air into the upper space from a first indoor air inlet 8 to form circulated air, and after the temperature of the air in a high-temperature room is reduced by the evaporator 5, the air is blown out through an indoor unit main air outlet 1.
In this process, the circulating air blown out from the main air outlet 1 of the indoor unit accelerates the flow rate of the outdoor air introduced from the fresh air outlet 2.
In order to further improve the fresh air effect, the invention also adds an exhaust fan 7 in the lower space. During operation, the exhaust fan 7 sucks in indoor air from the room to the lower space through the second indoor air inlet 9 and then exhausts the air to the outside through the exhaust duct.
Since the indoor air is discharged to the outside, a negative pressure environment is formed in the room where the fresh air conditioner is located, and the negative pressure environment further increases the flow rate of the outdoor air introduced from the fresh air outlet 1.
The negative pressure environment is the environment where the indoor air pressure value is larger than the outdoor air pressure value.
Based on the above-described embodiments, as an alternative embodiment, the electric cabinet 10 of the indoor unit is disposed in the lower space; the exhaust fan 7 drives indoor air to enter from the second indoor air inlet 9, pass through the electric cabinet 10 and be led out to the outside through an exhaust pipeline.
The evaporator 5 and the water pan 6 are generally wet in the upper space, so that the invention divides the inner space of the whole indoor unit into the independent upper space and the independent lower space, and the electric cabinet 10 is arranged in the lower space, thereby ensuring the drying of the running environment of the electric cabinet 10, and prolonging the safety life of the electric cabinet 10 on the premise of ensuring the running stability of the electric cabinet 10.
In addition, as shown in fig. 3, in the present invention, by arranging the electric cabinet 10 in the lower space, specifically, arranging the electric cabinet 10 on the air inlet surface of the exhaust fan 7, after the exhaust fan 7 drives the indoor air to enter from the second indoor air inlet 9, the indoor air will pass through the electric cabinet 10 and then be led out of the room. In the process, the exhaust fan 7 can clean the dust of the electric cabinet 10 and remove the condensed water at the bottom of the air conditioner.
Based on the content of the above embodiment, as an alternative embodiment, a swing blade 11 is disposed at the main air outlet 1 of the indoor unit; the fresh air duct 3 related to the fresh air outlet 2 penetrates through the main air outlet 1 of the indoor unit; a window is arranged on a plane formed by the swinging blades 11 when the swinging blades are in a folded state and is used as an outlet of the fresh air duct 3.
The embodiment provides a specific setting mode of the fresh air outlet 2, and is shown in fig. 1 and 2, assuming that the swing blades 11 have 5 rectangular blade components, two ends of the 5 blades are respectively connected to the vertical driving rod.
