Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0027] like Figure 1 and Figure 2 As shown in the illustration, this application provides a fresh air conditioner 1, which includes a casing 10, a fresh air fan 20, and a jet structure 30. This allows for the uniform mixing of outdoor fresh air and indoor return air before air delivery, ensuring that the outdoor fresh air is evenly distributed to the target area, effectively improving indoor air quality. The type of fresh air conditioner 1 can be determined according to actual needs, and can include, for example, wall-mounted air conditioners, cabinet air conditioners, window air conditioners, ceiling-mounted air conditioners, or other types of air conditioners with fresh air functions. This application does not limit this type.
[0028] The housing 10 is equipped with a fresh air duct 11 and an indoor air duct 12, which are connected. A fresh air fan 20 and a jet structure 30 are respectively installed in the fresh air duct 11. The fresh air fan 20 is used to draw outdoor air into the fresh air duct 11, and the jet structure 30 is used to spray the outdoor air introduced by the fresh air fan 20 into the indoor air duct 12.
[0029] When the fresh air function is activated, the fresh air fan 20 draws outdoor air into the fresh air duct 11 through negative pressure. The jet structure 30 sprays the introduced outdoor air to uniformly form multiple high-speed jets of gas. These jets are then sprayed at high speed into the indoor duct 12, facilitating uniform mixing with the indoor return air and improving the mixing uniformity of the outdoor and indoor return air. After the outdoor and indoor return air are uniformly mixed, the mixed gas can be blown to the target area, thereby rapidly improving indoor air quality. Furthermore, by utilizing the jet effect of the jet structure 30 to rapidly introduce outdoor air into the indoor duct 12, the intake velocity and volume of outdoor air can be increased, allowing for the rapid introduction of a larger amount of outdoor air in a short time, thus quickly improving indoor air quality.
[0030] The construction of the jet structure 30 can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, the jet structure 30 may include a jet fan 31 and a jet nozzle 32. The jet fan 31 is used to drive the outdoor air in the fresh air duct 11 to accelerate and flow towards the jet nozzle 32, and the jet nozzle 32 is used to spray the outdoor air into the indoor air duct 12. By setting the jet fan 31 and the jet nozzle 32, the jet fan 31 can be used to increase the flow velocity of the outdoor air before it enters the jet nozzle 32, and then the jet nozzle 32 can be used to spray the accelerated outdoor air to further increase the flow velocity of the jet gas, thereby effectively improving the mixing uniformity of outdoor air and indoor return air, as well as the intake velocity and intake volume of outdoor air.
[0031] In some examples, the jet direction of the jet nozzle 32 is adjustable. This allows the jet nozzle 32 to freely adjust its jet direction according to actual needs, ensuring the jet gas is ejected in the desired direction, further improving flow characteristics and air mixing uniformity. For example, the jet nozzle 32 can be a flexible nozzle with adjustable jet direction, allowing for convenient adjustment of the jet direction.
[0032] In some embodiments, the housing 10 may be provided with a connecting duct 13, which connects the fresh air duct 11 and the indoor air duct 12. The jet structure 30 may be disposed at the connection between the fresh air duct 11 and the connecting duct 13, and the connecting duct 13 gradually narrows along the airflow direction. In other words, the connecting duct 13 is a variable cross-section duct with a gradually decreasing flow cross-section. The connecting duct 13 is used to accelerate the jet gas, further increasing the flow velocity of the jet gas when it enters the indoor air duct 12, thereby improving the mixing uniformity of outdoor air and indoor return air.
[0033] In some embodiments, the fresh air air conditioner 1 may include a first switching valve 40. The first switching valve 40 is disposed between the fresh air duct 11 and the indoor air duct 12, and is used to control the on / off state and air volume between the fresh air duct 11 and the indoor air duct 12. In this way, the opening degree of the first switching valve 40 can be selected and changed according to actual needs to meet the actual air supply requirements.
[0034] In some embodiments, the surface of the housing 10 may be provided with a fresh air outlet 14 and an indoor return air outlet 15, which are arranged adjacent to each other. The fresh air duct 11 may have an air inlet section 111, a first air outlet section 112, and a second air outlet section 113. The fresh air fan 20 is disposed in the air inlet section 111. The first air outlet section 112 is connected to the indoor duct 12, and the second air outlet section 113 is connected to the fresh air outlet 14. A jet structure 30 may be provided at one end of the first air outlet section 112 near the indoor duct 12. In this way, the outdoor air introduced by the fresh air fan 20 can flow to at least one of the first air outlet section 112 and the second air outlet section 113 according to actual needs, and then directly enter the indoor duct 12 through the first air outlet section 112, or enter the room through the second air outlet section 113 and the fresh air outlet 14, and then enter the indoor duct 12 through the indoor return air outlet 15, thereby increasing the diversity of the fresh air function.
[0035] like Figure 3 As shown, in some examples, the fresh air outlet 14 may also be equipped with a jet structure 30. The jet structure 30 provided at the fresh air outlet 14 is used to spray the outdoor air introduced by the fresh air fan 20 into the room. In this way, the introduced outdoor air can be sprayed by the jet structure 30 to uniformly form multiple high-speed jets of gas. These multiple jets of gas are sprayed into the indoor environment at high speed, making it easy to mix evenly with the air in the indoor environment, thereby improving the mixing uniformity of the outdoor and indoor air. After the outdoor and indoor air are uniformly mixed, the mixed gas can flow freely in the indoor environment or enter the indoor air duct 12 from the indoor return air inlet 15 for heat exchange.
[0036] like Figure 1 and Figure 2 As shown, in some examples, the fresh air air conditioner 1 may include the aforementioned first switching valve 40. The first switching valve 40 may be disposed between the first air outlet section 112 and the indoor air duct 12 to control the on / off state and air volume between the first air outlet section 112 and the indoor air duct 12. In this way, the opening degree of the first switching valve 40 can be selected and changed according to actual needs to meet the actual air supply requirements.
[0037] like Figure 3As shown, in some examples, the fresh air air conditioner 1 may include a second switching valve 50. The second switching valve 50 is disposed between the second air outlet section 113 and the fresh air outlet 14, and is used to control the on / off state and airflow between the second air outlet section 113 and the fresh air outlet 14. Thus, whether to open the second switching valve 50 and to change its opening degree can be selected according to actual needs to meet the actual air supply requirements.
[0038] like Figures 1 to 3 As shown, in some embodiments, the indoor air duct 12 may have a main air duct 121 and multiple branch air ducts 122, with the main air duct 121 connected to each of the multiple branch air ducts 122. Multiple indoor air outlets 16 may be provided on the surface of the housing 10, with the number of branch air ducts 122 and indoor air outlets 16 being equal and connected in a one-to-one correspondence. In this way, the airflow in the indoor air duct 12 can be evenly distributed through the multiple branch air ducts 122 and the multiple indoor air outlets 16, resulting in a more uniform and gentle airflow.
[0039] In some embodiments, the fresh air air conditioner 1 may include an indoor heat exchanger and an indoor fan, which are respectively disposed within an indoor air duct 12. The indoor fan is used to draw indoor air into the indoor air duct 12 to form indoor return air, and the indoor heat exchanger is used to regulate the temperature of the indoor return air, such as by heating or cooling.
[0040] The above provides a detailed description of the fresh air conditioner provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
