In the embodiment of the present invention, as shown in fig. 1 to 7, the window type air conditioner includes a base plate 100, an indoor duct case 200, an indoor side heat exchanger 300, and a fresh air device 400. An indoor duct case 200 is installed at a front side of the base pan 100, and an indoor air duct 210 is formed in the indoor duct case 200. The indoor heat exchanger 300 is installed on the base plate 100 and is disposed corresponding to an air inlet end of the indoor air duct 210. The fresh air device 400 is installed on the base plate 100 and is used for conveying fresh air indoors. The fresh air device 400 comprises a fresh air shell 410 extending from the outdoor to the indoor side, the fresh air shell 410 is provided with a fresh air inlet 411 communicated with the outdoor, a fresh air outlet 412 communicated with the indoor and a fresh air duct 413 communicated with the fresh air inlet 411 and the fresh air outlet 412, and the fresh air outlet 412 is arranged adjacent to the windward side of the indoor side heat exchanger 300.
In this embodiment, the base pan 100 provides mounting and support for the internal structure of a window air conditioner. The air conditioner indoor unit further includes a case 500, and the case 500 is mounted to the base pan 100 such that the case 500 and the base pan 100 form an outer frame of the entire window type air conditioner indoor unit, and the window type air conditioners are mounted in a receiving space formed by the case 500 and the base pan 100. The shape of the housing 500 may be square, cylindrical, etc., and may be selected according to specific use requirements, and is not particularly limited herein. Typically, the housing 500 is generally square in shape for ease of manufacture and molding. An outdoor air duct shell positioned at the rear side of the chassis 100 is further arranged in the shell 500, an outdoor air duct is formed in the outdoor air duct shell, and an outdoor fan and an outdoor heat exchanger 700 are arranged in the outdoor air duct and used for driving outdoor airflow to enter the outdoor air duct to dissipate heat of the outdoor heat exchanger 700. The rear side wall of the casing 500 is provided with an outdoor air inlet and a fresh air inlet, and the fresh air inlet is communicated with the fresh air inlet 411. The extension direction of the indoor duct case 200 generally coincides with the length direction of the base pan 100. The indoor heat exchanger 300 may be installed in the indoor air duct casing 200, or may be installed at a position outside the indoor air duct casing 200 corresponding to the air inlet end of the indoor air duct 210, so that only the airflow blown out from the indoor air duct 210 is the airflow after heat exchange by the indoor heat exchanger 300.
The casing 500 is provided with an indoor air inlet 510 and an indoor air outlet, an air inlet end of the indoor air duct 210 is communicated with the indoor air inlet 510, and an air outlet end of the indoor air duct 210 is communicated with the indoor air outlet. Both the indoor air inlet 510 and the indoor air outlet may be formed on the front sidewall of the housing 500. Or the indoor intake vent 510 is located at the front side wall surface of the housing 500 and the indoor exhaust vent is located at the top surface of the housing 500. The indoor air outlet can also be located at the junction of the front side wall surface and the top surface of the casing 500. An indoor fan, which may be a centrifugal fan or a cross-flow fan, may also be disposed in the indoor air duct 210. Fresh air and indoor airflow are introduced from the indoor air inlet 510 by the indoor fan, and then flow through the indoor air duct 210 after heat exchange by the indoor heat exchanger 300, and are blown out from the indoor air outlet.
The fresh air inlet 411 and the fresh air outlet 412 may be rectangular, circular, elongated, oval, or may be a plurality of micro-holes, which is not limited herein. A fresh air fan may be provided in the fresh air duct 413 for directing the air flow from the fresh air inlet 411 to the fresh air outlet 412. In other embodiments, the fresh air inlet 411 may be connected to the outdoor air duct, so that an outdoor fan may be used to blow the outdoor air flow into the fresh air duct 413 and out of the fresh air outlet 412. Whether the window type air conditioner needs to start the dehumidification mode or not is judged, and the dehumidification mode can be judged through an indoor temperature sensing device and a humidity sensing device.
It can be understood that the fresh air case 410 extends from the outdoor to the indoor side, that is, the fresh air case 410 extends from the outdoor air duct case side to the indoor air duct case 200 side. Thus, the fresh air inlet 411 of the fresh air shell 410 on one side of the outdoor air duct shell is communicated with the outdoor, the fresh air outlet 412 of the fresh air shell 200 on one side of the indoor air duct shell is communicated with the indoor, and outdoor air flow is directly introduced into the indoor through the independent fresh air duct 413. The fresh air outlet 412 is communicated with the indoor space, which means that the airflow blown out from the fresh air outlet 412 is directly blown into the indoor space, but not blown into the indoor air duct 210, and is indirectly blown into the indoor space through the indoor air duct 210. Since the indoor duct case 200 requires a sufficient space, the indoor duct case 200 and the indoor side structure are generally adapted to the length of the base chassis 100, so that the overall structure is more compact. The fresh air shell 410 is installed on the base plate 100 and extends from the outdoor to the indoor side, and then the fresh air shell 410 can directly penetrate through the indoor air duct shell 200, and the sealing structure is arranged at the joint of the fresh air shell 410 and the indoor air duct shell 200 to realize sealing. In another embodiment, a portion of the fresh air case 410 is located between the lower end of the indoor duct case 200 and the base pan 100. So that a part of the fresh air case 410 is positioned below the indoor air duct case 200, that is, so that the fresh air case 410 is introduced into the room from below the indoor air duct case 200. Thus, the fresh air case 410 does not interfere with the indoor air duct 210, and it is not necessary to perforate the indoor air duct case 200 and provide a sealing structure, etc., thereby simplifying the manufacturing process and the installation difficulty. Meanwhile, the occupied space of the fresh air shell 410 is reduced, so that the structure of the whole machine is more compact, and the requirement of independent air outlet of fresh air is met without additionally increasing the volume of the whole machine.
It should be noted that the fresh air outlet 412 is disposed adjacent to the windward side of the indoor side heat exchanger 310, and the distance between the fresh air outlet 412 and the windward side of the indoor side heat exchanger 310 is less than or equal to 10% of the thickness of the indoor side heat exchanger 310. The fresh air outlet 412 may be flush with the windward side of the indoor side heat exchanger 310 or the fresh air outlet 412 may be disposed to protrude from the windward side of the indoor side heat exchanger 310. That is, the end of the fresh air case 410 is made flush with the windward surface of the indoor-side heat exchanger 310 or is disposed protruding from the windward surface of the indoor-side heat exchanger 310. So, new trend wind channel 413 can directly extend to indoor heat exchanger's windward side, is favorable to the new trend to carry out the dehumidification through indoor side heat exchanger 310 more. The end of the fresh air case 410 may not extend out of the windward side of the indoor heat exchanger 310, and the fresh air outlet 412 may be adjacent to the windward side of the indoor heat exchanger 310. At this time, the fresh air blown out from the fresh air outlet 412 can be blown into the room through a passage surrounded by the bottom wall of the indoor heat exchanger 310, the chassis 100, and the casing 500.
By arranging the fresh air outlet 412 adjacent to the windward side of the indoor heat exchanger 300, fresh air enters the fresh air duct 413 from the fresh air inlet 411 and is blown out from the fresh air outlet 412, the indoor fan sucks the air flow blown out from the fresh air outlet 412 and the indoor air flow into the indoor air duct 210 after the indoor heat exchanger 300 is dehumidified, and the dehumidified mixed air flow is blown out from the indoor air outlet by the indoor fan. So, can utilize indoor side heat exchanger 300 to dehumidify, need not set up in addition the new trend evaporimeter, then greatly reduced manufacturing cost, improved the efficiency. And because most of the air current that the new trend export 412 blew out can pass through indoor side heat exchanger 300 earlier and dehumidify before fully mixing with indoor air current, then can avoid not passing through the new trend of dehumidification and entering indoor, influence indoor humidity and temperature after mixing with indoor air current to user's comfort level in utilization improves greatly.
The window type air conditioner of the present invention is constructed such that the fresh air case 410 extends from the outdoor side to the indoor side, and the fresh air outlet 412 of the fresh air case 410 is adjacent to the windward side of the indoor side heat exchanger 300. Make the air current that blows off from new trend export 412 can flow through indoor side heat exchanger 300 immediately and inhale indoor side wind channel 210 in, blow off by indoor air outlet again, thereby most fresh air that does not dehumidify before with indoor air current intensive mixing, can dehumidify through indoor side heat exchanger 300 earlier, then blow in indoorly, the circulation route of fresh air has been reduced greatly, reduce the mixing rate of fresh air that does not pass through the dehumidification and indoor wind, make the influence of fresh air to indoor temperature and humidity littleer, thereby user's comfort in use is better.
In the above embodiment where the coupling portion of the fresh air case 410 is located between the lower end of the indoor air duct case 200 and the base plate 100, further, the fresh air case 410 located below the indoor air duct case 200 is spaced apart from the lower end of the indoor air duct case 200. It should be noted that the gap between the lower end of the indoor air duct shell 200 and the fresh air duct shell 410 should be minimized under the condition that the gravity of the indoor air duct shell 200 is not transmitted to the fresh air duct shell 410, so that the air leakage phenomenon can be avoided. Typically, the gap between the fresh air casing 410 and the lower end of the indoor air duct casing 200 is made to be less than or equal to 5 mm. Through making the new trend shell 410 and the lower extreme of indoor wind channel shell 200 be the clearance setting, then new trend shell 410 can not the bearing, and then makes new trend shell 410 not fragile.
