Fig. 1 to 13 are drawings showing an embodiment of a window type air conditioner according to the present invention. In the embodiment of the window type air conditioner provided by the invention, the window type air conditioner is formed by integrally manufacturing an indoor unit and an outdoor unit, and the whole window type air conditioner is arranged on a window frame of a building, so that the indoor environment can be cooled or heated. The window type air conditioner can also introduce outdoor fresh air into the room, and the wind speed of the introduced fresh air is high, and the fresh air volume is large. Hereinafter, an embodiment of the window type air conditioner will be described.
Referring to fig. 1 to 3, in an embodiment of the window type air conditioner 100 of the present invention, the window type air conditioner 100 includes a cabinet 110 and a fresh air case 200, the cabinet 110 includes an indoor portion 101 and an outdoor portion 102, and the fresh air case 200 is installed in the cabinet 110. The fresh air shell 200 is configured with a fresh air inlet 201 positioned in the outdoor part 102 and a fresh air outlet 202 positioned in the indoor part 101, and a fresh air duct communicating the fresh air inlet 201 and the fresh air outlet 202 is formed inside the fresh air shell 200 and is suitable for sending air of an outdoor environment into the indoor environment. The fresh air duct includes an air inlet section 230 corresponding to the fresh air inlet 201 and an air outlet section 240 corresponding to the fresh air outlet 202, and the ventilation cross-sectional area of the air outlet section 240 is smaller than that of the air inlet section 230.
Specifically, the housing 110 has a front surface, a back surface, side surfaces, and a top surface. The top surface can be a plane with a horizontal design, or can be composed of a plane and an inclined plane connected with the front end of the plane. Here, an indoor intake port 103 is provided on the front surface of the casing 110, and an indoor exhaust port 104 is provided on the front end (i.e., the inclined surface) of the top surface of the casing 110. The back of the casing 110 is provided with an outdoor air inlet, and the side of the casing 110 is provided with an outdoor air outlet.
The window air conditioner 100 further includes an indoor duct housing 160 and an outdoor duct housing 170. The indoor air duct casing 160 is mounted to the indoor portion 101 of the casing 110 to form an indoor air duct for communicating the indoor air inlet 103 and the indoor air outlet 104. The outdoor air duct case 170 is installed at the outdoor portion 102 of the cabinet 110 to form an outdoor air duct communicating the outdoor air inlet and the outdoor air outlet. The window air conditioner 100 also includes an indoor heat exchanger 120 and an outdoor heat exchanger 130. Wherein, the indoor heat exchanger 120 is installed at the indoor portion 101 of the casing 110 and corresponds to the indoor air inlet 103; the outdoor heat exchanger 130 is installed at the outdoor portion 102 of the cabinet 110 and corresponds to the outdoor intake vent. The window type air conditioner 100 further includes an indoor fan 140 and an outdoor fan 150. The indoor fan 140 is installed in the indoor air duct, and is configured to drive air to enter the indoor air duct from the indoor air inlet, and then to be blown out from the indoor air outlet after exchanging heat with the indoor heat exchanger 120. The outdoor fan 150 is installed in the outdoor air duct to drive air to enter the outdoor air duct from outdoor air, and then to exchange heat with the outdoor heat exchanger 130 and blow out from an outdoor air outlet.
As for the fresh air case 200, the fresh air case 200 may be installed at the left or right side of the cabinet 110, and the fresh air case 200 extends from the outdoor portion 102 of the cabinet 110 to the indoor portion 101 thereof. When the window air conditioner 100 is in the fresh air mode, fresh air in the outdoor environment enters from the fresh air inlet 201 of the fresh air casing 200, flows to the fresh air outlet 202 through the air inlet section 230 and the air outlet section 240 of the fresh air duct in sequence, and is blown out from the fresh air outlet 202. By reasonably designing the position of the fresh air outlet 202 of the fresh air shell 200, the air blown out from the fresh air outlet 202 can be directly blown out from the indoor air inlet 103 of the machine shell 110 to an indoor room; alternatively, the air blown out from the fresh air outlet 202 may be blown to the air intake side of the indoor heat exchanger 120, and then, after heat exchange or dehumidification by the indoor heat exchanger 120, may be blown out from the indoor air outlet 104 to the indoor environment.
According to the technical scheme, the area of the ventilation cross section of the air outlet section 240 of the fresh air duct is smaller than that of the air inlet section 230, so that the air flow is extruded and compressed into the air outlet section 240 in the process of entering the air outlet section 240 from the air inlet section 230, the air pressure of the fresh air in the air outlet section 240 is increased due to extrusion of the fresh air, the fresh air with higher air pressure rapidly flows to the fresh air outlet 202, the fresh air obtains higher air speed, and then the fresh air is rapidly blown out from the fresh air outlet 202, and the fresh air volume is effectively increased. The shape and structure of the fresh air duct 200 are not limited, and the ventilation cross-sectional area of the air outlet section 240 of the fresh air duct is required to be smaller than that of the air inlet section 230. As will be described in more detail below.
Referring to fig. 1, fig. 2 and fig. 8, in an embodiment, the fresh air blown out from the fresh air casing 200 may be directly blown out from the indoor air duct through the indoor air outlet 104, or may be blown out directly from the air inlet side of the indoor heat exchanger 120, so as to be blown out from the indoor air duct through the indoor air outlet 104 after being subjected to heat exchange by the indoor heat exchanger 120, or may be blown out directly from the indoor air inlet 103. In this embodiment, the window air conditioner 100 further includes an indoor heat exchanger 120 mounted to the indoor portion 101; the air outlet section 240 includes a first air outlet portion 241 connected to the air inlet section 230 and extending in a horizontal direction, and a second air outlet portion 242 connected to the first air outlet portion 241 and extending in a longitudinal direction. The first air outlet portion 241 is located below the indoor heat exchanger 120, and the second air outlet portion 242 is located on the air inlet side of the indoor heat exchanger 120.
Specifically, the first air outlet portion 241 and the second air outlet portion 242 of the air outlet section 240 are substantially L-shaped, and the fresh air outlet 202 of the fresh air casing 200 corresponds to the second air outlet portion 242. Because the portion of the fresh air casing 200 corresponding to the second air outlet portion 242 is located on the air inlet side of the indoor heat exchanger 120, the fresh air blown out from the fresh air outlet 202 of the fresh air casing 200 can be directly blown out from the front side of the window air conditioner 100, or can pass through the indoor heat exchanger 120 via the air inlet side of the indoor heat exchanger 120 and enter the indoor air duct, and then be blown out from the indoor air outlet 104.
In addition, because the ventilation cross section area of the air outlet section 240 is smaller, the partial volume of the fresh air shell 200 corresponding to the air outlet section 240 can be correspondingly designed to be smaller, and then the fresh air shell can be easily installed below the indoor heat exchanger 120, the occupied space is smaller, and the position for installing the fresh air shell 200 does not need to be reserved between the indoor fan 140 and the indoor heat exchanger 120.
Further, the cabinet 110 is configured with an indoor intake opening 103 at a front surface of the indoor portion 101, and an outdoor outtake opening at a top surface corresponding to the indoor portion 101; the fresh air outlet 202 of the fresh air casing 200 is formed on the sidewall of the second air outlet portion 242, and the fresh air outlet 202 is suitable for blowing air to the air inlet side of the indoor heat exchanger 120 or blowing air to the indoor air inlet 103.
In an embodiment, to facilitate the installation of the fresh air casing 200, a portion of the fresh air casing 200 corresponding to the first air outlet portion 241 is disposed in a flat shape, so that the thickness of the portion of the fresh air casing 200 corresponding to the first air outlet portion 241 is smaller, and thus the portion of the fresh air casing 200 corresponding to the first air outlet portion 241 can be embedded between the chassis 111 of the casing 110 and the bottom of the indoor heat exchanger 120. In addition, the design can make the first air outlet portion 241 narrower than the air inlet section 230, which is helpful to increase the air pressure of the first air outlet portion 241, and further can drive the air flow to blow out at high speed.
Referring to fig. 1, fig. 2 and fig. 8, based on any of the above embodiments, the shape of the air intake section 230 of the fresh air duct in the fresh air casing 200 may be a straight cylinder with a constant ventilation cross section, or may be an irregular shape with a gradually changing ventilation cross section. It is considered that, if the air inlet section 230 is designed in a straight cylinder shape, and the first air outlet portion 241 of the air outlet section 240 connected to the air inlet section 230 is designed in a flat shape, a sudden change of the cross-sectional area (similar to the cross-sectional area decreasing from the air inlet section 230 to the air outlet section 240) occurs between the air inlet section 230 and the air outlet section 240, and a large wind resistance is formed at the position of the sudden change of the cross-sectional area, which is not favorable for the airflow.
In view of this, the air intake section 230 may be an irregular design with gradually changing ventilation cross section. Optionally, the air inlet section 230 includes an air inlet portion 231 disposed in a cylindrical shape, and an air guiding portion 232 connecting the air inlet portion 231 and the air outlet section 240, and a ventilation cross section of the air guiding portion 232 is disposed in a tapered shape from the air inlet portion 231 to the air outlet section 240.
Specifically, the air passes through the air inlet 231 and enters the air guiding portion 232, and then is guided by the air guiding portion 232 to enter the air outlet section 240, and finally is blown out from the fresh air outlet 202 of the air outlet section 240. Because the cross sectional area of the ventilation of the air guiding portion 232 is gradually reduced from the air inlet portion 231 to the air outlet section 240, the cross sectional area between the air inlet section 230 and the first air outlet portion 241 of the air outlet section 240 can be prevented from suddenly changing, and then a large air resistance can be prevented from being formed at the position, so that the air flow can smoothly enter the air outlet section 240 from the air inlet section 230.
Further, the fresh air case 200 includes a bottom case 210 and a case cover 220 covering the bottom case 210, a top wall of the case cover 220 is configured with an air guiding wall 221 at a portion corresponding to the air guiding portion 232, and the air guiding wall 221 is arranged in an arc shape from top to bottom so as to gradually taper the air guiding portion 232. In addition, the air guiding wall 221 is designed in an arc shape, so that the air guiding wall 221 has better strength and is not easy to deform.
Referring to fig. 8 to 10, in order to enhance the strength of the air guiding wall 221, a convex hull 222 may be convexly formed on a portion of the housing cover 220 corresponding to the air outlet section 240, the convex hull 222 is close to the air guiding wall 221, and a mounting groove 223 for mounting the indoor heat exchanger 120 of the window air conditioner 100 is formed on a side of the housing cover 220 away from the air guiding portion 232 of the convex hull 222.
Specifically, the convex hull 222 is close to the air guiding wall 221, so that the convex hull 222 can serve as a reinforcing structure of the air guiding wall 221 to strongly support the air guiding wall 221, so that the air guiding wall 221 is not easily deformed. The convex hull 222 is formed by locally raising the shell cover 220 of the fresh air shell 200, so that an expansion groove is formed on the shell cover 220 at the inner side of the convex hull 222, and the expansion groove is in butt joint with the air guide part 232, so that the expansion groove forms a part of a fresh air duct. The expansion groove can compensate the air duct space occupied by the first concave portion of the bottom case 210, so that the areas of the front and rear ventilation cross sections of the air outlet section 240 are substantially the same. Moreover, the capacity expansion groove is located at the turning position between the air inlet section 230 and the air outlet section 240, so that the air duct space at the turning position between the air inlet section 230 and the air outlet section 240 can be increased, which is helpful for reducing the resistance of the turning position to the airflow flow, so that the airflow can smoothly enter the air outlet section 240 from the air inlet section 230, and the air volume is increased; and moreover, the air flow can be prevented from colliding with the inner wall of the air duct at the turning part, and further, the generation of large noise is avoided.
In one embodiment, the window type air conditioner 100 further includes a fresh air blower 300, and the fresh air blower 300 may be installed outside the fresh air casing 200 or inside the fresh air casing 200. Specifically, the fresh air blower 300 is installed inside the fresh air casing 200 and located at the air inlet portion 231 of the air inlet section 230 of the fresh air casing 200, so that the fresh air blower 300 forms a larger air pressure at the air inlet section 230 of the fresh air casing 200, and thus more fresh air is driven to enter the fresh air casing 200, and the fresh air volume is increased.
Referring to fig. 5 to 7, according to any of the above embodiments, since the fresh air case 200 is mounted on the chassis 111, the upper surface of the chassis 111 is generally irregular, and the chassis 111 has an uneven surface, the bottom case 210 of the fresh air case 200 and the chassis 111 may be approximately matched in shape to ensure the stable mounting of the fresh air case 200, and may be designed accordingly according to the uneven position of the chassis 111.
Referring to fig. 8 to 10, in an embodiment, the bottom plate 111 is formed with a water receiving slot 11 corresponding to the indoor portion 101 of the casing 110, the bottom shell 210 of the fresh air casing 200 is formed with a protrusion 211 at a position corresponding to the water receiving slot 11, and the protrusion 211 is correspondingly matched with the water receiving slot 11. Wherein, the water receiving tank 11 is installed corresponding to the indoor air duct shell 160 and the indoor heat exchanger 120. The drain pan 210 of new trend shell 200 corresponds the one end cooperation with this water receiving tank 11 through bellying 211, and this bellying 211 forms with the bottom surface of water receiving tank 11 has the face contact, has increased the cooperation area of drain pan 210 and water receiving tank 11 of new trend shell 200 to make new trend shell 200 be difficult for taking place to rock in this water receiving tank 11 department, the stability of reinforcing new trend shell 200 installation.
Further, the chassis 111 is configured to form a sink 14 corresponding to the outdoor portion 102 of the cabinet 110, the chassis 111 forms a first boss 12 between the sink 14 and the water receiving tank 11, and the bottom case 210 of the fresh air case 200 is correspondingly engaged with the first boss 12. The water receiving tank 11 and the sinking tank 14 are separated by the first boss 12, so that water in the sinking tank 14 is not easy to overflow back to the water receiving tank 11, and overflow to indoor rooms is avoided.
It is considered that if the portion of the fresh air casing 200 corresponding to the air intake section 230 is correspondingly matched with the sink 14, water in the sink 14 may enter the fresh air duct from the fresh air inlet 201 of the fresh air casing 200, which may cause the fresh air to be too humid or to blow water.
Referring to fig. 8 to 11, in order to avoid the above situation, a second protrusion 13 may be further formed between the chassis 111 and the first protrusion 12 on one side of the sinking groove 14, the second protrusion 13 is higher than the first protrusion 12, a second recess 213 is formed in the bottom shell 210 of the fresh air shell 200 at a position corresponding to the sinking groove 14, and the second recess 213 is supported by the second protrusion 13 to space the bottom shell 210 of the fresh air shell 200 from the bottom of the sinking groove 14.
Specifically speaking, the second concave part 213 of the fresh air shell 200 is supported by the second boss 13, which is equivalent to lifting the fresh air inlet 201 of the fresh air shell 200 by the second boss 13, so that the water in the sink tank 14 is not easy to enter the fresh air duct from the fresh air inlet 201 of the fresh air shell 200, and further the phenomenon that the fresh air is too humid or blows water is avoided.
In summary, the water receiving tank 11 of the chassis 111 is combined with the first boss 12 and the second boss 13 to be substantially arranged in a step shape; accordingly, the combination of the protrusion 211 and the first and second recesses 212 and 213 on the bottom shell 210 of the fresh air case 200 is also substantially designed in a step shape, so that the fresh air case 200 can be substantially adapted to the shape of the bottom plate 111.
Further, considering that the fresh air inlet 201 of the fresh air casing 200 needs to be close to the outdoor air inlet, an end of the fresh air casing 200 close to the fresh air inlet 201 extends from above the sink 14 to the outdoor air inlet, that is, the second concave portion 213 of the fresh air casing 200 is suspended above the sink 14, so that the fresh air casing 200 may topple over the sink 14. In order to avoid this, a support frame 214 may be protruded from a lower surface of the second concave portion 213, and the support frame 214 is adapted to be supported by a groove bottom divider of the sink 14 to support the fresh air case 200, so that the fresh air case 200 is not prone to toppling over to the sink 14, and the installation stability of the fresh air case 200 is greatly improved.
Referring to fig. 6 to 8, based on any of the above embodiments, the window air conditioner 100 further includes a water pan 400 installed in the water receiving tank 11, and the water pan 400 is adapted to receive condensed water generated by the indoor heat exchanger 120.

Because one end of the water collector 400 extends to the upper side of the fresh air shell 200, if one end of the water collector 400 far away from the fresh air shell 200 is suspended, the water collector 400 can shake unstably. In order to solve the problem, the window type air conditioner 100 further includes a pad disposed in the water receiving slot 11, and the pad is located at one side of the fresh air case 200 and is flush with the portion of the fresh air case 200 located in the water receiving slot 11, so as to support the water receiving tray 400 in cooperation with the portion of the fresh air case 200 located in the water receiving slot 11. The backing plate can be made of elastic or flexible materials such as foam or sponge, and therefore the backing plate can be contacted with the bottom surface of the water pan 400 more tightly and has higher stability.
Further, in order to discharge the water of the drain pan 400, a drain groove 410 is formed at the drain pan 400, and the drain groove 410 extends from the drain pan 400 toward the sink groove 14 for discharging toward the sink groove 14 of the bottom plate 111. And finally discharged to the outdoor environment through sink 14.
