Referring to fig. 1 and 2, the window type air conditioner of the present invention includes a base plate 10, and an indoor side heat exchange assembly and an outdoor side heat exchange assembly disposed on the base plate 10. The outdoor heat exchange assembly comprises an outdoor heat exchanger 40, an outdoor wind wheel 20 and a back plate 30, and when the window type air conditioner works, the outdoor wind wheel 20 rotates to supply air to the outdoor heat exchanger 40, so that heat exchange is realized.

The upper surface of the chassis 10 is provided with a water collecting tank 11, specifically, the water collecting tank 11 may be formed by locally sinking the upper surface of the chassis 10, or formed by locally flanging the upper surface of the chassis 10, and the water collecting tank 11 is used for collecting condensed water condensed on the surface of the indoor heat exchanger. When the air conditioner indoor unit works, condensed water drops downwards under the action of gravity, is received by the chassis 10 and is collected into the water collecting tank 11 for storage. Outdoor side wind wheel 20 install in chassis 10, and correspond and install in the water catch bowl 11 top, outdoor side wind wheel 20's periphery is equipped with water ring 21, and water ring 21's lower extreme stretches into water catch bowl 11. Thus, when the outdoor wind wheel 20 rotates, the water ring 21 rotates along with the outdoor wind wheel, and the condensed water in the water collecting tank 11 is driven to rise. The rear surrounding plate 30 is disposed on the chassis 10, referring to fig. 1, the rear surrounding plate 30 and the chassis 10 are disposed to surround the periphery of the outdoor side wind wheel 20 together to form an air duct extending in the front-rear direction, in this embodiment, the air duct is in a cylindrical shape extending in the front-rear direction, an air outlet is formed at the rear end of the air duct, an air inlet is formed at the front end of the air duct, and the outdoor side heat exchanger 40 is mounted on the chassis 10 and disposed at the air outlet of the air duct, so that when the outdoor side wind wheel 20 rotates, the driving air flows out from the air outlet from the front-rear direction and blows to the outdoor side heat exchanger 40, thereby achieving heat exchange. Specifically, the outdoor heat exchanger 40 includes fins and refrigerant tubes mounted to the fins. The top plate 31 of the back plate 30 extends backwards to above the heat exchanger, and the rear end of the top plate 31 of the back plate 30 is located right above the refrigerant pipe, so that when the outdoor side wind wheel 20 runs, the water ring 21 throws the water in the water collecting tank 11 to the back plate 30, and the water flows backwards along the back plate 30 and drops to the refrigerant pipe.

In the technical scheme provided by the invention, when the window type air conditioner works, the flow direction of the condensed water flows along the direction of A-B-C-D as shown in figure 4. Specifically, when the outdoor wind wheel 20 operates, the water collecting tray 11 (a) is thrown upward by the water ring 21 to the top plate 31 (B) of the back panel 30 above the water collecting tray 21, and then, water flows backward along the back panel 30 to the top plate 31 (C) above the refrigerant pipe under the action of the wind pressure in the wind channel, and finally drops to the refrigerant pipe (D) below the top plate 31 under the action of gravity. So, on the comdenstion water that is kicked up can directly be drenched the refrigerant pipe from the top, compare on the comdenstion water is drenched the fin, to the technique of refrigerant pipe indirect heat conduction again, the comdenstion water is direct to take away the heat with the contact of refrigerant pipe, and heat exchange efficiency is higher, and is better to the cooling effect of refrigerant pipe.

Those skilled in the art will understand that, the top plate 31 of the back plate 30 is spaced from the coolant pipe in the up-down direction, and specifically, the spacing is not less than 10mm, so that most of the condensate can be directly poured from the coolant pipe without being blocked. However, if the height of the top plate 31 is raised as a whole to ensure the distance between the top plate 31 and the refrigerant pipes, the cross section of the air duct may be too large, and the static pressure in the air duct may not be ensured, and therefore, a first groove 50 extending in the front-rear direction is provided at the lower side of the top plate 31, the opening of the first groove 50 is downward, the front end of the first groove 50 is located above the water beating ring 21, and the rear end of the first groove 50 is located above the refrigerant pipes. So, only set up the first recess 50 that corresponds to refrigerant pipe top in the position that need spray the comdenstion water, on the one hand, only the local height that increases the wind channel cross-section can reduce the wind pressure change that the increase wind channel cross-section brought, and on the other hand, first recess 50 can also play and collect the effect with the guide to the comdenstion water for the comdenstion water can spray to refrigerant pipe more smoothly on. Preferably, the first groove 50 is disposed at a position corresponding to the refrigerant pipe, so that more condensed water is guided to the refrigerant pipe where heat dissipation is most needed, and heat exchange efficiency is further improved.

On the basis of the above embodiment, referring to fig. 2, fig. 3 and fig. 8, a water baffle 51 is disposed at the rear end of the first groove 50, and the water baffle 51 extends downward from the bottom of the first groove 50 to cover the opening of the first groove 50 toward the rear side. Therefore, the water baffle 51 can guide the condensed water flowing along the front-back direction, and the condensed water is guided to the refrigerant pipe below the water baffle 51, so that more condensed water is directly contacted with the refrigerant pipe for heat exchange, and the heat exchange efficiency is further improved.

Specifically, referring to fig. 8 and 11 to 14, the splash plate 51 is connected to the top plate 31 in a vertically-rotatable manner, so as to have a connecting side 511 connected to the rear end of the top plate 31 and a rotating side 512 rotating around the connecting side 511. Thus, referring to fig. 12, when the rotating side 512 rotates upward around the connecting side 511 to a position where the splash plate 51 is coplanar with the top plate 31, the splash plate 51 is in an open state, and as shown in fig. 13, when the rotating side 512 rotates downward to a position perpendicular to the top plate 31, the splash plate 51 is in a closed state. Thus, on the one hand, when the back panel 30 is assembled, the back panel 30 can be mounted in place, and then the water guard plate 51 is closed to facilitate mounting. On the other hand, in the assembling and maintaining process of the window type air conditioner, when the water baffle 51 is in the open state, the constructor can conveniently observe whether the position of the back panel 30 corresponds to the position of the outdoor side wind wheel 20 covered by the back panel 30 or not from the opening of the first groove 50 towards the rear side, so that the relative position of the top plate 31 of the back panel 30 between the outdoor side wind wheels 20 is ensured, and the condensate water can be ensured to flow backwards to the refrigerant pipe along the first groove 50.

The splash plate 51 may be pivotally mounted to the top plate 31 in a variety of ways, such as by a hinge. In the present embodiment, further, for the convenience of production, referring to fig. 12 and 13, the water guard plate 51 is integrally provided with the top plate 31, and the connecting side 511 of the water guard plate 51 has a folding groove 513 extending in the transverse direction, and the plate thickness at the folding groove 513 is smaller than the plate thickness at both sides of the folding groove 513, so that the water guard plate 51 is foldably and rotatably connected to the top plate 31. Thus, the top plate 31 and the splash guard 51 can be produced more simply, the assembly is facilitated, and on the other hand, the sealing performance between the splash guard 51 and the top plate 31 can be ensured by dripping better, so that the condensed water is prevented from leaking out from the gap between the splash guard 51 and the top plate 31.

In one embodiment, the water guard plate 51 is provided with a buckle 514, the top plate 31 is provided with a slot 515 corresponding to the buckle 514, and the buckle 514 has a guiding inclined plane 5140 corresponding to the slot 515, so as to guide the buckle 514 to smoothly slide into the slot 515 for fixing and be clamped in the slot 515. So when the back panel 30 is assembled, press down breakwater 51, can fix the baffle in the closed position very conveniently, and when needing to overhaul, press buckle 514, just can make buckle 514 deviate from draw-in groove 515 to conveniently open breakwater 51 once more.

If the height undersize of recess, most comdenstion water will be sheltered from, can't backward flow to heat exchanger, and if the recess height is too big, the recess will can't play the drainage effect to can lead to static pressure in the wind channel to reduce, can't provide sufficient wind pressure and make the comdenstion water flow backward. For this reason, referring to fig. 3, in order to ensure that the first groove 50 provides a sufficient height, the vertical distance H between the bottom surface 52 of the first groove 50 and the outer edge of the water ring 21 is not less than 10mm, and not more than 50 mm. Therefore, the optimal condensate water drainage effect can be obtained on the premise of ensuring the air pressure. So that as much condensed water as possible is guided to the upper part of the refrigerant pipe of the outdoor side heat exchanger 40, and the heat exchange efficiency is improved.

Further, if the width of the groove is too narrow, most of the condensed water will be blocked and cannot flow backwards to the heat exchanger, and if the width of the groove is too large, the static pressure in the air duct may be reduced, and sufficient air pressure cannot be provided to promote the condensed water to flow backwards. For this reason, in the present embodiment, referring to fig. 9 and 10, both sides of the chassis 10 respectively have a first edge 12 and a second edge 13 extending in the front-back direction, and a span L of the first groove 50 in a direction from the first edge 12 to the second edge 13 is not less than 60mm and not more than 250 mm. So, can compromise the wind pressure size in the wind channel and ensure that the comdenstion water sprays to outdoor side heat exchanger 40 more evenly, promote the cooling effect of comdenstion water to outdoor side heat exchanger 40.

In one embodiment, the cross section of the first groove 50 is gradually enlarged from top to bottom. Therefore, inclined planes which are inclined upwards and inwards are formed on two sides of the groove, so that condensed water in the air duct can be collected better.

In an embodiment, referring to fig. 8 to 10, a second groove 60 is further disposed on a lower side of the top plate 31, the second groove 60 is disposed on at least one side of the first groove 50, an opening of the second groove 60 is downward, and a rear end of the second groove 60 is located above the refrigerant pipe. So, can correspond the refrigerant pipe and set up first recess 50 and second recess 60 for the comdenstion water that is upwards thrown away by water ring 21 collects and the water conservancy diversion to the direction of predesign under the guide effect of first recess 50 and second recess 60, and the refrigerant pipe department that the flow direction heat transfer demand is great promotes heat transfer effect.

On the basis of the previous embodiment, referring to fig. 1 and 7, the window type air conditioner further includes a housing, and the housing covers the indoor side heat exchange assembly and the outdoor side heat exchange assembly of the air conditioner, so as to protect the internal components of the air conditioner. The upper wall of the housing is arranged on the upper side of the top plate 31, sponge rubber is adhered to the lower side of the upper wall, and the sponge rubber covers the opening of the second groove 60 towards the rear side. In the implementation, the sponge rubber is a porous material formed by foaming rubber, has good shock absorption performance and has certain sealing performance. So, sponge rubber covers the opening of second recess 60 towards the rear side on the one hand, makes the comdenstion water in the second recess 60 flow to the refrigerant pipe downwards, plays to comdenstion water direction and sealed effect, and on the other hand rubber sponge is in between outdoor side heat exchanger 40 and the roof 31, when the roof 31 pressurized, can play certain cushioning effect to the protection heat exchanger.

The wind collecting ring 33 increases the wind pressure at the wind inlet of the wind channel, so that the airflow flows backwards more smoothly.

In this embodiment, the connection between the wind-collecting ring 33 and the front plate 32 is arc-shaped. Thereby reducing the resistance to the airflow and enabling the airflow to flow into the air duct more smoothly.

Further, referring to fig. 3 and 5, the top end of the wind collecting ring 33 is disposed below the top plate 31, so as to form a water chute 330 with a backward opening between the top plate 31 and the wind collecting ring 33. In this embodiment, most of the condensed water raised by the water ring 21 flows backward under the action of wind pressure and is sprayed to the outdoor side for heat exchange, and a small part of the condensed water flows forward, as shown in fig. 5 and 6, the flow direction of the part of the condensed water flows along the path of a-B-E-F, the condensed water is thrown from the water collecting tank 11 (a) to the lower side (B) of the top plate 31 above the water ring 21 under the action of the water ring 21, and the part of the condensed water flows forward under the action of centrifugal force and is received at the water guiding tank 330 (E), and then the condensed water is guided along the arc-shaped channel (F) formed outside the wind collecting ring 33, falls under the action of gravity, and returns to the water collecting tank 11 below. In this embodiment, the water collecting ring and the back panel 30 form an enclosed space to guide the scattered condensed water to flow back to the water collecting tank 11, so that the condensed water can be recovered, and the condensed water can be prevented from splashing to electronic devices such as a wind wheel motor or a compressor, thereby protecting the electronic devices inside the window type air conditioner. Preferably, referring to fig. 4, 5 and 7, the bottom surface 52 of the first groove 50 is inclined downward from the upper side of the water ring 21.
