[0028] Hereinafter, a window type air conditioner 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0029] like Figure 1-Figure 5 As shown, according to the window air conditioner 100 of the embodiment of the utility model, it includes an outdoor unit part 2 suitable for being arranged outdoors and an indoor unit part 1 suitable for being arranged indoors, the indoor unit part 1 and the outdoor unit part 2 are spaced apart in the front-to-back direction, and are connected by a connecting part 3 located at the upper part between the indoor unit part 1 and the outdoor unit part 2; wherein, the bottom plate 31 of the connecting part 3 includes a sinking groove part 311 and a step part 312 connected and arranged in the front-to-back direction, the step part 312 is higher than the groove bottom wall 3111 of the sinking groove part 311 and is supported on the top end of the back plate 21 of the outdoor unit part 2, the sinking groove part 311 is located on the side of the outdoor unit part 2 close to the indoor unit part 1, the groove bottom wall 3111 of the sinking groove part 311 is lower than the top end of the back plate 21 of the outdoor unit part 2 and is arranged adjacent to the back plate 21 of the outdoor unit part 2, and a drainage hole 313 is penetrated on the bottom wall of the sinking groove part 311.

[0030] As a result, the liquid flowing into the connection between the connecting part 3 and the external unit part 2 can flow to the bottom wall 3111 of the groove part 311, and be discharged to the bottom of the connecting part 3 through the drainage hole 313, thereby preventing the liquid from flowing into the connecting part 3 or the external unit part 2 and causing a short circuit, thereby improving the reliability of the window air conditioner 100.

[0031] First, if Figure 1 As shown, the window type air conditioner 100 comprises an inner unit part 1, an outer unit part 2 and a connecting part 3. The inner unit part 1 and the outer unit part 2 are connected along Figure 1 As shown, the front-to-back directions are arranged at intervals, for example, the indoor unit part 1 is arranged in front of the outdoor unit part 2, the indoor unit part 1 is arranged indoors, and the outdoor unit part 2 is arranged outdoors.

[0032] The connecting portion 3 is extended in the front-to-back direction and is located at the upper part between the indoor unit portion 1 and the outdoor unit portion 2. The two ends of the connecting portion 3 are respectively connected to the upper end of the indoor unit portion 1 and the upper end of the outdoor unit portion 2, so that the window air conditioner 100 is generally saddle-shaped, so as to form an avoidance groove 5 between the indoor unit portion 1, the connecting portion 3 and the outdoor unit portion 2. The avoidance groove 5 is opened downward, to the left and to the right. The avoidance groove 5 is used to avoid the wall so that the window air conditioner 100 can be straddled at the window on the wall.

[0033] Among them, Figure 2-Figure 4 As shown, the bottom plate 31 of the connecting part 3 includes a sinking groove 311 and a step portion 312. The sinking groove 311 is arranged at the front side of the step portion 312 and is connected to the step portion 312. The height of the step portion 312 is greater than the height of the groove bottom wall 3111 of the sinking groove 311. The step portion 312 is higher than the top of the back plate 21 of the external unit part 2 and is supported on the top of the back plate 21 of the external unit part 2, so that the step portion 312 can block the top of the back plate 21 of the external unit part 2. The sinking groove 311 is located on the side of the external unit part 2 close to the internal unit part 1. The groove bottom wall 3111 of the sinking groove 311 is lower than the top of the back plate 21 of the external unit part 2 and is arranged adjacent to the back plate 21 of the external unit part 2. A drainage hole 313 is penetrated through the groove bottom wall 3111 of the sinking groove 311.

[0034] It can be understood that when liquid flows into the connection between the connecting part 3 and the external unit part 2, the liquid flowing to the external unit part 2 can be blocked by the step portion 312 to flow along the step portion 312 to the trough portion 311, while the liquid flowing to the connecting part 3 can directly flow into the trough portion 311, and the liquid flowing into the trough portion 311 can flow to the bottom wall 3111 of the trough portion 311 to be discharged to the bottom of the connecting part 3 through the drainage hole 313, thereby avoiding the liquid flowing into the connecting part 3 or the external unit part 2 and causing a short circuit, thereby improving the reliability of the window air conditioner 100.

[0035] According to the window-type air conditioner 100 of the embodiment of the utility model, the bottom wall 3111 of the trough portion 311 is set lower than the top of the back plate 21 of the external unit portion 2, and a drainage hole 313 is provided on the bottom wall of the trough portion 311, so that the liquid flowing into the connection between the connecting portion 3 and the external unit portion 2 can flow to the bottom wall 3111 of the trough portion 311, and be discharged to the bottom of the connecting portion 3 through the drainage hole 313, thereby preventing the liquid from flowing into the connecting portion 3 or the external unit portion 2 and causing a short circuit, thereby improving the reliability of the window-type air conditioner 100.

[0036] In some embodiments of the present invention, Figure 4As shown, the sink portion 311 further includes an outer groove wall 3112, which is connected between the groove bottom wall 3111 and the step portion 312, and the outer groove wall 3112 extends obliquely downward in the direction from the step portion 312 to the groove bottom wall 3111. Specifically, the outer groove wall 3112 can be arranged to extend obliquely forward and downward. In this way, when liquid drips onto the step portion 312, the outer groove wall 3112 can guide the liquid so that the liquid can quickly flow from the step portion 312 to the groove bottom wall 3111, so as to be discharged from the drainage hole 313 on the groove bottom wall 3111 to the bottom of the connecting portion 3. Through the above arrangement, the flow speed of the liquid on the step portion 312 can be increased, which is conducive to improving the drainage efficiency.

[0037] In some embodiments of the utility model, a pipeline connecting the inner unit part 1 and the outer unit part 2 is passed through the connecting part 3, and there are multiple drainage holes 313 which are concentrated on one side of the left and right center line 3a of the connecting part 3 in the left and right directions, so that the drainage holes 313 are concentrated on the left or right side of the pipeline to be staggered with the pipeline.

[0038] For example, refer to Figure 5 As shown, a pipeline is passed through the connecting part 3, and the pipeline extends in the front-to-back direction. The pipeline is used to connect the indoor part 1 and the outdoor part 2 so that the window air conditioner 100 can operate normally. For example, the indoor part 1 can supply power to the outdoor part 2 through the pipeline, and the outdoor part 2 can transport outdoor fresh air to the indoor part 1 through the pipeline.

[0039] Among them, the drain holes 313 can be provided in plurality, and in the left-right direction, the plurality of drain holes 313 can be provided to be concentrated on one side of the left-right center line 3a of the connecting portion 3, so that the drain holes 313 are concentrated on the left or right side of the pipeline, so as to be staggered with the pipeline. Exemplarily, the plurality of drain holes 313 can be concentrated on the right side of the left-right center line 3a of the connecting portion 3, and the pipeline can be provided on the left side of the left-right center line 3a of the connecting portion 3. Thus, the probability of liquid contacting the pipeline can be reduced, and the reliability of the window air conditioner 100 can be improved.

[0040] In some embodiments of the present invention, Figure 5 As shown, the length L1 of the sink portion 311 in the left-right direction can be set to be greater than 4 / 5 of the length L of the connecting portion 3 in the left-right direction. For example, the length L1 of the sink portion 311 in the left-right direction can be set to 5 / 6 of the length L of the connecting portion 3 in the left-right direction; or, the length L1 of the sink portion 311 in the left-right direction can be set to 9 / 10 of the length L of the connecting portion 3 in the left-right direction, and the present application does not limit this. As a result, the sink portion 311 can better collect liquid, which is conducive to improving the drainage efficiency of the drainage hole 313.

[0041] At the same time, if Figure 3 and Figure 5 As shown, the width W1 of the sinking groove 311 in the front-to-back direction can be set to be less than 1 / 3 of the distance W between the inner unit part 1 and the outer unit part 2 in the front-to-back direction. For example, the width W1 of the sinking groove 311 in the front-to-back direction can be taken as 1 / 2 of the distance W between the inner unit part 1 and the outer unit part 2 in the front-to-back direction; or, the width W1 of the sinking groove 311 in the front-to-back direction can be taken as 2 / 3 of the distance W between the inner unit part 1 and the outer unit part 2 in the front-to-back direction, and the present application does not impose any restrictions on this. Therefore, without affecting the water collection efficiency of the sinking groove 311, the processing difficulty of the connecting part 3 can be reduced, and the practicality of the window air conditioner 100 is improved.

[0042] In some embodiments of the present invention, the connecting part 3 is rotatably connected to the external unit part 2 via a rotating shaft assembly 4, the rotation axis 4a of the rotating shaft assembly 4 extends in the left-right direction, and includes a rotating shaft top cover 41 extending in the left-right direction, the rotating shaft top cover 41 is connected between the top plate 32 of the connecting part 3 and the top plate 22 of the external unit part 2, and at least a portion of the rotating shaft top cover 41 is located directly above the step portion 312.

[0043] For example, refer to Figure 1-Figure 5 As shown, the external machine part 2 and the connecting part 3 can be arranged to pivotally cooperate with each other through a rotating shaft assembly 4, and the rotation axis 4a of the rotating shaft assembly 4 extends in the left-right direction, so that the external machine part 2 can be turned upside down relative to the connecting part 3, thereby allowing the external machine part 2 to be in the installation position and Figure 1 The window air conditioner 100 can be switched between the fixed positions shown in the figure. In the installed position, the outdoor unit part 2 extends in the front-to-back direction, and the outdoor unit part 2 and the connecting part 3 are located above the horizontal plane where the windowsill is located. In this state, it is simpler and more convenient to push the outdoor unit part 2 to the outdoor side. In the fixed position, the outdoor unit part 2 extends in the up-down direction, and most of the outdoor unit part 2 is located below the horizontal plane where the windowsill is located, and can be against the outer wall surface to fix the window air conditioner 100.

[0044] Among them, the shaft assembly 4 includes a shaft top cover 41, which is located at the top of the shaft assembly 4 and extends in the left and right direction. The shaft top cover 41 is connected between the top plate 32 of the connecting part 3 and the top plate 22 of the external machine part 2 to close the gap between the top plate 32 of the connecting part 3 and the top plate 22 of the external machine part 2, and at least part of the shaft top cover 41 is located directly above the step portion 312 so that the shaft top cover 41 can cover the step portion 312.

[0045] Through the above-mentioned arrangement, the liquid flowing into the connection between the connecting part 3 and the external unit part 2 can be reduced, especially the liquid dripping onto the step part 312 can be reduced, thereby reducing the probability of liquid flowing into the external unit part 2 and improving the reliability of the window air conditioner 100.

[0046] In some embodiments of the utility model, the front edge of the rotating shaft top cover 41 has a first water receiving portion 411, the first water receiving portion 411 extends to the bottom of the top plate 32 of the connecting portion 3, and defines a first water receiving groove 4111 with an open top and extending in the left-right direction; wherein, the left and right ends of the first water receiving groove 4111 extend to the left and right ends of the rotating shaft top cover 41, respectively, and the left and right ends of the first water receiving groove 4111 are respectively open, and / or, the bottom wall of the first water receiving groove 4111 is inclined downward from left to right or from right to left.

[0047] For example, refer to Figure 2-Figure 4 As shown, a first water receiving portion 411 is provided at the front edge of the shaft top cover 41. The first water receiving portion 411 extends obliquely forward and upward. The first water receiving portion 411 extends to the bottom of the top plate 32 of the connecting portion 3 and is overlapped and connected with the top plate 32 of the connecting portion 3 to close the gap between the connecting portion 3 and the shaft assembly 4. The first water receiving portion 411 defines a first water receiving groove 4111 open upward. The first water receiving groove 4111 extends in the left-right direction. The first water receiving groove 4111 is used to collect and discharge liquid on the top plate 32 of the connecting portion 3 and the shaft top cover 41. As a result, the probability of liquid entering the connecting portion 3 can be reduced, and the reliability of the window air conditioner 100 is improved.

[0048] The left and right ends of the first water receiving groove 4111 can be respectively extended to the left and right ends of the shaft cover 41, and the left and right ends of the first water receiving groove 4111 are respectively open, so that the liquid in the first water receiving groove 4111 can be directly discharged from the end to the left and right ends of the shaft cover 41. This is conducive to shortening the drainage flow path and simplifying the structure.

[0049] At the same time, the bottom wall of the first water receiving trough 4111 can be set to be tilted downward from left to right or from right to left. Specifically, the bottom wall of the first water receiving trough 4111 can be set to be tilted downward from left to right; or, the bottom wall of the first water receiving trough 4111 can be set to be tilted downward from right to left. In this way, the drainage speed of the first water receiving trough 4111 can be increased, and it is beneficial to eliminate water accumulation.

Through the above arrangement, the drainage speed of the liquid on the top plate 32 of the connecting part 3 can be increased, and the design rationality of the window type air conditioner 100 is improved.

[0051] In some embodiments of the utility model, the rear edge of the shaft top cover 41 has a second water receiving portion 412, the second water receiving portion 412 extends to the bottom of the top plate 22 of the external machine part 2, and defines a second water receiving groove 4121 with an open top and extending in the left-right direction; wherein the left and right ends of the second water receiving groove 4121 extend to the left and right ends of the shaft top cover 41, respectively, and the left and right ends of the second water receiving groove 4121 are respectively open, and / or the bottom wall of the second water receiving groove 4121 is inclined downward from left to right or from right to left.

The second water receiving portion 412 defines a second water receiving groove 4121 open upward, the second water receiving groove 4121 extends in the left-right direction, and the second water receiving groove 4121 is used to collect and discharge liquid on the top plate 22 of the external unit part 2 and the shaft top cover 41. In this way, the probability of liquid entering the external unit part 2 can be reduced, and the reliability of the window air conditioner 100 can be improved.

[0053] The left and right ends of the second water receiving groove 4121 can be respectively extended to the left and right ends of the rotating shaft top cover 41, and the left and right ends of the second water receiving groove 4121 are respectively open, so that the liquid in the second water receiving groove 4121 can be directly discharged from the end to the left and right ends of the rotating shaft top cover 41. This is conducive to shortening the drainage flow path and simplifying the structure.

[0054] At the same time, the bottom wall of the second water receiving trough 4121 can be set to be tilted downward from left to right or from right to left. Specifically, the bottom wall of the second water receiving trough 4121 can be set to be tilted downward from left to right; or, the bottom wall of the second water receiving trough 4121 can be set to be tilted downward from right to left. In this way, the drainage speed of the second water receiving trough 4121 can be increased, and it is beneficial to eliminate water accumulation.
