[0039] In the embodiments of the present disclosure, the character " / " means that the objects before and after it are in an "or" relationship. For example, A / B means A or B.

[0040] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B means that there are three relationships of A or B, or A and B.

[0041] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] In the prior related art, in order to avoid the condensate water in the air conditioner from falling into the casing, a drain pipe and a drain pump are arranged in the air conditioner, and the casing is provided with a corresponding opening. In this way, the drain pipe and the drain pump can discharge the condensate water outside the casing through the corresponding opening, so as to avoid the condensate water affecting the service life of the air conditioner.

[0043] However, after the existing air conditioner is used for a period of time, the drain pipe and the drain pump may be blocked, etc. At this time, if the drain pipe and the drain pump cannot be cleaned and maintained in time, the condensate water may not be discharged in time and may fall into the casing, thereby affecting the service life of the air conditioner. Therefore, when the drain pipe and the drain pump are blocked, the user needs to disassemble the casing of the air conditioner to observe the blocking condition and clean the drain pipe and the drain pump, which is inconvenient to operate.

[0044] As shown in FIG. 1, Figures 1 to 8 The embodiments of the present disclosure provide an air conditioner, and a user can observe the state of the drain device 12 through the observation window 16 and clean the drain device 12 without disassembling the casing 11 of the air conditioner, which is more convenient to operate.

[0045] As shown in FIG. 1, Figures 1 to 8As shown, an embodiment of the present disclosure provides an air conditioner comprising: a housing 11, a drainage device 12, and a blocking end cap 20. The housing 11 is provided with a mounting cavity, and a sidewall of the housing 11 is provided with an observation window 16 communicating with the mounting cavity. The drainage device 12 is installed in the mounting cavity at a position corresponding to the observation window 16. The blocking end cap 20 is provided with a snap-fit ​​portion 23 corresponding to the observation window 16. The snap-fit ​​portion 23 can be snapped onto the edge of the observation window 16 to secure the blocking end cap 20 to the observation window 16.

[0046] Specifically, the housing 11 is further provided with a drain port, which is located on one side of the observation window 16. The drain device 12 communicates with the outside through the drain port to drain condensed water within the housing 11 out of the housing 11 through the drain port. The drain device 12 is installed in a position corresponding to the observation window 16 to facilitate the user to observe or clean the drain device 12 through the observation window 16. The user can attach the plugging portion 23 of the plugging end cap 20 to the edge of the observation window 16 by snapping it onto the edge of the observation window 16; alternatively, the user can detach the plugging portion 23 of the plugging end cap 20 from the edge of the observation window 16 to remove the plugging end cap 20 from the observation window 16.

[0047] In the above embodiment, the size of the blocking end cap 20 is greater than or equal to the size of the observation window 16 , so that when the blocking end cap 20 is engaged with the observation window 16 , the blocking end cap 20 can completely block the observation window 16 .

[0048] If the drain device 12 becomes clogged, the user can disengage the snap-fit ​​portion 23 of the blocking end cap 20 from the edge of the observation window 16 to remove the blocking end cap 20 from the observation window 16. At this point, the user can directly observe the blockage condition and location of the drain device 12 through the observation window 16 and clean the clogged area of ​​the drain device 12 through the observation window 16. After cleaning the drain device 12, the user can snap the snap-fit ​​portion 23 of the blocking end cap 20 onto the edge of the observation window 16 to install the blocking end cap 20 on the observation window 16. At this point, the blocking end cap 20 blocks the observation window 16, preventing debris from entering the housing 11 through the observation window 16 or condensed water in the housing 11 from leaking out of the observation window 16.

[0049] like Figure 1 As shown, in some practical applications, the drainage device 12 can be a drain trough 13, which is connected to a drain outlet. Thus, the air conditioner's condensate-generating component is positioned above the drain trough 13, allowing the condensate to be collected by the drain trough 13. The condensate in the drain trough 13 then flows naturally toward the drain outlet under the influence of gravity and out of the housing 11 through the outlet. In this case, an observation window 16 is positioned above the drain trough 13 to facilitate cleaning.

[0050] like Figure 1As shown in FIG. 1, in some embodiments, the water drainage device 12 includes a water drainage groove 13 and a water drainage pump 14. The water drainage groove 13 is used to receive the condensed water, and the condensed water in the water drainage groove 13 can flow out of the casing 11 through a water drainage port. The water drainage pump 14 includes a water suction pipe and a water drainage pipe 15. The water suction pipe is in communication with the water drainage groove 13, and the water drainage pipe 15 is in communication with the water drainage port. The water drainage pump 14 can actively suck the condensed water in the water drainage groove 13 through the water suction pipe and discharge the condensed water from the water drainage port out of the casing 11 through the water drainage pipe 15, so as to increase the efficiency of discharging the condensed water. At this time, the observation window 16 is arranged between the water drainage groove 13 and the water drainage pump 14, so as to facilitate the user to simultaneously observe the water drainage groove 13 and the water drainage pump 14 through the observation window 16 and clean the water drainage groove 13, the water suction pipe and the water drainage pipe 15 through the observation window 16.

[0051] As shown in FIG. 1, in some embodiments, the water drainage device 12 includes a water drainage groove 13 and a water drainage pump 14. The water drainage groove 13 is used to receive the condensed water, and the condensed water in the water drainage groove 13 can flow out of the casing 11 through a water drainage port. The water drainage pump 14 includes a water suction pipe and a water drainage pipe 15. The water suction pipe is in communication with the water drainage groove 13, and the water drainage pipe 15 is in communication with the water drainage port. The water drainage pump 14 can actively suck the condensed water in the water drainage groove 13 through the water suction pipe and discharge the condensed water from the water drainage port out of the casing 11 through the water drainage pipe 15, so as to increase the efficiency of discharging the condensed water. At this time, the observation window 16 is arranged between the water drainage groove 13 and the water drainage pump 14, so as to facilitate the user to simultaneously observe the water drainage groove 13 and the water drainage pump 14 through the observation window 16 and clean the water drainage groove 13, the water suction pipe and the water drainage pipe 15 through the observation window 16. Figure 2 Figure 5 As shown in FIG. 1, in some embodiments, the water drainage device 12 includes a water drainage groove 13 and a water drainage pump 14. The water drainage groove 13 is used to receive the condensed water, and the condensed water in the water drainage groove 13 can flow out of the casing 11 through a water drainage port. The water drainage pump 14 includes a water suction pipe and a water drainage pipe 15. The water suction pipe is in communication with the water drainage groove 13, and the water drainage pipe 15 is in communication with the water drainage port. The water drainage pump 14 can actively suck the condensed water in the water drainage groove 13 through the water suction pipe and discharge the condensed water from the water drainage port out of the casing 11 through the water drainage pipe 15, so as to increase the efficiency of discharging the condensed water. At this time, the observation window 16 is arranged between the water drainage groove 13 and the water drainage pump 14, so as to facilitate the user to simultaneously observe the water drainage groove 13 and the water drainage pump 14 through the observation window 16 and clean the water drainage groove 13, the water suction pipe and the water drainage pipe 15 through the observation window 16.

[0052] Specifically, the blocking end cover 20 includes a cover plate 21 and a fixing portion 22. The size of the cover plate 21 is greater than that of the observation window 16. The fixing portion 22 is arranged on the side of the cover plate 21 facing the observation window 16, and the size of the fixing portion 22 is smaller than that of the observation window 16. A clamping jaw is arranged on the outer side wall surface of the fixing portion 22 and extends away from the fixing portion 22. There is a gap between the clamping jaw and the cover plate 21.

[0053] The user can cover the blocking end cover 20 on the outside of the observation window 16. At this time, the fixing portion 22 and the clamping jaw of the blocking end cover 20 pass through the observation window 16 to the inside of the casing 11, so that the cover plate 21 of the blocking end cover 20 abuts the outside of the edge of the observation window 16, and the clamping jaw abuts the inside of the edge of the observation window 16, so as to clamp the edge of the observation window 16 between the clamping jaw and the end cover.

[0054] In the above embodiment, the clamping jaw is made of elastic material. In this way, when the user installs the blocking end cover 20, the clamping jaw is elastically deformed under the pushing of the edge of the observation window 16 and naturally restores to abut the inside of the edge of the observation window 16 after the clamping jaw moves to the inside of the observation window 16. When the user dismounts the blocking end cover 20, the clamping jaw is elastically deformed under the pushing of the observation window 16 and moves to the outside of the observation window 16 to be separated from the edge of the observation window 16.

[0055] ​Optionally, the gap between the claw and the cover plate 21 is less than or equal to twice the thickness of the edge of the observation window 16 to avoid shaking when the blocking end cover 20 is clamped on the observation window 16.

[0056] like Figure 3 and Figure 4 As shown, in some embodiments, a first avoidance opening 161 is provided at the edge of the observation window 16, and the shape of the first avoidance opening 161 is corresponding to the shape of the claw; wherein the claw can be inserted into the observation window 16 through the first avoidance opening 161 to be engaged with the edge of the observation window 16.

[0057] Specifically, a first avoidance opening 161 is provided at the edge of the observation window 16. The shape of the first avoidance opening 161 corresponds to the shape of the claw, and the size of the first avoidance opening 161 is greater than or equal to the size of the claw.

[0058] When installing the blocking end cap 20, the user can first place the claw in the position corresponding to the first avoidance opening 161, and then move the claw through the first avoidance opening 161 to the inside of the observation window 16. At this point, the user can rotate the blocking end cap so that the claw engages with the inside edge of the observation window 16. When removing the blocking end cap 20, the user can first rotate the blocking end cap 20 to move the claw to the position corresponding to the first avoidance opening 161, and then move the claw through the first avoidance opening 161 to the outside of the observation window 16.

[0059] In the above embodiment, the first escape opening 161 is provided at the edge of the left or right half of the observation window 16. It is understood that when the blocking end cap 20 is engaged with the observation window 16, the claws may automatically move to the bottom under the action of gravity. In this case, providing the first escape opening 161 at the left or right half of the observation window 16 prevents the claws from detaching from the edge of the observation window 16 after reaching the bottom.

[0060] like Figures 2 to 6 As shown, in some embodiments, the number of claws is at least two, and at least two claws are relatively arranged on both sides of the fixing portion 22; the observation window 16 is provided with at least two first avoidance openings 161, and the two first avoidance openings 161 correspond to the two claws arranged on both sides of the observation window 16 respectively.

[0061] Specifically, the number of latching claws can be two, and the observation window 16 can be provided with two corresponding first avoidance openings 161. The left edge of the observation window 16 is provided with a left first avoidance opening 161, and the right edge of the observation window 16 is provided with a right first avoidance opening 161. The left first avoidance opening 161 and the right first avoidance opening 161 are arranged horizontally. The left half of the blocking end cover 20 is provided with a left latching claw, and the right half of the blocking end cover 20 is provided with a right latching claw. In this way, the user can first move the left and right latching claws to the positions corresponding to the left first avoidance opening 161 and the right first avoidance opening 161, respectively, and then move the left and right latching claws through the left first avoidance opening 161 and the right first avoidance opening 161, respectively, to the inside of the observation window 16. At this point, the user can rotate the blocking end cover 20 so that the left and right latching claws are respectively engaged with the edges of the observation window 16. Such an arrangement can improve the stability of the blocking end cover 20 being engaged with the observation window 16 .

[0062] Similarly, the number of claws can be four, and the observation window 16 is provided with four corresponding first avoidance openings 161. A first avoidance opening 161 is provided in each of the upper, lower, left, and right halves of the observation window 16, and the distance between two adjacent first avoidance openings 161 is the same. The upper, lower, left, and right halves of the sealing end cap 320 are also provided with a claw, and the positions of the claws correspond to the positions of the first avoidance openings 161.

[0063] like Figure 5 As shown, in some embodiments, the air conditioner further includes a sealing ring 26. The sealing ring 26 is provided on a side of the cover plate facing the observation window 16.

[0064] Specifically, the sealing ring 26 is sleeved on the outer side of the fixing portion 22. When the sealing end cap 20 is installed on the observation window 16, the sealing ring 26 is used to seal the gap between the cover plate and the observation window 16 to prevent condensed water from leaking from the gap between the observation window 16 and the cover plate, thereby improving the sealing performance of the sealing end cap.

[0065] like Figure 2 and Figure 5 As shown, in some embodiments, an anti-slip groove 24 is provided on the side of the cover plate facing the observation window 16 , and a sealing ring 26 is installed in the anti-slip groove 24 .

[0066] Specifically, the cover plate 21 is provided with an anti-slip groove 24. The user can install the sealing ring 26 in the anti-slip groove 24 so that part or all of the sealing ring 26 is engaged with the anti-slip groove 24. In this way, the sealing ring 26 can be prevented from falling off the plugging end cap 20, further improving the sealing performance of the plugging end cap 20.

[0067] like Figure 2 and Figure 5As shown, in some embodiments, the outer side wall surface of the fixing portion 22 is provided with a anti-falling protrusion 25, and a gap exists between the anti-falling protrusion 25 and the side wall surface of the cover plate 21 to form an anti-falling groove 24.

[0068] Specifically, a gap exists between the anti-falling protrusion 25 and the cover plate 21 of the blocking end cover 20 to form the anti-falling groove 24. The user can set the sealing ring 26 on the fixing portion 22 of the observation window 16, and make the sealing ring 26 located at the gap between the anti-falling protrusion 25 and the cover plate 21. At this time, the sealing ring 26 is at least partially clamped on the anti-falling protrusion 25 to avoid the sealing ring 26 from falling off the blocking end cover 20.

[0069] As shown in the drawings, Figure 2 As shown, in some embodiments, the outer side wall surface of the fixing portion 22 is provided with a plurality of anti-falling protrusions 25, and the distance between adjacent two anti-falling protrusions 25 is the same.

[0070] Specifically, the plurality of anti-falling protrusions 25 are uniformly arranged along the outer side of the fixing portion 22. In this way, after the user installs the sealing ring 26 on the fixing portion 22, the plurality of anti-falling protrusions 25 can be clamped on the plurality of parts of the sealing ring 26, respectively, to further avoid the sealing ring 26 from falling off.

[0071] Optionally, the edge of the observation window 16 is provided with a second avoiding opening 162, and the second avoiding opening 162 is arranged corresponding to the anti-falling protrusion 25. In this way, when the blocking end cover 20 is installed on the observation window 16, the second avoiding opening 162 can give way to the anti-falling protrusion 25 to avoid the edge of the observation window 16 interfering with the movement of the anti-falling protrusion 25.

[0072] In some embodiments, the size of the observation window 16 is greater than or equal to a preset size.

[0073] Specifically, the observation window 16 is circular, and the diameter of the observation window 16 is greater than or equal to 2 cm. For example, the diameter of the observation window 16 can be 2 cm, 3 cm, 4 cm, 5 cm or 6 cm. In this way, it is more convenient for the user to clean the blocked part of the drainage device 12 through the observation window 16.

[0074] As shown in the drawings, Figure 1 As shown, in some embodiments, the air conditioner further comprises a detection device 31 and a warning device 32. The detection device 31 is used for detecting the blocking condition of the drainage device 12; the warning device 32 is electrically connected with the detection device; wherein, when the detection device detects that the drainage device 12 is blocked, the detection device 31 triggers the warning device 32.

[0075] Specifically, the detection device is installed on the casing 11 of the air conditioner, and is used to detect the clogging condition of the drainage device 12. The warning device is configured as a device capable of generating a warning signal such as sound or light. When the detection device detects that the drainage device 12 is clogged, the detection device can trigger the warning device to prompt the user to clean the drainage device 12 in time.

[0076] In some practical applications, the detection device is a flow rate sensor, which is arranged at the drainage port to obtain the flow rate of the condensed water at the drainage port, and to determine the clogging condition of the drainage device 12 according to the flow rate of the condensed water.

[0077] Optionally, the outer side wall surface of the blocking end cover 20 is further provided with a handle, and the user can rotate the blocking end cover 20 through the handle and install or dismount the blocking end cover 20 on the observation window 16.

[0078] Optionally, the blocking end cover 20 is provided with a left anti-falling protrusion 25 and a right anti-falling protrusion 25, which are respectively arranged on the left half and the right half of the fixed part 22. The outer half of the left anti-falling protrusion 25 is arranged to be inclined to the left side, and the outer half of the right anti-falling protrusion 25 is arranged to be inclined to the right side. Correspondingly, the left half of the observation window 16 is provided with a left second avoiding opening 162 corresponding to the left anti-falling protrusion 25, and the shape of the left second avoiding opening 162 corresponds to the shape of the left anti-falling protrusion 25; the right half of the observation window 16 is provided with a right second avoiding opening 162 corresponding to the right anti-falling protrusion 25, and the shape of the right second avoiding opening 162 corresponds to the shape of the right anti-falling protrusion 25. In this way, when the user rotates the blocking end cover 20 to move the left anti-falling protrusion 25 and the right anti-falling protrusion 25 to positions corresponding to the left second avoiding opening 162 and the right second avoiding opening 162 respectively, the blocking end cover 20 can be installed or dismounted. In this way, the anti-falling protrusion 25 can also play a role in positioning the blocking end cover 20.
