Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art
[0002] When the air conditioner is in operation, some condensation water will be generated on the air duct wall of the base. In order to prevent the condensation water from dripping into the inside of the air conditioner, a drainage groove needs to be set on the base to receive the condensation water.
[0003] The drainage grooves installed on the bases of air conditioners currently on the market are generally horizontal structures. On the one hand, it makes it difficult for the accumulated condensed water in the drainage grooves to be discharged quickly. On the other hand, it causes both ends of the base to be in a wet state for a long time. One end of the base is concentrated with various circuit components including motors. The circuit components are in a humid environment for a long time, and the failure rate is relatively high. Utility Model Content
[0004] The problem solved by the utility model is that the drainage groove arranged on the base of the existing air conditioner is a horizontal structure, which has the problems of low drainage efficiency and high component failure rate.
[0005] In order to solve the above problems, the present invention provides an air conditioner, which can improve drainage efficiency and reduce the failure rate of internal components.
[0006] The embodiment of the present utility model provides a technical solution:
[0007] An air conditioner comprises an upper air duct and a lower air duct, wherein the upper air duct is detachably connected to the lower air duct; the upper air duct is provided with a drainage groove, and the drainage groove extends obliquely downward from a first end in the length direction of the upper air duct to a second end.
[0008] The air conditioner provided by the embodiment of the present invention has a drainage groove provided on the upper air duct, which extends obliquely downward from the first end in the length direction of the upper air duct to the second end, so that the condensed water flowing into the drainage groove can be quickly gathered to the second end under the drainage effect of the drainage groove, thereby preventing the condensed water from accumulating in the drainage groove for a long time and improving the drainage efficiency of the condensed water. In addition, the first end of the upper air duct is kept dry, providing a dry environment for the installation of various circuit components including motors, thereby reducing the failure rate of the components. In addition, the drainage groove is provided on the upper air duct, which can prevent the condensed water from reaching the lower air duct and avoid the leakage of condensed water when the lower air duct is disassembled. Therefore, the air conditioner provided by the embodiment of the present invention can improve the drainage efficiency and reduce the failure rate of internal components.
[0009] In an optional embodiment, the upper air duct further has a blade cavity for installing a cross-flow blade. There are multiple drainage grooves, and at least two of the multiple drainage grooves are respectively arranged on the front and rear sides of the blade cavity.
[0010] At least two drainage grooves are respectively arranged on the front and rear sides of the fan blade cavity. The drainage groove arranged on the front side of the fan blade cavity can receive the condensed water generated on the front side of the air conditioner heat exchanger, and the drainage groove arranged on the rear side of the fan blade cavity can receive the condensed water generated on the rear side of the heat exchanger, thereby obtaining a better drainage effect.
[0011] In an optional embodiment, the upper air duct also has a confluence groove, which is arranged at the second end and extends from the front side to the rear side of the fan blade cavity. Multiple drainage grooves are connected to the confluence groove, and a drainage port is provided on the groove wall of the confluence groove.
[0012] The confluence trough is arranged at the second end, and the lower end of multiple drainage troughs is connected to the confluence trough. The condensed water in each drainage trough quickly flows into the confluence trough, and then is discharged to the outside of the air conditioner through the drain port arranged on the wall of the confluence trough, thereby realizing efficient drainage.
[0013] In an optional embodiment, the drain outlet is provided on the bottom wall of the confluence trough, and the bottom wall of the confluence trough extends obliquely downward from any end of the confluence trough to the drain outlet.
[0014] From either end of the confluence trough to the drain outlet, the bottom wall of the confluence trough extends downward at an angle. That is, whether the condensed water flows into the confluence trough from the drain trough on the front side of the air duct or the condensed water flows into the confluence trough from the drain trough on the rear side of the air duct, it can quickly flow into the drain outlet under the guiding action of the bottom wall of the confluence trough, further improving the drainage efficiency.
[0015] In an optional embodiment, the drainage groove includes a plurality of branch grooves arranged in sequence in the length direction of the upper air duct, and the heights of the plurality of branch grooves decrease in sequence from the first end to the second end.
[0016] The multiple branch grooves form a successive height difference, thereby realizing segmented acceleration of the condensed water, further increasing the speed at which the condensed water flows from the first end to the second end, thereby further improving the drainage efficiency.
[0017] In an optional embodiment, the connection position between any two adjacent drainage grooves forms a step structure.
[0018] The connection positions of adjacent drainage grooves form a step structure, which can prevent condensed water from flowing back under special circumstances and ensure that the drainage process is stable and reliable.
[0019] In an optional embodiment, the plurality of branch segment grooves extend obliquely downward from the first end to the second end.
[0020] The multiple branch grooves also extend downwardly at an angle, which can prevent condensed water from adhering to the various branch grooves and achieve a better drainage effect.
[0021] In an optional embodiment, the upper air duct further has a motor mounting portion, and the motor mounting portion is arranged at the first end.
[0022] The motor and other circuit components are all arranged at the first end, and the drainage groove is higher at the first end, so that the first end remains dry, thereby keeping the circuit components in a dry environment, reducing the failure rate and improving the stability of the air conditioner operation.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0031] See also Figure 1 , Figure 1 Shown is a schematic structural diagram of the upper air duct 100 of the air conditioner provided in this embodiment at a first viewing angle.
[0032] The air conditioner provided in this embodiment includes an upper duct 100, a lower duct 200, and a middle frame. The upper duct 100 and the lower duct 200 are detachably connected to form the base structure of the air conditioner, and the middle frame cover is mounted on the base structure. The upper duct 100 has a drainage groove 110, which extends obliquely downward from a first end 120 along the length of the upper duct 100 to a second end 130.
[0033] It is understood that the drain groove 110 is provided on the inner wall of the upper air duct 100 to receive condensed water on the inner wall. The drain groove 110 extends obliquely downward from the first end 120 to the second end 130 of the upper air duct 100, meaning that the height of the drain groove 110 gradually decreases from the first end 120 to the second end 130 of the upper air duct 100.
[0034] In actual application, after the condensed water on the upper air duct 100 flows into the drainage groove 110, it flows toward the end of the drainage groove 110 corresponding to the second end 130 of the upper air duct 100 under the action of gravity, that is, it flows to the end of the drainage groove 110 with a lower height, and leaves the drainage groove 110 from this end, thereby achieving fast and efficient drainage.
[0035] Furthermore, because the drain groove 110 is higher than the end corresponding to the first end 120 of the upper air duct 100, condensed water that enters the drain groove 110 rarely stays at this end, maintaining a dry state at the first end 120 of the upper air duct 100. In practical applications, various circuit components, including the motor, can be arranged at the first end 120 of the upper air duct 100, that is, in a dry environment, thereby reducing the failure rate and extending the service life of the air conditioner.
[0036] It should be noted that the orientation in this embodiment is defined based on the condition that the air conditioner is mounted on a wall. When the air conditioner is mounted on a wall, the length of the upper air duct 100 is substantially horizontal, and the drainage groove 110 extends obliquely downward from the first end 120 to the second end 130. In other words, the end of the drainage groove 110 at the second end 130 is closer to the ground.
[0037] In this embodiment, the upper air duct 100 further has a blade cavity 140 , and there are a plurality of drainage grooves 110 , at least two of which are respectively disposed at the front and rear sides of the blade cavity 140 .
[0038] It can be understood that the fan cavity 140 is used to install cross-flow fan blades and wind guide blades, etc. The heat exchanger of the air conditioner is at the air inlet end of the fan cavity 140, and the air conditioner is provided with an air outlet at the air outlet end of the fan cavity 140. In actual application, under the action of the cross-flow fan blades, the air flow flows into the air conditioner from the air inlet end, passes through the fan cavity 140 and then flows out from the air outlet.
[0039] In this embodiment, drainage grooves 110 are provided on the front and rear sides of the fan blade cavity 140. The drainage groove 110 provided on the front side of the fan blade cavity 140 is used to receive the condensed water on the front side of the heat exchanger, and the drainage groove 110 provided on the rear side of the fan blade cavity 140 is used to receive the condensed water on the rear side of the heat exchanger, thereby preventing the condensed water from entering the interior of the air conditioner and obtaining a better drainage effect.
[0040] Please refer to Figure 2 and Figure 3 , Figure 2 The figure shows the structure of the upper air duct 100 at a second viewing angle. Figure 3 Shown Figure 2 A magnified schematic diagram of area A in the middle.
[0041] In order to achieve rapid discharge of condensed water in the drainage groove 110, in fact, the upper air duct 100 also has a confluence groove 150, which is arranged at the second end 130 and extends from the front side to the rear side of the fan blade cavity 140. Multiple drainage grooves 110 are connected to the confluence groove 150, and a drainage port 151 is provided on the groove wall of the confluence groove 150.
[0042] In actual application, after the condensed water on the front inner wall of the upper air duct 100 and the condensed water on the rear inner wall flow into the corresponding drainage groove 110, since the drainage groove 110 extends downward at an angle from the first end 120 to the second end 130 of the upper air duct 100, under the guidance of the drainage groove 110, the condensed water inside each drainage groove 110 quickly flows into the confluence groove 150 at the second end 130 of the upper air duct 100, and then flows out of the air conditioner through the drain port 151 set on the groove wall of the confluence groove 150, thereby realizing the rapid discharge of the condensed water.
[0043] Furthermore, the drain port 151 is provided on the bottom wall of the confluence trough 150 , and the bottom wall of the confluence trough 150 extends obliquely downward from any end of the confluence trough 150 to the drain port 151 .
[0044] In other words, the bottom wall of the confluence trough 150 consists of two sections connected at an angle, and the drain outlet 151 is located at the intersection of the two sections. In actual use, condensed water flowing into the confluence trough 150 from either the front or rear drain troughs 110 can be quickly diverted into the drain outlet 151 by the bottom wall of the confluence trough 150, preventing condensed water from accumulating in the confluence trough 150 and further improving drainage efficiency.
[0045] Please refer to Figure 4 , Figure 4 Shown Figure 2 Schematic diagram of the enlarged area B.
[0046] In this embodiment, the drainage groove 110 includes a plurality of branch grooves 111 arranged in sequence in the length direction of the upper air duct 100. From the first end 120 to the second end 130, the heights of the plurality of branch grooves 111 decrease successively, and the connection position of any two adjacent drainage grooves 110 forms a step structure 112.
[0047] It can be understood that, from the first end 120 to the second end 130 of the upper air duct 100, a plurality of branch grooves 111 sequentially form a plurality of step structures 112 that decrease in step. Each time the condensed water flows through any step structure 112, it is greatly accelerated, which can significantly increase the speed of the condensed water flowing to the second end 130.
[0048] Furthermore, the presence of the multiple step structures 112 prevents reverse flow of condensed water in the drainage trough 110, ensuring a more stable and reliable drainage process. In addition to the multiple branch troughs 111 having successively lower heights, the multiple branch troughs 111 extend obliquely downward from the first end 120 to the second end 130.
[0049] Since the multiple branch segment grooves 111 are all arranged at an angle, the condensed water flowing into the drainage groove 110 is accelerated by the current branch segment groove 111, and then flows into the next adjacent branch segment groove 111 in an accelerated state. After being further accelerated by the height difference of the step structure 112, the flow rate of the condensed water is further increased, so that it can quickly flow into the confluence groove 150 at the second end 130 of the upper air duct 100.
[0050] In this embodiment, the upper air duct 100 further includes a motor mounting portion 160 disposed at the first end 120. In practice, a motor is mounted on the motor mounting portion 160 to drive the crossflow blades within the blade cavity 140. Because the first end 120 is always dry, the motor is always in a dry environment, resulting in a lower failure rate and long-term stable operation.
[0051] In fact, in addition to the motor, various other circuit elements of the air conditioner provided in this embodiment are also concentrated at the first end 120 of the upper air duct 100, so that the air conditioner can operate stably for a long time and have a longer service life.
[0052] In the air conditioner provided in this embodiment, since the drain groove 110 is provided on the upper air duct 100, it can prevent condensed water from flowing into the lower air duct 200, shortening the travel distance of the condensed water. Furthermore, when the lower air duct 200 is removed to clean the structure in the blade chamber 140, the condensed water in the drain groove 110 can be prevented from leaking out.
[0053] It can be seen that the air conditioner provided by the embodiment of the present invention has a drainage groove 110 provided on the upper air duct 100 that extends obliquely downward from the first end 120 in the length direction of the upper air duct 100 to the second end 130, so that the condensed water flowing into the drainage groove 110 can quickly flow into the confluence groove 150 arranged at the second end 130 under the drainage effect of the drainage groove 110, and quickly drain out to the outside through the drainage port 151 of the confluence groove 150. This prevents the condensed water from accumulating in the drainage groove 110 for a long time, thereby improving the efficiency of condensed water discharge. In addition, the first end 120 of the upper air duct 100 is kept dry, providing a dry environment for the installation of various circuit components including the motor, thereby reducing the failure rate of the components.
[0054] Therefore, the air conditioner provided by the embodiment of the present invention can improve drainage efficiency, reduce the failure rate of internal components, and have a longer service life.
[0055] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
