Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a water channel structure of an air conditioner and an air conditioner. Background Art

[0002] With the development and progress of technology, air conditioners have gradually become an indispensable household appliance in people's daily life. How to improve the energy efficiency of air conditioners has always been a problem that R&D personnel have focused on.

[0003] Taking the front-end mobile air conditioner as an example, since the arrangement direction of the condenser is perpendicular to the direction of the lower air outlet, the condensed water can only drip directly onto the condenser from the side of the air outlet, that is, through the leakage hole in the lower air duct water collecting tray; however, affected by the position of the air outlet, the leakage hole in the lower air duct is often set on the side away from the air outlet, so that when the condensed water drips onto the condenser through the leakage hole, it often drips on one side of the condenser, which can easily cause water on one side of the condenser and no water in most areas of the other side, resulting in uneven cooling of the condenser, insufficient condenser capacity, increased power of the whole machine, and reduced energy efficiency.

[0004] At the same time, for the condensed water that drips onto one side of the condenser, when the air conditioner is used in certain applications, especially in high humidity environments, the heat from the condenser on the side where the condensed water drips cannot evaporate the excess water. The excess water enters the chassis, which may cause water full protection, water leakage, etc. on the entire machine, affecting the user experience. Summary of the invention

[0005] In view of this, the present invention aims to provide a water channel structure of an air conditioner and an air conditioner to solve the problem in the prior art that condensed water in the air conditioner is difficult to drip onto the condenser in a uniform and dispersed manner.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A water channel structure for an air conditioner, wherein the water channel structure is arranged on a rear duct water receiving tray, the water channel structure comprises a water collecting trough, a water passage, and a water distribution channel which are connected in sequence, the water distribution channel being arranged above a condenser in the air conditioner, the water distribution channel extending horizontally to the right side of the condenser, the water distribution channel comprising a bottom plate and a water dividing plate, for dripping condensed water evenly and dispersedly onto the entire condenser; thereby, by arranging the water dividing plate, the condensed water entering the water distribution channel can evenly overflow the water distribution channel and drip evenly and dispersedly onto the entire condenser, and the condensed water will not concentrate on dripping onto one side of the condenser. On the one hand, this ensures that the condenser is cooled evenly, so that the heat of the condenser can fully evaporate the condensed water, which is beneficial to improving energy efficiency; on the other hand, it is beneficial to increase the evaporation amount of the condensed water by the condenser, avoid excess water from entering the chassis, and reduce the probability of water full protection, water leakage, and the like of the entire machine.

[0008] The rear air duct water receiving tray is provided with a water discharge channel below the water passage, and the water distribution channel is provided in the water discharge channel; through the guidance of the water discharge channel, it is ensured that the condensed water can flow into the water distribution channel relatively smoothly.

[0009] A water-passing side wall is arranged on the lower side of the rear air duct water receiving tray, and the bottom plate is connected to the water-passing side wall; thereby, with the help of the guiding and blocking effects of the water-passing side wall, the condensed water falling from the water-passing waterway can completely fall into the water distribution channel.

[0010] A water passing side wall and a splash plate are arranged on the lower side of the rear air duct water collecting tray, and a drainage channel is formed between the water passing side wall and the splash plate; one end of the bottom plate is connected to the water passing side wall, and the other end extends toward the splash plate and is connected to the water dividing plate, and a drainage space is formed between the water dividing plate and the splash plate; therefore, through the arrangement of the splash plate, on the one hand, the water splashed by the condensed water falling into the water distribution channel can be shielded to prevent the splashed water from falling on other components inside the air conditioner; on the other hand, the condensed water evenly distributed by the water dividing plate can, in the process of falling to the condenser, pass through the drainage space and with the help of the guiding and blocking effects of the splash plate, completely fall on the condenser.

[0011] The water-dividing plate is evenly provided with a plurality of water-dividing gaps, and the lowest end of the water-dividing gaps is higher than the upper plate surface of the bottom plate; thus, by evenly providing the water-dividing gaps on the water-dividing plate, the uniform dispersion performance of the condensed water when dripping onto the condenser can be improved; at the same time, when the condensed water just enters the water distribution channel, a small amount of condensed water will not directly fall onto the condenser through the water-dividing gaps, but will gather on the upper plate surface of the bottom plate. As the amount of condensed water increases, the water level of the condensed water gathered on the upper plate surface of the bottom plate gradually rises. When it rises to the lowest end of the water-dividing gaps, the excess condensed water will evenly and dispersedly overflow from each water-dividing gap. This arrangement of the water distribution channel does not need to consider at which end of the water distribution channel the water-passing waterway is set, so that as long as the water-passing waterway is set above the water distribution channel, the effect of evenly and dispersedly dripping the condensed water onto the condenser can be achieved.

[0012] The distance between the lowest end of the water-dividing gap and the upper surface of the bottom plate is recorded as L1, and the distance between the upper end surface of the water-dividing plate and the upper surface of the bottom plate is recorded as L2, L1:L2=0.4~0.7; thus, by limiting the relevant dimensions of the water-dividing gap, it is possible to ensure that condensed water flows out of the water distribution channel at a relatively moderate flow rate per unit time, which is conducive to ensuring smooth drainage of the water distribution channel.

[0013] The distance between any two adjacent water-dividing gaps is the same and is recorded as L4; the distance between the water-dividing gap adjacent to the end of the water distribution channel and the end of the water distribution channel is recorded as L3, L3: L4 = 0.4~0.7; thereby, on the basis of ensuring the uniform dispersion of condensed water, it is also possible to avoid the accumulation or lack of condensed water at the end of the water distribution channel to a certain extent. On the one hand, it ensures the uniform distribution of condensed water in the water distribution channel, and on the other hand, it can avoid the uneven falling of condensed water near the end of the water distribution channel, which is conducive to ensuring that the condensed water drips onto the condenser evenly and dispersedly.

[0014] The water collecting trough is provided with an overflow pipe, and the overflow pipe runs through the bottom wall of the water collecting trough. The water inlet of the water flow channel is provided with a weir flow edge. In the vertical direction, the height of the weir flow edge is smaller than the height of the overflow pipe. On the one hand, the setting of the weir flow edge can prevent the condensed water in the water collecting trough from flowing directly to the water distribution channel, thereby playing a certain buffering role. On the other hand, the setting of the overflow pipe can discharge the excess condensed water from the water collecting trough in time through the overflow pipe when the water flow channel is blocked.

[0015] The water distribution channel and the rear air duct water receiving tray are integrally formed, which is beneficial to ensuring the overall mechanical strength of the rear air duct water receiving tray, while also facilitating processing and forming, thereby helping to reduce production costs and production difficulty.

[0016] An air conditioner comprises the water channel structure; for the air conditioner, by arranging a water distribution plate of the water distribution channel, the condensed water entering the water distribution channel can evenly overflow the water distribution channel and drip onto the condenser in a uniform and dispersed manner, so that the condensed water will not concentrate and drip onto one side of the condenser. On the one hand, it ensures that the condenser is evenly cooled so that the heat of the condenser can fully evaporate the condensed water, which is beneficial to improving energy efficiency. On the other hand, it is beneficial to increase the evaporation amount of the condensed water by the condenser, avoid excess water from entering the chassis, and reduce the probability of water full protection, water leakage, etc. of the whole machine.

[0017] Compared with the prior art, the water channel structure of an air conditioner and the air conditioner described in the present invention have the following advantages:

[0018] The water channel structure of an air conditioner and the air conditioner described in the present invention, by providing a water distribution plate of the water distribution channel, allow the condensed water entering the water distribution channel to evenly overflow the water distribution channel and drip onto the condenser in a uniform and dispersed manner, thereby preventing the condensed water from concentratedly dripping onto one side of the condenser. On the one hand, this ensures uniform cooling of the condenser so that the heat of the condenser can fully evaporate the condensed water, which is beneficial to improving energy efficiency. On the other hand, it is beneficial to increase the evaporation amount of the condensed water by the condenser, avoid excess water from entering the chassis, and reduce the probability of water full protection, water leakage, and the like of the entire machine.

DETAILED DESCRIPTION

[0031] The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the essence of their work to other persons skilled in the art. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] In the prior art, for a mobile air conditioner, water drips directly onto the condenser through the leaking hole in the water receiving tray of the downwind duct, and tends to concentrate on one side of the condenser, making it difficult for the condensed water in the mobile air conditioner to drip onto the condenser evenly and dispersedly, which can easily cause water on one side of the condenser and no water in most areas of the other side. Specifically, in the prior art, condensed water tends to concentrate on the left side of the condenser, which can easily cause water on the left side of the condenser and no water in most areas of the right side.

[0035] In order to solve the problem in the prior art that condensed water in the air conditioner is difficult to drip onto the condenser in a uniform and dispersed manner, this embodiment proposes a water channel structure of the air conditioner, as shown in the attached Figure 1-9As shown, the water channel structure is arranged on the rear air duct water receiving tray 1, and the water channel structure includes a water collecting trough 2, a water passage 4, and a water distribution channel 5 which are connected in sequence. The water distribution channel 5 is arranged above the condenser in the air conditioner, and the water distribution channel 5 extends horizontally to the right side of the condenser. The water distribution channel 5 includes a bottom plate 51 and a water diversion plate 52. One side of the bottom plate 51 is connected to the rear air duct water receiving tray 1, and the other side is connected to the water diversion plate 52. The water diversion plate 52 extends upward.

[0036] Among them, due to the limitations of the location of the water collecting tank 2 and the water passage 4, in the prior art, condensed water is often concentrated in the upper space on the left side of the condenser. In order to prevent the condensed water from dripping onto the left side of the condenser, the present application arranges a water distribution channel 5 with a certain length above the condenser in the air conditioner, which can extend horizontally from the left side of the condenser to the right side of the condenser. On the one hand, the condensed water collected in the upper space on the left side of the condenser can be drained to the right side of the condenser, so that the condensed water can be evenly distributed in the upper space of the entire condenser. On the other hand, by setting a water dividing plate 52, the condensed water evenly distributed in the water distribution channel 5 can evenly overflow the water distribution channel and drip evenly and dispersedly onto the entire condenser.

[0037] Therefore, when the air conditioner is in operation, the condensed water generated by the evaporator falls into the rear duct water collecting tray 1, and flows through the water collecting trough 2 and the water passage 4 in sequence, and enters the water distribution channel 5; by providing the water dividing plate 52, the condensed water entering the water distribution channel 5 can evenly overflow the water distribution channel and drip onto the condenser in a uniform and dispersed manner, so that the condensed water will not concentrate and drip onto one side of the condenser. On the one hand, it ensures that the condenser is cooled evenly, so that the heat of the condenser can fully evaporate the condensed water, which is beneficial to improving energy efficiency. On the other hand, it is beneficial to increase the evaporation amount of the condensed water by the condenser, avoid excess water from entering the chassis, and reduce the probability of water full protection, water leakage, etc. of the whole machine.

[0038] The water passage 4 may be a hole structure penetrating the bottom wall of the water collecting tank 2, or a pipe structure penetrating the bottom wall of the water collecting tank 2, as shown in the attached Figure 7 The water outlet of the water passage 4 is arranged above the water distribution channel 5, so that the condensed water collected in the water collection tank 2 flows directly to the water distribution channel 5 through the water passage 4 under the action of its own gravity.

[0039] The water collecting tank 2 is provided with an overflow pipe 3, and the overflow pipe 3 passes through the bottom wall of the water collecting tank 2. Therefore, when the water passage 4 is blocked and the condensed water in the water collecting tank 2 cannot flow to the water distribution channel 5, it is possible to avoid excessive condensed water accumulating in the water collecting tank 2, and the excess condensed water can be discharged from the water collecting tank 2 in time through the overflow pipe 3.

[0040] A weir flow edge 41 is provided at the water inlet of the water passage 4. In the vertical direction, the height of the weir flow edge 41 is smaller than the height of the overflow pipe 3, so that a small amount of condensed water first gathers in the water collecting tank 2. As the amount of condensed water increases, the water level in the water collecting tank 2 continues to rise. When the water level rises to the upper end of the weir flow edge 41, the excess condensed water flows through the water passage 4 to the water distribution channel 5; if the water passage 4 is blocked, the water level continues to rise, and when it rises to the upper end of the overflow pipe 3, the condensed water is discharged through the overflow pipe 3.

[0041] In order to ensure that the condensed water can flow into the water distribution channel 5 more smoothly, the rear duct water receiving tray 1 is provided with a sewer channel 6 below the water passage 4, and the water distribution channel 5 is arranged in the sewer channel 6. Through the guidance of the sewer channel 6, it is ensured that the condensed water can flow into the water distribution channel 5 more smoothly.

[0042] A water passing side wall 61 is provided on the lower side of the rear air duct water receiving tray 1, and the bottom plate 51 is connected to the water passing side wall 61, so that with the help of the guiding and blocking effects of the water passing side wall 61, the condensed water falling from the water passing waterway 4 can completely fall into the water distribution channel 5.

[0043] Preferably, a water passing side wall 61 and a splash plate 62 are arranged on the lower side of the rear air duct water receiving tray 1, and the water passing side wall 61 and the splash plate 62 are arranged opposite to each other, and a water discharge channel 6 is formed between the water passing side wall 61 and the splash plate 62; wherein one end of the bottom plate 51 is connected to the water passing side wall 61, and the other end extends toward the splash plate 62 and is connected to the water dividing plate 52, and a water discharge space 63 is formed between the water dividing plate 52 and the splash plate 62; after the water in the water distribution channel 5 overflows the water dividing plate 52, all The condensed water evenly flows into the drainage space 63, and falls onto the condenser with the help of the guiding and blocking effects of the splash plate 62. Through the arrangement of the splash plate 62, on the one hand, the water splashed by the condensed water falling into the water distribution channel 5 can be shielded to prevent the splashed water from falling onto other components inside the air conditioner. On the other hand, the condensed water evenly distributed by the water dividing plate 52 can pass through the drainage space 63 and with the help of the guiding and blocking effects of the splash plate 62 in the process of falling into the condenser, and completely fall onto the condenser.

[0044] In order to ensure that the water distribution channel 5 can evenly disperse the condensed water therein, the bottom plate 51, the water diversion plate 52, and the water passing side wall 61 together form a water tank, which plays the role of bearing and containing the condensed water. The water diversion plate 52 is evenly provided with a plurality of water diversion gaps 53, which can improve the uniform dispersion performance of the condensed water when it drops onto the condenser; further, the lowest end of the water diversion gap 53 is higher than the upper plate surface of the bottom plate 51, so that when the condensed water just enters the water distribution channel 5, a small amount of condensed water will not directly fall onto the condenser through the water diversion gap 53, but will gather on the upper plate surface of the bottom plate 51; as the amount of condensed water increases, the water level of the condensed water gathered on the upper plate surface of the bottom plate 51 gradually rises; when it rises to the lowest end of the water diversion gap 53, the excess condensed water will overflow from each water diversion gap 53 in a uniform and dispersed manner. This arrangement of the water distribution channel 5 does not require consideration of at which end of the water distribution channel 5 the water flow channel 4 is arranged, so that as long as the water flow channel 4 is arranged above the water distribution channel 5, the condensed water can be evenly and dispersedly dripped onto the condenser.

[0045] Among them, the water collecting trough 2 is provided with 1-5 water passages 4, which can be evenly arranged in an array above the water distribution channel 5, preferably 3 water passages 4 are arranged; the water dividing plate 52 is evenly provided with 3-7 water dividing gaps 53, preferably 5 water dividing gaps 53; thereby, it is beneficial to further improve the effect of uniform dispersion of condensed water.

[0046] In order to fully ensure the uniform dispersion of condensed water, Figure 8 As shown, the distance between any two adjacent water-dividing gaps 53 is the same and is recorded as L4; according to the needs of actual production and application, L4 is 30-50 mm, preferably, L4=40 mm; the distance between the water-dividing gap 53 adjacent to the end of the water distribution channel 5 and the end of the water distribution channel 5 is recorded as L3, L3:L4=0.4~0.7, preferably L3:L4=1:2, so as to avoid the accumulation or lack of condensed water at the end of the water distribution channel 5 to a certain extent, on the one hand, ensuring the uniform distribution of condensed water in the water distribution channel 5, on the other hand, avoiding the uneven falling of condensed water near the end of the water distribution channel 5, which is conducive to ensuring that the condensed water drips onto the condenser evenly and dispersedly.

[0047] In order to ensure that the water distribution channel 5 can drain smoothly through the water diversion gap 53, as shown in the attached Figure 8As shown, the distance between the lowest end of the water-dividing gap 53 and the upper plate surface of the bottom plate 51 is recorded as L1, and the distance between the upper end surface of the water-dividing plate 52 and the upper plate surface of the bottom plate 51 is recorded as L2, L1:L2=0.4-0.7, preferably L1:L2=1:2; wherein, considering the needs of industrial production and practical application, L1 is 0.8-1.5mm, preferably L1=1mm. Thus, by limiting the relevant dimensions of the water-dividing gap 53, it is possible to ensure that the condensed water flows out of the water distribution channel 5 at a relatively moderate flow rate per unit time, which is conducive to ensuring smooth drainage of the water distribution channel 5.

[0048] Of course, in some extreme cases, the amount of condensed water per unit time is too large, and the water diversion gap 53 is not drained in time, and the water level in the water distribution channel 5 will rise to the upper end surface of the water diversion plate 52. At this time, the excess condensed water will be drained simultaneously through the water diversion gap 53 and the upper end surface of the water diversion plate 52. This is consistent with people's daily life cognition and will not be elaborated here.

[0049] In addition, in order to facilitate production and manufacturing, the water distribution channel 5 and the rear air duct water receiving tray 1 are integrally formed, preferably by injection molding, which is beneficial to ensuring the overall mechanical strength of the rear air duct water receiving tray; at the same time, the water storage tank formed by the bottom plate 51, the water dividing plate 52, and the water passing side wall 61 is preferably a rectangular trough body, which is not only convenient for processing and molding, but also helps to reduce production costs and production difficulty.

[0050] This embodiment also provides an air conditioner, comprising the water channel structure provided in this embodiment.

[0051] In addition, based on the water channel structure-related components and assembly relationships provided in this embodiment, the air conditioner also includes conventional air conditioner components including heat exchange coils, fans, compressors, shells and other structures; in view of the fact that it is prior art, it will not be described in detail here.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
