The water receiving trough can collect the condensate produced by the second heat exchanger. The bottom of the water pumping trough is lower than the lowest point of the bottom of the water receiving trough. Under the action of gravity, the water in the water receiving trough can flow past the bottom of the clearance channel and then flow towards the water pumping trough. Furthermore, the bottom height of the water receiving trough gradually decreases from the end away from the water pumping trough to the end closer to the water pumping trough, so that all the condensate in the water receiving trough can flow smoothly towards the water pumping trough, so that the condensate in the flow channel can be collected in the water pumping trough, and then the water collected in the water pumping trough can be pumped onto the first heat exchanger. This avoids the accumulation of condensate at the bottom of the second heat exchanger, and uses the condensate to cool and exchange heat for the first heat exchanger, consuming the water in the flow channel, reducing the need for drainage pipes for condensate discharge, and also promoting the heat exchange system formed by the first and second heat exchangers, thereby improving the heat exchange efficiency of the integrated air conditioner.

[0059] This utility model proposes a disc body.

[0060] Please refer to Figure 1 , Figure 2 and Figure 8 In one embodiment of the present invention, the plate is applied to an integrated air conditioner. The integrated air conditioner includes a first heat exchanger 200 and a second heat exchanger 300 distributed in parallel. The plate 100 is provided with a flow channel 110. The flow channel 110 includes a water receiving trough 111 and a water discharging trough 112 that are connected to each other. The water receiving trough 111 is located below the second heat exchanger 300, and the water discharging trough 112 is located below the first heat exchanger 200.

[0061] Among them, the bottom of the water-spraying trough 112 is lower than the lowest point of the bottom of the water-receiving trough 111, and the height of the bottom of the water-receiving trough 111 gradually decreases from the water-receiving trough 111 to the water-spraying trough 112.

[0062] The technical solution of this utility model involves setting a flow channel 110 in the plate body 100. A water receiving trough 111 is provided at the lower part of the flow channel 110 corresponding to the second heat exchanger 300, and a water discharging trough 112 is provided at the lower part of the first heat exchanger 200. The water receiving trough 111 can collect the condensate generated by the second heat exchanger 300. The bottom of the water discharging trough 112 is lower than the lowest point of the bottom of the water receiving trough 111. Under the action of gravity, the water accumulated in the water receiving trough 111 can flow through the clearance channel 150 and then flow downwards towards the water discharging trough 112. Furthermore, the bottom of the water receiving trough 111 at the end furthest from the water discharging trough 112 is higher than the bottom of the end closest to the water discharging trough 112. As the temperature gradually decreases, the condensate in the water collection tank 111 can flow smoothly into the water discharge tank 112, allowing the condensate in the flow channel 110 to collect in the water discharge tank 112. The collected water in the water discharge tank 112 is then discharged onto the first heat exchanger 200, thus preventing condensate from accumulating at the bottom of the second heat exchanger 300. The condensate is used to cool and exchange heat with the first heat exchanger 200, consuming the water in the flow channel 110. This reduces the need for drainage pipes to discharge condensate and also promotes the heat exchange system formed by the first heat exchanger 200 and the second heat exchanger 300, improving the heat exchange efficiency of the integrated air conditioner.

[0063] It should be noted that the bottom of the water trough 112 can be the lowest point of the flow channel 110, or it can be located upstream or downstream of the water trough 112 in the direction of water flow in the flow channel 110. At least, the water accumulated in the receiving trough 111 can flow towards the water trough 112 in a timely manner. Only after all sections of the flow channel 110 except for the receiving trough 111 have accumulated water can the receiving trough 111 have the possibility of water accumulation. In this way, the flow direction of the flow channel 110 of the plate 100 is clear, forming an effective zone for water collection, diversion, and convergence. This can effectively reduce the possibility of water accumulation at the bottom of the second heat exchanger 300, improve the utilization rate of condensate and the thermal efficiency of the integrated air conditioner, and also reduce the possibility of condensate overflow. In one embodiment, when the integrated air conditioner is cooling, the first heat exchanger 200 is configured as a condenser and the second heat exchanger 300 is configured as an evaporator. In another embodiment, when the integrated air conditioner is heating, the first heat exchanger 200 is configured as an evaporator and the second heat exchanger 300 is configured as a condenser. This technical solution focuses on the cooling operation of the integrated air conditioner.

[0064] In one embodiment, please refer to 1 to Figure 3The integrated air conditioner also includes a water pumping device 400, which is disposed on the panel 100 and located between the water pumping tank 112 and the first heat exchanger 200. The water pumping device 400 pumps water from the water pumping tank 112 onto the surface of the first heat exchanger 200. Due to the heat absorption effect of water evaporation, some heat is carried away from the first heat exchanger 200, especially the lower-temperature condensate, which helps to lower the temperature of the first heat exchanger 200, thereby improving the heat dissipation efficiency of the first heat exchanger 200. This allows the air conditioner to reach the set temperature more quickly during the cooling process, improving the overall cooling efficiency. Without loss of generality, the water-spraying device 400 includes a water-spraying wheel 410 and a drive motor. The drive motor is mounted on the disc body 100 and drives the water-spraying wheel 410 to rotate, spraying the condensate in the water-spraying tank 112 towards the first heat exchanger 200. This utilizes the condensate to promote cooling of the first heat exchanger 200 while also consuming the condensate, reducing the need for pipes to drain the condensate. Alternatively, in other embodiments, a water spray structure can be installed at the bottom of the water-spraying tank 112 to spray the accumulated water in the tank 112 towards the first heat exchanger 200.

[0065] Regarding the bottom structure of the water receiving tank 111, in one embodiment, please refer to... Figures 2 to 4 Along the flow direction of the channel 110, the bottom wall of the receiving trough 111 extends downwards at an angle α, where α satisfies: 0.1° ≤ α ≤ 3°. This means the bottom wall of the receiving trough 111 provides a clear flow direction for the condensate, ensuring it flows smoothly along the bottom wall towards the drainage trough 112, preventing accumulation within the receiving trough 111. Specifically, the larger the angle α is in the direction closer to the drainage trough 112, the shorter the residence time of the condensate in the receiving trough 111, thus reducing the risk of condensate accumulation. Regarding the angle α, a smaller angle results in a slower flow velocity of the condensate along the bottom wall, but ensures continuity and stability of the flow; a larger angle increases the flow velocity and drainage efficiency, but an excessively large angle may cause the condensate to generate a large impact force during flow, potentially affecting the drainage trough 112 or the drainage system. Therefore, selecting an appropriate α value within the range of 0.1° to 3° can balance the flow rate of condensate and drainage efficiency, while ensuring the stability and reliability of the system. α can take values ​​such as 0.1°, 0.5°, 1°, 1.5°, 2°, 2.6°, and 3°.

[0066] In another embodiment, along the flow direction of the channel 110, the bottom wall of the receiving tank 111 is configured with multiple stepped sections, the height of which decreases sequentially towards the water-receiving tank 112. It can be understood that the stepped bottom wall of the receiving tank 111 guides the condensate in segments during its flow, with each stepped section acting as a small guiding platform, helping the condensate to be distributed more evenly on the bottom wall and avoiding localized accumulation. Simultaneously, the stepped sections can slow down the flow rate of the condensate to a certain extent, helping it to flow more smoothly and reducing the impact force caused by excessive flow velocity, thus protecting the channel 110. Of course, the sequential decrease in height of the stepped sections towards the water-receiving tank 112 allows the condensate to flow more smoothly towards the water-receiving tank 112, helping to improve the efficiency of the condensate flow within the channel 110.

[0067] In one embodiment, please refer to Figure 1 and Figure 2 The tray 100 is configured as the chassis of an integrated air conditioner. It can be understood that the tray 100 integrates the installation of the integrated air conditioner and the functions of receiving and channeling condensate water, improving the ease of assembly. Simultaneously, the tray 100, as a chassis, integrates the supporting structure of the integrated air conditioner, which helps ensure the structural stability of the tray 100, thereby ensuring the structural strength of the flow channel 110. This, in turn, ensures that condensate water can stably collect along the flow channel 110 into the water tray 112 for heat dissipation by the first heat exchanger 200. Alternatively, in another embodiment, the tray 100 is configured as the water receiving tray of the integrated air conditioner. It is understandable that the panel 100 is installed on the chassis of the integrated air conditioner. The chassis is the load-bearing structure of the integrated air conditioner. Separating the panel 100 and the chassis reduces the structural complexity of the chassis, facilitates the molding of the panel 100 and the chassis, and also makes it easier to adjust the setting position of the panel 100, ensuring that the flow channel 110 of the panel 100 can be aligned with the lower part of the second heat exchanger 300 and the first heat exchanger 200.

[0068] In one embodiment, please refer to Figure 2 and Figure 3The water receiving tank 111 is provided with supporting ribs 113, which abut against the lower part of the second heat exchanger 300. The supporting ribs 113 create a gap between the lower part of the second heat exchanger 300 and the bottom of the water receiving tank 111, preventing condensate from soaking the second heat exchanger 300 and also preventing the second heat exchanger 300 from obstructing water flow in the water receiving tank 111. Simultaneously, the supporting ribs 113 help to clearly define the structure of the plate 100 supporting the second heat exchanger 300, facilitating adjustments to position the supporting ribs 113 at the bottom of the second heat exchanger 300 to ensure installation stability. Generally, the supporting ribs 113 are elongated and extend along the extension direction of the water receiving tank 111; alternatively, multiple supporting ribs 113 may be arranged and distributed along the extension direction of the water receiving tank 111. Of course, in other embodiments, the bottom of the water receiving tank 111 can be recessed, and a flow guiding structure can be provided at the opening of the water receiving tank 111, with the bottom of the second heat exchanger 300 abutting against the opening of the water receiving tank 111.

[0069] Regarding the structural configuration of the water receiving tank 111 and the second heat exchanger 300, in one embodiment, please refer to... Figure 2 and Figure 3 The water receiving tank 111 is U-shaped, with the bottom of one end lower than the bottom of the other end, and the lower end of the water receiving tank 111 is connected to the water discharge tank 112. It should be noted that the U-shaped design of the second heat exchanger 300 increases its heat absorption and cooling efficiency. Correspondingly, it also helps the condensate from the second heat exchanger 300 to be evenly distributed within the water receiving tank 111, increasing the efficiency of condensate dripping from the second heat exchanger 300 and dispersing the dripping position of the first heat exchanger 200. This reduces the risk of condensate overflowing from the water receiving tank 111 and ensures the stability and reliability of condensate collection in the water receiving tank 111. Furthermore, the bottom of one end of the water receiving tank 111 is lower than the bottom of the other end, and the water receiving tank 111 is connected to the water discharge tank 112 at one end. This clarifies the flow direction of the condensate in the water receiving tank 111, avoiding condensate stagnation and accumulation. It ensures that the condensate can be smoothly discharged from the water receiving tank 111 to the water discharge tank 112, and also avoids leakage problems caused by condensate being blocked and accumulating in the water receiving tank 111 due to unclear flow direction. Of course, in other embodiments, the water receiving tank 111 can also be configured as multiple independent tank segments at the bottom of the second heat exchanger 300, and each tank segment can be connected to the water discharge tank 112 independently or in parallel, depending on the structure of the plate body 100.

[0070] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 8The flow channel 110 also includes a drainage area 114, the bottom of which is the lowest point of the flow channel 110. A drain plug 120 is provided in the drainage area 114. It is understood that if there is water accumulation in the flow channel 110, there will also be at least some water accumulation in the drainage area 114. Even with very little water accumulation, the water will accumulate in the drainage area 114, allowing the water on the panel 100 to drain smoothly under gravity, thus preventing water accumulation. Simultaneously, when maintenance of the integrated air conditioner is required, removing the drain plug 120 will empty the water in the drainage area 114, thus emptying the flow channel 110 and preventing overflow or damage to electronic components during maintenance. Alternatively, after a period of use, removing the drain plug 120 will remove debris from the flow channel 110, ensuring smooth flow of condensate from the water collection tray 111 to the drain trough 112. Of course, in other embodiments, the water accumulated in the flow channel 110 can also be sucked up and discharged by a water pump or the like.

[0071] Furthermore, in this embodiment, please refer to Figure 2 and Figure 4 In the flow channel 110, the bottom of the water-filling trough 112 is higher than the bottom wall of the drainage area 114. It can be understood that when condensate flows naturally in the flow channel 110, it will first flow towards the drainage area 114, ensuring that condensate is preferentially discharged and avoiding unnecessary accumulation in the water-filling trough 112 or other non-drainage areas 114. Simultaneously, since the bottom wall of the drainage area 114 is lower than the bottom of the water-filling trough 112, impurities in the flow channel 110 will preferentially accumulate at the bottom of the drainage area 114, reducing the probability of impurities being blown towards the first heat exchanger 200 and ensuring the operational stability of the first heat exchanger 200. Furthermore, although the bottom of the water-filling trough 112 is higher than the bottom wall of the drainage area 114, the water-filling trough 112 will also preferentially accumulate condensate from the receiving trough 111, thus facilitating the water-filling operation and ensuring sufficient water volume for cooling the first heat exchanger 200. Without loss of generality, the water trough 112 is configured in the flow channel 110 at a position only higher than the drainage area 114, to ensure that condensate can preferentially accumulate in the water trough 112, thereby supplying the first heat exchanger 200 with water and cooling it, ensuring efficient condensate consumption. Of course, in other embodiments, the drainage area 114 can also be configured at the position of the water trough 112, with the bottom of the water trough 112 being the lowest point of the flow channel 110.

[0072] Regarding the location of the drainage zone 114, in one embodiment, please refer to... Figure 2 and Figure 8The drainage zone 114 is located between the water inlet trough 112 and the water outlet trough 111. It should be noted that there is a certain distance between the water inlet trough 111 and the water inlet trough 112, and the integrated air conditioner has relatively few components in this flow section. Placing the drainage zone 114 in this location ensures sufficient space for its installation, reduces modifications to the integrated air conditioner, and avoids the drainage zone 114 occupying additional installation space, resulting in a more compact and efficient overall design. Simultaneously, as the main channel for condensate, the drainage zone 114 helps impurities in the condensate accumulate there, reducing impurities flowing with the condensate to the water inlet trough 112 and ensuring the stability of the first heat exchanger 200. Furthermore, it ensures that impurities in the flow channel 110 preferentially and mostly accumulate in the drainage zone 114, allowing them to be discharged outside the integrated air conditioner after the drain plug 120 is removed, improving the ease of cleaning. Of course, in other embodiments, the drainage area 114 may also be located downstream of the water trough 112 in the flow channel 110.

[0073] In one embodiment, please refer to Figure 2 and Figure 4 The height H1 between the bottom of the water trough 112 and the bottom wall of the drainage area 114 satisfies: 0.05mm ≤ H1 ≤ 10mm. Within this range, H1 ensures the bottom of the water trough 112 is at a low position, allowing condensate in the flow channel 110 to flow preferentially to the drainage area 114 without excessive condensate accumulation in the drainage area 114. This allows the water trough 112 to accumulate condensate promptly, enabling timely drainage of condensate to the water trough 112 during the operation of the air conditioner, thus facilitating the use of the first heat exchanger 200 to consume the condensate. H1 can be 0.05mm, 0.1mm, 0.8mm, 1mm, 3mm, 5mm, 6mm, 8mm, or 10mm, etc. Of course, depending on the size and specifications of the integrated air conditioner, the bottom of the water trough 112 can be more than 10mm higher than the bottom wall of the drainage area 114.

[0074] In one embodiment, please refer to Figure 1 and Figure 2The integrated air conditioner also includes a fan wheel, the air intake side of which is opposite to the first heat exchanger 200. The flow channel 110 also includes a return water tank 115, which is disposed between the water inlet tank 112 and the fan wheel, and the return water tank 115 is connected to the water inlet tank 112. Understandably, in the cooling state, the water receiving tank 111 guides the condensate to the water dissipation tank 112, and the water dissipation device 400 sprays water onto the first heat exchanger 200. The impeller continues to operate, dissipating heat from the first heat exchanger 200 outwards. The water sprayed onto the first heat exchanger 200 by the water dissipation device 400 also moves towards the suction side of the impeller due to the impeller's adsorption effect. Some of the condensate falls between the first heat exchanger 200 and the impeller into the return water tank 115, and then flows back from the return water tank 115 to the water dissipation tank 112, forming a condensate recovery path. This prevents condensate from scattering in other parts of the pan 100, fully utilizes the condensate, improves the working efficiency of the first heat exchanger 200, and effectively reduces the amount of condensate accumulating in the pan 100. Without loss of generality, the return water tank 115 can be directly connected to the water inlet tank 112, or it can be directly connected to a flow section other than the water inlet tank 112, such as the drainage area 114, and then connected to the water inlet tank 112 through this flow section, so as to achieve the purpose of circulating condensate to the water inlet tank 112. Of course, in other embodiments, the water inlet tank 112 can also cover the gap between the first heat exchanger 200 and the impeller, so that the condensate moving towards the suction side of the impeller can fall back into the water inlet tank 112.

[0075] Furthermore, in this embodiment, please refer to Figure 2 and Figure 4The flow channel 110 also includes a drainage area 114, which is located upstream of the water-collecting trough 112. A return water inlet 116 is provided on the side wall of the return water trough 115, which is connected to the drainage area 114 via the return water inlet 116. The lowest point of the return water inlet 116 is higher than the bottom of the water-collecting trough 112. The drainage area 114's location upstream of the water-collecting trough 112 ensures that condensate flows first to the drainage area 114 in the flow channel 110. When the drainage area 114 reaches a certain water level, excess condensate continues to flow along the flow channel 110, at which point the water-collecting trough 112, as a secondary priority water accumulation area, begins to accumulate condensate. The return water tank 115 is connected to the drainage area 114 via a return water inlet 116, which is higher than the bottom of the water inlet tank 112, forming a return water circulation path. When the water level in the drainage area 114 rises to a certain height, the condensate in the drainage area 114 preferentially flows to the water inlet tank 112 to meet the cooling needs of the first heat exchanger 200 and consume condensate. In addition, the condensate from the receiving tank 111 first flows through the drainage area 114, where impurities can settle, reducing the impurity content of the condensate in the water inlet tank 112, reducing the impact on the heat dissipation of the first heat exchanger 200, and ensuring the operational stability of the first heat exchanger 200. Of course, in other embodiments, the drainage area 114 can also be located downstream of the water trough 112. After the condensate flows through the water trough 112, it flows to the drainage area 114. After the condensate in the drainage area 114 accumulates to a certain extent, the condensate will preferentially accumulate in the water trough 112 for consumption by the first heat exchanger 200. Correspondingly, the return water trough 115 can be connected to the flow section connecting the water receiving trough 111 and the water trough 112, or connected to the drainage area 114, or directly connected to the water trough 112.

[0076] Specifically, in this embodiment, please refer to Figure 2 and Figure 4The lowest point of the return water inlet 116 is H2 above the bottom wall of the drainage area 114, where H2 satisfies: 3mm ≤ H2 ≤ 25mm. Referring to the above description of H1, and limiting the lowest point of the return water inlet 116 to be above the bottom of the water trough 112, it can be seen that limiting H2 within the above range ensures that after condensate accumulates to a certain level in the drainage area 114, it preferentially flows to the water trough 112, allowing the water trough 112 to continuously consume the condensate, and ensuring that the condensate collected in the return water trough 115 can flow back to the drainage area 114. Simultaneously, limiting the height of H2 to less than or equal to 25mm helps reduce the occurrence of water hammer, thereby reducing the impact of condensate backflow from the return water trough 115 on the water flow from the drainage area 114 towards the water trough 112, or preventing the stirring of impurities settled in the drainage area 114, thus ensuring the speed at which condensate from the drainage area 114 flows into the water trough 112. It is understood that H1 is less than H2. For example, when H1 is 3mm, H2 is 4mm or 6mm, etc.; when H1 is 6mm, H2 is 10mm or 15mm, etc.; and when H1 is 10mm, H2 is 15mm or 20mm, etc. Here, the value of H2 can be 3mm, 6mm, 10mm, 15mm, 18mm, 21mm, 25mm, etc. Of course, in other embodiments, depending on the size of the integrated air conditioner, the lowest point of the return water inlet 116 can be more than 25mm higher than the bottom wall of the drainage area 114.

[0077] In one embodiment, please refer to Figures 5 to 7 The integrated air conditioner also includes a fan wheel 500, and the flow channel 110 is provided with a flow obstruction structure 140 in at least the flow section adjacent to the air intake side 510 of the fan wheel 500. It is understood that a flow-blocking structure 140 is provided in the flow channel 110, and the flow-blocking structure 140 is located at least in the flow section of the flow channel 110 adjacent to the air intake side 510 of the impeller 500. Thus, during the operation of the air conditioner, the impeller 500 rotates and generates negative pressure in the air intake side 510. The condensate flowing in the flow section of the flow channel 110 adjacent to the air intake side 510 will suddenly increase in velocity and tend to deviate from the original flow direction. However, under the action of the flow-blocking structure, the condensate is obstructed when it flows through this point. If the negative pressure generated by the impeller 500 is to carry the condensate out of the flow channel 110, it needs to overcome the gravity of the condensate and the resistance of the flow-blocking structure 140 to the water flow. This prevents the condensate from being easily affected by the negative pressure of the impeller 500, thus ensuring that the condensate flows stably in the flow channel 110. This reduces the probability of condensate overflowing from the flow channel 110 and causing water to soak the components inside the air conditioner or spraying outward with the impeller 500, thereby ensuring the user experience.

[0078] It should be noted that in this embodiment, the flow channel 110 can be positioned in various postures and forms near the suction side 510 of the impeller 500. For example, the flow channel 110 may flow in a vortex shape on the suction side 510 of the impeller 500 and discharge outwards from the center of the vortex; or, the flow may flow in a long strip shape on the suction side 510 of the impeller 500 and then flow to a preset position for discharge or use. As for the impeller 500, it may be used for heat dissipation of the first heat exchanger 200 or to transport the heat generated by the first heat exchanger 200 to the surrounding environment. The impeller 500 can be set in various postures according to the specifications and model of the air conditioner so that the suction side 510 can draw air vertically, horizontally, or at an angle, thereby generating negative pressure on the flow channel 110 of the plate 100.

[0079] In this embodiment, without loss of generality, the main function of the flow-blocking structure 140 is to increase the resistance to the flow of condensate. Under the negative pressure formed on the suction side 510 of the impeller 500, the flow velocity of the condensate on the negative pressure side increases suddenly, and after being guided and superimposed by the flow channel 110, it forms a surge, which may cause the condensate to overflow the flow channel 110 or even be discharged with the impeller 500. The flow-blocking structure 140 can slow down the flow rate of the condensate in the direction of its flow, thereby reducing the probability of the condensate surging and preventing the condensate from overflowing the flow channel 110. The flow-blocking structure 140 can be a bent structure to resist the flow of condensate, or it can be concave and convex at the bottom of the flow channel 110, or it can be multiple plate-like flanges at the top of the flow channel 110 to resist the flow of condensate.

[0080] Furthermore, in this embodiment, please refer to Figures 5 to 7 The flow-blocking structure 140 includes multiple flow-blocking ribs 141, which are spaced apart along a first direction, which is one of the radial directions of the impeller 500. It should be noted that, as... Figure 6As shown, the first direction is the flow direction of condensate in the flow channel 110, and it is also the flow direction on the section of the flow channel 110 adjacent to the suction side 510 of the impeller 500. Furthermore, the first direction is parallel to one of the radial directions of the impeller 500, so that the distribution direction of the multiple wave-damping ribs can be adapted to the direction in which the impeller 500 causes the condensate in the flow channel 110 to gradually surge and churn, ensuring the wave-damping structure's suppression effect on the surging flow of condensate. In this way, the multiple wave-damping ribs 141 can continuously interact with the condensate in the flow direction of the condensate, causing the condensate to form a complex flow path within the flow channel 110, effectively slowing down the flow velocity of the condensate and dispersing the energy accumulated by the condensate flowing within the flow channel 110, preventing the condensate from concentrating in one place, thereby reducing the probability of condensate surging and churning, and preventing condensate from overflowing the flow channel 110. Of course, in other embodiments, the flow-blocking structure 140 may be configured as a plurality of protrusions, which are staggered in the opening direction of the flow channel 110 to obstruct the overflow of condensate water toward the opening at the top of the flow channel 110.

[0081] Furthermore, in this embodiment, please refer to Figure 6 and Figure 7 The flow-blocking ribs 141 are plate-shaped and form an angle with the first direction. It can be understood that, in the direction in which condensate flows along the flow channel 110, the surfaces of the multiple plate-shaped flow-blocking ribs 141 are arranged opposite each other, directly blocking the flow of condensate and preventing it from flowing smoothly towards the suction side 510 of the impeller 500, thereby slowing down the flow velocity of the condensate. Simultaneously, the plate-shaped flow-blocking ribs 141 can disperse the pressure of the condensate over a larger area, preventing water flow from concentrating in one place and reducing the possibility of condensate accumulation and surging. Furthermore, the plate-shaped flow-blocking ribs 141 change the flow direction of the condensate, causing it to form a complex flow path within the flow channel 110, further suppressing the accumulation and surging of condensate. Of course, in other embodiments, the flow-blocking ribs 141 can also be configured as prismatic prisms or cylinders, etc.

[0082] Regarding the distribution of the multiple flow-blocking ribs 141, in one embodiment, please refer to... Figure 6 and Figure 7 At least two adjacent flow-blocking ribs 141 are staggered in the first direction. It can be understood that at least two flow-blocking ribs are distributed perpendicular to the first direction, i.e., the flow direction of the condensate, so that the condensate is continuously blocked and its direction is changed during flow, preventing it from forming a stable flow state, thereby effectively suppressing the accumulation and surging of condensate. Simultaneously, the staggered distribution of the flow-blocking ribs can disperse the pressure of the condensate to different areas, avoiding pressure concentration in one place and reducing the possibility of condensate surging due to pressure concentration. Specifically, in the first direction, multiple flow-blocking ribs are sequentially and alternately staggered; they can be independently set within the flow channel 110, or sequentially connected to opposite side walls of the flow channel 110.

[0083] Regarding the flow path width of condensate in the wave-damping structure, in one embodiment, please refer to... Figure 3 and Figure 4 The sidewall of the flow channel 110 and the flow-blocking rib 141 are opposite each other and have a spacing D, satisfying: 1mm ≤ D ≤ 10mm. The spacing D can be understood as the distance between the flow-blocking rib and the sidewall of the flow channel 110 in the direction perpendicular to the first direction. When the spacing D is between 1mm and 10mm, the flow-blocking rib 141 can effectively block the flow of condensate, preventing it from flowing smoothly forward, thereby slowing down the flow velocity of the condensate and reducing the surging phenomenon caused by the sudden accumulation of condensate due to excessively high flow velocity. At the same time, it also ensures a stable flow state of condensate within the flow channel 110, avoiding local eddies or dead zones within the flow channel 110, thus ensuring the flow efficiency of the condensate. For example, when the condensate flow rate is large, a larger spacing D can ensure that the condensate has sufficient space to flow, avoiding excessive flow resistance due to a small spacing D; when the condensate flow rate is small, a smaller spacing D can better suppress the surging of condensate, ensuring the collection effect of condensate. The spacing D can be 1mm, 3mm, 5mm, 6mm, 8mm, or 10mm, and different wave-damping ribs can have different spacing D values. Of course, in other embodiments, depending on the specifications of different air conditioners, the spacing D can also be greater than 10mm.

[0084] Regarding the dimensions of the wave-damping reinforcement, in one embodiment, please refer to... Figure 6 and Figure 7 The top of the baffle 141 is either lower than or flush with the top opening of the flow channel 110. It should be noted that the top opening of the flow channel 110 faces upwards. Under the action of the suction side 510 of the impeller 500, condensate is drawn up and surges from the top opening of the flow channel 110 towards the suction side 510. When the top of the baffle 141 is lower than or flush with the top opening of the flow channel 110, it effectively prevents condensate from overflowing the flow channel 110 during flow. Even with a large condensate flow rate or high velocity, the baffle 141 prevents condensate from crossing its top and entering the area of ​​the impeller 500, thus avoiding water immersion and spraying problems in the air conditioning components due to condensate overflow. Simultaneously, it also prevents the baffle ribs from extending into the air intake area of ​​the impeller 500, thus avoiding unnecessary disturbance and resistance in the airflow when passing through the baffle ribs 141. This reduces the interference of the baffle ribs 141 on the airflow on the air intake side 510 of the impeller 500, helping to maintain stable wind pressure around the impeller 500 and reducing noise and vibration caused by unstable wind pressure. Of course, in other embodiments, the baffle ribs extending from the top opening of the flow channel 110 can be adapted and arranged according to the airflow direction of the air intake side 510.

[0085] In one embodiment, please refer to Figure 6 and Figure 7 The bottom wall of the flow channel 110 extends downwards at an angle away from the suction side 510 of the impeller 500. This downward angle causes the condensate within the flow channel 110 to flow and accumulate away from the suction side 510 of the impeller 500 under gravity, creating a water level difference within the flow channel 110. The water level on the suction side 510 of the impeller 500 is relatively low, while the water level away from the suction side 510 is higher. This means that the impeller 500 needs to overcome a greater pressure difference generated by the water level difference to draw up the condensate, increasing the difficulty of drawing it up. Simultaneously, the angled bottom wall lengthens the flow path of the condensate drawn up by the impeller 500, increasing the resistance encountered during flow and thus reducing the flow velocity. Furthermore, the angled bottom wall increases the contact area between the condensate and the flow channel 110, increasing the tension between the bottom wall of the flow channel 110 and the condensate, thereby increasing the resistance to the condensate flow and reducing the possibility of condensate turbulence. Of course, in other embodiments, the bottom wall of the flow channel 110 may also be horizontal.

[0086] In one embodiment, please refer to Figures 5 to 7 The air intake side 510 of the impeller 500 and the first heat exchanger 200 are arranged opposite to each other. The flow channel 110 also includes a return water tank 115 that connects to the water tank 112. The return water tank 115 is arranged closer to the air intake side 510 of the impeller 500 than the water tank 112. The flow obstruction structure 140 is arranged in the return water tank 115. Without loss of generality, the air conditioner is equipped with a water-discharging device 400. This device discharging water from the water-discharging tank 112 towards the first heat exchanger 200 to control its temperature and improve heat exchange efficiency. Simultaneously, under the action of the fan wheel 500, the water discharging towards the first heat exchanger 200 moves towards the fan wheel 500 with the airflow. However, under gravity, this water falls into the return water tank 115, where it flows back to the water-discharging tank 112, achieving recycling and preventing water from spilling inside the air conditioner and causing water damage to its components. Thus, the flow-blocking structure 140 of the return water tank 115 slows down the flow rate of the water, preventing it from being sucked up by the fan wheel 500 and thrown towards the air outlet or other parts, thereby preventing water spraying from the air conditioner and improving its safety and comfort. In the case of a large amount of water accumulating in the disc 100, the wave-damping structure on the return water tank 115 can effectively prevent the accumulated water from being sucked out of the flow channel 110 by the impeller 500.

[0087] Furthermore, in this embodiment, regarding the arrangement of the flow-blocking structure 140 on the return water tank 115, please refer to... Figure 4 and Figure 7The flow-blocking structure 140 is disposed on the side wall of the return water tank 115 and / or the side wall of the water jetting tank 112 adjacent to the return water tank 115. It is understood that the flow-blocking structure 140, disposed on the side wall of the return water tank 115 and the water jetting tank 112, forms an integral part with the side wall, increasing the thickness and strength of the side wall, making it more stable under the impact and pressure of condensate, and less prone to deformation or damage. Simultaneously, it can be fixed and installed using the side walls of the return water tank 115 and the water jetting tank 112, making the installation of the flow-blocking structure 140 more secure and reliable, less prone to loosening or displacement, thus ensuring the flow-blocking structure 140's restrictive effect on condensate flow, thereby reducing the probability of condensate surging in the return water tank 115 or the water jetting tank 112. Of course, in other embodiments, the wave-blocking structure can also be independently disposed in the return water tank 115 or the water jetting tank 112, connected only to the bottom wall of the tank.

[0088] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 8 The flow channel 110 also includes a detection tank 117, the bottom of which is higher than the bottom of the water tank 112. The detection tank 117 is used to house the water level detection element 130. When the water level in the water tank 112 rises, water flows into the detection tank 117, triggering the water level detection element 130. When the water level in the detection tank 117 reaches a preset threshold, the water level detection element 130 sends a signal, indicating that the condensate content in the flow channel 110 is too high. The integrated air conditioner will then control the power of the second heat exchanger 300 to reduce condensate production, while also increasing the speed of the fan to accelerate the heat dissipation of the first heat exchanger 200 and promptly discharge the water vapor generated on the first heat exchanger 200, thus reducing the accumulation of condensate. In this way, the amount of condensate accumulated in the flow channel 110 can be controlled, preventing excessive condensate from overflowing from the panel 100, thereby preventing water damage to the components inside the integrated air conditioner, or preventing condensate overflow from polluting and damaging the surrounding environment, ensuring the user experience. Of course, in other embodiments, a water level detection device can also be installed in the drainage area 114. When the water level in the drainage area 114 reaches the preset water level, an early warning is activated or the power of the integrated air conditioner is reduced to reduce condensate production, and the fan is accelerated to promote the discharge of condensate vaporization. If the water level is still at the preset water level after a certain period of time, the user is prompted to drain the water through the drain plug 120.

[0089] Furthermore, in this embodiment, please refer to Figure 2 , Figure 4 and Figure 8The detection tank 117 is located downstream of the water-spraying tank 112 along the flow direction of the channel 110, and the detection tank 117 and the water-spraying tank 112 are connected in parallel to the receiving tank 111. It can be understood that the inlet of the detection tank 117 and the inlet of the water-spraying tank 112 are connected in parallel to the main flow section of the channel 110, so that the detection tank 117 has a relatively independent design, reducing the impact of water flow fluctuations in the water-spraying tank 112 on the water level in the detection tank 117, making the water level change in the detection tank 117 more stable and improving the accuracy of water level detection. At the same time, since the detection tank 117 is located downstream of the water-spraying tank 112, condensate will only flow into the detection tank 117 after the water level in the water-spraying tank 112 rises to a certain level. Therefore, when the water level in the detection tank 117 reaches the preset warning line, it means that the water level in the water-spraying tank 112 is relatively high, and triggering the warning signal at this time is more accurate and reliable. Of course, in other embodiments, the detection groove 117 may also be located upstream of the water jet 112, such as between the drainage area 114 and the water jet 112.

[0090] Specifically, in this embodiment, please refer to Figure 2 and Figure 4 The bottom of the detection tank 117 is H3 higher than the bottom of the water-filling tank 112, and H3 satisfies: 0.05mm ≤ H3 ≤ 10mm. It should be noted that the water-filling tank 112 can promptly consume the condensate in the flow channel 110 to maintain a balanced water level. Once the condensate in the flow channel 110 can flow into the detection tank 117, it indicates that the rate at which the first heat exchanger 200 consumes condensate is slower than the rate at which the second heat exchanger 300 produces condensate. Thus, by limiting H3 to the aforementioned range, the water level change in the detection tank 117 can sensitively reflect the water level in the water-filling tank 112, ensuring that the water level detection element 130 can accurately and promptly detect water level changes, thereby triggering corresponding control actions. Meanwhile, since H3 is within the aforementioned reasonable range, when the water level in the water tank 112 rises slightly, the condensate will not immediately flow into the detection tank 117. Instead, it needs to reach a certain water level before triggering the detection. This avoids false alarms caused by minor water level fluctuations, thereby helping to reduce false alarms and missed alarms caused by water level fluctuations due to water pumping from the water tank 112. H3 can be 0.05mm, 0.1mm, 0.8mm, 1mm, 3mm, 5mm, 6mm, 8mm, or 10mm, etc. Alternatively, in other embodiments, a bottom wall partition can be installed at the inlet of the detection tank 117, with the lowest point of the partition being higher than the bottom of the water tank 112 to meet the H3 value requirement.

[0091] In one embodiment, please refer to Figure 2 and Figure 3A clearance space is formed between the first heat exchanger 200 and the second heat exchanger 300. The plate body 100 is provided with a clearance groove 150 corresponding to the lower part of the clearance space, and the flow channel 110 passes through the lower part of the clearance groove 150. It can be understood that the clearance groove 150 is provided in the lower part of the clearance space between the first heat exchanger 200 and the second heat exchanger 300. The clearance groove 150 and the clearance space can avoid external components, such as the joists of the ceiling (not shown in the figure), or the vertical railings of the side wall of the ambient space. Alternatively, the clearance space and the clearance groove 150 can be used for the installation of an integrated air conditioner, enhancing the installation stability. Here, the clearance groove 150 is used as an example for explanation. The flow channel passes through the lower part of the clearance groove 150 to reduce the interference of the joists on the flow of condensate in the flow channel 110 and improve the compactness of the plate body 100. Regarding the relationship between the clearance space, the clearance channel 150, and the keel, the integrated air conditioner is installed at the top of the indoor space, such as the kitchen ceiling or the toilet ceiling. The first heat exchanger 200 and the second heat exchanger 300 are distributed in parallel, forming a flat, vertically placed rectangular clearance space between them. When installing the integrated air conditioner, the clearance space can avoid interference from the ceiling keel, so that the keel can be adapted to the clearance channel 150 of the panel 100, thereby increasing the installation height of the integrated air conditioner. The flow channel 110 is installed below the clearance channel 150, reducing the interference of the keel on the setting of the flow channel 110 and improving the compactness of the panel 100.

[0092] Specifically, please refer to Figures 2 to 4 Referring to the above description of the drainage area 114, in this embodiment, the drainage area 114 is located on the side of the bypass groove 150 away from the water receiving trough 111 and adjacent to the side of the panel 100. It can be understood that the water receiving trough 111 is connected to the drainage area 114 on the side of the panel 100 via a connecting groove below the bypass groove 150. Thus, the lower end of the bottom of the water receiving trough 111, the connecting groove, and the drainage area 114 are all adjacent to the side of the panel 100, ensuring that the condensate on the water receiving trough 111 flows unidirectionally to the water discharge trough 112, ensuring that the water discharge trough 112 can clearly collect and treat the condensate. Simultaneously, it facilitates the inspection of the drainage area 114 and the connecting groove, reduces obstruction by other components of the integrated air conditioner, and ensures operational convenience when repairing the flow channel 110 of the integrated air conditioner.

[0093] In one embodiment, please refer to Figure 1 and Figure 2The flow channel 110 also includes a connecting channel section (not shown) located below the clearance channel 150, with the bottom wall of the connecting channel section lower than the bottom of the water receiving tank 111. It can be understood that on the side of the clearance channel 150 near the second heat exchanger 300, a significant drop is formed at the connection point between the connecting channel section and the water receiving tank 111. The connection point between the connecting channel section and the drainage area 114 or the water trough 112 exhibits a relatively gentle flow trend, allowing condensate from the water receiving tank 111 to quickly pass through the connecting channel section, reducing the possibility of condensate accumulation within the connecting channel section, thereby preventing excessive water accumulation and seepage below the clearance channel 150. Simultaneously, the downward-sloping bottom wall of the connecting channel section ensures that the bottom of the clearance channel 150 remains at a low position, fully avoiding the joists, thus improving the compatibility of the integrated air conditioner installation with various joists. The bottom of the connecting section corresponding to the clearance channel 150 can be open or have a removable cover, allowing users or maintenance personnel to directly inspect the flow of condensate in the flow channel 110, thus enabling cleaning and maintenance of the flow channel 110 of the integrated air conditioner. This reduces the need for disassembly and reassembly of the integrated air conditioner and improves the convenience of checking the flow of the flow channel 110. Alternatively, the bottom wall of the connecting section corresponding to the clearance channel 150 can be sealed to the connecting section and integrated with the other structures of the connecting section. Of course, in other embodiments, the bottom wall of the connecting section and the bottom of the water receiving tank 111 can be kept uniformly or slightly lower, and a water level difference can be set at the connection between the connecting section and the water receiving tank 112 or the drainage area 114 to reduce the possibility of condensate overflowing below the clearance channel 150.

[0094] In one embodiment, please refer to Figure 1 and Figure 2 A thermal insulation element 151 is adapted to the position of the bypass channel 150 corresponding to the flow channel 110. Generally, the thermal insulation element 151 is configured as a sponge to insulate the connecting channel section, preventing condensation from forming inside the bypass channel 150 due to condensate flowing under it, thus reducing interference with the keel. Alternatively, it can collect condensate in the water trough 112 for use by the first heat exchanger 200. Furthermore, the thermal insulation element 151 has a certain degree of elasticity, which can also buffer potential collisions between the keel and the bypass channel 150, ensuring the installation stability of the integrated air conditioner while reducing its operating noise and interference with the keel. Of course, in other embodiments, a thermal insulation or buffer structure can also be adapted to the entire channel section of the bypass channel 150.

[0095] In this embodiment, please refer to Figure 2 , Figure 5 and Figure 8The clearance slot 150 is configured as a straight slot, and the corresponding clearance space also runs through the casing of the integrated air conditioner along the clearance slot 150. The depth formed by the clearance slot 150 and the clearance space can be 80% to 95% of the vertical dimension of the casing. The first heat exchanger 200 and the second heat exchanger 300 are located on opposite sides of the clearance channel 150 and the clearance space, respectively. The first heat exchanger 200 and the second heat exchanger 300 are separated by the clearance space. That is, the clearance space forms a partition for the integrated air conditioner, so that the component for heat exchange of the indoor unit is located on the side with the second heat exchanger 300, and the component for heat exchange of the outdoor unit is located on the side with the first heat exchanger 200. Correspondingly, the clearance channel 150 also partitions the flow channel 110 of the panel 100. The flow section for receiving condensate is located on one side of the clearance channel 150, such as the water receiving tank 111, while the flow section for using and treating condensate is located on the other side of the clearance channel 150, such as the water filling tank 112, the drainage area 114, the return water tank 115, and the detection tank 117. Here, the partition formed by the clearance channel 150 to the panel 100 also corresponds to the partition of the clearance space to the main unit of the integrated air conditioner. The bottom of the channel 110 corresponding to the channel section on the side of the first heat exchanger has various height differences, so that the channel 110 has clear functional partitions, which facilitates subsequent inspection, maintenance and other operations of the channel 110.

[0096] This utility model also proposes an integrated air conditioner; please refer to [reference needed]. Figure 1 The integrated air conditioner includes a first heat exchanger 200, a second heat exchanger 300, and a panel 100. The specific structure of the panel is as described in the above embodiments.

[0097] The impeller 500 and the first heat exchanger 200 are located on the same side of the clearance space. The impeller is used to discharge the heat generated by the first heat exchanger 200 to the outdoor environment. Corresponding to the above-mentioned partitioning of the clearance space for the components and water channels of the integrated air conditioner, the impeller 500 serves the first heat exchanger 200, and the second heat exchanger 300 is also equipped with a corresponding impeller to exchange heat with the indoor environment.

[0098] In one embodiment, the integrated air conditioner further includes a filter module disposed in the flow channel 110, between the water receiving tank 111 and the water discharge tank 112. It is understood that the filter module, disposed in the flow channel 110, filters the condensate flowing towards the water discharge tank 112, reducing the impurity content of the condensate in the water discharge tank 112, preventing the condensate from corroding the first heat exchanger 200, and reducing the failure rate of the integrated air conditioner. Referring to the above description of the clearance space and clearance channel 150, the filter module is disposed in the clearance channel 150, making full use of the space of the integrated air conditioner, reducing the impact on the placement of other components, and improving the compactness of the integrated air conditioner. Without loss of generality, in the case of an integrated air conditioner used in a kitchen, the filter module contains an oil-absorbing felt to filter out grease from the condensate that forms on the second heat exchanger 300 when cooled, thereby reducing the corrosive contamination of the first heat exchanger 200 by grease, and ensuring the operational stability of the integrated air conditioner.

[0099] For the refrigerant pipes connecting the first heat exchanger 200 and the second heat exchanger 300, please refer to... Figure 1 and Figure 2 The refrigerant pipes connecting the first heat exchanger 200 and the second heat exchanger 300 are laid along the bottom of the clearance groove 150. By making full use of the space at the bottom of the clearance groove 150, the space occupied by the refrigerant pipes in the integrated air conditioner is reduced, making the integrated air conditioner more compact and the layout more reasonable.
