Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a water receiving assembly for a ducted air conditioner and a ducted air conditioner. Background Technology

[0002] Due to global warming, air conditioners are becoming increasingly common, and most people install them in their homes to improve their living environment. Because ducted air conditioners are relatively concealed, they enhance the overall aesthetics of the living room after installation. Unlike wall-mounted units, which are hung on the wall, or floor-standing units, which take up valuable living room space, ducted air conditioners are not installed in the ceiling. However, because they are concealed, repairs can be very difficult if they malfunction, requiring significant work to be done by breaking up the existing ceiling.

[0003] While ducted air conditioners offer advantages such as concealed installation and a good overall room aesthetic after installation, they frequently experience indoor unit leaks. A significant proportion of these leaks are caused by condensate from the indoor unit's drip tray being blown out through the air outlet. Therefore, addressing leaks caused by condensate blowing from the indoor unit of ducted air conditioners is a problem that urgently needs to be solved.

[0004] Currently, the air conditioning industry employs several technical methods to prevent condensation from blowing out of the indoor unit. For example, Chinese patent CN221250491U discloses a parking air conditioner that uses a pressure equalization pipe to address the issue of condensation blowing out of the indoor unit due to negative pressure. However, this patent's U-shaped pressure equalization pipe connects the air inlet and outlet of the indoor unit's evaporator assembly, reducing the negative pressure difference and minimizing the problem of condensation overflowing from the drip tray and causing blowing out. Since the evaporator is connected at both ends by the pressure equalization pipe, it affects the outlet air temperature. Furthermore, the pressure equalization pipe's diameter is only 4 cm, resulting in a negligible effect on actual pressure equalization. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a water receiving component and a duct air conditioner, which aims to solve the problem of water leakage caused by condensate blowing out of the indoor unit of the duct air conditioner.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: On one hand, this utility model provides a water receiving assembly for a ducted air conditioner, including a water receiving tray and a baffle plate disposed in the air duct. The water receiving tray has a high-pressure zone on the high-pressure side of the air duct and a low-pressure zone on the low-pressure side of the air duct, with the low-pressure zone close to the air outlet of the ducted air conditioner. The baffle plate is disposed between the high-pressure zone and the low-pressure zone, and the baffle plate has a clearance hole that connects the high-pressure zone and the low-pressure zone. The water receiving tray has a drain hole and also includes a water guide pipe. The inlet end of the water guide pipe is connected to the clearance hole, and the outlet end of the water guide pipe is connected to the drain hole.

[0007] Furthermore, a baffle is provided extending along the length of the water guide pipe, which divides the inner cavity of the water guide pipe into a first flow channel and a second flow channel. A flow-blocking plate perpendicular to its flow direction is provided in the second flow channel, and a water inlet communicating with the high-pressure zone is also provided in the second flow channel. The flow-blocking plate is located upstream of the water inlet along the flow direction of the second flow channel.

[0008] Furthermore, the inlet end of the water guide pipe passes through the relief hole, and the outer surface of the inlet end of the water guide pipe is in close contact with the wall of the relief hole.

[0009] Furthermore, the outlet end of the water guide pipe passes through the drain hole, and the outer surface of the outlet end of the water guide pipe is in close contact with the hole wall of the drain hole.

[0010] Furthermore, the water guide pipe is a straight-through circular pipe structure.

[0011] Furthermore, the water guide pipe includes a straight pipe body section, and the baffle is provided inside the straight pipe body section.

[0012] Furthermore, the water guide pipe also includes a straight pipe extension section, the diameter of which is larger than the diameter of the main straight pipe section, and the connection between the straight pipe extension section and the main straight pipe section is provided with an outer step portion.

[0013] Furthermore, the straight pipe additional section extends along the length direction of the straight pipe additional section and is provided with a straight pipe extension section, which is located in the inner cavity of the straight pipe additional section.

[0014] Furthermore, the length of the straight pipe extension is greater than 10 mm.

[0015] On the other hand, this utility model also provides a duct air conditioner, including the above-mentioned duct air conditioner water receiving component.

[0016] The beneficial effects of this utility model compared with the prior art are as follows: The water receiving component of the duct air conditioner includes a water receiving tray and a baffle plate disposed within the air duct. The water receiving tray has a high-pressure zone on the high-pressure side and a low-pressure zone on the low-pressure side within the air duct, with the low-pressure zone close to the air outlet of the duct air conditioner. The baffle plate is disposed between the high-pressure zone and the low-pressure zone, and has a clearance hole connecting the high-pressure zone and the low-pressure zone. The water receiving tray has a drain hole and also includes a water guide pipe. The inlet end of the water guide pipe is connected to the clearance hole, and the outlet end of the water guide pipe is connected to the drain hole. This utility model, through the water guide pipe, prevents high-pressure air on the high-pressure side of the air duct from blowing into the low-pressure zone through the clearance hole, thus avoiding the problem of high-pressure air on the high-pressure side blowing condensate in the water receiving tray towards the air outlet and causing leakage.

[0027] like Figures 1 to 8 As shown, this utility model embodiment provides a duct air conditioner, including a duct component 1, an evaporator component 2, and a duct air conditioner water receiving assembly. The duct air conditioner water receiving assembly includes a water receiving tray 3 and a baffle plate 4 disposed in the duct. The water receiving tray 3 has a high-pressure zone 200 located on the high-pressure side of the duct and a low-pressure zone 300 located on the low-pressure side of the duct. The low-pressure zone 300 is close to the air outlet of the duct air conditioner. The baffle plate 4 is disposed between the high-pressure zone 200 and the low-pressure zone 300. The baffle plate 4 has a clearance hole 41 that connects the high-pressure zone 200 and the low-pressure zone 300. The water receiving tray 3 has a drain hole 31 and also includes a water guide pipe 5. The water inlet end of the water guide pipe 5 is connected to the clearance hole 41, and the water outlet end of the water guide pipe 5 is connected to the drain hole 31.

[0028] The duct component 1 provides a channel for air circulation inside the duct unit. Due to the air delivery action of the fan, there is a pressure distribution difference inside it. The area near the fan outlet is the high-pressure side of the duct, and the area near the final air outlet of the duct unit is the low-pressure side of the duct. The evaporator component 2 is located inside the duct component 1 and is used to exchange heat with the air in the duct. During the heat exchange process, condensate 100 will be generated. This condensate 100 needs to be discharged in time through the duct unit's water collection component to avoid water leakage caused by accumulation.

[0029] The drip tray 3 has a trough-shaped structure and is horizontally positioned below the evaporator component 2. It is used to collect the condensate 100 generated by the evaporator component 2. According to the pressure distribution in the air duct, the drip tray 3 is divided into a high-pressure zone 200 located on the high-pressure side of the air duct and a low-pressure zone 300 located on the low-pressure side of the air duct. The low-pressure zone 300 is close to the air outlet of the duct unit, so that the drip tray 3 can fully cover the area where the condensate 100 is generated below the evaporator component 2, ensuring that the condensate 100 can fall into the drip tray 3.

[0030] The baffle plate 4 is a plate-shaped structure, vertically installed between the high-pressure zone 200 and the low-pressure zone 300 of the water receiving tray 3. Its function is to initially separate the airflow on the high-pressure side and the low-pressure side in the air duct, reducing the direct impact of the high-pressure airflow on the condensate 100 in the low-pressure zone 300. In order to achieve unified discharge of the condensate 100 in the high-pressure zone 200 and the low-pressure zone 300 of the water receiving tray 3, the baffle plate 4 is provided with a clearance hole 41 that connects the high-pressure zone 200 and the low-pressure zone 300. The axis of the clearance hole 41 is set horizontally, and its diameter is matched with the outer diameter of the water guide pipe 5 to ensure the sealing after the two are connected.

[0031] A drain hole 31 is provided on the side of the water receiving tray 3 near the high-pressure zone 200 to discharge the condensate 100 collected in the water receiving tray 3 to the outside of the duct unit; one end of the water guide pipe 5 is the water inlet end and the other end is the water outlet end. The water inlet end of the water guide pipe 5 is connected to the clearance hole 41 on the wind baffle 4, and the water outlet end of the water guide pipe 5 is connected to the drain hole 31 of the water receiving tray 3, forming a condensate 100 discharge channel from the high-pressure zone 200 and low-pressure zone 300 of the water receiving tray 3 to the outside of the duct unit.

[0032] During assembly, the inlet end of the water guide pipe 5 is tightly connected to the clearance hole 41, which effectively prevents high-pressure air from the high-pressure side of the duct from entering the low-pressure zone 300 through the gap between the two. The outlet end of the water guide pipe 5 is also tightly connected to the drain hole 31, ensuring that all the condensate 100 in the water receiving tray 3 can be discharged through the water guide pipe 5 without leakage. When the duct unit is running, the condensate 100 generated by the evaporator component 2 falls into the high-pressure zone 200 and the low-pressure zone 300 of the water receiving tray 3 respectively. Under the action of high pressure in the duct, the condensate 100 in the high-pressure zone 200 enters the interior of the water guide pipe 5 through the inlet end of the water guide pipe 5, while the condensate 100 in the low-pressure zone 300 flows directly into the water guide pipe 5. Finally, both are discharged to the outside of the duct unit through the outlet end of the water guide pipe 5 and the drain hole 31 of the water receiving tray 3.

[0033] By configuring the water guide pipe 5 and ensuring its close cooperation with the clearance hole 41 and drain hole 31, high-pressure air on the high-pressure side of the duct cannot be blown into the low-pressure area 300 through the clearance hole 41. This avoids the reverse force exerted by high-pressure air blown out through the clearance hole 41 on the condensate 100 generated by the evaporator in traditional ducted air conditioners, which would cause poor drainage of the drip tray 3. This also prevents leakage problems caused by the condensate 100 continuously increasing in the drip tray 3 after prolonged operation, leading to a rise in the water level and eventually being blown towards the air outlet. This reduces quality issues caused by leakage and improves the user experience. Simultaneously, the water guide pipe 5 forms a unified condensate 100 drainage channel, allowing condensate 100 from both the high-pressure area 200 and the low-pressure area 300 of the drip tray 3 to drain smoothly. This prevents poor drainage and condensate 100 accumulation in the drip tray 3 due to pressure differences within the duct, ensuring long-term stable operation of the ducted air conditioner.

[0034] In one embodiment, such as Figures 6 to 8 As shown, a baffle 53 extends along the length of the water pipe 5, dividing the inner cavity of the water pipe 5 into a first flow channel 513 and a second flow channel 512. A flow baffle 54 perpendicular to the flow direction is provided in the second flow channel 512. A water inlet 511 communicating with the high-pressure zone 200 is also provided in the second flow channel 512. The flow baffle 54 is located upstream of the water inlet 511 along the flow direction of the second flow channel 512.

[0035] The water guide pipe 5 is a tubular structure with a preset length. Its two ends serve as the water inlet end connected to the relief hole 41 of the wind baffle 4 and the water outlet end connected to the drain hole 31 of the water receiving tray 3, respectively, so as to realize the conduction of condensate 100 from the water receiving tray 3 to the outside of the air duct unit. In the inner cavity of the water guide pipe 5, a baffle 53 is provided extending along the length direction of the water guide pipe 5. The extension direction of the baffle 53 is consistent with the axial direction of the water guide pipe 5, and the edge of the baffle 53 is tightly connected to the inner wall of the water guide pipe 5. Specifically, it can be manufactured by integral molding process or fixed by welding, bonding or other methods to ensure that there is no gap between the baffle 53 and the inner wall of the water guide pipe 5, thereby completely dividing the inner cavity of the water guide pipe 5 into two independent flow channels 513 and 512. One end of the first flow channel 513 corresponds to the low-pressure zone 300 of the water collection tray 3 (the side near the air outlet of the duct unit), and is used to collect and discharge the condensate 100 collected in the low-pressure zone 300 of the water collection tray 3. Since the air outlet of the duct unit has a certain static pressure, which is greater than the atmospheric pressure at the water outlet of the water guide pipe 5, the condensate 100 at the air outlet of the water collection tray 3 can be directly discharged to the outside of the duct unit through the first flow channel 513 of the water guide pipe 5. One end of the second flow channel 512 corresponds to the high-pressure zone 200 of the water collection tray 3 (the area corresponding to the high-pressure side inside the duct), and is specifically used to collect and discharge the condensate 100 collected in the high-pressure zone 200 of the water collection tray 3.

[0036] Inside the second flow channel 512, a baffle plate 54 is also provided. The extension direction of the baffle plate 54 is perpendicular to the flow direction of the condensate 100 in the second flow channel 512, that is, the baffle plate 54 is arranged laterally in the second flow channel 512. The edge of the baffle plate 54 is also tightly connected to the inner wall of the second flow channel 512 (including the side of the partition plate 53 and the inner wall of the water guide pipe 5), forming a lateral obstruction of the inner cavity of the second flow channel 512. At the same time, at least one water inlet hole 511 is provided on the pipe wall of the second flow channel 512. The water inlet hole 511 penetrates the pipe wall of the water guide pipe 5, and its inner side communicates with the inner cavity of the second flow channel 512, while its outer side communicates with the high-pressure area 200 of the water receiving tray 3, so that the condensate 100 in the high-pressure area 200 of the water receiving tray 3 can flow into the second flow channel 512 through the water inlet hole 511. It should be noted that the water inlet 511 must be connected only to the high-pressure zone 200 and not to the low-pressure zone 300.

[0037] like Figure 8 As shown, Figure 8 The arrows in the diagram indicate the flow direction of the condensate 100. From the perspective of the flow direction of the condensate 100 in the second flow channel 512, the baffle plate 54 is positioned upstream of the water inlet 511. That is, the baffle plate 54 can separate the high-pressure side and the low-pressure side in the air duct, thus preventing the condensate 100 in the high-pressure zone 200 of the water tray 3 from reaching the low-pressure zone 300.

[0038] The partition 53 divides the inner cavity of the water pipe 5 into an independent first flow channel 513 and a second flow channel 512, thus completely separating the discharge paths of the condensate 100 from the high-pressure zone 200 and the low-pressure zone 300 of the water receiving tray 3, preventing the airflow in the high-pressure zone 200 from entering the low-pressure zone 300 along with the condensate 100. In one embodiment, the inlet end of the water guide pipe 5 passes through the relief hole 41, and the outer surface of the inlet end of the water guide pipe 5 is tightly fitted with the wall of the relief hole 41. The outlet end of the water guide pipe 5 passes through the drain hole 31, and the outer surface of the outlet end of the water guide pipe 5 is tightly fitted with the wall of the drain hole 31.

[0039] In this embodiment, the baffle plate 4 is vertically positioned between the high-pressure zone 200 and the low-pressure zone 300 of the water receiving tray 3. The clearance hole 41 on the baffle plate 4 is a circular through-hole penetrating the plate body. The diameter of the clearance hole 41 matches the outer diameter of the water inlet end of the water guide pipe 5. During assembly, the water inlet end of the water guide pipe 5 is axially inserted into the clearance hole 41, ensuring that the outer surface of the water inlet end is completely flush with the wall of the clearance hole 41, forming a tight fit. Specifically, this tight fit can be achieved by controlling the dimensional tolerance between the outer diameter of the water inlet end of the water guide pipe 5 and the diameter of the clearance hole 41, ensuring no significant gap after assembly. A transition fit or a small interference fit can be used, which facilitates assembly and prevents high-pressure airflow from the high-pressure side of the duct from entering the low-pressure zone 300 through the gap, thereby preventing the high-pressure airflow from impacting the condensate 100 in the low-pressure zone 300 and causing water blowing problems. In order to minimize the gap between the water pipe 5 and the relief hole 41 of the wind deflector 4, the outer diameter of the water pipe 5 is only 1mm smaller than the inner diameter of the right relief hole 41.

[0040] The drain hole 31 of the water tray 3 is a circular through hole, the diameter of which matches the outer diameter of the water outlet end of the water guide pipe 5. During assembly, the water outlet end of the water guide pipe 5 is inserted axially into the drain hole 31, so that the outer surface of the water outlet end is tightly fitted with the hole wall of the drain hole 31. Similar to the water inlet end, this fit is also made tight by controlling the dimensional tolerance. The appropriate fitting precision can be selected according to the material of the water tray 3 (such as plastic or metal). For example, when the water tray 3 is made of plastic, a slight interference fit can be used. The slight deformation of the plastic makes the outer surface of the water outlet end in close contact with the hole wall of the drain hole 31, ensuring that the condensate 100 collected in the water tray 3 can only be discharged through the inner cavity of the water guide pipe 5, and will not leak from the gap between the two into other parts inside the air duct unit, avoiding equipment failure or indoor dripping problems caused by the leakage of condensate 100.

[0041] In the actual assembly process, the inlet end of the water guide pipe 5 can be inserted into the relief hole 41 of the baffle plate 4 and adjusted to the preset position to ensure that the axis of the water guide pipe 5 coincides with the axis of the relief hole 41, achieving uniform fit; then, the outlet end of the water guide pipe 5 is aligned with the drain hole 31 of the water receiving tray 3 and inserted to complete the overall assembly. After assembly, the airtightness test can be used to verify the sealing performance of the fit between the inlet end and the relief hole 41 (e.g., introducing gas at a preset pressure into the high-pressure side of the air duct and checking for gas leakage in the low-pressure area 300) to ensure that the fit structure meets the usage requirements.

[0042] The tight fit between the inlet end of the water guide pipe 5 and the clearance hole 41 completely seals the gap channel through which the high-pressure side airflow flows to the low-pressure side within the duct, preventing the high-pressure airflow from impacting the condensate 100 in the low-pressure zone 300. This solves the problem of water leakage caused by airflow movement in traditional ducted air conditioners at its source. Simultaneously, the tight fit between the outlet end of the water guide pipe 5 and the drain hole 31 forms a sealed channel for the discharge of condensate 100. This ensures that all the condensate 100 collected in the drip tray 3 can be discharged to the outside of the ducted air conditioner through the water guide pipe 5 without leakage. This prevents damage to internal components (such as the motor and circuit board) caused by condensate 100 soaking the ducted air conditioner, extending its service life.

[0043] In one embodiment, such as Figure 7 and Figure 8 As shown, the water guide pipe 5 is a straight-through circular pipe structure. The water guide pipe 5 includes a straight main pipe section 51, within which a baffle 53 is provided. The water guide pipe 5 also includes a straight additional pipe section 52, the diameter of which is larger than the diameter of the straight main pipe section 51. An external step is provided at the connection between the straight additional pipe section 52 and the straight main pipe section 51. A straight extension section 55 extends along the length of the straight additional pipe section 52 and is located within the inner cavity of the straight additional pipe section 52.

[0044] The water guide pipe 5 is a straight-through circular pipe structure, that is, the main body of the water guide pipe 5 extends in a straight line and the cross-section of the pipe is circular. This structure is not only easy to process and manufacture, but also ensures that the condensate 100 has less resistance when flowing in the pipe, avoiding water flow blockage caused by pipe bending or irregular cross-section.

[0045] Specifically, the water pipe 5 includes three parts: the main straight pipe section 51, the additional straight pipe section 52, and the straight pipe extension section 55. Each part is integrally molded (e.g., by injection molding or metal cutting) to ensure the sealing and structural strength of the overall structure and to avoid water leakage or air leakage caused by gaps in the segmented assembly.

[0046] The two ends of the straight pipe main body section 51 are respectively connected to the baffle plate 4 clearance hole 41 and the water receiving tray 3 drain hole 31 in the water receiving assembly of the air duct machine, providing the main flow channel for the condensate 100. In the inner cavity of the straight pipe main body section 51, a baffle plate 53 is provided extending along the length of the straight pipe main body section 51. The extension direction of the baffle plate 53 is consistent with the axial direction of the straight pipe main body section 51, and the two sides of the baffle plate 53 are tightly connected to the inner wall of the straight pipe main body section 51 (without obvious gaps), thereby completely dividing the inner cavity of the straight pipe main body section 51 into two independent flow channels.

[0047] A straight pipe extension section 52 is located at the end of the straight pipe main section 51 near the drain hole 31 of the water receiving pan 3. Its cross-section is also circular, and the diameter of the extension section 52 is larger than that of the straight pipe main section 51, creating an annular outer step at their junction. A straight pipe extension section 55 extends along the length of the extension section 52 and is entirely within the inner cavity of the extension section 52. Its cross-section is also circular, and its extension direction is consistent with the axial direction of the extension section 52. One end of the extension section 55 connects to the end face of the straight pipe main section 51 (the end near the extension section 52), and the other end extends towards the open end of the extension section 52 (not exceeding the end of the extension section 52), forming an "inner pipe" structure nested within the extension section 52. This extension section 55 prevents condensate 100 from flowing back into the water receiving pan 3. To further enhance the effect of preventing condensate 100 from flowing back, the length of the extension section 55 is greater than 10 mm. In addition, when the condensate 100 flows out from the two flow channels (i.e. the first flow channel 513 and the second flow channel 512) of the main body section 51 of the straight pipe, it will first enter the annular gap between the straight pipe extension section 55 and the straight pipe auxiliary section 52, and then be discharged to the outside of the air duct machine through the open end of the straight pipe auxiliary section 52. This double-layer pipe structure can further slow down the water flow speed and prevent the condensate 100 from splashing due to excessive flow speed when it is discharged. At the same time, it can also enhance the structural strength of the end of the water guide pipe 5 and prevent the end from deforming during long-term use.

[0048] It should be noted that the straight pipe extension section 52 can also serve as a connection structure with other components to facilitate the discharge of condensate 100.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
