Description

Technical Field

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

[0002] Ducted air conditioners in related technologies typically include a casing, a heat exchanger, and a fan assembly. The fan assembly drives air to enter the casing from the air inlet and, after exchanging heat with the heat exchanger, flows into the room from the air outlet.

[0003] Furthermore, the ducted air conditioner in the relevant technology is also equipped with a water receiving tray, which is located inside the casing and below the heat exchanger. A flexible sealing element, such as a sponge, is installed between the water receiving tray and the base plate to fill the gap between the water receiving tray and the base plate, thereby preventing the low-temperature air after heat exchange by the heat exchanger from entering the gap between the water receiving tray and the base plate, thus preventing condensation from occurring between the water receiving tray and the base plate.

[0004] However, since the seal is a large-area seal between the seal and the water tray and the base plate, the sealing effect between the seal and the water tray and the base plate is poor. Gaps are easily generated between the seal and the water tray and the base plate. The low-temperature air formed after heat exchange in the heat exchanger can easily enter between the water tray and the base plate, which will cause condensation to form between the water tray and the base plate. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide a ductwork machine that utilizes ribs to compress a first flexible sealing element, thereby improving the sealing performance between the water tray and / or the base plate and the first flexible sealing element. This effectively prevents low-temperature air from entering between the water tray and the base plate, thus avoiding the formation of condensate between them.

[0006] To achieve the above objectives, an air duct unit is proposed according to an embodiment of the present invention. The air duct unit includes: a housing, wherein an air inlet and an air outlet are formed on opposite sides of the housing, and the housing has a base plate; a heat exchanger, wherein the heat exchanger is disposed inside the housing and adjacent to the air outlet; and a fan assembly, wherein the fan assembly is disposed inside the housing and adjacent to the air inlet, the fan assembly driving air to enter the housing from the air inlet, and the air, after exchanging heat with the heat exchanger, passes through the air outlet. Entering the room; the duct unit further includes: a water receiving tray, which is disposed inside the housing and located below the heat exchanger; a first flexible seal, which is fitted between the water receiving tray and the base plate to fill the gap between the water receiving tray and the base plate; wherein, at least one of the water receiving tray and the base plate is provided with a rib, the rib extending along the width direction of the duct unit, and the rib protruding from the side of the base plate and / or the water receiving tray facing the first flexible seal.

[0007] The above technical solution has the following advantages or beneficial effects: by setting a rib in at least one of the base plate and the water receiving tray, the contact area between the rib and the first flexible seal can be smaller, and the pressure of the rib on the first flexible seal can be greater under the same force. In this way, the rib can be used to press the first flexible seal tightly, thereby improving the sealing effect between the water receiving tray and / or the base plate and the first flexible seal at the rib, preventing low temperature air from entering between the base plate and the water receiving tray, and preventing low temperature air and normal temperature air from merging between the water receiving tray and the base plate to produce condensation.

[0008] According to some embodiments of the present invention, there are multiple ribs, and the multiple ribs are arranged at intervals along the width direction of the ribs.

[0009] The above technical solution has the following advantages or beneficial effects: by setting multiple ribs, the multiple ribs can be used together to squeeze and seal the first flexible seal. The multiple ribs can form a multi-layer seal, which further improves the sealing effect between the ribs and the first flexible seal. This more effectively improves the sealing effect between the water receiving tray and the base plate. Low-temperature air is less likely to enter between the water receiving tray and the base plate, and condensation is more effectively avoided between the water receiving tray and the base plate.

[0010] According to some embodiments of the present invention, the rib includes a first inclined surface and a second inclined surface arranged along the width direction of the rib, and the adjacent ends of the first inclined surface and the second inclined surface protrude toward the first flexible seal and are connected to each other.

[0011] The above technical solution has the following advantages or beneficial effects: the contact area between the first flexible seal and the rib is smaller, the rib can more reliably press the first flexible seal to avoid gaps between the rib and the first flexible seal, further improving the sealing between the base plate and the water tray, and making it less likely for low-temperature air to enter between the base plate and the water tray, thereby avoiding the generation of condensate between the water tray and the base plate.

[0012] According to some embodiments of the present invention, the base plate includes: a main body portion supported below the water receiving tray; a bent portion connected to the front end of the main body portion and bent upward relative to the main body portion, the front side of the water receiving tray abutting against the bent portion; wherein, both the main body portion and the bent portion are provided with at least one of the protruding ribs.

[0013] The above technical solution has the following advantages or beneficial effects: both the main body and the bending part are provided with ribs, which can improve the sealing effect of the main body and the first flexible seal, as well as the sealing effect of the bending part and the first flexible seal, so as to ensure that the overall sealing performance of the base plate and the first flexible seal is good. The first flexible seal can better fill the gap between the base plate and the water receiving tray, thereby improving the sealing performance between the base plate and the water receiving tray.

[0014] According to some embodiments of the present invention, a portion of the first flexible seal is located between the main body and the bottom of the water receiving tray, and a portion of the first flexible seal is located between the bent portion and the front side of the water receiving tray.

[0015] The above technical solution has the following advantages or beneficial effects: by using multiple ribs to press different positions of the first flexible seal, the first flexible seal can better fit between the main body and the water receiving tray, as well as between the bent part and the water receiving tray. This arrangement can improve the sealing performance between the main body and the water receiving tray, and also improve the sealing performance between the bent part and the water receiving tray, thereby better preventing low-temperature air from entering between the water receiving tray and the base plate.

[0016] According to some embodiments of the present invention, the lower edge of the front side of the water receiving tray is constructed with an arc-shaped transition surface, and the first flexible seal is attached to the arc-shaped transition surface.

[0017] The above technical solution has the following advantages or beneficial effects: by constructing an arc-shaped transition surface on the lower edge of the front side of the water receiving pan, the middle part of the first flexible seal can better fit into the arc-shaped transition surface, and the first flexible seal can be used to better fill and seal the gap between the water receiving pan and the base plate. Low-temperature air is less likely to flow into the gap between the water receiving pan and the base plate, and the problem of condensation between the water receiving pan and the base plate is more effectively avoided.

[0018] According to some embodiments of the present invention, the duct air conditioner further includes: a fan partition, the fan partition being disposed within the housing and located between the heat exchanger and the fan assembly, the fan assembly being connected to the fan partition, and the rear side of the water receiving tray abutting against the fan partition; wherein, at least one of the fan partition and the water receiving tray is provided with a boss, the boss extending along the width direction of the duct air conditioner, and the boss protruding from the side of the fan partition facing the water receiving tray, and / or the boss protruding from the side of the water receiving tray facing the fan partition.

[0019] The above technical solution has the following advantages or beneficial effects: By placing the fan baffle between the heat exchanger and the fan assembly, this arrangement can isolate the heat exchanger and the fan assembly, avoiding mutual interference. By abutting the rear side of the water receiving tray against the fan baffle, the fan baffle can limit the water receiving tray in the front-rear direction of the duct machine. The rear side of the water receiving tray and the fan baffle can be sealed to prevent air from entering the bottom of the water receiving tray and the base plate through the gap between the water receiving tray and the fan baffle. The boss can be used to improve the structural strength of the fan baffle itself, so as to reliably support and fix the fan assembly through the fan baffle. On the other hand, the boss can be used to improve the sealing between the fan baffle and the water receiving tray, preventing air from entering the bottom of the water receiving tray and the base plate through the gap between the water receiving tray and the fan baffle.

[0020] According to some embodiments of the present invention, the duct machine further includes: a second flexible seal, which is attached to the rear side of the water receiving tray and the fan partition to fill the gap between the water receiving tray and the fan partition.

[0021] The above technical solution has the following advantages or beneficial effects: by setting a boss to compress the second flexible seal, the contact area between the boss and the second flexible seal can be smaller, and the pressure of the water receiving tray and / or fan baffle on the second flexible seal at the boss can be larger. In this way, the boss can be used to press the second flexible seal, thereby improving the sealing effect between the water receiving tray and / or fan baffle at the boss and the second flexible seal. This can more effectively prevent room temperature air from entering between the water receiving tray and the bottom plate through the gap between the rear side of the water receiving tray and the fan baffle, thereby preventing room temperature air and low temperature air from merging and producing condensation between the water receiving tray and the bottom plate.

[0022] According to some embodiments of the present invention, the width of the boss is greater than the width of the rib.

[0023] The above technical solution has the following advantages or beneficial effects: by setting the width of the boss to be wider, the structural strength of the fan baffle can be greatly improved by the boss, and the fan baffle is not easy to deform. By setting the width of the rib to be smaller, the contact area between the rib and the first flexible seal can be smaller, so that the rib can press the first flexible seal tightly, thereby improving the sealing effect between the front side of the water receiving tray and the bottom plate, and more effectively preventing low temperature air from entering between the water receiving tray and the bottom plate.

[0024] According to an embodiment of this utility model, a ducted air conditioner is provided, comprising: a housing, wherein an air inlet and an air outlet are formed on opposite sides of the housing, and the housing has a base plate; a heat exchanger, wherein the heat exchanger is disposed inside the housing and adjacent to the air outlet; a fan assembly, wherein the fan assembly is disposed inside the housing and adjacent to the air inlet, the fan assembly driving air to enter the housing from the air inlet, and the air, after exchanging heat with the heat exchanger, enters the room through the air outlet; a fan partition, wherein the fan partition is disposed inside the housing and located between the heat exchanger and the fan assembly, and the fan assembly is connected to the fan partition; the ducted air conditioner further comprises: a dredging tray, wherein the dredging tray is disposed in the housing. The system comprises: an inner part located below the heat exchanger; a first flexible seal disposed between the water receiving tray and the base plate to fill the gap between the water receiving tray and the base plate; a second flexible seal disposed between the rear side of the water receiving tray and the fan baffle to fill the gap between the water receiving tray and the fan baffle; wherein the base plate is provided with a rib extending along the width direction of the duct machine and protruding from the side of the base plate facing the first flexible seal; and the fan baffle is provided with a boss extending along the width direction of the duct machine and protruding from the side of the fan baffle facing the second flexible seal.

[0025] The above technical solution has the following advantages or beneficial effects: The contact area between the rib and the first flexible seal can be smaller, and under the same force, the pressure of the rib on the first flexible seal can be greater. This allows the rib to press the first flexible seal tightly, improving the sealing effect between the base plate and the first flexible seal at the rib, preventing gaps between the base plate and the first flexible seal, and making it less likely for low-temperature air cooled by the heat exchanger to enter between the base plate and the water tray. The contact area between the boss and the second flexible seal can also be smaller, and the pressure of the fan baffle on the second flexible seal at the boss can be greater. This allows the boss to press the second flexible seal tightly, further improving the sealing effect between the fan baffle and the second flexible seal at the boss, preventing gaps between the fan baffle and the second flexible seal, and thus more effectively preventing room temperature air from entering between the water tray and the base plate through the gap between the rear side of the water tray and the fan baffle. This also prevents room temperature air and low-temperature air from merging and forming condensate between the water tray and the base plate.

[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0047] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0048] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0049] The following description, with reference to the accompanying drawings, describes a ductwork unit 1 according to an embodiment of the present invention.

[0050] like Figures 1-10 As shown in the attached figure, the front-back direction is the front-back direction of the duct unit 1, and the up-down direction is the up-down direction of the duct unit 1.

[0051] According to an embodiment of the present utility model, the duct air conditioner 1 may include a housing 100, on which an air inlet 110 and an air outlet 120 are formed on opposite sides, and the housing 100 has a base plate 130, so that air can flow into the duct air conditioner 1 through the air inlet 110 and flow into the room through the air outlet 120.

[0052] The ducted air conditioner 1 may include a heat exchanger 200, which is located inside the casing 100 and adjacent to the air outlet 120. After air exchanges heat with the heat exchanger 200 to form a heat exchange airflow, it can flow into the room through the air outlet 120 to achieve cooling or heating of the room. For example, when the heat exchanger 200 acts as an evaporator, ambient temperature air flows through the heat exchanger 200 and its temperature decreases to form low-temperature air. This low-temperature air then flows into the room through the air outlet, thereby achieving cooling of the room.

[0053] The ducted air conditioner 1 may include a fan assembly 300, which is located inside the casing 100 and adjacent to the air inlet 110. The fan assembly 300 drives air to enter the casing 100 from the air inlet 110, and after exchanging heat with the heat exchanger 200, the air enters the room through the air outlet 120. This arrangement allows the fan assembly 300 to draw outside air into the casing 100, thus guiding the airflow and improving the air volume through the ducted air conditioner 1, thereby increasing the heat exchange efficiency between the air and the heat exchanger 200.

[0054] The ducted air conditioner 1 may also include a drip tray 400, which is located inside the housing 100 and below the heat exchanger 200. Understandably, when the ducted air conditioner 1 is cooling, the heat exchanger 200 acts as an evaporator. Since the surface temperature of the evaporator is lower than the air dew point temperature, water vapor in the air condenses into water droplets. The drip tray 400 collects these dripping condensates to prevent leakage and contamination of the walls or other components inside the ducted air conditioner 1.

[0055] The duct unit 1 may also include a first flexible seal 500, which is fitted between the drip tray 400 and the base plate 130 to fill the gap between them. For example, the first flexible seal 500 may be a sponge, but is not limited thereto.

[0056] By using the first flexible seal 500 to fill the gap between the water receiving tray 400 and the base plate 130, the gap between the water receiving tray 400 and the base plate 130 can be prevented from being too large, thereby improving the sealing performance between the water receiving tray 400 and the base plate 130, preventing low-temperature air from entering between the water receiving tray 400 and the base plate 130, and thus preventing condensation from forming between the water receiving tray 400 and the base plate 130.

[0057] At least one of the water receiving tray 400 and the base plate 130 is provided with a rib 131, which extends along the width direction of the duct machine 1 and protrudes from the side of the base plate 130 and / or the water receiving tray 400 facing the first flexible seal 500.

[0058] The fact that at least one of the water receiving tray 400 and the base plate 130 is provided with a raised rib 131 means that the raised rib 131 can be provided on the base plate 130; or, the raised rib 131 can be provided on the water receiving tray 400; or, the raised rib 131 can be provided on both the water receiving tray 400 and the base plate 130.

[0059] According to the embodiment of the present invention, the duct air conditioner 1 has a raised rib 131 provided in at least one of the base plate 130 and the water receiving tray 400. The contact area between the raised rib 131 and the first flexible seal 500 can be smaller, and the pressure of the raised rib 131 on the first flexible seal 500 can be greater under the same force. In this way, the raised rib 131 can be used to press the first flexible seal 500, thereby improving the sealing effect between the water receiving tray 400 and / or the base plate 130 and the first flexible seal 500 at the raised rib 131, avoiding the formation of gaps between the water receiving tray 400 and / or the base plate 130 and the first flexible seal 500. The low-temperature air cooled by the heat exchanger is less likely to enter between the base plate 130 and the water receiving tray 400, thereby preventing the low-temperature air and the normal temperature air from merging between the water receiving tray 400 and the base plate 130 and producing condensate.

[0060] Thus, according to the embodiment of the present invention, the duct machine 1 uses the protruding rib 131 to compress the first flexible sealing member 500, which can improve the sealing performance between the water receiving tray 400 and / or the base plate 130 and the first flexible sealing member 500, thereby effectively preventing low-temperature air from entering between the water receiving tray 400 and the base plate 130, so as to avoid the generation of condensate between the water receiving tray 400 and the base plate 130.

[0061] In some specific embodiments of this utility model, such as Figure 6 As shown, there are multiple ribs 131, and the multiple ribs 131 are arranged at intervals along the width direction of the ribs 131.

[0062] The width direction of the rib 131 is perpendicular to the width direction of the housing 100. For example, when multiple ribs 131 are provided on the part of the bottom plate 130 extending in the front-back direction, the multiple ribs 131 can be spaced apart in the front-back direction. When multiple ribs 131 are provided on the part of the bottom plate 130 extending in the vertical direction, the multiple ribs 131 can be spaced apart in the vertical direction.

[0063] By setting multiple ribs 131, the multiple ribs 131 can be used together to compress and seal the first flexible seal 500. The multiple ribs 131 can form a multi-layer seal, which further improves the sealing effect between the ribs 131 and the first flexible seal 500. This more effectively improves the sealing effect between the water receiving tray 400 and the base plate 130, and makes it less likely for low-temperature air to enter between the water receiving tray 400 and the base plate 130, thus more effectively preventing the generation of condensate between the water receiving tray 400 and the base plate 130.

[0064] In some specific embodiments of this utility model, such as Figure 6 As shown, the rib 131 may include a first inclined surface 132 and a second inclined surface 133 arranged along the width direction of the rib 131. The adjacent ends of the first inclined surface 132 and the second inclined surface 133 protrude toward the first flexible seal 500 and are connected to each other.

[0065] In other words, the first inclined surface 132 and the second inclined surface 133 of the rib 131 can be constructed in a "V" shape. That is, the cross-sectional area of ​​the side of the rib 131 facing the first flexible seal 500 can be smaller, thereby making the contact area between the first flexible seal 500 and the rib 131 smaller. The rib 131 can more reliably press the first flexible seal 500 to avoid gaps between the rib 131 and the first flexible seal 500, further improving the sealing between the base plate 130 and the water tray 400. Low-temperature air is less likely to enter between the base plate 130 and the water tray 400, thereby preventing condensation from forming between the water tray 400 and the base plate 130.

[0066] In some specific embodiments of this utility model, such as Figure 2 As shown, the base plate 130 may include a main body 134, which is supported below the water receiving tray 400. The support of the water receiving tray 400 by the main body 134 makes the water receiving tray 400 stably installed in the duct unit 1 and can improve the overall structural strength of the duct unit 1.

[0067] The base plate 130 may also include a bent portion 135, which is connected to the front end of the main body 134 and bent upward relative to the main body 134. The front side of the water receiving tray 400 abuts against the bent portion 135. With this arrangement, the bent portion 135 can be used to limit the water receiving tray 400 in the front-rear direction of the duct unit 1, preventing the water receiving tray 400 from moving in the front-rear direction, so that the water receiving tray 400 is stably fixed inside the housing 100.

[0068] Both the main body 134 and the bent portion 135 are provided with at least one rib 131. That is, one rib 131 can be provided on the main body 134 and the bent portion 135 respectively; or, one rib 131 can be provided on one of the main body 134 and the bent portion 135, and multiple ribs 131 can be provided on the other.

[0069] This design ensures that both the main body 134 and the bent portion 135 are provided with ribs 131, thereby improving the sealing effect between the main body 134 and the first flexible seal 500, as well as the sealing effect between the bent portion 135 and the first flexible seal 500. This ensures that the overall sealing performance of the base plate 130 and the first flexible seal 500 is good. The first flexible seal 500 can better fill the gap between the base plate 130 and the water tray 400, thereby improving the sealing performance between the base plate 130 and the water tray 400 and preventing low-temperature air from entering between the base plate 130 and the water tray 400 and causing condensation.

[0070] Furthermore, such as Figure 2 As shown, a portion of the first flexible seal 500 is located between the main body 134 and the bottom of the water receiving tray 400, and a portion of the first flexible seal 500 is located between the bent portion 135 and the front side of the water receiving tray 400.

[0071] In other words, a portion of the first flexible seal 500 can extend between the main body 134 and the water receiving tray 400, and another portion of the first flexible seal 500 can extend between the bending portion 135 and the water receiving tray 400. Furthermore, by using multiple ribs 131 to press different positions of the first flexible seal 500, the first flexible seal 500 can better fit between the main body 134 and the water receiving tray 400, and between the bending portion 135 and the water receiving tray 400. This arrangement improves the sealing performance between the main body 134 and the water receiving tray 400, and also improves the sealing performance between the bending portion 135 and the water receiving tray 400, thereby better preventing low-temperature air from entering between the water receiving tray 400 and the base plate 130.

[0072] In some specific embodiments of this utility model, such as Figure 2 and Figure 10 As shown, the lower edge of the front side of the water receiving tray 400 is constructed with an arc-shaped transition surface 410, and the first flexible seal 500 is attached to the arc-shaped transition surface 410.

[0073] Understandably, the first flexible seal 500 extends from the front side of the water tray 400 to the lower side of the water tray 400. By constructing an arc-shaped transition surface 410 at the lower edge of the front side of the water tray 400, the middle part of the first flexible seal 500 can better fit into the arc-shaped transition surface 410. In this way, the first flexible seal 500 can better fill and seal the gap between the water tray 400 and the base plate 130. Low-temperature air is less likely to flow into the gap between the water tray 400 and the base plate 130, thus more effectively avoiding the problem of condensation between the water tray 400 and the base plate 130.

[0074] In some specific embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 8 As shown, the duct unit 1 may also include a fan baffle 600, which is disposed inside the housing 100 and located between the heat exchanger 200 and the fan assembly 300. The fan assembly 300 is connected to the fan baffle 600, and the rear side of the water receiving pan 400 abuts against the fan baffle 600.

[0075] By placing the fan baffle 600 between the heat exchanger 200 and the fan assembly 300, the fan baffle 600 can isolate the heat exchanger 200 and the fan assembly 300, avoiding mutual interference between them. In addition, the fan baffle 600 can be used to fix the fan assembly 300, so that the fan assembly 300 is stably fixed inside the casing 100.

[0076] Furthermore, by abutting the rear side of the water tray 400 against the fan baffle 600, the fan baffle 600 can limit the water tray 400 in the front-rear direction of the duct unit 1. That is, the fan baffle 600 and the bent portion 135 of the base plate 130 can jointly limit the water tray 400 in the front-rear direction, so that the water tray 400 is stably fixed inside the housing 100. Moreover, the rear side of the water tray 400 and the fan baffle 600 can be sealed to prevent air from entering the bottom of the water tray 400 and the base plate 130 through the gap between the water tray 400 and the fan baffle 600.

[0077] In addition, a limiting plate 610 can be provided on the fan partition 600. The limiting plate 610 can be located adjacent to the upper side of the water receiving tray 400 along the height direction of the fan partition 600. This arrangement can use the limiting plate 610 to press down the upper side of the water receiving tray 400 to limit the water receiving tray 400 in the vertical direction, thereby further improving the reliability of the water receiving tray 400 in the housing 100.

[0078] At least one of the fan baffle 600 and the water receiving tray 400 is provided with a boss 620, the boss 620 extends along the width direction of the duct machine 1, and the boss 620 protrudes from the side of the fan baffle 600 facing the water receiving tray 400, and / or the boss 620 protrudes from the side of the water receiving tray 400 facing the fan baffle 600.

[0079] The fact that at least one of the fan baffle 600 and the water receiving tray 400 is provided with a boss 620 means that a boss 620 can be provided on the fan baffle 600; or, a boss 620 can be provided on the water receiving tray 400; or, a boss 620 can be provided on both the fan baffle 600 and the water receiving tray 400.

[0080] This design serves two purposes: firstly, the boss 620 enhances the structural strength of the fan baffle 600, making it less prone to deformation and thus reliably supporting and fixing the fan assembly 300; secondly, the boss 620 improves the sealing between the fan baffle 600 and the water tray 400, preventing air from entering the bottom of the water tray 400 and the base plate 130 through the gap between the water tray 400 and the fan baffle 600.

[0081] Furthermore, such as Figure 3 As shown, the duct unit 1 may further include a second flexible seal 700, which is fitted between the rear side of the drip tray 400 and the fan baffle 600 to fill the gap between the drip tray 400 and the fan baffle 600. For example, the second flexible seal 700 may be a sponge, but is not limited thereto.

[0082] By using the second flexible seal 700 to fill the gap between the rear side of the water receiving tray 400 and the fan baffle 600, the gap between the rear side of the water receiving tray 400 and the fan baffle 600 can be prevented from being too large. This can result in a better seal between the rear side of the water receiving tray 400 and the fan baffle 600, preventing ambient temperature air from entering between the water receiving tray 400 and the base plate 130 through the gap between the rear side of the water receiving tray 400 and the fan baffle 600. This can also prevent ambient temperature air and low temperature air from merging and producing condensation between the water receiving tray 400 and the base plate 130.

[0083] In addition, by setting the boss 620 to compress the second flexible seal 700, the contact area between the boss 620 and the second flexible seal 700 can be smaller, and the pressure of the water receiving tray 400 and / or the fan baffle 600 on the second flexible seal 700 at the boss 620 can be larger. In this way, the boss 620 can be used to press the second flexible seal 700, thereby improving the sealing effect between the water receiving tray 400 and / or the fan baffle 600 and the second flexible seal 700 at the boss 620, avoiding the formation of gaps between the water receiving tray 400 and / or the fan baffle 600 and the second flexible seal 700. This can more effectively prevent room temperature air from entering between the water receiving tray 400 and the bottom plate 130 through the gap between the rear side of the water receiving tray 400 and the fan baffle 600, thereby preventing room temperature air and low temperature air from merging and producing condensation between the water receiving tray 400 and the bottom plate 130.

[0084] In some specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the width of the boss 620 is greater than the width of the rib 131.

[0085] Understandably, the height of the fan baffle 600 in the vertical direction is much greater than the height of the bent portion 135 of the base plate 130 in the vertical direction. There is sufficient space on the fan baffle 600 to accommodate a wider boss 620, resulting in a more rational structural design. Furthermore, by making the boss 620 wider, the structural strength of the fan baffle 600 can be significantly improved, making it less prone to deformation.

[0086] Furthermore, it is understood that the main purpose of this invention is to prevent low-temperature air after heat exchange in the heat exchanger 200 from entering the space between the bottom of the water receiving tray 400 and the bottom plate 130 through the gap between the water receiving tray 400 and the bottom plate 130. As long as less low-temperature air enters the space between the water receiving tray 400 and the bottom plate 130, excessive condensation can be avoided. Therefore, by setting the width of the rib 131 to be smaller, the contact area between the rib 131 and the first flexible seal 500 can be smaller, thereby allowing the rib 131 to press firmly against the first flexible seal 500, improving the sealing effect between the front side of the water receiving tray 400 and the bottom plate 130, and more effectively preventing low-temperature air from entering the space between the water receiving tray 400 and the bottom plate 130.

[0087] The following description, with reference to the accompanying drawings, describes a ductwork unit 1 according to an embodiment of the present invention.

[0088] According to an embodiment of the present utility model, the duct air conditioner 1 may include a housing 100, on which an air inlet 110 and an air outlet 120 are formed on opposite sides, and the housing 100 has a base plate 130, so that air can flow into the duct air conditioner 1 through the air inlet 110 and flow into the room through the air outlet 120.

[0089] The ducted air conditioner 1 may include a heat exchanger 200, which is located inside the casing 100 and adjacent to the air outlet 120. After air exchanges heat with the heat exchanger 200 to form a heat exchange airflow, it can flow into the room through the air outlet 120 to achieve cooling or heating of the room. For example, when the heat exchanger 200 acts as an evaporator, ambient temperature air flows through the heat exchanger 200 and its temperature decreases to form low-temperature air. This low-temperature air then flows into the room through the air outlet, thereby achieving cooling of the room.

[0090] The ducted air conditioner 1 may include a fan assembly 300, which is located inside the casing 100 and adjacent to the air inlet 110. The fan assembly 300 drives air to enter the casing 100 from the air inlet 110, and after exchanging heat with the heat exchanger 200, the air enters the room through the air outlet 120. This arrangement allows the fan assembly 300 to draw outside air into the casing 100, thus guiding the airflow and improving the air volume through the ducted air conditioner 1, thereby increasing the heat exchange efficiency between the air and the heat exchanger 200.

[0091] The ducted air conditioner 1 may include a fan baffle 600, which is disposed within the housing 100 and located between the heat exchanger 200 and the fan assembly 300. The fan assembly 300 is connected to the fan baffle 600. In this way, the fan baffle 600 can be used to isolate the heat exchanger 200 and the fan assembly 300, avoiding mutual interference between them. Moreover, the fan baffle 600 can be used to fix the fan assembly 300, so that the fan assembly 300 is stably fixed within the housing 100.

[0092] The ducted air conditioner 1 may also include a drip tray 400, which is located inside the housing 100 and below the heat exchanger 200. Understandably, when the ducted air conditioner 1 is cooling, the heat exchanger 200 acts as an evaporator. Since the surface temperature of the evaporator is lower than the air dew point temperature, water vapor in the air condenses into water droplets. The drip tray 400 collects these dripping condensates to prevent leakage and contamination of the walls or other components inside the ducted air conditioner 1.

[0093] The duct unit 1 may also include a first flexible seal 500, which is fitted between the drip tray 400 and the base plate 130 to fill the gap between them. For example, the first flexible seal 500 may be a sponge, but is not limited thereto.

[0094] By using the first flexible seal 500 to fill the gap between the water receiving tray 400 and the base plate 130, the gap between the water receiving tray 400 and the base plate 130 can be prevented from being too large, thereby improving the sealing performance between the water receiving tray 400 and the base plate 130, preventing low-temperature air from entering between the water receiving tray 400 and the base plate 130, and thus preventing condensation from forming between the water receiving tray 400 and the base plate 130.

[0095] The duct unit 1 may also include a second flexible seal 700, which is fitted between the rear side of the drip tray 400 and the fan baffle 600 to fill the gap between the drip tray 400 and the fan baffle 600. For example, the second flexible seal 700 may be a sponge, but is not limited thereto.

[0096] By using the second flexible seal 700 to fill the gap between the rear side of the water receiving tray 400 and the fan baffle 600, the gap between the rear side of the water receiving tray 400 and the fan baffle 600 can be prevented from being too large. This can result in a better seal between the rear side of the water receiving tray 400 and the fan baffle 600, preventing ambient temperature air from entering between the water receiving tray 400 and the base plate 130 through the gap between the rear side of the water receiving tray 400 and the fan baffle 600. This can also prevent ambient temperature air and low temperature air from merging and producing condensation between the water receiving tray 400 and the base plate 130.

[0097] The base plate 130 is provided with a rib 131, which extends along the width direction of the duct machine 1 and protrudes from the side of the base plate 130 facing the first flexible seal 500.

[0098] The contact area between the rib 131 and the first flexible seal 500 can be relatively small. Under the same force, the pressure of the rib 131 on the first flexible seal 500 can be greater. This allows the rib 131 to press the first flexible seal 500 tightly, thereby improving the sealing effect between the base plate 130 and the first flexible seal 500 at the rib 131. This prevents gaps from forming between the base plate 130 and the first flexible seal 500, and makes it difficult for the low-temperature air cooled by the heat exchanger to enter between the base plate 130 and the water receiving tray 400.

[0099] Additionally, the fan partition 600 is provided with a boss 620, which extends along the width direction of the duct machine 1 and protrudes from the side of the fan partition 600 facing the second flexible seal 700.

[0100] The contact area between the boss 620 and the second flexible seal 700 can be relatively small, and the pressure exerted by the fan baffle 600 on the second flexible seal 700 at the boss 620 can be relatively large. This allows the boss 620 to press the second flexible seal 700 tightly, thereby improving the sealing effect between the fan baffle 600 and the second flexible seal 700 at the boss 620 and preventing gaps from forming between the fan baffle 600 and the second flexible seal 700. This effectively prevents ambient temperature air from entering the gap between the water receiving pan 400 and the bottom plate 130 through the rear side of the water receiving pan 400 and the fan baffle 600, and further prevents ambient temperature air and low temperature air from merging and producing condensation between the water receiving pan 400 and the bottom plate 130.

[0101] Thus, the duct air conditioner 1 according to the present utility model embodiment can not only improve the sealing effect between the front side of the water receiving tray 400 and the base plate 130 by using the ribs 131 on the base plate 130, but also improve the sealing effect between the rear side of the water receiving tray 400 and the fan partition 600 by using the bosses 620 on the fan partition 600, thereby avoiding the mixing of low temperature air and normal temperature air between the water receiving tray 400 and the base plate 130 to produce condensate.

[0102] Other components and operations of the ductwork unit 1 according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0103] The ducted air conditioner 1 of this invention performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0104] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0105] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the ducted air conditioner 1 regulates the temperature and humidity of the indoor space.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0107] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
