Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly provides a water receiving tray and an air conditioner including the water receiving tray. Background Art

[0002] The conventional installation of a ducted air conditioner is to hang it above the ceiling through hangers, and it is usually designed for horizontal installation. A water receiving tray is provided below the heat exchanger. When the heat exchanger is horizontally installed, the water flowing down from the heat exchanger will flow into the water receiving tray. However, in some special occasions, it is necessary to rotate the ducted air conditioner by 90 degrees for vertical installation. How to ensure the safety of the water generated by the heat exchanger during vertical installation becomes a key problem for the vertical installation of the ducted air conditioner.

[0003] In the prior art, although the water receiving tray can hold the condensed water when the ducted air conditioner is horizontally installed, when the ducted air conditioner is changed to vertical installation, due to the reversal of the heat exchanger, the condensed water of the heat exchanger cannot flow into the water receiving tray. The condensed water flowing outside the water receiving tray will not only cause the machine to leak water and pollute the user's floor, but on the other hand, if the electrical box is located on the side of the heat exchanger before the heat exchanger is reversed, after vertical installation, the electrical box will be located below the heat exchanger.

[0004] Therefore, in the prior art, either the horizontal ducted air conditioner is prohibited from being vertically installed, or the electrical box needs to be completely removed and reinstalled on the side of the heat exchanger during vertical installation. Otherwise, the condensed water may flow into the electrical box body, causing the computer board to catch fire and resulting in huge losses. Therefore, this has increased the installation workload and cost.

[0005] Correspondingly, there is a need in the art for a new water receiving tray to solve the problem of water leakage when the existing horizontal air conditioner is vertically installed. Summary of the Invention

[0006] The present invention aims to solve the above technical problems, that is, to solve the problem of water leakage when the existing horizontal air conditioner is vertically installed.

[0007] In a first aspect, the present invention provides a water receiving tray, which includes a first water receiving portion, a second water receiving portion, and a third water receiving portion; the heat exchanger includes a heat exchanger body and heat exchange tubes exposed on the side of the heat exchanger body;

[0008] The first water receiving portion is used to hold the condensed water on the heat exchanger body and the heat exchange tubes when the air conditioner is horizontally installed;

[0009] When the air conditioner is vertically installed, the projection of the heat exchange tubes in the vertical direction all falls within the second water receiving portion and the third water receiving portion; the second water receiving portion is used to hold the condensed water on the heat exchanger body and the lower part of the heat exchange tubes during vertical installation, and the third water receiving portion is used to hold the condensed water on the upper part of the heat exchange tubes during vertical installation.

[0010] In the case of adopting the above technical solution, when the air conditioner is installed vertically, the second water receiving part receives the condensed water on the heat exchanger body. The water receiving tray of the present invention also extends the second water receiving part below the heat exchange tubes and simultaneously arranges a third water receiving part, so that the projection of the side heat exchange tubes in the vertical direction all falls into the second water receiving part and the third water receiving part, and all the condensed water generated by the heat exchange tubes falls into the second water receiving part and the third water receiving part, thereby avoiding the leakage of the condensed water from the heat exchange tubes.

[0011] Therefore, the water receiving tray of the present invention can enable all the condensed water on the heat exchanger body and the heat exchange tubes to enter the water receiving tray whether the air conditioner is installed horizontally or vertically, effectively preventing the leakage of condensed water.

[0012] In an optional technical solution of the above air conditioner, the first water receiving part includes a first bottom plate, the second water receiving part includes a second bottom plate, the third water receiving part includes a third bottom plate, the second bottom plate is respectively connected to the first bottom plate and the third bottom plate, and a first water baffle is arranged around the peripheries of the first bottom plate, the second bottom plate and the third bottom plate.

[0013] In the case of adopting the above technical solution, water can be discharged through fewer drain holes.

[0014] In an optional technical solution of the above air conditioner, the first water receiving part, the second water receiving part and the third water receiving part are integrally formed.

[0015] In the case of adopting the above technical solution, the production process is simplified and the production cost is reduced.

[0016] In an optional technical solution of the above air conditioner, the first water receiving part includes a first bottom plate, the second water receiving part includes a second bottom plate, the second bottom plate is connected to the first bottom plate, a first water baffle is arranged around the peripheries of the first bottom plate and the second bottom plate, the third water receiving part includes a third bottom plate, a second water baffle is arranged around the periphery of the third bottom plate to form an opening, the opening faces the second water receiving part, and the condensed water in the third water receiving part enters the second water receiving part through the opening.

[0017] In the case of adopting the above technical solution, the third water receiving part and the second water receiving part can share a drain hole, and the independent arrangement of the third water receiving part can remove the third water receiving part when the air conditioner is installed horizontally to reduce the weight of the air conditioner.

[0018] In an optional technical solution of the above air conditioner, the second water baffle forms a water baffle cover, the water baffle cover covers the heat exchange tubes inside it, and a hole structure for the heat exchange tubes to extend out is arranged on the water baffle cover.

[0019] In the case of adopting the above technical solution, the condensed water on the heat exchange tubes is thus prevented from splashing due to vibration.

[0020] In a second aspect, the present invention provides an air conditioner, which includes a heat exchanger and a water receiving tray;

[0021] The heat exchanger includes a heat exchanger body and heat exchange tubes exposed on the side of the heat exchanger body;

[0022] The heat exchanger includes a heat exchanger body and heat exchange tubes exposed on the side of the heat exchanger body;

[0023] The water receiving tray includes a first water receiving portion, a second water receiving portion and a third water receiving portion;

[0024] The first water receiving portion is used to receive the condensed water on the heat exchanger body and the heat exchange tubes when the air conditioner is installed horizontally;

[0025] When the air conditioner is installed vertically, the projection of the heat exchange tubes in the vertical direction entirely falls within the second water receiving portion and the third water receiving portion; the second water receiving portion is used to receive the condensed water on the heat exchanger body and the lower part of the heat exchange tubes during vertical installation, and the third water receiving portion is used to receive the condensed water on the upper part of the heat exchange tubes during vertical installation.

[0026] In the case of adopting the above technical solution, the present invention sets the third water receiving portion, so that the projection of the side heat exchange tubes in the vertical direction entirely falls within the second water receiving portion and the third water receiving portion, and all the condensed water generated by the heat exchange tubes falls into the second water receiving portion and the third water receiving portion, thereby avoiding the leakage of the condensed water from the heat exchange tubes.

[0027] Therefore, whether the air conditioner of the present invention is installed vertically or horizontally, it can ensure that the condensed water on the heat exchanger all enters the water receiving tray, avoiding the leakage of the condensed water.

[0028] In an optional technical solution of the above air conditioner, the air conditioner further includes an electrical box. When the air conditioner is installed horizontally, the electrical box is located on the side of the heat exchange tubes; when the air conditioner is installed vertically, the electrical box is located below the heat exchange tubes; a partition is provided between the water receiving tray and the electrical box.

[0029] In the case of adopting the above technical solution, it is to prevent the water overflowing from the water receiving tray from entering the electrical box.

[0030] In an optional technical solution of the above air conditioner, the edge of the partition is provided with a first flanging bent towards the heat exchanger.

[0031] In the case of adopting the above technical solution, when installed vertically, if the heat exchanger generates too much condensed water, causing the water receiving tray to be unable to drain in time and overflowing outward, the first flanging can further prevent the condensed water from overflowing into the electrical box.

[0032] In an alternative technical solution of the above air conditioner, the electrical box includes a top plate, and a second flanging bent toward the heat exchanger is provided at the edge of the top plate.

[0033] In the case of adopting the above technical solution, the second flanging can further prevent the condensed water from seeping into the interior of the electrical box along the edge of the top of the electrical box, ensuring the dryness inside the electrical box.

[0034] In an alternative technical solution of the above air conditioner, a convex portion is provided inside the first water receiving portion, and one end of the heat exchanger body abuts against the convex portion; and / or, a support plate is provided on the first water receiving portion, and the heat exchanger body is connected to the support plate during vertical installation.

[0035] In the case of adopting the above technical solution, one end of the heat exchanger body abuts against the convex portion to improve the installation stability of the heat exchanger. A support plate is provided on the first water receiving portion to connect the heat exchanger, which not only ensures the stability of the heat exchanger but also ensures the stable connection between the water receiving tray and the heat exchanger, maintaining the position of the water receiving tray.

[0036] Those skilled in the art can understand that the water receiving tray of the present invention includes a first water receiving portion, a second water receiving portion, and a third water receiving portion; the heat exchanger includes a heat exchanger body and heat exchange tubes exposed on the side of the heat exchanger body. The first water receiving portion is used to receive the condensed water on the heat exchanger body and the heat exchange tubes when the air conditioner is installed horizontally.

[0037] When the air conditioner is installed vertically, the projection of the heat exchange tubes in the vertical direction all falls within the second water receiving portion and the third water receiving portion; the second water receiving portion is used to receive the condensed water on the heat exchanger body and the lower part of the heat exchange tubes during vertical installation, and the third water receiving portion is used to receive the condensed water on the upper part of the heat exchange tubes during vertical installation.

[0038] In the case of adopting the above technical solution, when the air conditioner is installed vertically, the second water receiving portion receives the condensed water on the heat exchanger body. The water receiving tray of the present invention also extends the second water receiving portion below the heat exchange tubes and simultaneously provides a third water receiving portion, so that the projection of the side heat exchange tubes in the vertical direction all falls within the second water receiving portion and the third water receiving portion, and all the condensed water generated by the heat exchange tubes falls into the second water receiving portion and the third water receiving portion, thereby avoiding the leakage of the condensed water from the heat exchange tubes.

[0039] Therefore, the water receiving tray of the present invention can enable all the condensed water on the heat exchanger body and the heat exchange tubes to enter the water receiving tray whether the air conditioner is installed horizontally or vertically, effectively preventing the leakage of condensed water.

[0052] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios. For example, although the air conditioner of the present invention is described by taking the ducted air conditioner as an example, the air conditioner of the present invention is not limited to the ducted air conditioner, and it can also be other types of air conditioners, such as wall-mounted air conditioners or cabinet air conditioners, etc.

[0053] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "vertical", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0054] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0055] Referring to Figure 1 , the ducted air conditioner of the present invention includes a heat exchange part 1 and an electrical box 2. The electrical box 2 is equipped with core components for controlling the operation of the ducted air conditioner, including a main control computer board, a power module, a signal processing unit and other components.

[0056] The heat exchange part 1 includes a heat exchanger and a water receiving tray 13. The heat exchanger includes a heat exchanger body 11 and heat exchange tubes 12 exposed on the side of the heat exchanger body 11.

[0057] The heat exchange tubes 12 include an inlet liquid header and an outlet liquid header. The inlet liquid header and the outlet liquid header are respectively connected to the internal tube bundles of the heat exchanger body 11, and are used for distributing and collecting the refrigerant to form a refrigerant circuit, so that the medium circulates inside the heat exchanger body 11, realizing the input and output of the refrigerant inside the heat exchanger body 11, and ensuring effective heat transfer.

[0058] Furthermore, a partition 14 is provided between the water receiving tray 13 and the electrical box 2. Referring to Figure 1 , when the ducted air conditioner is installed horizontally, the electrical box 2 is located on the side of the heat exchange tubes 12. Referring to Figure 3, when the air duct machine is installed vertically, the air duct machine rotates 90°, the electrical box 2 is located below the heat exchange tubes 12, and the electrical box 2 and the water receiving tray 13 are separated by a partition 14. Of course, the electrical box 2 can also be replaced with other components, which can be set by those skilled in the art according to actual needs.

[0059] Refer to Figure 1 and Figure 2 , the water receiving tray 13 includes a first water receiving part 131, a second water receiving part 132 and a third water receiving part 133. The first water receiving part 131 is used to receive the condensed water on the heat exchanger body 11 and the heat exchange tubes 12 during horizontal installation.

[0060] Refer to Figure 3 and Figure 4 , during vertical installation, the projection of the heat exchange tubes 12 in the vertical direction all falls within the second water receiving part 132 and the third water receiving part 133. The second water receiving part 132 is used to receive the condensed water on the heat exchanger body 11 and the lower part of the heat exchange tubes 12 during vertical installation. The third water receiving part 133 is used to receive the condensed water on the upper part of the heat exchange tubes 12 during vertical installation.

[0061] During horizontal installation, the electrical box 2 is located on the side of the heat exchange tubes 12, and the condensed water on the heat exchanger body 11 and the side heat exchange tubes 12 can flow into the first water receiving part 131 under the action of gravity.

[0062] However, during vertical installation, after the entire air duct machine rotates 90°, the electrical box 2 is located below the heat exchange part 1. The inventor found that since the heat exchange tubes 12 on the side of the heat exchanger body 11 are relatively dense, there are certain gaps between the pipelines and the pipeline shapes are irregular. Therefore, during vertical installation, the water on the surface of the heat exchange tubes 12 cannot flow downward along the surface and gather at the bottom and then enter the water receiving tray 13, but instead drips dispersedly. Therefore, the condensed water generated by the heat exchange tubes 12 on the side of the heat exchanger is the main reason for the leakage of condensed water to the electrical box 2 during vertical installation, and also makes the transformation cost soar during vertical installation.

[0063] Since the second water receiving part 132 also needs to avoid the fan below the heat exchanger, it cannot cover the entire projection of the heat exchanger body 11 in the vertical direction. The surface of the heat exchanger body 11 is relatively smooth and the shape is regular. Therefore, the condensed water can flow from the top to the bottom along the surface of the heat exchanger body 11 into the second water receiving part 132. Therefore, even if the second water receiving part 132 cannot cover the entire projection of the heat exchanger body 11 in the vertical direction, it can still collect all the condensed water on the heat exchanger body 11.

[0064] However, when installed vertically, if only by extending the second water receiving part 132 to the position of the heat exchange tube 12, it can only receive part of the condensed water at the lower part of the heat exchange tube 12, and still cannot smoothly receive all the condensed water generated by the heat exchange tube 12. Therefore, in order to ensure the safety of the electrical box 2 during vertical installation, the present invention provides a third water receiving part 133 to receive the condensed water at the upper part of the heat exchange tube 12, so that the projection of the side heat exchange tube 12 in the vertical direction completely falls into the second water receiving part 132 and the third water receiving part 133, and all the condensed water generated by the heat exchange tube 12 completely falls into the second water receiving part 132 and the third water receiving part 133, thereby preventing the condensed water of the heat exchange tube 12 from flowing into the electrical box 2.

[0065] Therefore, when the air duct machine of the present invention is installed vertically, the position of the electrical box 2 can be ensured without changing, thereby eliminating the need to increase the workload of modification and reducing the cost of vertical installation.

[0066] It should be noted that when installed vertically, the partition 14 can be used as the top plate of the electrical box 2, or a separate top plate 21 of the electrical box 2 can be provided below the partition 14 according to needs. Those skilled in the art can set it according to actual needs, and all fall within the protection scope of the present invention. In addition, when installed vertically, the lengths of the U-shaped tubes extending from both sides of the heat exchanger body 11 are very short, so the condensed water generated by it is very little and can be ignored.

[0067] Of course, those skilled in the art can also cancel the partition 14 according to actual needs and directly set the electrical box 2 below the water receiving tray 13, and all fall within the protection scope of the present invention.

[0068] Refer to Figure 1 , in a possible implementation manner, the air duct machine includes a heat exchange part 1 and an electrical box 2, and the heat exchange part 1 includes a heat exchanger and a water receiving tray 13.

[0069] The heat exchanger includes a heat exchanger body 11 and heat exchange tubes 12 exposed on the side of the heat exchanger body 11.

[0070] A partition 14 is provided between the water receiving tray 13 and the electrical box 2. When the air duct machine is installed horizontally, the electrical box 2 is located on the side of the heat exchange tube 12, and when the air duct machine is installed vertically, the electrical box 2 is located below the heat exchange tube 12.

[0071] Refer to Figures 1 to 4, the water receiving tray 13 includes a first water receiving part 131, a second water receiving part 132, and a third water receiving part 133. The first water receiving part 131 includes a first bottom plate 1311, the second water receiving part 132 includes a second bottom plate 1321, and the third water receiving part 133 includes a third bottom plate 1331. The first bottom plate 1311, the second bottom plate 1321, and the third bottom plate 1331 are connected to each other, and a first water baffle 135 is arranged around the circumferential sides of the first bottom plate 1311, the second bottom plate 1321, and the third bottom plate 1331 to enclose a box-shaped structure for collecting condensed water. Optionally, the first water receiving part 131, the second water receiving part 132, and the third water receiving part 133 are integrally formed to simplify the process and reduce costs.

[0072] The first water receiving part 131 is used to receive the condensed water flowing down from the heat exchanger body 11 and the heat exchange tubes 12 during horizontal installation. The projection of the heat exchange tubes 12 in the vertical direction all falls within the second water receiving part 132 and the third water receiving part 133. The second water receiving part 132 is used to receive the condensed water at the lower part of the heat exchanger body 11 and the heat exchange tubes 12 during vertical installation, and the third water receiving part 133 is used to receive the condensed water at the upper part of the heat exchange tubes 12 during vertical installation.

[0073] Optionally, the first water receiving part 131, the second water receiving part 132, and the third water receiving part 133 can be integrally formed by processes such as injection molding or stamping. Or, each water receiving part can also be manufactured separately and then welded and spliced. Those skilled in the art can set the manufacturing process of the water receiving tray 13 according to actual needs. The present invention does not impose any restrictions on the manufacturing process and all fall within the protection scope of the present invention.

[0074] Further, a drain hole 134 is arranged near the connection of the first water receiving part 131, the second water receiving part 132, and the third water receiving part 133. The drain hole 134 is connected to a drain pipe (not shown in the figure). The first water receiving part 131, the second water receiving part 132, and the third water receiving part 133 can share a drain hole 134 to drain the condensed water to the drain pipe, and the drain pipe drains the condensed water outside the air duct machine to simplify the structure and save costs.

[0075] Further, when the air duct machine is horizontally installed, the projections of the heat exchanger body 11 and the heat exchange tubes 12 in the vertical direction all fall within the first water receiving part 131. Of course, those skilled in the art can also, according to actual needs, make the projections of the heat exchanger body 11 and the heat exchange tubes 12 in the vertical direction not all fall within the first water receiving part 131, as long as the first water receiving part 131 can collect all the condensed water during horizontal installation, and all fall within the protection scope of the present invention.

[0076] Or, referring to Figure 8In an alternative embodiment, the first bottom plate 1311 and the second bottom plate 1321 are connected, and optionally, the first bottom plate 1311 and the second bottom plate 1321 are integrally formed. A first water baffle 135 is provided on the peripheral side of the first bottom plate 1311 and the second bottom plate 1321. The third water receiving portion 133 is provided separately, and a second water baffle is provided on the peripheral side of the third bottom plate 1331, and the second water baffle forms a water baffle cover 1333 and an opening. The third bottom plate 1331 is placed on a first water baffle 135 of the second water receiving portion 132, with the opening facing the second water receiving portion 132, and the bottom of the third bottom plate 1331 is in contact with the partition 14. The condensed water in the third water receiving portion 133 flows into the second water receiving portion 132 from the opening, and then is discharged from the drain hole 134. Optionally, the third water receiving portion 133 is connected to the second water receiving portion 132 and / or the partition 14 to keep it stable.

[0077] The water shield 1333 covers the heat exchange tube 12 inside to prevent condensed water from splashing due to vibration and other reasons. The water shield 1333 is provided with a hole for the heat exchange tube 12 to extend out. The third water receiving part 133 is independently provided, and the third water receiving part 133 can be removed during horizontal installation to reduce the weight of the air duct machine. Of course, those skilled in the art can also set the second water shield to the same structure as the first water shield 135 according to actual needs, and both fall within the protection scope of the present invention.

[0078] Further, refer to Figures 1 to 4 , a triangular support plate 1312 is also provided on the first water receiving portion 131, and the heat exchanger body 11 is connected to the support plate 1312, and the support plate 1312 plays the role of fixing the heat exchanger. The support plate 1312 can be formed integrally on the first water receiving portion 131, or it can be fixed to the first water receiving portion 131 in the form of a separate part by bolts or rivets, etc., and those skilled in the art can set it according to actual needs, and all fall within the protection scope of the present invention. Furthermore, a protrusion 1313 is provided in the first water receiving portion 131. The protrusion 1313 extends along the bottom end of the heat exchanger body 11. When the heat exchanger is installed at an angle, the bottom end of the heat exchanger body 11 rests on the protrusion 1313 to improve the installation stability.

[0079] Further, refer to Figure 3 A plurality of first flanges 141 bent toward the heat exchanger are provided at the edge of the partition 14, and adjacent first flanges 141 are sealed and connected by full welding. When installed vertically, if the heat exchanger generates too much condensed water, the water receiving pan 13 cannot be discharged in time, so that the water overflows, the first flanges 141 can prevent the condensed water from overflowing into the electrical box 2.

[0080] Reference Figure 5 and Figure 6, a recess 1332 is formed at the bottom of the third bottom plate 1331, and a space for the electrical box 2 to route wires is formed between the partition 14 and the recess 1332.

[0081] Referring to Figure 7 , the electrical box 2 includes a top plate 21, side plates 22 and a bottom plate 23 connected to form a box body. The top plate 21 is located below the partition 14, and a plurality of second flanges 24 bent toward the heat exchanger are formed at the edge of the top plate 21. The adjacent two second flanges 24 are fully welded to seal the gap. The second flange 24 can further prevent condensed water from seeping into the interior of the electrical box 2 along the edge of the top of the electrical box 2, ensuring the dryness inside the electrical box 2.

[0082] However, it should be noted that the present invention does not limit the sealing method of the gap between two adjacent first flanges 141 or two adjacent second flanges 24. The adjacent flanges can also be integrally formed by stamping, casting, etc. to avoid gaps, or sealed by sealant, gasket, etc., and all fall within the protection scope of the present invention. In addition, only one first flange 141 or second flange 24 can be provided according to actual needs, or multiple non-adjacent flanges can be provided, which do not deviate from the principle of the present invention and all fall within the protection scope of the present invention.

[0083] In summary, the air duct machine of the present invention is compatible with both horizontal and vertical installation methods, and through a three-dimensional multi-stage waterproof structure, it ensures that the condensed water can be discharged from the air duct machine during vertical installation, preventing the condensed water from entering the electrical box 2 and ensuring the reliability of the operation of the air duct machine.

[0084] As described in the first paragraph of this section, the above embodiments are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0085] For example, in an alternative embodiment, the first water receiving part 131 and the second water receiving part 132 are integrally formed and communicate with each other, the third water receiving part 133 is separately provided, the second water receiving part 132 and the third water receiving part 133 are separated by a first water baffle 135, and drain holes 134 are respectively provided on the first water receiving part 131 and the third water receiving part 133. Or, the first water receiving part 131, the second water receiving part 132 and the third water receiving part 133 may not communicate with each other, and each water receiving part is surrounded by a water baffle to form an independent box shape, and drain holes 134 are respectively provided on each water receiving part to realize independent drainage of each drainage part. Or, instead of providing drain holes 134 on the water receiving tray 13, the user can manually clean the condensed water in the water receiving tray 13, which does not deviate from the principle of the present invention, so all will fall within the protection scope of the present invention.
