Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a water receiving pan structure and a duct unit. Background Art

[0002] In air conditioners such as ducted air conditioners, a water pan is generally provided under the evaporator to receive the condensed water produced by the evaporator. As the air conditioner is used, the dust or debris carried by the condensed water will increase, which may easily cause odor and blockage. At this time, it needs to be cleaned. However, the water pan is large in size, the disassembly space is limited, and it is not easy to operate. Summary of the invention

[0003] The problem solved by the present invention is how to arrange a water receiving tray structure to at least partially solve the problem that the water receiving tray is large in size and inconvenient to disassemble, assemble and clean.

[0004] To solve the above problems, the present invention provides a water receiving tray structure, including a first water receiving tray and a second water receiving tray, wherein the first water receiving tray is at least partially located below the second water receiving tray, and the first water receiving tray is used to receive water discharged from the second water receiving tray.

[0005] Therefore, compared with the traditional setting method of a water receiving pan, the water receiving pan structure is set to include a first water receiving pan and a second water receiving pan, the second water receiving pan receives and buffers the condensed water, the first water receiving pan receives and discharges the condensed water after buffering by the second water receiving pan, and part of the dust and debris carried in the condensed water remains on the second water receiving pan, and the large particles and debris on the first water receiving pan are reduced. When cleaning the water receiving pan structure, it is only necessary to remove the second water receiving pan and clean the second water receiving pan. The possibility of clogging of the first water receiving pan is small, and the first water receiving pan does not need to be disassembled and assembled but maintains the original installation position, and can continue to realize the water receiving or supporting function of the first water receiving pan itself. To a certain extent, the difficulty and frequency of disassembly and cleaning of the water receiving pan structure are reduced, and it has high reliability and strong practicality.

[0006] Optionally, the second water receiving tray is disposed below the evaporator of the air conditioner, and the second water receiving tray is used to filter condensed water flowing down from the evaporator.

[0007] Thus, the condensed water flowing down from the evaporator is first filtered through the second water receiving pan to remove large particles and debris in the condensed water, thereby reducing the probability of clogging of the first water receiving pan and achieving high reliability.

[0008] Optionally, the second water receiving tray is detachably connected to the first water receiving tray.

[0009] Therefore, the second water receiving tray is configured to be detachably connected to the first water receiving tray, thereby avoiding the need to separately set up a structure for installing the second water receiving tray, saving the installation space required for the water receiving tray structure, and enhancing the connection between the second water receiving tray and the first water receiving tray, thereby increasing the stability and reliability of the water receiving tray structure.

[0010] Optionally, the second water receiving tray is slidably connected to the first water receiving tray, and the second water receiving tray is separable from the first water receiving tray along a sliding direction of the second water receiving tray.

[0011] Therefore, the second water receiving tray is configured to be slidably connected to the first water receiving tray, and the second water receiving tray is separable from the first water receiving tray along the sliding direction of the second water receiving tray. The second water receiving tray can be removed from the first water receiving tray by sliding, which facilitates the disassembly and assembly of the second water receiving tray. After the second water receiving tray is removed, the first water receiving tray retains its original position and can continue to receive condensed water, which is highly practical.

[0012] Optionally, a connecting structure is provided on the side wall of the first water receiving tray, the connecting structure is arranged to penetrate outwardly through at least one side wall of the first water receiving tray, the second water receiving tray is slidably connected to the connecting structure, and the connecting structure is arranged as a through hole or a first opening.

[0013] Thus, the connecting structure is arranged to penetrate outwardly through at least one side wall of the first water receiving tray, and the second water receiving tray can be disassembled and assembled by sliding and pulling horizontally. The water receiving tray structure occupies a small space, is easy to disassemble and clean, and has strong practicality.

[0014] Optionally, a first positioning surface structure is provided on the first water receiving tray, and the first positioning surface structure is located on the side of the first water receiving tray to which the second water receiving tray slides in, and the first positioning surface structure is used to position the second water receiving tray in the sliding direction of the second water receiving tray.

[0015] Thus, one end of the second water receiving tray passes through the connecting structure and contacts the first positioning surface structure, thereby realizing the positioning of the second water receiving tray in the sliding direction of the second water receiving tray, which has high reliability and strong practicality.

[0016] Optionally, a second positioning surface structure is provided on the first water receiving tray, and the second positioning surface structure is located on the first water receiving tray in a direction perpendicular to the sliding direction of the second water receiving tray, and the second positioning surface structure is used for positioning in a direction perpendicular to the sliding direction of the second water receiving tray.

[0017] Therefore, the second water receiving tray is positioned in a direction perpendicular to the sliding direction of the second water receiving tray through the second positioning surface structure, and the sliding of the second water receiving tray can be guided to a certain extent. The sliding of the second water receiving tray is highly stable and practical.

[0018] Optionally, the first water receiving tray comprises a first water receiving tray body and a supporting structure, wherein the supporting structure is disposed at the bottom of the first water receiving tray body, and the supporting structure is used to support the second water receiving tray.

[0019] Therefore, by providing the support structure, the support structure forms a reliable support for the second water receiving tray, and the second water receiving tray has high force stability and strong practicality.

[0020] Optionally, the supporting structure includes at least two step structures, the two step structures are symmetrically arranged, and the step structures are used to limit the displacement of the second water receiving tray.

[0021] Therefore, the two step structures are symmetrically arranged, and the step structure is used to limit the displacement of the second water receiving tray. The two step structures cooperate to limit the displacement of the second water receiving tray, and can also form a sliding channel for the second water receiving tray to a certain extent, and guide the second water receiving tray to slide. The second water receiving tray is reliably limited and has high stability.

[0022] Optionally, the second water receiving tray includes a second water receiving tray body and a water retaining structure, and the water retaining structure is arranged at the bottom of the second water receiving tray body.

[0023] Therefore, by arranging the water retaining structure at the bottom of the second water receiving tray body, the condensed water received by the second water receiving tray is buffered and blocked from decelerating by the water retaining structure, so that more large particles and debris in the condensed water are deposited, thereby reducing the probability of blockage of the water receiving tray structure and achieving high reliability.

[0024] Optionally, the water retaining structure is a water retaining rib.

[0025] Therefore, the water retaining structure is set as a water retaining rib, and the condensed water is buffered and decelerated by the water retaining rib, so that larger particles and debris are deposited, and the structure is simple and practical.

[0026] Optionally, at least two of the water retaining structures are provided, wherein at least two of the water retaining structures are staggered.

[0027] Thus, at least two of the water retaining structures are staggered, and the condensed water is blocked at different positions by staggered arrangement, so that the flow direction of the condensed water is changed, the buffering and blocking effect is good, and the reliability is high.

[0028] Optionally, a second opening is provided at one end of the second water receiving tray body, and the second opening is located on a side wall or a bottom of the second water receiving tray body.

[0029] Therefore, a second opening is provided at one end of the second water receiving tray body, and condensed water flows out from the second opening. Compared with a traditional drain outlet, the second opening is not easily blocked, has a simple structure, and is highly practical.

[0030] Optionally, a filter net is disposed in the second water receiving tray, the filter net at least partially covers the bottom of the second water receiving tray, and the filter net is used to filter water flowing toward the first water receiving tray.

[0031] Therefore, by providing the filter net, the condensed water received by the second water receiving tray is filtered before flowing out, the first water receiving tray is less likely to be blocked, and the cleaning frequency of the water receiving tray structure is lower.

[0032] Another aspect of the present invention provides a duct air conditioner, comprising any one of the above-mentioned water receiving tray structures. The duct air conditioner has the beneficial effects of the water receiving tray structure.

[0033] Optionally, the water receiving tray structure is used to be arranged below the evaporator of the air duct machine, and the second water receiving tray of the water receiving tray structure can slide out relative to the first water receiving tray of the water receiving tray structure.

[0034] Therefore, when the water receiving tray structure is cleaned, the first water receiving tray does not need to be disassembled, and the second water receiving tray can be pulled out by sliding. The required disassembly space is small, the reliability is high, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

For example, the positive direction of the X axis is the direction of the return air outlet in the duct air conditioner.

[0052] In addition, all directions or positional relationships mentioned in the embodiments of this specification are based on the positional relationships in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not imply or suggest that the referred device or element must have a specific orientation, and should not be understood as a limitation on the present invention.

[0053] An embodiment of the present invention provides a water receiving tray structure, including a first water receiving tray 1 and a second water receiving tray 2 , wherein the first water receiving tray 1 is at least partially located below the second water receiving tray 2 , and the first water receiving tray 1 is used to receive water discharged from the second water receiving tray 2 .

[0054] It should be noted that the water receiving tray structure is used to receive condensed water. In the air conditioner, the water receiving tray structure is located below the evaporator or other structures that generate condensed water. However, the second water receiving tray 2 is not limited to being installed on the first water receiving tray 1. The second water receiving tray 2 can also be installed at other locations of the air conditioner, such as on the evaporator or the side wall of the air conditioner shell. Of course, in this case, the installation structure of the second water receiving tray 2 should be adaptively changed to ensure that the first water receiving tray 1 receives the condensed water discharged from the second water receiving tray 2. This will not be described in detail here.

[0055] It should be noted that the first water receiving tray 1 is at least partially located below the second water receiving tray 2. Here, below indicates the direction opposite to the Z-axis in the accompanying drawing. It is sufficient that the portion of the first water receiving tray 1 for receiving condensed water is located below the second water receiving tray 2, or in other words, the bottom wall of the first water receiving tray 1 is located below the second water receiving tray 2.

[0056] The advantage of such a configuration is that, compared with the traditional setting of a water receiving pan, the water receiving pan structure is configured to include a first water receiving pan 1 and a second water receiving pan 2, the second water receiving pan 2 receives condensed water and buffers the condensed water, the first water receiving pan 1 receives and discharges the condensed water buffered by the second water receiving pan 2, and part of the dust and debris carried in the condensed water remains on the second water receiving pan 2, and the large particles and debris on the first water receiving pan 1 are reduced. When cleaning the water receiving pan structure, it is only necessary to remove the second water receiving pan 2 and clean the second water receiving pan 2. The possibility of clogging of the first water receiving pan 1 is small, and the first water receiving pan 1 does not need to be disassembled and assembled but maintains the original installation position, and can continue to realize the water receiving or supporting function of the first water receiving pan 1 itself. To a certain extent, the difficulty and frequency of disassembly and cleaning of the water receiving pan structure are reduced, and the reliability and practicality are strong.

[0057] The second water receiving tray 2 is detachably connected to the first water receiving tray 1. It should be noted that, in some embodiments, the second water receiving tray 2 is directly placed on the first water receiving tray 1, and the second water receiving tray 2 and the first water receiving tray 1 can be connected by at least one of screw connection, clamping and plugging.

[0058] The advantage of such a configuration is that the second water receiving tray 2 is configured to be detachably connected to the first water receiving tray 1, thereby avoiding the need for an additional structure for installing the second water receiving tray 2, saving the installation space required for the water receiving tray structure, and enhancing the connection between the second water receiving tray 2 and the first water receiving tray 1, thereby increasing the stability and reliability of the water receiving tray structure.

[0059] The second water receiving tray 2 is slidably connected to the first water receiving tray 1 , and along the sliding direction of the second water receiving tray 2 , the second water receiving tray 2 and the first water receiving tray 1 are separable.

[0060] It should be noted that the sliding connection means that the two are in contact but not fixed, and the two can slide relative to each other. In some embodiments, the second water receiving tray 2 is slidably connected to the first water receiving tray 1 via a guide rail slider. For example, the first water receiving tray 1 is provided with one of the guide rail and the slider in the vertical direction (Z-axis direction in the accompanying drawings) or the horizontal direction (any direction in the XY plane in the accompanying drawings), and the second water receiving tray 2 is provided with the other of the guide rail and the slider, and the guide rail and the slider are slidably connected. The above enumeration illustrates the specific structure of the sliding connection between the second water receiving tray 2 and the first water receiving tray 1, but it should not be limited to this. For example, the guide rail may not be provided in the vertical direction or the horizontal direction, as long as it can slide out of the water receiving tray structure. In addition, along the sliding direction of the second water receiving tray 2, the second water receiving tray 2 and the first water receiving tray 1 can be separated to facilitate disassembly and assembly.

[0061] The advantage of such a configuration is that the second water receiving tray 2 is configured to be slidably connected to the first water receiving tray 1, and the second water receiving tray 2 is separable from the first water receiving tray 1 along the sliding direction of the second water receiving tray 2. The second water receiving tray 2 can be removed from the first water receiving tray 1 by sliding, which facilitates the disassembly and assembly of the second water receiving tray 2. After the second water receiving tray 2 is removed, the first water receiving tray 1 retains its original position and can continue to receive condensed water, which is highly practical.

[0062] A connecting structure 101 is disposed on the side wall of the first water receiving tray 1 . The connecting structure 101 is disposed to penetrate outwardly through at least one side wall of the first water receiving tray 1 . The second water receiving tray 2 is slidably connected to the connecting structure 101 .

[0063] It should be noted that if Figure 1 As shown, in the present specification, in order to more conveniently explain the technical solution of the present invention, the side walls of the first water receiving tray 1 and the second water receiving tray 2 are defined as quadrilateral structures, that is, the side walls of the first water receiving tray 1 and the second water receiving tray 2 are both set as four side walls, but the side walls of the water receiving tray structure may be more than four, or less than four, for example, the side walls of the first water receiving tray may include arc-shaped side walls, which can realize the functions of the present invention.

[0064] In this embodiment, the connecting structure 101 is at least arranged to penetrate the first side wall 111 outwardly, and the first side wall 111 is the side wall of the first water receiving tray 1 in the direction in which the second water receiving tray 2 slides out, that is, the side wall of the first water receiving tray 1 located in the positive direction of the X axis in the accompanying drawings. Here, when the side wall of the first water receiving tray 1 is not a quadrilateral structure, the first side wall 111 may include a plurality of side walls, so that the second water receiving tray 2 has sufficient sliding space, such as Figure 1As shown, the communication structure 101 can be configured as a first opening 1012. Figure 5 As shown, the connecting structure 101 can be set as a through hole 1011, which will not be described in detail here. In this way, the second water receiving tray 2 can slide out of the first water receiving tray 1 in a lateral sliding manner. It should be noted that in the above embodiment, lateral sliding only means that it is different from vertical sliding and is not limited to horizontal sliding. For example, in the accompanying drawings, the sliding direction of the second water receiving tray 2 has an angle with the X-axis direction.

[0065] It should be noted that the port on the connecting structure 101 into which the second water receiving tray 2 slides can be provided with a chamfered or rounded structure, and correspondingly, the edge on the second water receiving tray 2 can also be provided with a chamfered or rounded structure to facilitate the assembly of the second water receiving tray 2.

[0066] It should be noted that, during assembly, one end of the second water receiving tray 2 passes through the connecting structure 101 and is slidably connected to the first water receiving tray 1; in some other embodiments, the connecting structure 101 may only serve to avoid the second water receiving tray 2, and has no sliding connection with the second water receiving tray 2. For example, there are other structures on the first water receiving tray 1 that support and slide guide the second water receiving tray 2.

[0067] The advantage of this arrangement is that the connecting structure 101 is arranged to penetrate outwardly through at least one side wall of the first water receiving tray 1, and the second water receiving tray 2 can be disassembled and assembled by sliding and pulling horizontally. The water receiving tray structure occupies a small space, is easy to disassemble and clean, and is highly practical.

[0068] like Figure 1 and Figure 2 As shown, a first positioning surface structure 102 is provided on the first water receiving tray 1. The first positioning surface structure 102 is located on the side of the first water receiving tray 1 to which the sliding direction of the second water receiving tray 2 points. The first positioning surface structure 102 is used for positioning the second water receiving tray 2 in the sliding direction of the second water receiving tray 2.

[0069] like Figure 2As shown, the first positioning surface structure 102 is at least partially in contact with the side wall of the second water receiving tray 2. In some embodiments, the first positioning surface structure 102 is disposed on the side wall of the first water receiving tray 1 to which the second water receiving tray 2 slides in. For example, the water receiving tray 1 further includes a second side wall 112, and the second side wall 112 is the side wall of the first water receiving tray 1 to which the second water receiving tray 2 slides in, that is, the side wall of the first water receiving tray 1 in the opposite direction of the X-axis in the accompanying drawings, and the first positioning surface structure 102 is disposed on the second side wall 112; of course, the first positioning surface structure 102 can be directly the surface of the second side wall 112 close to the second water receiving tray 2, or it can be a surface processed on the second side wall 112.

[0070] It should be noted that the first positioning surface structure 102 can be completely fitted with the side wall of the second water receiving tray 2 to limit the position where the second water receiving tray 2 slides into on the first water receiving tray 1; as a further solution, the first positioning surface structure 102 can also partially fit with the side wall of the second water receiving tray 2, for example, the first positioning surface structure 102 is set to an inclined structure, and the first positioning surface structure 102 is inclined toward the side where the second water receiving tray 2 is located, for example, the first positioning surface structure 102 is an inclined plane, and the angle between the first positioning surface structure 102 and the bottom wall of the first water receiving tray 1 is an acute angle; of course, the first positioning surface structure 102 can also be a curved surface, which is no longer described in detail here. In this way, the first positioning surface structure 102 not only limits the position where the second water receiving tray 2 slides into, but also can further limit the second water receiving tray 2 from leaving the first water receiving tray 1 in a direction perpendicular to the sliding direction of the second water receiving tray 2.

[0071] The advantage of such a configuration is that one end of the second water receiving tray 2 passes through the connecting structure 101 and contacts the first positioning surface structure 102, thereby positioning the second water receiving tray 2 in the sliding direction of the second water receiving tray 2, which has high reliability and strong practicality.

[0072] It should be noted that, in some embodiments, the second water receiving tray 2 can continue to penetrate the second side wall 112. However, at this time, the position of the second water receiving tray 2 in the connecting structure 101 should be able to remain locked within a certain force range and will not slide out of the first water receiving tray 1 due to gravity or vibration under normal use.

[0073] like Figure 2As shown, a second positioning surface structure 103 is provided on the first water receiving tray 1, and the second positioning surface structure 103 is located on the first water receiving tray 1 in a direction perpendicular to the sliding direction of the second water receiving tray 2. The second positioning surface structure 103 is used for positioning the second water receiving tray 2 in a direction perpendicular to the sliding direction of the second water receiving tray 2.

[0074] like Figure 2 As shown, in some embodiments, the second positioning surface structure 103 is arranged on the left side wall of the connecting structure 101 on the first side wall 111, that is, on the side of the connecting structure 101 in the figure that is located opposite to the Y axis. In other embodiments, the second positioning surface structure 103 can also be arranged on the second side wall 112. In this case, the first positioning surface structure 102 and the second positioning surface structure 103 can form an angular structure to limit the second water receiving tray 2. The setting method of the second positioning surface structure 103 can be similar to the setting method of the first positioning surface structure 102, and will not be described in detail here.

[0075] In some embodiments, the second positioning surface structure 103 can be set to two, and the two second positioning surface structures 103 are respectively located on both sides of the connecting structure 101, that is, respectively located on both sides of the second water receiving tray 2; in some embodiments, the two second positioning surface structures 103 can not only form a limit for the second water receiving tray 2, but also cooperate with each other to form a sliding channel that is clamped with the second water receiving tray 2, and the two second positioning surface structures 103 can also be clamped with the second water receiving tray 2.

[0076] The advantage of such a setting is that the displacement of the second water receiving tray 2 in a direction perpendicular to the sliding direction of the second water receiving tray 2 is limited by the second positioning surface structure 103, thereby achieving reliable positioning of the second water receiving tray 2 in a direction perpendicular to the sliding direction of the second water receiving tray 2, and being able to guide the sliding of the second water receiving tray 2 to a certain extent, and the sliding stability of the second water receiving tray 2 is high and the practicability is strong.

[0077] like Figure 1 As shown, the first water receiving tray 1 includes a first water receiving tray body 11 and a support structure 12 . The support structure 12 is disposed at the bottom of the first water receiving tray body 11 , and the support structure 12 is used to support the second water receiving tray 2 .

[0078] It should be noted that the shape and position of the support structure 12 are not limited. The support structure 12 only needs to have a supporting function. The support structure 12 can be located inside the first water receiving tray body 11, the support structure 12 can also extend beyond the edge of the first water receiving tray body 11, and the support structure 12 can also be connected to the side wall of the first water receiving tray body 11.

[0079] The advantage of such a configuration is that, by providing the support structure 12, the support structure 12 forms a reliable support for the second water receiving tray 2, and the second water receiving tray 2 has high force stability and strong practicality.

[0080] At least one supporting structure 12 is provided, wherein at least one supporting structure 12 includes a step structure 121 , and the step structure 121 is used to limit the displacement of the second water receiving tray 2 .

[0081] like Figure 1 and Figure 6 As shown, in some embodiments, the step structure 121 includes a support platform 1201 and a limiting protrusion 1202, the support platform 1201 is connected to the limiting protrusion 1202, the limiting protrusion 1202 is protruded upward from the support platform 1201, and the limiting protrusion 1202 is in contact with the side wall of the second water receiving tray 2. The advantage of such a setting is that the support platform 1201 supports the second water receiving tray 2 from below, and the limiting protrusion 1202 limits the displacement of the second water receiving tray 2, which has high reliability and strong practicality.

[0082] It should be noted that, in some embodiments, the support structure 12 may include an installation groove structure (not shown in the figure). For example, a limit plate (not shown in the figure) is provided above the limit protrusion 1202, and the limit plate limits the second water receiving tray 2 from detaching from the support structure 12 in the up and down directions. That is to say, the installation groove structure is formed between the support platform 1201, the limit protrusion 1202 and the limit plate, and the second water receiving tray 2 is plugged or slidably connected to the installation groove structure.

[0083] It should be noted that, in some other embodiments, the step structure 121 may be arranged in such a manner that the step structure 121 includes a convex structure, a groove is arranged at the bottom of the second water receiving tray 2, and the limiting protrusion 1202 cooperates with the groove to limit the displacement of the second water receiving tray 2. For example, the groove is a slide groove structure arranged along the sliding direction of the second water receiving tray 2, and the limiting protrusion 1202 is at least partially accommodated in the groove. In this way, the step structure 121 can limit the displacement of the second water receiving tray 2 in the left and right directions.

[0084] It should be noted that, in the above embodiment, the step structure 121 can be set to be multiple, and the step structures 121 respectively limit the displacement of the second water receiving tray 2 along different directions; and the first positioning surface structure 102 or the second positioning surface structure 103 can be set on the limiting protrusion 1202; the supporting structure 12 can also be set on the side wall of the first water receiving tray body 11, which is not described in detail here.

[0085] The advantage of such a configuration is that at least one of the support structures 12 includes a step structure 121, and the step structure 121 is used to limit the displacement of the second water receiving tray 2. The support structure 12 can not only support the second water receiving tray 2, but also limit the displacement of the second water receiving tray 2 to a certain extent. The installation structure of the second water receiving tray 2 is reliable and practical.

[0086] The support structure 12 includes at least two step structures 121 , and the two step structures 121 are symmetrically arranged. The step structures 121 are used to limit the displacement of the second water receiving tray 2 .

[0087] It should be noted that if Figure 6 As shown, in some embodiments, the support platform 1201 is a long strip structure arranged along the Y-axis direction in the accompanying drawings, and the two limiting protrusions 1202 are respectively located at the two ends of the length direction of the support platform 1201, that is, at the two ends along the Y-axis direction, and the two limiting protrusions 1202 are respectively fitted with the two sides of the second water receiving tray 2; in other embodiments, the support platform 1201 is a long strip structure arranged along the sliding direction of the second water receiving tray 2, that is, a long strip structure arranged along the X-axis direction in the accompanying drawings, and the two limiting protrusions 1202 are respectively arranged on the two support platforms 1201, and the two limiting protrusions 1202 are respectively fitted with the two sides of the second water receiving tray 2. At this time, a sliding channel for the second water receiving tray 2 is formed between the two step structures 121.

[0088] The advantage of such a configuration is that the two step structures 121 are symmetrically arranged, and the step structures 121 are used to limit the displacement of the second water receiving tray 2. The two step structures 121 cooperate to limit the displacement of the second water receiving tray 2, and can also form a sliding channel for the second water receiving tray 2 to a certain extent, and guide the second water receiving tray 2 for sliding. The second water receiving tray 2 is reliably limited and has high stability.

[0089] In some embodiments, the second water receiving pan 2 is disposed below the evaporator 3 of the air conditioner, and the second water receiving pan 2 is used to filter the condensed water flowing down from the evaporator 3. The advantage of such a configuration is that the condensed water flowing down from the evaporator 3 is first filtered through the second water receiving pan 2 to filter out large particles and debris in the condensed water, thereby reducing the probability of clogging of the first water receiving pan 1 and achieving high reliability.

[0090] like Figures 1 to 3 As shown, the second water receiving tray 2 includes a second water receiving tray body 21 and a water retaining structure 22 , and the water retaining structure 22 is disposed at the bottom of the second water receiving tray body 21 .

[0091] It should be noted that the water retaining structure 22 is integrally connected or detachably connected to the bottom wall of the second water receiving tray body 21. The integral connection, such as injection molding, has the advantage of convenient molding and small processing amount. The detachable connection, such as direct placement, magnetic installation, etc., has the advantage of convenient disassembly, replacement and cleaning.

[0092] It should be noted that the water retaining structure 22 may be a structure that can form a certain barrier and buffer to the flow of condensed water, and the shape and position of the water retaining structure 22 are not limited. For example, the water retaining structure 22 may be set as a water retaining rib, and the position, structure and number of the water retaining rib are not limited. For example, Figure 7 As shown, the water retaining structure 22 includes a first water retaining rib 221 and a second water retaining rib 222. The second water retaining rib 222 can be arranged along the left and right direction of the second water receiving tray body 21, that is, along the Y-axis direction in the accompanying drawing, and the first water retaining rib 221 can be arranged along the front and rear direction of the second water receiving tray body 21, that is, along the X-axis direction in the accompanying drawing.

[0093] The advantage of such a configuration is that, by providing the water retaining structure 22 on the bottom wall of the second water receiving tray body 21, the condensed water received by the second water receiving tray 2 can be buffered and blocked from slowing down by the water retaining structure 22, so that large particles and debris in the condensed water are deposited, thereby reducing the probability of blockage of the water receiving tray structure and achieving high reliability.

[0094] The water retaining structure 22 is a water retaining rib. In this way, the water retaining structure 22 is set as a water retaining rib, and the condensed water is buffered and decelerated by the water retaining rib, so that larger particles and debris are deposited, and the structure is simple and practical.

[0095] The number of the water retaining structures 22 is at least two, wherein at least two of the water retaining structures 22 are staggered.

[0096] like Figure 8As shown, in some embodiments, at least one of the water retaining structures 22 is a first water retaining rib 221, and the two ends of the first water retaining rib 221 are respectively connected to the two side walls of the second water receiving tray body 21, for example, the two side walls in the X-axis direction. In this way, the water retaining structure 22 completely retains water, and the condensed water flows out by overflowing the water retaining structure 22, with a simple structure and strong practicality.

[0097] In some embodiments, at least two first water retaining ribs 221 are provided, wherein the heights of at least two first water retaining ribs 221 are inconsistent. Here, the height direction refers to the Z-axis direction in the drawings. Thus, by setting the heights of the first water retaining ribs 221 to be different, a height difference is formed, which has a better buffering effect on condensed water, and large particles or debris are blocked between the first water retaining ribs 221.

[0098] like Fig. 9 As shown, in some embodiments, at least two of the water retaining structures 22 are first water retaining ribs 221 , and the first water retaining ribs 221 are provided with third openings 2211 , and the third openings 2211 of two adjacent first water retaining ribs 221 are staggered.

[0099] It should be noted that the bottom wall of the third opening 2211 may coincide with the bottom wall of the second water receiving tray body 21 , or may be higher than the bottom wall of the second water receiving tray body 21 , which is not a limitation.

[0100] The advantage of such an arrangement is that at least two of the water retaining structures 22 are arranged in a staggered manner, and through the staggered arrangement, condensed water is blocked at different positions, so that the flow direction of the condensed water is changed, the buffering and blocking effect is good, and the reliability is high.

[0101] It should be noted that in the above embodiment, the second water receiving tray 2 includes a second water receiving tray body 21 , and the second water receiving tray body 21 is provided with at least one drain port. The first water receiving tray 1 can receive condensed water discharged from the second water receiving tray 2 .

[0102] In some embodiments, a second opening 201 is provided at one end of the second water receiving tray body 21, and the second opening 201 is located on the side wall or the bottom of the second water receiving tray body 21. For example, the second opening 201 covers part or all of one of the side walls of the second water receiving tray body 21. In other words, the second opening 201 is the drain port. For example, the bottom of the second opening 201 coincides with the bottom wall of the second water receiving tray body 21.

[0103] The advantage of this arrangement is that a second opening 201 is provided at one end of the second water receiving tray body 21, and condensed water flows out from the second opening 201. Compared with a traditional drain outlet, the second opening 201 is not easily blocked, has a simple structure, and is highly practical.

[0104] It should be noted that in the above embodiment, the water retaining structure 22 can be arranged on the end of the second water receiving tray body 21 close to the drain outlet, such as the end close to the second opening 201. In this way, the water retaining structure 22 has a better water retaining effect.

[0105] A filter screen 23 is disposed in the second water receiving tray 2 . The filter screen 23 at least partially covers the bottom of the second water receiving tray body 21 . The filter screen 23 is used to filter water flowing toward the first water receiving tray 1 .

[0106] like Figure 4 and Figure 5 As shown, in some embodiments, the filter net 23 can be installed inside the second water receiving tray body 21. At this time, the bottom wall of the second water receiving tray body 21 can be selected as a structure that penetrates from top to bottom as needed, that is, penetrates along the Z-axis direction; in some other embodiments, the filter net 23 can be installed on the water retaining structure 22, for example, the filter net 23 is connected to the water retaining rib; for example, the filter net 23 is integrally arranged with the water retaining rib, and the second water receiving tray body 21 is detachably connected to the water retaining rib; for example, the second water receiving tray body 21 is provided with a mounting groove for mounting the water retaining rib. In this way, it can play multiple functions of filtering, buffering and sedimentation. Of course, the filtering level of the filter net 23, or the size of the mesh of the filter net, can be determined according to the impurities to be filtered out or the filtering requirements.

[0107] The advantage of such a configuration is that, by providing the filter net 23, the condensed water received by the second water receiving tray 2 is filtered before flowing out, the first water receiving tray 1 is less likely to be blocked, and the cleaning frequency of the water receiving tray structure is lower.

[0108] In the above embodiment, a hand-pull portion (not shown in the figure) is provided on the second water receiving tray 2, and the hand-pull portion is exposed on the first water receiving tray 1. It should be noted that the hand-pull portion is used for hand-gripping, and the hand-pull portion can be a handle provided on the second water receiving tray 2, or a convex strip provided on the second water receiving tray 2; the position and structure of the hand-pull portion can be determined according to the installation method and specific structure of the second water receiving tray 2. The advantage of such a setting is that the hand-pull portion is provided, and the removal, placement and disassembly of the second water receiving tray 2 are more convenient and practical. In other words, the hand-pull portion is located at one end of the second water receiving tray 2 away from the first water receiving tray. When the second water receiving tray 2 is installed on the first water receiving tray 1, the hand-pull portion is located outside the first water receiving tray 1, which is convenient for hand-gripping and plugging.

[0109] The advantage of such an arrangement is that the hand-pull portion is easy to plug and unplug, and condensed water is not likely to cause contamination of the hand-pull portion, which is convenient, reliable and highly practical.

[0110] Another embodiment of the present invention provides an air conditioner, such as a duct air conditioner, comprising any of the above-mentioned water receiving tray structures. The duct air conditioner has all the advantages of the water receiving tray, which will not be described in detail here.

[0111] The water receiving tray structure is used to be arranged below the evaporator 3 of the air duct machine, and the second water receiving tray 2 of the water receiving tray structure can slide out relative to the first water receiving tray 1 of the water receiving tray structure.

[0112] like Fig.10 As shown, the duct machine also includes an evaporator 3 and a volute assembly 4. The position of the water receiving tray structure corresponds to the position of the evaporator 3. The air outlet of the volute assembly 4 blows toward the evaporator 3. The second water receiving tray of the water receiving tray structure is slidably connected to the first water receiving tray, and the direction in which the second water receiving tray slides out of the first water receiving tray points to the side where the volute assembly 4 is located.

[0113] It should be noted that the side of the duct unit where the volute assembly 4 is located is the location of the return air outlet, and the water receiving pan structure is usually disassembled, assembled, cleaned, etc. from the side where the volute assembly 4 is located. When disassembling, assembling, cleaning, etc. the water receiving pan structure, some devices may need to be removed, such as the volute assembly 4 or the partition 5; of course, as an embodiment thereof, the partition 5 or the volute assembly 4 may be provided with a avoidance structure for the second water receiving pan 2, or, in the assembled state, one end of the second water receiving pan 2 away from the first water receiving pan 1 is exposed on the partition 5, which will not be described in detail here.

[0114] The advantage of such an arrangement is that the water receiving tray structure is used to be arranged below the evaporator 3 of the duct air conditioner, and the second water receiving tray 2 of the water receiving tray structure can slide out relative to the first water receiving tray 1 of the water receiving tray structure. When the water receiving tray structure is cleaned, the first water receiving tray 1 does not need to be disassembled, and the second water receiving tray 2 can be pulled out by sliding. The required disassembly and assembly space is small, the reliability is high, and the practicality is strong.

[0115] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
