Description

Technical Field

[0001] The present invention relates to the technical field of air duct machines, and more particularly, to a water receiving tray and an air duct machine. Background Art

[0002] An air duct machine is provided with a water receiving tray which has a drain nozzle for discharging the accumulated water in the water receiving tray. In the prior art, the drain nozzle protrudes outward from the side surface of the water receiving tray and extends outwards through a notch on the machine shell. When the water receiving tray needs to be moved, the machine shell will interfere with the drain nozzle, resulting in the inability to freely move the water receiving tray. Summary of the Invention

[0003] The problem solved by the present invention is that in the prior art, the drain nozzle protrudes outward from the end face of the water receiving tray and extends outwards through a notch on the machine shell, and during the process of pulling out the water receiving tray outward, the machine shell of the air duct machine interferes with the drain nozzle.

[0004] To solve the above problems, the present invention provides a water receiving tray which is disposed inside an air duct machine. The water receiving tray includes a water receiving tray body and a drainage structure. The drainage structure can be hidden inside the air duct machine, and the water receiving tray body is communicated with the drainage structure.

[0005] Thus, the drainage structure can be hidden inside the air duct machine, so that during the process of moving and pulling out the water receiving tray, the drainage structure will not interfere with the machine shell of the air duct machine, facilitating the smooth pulling out of the water receiving tray, and the water in the water channel inside the water receiving tray is discharged outwards through the drainage structure.

[0006] Optionally, the drainage structure includes a drain nozzle, and an avoidance structure is arranged on the side surface of the water receiving tray body, and the drain nozzle can be hidden and arranged inside the avoidance structure.

[0007] Thus, by arranging the avoidance structure on the side surface of the water receiving tray body, the drain nozzle can be hidden and arranged inside the avoidance structure, so that when the water receiving tray is pulled out, the machine shell of the air duct machine will not interfere with the drain nozzle hidden inside the avoidance structure, ensuring the smooth pulling out of the water receiving tray.

[0008] Optionally, the avoidance structure is a groove structure arranged on the side surface of the water receiving tray body.

[0009] Thus, by arranging the avoidance structure on the side surface of the water receiving tray body, the avoidance structure is a groove structure, and the drain nozzle can be hidden and arranged inside the groove structure, so that during the process of moving and pulling out the water receiving tray, the machine shell of the air duct machine will not interfere with the drain nozzle hidden inside the avoidance structure, facilitating the smooth pulling out of the water receiving tray.

[0010] Optionally, a water leakage prevention cover plate is arranged on the upper part of the avoidance structure.

[0011] Thus, since the drain nozzle can be hidden in the avoidance structure, a leak-proof cover plate is provided on the upper part of the avoidance structure to block the drain nozzle and prevent water leakage.

[0012] Optionally, the distance between the drain nozzle and the end face of the water receiving tray body is not less than 1 mm.

[0013] Thus, the distance between the end of the drain nozzle and the side face of the water receiving tray body is greater than or equal to 1 mm, that is, the drain nozzle does not protrude beyond the end face of the water receiving tray body, so that when the water receiving tray is pulled out, the casing of the air duct machine will not interfere with the drain nozzle, facilitating the smooth pulling out of the water receiving tray.

[0014] Optionally, the drain nozzle is integrally connected or detachably connected to the avoidance structure.

[0015] Thus, the drain nozzle is integrally connected or detachably connected to the avoidance structure, that is, the drain nozzle can be hidden in the avoidance structure and does not protrude beyond the end face of the water receiving tray body, preventing the casing of the air duct machine from interfering with the pulling out of the water receiving tray and facilitating the smooth pulling out of the water receiving tray.

[0016] Optionally, the drain nozzle includes a telescopic tube that can be telescopic relative to the avoidance structure.

[0017] Thus, the telescopic tube can be extended or shortened relative to the avoidance structure, so that the telescopic tube is hidden in the avoidance structure, facilitating the smooth pulling out of the water receiving tray.

[0018] Optionally, the telescopic tube has an extended position extending beyond the end face of the water receiving tray body and a contracted position retracted into the avoidance structure.

[0019] Thus, when the air duct machine is in the working state, the telescopic tube extends and protrudes beyond the end faces of the avoidance structure and the water receiving tray body for normal drainage; when the water receiving tray is taken out, the telescopic tube is compressed to retract it into the avoidance structure of the water receiving tray body to avoid the casing of the air duct machine interfering with the pulling out of the water receiving tray.

[0020] Optionally, the drainage structure is provided on the bottom, front side plate or rear side plate of the water receiving tray body.

[0021] Thus, the drainage structure can be provided on the bottom of the water receiving tray body, or on the front side plate or rear side plate of the water receiving tray body, and the drainage structure is communicated with the water channel in the water receiving tray body, so that the casing of the air duct machine does not interfere with the drainage structure when the water receiving tray is pulled outwards.

[0022] Optionally, a sealing cover for preventing air leakage is provided on the drainage structure.

[0023] Thus, the sealing cover is arranged between the drain nozzle and the housing of the air duct machine to prevent air leakage at the connection part between the drainage structure and the housing.

[0024] Optionally, the present invention further provides an air duct machine, including the water receiving tray described in any one of the above. The beneficial effects of the air duct machine are the same as those of the water receiving tray, and will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] It should be noted that in the coordinate system XYZ provided in this article, the positive direction of the X-axis represents the right side, the negative direction of the X-axis represents the left side, the positive direction of the Y-axis represents the rear, the negative direction of the Y-axis represents the front, the positive direction of the Z-axis represents the upper side, and the negative direction of the Z-axis represents the lower side; and the directions or positional relationships indicated by terms such as "upper" and "lower" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "set", and "connected" 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 directly connected, or indirectly connected through an intermediate medium; the term "adaptively connected" should be understood in a broad sense and can be a plug connection, a socket connection, or a threaded connection; for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] At the same time, it should be noted that the terms "first", "second", etc. in the specification, claims, and above-mentioned drawings of the present invention are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0038] The current air duct machines, such as Figure 1As shown in the figure, the air duct machine includes a middle partition 1. The upper part of the middle partition is provided with a top plate 13. The middle partition 1 divides the interior of the air duct machine into a heat exchange chamber and a return air chamber. An evaporator 12 is arranged inside the heat exchange chamber. The lower part of the air duct machine where the evaporator 12 is located is the first bottom plate 6. A water receiving tray body 2 is arranged on the upper part of the first bottom plate 6. The left and right ends of the evaporator 12 are respectively installed on the left side plate 7 and the right side plate 8 of the air duct machine. An electric control box 9 is arranged on one side of the middle partition 1 close to the return air chamber. A volute assembly 10 is arranged on the side of the middle partition 1 located in the return air chamber, and the volute assembly 10 is opposite to the position of the evaporator 12. The lower part of the air duct machine where the volute assembly 10 is located is the second bottom plate 11. A return air opening is arranged in the return air chamber. Since the water receiving tray body 2 is arranged below the evaporator 12 and is used to receive the condensed water generated by the evaporator 12, there will be some accumulated water, bacteria and impurities in the water receiving tray body 2, which need to be cleaned regularly. The water receiving tray body 2 is provided with a drain nozzle 4. A notch is opened on the housing of the air duct machine, that is, on the left side plate 7 of the air duct machine, so that the drain nozzle 4 can extend outwards. The drain nozzle 4 protrudes out of the side of the water receiving tray body 2 and extends outwards from the notch on the housing. When the water receiving tray body 2 needs to be moved and pulled out, the housing of the air duct machine will interfere with the drain nozzle 4, resulting in the water receiving tray body 2 being unable to move freely.

[0039] As Figure 2 and Figure 3 shown, the present invention provides a water receiving tray, which includes a water receiving tray body 2 and a drainage structure. The drainage structure can be hidden inside the air duct machine, and the water channel inside the water receiving tray body 2 is communicated with the drainage structure.

[0040] In one embodiment of the present invention, the drainage structure extends beyond the side of the water receiving tray body, but the drainage structure can be hidden inside the air duct machine. At this time, the drainage structure is the drain nozzle 4. At this time, the sum of the lengths of the drainage structure and the water receiving tray body is less than or equal to the length of the air duct machine, that is, it does not exceed the housing of the air duct machine.

[0041] The advantage of such a setting is that when the water receiving tray is pulled out, since the drainage structure is inside the air duct machine, the housing of the air duct machine will not interfere with the pulling out of the water receiving tray, ensuring that the water receiving tray can be pulled out smoothly.

[0042] In another embodiment of the present invention, the drainage structure is arranged on the bottom, front side plate or rear side plate of the water receiving tray body. The side of the water receiving tray body close to the middle partition is the front side plate of the water receiving tray, and the side of the water receiving tray body far from the middle partition is the rear side plate of the water receiving tray. The front side plate and the rear side plate of the water receiving tray are arranged opposite to each other and are parallel to the middle partition.

[0043] It should be noted that when the drainage structure is a drain outlet, the drain outlet can be arranged on the bottom, the front side plate or the rear side plate of the water receiving tray body. The drain outlet is communicated with the water channel in the water receiving tray. In order to drain the water in the water receiving tray, an external water outlet pipe is communicated with the drain outlet, so as to effectively drain the water in the water receiving tray. Before taking out the water receiving tray, the water outlet pipe is pulled out from the drain outlet, so that the casing of the air duct machine will not interfere with the extraction of the water receiving tray.

[0044] In an embodiment of the present invention, when the drainage structure is a drain nozzle 4, the drain nozzle 4 can be arranged on the bottom, the front side plate or the rear side plate of the water receiving tray body, and the drain nozzle 4 does not protrude beyond the casing of the air duct machine. Of course, in order to drain the water in the water channel in the water receiving tray out of the water receiving tray, an external water outlet pipe is communicated with the drain nozzle 4, so as to effectively drain the water in the water receiving tray out of the air duct machine. Among them, when the drain nozzle 4 is arranged at the bottom of the water receiving tray, in order to prevent the water receiving tray body from pressing and damaging the drain nozzle 4, a groove can be opened at the bottom of the water receiving tray body, and the groove is matched with the diameter of the drain nozzle 4 or the drain rod. Before taking out the water receiving tray, the water outlet pipe is removed from the drain pipe, so that the casing of the air duct machine will not interfere with the extraction of the water receiving tray.

[0045] In an embodiment of the present invention, the drainage structure includes a drain nozzle 4, and an avoidance structure 3 is arranged on the side surface of the water receiving tray body, and the drain nozzle 4 can be hidden in the avoidance structure 3.

[0046] It should be noted that the drain nozzle 4 can be hidden in the avoidance structure on the side surface of the water receiving tray body, that is, the end of the drain nozzle 4 can be flush with the side surface or the side plate of the water receiving tray. The advantage of such a setting is that the casing of the air duct machine will not interfere with the extraction of the water receiving tray, and the water receiving tray can be smoothly extracted.

[0047] In an embodiment of the present invention, the avoidance structure 3 is a groove structure arranged on the end face of the water receiving tray body 2.

[0048] It should be noted that, that is, an avoidance structure 3 is arranged on one side of the end face of the water receiving tray body 2. The avoidance structure is a groove structure arranged on the end face of the water receiving tray structure, and the end face of the avoidance structure 3 coincides with the end face of the water receiving tray body 2. The advantage of such a setting is that not only the size of the water receiving tray body 2 is reduced, but also the casing of the air duct machine is effectively prevented from interfering with the drain nozzle 4 hidden in the avoidance structure 3. In this embodiment, the avoidance structure 3 can be, for example Figure 2The fan-shaped groove structure shown, that is, the cross-section obtained by cutting the avoidance structure 3 parallel to the Y-axis in the coordinate system is a fan-shaped structure; the avoidance structure 3 can also be a rectangular groove structure, and the rectangular groove structure is parallel to the end face of the water receiving tray body 2.

[0049] In an embodiment of the present invention, a water leakage prevention cover plate is provided on the upper part of the avoidance structure.

[0050] It should be noted that the avoidance structure is arranged on the side of the water receiving tray body, and a water leakage prevention cover plate is provided on the upper part of the avoidance structure to prevent the condensed water from falling outside the water receiving tray body, playing a waterproof role.

[0051] In the above embodiment of the present invention, the upper surface of the water leakage prevention cover plate is an inclined plane, and the water leakage prevention cover plate inclines towards the inside of the water receiving tray body, so that the condensed water can automatically flow into the water receiving tray body along the inclined plane.

[0052] In the above embodiment of the present invention, the upper surface of the water leakage prevention cover plate is an arc-shaped plane, and the arc-shaped plane is recessed downward, and the arc-shaped plane inclines towards the inside of the water receiving tray body; the advantage of such a setting is that the condensed water generated by the evaporator will automatically flow along the arc-shaped plane towards the inside of the water receiving tray body, and the water leakage prevention cover plate plays a role in automatically collecting the condensed water and guiding it into the water receiving tray body to prevent water leakage.

[0053] In an embodiment of the present invention, the drain nozzle 4 is integrally connected or detachably connected to the avoidance structure 3.

[0054] It should be noted that in this embodiment, the drain nozzle 4 is integrally connected to the avoidance structure 3, that is, when manufacturing the water receiving tray body, the drain nozzle 4 is directly integrally arranged in the groove structure on the end face of the water receiving tray body. The advantage of such a setting is that there is no need to additionally add a new drain nozzle 4; for another example, the drain nozzle is detachably connected to the avoidance structure, that is, a drain hole is provided on the end face or side of the water receiving tray body, and the drain hole is communicated with the water channel in the water receiving tray body. The drain nozzle 4 can be embedded in the drain hole, and the drain nozzle 4 is detachably connected to the drain hole, that is, the two can be detachably connected in ways such as socket connection, plug connection or threaded connection, so that the water in the water receiving tray body 2 is discharged outwards from the drain nozzle 4 through the drain hole in sequence.

[0055] In an embodiment of the present invention, as Figure 3 shown, the distance A between the drain nozzle 4 and the side of the water receiving tray body 2 is not less than 1 mm.

[0056] It should be noted that the distance between the end of the drain nozzle 4 and the side surface of the water receiving tray body is greater than or equal to 1 mm, and the end of the drain nozzle 4 does not exceed or protrude from the end surface of the water receiving tray body 2. The advantage of this setting is that it effectively prevents the drain nozzle 4 from interfering with the extraction of the water receiving tray, facilitating the smooth extraction of the water receiving tray.

[0057] In an embodiment of the present invention, the drain nozzle 4 includes a telescopic tube that can be telescoped relative to the avoidance structure 3.

[0058] It should be noted that the position of the end of the telescopic tube relative to the avoidance structure 3 can be manually adjusted and changed; the telescopic tube has an extended position extending from the end surface of the water receiving tray body 2 and a contracted position retracted into the avoidance structure 3; that is, when the air duct machine is in a working state, the telescopic tube is stretched and extended so that it extends out of the avoidance structure 3 and the end surface of the water receiving tray body 2, and the telescopic tube can also extend outwards from the notch of the casing of the air duct machine for normal drainage operation; when it is necessary to take out the water receiving tray body 2 for cleaning, the telescopic tube is compressed to contract it into the avoidance structure 3 to avoid the casing of the air duct machine interfering with the extraction of the water receiving tray body 2.

[0059] In an embodiment of the present invention, the telescopic tube can be in the form of Figure 4 the threaded connection shown; it should be noted that the telescopic tube is a sleeve, that is, the telescopic tube is threadedly connected to the drain hole provided on the side surface of the water receiving tray body 2. External threads are preset on the outside of the telescopic tube, and the drain hole is adapted to the telescopic tube. By rotating the number of turns of the telescopic tube, the distance between the end of the telescopic tube and the end surface of the water receiving tray body 2 is changed, thereby preventing the telescopic tube from interfering with the extraction of the water receiving tray body 2.

[0060] Different from the above embodiment, as Figure 5 shown, the telescopic tube can be a telescopic hose, such as a rubber telescopic hose, that is, one end of the telescopic tube is sleeved or screwed to the drain hole opened on the side surface of the water receiving tray body 2, and the end position of the telescopic tube is adjusted by manual stretching or compression, so that when the water receiving tray body 2 is taken out, the telescopic tube is compressed into the avoidance structure 3, effectively avoiding the casing of the air duct machine interfering with the extension of the water receiving tray body 2.

[0061] In an embodiment of the present invention, as Figure 6 and Figure 7As shown, a sealing cover 5 for preventing air leakage is further provided on the drain nozzle 4; it should be noted that the sealing cover 5 is arranged between the drain nozzle 4 and the housing of the air duct machine to prevent air leakage; wherein, the sealing cover 5 can be fixedly installed at a position corresponding to the drain nozzle 4 in the housing by bolts, and the inner wall of the sealing cover 5 is in close contact with the outer wall of the drain nozzle 4, thereby preventing air leakage at the part between the drain nozzle 4 and the drain port.

[0062] An embodiment of the present invention further provides an air duct machine, including the water receiving tray described above arbitrarily, and the water receiving tray body of the water receiving tray is arranged in the air duct machine; the beneficial effects of the air duct machine are the same as those of the water receiving tray, and will not be elaborated here.

[0063] 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 should be subject to the scope defined by the claims.
