Description

Technical Field

[0001] The present invention relates to the technical field of air duct machines, and in particular to an air duct machine. Background Art

[0002] The duct unit is a concealed air conditioner installed inside the ceiling. The duct unit includes a housing, a fan component, a heat exchange component, a water receiving component, a filter component, etc. The internal components of the duct unit are inconvenient to disassemble after assembly, and it is not easy to clean the inside. For example, the water receiving pan is set below the evaporator to collect the condensed water produced by the evaporator. There will be some accumulated water, bacteria, and impurities in the water receiving pan. However, in the prior art, since the lowest part of the evaporator is lower than the edge of the water receiving pan, the bottom of the evaporator is against the upper surface of the water receiving pan, and the water receiving pan cannot be dragged and separated from the evaporator. In addition, if the middle partition is not removed, the water receiving pan cannot be removed from the return air port through the middle partition, and the water receiving pan is inconvenient to disassemble and assemble, and thus cannot be cleaned regularly. Summary of the invention

[0003] The problem solved by the invention is that the lower end of the evaporator in the existing duct machine abuts against the upper part of the water receiving pan, so that the water receiving pan cannot be drawn out from the return air port for cleaning alone, and the accumulated water, bacteria, impurities, etc. in the water receiving pan cannot be cleaned regularly.

[0004] In order to solve the above problems, the present invention provides a duct air conditioner, the duct air conditioner comprises

[0005] A heat exchange chamber, an evaporator, a water receiving tray and a middle partition, wherein the evaporator is arranged inside the heat exchange chamber, the water receiving tray is arranged below the evaporator, and the lower part of the middle partition is preset with a notch for withdrawing and making way for the water receiving tray, wherein the water receiving tray can be driven by external force to move horizontally relative to the evaporator.

[0006] Therefore, when the water receiving tray needs to be cleaned, the water receiving tray can be pulled by external force to move horizontally relative to the evaporator, and removed from the return air port of the duct machine through the gap opened on the middle partition.

[0007] Optionally, a sealing rib is provided on the upper portion of the water receiving tray, and the sealing rib contacts and seals with the lower portion of the evaporator.

[0008] As a result, the sealing rib on the upper part of the water receiving tray contacts and seals with the lower part of the evaporator, effectively preventing the airflow from being blown out directly from the air outlet without passing through the evaporator.

[0009] Optionally, a height b of the sealing rib is greater than or equal to an edge height c of the water receiving tray.

[0010] Therefore, the height b of the sealing rib is greater than or equal to the edge height c of the water receiving tray, so that the upper part of the sealing rib is completely in contact and sealed with the lower part of the evaporator, effectively preventing the airflow from being blown out directly from the air outlet without passing through the evaporator.

[0011] Optionally, the width a of the notch is greater than or equal to the height b of the sealing rib.

[0012] Therefore, the height b of the sealing rib is greater than or equal to the edge height c of the water receiving tray, and the width a of the notch is greater than or equal to the height b of the sealing rib, so the water receiving tray can be moved from the notch under the middle partition toward the return air outlet to facilitate the withdrawal of the return air outlet.

[0013] Optionally, a supporting protrusion is provided on the upper part of the water receiving tray (2), and the supporting protrusion is in contact with the lower part of the evaporator.

[0014] Thus, the supporting protrusion lifts up the lower part of the evaporator, so that the lower part of the evaporator does not abut against the water receiving tray, thereby facilitating that the water receiving tray can be easily and horizontally drawn out from the notch of the middle partition.

[0015] Optionally, a pull-up assembly for raising the lower part of the evaporator is provided in the heat exchange chamber, one end of the pull-up assembly is connected to the top plate of the air duct machine or the side plate of the air duct machine, and the other end of the pull-up assembly is connected to the lower part of the evaporator.

[0016] Thus, the lower part of the evaporator is pulled up by the pulling assembly installed on the top plate and the side plate of the air duct unit, so that the evaporator is separated from the water receiving tray, thereby facilitating the water receiving tray to be pulled out of the notch.

[0017] Optionally, a pull-up assembly for raising the lower part of the evaporator is provided in the heat exchange chamber, one end of the pull-up assembly is connected to the middle partition plate, and the other end of the pull-up assembly is connected to the lower part of the evaporator.

[0018] Thus, the pulling assembly installed on the middle partition pulls up the lower part of the evaporator to separate the evaporator from the water receiving tray, that is, the lower part of the evaporator does not abut against the upper part of the water receiving tray, so that the water receiving tray can be moved and pulled out from the notch.

[0019] Optionally, the pulling assembly includes a pulling rod.

[0020] Thus, the lower part of the evaporator is pulled up by the pull rod, so that the lower part of the evaporator is separated from the water receiving tray, thereby preventing the evaporator from interfering with the extraction of the water receiving tray.

[0021] Optionally, the pulling assembly includes a driving unit and a telescopic rod, the driving unit is connected to one end of the telescopic rod, the other end of the telescopic rod is connected to the lower part of the evaporator, and the driving unit drives the telescopic rod to extend and retract to drive the lower part of the evaporator to rise and fall.

[0022] Therefore, when the duct air conditioner is in working mode, the driving unit does not work, the telescopic rod is in an extended or stretched state, and the lower part of the evaporator is against the upper part of the water receiving tray; when the duct air conditioner is in cleaning mode, the driving unit drives the lower part of the evaporator to rise to a set height, so that the evaporator is separated from the water receiving tray, thereby facilitating the water receiving tray to be moved and withdrawn from the notch toward the return air port, thereby realizing the cleaning operation of the water receiving tray; since the driving unit only works when cleaning the water receiving tray, the power loss is reduced.

[0023] Optionally, the duct air conditioner further comprises a return air outlet side plate, and the return air outlet side plate is provided with an opening for the water receiving tray to be drawn out and avoided.

[0024] Therefore, the return air port is arranged on the return air port side plate, and an opening is opened on the return air port side plate. When the water receiving tray is pulled out, it first passes through the notch of the middle partition plate and is finally pulled out from the opening of the return air port side plate.

[0035] Duct machines in related technologies such as Figure 1 As shown, the duct machine includes a middle partition 1, which divides the interior of the duct machine into a heat exchange chamber and a return air chamber. An evaporator 4 is arranged inside the heat exchange chamber. A first bottom plate 10 is located below the evaporator 4 in the duct machine. A water receiving pan 2 is arranged on the top of the first bottom plate 10. The left and right ends of the evaporator 4 are respectively installed on the left side plate 8 and the right side plate 9 of the duct machine. On the side of the middle partition 1 close to the return air chamber, an electric control box 13 is arranged; a volute assembly 12 is arranged on the middle partition 1 on the return air chamber side, and the volute assembly 12 is opposite to the position of the evaporator 4, and the lower part of the volute assembly 12 in the duct machine is a second bottom plate 11, and a return air port is arranged in the return air chamber; since the water receiving pan 2 is arranged below the evaporator 4 and is used to hold the condensed water generated by the evaporator 4, there will be some accumulated water, bacteria and impurities in the water receiving pan 2, which needs to be cleaned regularly, but the lowest end of the evaporator 4 is against the upper edge of the water receiving pan 2, so that the water receiving pan 2 cannot be dragged and separated from the evaporator 4, and when the middle partition is not removed, the water receiving pan 2 cannot pass through the middle partition and be removed from the return air port; in order to solve the above technical problems, the present invention relates to a duct machine, and the water receiving pan 2 can move horizontally relative to the evaporator 4 so as to be removed from the return air port.

[0036] like Figure 2As shown, the water receiving tray 2 provided by the present invention is arranged on the first bottom plate 10, and is used to store the condensed water generated by the evaporator 4, that is, the evaporator 4 is arranged above the water receiving tray 2; the water receiving tray 2 can move horizontally relative to the evaporator 4 under the action of external force, and a gap is opened in the lower part of the middle partition. When the water receiving tray is pulled out, the water receiving tray is moved through the gap 5 opened on the middle partition so as to be pulled out from the return air outlet, that is, the moving direction of the water receiving tray 2 is the same as the positive direction of the Y-axis in the coordinate system.

[0037] It should be noted that in order to avoid the lower part of the evaporator from abutting against the upper part of the water receiving tray and facilitate the smooth withdrawal of the water receiving tray, a variety of implementation methods can be adopted.

[0038] In one embodiment of the present invention, if the lower mounting position of the evaporator is raised, since the left and right ends of the evaporator are correspondingly mounted on the left and right panels in the duct machine, a plurality of mounting holes can be added to the left and right panels, and the lower portion of the evaporator is mounted on the left and right panels at a fixed position by manually adjusting the lower portion of the evaporator, that is, the lower portion of the evaporator is raised, and bolts are inserted into the additional mounting holes, thereby raising the lower position of the evaporator, separating the evaporator from the water receiving pan, thereby facilitating the smooth withdrawal of the water receiving pan from the return air outlet; the mounting holes can be waist-shaped holes or rectangular holes, and can also be multiple circular holes arranged vertically, which will not be described in detail here.

[0039] For another example, the installation position of the water receiving pan can be lowered so that the lower part of the evaporator does not abut against the water receiving pan; that is, adjustment holes are added to the lower parts of the left plate and the right plate, and the adjustment holes are waist-shaped holes or strip-shaped holes. The left and right ends of the first bottom plate are installed on the adjustment holes, that is, the installation position of the first bottom plate is lowered. When the water receiving pan is placed on the first bottom plate, the installation positions of the first bottom plate and the water receiving pan are lowered, so that the lower part of the evaporator does not abut against the upper part of the water receiving pan, thereby facilitating the smooth horizontal withdrawal of the water receiving pan.

[0040] In another embodiment of the present invention, the lower part of the evaporator can be raised to prevent the lower part of the evaporator from interfering with the extraction of the water receiving pan. The specific technical solution is as follows:

[0041] In one embodiment of the present invention, a middle partition 1 is arranged inside the air duct machine, and a notch 5 is preset at the lower part of the middle partition 1 for making way for the water receiving tray 2, that is, a notch 5 is preset between the lower part of the middle partition 1 and the upper part of the first bottom plate 10; wherein, there are multiple ways to install the middle partition 1, such as the left and right ends of the middle partition 1 are respectively and detachably installed on the left side plate 8 and the right side plate 9, at which time the lower part of the middle partition 1 is not in direct contact with the first bottom plate 10, that is, the interval between the lower part of the middle partition 1 and the first bottom plate 10 is the notch 5, and the water receiving tray 2 can move horizontally from the notch 5; for another example, legs are arranged at both the left and right ends of the lower part of the middle partition 1, that is, the middle partition 1 is installed on the first bottom plate 10 by two legs, and the notch 5 is between the two legs, and the water receiving tray 2 can move horizontally through between the two legs.

[0042] In one embodiment of the present invention, a support portion is provided on the upper portion of the water receiving tray 2, and a height b of the support portion is not lower than a height c of an edge of the water receiving tray 2. The support portion is used to lift up the lower portion of the evaporator 4, so that during the process of pulling out the water receiving tray 2, the lower portion of the evaporator 4 will not interfere with the upper portion of the water receiving tray 2.

[0043] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the support portion includes a sealing rib 3, which is arranged in the middle of the water receiving tray 2, and the upper portion of the sealing rib is in contact and sealed with the lower portion of the evaporator. The advantage of such an arrangement is that it can effectively prevent the airflow generated by the volute assembly from being blown out directly from the air outlet without passing through the evaporator.

[0044] It should be noted that the height b of the sealing rib is greater than or equal to the edge height c of the water receiving tray, and the width a of the notch 5 is greater than or equal to the height b of the sealing rib 3. The advantage of such a setting is that the evaporator 4 does not interfere with the horizontal extraction operation of the water receiving tray 2, that is, the water receiving tray can be extracted outward from the notch 5 of the middle partition; wherein, there are multiple ways to connect the sealing rib 3 to the water receiving tray 2, that is, the sealing rib 3 can be integrally arranged with the bottom of the water receiving tray 2, that is, when the water receiving tray 2 is manufactured, the sealing rib 3 is directly integrally arranged in the water receiving tray 2, and the sealing rib 3 The position corresponds to the lowermost position of the evaporator 4 for contact sealing, so as to ensure that the airflow generated by the volute assembly passes through the evaporator and is blown out from the air outlet; the sealing rib 3 and the water receiving tray 2 can also be separately arranged, that is, the sealing rib 3 is installed in the water receiving tray 2 by bolts, or by an adaptive connection method, that is, a boss is arranged in the water receiving tray 2, and a slot is arranged at the lower part of the sealing rib 3, and the boss is plugged into the slot, so that the sealing rib 3 of different heights can be flexibly replaced, so as to facilitate manual adjustment so that the lower part of the evaporator 4 is completely in contact and sealed with the lower part of the evaporator, so as to prevent the airflow from being discharged directly from the air outlet without passing through the evaporator; for example, other connection methods can also be used, such as a snap connection, that is, one end of the sealing rib 3 is hinged to the first mounting position of the water receiving tray 2, and the other end of the sealing rib 3 is snap-connected to the second mounting position of the water receiving tray 2. Again, no other detailed description is made, as long as the connection method that can realize the detachable connection between the sealing rib 3 and the water receiving tray 2 is applicable to the present technical solution.

[0045] Different from the above-mentioned embodiment, the supporting portion includes a supporting protrusion, which is arranged on the upper part of the water receiving tray and abuts against the lower part of the evaporator, that is, the supporting protrusion is used to support the lower part of the evaporator, the height of the supporting protrusion is greater than or equal to the edge height of the water receiving tray, and the width a of the notch 5 is greater than or equal to the height of the supporting protrusion.

[0046] It should be noted that, since the supporting protrusion supports the lower part of the evaporator 4, the lower part of the evaporator will not interfere with the horizontal movement of the water receiving tray, and thus the water receiving tray 2 can be horizontally pulled out through the notch 5 of the middle partition; in this embodiment, the supporting protrusion can be a point-shaped supporting protrusion, or it can be a supporting rib, that is, a strip-shaped supporting rib, so as to effectively support the lower part of the evaporator.

[0047] In one embodiment of the present invention, a pulling-up component 6 for raising the lower part of the evaporator 4 is provided in the heat exchange chamber, one end of the pulling-up component 6 is connected to the top plate 7 of the duct machine, the left side plate, the right side plate or the middle partition plate 1 of the duct machine, and the other end of the pulling-up component 6 is connected to the lower part of the evaporator 4, that is, the lower end of the evaporator 4 is pulled up by the pulling-up component 6, so that the lower part of the evaporator 4 does not abut against the water receiving tray 2, thereby preventing the evaporator 4 from interfering with the extraction operation of the water receiving tray 2.

[0048] In one embodiment of the present invention, Figure 5 As shown, the pulling assembly 6 includes a pull rod, that is, the upper end of the pull rod can be selectively installed on the upper part of one side of the middle partition 1 close to the heat exchange chamber, the lower part of the top plate 7, the upper part of the left plate 8 or the upper part of the right plate 9, and the lower end of the pull rod is connected to the lower part of the evaporator 4, so as to pull up the lower part of the evaporator 4 so that the evaporator 4 does not interfere with the water receiving tray 2; wherein, the pull rod can be a pull rod of fixed length or an adjustable rod of adjustable length; the adjusting rod includes at least two telescopic joints and positioning pins, and the two connected telescopic joints are connected by a socket connection. In order to facilitate manual adjustment of the length of the adjusting rod and control the height of the lower part of the evaporator 4, a plurality of adjustment holes are arranged on the upper part of each telescopic joint, and the positioning pin is inserted into the overlapping adjustment hole of the two telescopic joints on the adjusting rod, thereby realizing the fixing of the length of the adjusting rod.

[0049] In one embodiment of the present invention, different from the above embodiment, Figure 6 As shown, the pulling assembly 6 includes a driving part and a telescopic rod, the driving part is connected to one end of the telescopic rod, and the other end of the telescopic rod is connected to the lower part of the evaporator 4, and the driving part drives the telescopic rod to extend and retract to drive the lower part of the evaporator 4 to rise and fall.

[0050] It should be noted that the pull-up assembly 6 can be one group or multiple groups; when the pull-up assembly is one group, the upper end of the pull-up assembly 6 can be set on the middle partition, and can also be set on the lower part of the top plate of the duct machine, and the upper end position of the pull-up assembly 6 is higher than the lower part of the evaporator; when the pull-up assembly is multiple groups, the pull-up assembly 6 can be arranged at intervals, so that the lower part of the evaporator 4 can be smoothly raised or lowered; that is, the fixed part of the driving part is set on the middle partition 1 or the top plate, one end of the telescopic rod is set on the movable end of the driving part, and the other end of the telescopic rod is rotatably connected to the lower part of the evaporator 4; wherein the driving part can be an electric push rod or an electric cylinder, and the telescopic rod can be a connecting rod with a non-adjustable length, and can also be a movable end of the driving part Rod, one end of the telescopic rod away from the lower part of the evaporator 4 moves linearly with the active end of the electric push rod or the electric cylinder, that is, when the duct machine works normally, the driving unit drives the telescopic rod to extend, so that the lower part of the evaporator 4 contacts the upper part of the water receiving tray 2; when the water receiving tray 2 needs to be pulled out for cleaning, the driving unit drives the telescopic rod to contract, pulls the lower part of the evaporator 4 to a certain height, and avoids the lower part of the evaporator 4 from abutting against the upper part of the water receiving tray 2, so that the water receiving tray 2 moves horizontally relative to the evaporator 4, is pulled out from the notch 5 of the middle partition 1, and finally taken out from the return air port; because the electric push rod or the electric cylinder adopts the electric push rod or the electric cylinder that can realize linear motion in the prior art, it will not be described in detail here.

[0051] In an embodiment of the present invention, the duct air conditioner further comprises a return air outlet side plate, and an opening is formed on the return air outlet side plate for the water receiving tray 2 to be drawn out and avoided.

[0052] It should be noted that the opening can be the return air outlet of the duct air conditioner, or it can be an opening opened at the lower part of the return air outlet side panel, and the opening is below the return air outlet; the return air outlet side panel is a side panel arranged at the return air outlet, and the opening can be greater than or equal to the length dimension of the water receiving tray 2, so that the water receiving tray 2 can pass through the gap of the middle partition plate 1 when being pulled out, and be horizontally taken out from the opening of the return air outlet side panel; for example, the opening can be smaller than the length dimension of the water receiving tray 2, so that when the water receiving tray 2 is pulled out, after passing through the gap of the middle partition plate 1, the water receiving tray 2 can be rotated to be rotated and tilted and pulled out from the opening of the return air outlet side panel.

[0053] Although the present invention is disclosed as above, the present invention is not limited thereto.
