Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a duct air conditioner. Background Art

[0002] With the improvement of living quality, people's requirements for air conditioners are no longer satisfied with the heat exchange function. Duct air conditioners are a kind of concealed air conditioner installed in the ceiling, which can improve the aesthetics of interior decoration and are increasingly favored by consumers.

[0003] After long-term use, the ducted air conditioner needs to be cleaned and repaired. However, since the ducted air conditioner is installed in the ceiling, it is inconvenient to disassemble and assemble the whole machine. In addition, the operating space in the ceiling is very small, and there are many parts inside the ducted air conditioner, and the connection relationship is complicated. When disassembling and assembling, the various parts will interfere with each other, which is very inconvenient, seriously affecting the cleaning and maintenance efficiency. Users cannot complete the disassembly and cleaning operations by themselves. Summary of the invention

[0004] The problem solved by the invention is how to improve the convenience of disassembling and assembling the internal structure of the duct machine so as to facilitate the cleaning and maintenance of the duct machine.

[0005] To solve the above problems, the present invention provides a duct air conditioner, comprising a shell, a partition, a volute assembly and a heat exchange component, the shell is provided with a return air port and an air outlet, the return air port is arranged at the bottom of the shell, the partition divides the internal space of the shell into a fan chamber and a heat exchange chamber, the return air port is connected to the fan chamber, the air outlet is connected to the heat exchange chamber, the volute assembly is installed in the fan chamber, the heat exchange component is installed in the heat exchange chamber, and the volute assembly is detachably connected to the partition.

[0006] Compared with the prior art, the duct air conditioner of the present invention is provided with a partition in the middle of the shell, which divides the internal space of the shell into a fan chamber and a heat exchange chamber by the partition. The components in the fan chamber and the components in the heat exchange chamber will not interfere with each other when they move. The components in the fan chamber are all assembled together to form a volute assembly, and the volute assembly is detachably connected to the partition. When the duct air conditioner is inspected or cleaned, the connection between the volute assembly and the partition can be disassembled, and the volute assembly can be removed from the return air outlet of the shell as a whole without the need to disassemble the components separately, thereby greatly improving the convenience of disassembly and assembly of the components in the fan chamber.

[0007] Optionally, the volute assembly includes a mounting plate and at least one volute, the volute is connected to the mounting plate, a wind wheel is provided inside the volute, and the mounting plate is detachably connected to the partition.

[0008] The volute assembly is connected to the partition through the mounting plate. The connection between the two plate-like structures is reliable and the positioning is accurate. Both the mounting plate and the partition can play a supporting role to prevent the shell from deformation.

[0009] Optionally, the volute assembly further includes a motor bracket and a wind wheel motor, the motor bracket is connected to the mounting plate, and the wind wheel motor is mounted on the motor bracket.

[0010] The inside of the duct machine can be cleaned with a water gun, so the wind wheel motor needs to be removed first to prevent it from being damaged by water. The above technical solution installs the wind wheel motor and the motor bracket on the mounting plate as components of the volute assembly. When the volute assembly is disassembled, the wind wheel motor is removed together, and there is no need to disassemble the motor separately, which is easy to operate.

[0011] Optionally, the partition has at least one cleaning hole.

[0012] A cleaning hole is provided on the partition. When the volute assembly is removed, the tip of the water gun can be passed through the partition from the cleaning hole to clean the components in the heat exchange chamber.

[0013] Optionally, the mounting plate has an air outlet hole, and the air outlet hole is used for the volute to discharge air, and the projection of the cleaning hole on the mounting plate completely covers the air outlet hole.

[0014] Avoid the partition from interfering with the air outlet of the volute, and at the same time ensure that the size of the cleaning hole is large enough to facilitate the movement and rotation of the water gun, ensuring that the water gun can clean all positions in the heat exchange chamber.

[0015] Optionally, the shell includes a top plate, a side plate and a bottom plate, the heat exchange assembly includes an evaporator and a water receiving tray, the evaporator is connected to the top plate and / or the side plate, the water receiving tray is arranged on the bottom plate, and the evaporator is located above the water receiving tray.

[0016] The water collecting pan is arranged under the evaporator to collect the condensed water produced by the evaporator. When the heat exchange chamber is cleaned with a water gun, the sewage flowing down will also enter the water collecting pan to prevent water dripping from polluting the indoor environment. Dirt easily accumulates in the water collecting pan. The evaporator is connected to a gas-liquid pipeline, which is inconvenient to disassemble and assemble. In addition, there is heat exchange medium in the pipeline of the evaporator, and there is a certain safety risk in disassembling and assembling the evaporator. In the above technology, the evaporator is connected to the top plate and / or side plate of the shell, and has no connection or support relationship with the water collecting pan. Therefore, the water collecting pan can be removed for cleaning without dismantling the evaporator, which avoids the tedious operation of disassembling and assembling the evaporator and improves the convenience of disassembling and cleaning the duct machine.

[0017] Optionally, the water receiving tray includes a boss and surrounding edges arranged on all sides, the bottom of the evaporator contacts the boss, and the height of the boss is greater than or equal to the height of the surrounding edges.

[0018] The water receiving tray is provided with a boss which is larger than or equal to the surrounding edge, so as to limit the bottom position of the evaporator, avoid interference between the surrounding edge and the evaporator when the water receiving tray is moved, and facilitate the disassembly and assembly of the water receiving tray.

[0019] Optionally, the distance between the bottom of the partition and the bottom plate is greater than or equal to the height of the boss.

[0020] The distance between the bottom of the partition and the bottom plate is greater than or equal to the height of the boss, forming a give way structure. The water tray can be pulled out from under the partition without removing the partition and then the water tray, thereby improving the convenience of disassembly and assembly of the water tray. During the disassembly and cleaning or maintenance of the duct machine, the partition is not removed. The partition serves as the skeleton of the shell to support it and ensure the structural strength of the shell.

[0021] Optionally, the heat exchange assembly further includes a water pump, which is mounted on the partition.

[0022] The water pump is used to drain the accumulated water in the water receiving tray. In the above technical solution, the water pump is installed on the partition, which is convenient for disassembly and assembly of the water pump. There is no need to remove the partition before disassembling the water pump, thereby reducing the number of operation steps.

[0023] Optionally, a disassembly hole for disassembling and assembling the water pump is provided on the partition.

[0024] A disassembly hole is arranged on the partition, and the operator's hand or tool can pass through the disassembly hole to grab the water pump and move it, so as to facilitate the disassembly and assembly operation of the water pump. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In the description of the present invention, it should be noted that the terminology nouns in the various embodiments, such as "up", "down", "front", "back", "left", "right", etc., which indicate directions, are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the referred elements and devices must be operated according to the specific directions and defined operations and methods and structures in the specification. Such directional nouns do not constitute a limitation on the present invention.

[0040] A coordinate system XYZ is provided in the drawings of the embodiments of the present invention, wherein the positive direction of X represents the front, the reverse direction of X represents the back, the positive direction of the Y axis represents the top, the reverse direction of the Y axis represents the bottom, the positive direction of the Z axis represents the left, and the reverse direction of the Z axis represents the right.

[0041] The “inside” and “outside” mentioned in the embodiments of the present invention refer to a shell structure, where the side close to the center of the shell is the inside, and the side far from the center of the shell is the outside.

[0042] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] Combination Figures 1 to 12 As shown, this embodiment provides a duct air conditioner for regulating the indoor air environment. The duct air conditioner includes a housing 1, a return air port 15 is provided at the bottom (in the opposite direction of the Y axis) of the housing 1, an air outlet 16 is provided at the front (in the positive direction of the X axis), and a volute assembly 3 and a heat exchange component are provided in the housing 1. When the duct air conditioner is working, the gas in the environment enters the housing 1 from the return air port 15, and is blown out from the air outlet 16 after heat exchange. The return air port 15 is set at the bottom of the housing 1. When the duct air conditioner is disassembled and cleaned, the internal components of the housing 1 can be removed from the return air port 15, which has a larger operating space.

[0045] Combination Figure 1 As shown, the duct machine is installed in the indoor ceiling 7, and the bottom of the ceiling 7 has a hollow return air grille opening 71 at a position corresponding to the return air outlet 15, where the return air grille is installed, and the front side of the ceiling 7 has a hollow outlet air grille opening at a position corresponding to the outlet 16, where the outlet air grille is installed. When disassembling and cleaning the duct machine, the return air grille needs to be removed first, and the operator can enter the interior of the ceiling 7 from the return air grille opening 71 to perform the disassembly operation, and the removed parts can be taken out from the return air grille opening 71.

[0046] Combination Figure 2 and Figure 3 As shown, the housing 1 of the duct machine includes a top plate 11 arranged on the upper side (positive direction of the Y axis), a bottom plate 13 arranged on the lower side (negative direction of the Y axis), a back plate 14 arranged on the rear side (negative direction of the X axis), and two side plates 12 arranged on the left (positive direction of the Z axis) and right (negative direction of the Z axis), and a cavity for installing internal components is formed between the top plate 11, the bottom plate 13, the back plate 14 and the side plates 12. The housing 1 also includes a partition 2 arranged inside, which plays the role of skeleton support to ensure the structural strength of the housing 1. The partition 2 divides the internal space of the housing 1 into two parts, the internal space located on the front side of the partition 2 (positive direction of the X axis) is the heat exchange cavity 18, and the internal space located on the rear side of the partition 2 (negative direction of the X axis) is the fan cavity 17. The fan cavity 17 is connected to the return air port 15, the heat exchange cavity 18 is connected to the air outlet 16, the volute assembly 3 is installed in the fan cavity 17, and the heat exchange component is installed in the heat exchange cavity 18. When the duct air conditioner is working, ambient air is sucked in from the return air port 15, and the volute assembly 3 transports the gas in the fan chamber 17 to the heat exchange chamber 18, and the gas is blown out from the air outlet 16 after heat exchange by the heat exchange component, thereby achieving air conditioning.

[0047] The partition 2 separates the fan chamber 17 from the heat exchange chamber 18 to prevent the gas in the shell 1 from flowing freely between the fan chamber 17 and the heat exchange chamber 18, thereby ensuring the heat exchange efficiency. At the same time, the components in the fan chamber 17 and the components in the heat exchange chamber 18 are separated from each other and will not interfere with each other when moving, which is convenient for disassembly, cleaning or maintenance of the duct machine.

[0048] Combination Figures 1 to 7 As shown, in this embodiment, the volute assembly 3 installed in the fan chamber 17 integrates multiple parts such as the volute 33, the wind wheel 34, and the wind wheel motor 36 to form a component that can be moved as a whole, and the volute assembly 3 is detachably connected to the partition 2. When the duct air conditioner is inspected or cleaned, the volute assembly 3 can be separated from the partition 2, and the volute assembly 3 can be removed from the return air port 15 of the housing 1 as a whole, without the need to separately disassemble the volute 33, the wind wheel 34, the wind wheel motor 36 and other parts, which greatly improves the convenience of disassembly and assembly of the parts in the fan chamber 17 and improves the disassembly efficiency.

[0049] Specifically, the volute assembly 3 includes a mounting plate 31 and two volutes 33, and the volutes 33 are connected to the mounting plate 31. The mounting plate 31 has two air outlets 32 for the volutes 33 to discharge air, and the number and position of the air outlets 32 correspond to those of the volutes 33.

[0050] Each volute 33 is provided with a wind wheel 34, and the volute 33 can be opened up and down or left and right to take out the wind wheel 34 for maintenance or cleaning. In other embodiments, the number of volutes 33 can be 1-6, and the more the number of volutes 33, the greater the air supply of the air duct machine.

[0051] The volute assembly 3 also includes a motor bracket 35 and a wind wheel motor 36. The motor bracket 35 is connected to the mounting plate 31 and can be fixedly connected by a connection structure such as screws and / or buckles. The wind wheel motor 36 is installed on the motor bracket 35. The motor shaft of the wind wheel motor 36 is connected to the rotating shaft of the wind wheel 34 through a coupling. The wind wheel motor 36 is used to drive the wind wheel 34 to rotate. When the air duct machine is cleaned internally with a water gun, it is usually necessary to remove the wind wheel motor 36 first to prevent the wind wheel motor 36 from being damaged by water. In this embodiment, the wind wheel motor 36 and the motor bracket 35 are fixed on the mounting plate 31. When the volute assembly 3 is disassembled, the wind wheel motor 36 is removed together, and there is no need to disassemble the motor separately, which saves operating steps and improves the convenience of disassembly.

[0052] Preferably, the motor bracket 35 is disposed between the two volutes 33, which can reduce the length of the rotating shaft and reduce the burden. If the rotating shaft is too long, the wind wheel 34 may easily rotate eccentrically, causing noise and affecting the user experience.

[0053] Combination Figure 5 and Figure 6 As shown, the mounting plate 31 and the partition 2 are detachably connected by a connection structure such as a hook and / or a screw. Both the mounting plate 31 and the partition 2 are plate-shaped structures, and the positioning is accurate and the connection is reliable when the two are connected. Both the mounting plate 31 and the partition 2 can play a supporting role, and the double-layer support plate makes the housing 1 of the duct unit stronger and will not deform.

[0054] Combination Figure 6 As shown, there is a cleaning hole 21 in the middle of the partition 2. When the volute assembly 3 is installed, the mounting plate 31 covers the cleaning hole 21 to prevent air leakage between the fan chamber 17 and the heat exchange chamber 18. When the volute assembly 3 is removed, the partition 2 and the cleaning hole 21 are exposed. A water gun can enter the fan chamber 17 from the return air port 15, and then the gun head can pass through the partition 2 from the cleaning hole 21 into the heat exchange chamber 18 to clean the components in the heat exchange chamber 18.

[0055] Preferably, when the volute assembly 3 is installed, the projection of the cleaning hole 21 on the mounting plate 31 completely covers the air outlet 32 ​​of the mounting plate 31, so as to prevent the partition 2 from interfering with the air outlet of the volute 33. At the same time, the cleaning hole 21 is large in size, which is convenient for the water gun to move and rotate, so that the water gun can clean all positions in the heat exchange chamber 18, ensuring the cleaning effect.

[0056] In other embodiments, the number of the cleaning holes 21 may be multiple, and the projection of the cleaning holes 21 on the mounting plate 31 may cover the air outlet holes 32 .

[0057] Combination Figure 2 and Figure 8 As shown, a heat exchange component is installed in the heat exchange chamber 18, and the heat exchange component includes an evaporator 4, a water receiving tray 5 and a water pump 6. A heat exchange medium is introduced into the evaporator 4, and the temperature of the gas flowing through the evaporator 4 will change, thereby completing the heat exchange. The water receiving tray 5 is arranged below the evaporator 4, and is used to receive the condensed water generated by the evaporator 4 to prevent the condensed water from dripping onto the ceiling 7 or indoors and polluting the environment. The water pump 6 is used to discharge the condensed water collected in the water receiving tray to avoid liquid accumulation. In other embodiments, the water pump 6 may not be provided, and a drain nozzle may be directly provided on the water receiving tray 5 to discharge the accumulated water.

[0058] After the duct air conditioner has been used for a long time, the water receiving pan 5 is prone to accumulate dirt, and the water receiving pan 5 needs to be cleaned to avoid affecting the drainage effect and the air quality of the duct air conditioner. In the prior art, the water receiving pan 5 is arranged below the evaporator 4 and supports the evaporator 4. In addition, the bottom of the evaporator 4 contacts the middle low point of the water receiving pan 5, and the bottom position of the evaporator 4 is lower than the highest position of the edges around the water receiving pan 5, so that the water receiving pan 5 cannot move freely without removing the evaporator 4. When removing the water receiving pan 5 for cleaning, the evaporator 4 needs to be removed first, but the evaporator 4 itself needs to be connected to the gas-liquid pipeline for conveying the heat exchange medium. To remove the evaporator 4, the gas-liquid pipeline needs to be disconnected first, which is inconvenient to disassemble and assemble, and the pipeline of the evaporator 4 will have residual heat exchange medium. There are certain safety risks in disassembling and assembling the evaporator 4.

[0059] This embodiment improves the installation structure and matching relationship of each component of the heat exchange assembly, the water receiving pan 5 is arranged on the bottom plate 13, and the evaporator 4 is connected to the top plate 11 and the side plate 12 of the housing 1. The weight of the evaporator 4 is borne by the top plate 11 and the side plate 12, and the water receiving pan 5 will not be subjected to the pressure of the evaporator 4 and will not play a supporting role. There is no connection relationship between the water receiving pan 5 and the evaporator 4, so the water receiving pan 5 can be removed separately, avoiding the cumbersome operation of disassembling and assembling the evaporator 4.

[0060] In other embodiments, the evaporator 4 can be connected to the top plate 11 or the side plate 12 separately. The evaporator 4 can be cleaned directly by a water gun in the installed state, and the sewage flowing down also enters the water receiving tray 5, and then the water receiving tray 5 is removed and cleaned separately.

[0061] Combination Figure 2 As shown, the water receiving pan 5 is provided with a surrounding edge 52 around it, so that the water receiving pan 5 has a certain water storage space to prevent water from flowing out from around the water receiving pan 5. The middle part of the water receiving pan 5 is provided with an upwardly protruding boss 51, and the bottom of the evaporator 4 contacts the boss 51 to form a sealing structure to prevent the air in the heat exchange chamber 18 from leaking from the gap between the evaporator 4 and the water receiving pan 5 without passing through the evaporator 4 for heat exchange, thereby ensuring the heat exchange efficiency.

[0062] In addition, the boss 51 serves to limit the bottom height of the evaporator 4 to prevent the water tray 5 from interfering with the evaporator 4 when it is moved. The height of the boss 51 is greater than or equal to the height of the edge 52, so that the water tray 5 can be moved horizontally backward from the installation position when it is removed, and the edge 52 will not interfere with the evaporator 4. After the water tray 5 is moved to the fan chamber 17, it can be moved downward and taken out from the return air port 15.

[0063] Preferably, in order to facilitate the removal of the water tray 5, the partition 2 has a clearance structure, and there is a gap between the partition 2 and the bottom plate 13 for the water tray 5 to pass through. When the water tray 5 is removed, it can be directly pulled out from under the partition 2 without removing the partition 2 first, saving work. At the same time, the partition 2 does not need to be removed during the disassembly and cleaning or maintenance of the duct machine. The partition 2 can serve as a support for the skeleton of the shell 1 to ensure the structural strength of the shell 1 and prevent the shell 1 from being deformed due to the weight of the evaporator 4.

[0064] In order to prevent the partition 2 from interfering with the movement of the water receiving tray 5, the distance between the bottom of the partition 2 and the bottom plate 13 is greater than or equal to the height of the boss 51, that is, the height of the gap between the partition 2 and the bottom plate 13 is greater than or equal to the thickness of the thickest part of the water receiving tray 5, so that the water receiving tray 5 can move horizontally and be pulled out from under the partition 2.

[0065] The water pump 6 is relatively large and will interfere with the movement of the water tray 5. Therefore, the water pump 6 needs to be removed before removing the water tray 5. In the prior art, the water pump 6 is installed on the water tray 5. If the water pump 6 is directly removed without removing the partition 2, the operating space is limited and the disassembly and assembly operation is very inconvenient.

[0066] Combination Figure 8 and Fig. 9 As shown, in this embodiment, the water pump 6 is mounted on the partition 2 and connected by a connection structure such as a buckle and / or a screw. The operator's hand or tool can enter the heat exchange cavity 18 through the cleaning hole 21 to disassemble the water pump 6, which has a larger operating space and can directly disassemble the water pump 6 without removing the partition 2, which is convenient to operate.

[0067] Preferably, a disassembly hole 22 is provided on the partition plate 2, and the position of the disassembly hole 22 corresponds to the water pump 6. The operator's hand or tool can pass through the disassembly hole 22 to grab the water pump 6 for movement, making it more convenient to disassemble and assemble the water pump 6.

[0068] Combination Figures 9 to 12 As shown, the steps for disassembling and cleaning the duct machine of this embodiment are described below:

[0069] S1. Combination Fig. 9 As shown, when the duct unit is disassembled for cleaning, the return air grille installed on the ceiling 7 is first removed to expose the return air grille opening 71 and the return air inlet 15 of the duct unit, and the internal components of the duct unit can be removed from the return air inlet 15.

[0070] S2, directly disconnect the connection between the mounting plate 31 and the partition plate 2, and remove the volute assembly 3 as a whole from the return air port 15. Fig.10 As shown, after the volute assembly 3 is removed, the partition 2 and the cleaning hole 21 are exposed. The removed volute assembly 3 can be disassembled to clean the volute 33, the wind wheel 34 and other components on the ground or a tabletop with a large operating space, and then the components are assembled together to form the volute assembly 3 after cleaning, which is convenient for subsequent installation.

[0071] S3, a water gun enters the interior of the air duct housing 1 from the return air port 15, passes the gun head through the cleaning hole 21 of the partition 2, and sprays water to clean the evaporator 4. The gun head can be moved and rotated during cleaning to ensure that all parts of the evaporator 4 are cleaned. The cleaning water flows into the water receiving tray 5 and is discharged through the water pump 6 or discharged from the drainage nozzle of the water receiving tray 5.

[0072] S4. The operator passes a tool or hand through the disassembly hole 22 to grab the water pump 6, disconnects the water pump 6 from the partition 2, rotates the water pump 6 from the disassembly hole 22 to the fan cavity 17, or moves the water pump 6 from the cleaning hole 21 to the fan cavity 17, and then takes the water pump 6 out of the return air port 15. After the water pump 6 is removed, the internal structure of the duct fan is as follows: Fig.11 shown.

[0073] S5, drag the water tray 5 horizontally backward and pull it out from the gap between the partition 2 and the bottom plate 13, move the water tray 5 to the fan chamber 17, and then move the water tray 5 downward and take it out from the return air port 15. After the water tray 5 is removed, the internal structure of the duct fan is as follows Fig.12 The removed water receiving tray 5 can be cleaned separately.

[0074] The above steps complete the disassembly and cleaning of the duct air conditioner. The installation steps are opposite to the disassembly steps. The water tray 5, water pump 6, volute assembly 3 and return air grille need to be installed in sequence.

[0075] The duct machine provided in the above embodiment has the advantages of convenient disassembly and assembly of the internal structure, and is convenient for maintenance and cleaning. Users can complete the disassembly and cleaning operations by themselves without hiring special maintenance personnel, which saves the use cost. Therefore, it has high practical value and market promotion prospects.

[0076] 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.
