[0002] In the existing ducted air conditioner design, the structure of the same type of ducted air conditioner is relatively fixed, which limits the hoisting direction and position of the indoor unit, which may bring layout challenges. Due to these inherent limitations, the direction of the air duct during installation may become complicated or a more tortuous layout scheme may have to be adopted to accommodate the machine, thereby increasing the cost of the pipeline and the difficulty of installation.

[0003] On the other hand, ceiling-mounted air conditioner indoor units are divided into different specifications and models according to cooling / heating capacity. Each model has different overall machine sizes, resulting in different air outlet sizes. In order to match different building spaces and decoration requirements, each indoor unit often requires a customized mold to manufacture the matching air outlet components. This personalized production method significantly increases manufacturing costs.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0028] Combine the following Figure 1-Figure 6 The specific implementation mode of the hanging type air duct machine of the utility model is described.

[0029] like Figure 1As shown, the utility model provides a hanging type duct machine, including a casing and functional components arranged in the casing; the casing includes a first cover plate 111, a second cover plate 112 and at least two side plates 113, and the side plates 113 are respectively provided with hanging structures 120 at positions adjacent to the first cover plate 111 and the second cover plate 112; the casing is provided with an air outlet frame 130, and a wind shield plate 131 with adjustable length is provided in the air outlet frame 130, and the space between the wind shield plate 131 and the air outlet frame 130 forms an air outlet 132 for supplying air.

[0030] Specifically, the hoisting type duct machine mainly includes a casing and functional components arranged in the casing. The casing, as the basic supporting part of the entire device, mainly includes a first cover plate 111, a second cover plate 112 and at least two side plates 113. Among them, a hoisting structure 120 that can realize two-way hoisting is arranged at a position adjacent to the side plate 113 and the first cover plate 111 and the second cover plate 112. The two-way hoisting method breaks the limitations of the installation position of the traditional duct machine, so that the duct machine can not only be hoisted in the conventional direction, but also can be installed in the opposite direction according to the actual building structure or user needs, which greatly improves the adaptability and installation flexibility of the duct machine in various complex environments. At the air supply position, the casing is provided with an air outlet frame 130, and the air outlet frame 130 is embedded with an adjustable length windshield 131. By adjusting the position of the wind shield 131 in the air outlet frame 130, the gap area between the wind shield 131 and the air outlet frame 130 can be changed, thereby effectively adjusting the size of the air outlet 132 to meet different requirements for air conditioning airflow distribution in different scenarios.

[0031] In summary, the ceiling-mounted duct air conditioner of the utility model improves the practicality of the duct air conditioner in a variety of usage environments through the two-way ceiling-mounting function and the adjustable air outlet 132 design, and reduces the space limitations and layout difficulties that may be encountered during installation, providing users with a more efficient, convenient and flexible air-conditioning solution.

[0032] like Figure 4 As shown, according to a hanging type air duct machine provided by the utility model, the functional components include an evaporator 141, a first water receiving tray 142 and a second water receiving tray 143, the first water receiving tray 142 is arranged between the evaporator 141 and the first cover plate 111, and the second water receiving tray 143 is arranged between the evaporator 141 and the second cover plate 112. Specifically, the functional components are the key parts to realize the core functions of the air conditioning system, including but not limited to the evaporator 141 and the two water receiving trays located at different positions.

[0033] As an important component of the refrigeration cycle, the evaporator 141 has the main function of absorbing heat from the indoor air by evaporating the refrigerant internally during the operation of the air conditioner, thereby achieving the effect of cooling and dehumidifying. Due to the low temperature on the surface of the evaporator 141, the moisture in the indoor air will condense into liquid water droplets on its surface. In order to effectively handle the condensed water generated during operation, the hanging type duct air conditioner is provided with two water receiving pan structures. Among them, the first water receiving pan 142 is installed between the evaporator 141 and the first cover plate 111, and the second water receiving pan 143 is arranged between the evaporator 141 and the second cover plate 112, so as to ensure that no matter in which direction the duct air conditioner is hoisted (that is, no matter which side of the first cover plate 111 or the second cover plate 112 is facing downward), it can be ensured that at least one water receiving pan is located below the evaporator 141, thereby effectively capturing and collecting the condensed water dripping from the surface of the evaporator 141. The design of the double drain pan takes into account the drainage problems that may be encountered when the duct unit is hoisted in the forward and reverse directions. No matter how the duct unit is installed, it can ensure that condensed water will not leak into the ceiling or other unintended areas, but will be safely collected in the corresponding drain pan, thereby ensuring the safety of the duct unit's operation and the dryness of the operating environment.

[0034] Furthermore, according to a hanging type air duct machine provided by the utility model, the evaporator 141 is tilted between the first water receiving tray 142 and the second water receiving tray 143. The tilted evaporator 141 can optimize the natural flow path of the condensed water, which is conducive to the condensed water generated on the surface of the evaporator 141 to smoothly slide to the first water receiving tray 142 or the second water receiving tray 143 below. Specifically, during the operation of the air conditioner, after the moisture in the air is condensed due to the refrigeration effect of the evaporator 141, the formed condensed water droplets can flow smoothly into the first water receiving tray 142 or the second water receiving tray 143 located below along the inclined surface of the evaporator 141 with the help of gravity, preventing the condensed water from accumulating on the surface of the evaporator 141 and affecting its heat exchange efficiency, and also preventing the condensed water from leaking to an inappropriate position under the influence of the wind flow, causing damage to the equipment or a humid use environment.

[0035] like Figure 3 , Figure 5 and Figure 6 As shown, according to a hanging type air duct machine provided by the utility model, the hanging structure 120 includes a mounting portion 121 arranged on the side plate 113 and a hanging foot piece 122 detachably arranged on the mounting portion 121; wherein, the number of the mounting portions 121 close to the first cover plate 111 and the number of the mounting portions 121 close to the second cover plate 112 are the same and their positions correspond one to one. Specifically, on the two side plates 113 of the air duct machine, the positions close to the first cover plate 111 and the second cover plate 112 are respectively provided with the same number of mounting portions 121 in corresponding positions, so that no matter whether the air duct machine needs to be hung upward or downward, the corresponding fixing point can be found to install the hanging foot piece 122.

[0036] Furthermore, the same set of hanging feet 122 (for example, usually including four hanging feet 122 to provide sufficient support and balance) can be selectively installed on any set of mounting parts 121 close to the first cover plate 111 or close to the second cover plate 112 according to actual lifting requirements, instead of having to set the hanging feet 122 on both the upper and lower sides at the same time, which simplifies the installation process and reduces the cost of replacing or reconfiguring the lifting components due to changes in the layout of the duct machine.

[0037] Preferably, according to a hanging type air duct machine provided by the utility model, the hanging foot 122 includes a positioning plate 123 and a hanging plate 124, the positioning plate 123 is provided with a positioning structure matching the mounting portion 121, and the hanging plate 124 is provided with a hanging notch; the plate surface angle between the positioning plate 123 and the hanging plate 124 is 90 degrees. The positioning plate 123 is provided with a positioning structure matching the mounting portion 121 on the air duct machine side plate 113, such as a groove, a buckle or a threaded hole, etc., to ensure that the hanging foot 122 can be accurately and firmly installed in the specified position to prevent the equipment from loosening or shifting during use. The hanging plate 124 is provided with a hanging notch (such as a hook, a hanging ring or other forms of hanging interface) for connecting hanging bolts or a hanger system, etc., so as to safely and reliably hang the entire air duct machine on the ceiling or other supporting structure.

[0038] Among them, the angle between the positioning plate 123 and the hanging plate 124 is preferably 90 degrees, and the two together form a sheet metal structure similar to a right angle, which is not only conducive to providing vertical support, but also can ensure that the duct unit can maintain a horizontal and stable state when hanging in both positive and negative directions, thereby meeting the requirements for installation flexibility and stability of the duct unit under different spatial layouts and building structures. It can be understood that the structural directions of the mounting portion 121 close to the first cover plate 111 and the mounting portion 121 close to the second cover plate 112 are preferably set in opposite directions, so that when the hanging foot 122 is in the installed state, its hanging plate 124 is close to the first cover plate 111 or the second cover plate 112.

[0039] like Figure 6 As shown, according to a hanging type air duct machine provided by the utility model, a reinforcing rib 125 is provided between the positioning plate 123 and the hanging plate 124; the reinforcing rib 125, the positioning plate 123 and the hanging plate 124 form a triangular support structure. The reinforcing rib 125 can improve the structural strength between the positioning plate 123 and the hanging plate 124, and prevent the hanging foot 122 from deforming.

[0040] Specifically, the reinforcing rib 125, the positioning plate 123 and the hanging plate 124 form a triangular support structure, which has good stability and torsion resistance based on the geometric characteristics of the triangle. The reinforcing rib 125, as the hypotenuse of the triangle, together with the positioning plate 123 and the hanging plate 124, forms a stable triangular support shape, thereby improving the mechanical strength and durability of the hanging foot 122.

[0041] The reinforcing rib 125 can be made of metal material and firmly connected between the positioning plate 123 and the hanging plate 124 by welding or embedding. Alternatively, in a preferred case, the reinforcing rib 125 is realized by a stamping structure. Figure 6 As shown, the stamping structure forms a stamping groove on the wide-angle side of the hanging foot 122, thereby forming a stamping ridge on the right-angle inner side of the hanging foot 122, and the stamping ridge is perpendicular to the ridgeline between the positioning plate 123 and the hanging plate 124, thereby forming the above-mentioned reinforcing rib 125. The reinforcing rib 125 realized by the stamping structure does not require additional connecting components, reducing the material cost and the difficulty of manufacturing the hanging foot 122.

[0042] According to a hanging type air duct machine provided by the utility model, Figure 5 As shown, a hollow track 150 is provided between the mounting portion 121 close to the first cover plate 111 and the mounting portion 121 close to the second cover plate 112; Figure 6 As shown, the positioning plate 123 is provided with a limiter 126 that is slidably matched with the hollow track 150, and the limiter 126 has a limiter column with a diameter less than or equal to the width of the hollow track 150, and a limiter cap with a diameter greater than the width of the hollow track 150. The hollow track 150 plays a role in guiding and limiting the movement of the hanging foot member 122.

[0043] Among them, a limiting member 126 is provided on the positioning plate 123, which is slidably matched with the hollow track 150. The limiting member 126 mainly includes two parts: a limiting column with a diameter less than or equal to the width of the hollow track 150 and a limiting cap with a diameter greater than the width of the hollow track 150. The limiting column allows free sliding in the hollow track 150, so that the positioning plate 123 can be adjusted to a suitable position within the track range according to actual hoisting requirements; and the limiting cap plays a key role in preventing the positioning plate 123 from escaping from the track and ensuring its stable position. Through the above structure, the user can move the hanging foot member 122 through the hollow track 150 according to the specific requirements of the forward and reverse hoisting of the duct machine, so as to move the hanging foot member 122 to the mounting parts 121 at both ends of the hollow track 150.

[0044] Further, according to a hanging type air duct machine provided by the utility model, the hollow track 150 is in a broken line shape; Figure 5As shown, at the corner position of the hollow track 150, the hollow track 150 is provided with a loading and unloading hole 151, and the hole diameter of the loading and unloading hole 151 is greater than or equal to the diameter of the limiting cap.

[0045] The broken line hollow track 150 can be set to bypass or avoid important mechanical parts and electrical components inside the duct machine to avoid interference or damage to these key components when installing the foot member 122. On the other hand, the broken line hollow track 150 facilitates the staged positioning of the moving position of the foot member 122, which is convenient for users to install and remove the foot member 122 at different angles and positions.

[0046] In addition, a loading and unloading hole 151 is set at the corner position of the hollow track 150, and its hole diameter is at least greater than or equal to the diameter of the limit cap, so that when the hanging foot member 122 needs to be installed or removed, the limit cap can be removed from or inserted into the hollow track 150 through the loading and unloading hole 151.

[0047] like Figure 1 As shown, according to a hanging type air duct machine provided by the utility model, the air outlet frame 130 includes two short frames 133 parallel to the side plate 113, and two long frames 134 parallel to the first cover plate 111 and the second cover plate 112. The two short frames 133 and the two long frames 134 respectively constitute the four sides of the air outlet frame 130, wherein the two short frames 133 are arranged parallel to the side plate 113 to limit the height range of the air outlet; and the other two long frames 134 are arranged parallel to the first cover plate 111 and the second cover plate 112 to determine the maximum width of the air outlet.

[0048] The wind shield 131 may be a plurality of shields detachably mounted on the tuyere frame 130, or preferably Figure 2 As shown, the windshield 131 is a corrugated plate, and the windshield 131 has a fixed end connected to one of the short frames 133, and a movable end detachably mounted between the two long frames 134. The windshield 131 designed with a corrugated plate is stretchable, allowing the user to adjust its length according to actual needs, thereby changing the shielding range. The corrugated plate can maintain a certain rigidity to effectively guide the direction of the airflow, and can adapt to the requirements of air outlets 132 of different sizes by stretching, thereby improving the flexibility of the equipment.

[0049] In terms of specific installation methods, one end of the windshield 131 is preferably fixedly connected to one of the short frames 133 to form a fixed reference point, ensuring that the windshield 131 has a stable support base during the adjustment process. The other end of the windshield 131 is detachably installed between the two long frames 134, so that the windshield 131 can slide or be disassembled freely within a certain range, thereby conveniently adjusting the space between the windshield 131 and the air outlet frame 130, so as to achieve the purpose of accurately controlling the air volume of the air conditioner.

[0050] like Figure 1 and Figure 2 As shown, according to a hanging type air duct machine provided by the utility model, two long frames 134 are respectively provided with slide grooves, and at least a part of the wind shield 131 is slidably matched with the slide grooves; a plurality of positioning holes 135 corresponding to each other are respectively provided on the two long frames 134, and the movable ends are positioned and matched with the positioning holes 135. A part of the structure of the wind shield 131 is designed to cooperate with the slide groove, and can move smoothly along the slide groove, so that the user can adjust the position of the wind shield 131 in the air outlet frame 130.

[0051] In order to ensure that the windshield 131 can remain stable and will not slide randomly after being adjusted to any position, the two long frames 134 are preferably provided with a plurality of positioning holes 135 corresponding to the positions. The movable end of the windshield 131 has a structural design that matches these positioning holes 135, and the position of the windshield 131 can be fixed by inserting or screwing positioning members (such as screws or latches, etc.) into the positioning holes 135. In this way, in actual use, the user can slide the windshield 131 to an appropriate position according to specific needs, and lock the windshield 131 by cooperating with the positioning holes 135, which not only realizes the precise control of the air supply range of the air conditioner, but also ensures the safety and reliability of the equipment during operation.
