[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0042] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0043] Please refer to the following Figure 1-Figure 10 The duct machine 100 according to the embodiment of the present invention is described. The duct machine 100 according to the embodiment of the present invention is, for example, a vertical duct machine 100 .

[0044] like Figure 1 As shown, the air duct machine 100 according to the embodiment of the utility model includes a casing 1, a heat exchanger 2, a fan assembly 4 and a water receiving tray assembly 3.

[0045] The casing 1 is used to be placed vertically on the ground, and the casing 1 is provided with an air inlet and an air outlet, the heat exchanger 2 is arranged in the casing 1, the fan assembly 4 is arranged in the casing 1 and is located on one side of the heat exchanger 2, the fan assembly 4 drives the air to enter the casing 1 from the air inlet, and the air exchanges heat with the heat exchanger 2 to form a heat exchange airflow, and then is driven by the fan assembly 4 to enter the room from the air outlet.

[0046] The casing 1 may have multiple air inlets, for example, one air inlet may be an air inlet for outdoor fresh air, and another air inlet may be an air inlet for indoor air. In addition, the fan assembly 4 may be located on one side of the heat exchanger 2 adjacent to the air outlet.

[0047] In this way, the duct machine 100 can selectively control outdoor fresh air and indoor air to enter the casing 1 through the air inlets through multiple air inlets, and the outdoor fresh air or indoor air can form a heat exchange airflow after heat exchange with the heat exchanger 2, and then be driven by the fan assembly 4 to be introduced into the room from the air outlet, thereby realizing indoor cooling or heating.

[0048] The water tray assembly 3 is arranged on the side of the heat exchanger 2 facing the air inlet and avoiding the air inlet. This not only improves the integration of the internal structure of the air duct machine 100, which is conducive to reducing the size of the air duct machine 100, but also ensures that air enters the casing 1 from the air inlet normally to ensure the formation of heat exchange airflow in the air duct machine 100.

[0049] It can be understood that the water tray assembly 3 is used to receive the condensed water falling from the surface of the heat exchanger 2. Such a configuration can, on the one hand, prevent the condensed water from flowing out of the duct machine 100 and affecting the environment, and on the other hand, collect the condensed water so that it can be reused.

[0050] Combination Figure 2 As shown, the water receiving tray assembly 3 includes a water receiving tray component 301 and a heat-insulating component 302. The heat-insulating component 302 is arranged in the water receiving tray component 301, and the water receiving tray component 301 can be insulated during the operation of the air duct machine 100. This can reduce the condensed water in the water receiving tray from absorbing the heat of the surrounding air, avoid condensation caused by the cold air outside the water receiving tray, and prevent the condensed water from falling from the water receiving tray, thereby improving the safety of the air duct machine 100.

[0051] Furthermore, the water receiving tray 301 includes a water receiving tray body 3011 and a cover plate 3012 , wherein a side of the water receiving tray body 3011 away from the heat exchanger 2 in the first direction is open.

[0052] In an embodiment of the utility model, the water receiving pan body 3011 can not only be used to receive the condensed water falling from the heat exchanger 2, but also provide a setting space for the thermal insulation component 302. By opening the side of the water receiving pan body 3011 away from the heat exchanger 2, it is convenient to install the thermal insulation component 302 in the water receiving pan assembly 3.

[0053] It should be noted that, in the embodiment of the present utility model, the condensed water on the heat exchanger 2 falls into the water receiving tray assembly 3 along the first direction under the action of gravity.

[0054] Furthermore, combined with Figure 1-Figure 3 As shown, the cover plate 3012 is arranged on a side of the water receiving pan body 3011 away from the heat exchanger 2 in the first direction, so that the cover plate 3012 and the water receiving pan body 3011 can jointly define a receiving groove 3013, and the heat preservation member 302 can be arranged in the receiving groove 3013.

[0055] It can be understood that the insulation component 302 is arranged between the water receiving tray body 3011 and the cover plate 3012, so that the water receiving tray body 3011 and the cover plate 3012 can protect the insulation component 302, and prevent the water receiving tray assembly 3 from causing loss of the insulation component 302 during assembly and transportation, thereby ensuring the insulation reliability of the insulation component 302 when the duct machine 100 is working.

[0056] In this arrangement, the cover plate 3012 is covered on the water receiving tray body 3011, and the thermal insulation component 302 can be fixed in the water receiving tray assembly 3. In this way, during the production process of the duct machine 100, the fixing operation of the thermal insulation component 302 can be reduced, which is conducive to simplifying the production of the duct machine 100.

[0057] Furthermore, the heat-insulating component 302 is disposed between the water receiving tray body 3011 and the cover plate 3012 , so that the heat-insulating component 302 can insulate the condensed water received in the water receiving tray body 3011 .

[0058] Combination Figure 1 and Figure 2 As shown, one side of the water receiving pan body 3011 in the first direction is the heat exchanger 2, and the other side of the water receiving pan body 3011 in the first direction is the insulation component 302. This can prevent the condensed water in the water receiving pan body 3011 from absorbing the heat of the surrounding air, and can effectively reduce the condensation generated on the outside of the water receiving pan assembly 3, thereby effectively improving the safety of the duct machine 100.

[0059] In some embodiments of the present invention, a first perforation is provided on the water tray body 3011, and a second perforation is provided on the cover plate 3012. The first perforation corresponds to the second perforation and is connected and fixed by a fastener.

[0060] Specifically, the first perforation and the second perforation have simple structures and can be easily opened on the water receiving tray body 3011 and the cover plate 3012 , which is conducive to reducing the processing difficulty of the water receiving tray assembly 3 and improving the production efficiency of the water receiving tray assembly 3 .

[0061] Furthermore, the first fastener corresponds to the second fastener, which can facilitate the fastener to pass through the first perforation and the second perforation, so that the water receiving tray body 3011 and the cover plate 3012 can be easily fixed, which can simplify the assembly of the water receiving tray body 3011 and the cover plate 3012, which is beneficial to improving the assembly convenience of the air duct machine 100.

[0062] Furthermore, the water receiving tray body 3011 and the cover plate 3012 are connected by fasteners, and the connection is reliable, which can ensure the connection reliability of the water receiving tray body 3011 and the cover plate 3012, and further ensure the structural reliability of the water receiving tray member 301.

[0063] It should be noted that the number of the first perforation and the second perforation can be one, or can be at least two, and what needs to be ensured is that the number of the first perforation and the second perforation corresponds to each other, and the number of the fasteners and the first perforations and the second perforations all correspond to each other.

[0064] In other embodiments of the present invention, Fig.10 , Fig.11 and Fig.13 As shown, a first clamping portion 30111 is provided on the water receiving tray body 3011, and a second clamping portion 30121 is provided on the cover plate 3012. One of the first clamping portion 30111 and the second clamping portion 30121 is a buckle, and the other is a slot, and the buckle and the slot are snap-fitted.

[0065] Specifically, the first clamping portion 30111 and the second clamping portion 30121 have a simple structure and can be easily opened on the water receiving tray body 3011 and the cover plate 3012, which helps to reduce the processing difficulty of the water receiving tray assembly 3 and improve the production efficiency of the water receiving tray assembly 3.

[0066] Furthermore, the water receiving tray body 3011 and the cover plate 3012 are connected and fixed to each other by the snap-fitting cooperation of the first snap-fitting portion 30111 and the second snap-fitting portion 30121, which can not only reduce the difficulty of installing the water receiving tray body 3011 and the cover plate 3012, but also ensure the connection reliability of the water receiving tray body 3011 and the cover plate 3012, thereby not only improving the assembly convenience of the water receiving tray component 301, but also ensuring the structural reliability of the water receiving tray component 301.

[0067] Furthermore, the snap-fitting of the first snap-fitting portion 30111 and the second snap-fitting portion 30121 includes but is not limited to the snap-fitting of the snap buckle and the snap slot. The snap buckle and the snap slot have a simple structure, are easy to install, and have reliable snap-fitting. This can not only effectively improve the installation efficiency of the water receiving tray body 3011 and the cover plate 3012, but also ensure the structural reliability of the water receiving tray body 3011 and the cover plate 3012.

[0068] In some further embodiments of the present invention, Fig.10 , Fig.11 and Fig.13 As shown, a first perforation is provided on the water receiving tray body 3011, and a second perforation is provided on the cover plate 3012. The first perforation corresponds to the second perforation and is connected and fixed by a fastener. A first clamping portion 30111 is provided on the water receiving tray body 3011, and a second clamping portion 30121 is provided on the cover plate 3012. One of the first clamping portion 30111 and the second clamping portion 30121 is a buckle, and the other is a slot, and the buckle and the slot are engaged with each other.

[0069] Specifically, the first perforation and the second perforation can be partially provided at the connection position between the water receiving tray body 3011 and the cover plate 3012, and similarly, the buckle and the slot can be partially provided. Both connection structures can ensure the connection reliability between the water receiving tray body 3011 and the cover plate 3012.

[0070] It can be understood that compared with the connection method in which the fastener passes through the first perforation and the second perforation, the connection of the buckle and the slot is more convenient and quicker. Therefore, after setting the structure of the buckle and the slot, the setting of the first perforation and the second perforation can be reduced accordingly. This not only ensures the connection reliability between the water receiving tray body 3011 and the cover plate 3012, but also reduces the use of fasteners, thereby further simplifying the assembly operation of the water receiving tray member 301 to improve the assembly convenience of the water receiving tray assembly 3.

[0071] In some specific embodiments of the present invention, at least one of the cover plate 3012 and the water receiving tray body 3011 is made of a flame retardant plastic material. Specifically, the flame retardant plastic material not only has flame retardancy, but also has a relatively light weight.

[0072] Such a configuration can improve the safety of the water receiving tray 301, meet the safety standards of product design, and also help to reduce the weight of the water receiving tray 301, making the assembly and transportation process of the air duct machine 100 easier.

[0073] In some other specific embodiments of the present invention, the portion of the water receiving tray 301 away from the heat exchanger 2 may be made of sheet metal material.

[0074] In some specific embodiments of the present invention, the heat-insulating member 302 is a heat-insulating foam. The heat-insulating foam has a small mass and a good heat-insulating effect, and can ensure the heat-insulating effect of the water tray assembly 3.

[0075] The materials used for the insulation foam include but are not limited to polystyrene foam and polypropylene foam.

[0076] In some embodiments of the present application, Figure 2 As shown, the dimension of the heat-insulating component 302 in the first direction is h, and h≤15 mm.

[0077] The size of the heat preservation member 302 in the first direction cannot be too large, otherwise the size of the water receiving tray assembly 3 will be increased, thereby increasing the structural size of the duct unit 100. In order to meet the structural design of the duct unit 100, the size of the heat preservation member 302 in the first direction is set not to exceed the first parameter value. For example, the first parameter value can be 15 mm, 14 mm, or 13 mm. Consider selecting a suitable specific parameter in the specific design.

[0078] In some embodiments of the present application, Figure 2 As shown, the dimension of the heat-insulating member 302 in the first direction is h, which is ≥ 10 mm.

[0079] The size of the heat preservation member 302 in the first direction cannot be too small, otherwise it will affect the heat preservation effect of the heat preservation member 302 on the condensed water on the water tray body 3011. To ensure the heat preservation effect of the heat preservation member 302, the size of the heat preservation member 302 in the first direction is set to be not less than the second parameter value. For example, the second parameter value can be 10mm, 11mm, or 12mm. Consider selecting a suitable specific parameter in the specific design.

[0080] In some specific embodiments of the present invention, Figure 2 and Fig.13 As shown, the cover plate 3012 includes a main body portion 30122 and a flange portion 30123. The main body portion 30122 is located on a side of the water receiving tray body 3011 in the first direction away from the heat exchanger 2. The main body portion is mainly used to receive the condensed water falling from the heat exchanger 2 to collect the condensed water.

[0081] The flange portion 30123 is arranged on at least a portion of the circumferential edge of the main body portion 30122, and is bent and extended relative to the main body portion 30122 toward the first direction on one side close to the heat exchanger 2. The flange portion 30123 stops at the outer side of the edge of the water receiving pan body 3011. Such an arrangement can prevent water droplets from falling on the outside of the water receiving pan member 301 after condensation is generated on the surface of the water receiving pan member 301. In this way, condensed water generated on the edge and surface of the water receiving pan member 301 can enter the water receiving pan body 3011 along the flange, which is beneficial to improving the safety of the air duct machine 100.

[0082] In some specific embodiments of the present invention, Figure 1 , Figure 6 and Figure 8 As shown, the heat exchanger 2 includes two straight heat exchangers 201 arranged back to back and tilted in the second direction, one end of the two straight heat exchangers 201 are connected to each other to form a connecting end 2011, and the other end of the two straight heat exchangers 201 is a free end 2012.

[0083] Specifically, in order to improve the heat exchange efficiency of the heat exchanger 2 and enhance the structural compactness of the product in the vertical duct unit 100, one end of the two straight-section heat exchangers 201 are connected to each other and the other ends are separated from each other. The heat exchange airflow enters between the two straight-section heat exchangers 201. Such an arrangement can improve the heat exchange efficiency between the heat exchange airflow and the heat exchanger 2.

[0084] Two sealing plates 202 are arranged between the two straight heat exchangers 201, and the two sealing plates 202 respectively seal the two sides of the third direction of the two straight heat exchangers 201. The sealing plates 202 can prevent the heat exchange airflow from flowing out from the two sides of the third direction of the two straight heat exchangers 201, and can ensure the flow of the heat exchange airflow.

[0085] In addition, the two sealing plates 202 cover both sides of the two straight-section heat exchangers 201 in the third direction, which can ensure that the condensed water on the heat exchanger 2 accurately falls onto the water receiving tray body 3011 on one side of the heat exchanger 2 in the first direction. Such an arrangement can ensure the reliability of the condensed water entering the water receiving tray assembly 3.

[0086] In some specific embodiments of the present invention, Figure 4 , Figure 6 , Figure 7 and Fig.11 As shown, the water receiving tray 301 is provided with a matching plate 3014 extending in a first direction toward the heat exchanger 2, which can improve the air tightness between the water receiving tray 301 and the sealing plate 202, reduce the leakage of the heat exchange airflow, and thus help to ensure the air supply volume of the air duct machine 100.

[0087] Furthermore, the matching plate 3014 is located between the two sealing plates 202 , and at least a portion of the end of the matching plate 3014 is bent in a third direction toward a side away from the corresponding sealing plate 202 , which facilitates condensed water on the sealing plate 202 to enter the water receiving tray 301 .

[0088] In addition, the matching plate 3014 is disposed adjacent to the sealing plate 202 , which can reduce the influence of the matching plate 3014 on the heat exchange airflow, and further reduce the influence of the structure on the water receiving tray 301 on the air volume of the air duct unit 100 .

[0089] Furthermore, there are two matching plates 3014, and they correspond one-to-one to the two sealing plates 202, so that the two matching plates 3014 can be matched with the two sealing plates 202 respectively, which can not only improve the airtightness between the two sealing plates 202 and the water receiving tray 301 at the same time, but also allow the condensed water on the two sealing plates 202 to enter the water receiving tray 301.

[0090] A water guiding slope 30141 is formed on the matching plate 3014. With such a configuration, the gap between the matching plate 3014 and the sealing plate 202 can be enlarged, and the efficiency of water passing between the matching plate 3014 and the sealing plate 202 can be increased, so that the condensed water on the sealing plate 202 can quickly enter the water receiving pan body 3011 and be drained in time, which can prevent the condensed water from accumulating between the two sealing plates 202 and affecting the heat exchange efficiency of the heat exchanger 2.

[0091] The first direction, the second direction and the third direction are perpendicular to each other.

[0092] In some embodiments of the present invention, Figure 2 , Figure 7 and Figure 8 As shown, a plane parallel to the first direction and perpendicular to the second direction is set as a reference plane, and the inclination angle of the water guide slope 30141 relative to the reference plane is α, and α satisfies the relationship: 1°≤α≤3°.

[0093] In some embodiments of the present application, the inclination angle of the water guiding slope 30141 relative to the reference plane is α, and α≤3°.

[0094] The inclination angle of the water guide slope 30141 relative to the reference plane cannot be too large. If it is too large, the gap distance between the matching plate 3014 and the sealing plate 202 will be too large, which will reduce the air tightness between the sealing plate 202 and the water receiving tray 301, and easily cause leakage of the heat exchange air flow, thereby affecting the air supply volume of the air duct unit 100. In order to ensure the air tightness between the sealing plate 202 and the water receiving tray 301, the inclination angle of the water guide slope 30141 relative to the reference plane is set not to exceed the third parameter value. For example, the third parameter value can be 3.0°, 2.9°, or 2.8°. Consider selecting a suitable and specific parameter in the specific design.

[0095] In some embodiments of the present application, the inclination angle of the water guiding slope 30141 relative to the reference plane is α, and α≥1°.

[0096] The inclination angle of the water guide slope 30141 relative to the reference plane cannot be too small. If it is too small, the gap between the matching plate 3014 and the sealing plate 202 will be too small, which will make it difficult for the water on the sealing plate 202 to enter the water receiving pan body 3011, and it is easy to cause too much water to accumulate between the two sealing plates 202. Excessive water accumulation will affect the safety of the heat exchanger 2. In order to ensure that the condensed water on the sealing plate 202 quickly enters the water receiving pan body 3011, the inclination angle of the water guide slope 30141 relative to the reference plane is set to be not less than the fourth parameter value. For example, the fourth parameter value can be 1.0°, 1.1°, or 1.2°. Consider selecting a suitable and specific parameter in the specific design.

[0097] In some embodiments of the present application, the inclination angle of the water guiding slope 30141 relative to the reference plane is α, 1°≤α≤3°.

[0098] By setting the inclination angle of the water guiding slope 30141 relative to the reference plane between 1° and 3°, not only the air tightness between the sealing plate 202 and the water receiving tray 301 can be ensured, but also the condensed water on the sealing plate 202 can quickly enter the water receiving tray body 3011 to ensure the safety of the heat exchanger 2.

[0099] In some specific embodiments of the present invention, Figure 7 As shown, the length of the matching plate 3014 is L1, the dimension of the water guiding slope 30141 in the first direction is L2, and 0.3L1≤L2≤0.7L1.

[0100] In some embodiments of the present application, the length of the matching plate 3014 is L1, the dimension of the water guiding slope 30141 in the first direction is L2, and L2≤0.7L1.

[0101] The size of the water guide slope 30141 in the first direction cannot be too large. If it is too large, the gap between the matching plate 3014 and the sealing plate 202 will be too large, which will reduce the air tightness between the sealing plate 202 and the water receiving tray 301, easily causing leakage of the heat exchange air flow and thus affecting the air supply volume of the air duct unit 100. In order to ensure the air tightness between the sealing plate 202 and the water receiving tray 301, the ratio of the size of the water guide slope 30141 in the first direction to the length of the matching plate 3014 is set to not exceed the fifth parameter value. For example, the fifth parameter value can be 0.7, 0.6, or 0.5. Consider selecting a suitable and specific parameter in the specific design.

[0102] In some embodiments of the present application, the length of the matching plate 3014 is L1, the dimension of the water guiding slope 30141 in the first direction is L2, and L2 ≥ 0.3L1.

[0103] The size of the water guide slope 30141 in the first direction cannot be too small. If it is too small, the gap between the matching plate 3014 and the sealing plate 202 will be too small, which will make it difficult for the water on the sealing plate 202 to enter the water receiving pan body 3011, and it is easy to cause too much water to accumulate between the two sealing plates 202. Excessive water accumulation will affect the safety of the heat exchanger 2. In order to ensure that the condensed water on the sealing plate 202 quickly enters the water receiving pan body 3011, the ratio of the size of the water guide slope 30141 in the first direction to the length of the matching plate 3014 is set to be not less than the sixth parameter value. For example, the sixth parameter value can be 0.3, 0.4, or 0.5. Consider selecting a suitable and specific parameter in the specific design.

[0104] In some embodiments of the present application, the length of the matching plate 3014 is L1, the size of the water-guiding slope 30141 in the first direction is L2, 0.3L1≤L2≤0.7L1, which can not only ensure the airtightness between the sealing plate 202 and the water receiving tray 301, but also enable the condensed water on the sealing plate 202 to quickly enter the water receiving tray body 3011, so as to ensure the safety of the heat exchanger 2.

[0105] In some specific embodiments of the present invention, Figure 8 , Fig. 9 , Fig.11 and Fig.12 As shown, a limiting portion 3015 is provided on the water receiving tray body 3011, and the limiting portion 3015 extends along the third direction on both sides of the second direction of the water receiving tray body 3011. The free end 2012 of the heat exchanger 2 contacts the limiting portion 3015, which can provide support for the heat exchanger 2.

[0106] Furthermore, the first direction of the limiting portion 3015 is inclined toward one end of the heat exchanger 2, which can ensure the tightness of the fitting between the limiting portion 3015 and the heat exchanger 2, prevent condensed water from flowing out through the contact end of the heat exchanger 2 and the limiting portion 3015, and ensure the reliability of the condensed water falling on the water receiving tray body 3011.

[0107] Furthermore, a plurality of drain ports 3016 are provided on the limiting portion 3015 and are spaced apart along a third direction on the limiting portion 3015 , so that condensed water between the two straight-section heat exchangers 201 can flow to the water receiving pan body 3011 to prevent excessive condensed water between the two straight-section heat exchangers 201 .

[0108] In some specific embodiments of the present invention, the dimension of the drain port 3016 in the third direction is L3, and L3 satisfies the relationship: 4.5 mm≤L3≤5.5 mm.

[0109] In some embodiments of the present application, the size of the drain port 3016 in the third direction is L3, L3 ≤ 5.5 mm.

[0110] The size of the drain port 3016 in the third direction cannot be too large. If it is too large, the heat exchange airflow between the two straight heat exchangers 201 will be lost too much, which will affect the air supply volume of the air duct machine 100 and reduce the user experience. In order to prevent the heat exchange airflow between the two straight heat exchangers 201 from being lost too much, the size of the drain port 3016 in the third direction is set not to exceed the seventh parameter value. For example, the seventh parameter value can be 5.5mm, 5.4mm, or 5.3mm. Consider selecting a suitable and specific parameter in the specific design.

[0111] In some embodiments of the present application, a dimension of the drain port 3016 in the third direction is L3, and L3 ≥ 4.5 mm.

[0112] The size of the drain port 3016 in the third direction cannot be too small. If it is too small, it will be difficult for the condensed water between the two straight heat exchangers 201 to enter the water receiving pan body 3011, and it is easy to cause too much condensed water to accumulate between the two straight heat exchangers 201, which will affect the working safety of the heat exchanger 2. In order to prevent too much condensed water from accumulating between the two straight heat exchangers 201, the size of the drain port 3016 in the third direction is set to be not less than the eighth parameter value. For example, the eighth parameter value can be 4.5mm, 4.4mm, or 4.3mm. Consider selecting a suitable and specific parameter in the specific design.

[0113] In some embodiments of the present application, the size of the drain port 3016 in the third direction is L3, 4.5mm≤L3≤5.5mm, which can not only ensure the normal air supply volume of the duct unit 100, but also improve the working safety of the heat exchanger 2.

[0114] In some specific embodiments of the present utility model, an elastic wiring buckle 30112 is provided on the water receiving tray body 3011, and the elastic wiring buckle 30112 is used to constrain the wiring.

[0115] Specifically, in order to meet the wiring requirements of various sensors when the duct unit 100 is inverted, an elastic wiring buckle 30112 is provided on the water receiving tray body 3011. The elastic wiring buckle 30112 has a certain elasticity, which can facilitate the wiring. In addition, the elastic wiring buckle 30112 can squeeze the wiring under the action of its own elasticity, which can prevent the speed limit from escaping.

[0116] In some specific embodiments of the present invention, the elastic wiring buckle 30112 is opened on one side in the second direction to facilitate wiring constraint and wire harness detachment.

[0117] In some specific embodiments of the present invention, the distance between the open side of the elastic wiring buckle 30112 in the second direction and the water receiving tray body 3011 is L4, and L4 satisfies the relationship: 5mm≤L4≤8mm.

[0118] In some embodiments of the present application, the distance between the open side of the elastic wiring buckle 30112 in the second direction and the water receiving tray body 3011 is L4, and L4≤8mm.

[0119] The distance between the open side of the elastic wiring buckle 30112 in the second direction and the water tray body 3011 cannot be too large. If it is too large, it will affect the restraining effect of the elastic wiring buckle 30112 on the wire harness, and the wire harness is easy to fall off. In order to ensure the reliability of the elastic wiring buckle 30112 restraining the wiring, the distance between the open side of the elastic wiring buckle 30112 in the second direction and the water tray body 3011 is set to not exceed the ninth parameter value. For example, the ninth parameter value can be 8mm, 7mm, or 6mm. Consider selecting a suitable and specific parameter in the specific design.

[0120] In some embodiments of the present application, the distance between the open side of the elastic wiring buckle 30112 in the second direction and the water receiving tray body 3011 is L4, and L4≥5mm.

[0121] The distance between the open side of the elastic wiring buckle 30112 in the second direction and the water tray body 3011 cannot be too small. If it is too small, the wiring harness will not be easy to match with the elastic wiring buckle 30112, increasing the difficulty of installation. To ensure the convenience of wiring installation, the distance between the open side of the elastic wiring buckle 30112 in the second direction and the water tray body 3011 is set to be not less than the tenth parameter value. For example, the tenth parameter value can be 5mm, 6mm, or 7mm. Consider selecting a suitable and specific parameter in the specific design.

[0122] In some embodiments of the present application, the distance between the open side of the elastic wiring buckle 30112 in the second direction and the water tray body 3011 is L4, 5mm≤L4≤8mm, which not only ensures the reliability of the elastic wiring buckle 30112 in constraining the wiring, but also facilitates the installation and coordination of the wiring harness and the elastic wiring buckle 30112, thereby reducing the difficulty of installation.

[0123] In some specific embodiments of the present invention, Figure 5 , Fig.10 and Fig.11 As shown, the water tray body 3011 is L-shaped and includes a first body portion 30113 and a second body portion 30114 . The first body portion 30113 is located on the side of the heat exchanger 2 facing the air inlet, and the cover plate 3012 is connected to the first body portion 30113 .

[0124] In the L-shaped water receiving tray body 3011, the first main body part 30113 is used to receive the condensed water falling from the heat exchanger 2, the cover plate 3012 is connected to the side of the first main body part 30113 away from the heat exchanger 2 in the first direction, and together with the first main body part 30113 defines a receiving groove 3013, and the insulation component 302 is arranged in the receiving groove 3013.

[0125] Furthermore, in an embodiment of the present invention, the cover plate 3012 can be used as an auxiliary water receiving tray, which has the ability to store a certain amount of condensed water.

[0126] The second main body portion 30114 is connected to one end of the first main body portion 30113 in the second direction. The second main body portion 30114 is bent and extended relative to the first main body portion 30113 toward the first direction close to the heat exchanger 2, so that the first main body portion 30113 and the second main body portion 30114 form an L-shaped structure of the water receiving tray body 3011. In this way, the water receiving tray body 3011 of the embodiment of the utility model can be suitable for different installation directions of the duct machine 100, such as vertical, inverted and horizontal.

[0127] The second main body 30114 and the heat exchanger 2 are spaced apart from each other in the second direction, so that the second main body 30114 can avoid the straight section heat exchanger 201 in the embodiment of the utility model, thereby ensuring the working reliability of the straight section heat exchanger 201.

[0128] The first body part 30113 and the second body part 30114 are integrally formed structural parts, which can simplify the structure of the water receiving tray body 3011, thereby reducing the assembly links of the first body part 30113 and the second body part 30114. In addition, during the production process, the first body part 30113 and the second body part 30114 can be integrally formed, thereby improving the production efficiency of the water receiving tray body 3011.

[0129] like Figure 1 As shown, the air duct machine 100 according to the embodiment of the utility model includes a casing 1, a heat exchanger 2, a fan assembly 4 and a water receiving tray assembly 3.

[0130] The casing 1 is used to be placed vertically on the ground, and the casing 1 is provided with an air inlet and an air outlet, the heat exchanger 2 is arranged in the casing 1, the fan assembly 4 is arranged in the casing 1 and is located on one side of the heat exchanger 2, the fan assembly 4 drives the air to enter the casing 1 from the air inlet, and the air exchanges heat with the heat exchanger 2 to form a heat exchange airflow, and then is driven by the fan assembly 4 to enter the room from the air outlet.

[0131] The casing 1 may have multiple air inlets, for example, one air inlet may be an air inlet for outdoor fresh air, and another air inlet may be an air inlet for indoor air. In addition, the fan assembly 4 may be located on one side of the heat exchanger 2 adjacent to the air outlet.

[0132] In this way, the duct machine 100 can selectively control outdoor fresh air and indoor air to enter the casing 1 through the air inlets through multiple air inlets, and the outdoor fresh air or indoor air can form a heat exchange airflow after heat exchange with the heat exchanger 2, and then be driven by the fan assembly 4 to be introduced into the room from the air outlet, thereby realizing indoor cooling or heating.

[0133] The water tray assembly 3 is arranged at the air inlet and is located on one side of the heat exchanger 2. This not only improves the integration of the internal structure of the air duct machine 100, which is conducive to reducing the size of the air duct machine 100, but also ensures that the air enters the casing 1 normally from the air inlet to ensure the formation of heat exchange airflow in the air duct machine 100.

[0134] It can be understood that the water tray assembly 3 is used to receive the condensed water falling from the surface of the heat exchanger 2. Such a configuration can, on the one hand, prevent the condensed water from flowing out of the duct machine 100 and affecting the environment, and on the other hand, collect the condensed water so that it can be reused.

[0135] The water receiving tray assembly 3 includes a water receiving tray component 301 and a heat-insulating component 302. The heat-insulating component 302 is arranged in the water receiving tray component 301, and the water receiving tray component 301 can be insulated during the operation of the air duct machine 100. This can reduce the condensed water in the water receiving tray from absorbing the heat of the surrounding air, avoid condensation caused by the cold air outside the water receiving tray, and prevent the condensed water from falling from the water receiving tray, thereby improving the safety of the air duct machine 100.

[0136] In the embodiment of the utility model, the water receiving pan body 3011 can not only be used to receive the condensed water dropped from the heat exchanger 2 , but also provide a setting space for the heat insulation component 302 .

[0137] It should be noted that, in the embodiment of the present utility model, the condensed water on the heat exchanger 2 falls into the water receiving tray assembly 3 along the first direction under the action of gravity.

[0138] Combination Figure 3 As shown, a receiving groove 3013 is provided inside the water receiving tray 301 , and the heat-insulating component 302 can be disposed in the receiving groove 3013 .

[0139] In this way, the heat preservation member 302 can be arranged inside the water receiving tray 301, which can ensure the structural reliability of the heat preservation member 302 in the water receiving tray assembly 3. In this way, during the production process of the air duct machine 100, the fixing operation of the heat preservation member 302 can be reduced, which is conducive to simplifying the production of the air duct machine 100.

[0140] Furthermore, the insulation component 302 is arranged inside the water receiving tray 301, so that the insulation component 302 can insulate the condensed water received by the water receiving tray 301, thereby preventing the condensed water in the water receiving tray 301 from absorbing heat from the surrounding air, and can effectively reduce the generation of condensation on the outside of the water receiving tray assembly 3, thereby effectively improving the safety of the duct machine 100.

[0141] Other structures and operations of the duct machine 100 according to the embodiment of the utility model are known to ordinary technicians in this field and will not be described in detail here.

[0142] The duct air conditioner 100 of the present invention performs a refrigeration cycle of the duct air conditioner 100 by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0143] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0144] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air duct unit 100 can adjust the temperature and humidity of the indoor space.

[0145] In the description of this specification, the description with reference to the terms "specific embodiment", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0146] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
