The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

An air duct machine 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

An air duct machine 100 according to an embodiment of the present invention, as shown in fig. 1 to 3, includes: the indoor heat exchange assembly 2, the indoor fan assembly 3, the steam pipe 4 and the muffler 5 are all arranged in the shell 1, and the shell 1 is provided with the indoor heat exchange assembly 2, the indoor fan assembly 3, the steam pipe 4 and the muffler 5. The casing 1 is provided with an air inlet 11 and an air outlet 12, and when the indoor fan assembly 3 operates, driving air flow is blown to the air outlet 12 from the air inlet 11 through the indoor heat exchange assembly 2. The air duct machine 100 is an indoor unit of a so-called central air conditioner, and the air duct machine 100 exchanges heat with indoor air through the indoor heat exchange unit 2, thereby refrigerating or heating an indoor environment.

Specifically, the steam pipe 4 is connected to an external steam generator through a steam input pipe 40, the steam input pipe 40 is extended from the inside of the cabinet 1, and the steam generator is provided outside the ducted air conditioner 100. The steam pipe 4 is provided with a steam nozzle 41, and the steam nozzle 41 is used for jetting steam to the air flow flowing towards the air outlet 12, so that the air blown to the indoor environment can be humidified when the steam pipe 4 works. The muffler 5 is connected to the steam pipe 4, and the muffler 5 is used for reducing noise of the steam.

It will be appreciated that because the space in which the ducted air machine 100 is to exchange heat is typically large, the steam generation requirements of the steam generator operating in conjunction with the ducted air machine 100 are very high. For example, when the ductwork 100 is installed in an airport, restaurant, mall, etc., one ductwork 100 may require space heat exchange for tens or even hundreds of cubic meters. Even if the air duct machine 100 is installed in a house of a common resident, the expected values of the air duct machine 100 and other air conditioners are different, and the air duct machine 100 has stronger heat exchange capability than other air conditioners, so that all corners of the house can be refrigerated or heated well. Therefore, when the humidification function is configured on the air-duct machine 100, the amount of moisture that the air-duct machine 100 can output also needs to be adapted to the humidification space requirement. This function is equivalent to a failure if the ducted air machine 100 is requiring a large amount of steam and the steam generator is not available.

It is because the amount of steam required by the ductwork 100 during humidification is excessive, which can cause problems for the proper use of the ductwork 100. These problems are not generally found in other types of air conditioners because the other types of air conditioners need to face a small heat exchange space, the amount of steam required is small, and the problems are difficult to find in the case of a small amount of steam.

Specifically, when the ducted air conditioner 100 is turned on for humidification, the steam generator may deliver a large amount of steam to the steam duct 4, and the steam is ejected through the steam nozzle 41 of the steam duct 4, so that the humidity of the air blown to the indoor environment is greatly increased.

Because there is a pressure difference when the steam enters the inner machine from the outer machine, there is a noise such as "pop, pop" of the steam scouring sound such as "click, click" of the water drop sound, etc. when the steam enters the steam pipe 4 from the steam input pipe 40, and the noise is larger as the steam amount is larger. These sounds are different from the buzzing of the airflow blowing, and easily cause the illusion of water leakage or air valve breakage to the person hearing. Therefore, the muffler 5 is arranged on the steam pipe 4, so that abnormal sound of steam can be reduced, and the quality experience of the air duct machine 100 with the humidifying function can be greatly improved.

In some embodiments, as shown in fig. 1, the casing 1 is provided with hanging lugs 13, and the hanging lugs 13 are used for hanging, that is, the air duct machine 100 is hung on a roof through the hanging lugs 13, so that the air duct machine 100 supplies air for a longer distance.

Optionally, the casing 1 is cuboid, and the overall dimension is shortest in the height direction, that is, the casing 1 is flat, so as to reduce the occupied height. In some examples, the casing 1 may be cylindrical, and the axis of the cylinder may be disposed in the up-down direction, and the shape of the casing 1 is not limited herein.

The casing 1 is provided with an air inlet 11 for blowing air flow and an air outlet 12 for blowing air flow, and in the example of fig. 3, the air inlet 11 and the air outlet 12 are respectively arranged at the front side and the rear side of the casing 1. In other examples, the air inlet 11 and the air outlet 12 are provided in various positions, for example, in examples, the air outlet 12 is provided around the casing 1, the air inlet 11 is provided at the bottom of the casing 1, and in still other examples, the air inlet 11 and the air outlet 12 are provided with air guiding pipes, respectively, so that after the air duct machine 100 is installed, the air inlet position and the air outlet position are not limited by the installation position of the casing 1 of the air duct machine 100.

In some embodiments, as shown in fig. 3, indoor fan assembly 3 includes wind wheel 31 and motor 32, and wind wheel 31 is various in type, wind wheel 31 in fig. 3 is a centrifugal wind wheel, and wind wheel 31 in other examples may be a cross-flow wind wheel, an oblique-flow wind wheel, or the like. In the example of fig. 3, there are two wind wheels 31, and the motor shaft of the motor 32 is connected to both wind wheels 31 at the same time to increase the air flow and expand the heat exchange efficiency.

In some embodiments, the evaporator of the indoor heat exchange assembly 2 has various shapes, in the example of fig. 4, the evaporator has a V shape, in some examples, the evaporator has a straight plate shape, and in other examples, the evaporator is folded three or four sections, which is not limited herein.

In the embodiment of the present invention, the indoor heat exchange assembly 2 and the indoor fan assembly 3 may be variously arranged. For example, in the examples of fig. 3 and 4, the indoor fan assembly 3 is disposed on a horizontal side of the indoor heat exchange assembly 2. In some examples, the indoor heat exchange assembly 2 is arranged around the indoor fan assembly 3, and after the indoor fan assembly 3 enters air from the bottom, the air is blown out towards the periphery, so that the periphery of the indoor heat exchange assembly 2 can be subjected to heat exchange caused by strong air convection.

Specifically, as shown in fig. 4, the air duct machine 100 further includes a water pan 6 disposed below the indoor heat exchange assembly 2, and the water pan 6 is used for receiving condensed water flowing down from the indoor heat exchange assembly 2. More specifically, the water receiving tray 6 has a water outlet pipe 61 penetrating the casing 1, and the water outlet pipe 61 discharges the condensed water collected by the water receiving tray 6 to the outside, for example, to the outside, or to a sewer or a pool, so as to avoid the condensed water from overflowing directly from the gap of the casing 1.

Specifically, as shown in fig. 1, the indoor heat exchange unit 2 has a refrigerant pipe 20 for passing in and out a refrigerant, and the refrigerant pipe 20 is disposed on the casing 1 in a penetrating manner. Here, the refrigerant pipe 20 is connected to the outdoor unit, and two refrigerant pipes 20 are provided for inflow and outflow of the refrigerant, respectively.

In some embodiments, the steam pipe 4 is located between the indoor heat exchange assembly 2 and the indoor fan assembly 3, and the air flow passes through the indoor heat exchange assembly 2 after exiting from the indoor fan assembly 3 and then enters the room. In this embodiment, the shape of the steam pipe 4 matches its position.

In some embodiments, as shown in fig. 3 and 4, the indoor fan assembly 3 is disposed at a horizontal side of the indoor heat exchange assembly 2, and the steam pipe 4 is disposed therebetween in a horizontal direction. In particular, the steam pipe 4 may be formed in a straight pipe shape, which not only facilitates the processing, but also prevents the steam pipe 4 from excessively obstructing the air flow. In other examples, for example, when the indoor heat exchange assembly 2 is disposed around the indoor fan assembly 3, the steam pipe 4 may be formed into a ring shape (e.g., circular or square shape), so that the airflow blown around can be humidified.

More specifically, as shown in fig. 5 and 6, the muffler 5 is provided between the steam pipe 4 and the steam input pipe 40, so that the muffler 5 reduces noise from the source of the steam pipe 4 to thereby improve the noise reduction effect. Of course, the location of the muffler 5 in the embodiment of the present invention is not limited thereto, and for example, in other examples, the muffler 5 may be directly covered outside the steam pipe 4, so as to reduce noise of the air flow passing through. In still another example, the number of the muffler 5 is plural, and the plural muffler 5 is provided in the steam pipe 4 at a distance from each other, and performs local noise reduction at plural places on the steam pipe 4.

In some alternative embodiments, as shown in fig. 5, the muffler 5 is disposed along the length of the steam pipe 4, i.e., the length of the muffler 5 coincides with the length of the steam pipe 4, which is advantageous in reducing the resistance of the muffler 5 to the airflow.

Specifically, the muffler 5 is cylindrical, the steam pipe 4 is a circular straight pipe, and the axis of the muffler 5 is parallel to the axis of the steam pipe 4. The cylindrical muffler 5 is not only convenient to seal, but also the reflected wave of sound by the circle is concentrated at the center of the circle, so that the noise is reduced by the mutual cancellation of the waves.

In some embodiments, the lowest part of the muffler 5 is connected to the steam pipe 4 to lead out condensed water to the steam pipe 4, so that water in the muffler 5 can be avoided, and the volume is prevented from being influenced by excessive water.

Specifically, the vapor tube 4 is provided with a water outlet hole 42, and the condensed water in the vapor tube 4 and the condensed water flowing in from the muffler 5 are discharged from the water outlet hole 42.

In the embodiment of the present invention, the muffler 5 has various structural forms. For example, the muffler 5 has only one housing, so that the high-pressure gas is discharged by increasing the space after entering the muffler 5, so that the steam again flows to the steam pipe 4 without generating excessive noise. For another example, in order to improve the noise reduction effect, a noise reduction material is disposed in the muffler 5, for example, noise reduction balls or noise reduction nets are filled in the muffler 5, in some examples, noise reduction wires are filled in the muffler 5, the noise reduction wires are irregularly wound in the noise reduction cavity 50, when steam is filled in the noise reduction cavity 50, the noise reduction wires are driven to vibrate by the air flow, so that energy of the air flow is consumed, and in particular, the air flow can flow smoothly, and noise is reduced.

In some embodiments, a baffle 53 is disposed in the muffler 5 to divide the interior of the muffler 5 into a plurality of muffling chambers 50, and a through hole 54 is disposed on the baffle 53. The provision of multiple sound deadening chambers 50 may allow for multiple layers of pressure relief, thereby further reducing noise. For a plurality of silencing chambers 50, various silencing schemes may be designed, for example, various silencing materials are filled in each silencing chamber 50 by utilizing the characteristic that the air pressure of each silencing chamber 50 decreases. For example, the silencing chamber 50 connected to the steam inlet pipe 40 is filled with a silencing material, and the other silencing chambers 50 are designed as cavities.

Specifically, the baffle 53 is disposed vertically, with the bottom of the baffle 53 being spaced apart from the bottom wall of the muffler 5 to define the through-air hole 54. The air passing holes 54 can not only pass through steam, but also enable condensed water to flow through, so that the condensed water in the muffler 5 can be conveniently emptied.

In other examples, the baffle 53 is provided with a plurality of small holes, and the airflow is utilized to drive the vibration of the baffle 53 to reduce the flow velocity and noise during the hole passing. Of course, in other embodiments of the present invention, the baffle 53 may also separate the muffler 5 into a circuitous flow path, or the baffle 53 may be designed in other ways, which are not limited herein.

Further, as shown in fig. 6, the muffler 5 is provided with an inner convex ring 55, thereby facilitating positioning of the baffle 53. Wherein, the baffle plate 53 is located at one side of the inner convex ring 55 facing the steam input pipe 40, so that the baffle plate 53 and the inner convex ring 55 are pressed more tightly by the filled steam, thereby avoiding the skew of the baffle plate 53.

Specifically, the inner convex ring 55 is formed by recessing the peripheral wall of the muffler 5 inward, and the inner convex ring 55 is a circular ring shape, thereby facilitating processing.

In the example of fig. 6, the interior of the muffler 5 is divided into a first silencing cavity 51 and a second silencing cavity 52 by a baffle 53, the first silencing cavity 51 is connected with the steam input pipe 40, the second silencing cavity 52 is connected with the steam pipe 4, steel wires are arranged in the first silencing cavity 51, and the second silencing cavity 52 is a cavity.

Further, the connection of the steam input pipe 40 and the muffler 5 is higher than the bottom end of the muffler chamber 50, so that the backflow of condensed water, that is, the condensed water flowing along the steam input pipe 40 to the outside of the cabinet 1, can be prevented.

In some embodiments, as shown in fig. 5 and 4, the steam pipe 4 is provided with a condensed water guide structure 43 for guiding out condensed water to the indoor heat exchange assembly 2. Here, since the temperature of the condensed water is generally high, it may reach 80-90 degrees, and if the condensed water in the steam pipe 4 drops directly downward, the parts falling to the condensed water of high temperature are easily damaged. And the condensed water guiding structure 43 is arranged to guide the high-temperature condensed water to the indoor heat exchange assembly 2, so that the harm of the high-temperature condensed water can be reduced by utilizing the heat exchange characteristic of the indoor heat exchange assembly 2.

Specifically, when the ducted air conditioner 100 is in a heating state, that is, the indoor heat exchange assembly 2 releases heat to the air flowing therethrough, the high-temperature condensed water absorbs heat when flowing to the indoor heat exchange assembly 2. Because the temperature of the high-temperature condensed water is higher, the high-temperature condensed water can be quickly evaporated into steam, and the further humidifying effect is achieved. When the air duct machine 100 is in a refrigerating state, that is, the indoor heat exchange assembly 2 releases cold energy to air flowing through, the high-temperature condensed water can absorb the cold energy and rapidly cool down when flowing to the indoor heat exchange assembly 2. The cooled condensed water drops onto other parts, so that the parts are not easy to scald.

Specifically, as shown in fig. 6, the bottom of the steam pipe 4 is provided with a water outlet hole 42, and a condensed water guide structure 43 is connected to the bottom of the steam pipe 4 to receive water from the water outlet hole 42. As shown in fig. 5 and 4, the condensed water guide structure 43 is provided to extend obliquely toward the indoor heat exchange assembly 2 in a downward direction, so that the condensed water flows downward in accordance with the action of gravity and also in accordance with the flow force of the air flow, so that the condensed water can flow toward the indoor heat exchange assembly 2 more effectively.

In the example of fig. 5, a row of steam nozzles 41 are provided on the steam pipe 5 to disperse steam so that the air flow can be uniformly humidified. The steam pipe 5 is provided with two water outlet holes 42, and the bottom of the steam pipe 5 is provided with a condensed water guiding structure 43 corresponding to each water outlet hole 42. Each condensate guiding structure 43 resembles a shape of a slide, guiding condensate downwards. The condensed water guide structure 43 has a U-shape with an upward opening in cross section, and both sides thereof can block the impact of air flow. In this example, each condensate guiding structure 43 is substantially equal to the diameter of the steam pipe 4, which is arranged to avoid causing excessive wind resistance to cause noise.

In some embodiments, as shown in fig. 2, the steam pipe 4 and the muffler 5 are erected within the cabinet 1 by a support structure 44, and as shown in fig. 5, the support structure 44 includes a plurality of support plates 440 disposed at intervals. This enables the steam pipe 4 and the muffler 5 to be firmly disposed in the casing 1, avoiding blow-off and blow-off.

Specifically, as shown in fig. 5, each support plate 440 is bent into a plurality of segments, each segment participating in a different function. More specifically, each of the support plates 440 includes a first flap 441 and a second flap 442, the first flap 441 is provided with a connection hole 443 for connecting a screw, the second flap 442 is vertically disposed and the upper rim is provided with a support half hole 444, and the steam pipe 4 and the muffler 5 are seated in the support half hole 444. The first flap 441 is thus screwed to the adjacent part, while the second flap 442 supports the steam pipe 4 and the muffler 5, making the support more stable by the weight of the steam pipe 4 and the muffler 5. It should be noted that a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

Alternatively, as shown in fig. 5, the support structure 44 is provided with a total of three support plates 440, one of which is supported below the steam pipe 4 and the other of which is supported below the muffler 5. A support plate 440 is also attached to the end face of the muffler 5 to enhance the support.

Specifically, the supporting plate 440 is welded with the steam pipe 4, and the supporting plate 440 is welded with the muffler 5, so that the connection reliability is improved.

Further, the second folding plate 442 is aligned with the airflow direction, such as the airflow flowing from back to front in fig. 4, and the second folding plate 442 is parallel to the front-back direction, so that the wind resistance can be further reduced.

In some embodiments, as shown in fig. 1, the steam input tube 40 and the refrigerant tube 20 are located on the same side wall of the casing 1. Thus, the device is convenient to overhaul, install and maintain. Further, as shown in fig. 1, the water outlet pipe 61 and the refrigerant pipe 20 are located on the same side wall of the casing 1, which is further convenient for maintenance.
