Detailed Description

The present utility model will be further described with reference to specific embodiments and drawings, in which more details are set forth in the following description in order to provide a thorough understanding of the present utility model, but it will be apparent that the present utility model can be embodied in many other forms than described herein, and that those skilled in the art may make similar generalizations and deductions depending on the actual application without departing from the spirit of the present utility model, and therefore should not be construed to limit the scope of the present utility model in terms of the content of this specific embodiment.

In the following description, the terms "top", "bottom", "upper" and "lower" refer to positions with reference to the conventional mounting position of the ducted air machine, "longitudinal" refer to the direction of the short side of the rectangular plane of the ducted air machine shown in fig. 3, and "transverse" refer to the direction of the long side of the rectangular plane of the ducted air machine shown in fig. 3, unless otherwise specified.

Fig. 1 and 2 are perspective views showing an air duct machine according to a preferred embodiment of the present utility model, wherein fig. 2 is a view showing an internal structure with a portion of a housing 11 removed, and fig. 3 is a plan view showing the air duct machine. As shown in fig. 1 and 2, the ducted air conditioner includes a main body 10, and an outer contour of a housing 11 of the main body 10 has a rectangular cubic shape. Specifically, the body 10 has a top, a bottom, and four peripheral sides extending from the top to the bottom. In a preferred embodiment, one of the two longer opposite sides forms a main air inlet and the other forms a main air outlet, and air flow enters the interior of the air duct machine through the main air inlet and leaves the air duct machine through the main air outlet after heat exchange.

As shown in fig. 3, the main body 10 of the ducted air conditioner mainly includes two parts: a fan section 30 and a heat exchange section 20. A main partition 12 is generally provided between the fan section 30 and the heat exchange section 20, that is, the main partition 12 extends from one short side portion to the other short side portion in the lateral direction of the main body 10, is fixed to the housing 11 of the ducted air conditioner by a fastener, the main partition 12 partitions the inner space of the main body 10 of the ducted air conditioner into two portions, and preferably, the main partition 12 is substantially parallel to the front and rear long side portions.

The fan section 30 mainly includes a fan assembly having one or more fans and a fan motor, and the fan section is further formed with a fan outlet for letting air flow out of the fan section 30 into the heat exchanging section 20. As shown in fig. 2, a plurality of fan outlets 38 are arranged on the main partition 12, each fan outlet 38 corresponding to one fan 31. In the preferred embodiment, six fan outlets 38 are formed in the main partition 12, corresponding to 6 fans 31 respectively. The fan outlets 38 are in the same plane, i.e. in the plane of the main partition 12.

In alternative embodiments, the fan outlet may be formed by the volute of the fan. For example, a through hole is formed in the main partition 12, and an outlet portion of the fan volute extends through the through hole in the main partition 12, and at this time, the outlet portion of the fan volute forms a fan outlet of the fan section 30.

The upper part of the ducted air conditioner shown in fig. 3 is a heat exchanging part 20. The heat exchange portion 20 is mainly provided with a heat exchanger main body 21, a connection pipe 22, a functional component 23, and a drain pan 50 (shown in fig. 2) below the heat exchanger main body 21.

The heat exchanger body 21 is arranged substantially transversely to the main body 10 of the ducted air machine, the heat exchanger body 21 being generally fixed in the heat exchanging section 20 by fixing members from both sides thereof. The lower side edge of the heat exchanger body 21 is abutted against the drain pan 50, and water condensed on the heat exchanger body 21 is collected by the drain pan 50 and guided to be discharged outward.

In particular, the outer diameter Φ of the refrigerant tube of the heat exchanger body 21 according to the present utility model satisfies Φ.ltoreq.5 mm, preferably the outer diameter Φ is 5mm (commonly referred to as Φ5 tube) or 4mm (commonly referred to as Φ4 tube). Such sizing is advantageous in that the size of the heat exchanger main body 21 is reduced by reducing the diameter of the refrigerant pipe, and thus the size of the installation area of the connecting pipe 22 and the functional member 23 can be enlarged without changing the size of the air duct main body 10.

In particular, as shown in fig. 3, the projection of the connection pipe 22 and the functional component 23 on the plane of the fan outlet 38 in the heat exchange portion 20 of the ducted air conditioner does not overlap with the projection of the heat exchanger main body 21 on the plane. In the case where the main partition 12 forms the fan outlets 38, the projection of the connection pipes 22 and 23 on the plane on which the main partition 12 is located does not overlap with the projection of the heat exchanger main body 21 on the plane. That is, the connection pipe 22 and the functional part 23 are entirely disposed outside the side portion of the heat exchanger main body 21, and the entity of the connection pipe 22 and the functional part 23 entirely avoids the main path along which the air flow flows from the fan outlet 38 through the heat exchanger main body 21 to the main body outlet.

In the case where the fan outlets are formed by the fan volutes, the projection of the connection pipes 22 and 23 on the plane on which any one of the fan outlets is located does not overlap with the projection of the heat exchanger main body 21 on the plane.

In this way, any part of the air flow passing through the heat exchanger main body 21 is not blocked by the connecting pipe 22 and the functional member 23, the flow resistance of the air flow is reduced, the air outlet is smoother, and the heat exchanger utilization rate is improved. Another important aspect is that the offset arrangement of the connecting pipe 22 and the functional component 23 in the transverse direction with respect to the heat exchanger body 21 reduces noise while also avoiding problems of condensation water that may occur when the air flow blows onto the connecting pipe and the functional component 23.

In the preferred embodiment, the functional components 23 in the heat exchange portion 20 mainly include an electrically operated valve assembly 25 and a drain component. The electrically operated valve assembly 25 further has a coil portion 251 and a body portion 252, the coil portion 251 and the body portion 252 being integrated together. Wherein, as shown in fig. 5, the outer surface of the body portion 252 is substantially cylindrical, and the electrically operated valve assembly 25 is disposed in the heat exchanging portion 20 such that the central axis of the cylindrical body portion 252 thereof is substantially parallel to the extending direction of the refrigerant tube of the heat exchanger main body 21, i.e., the electrically operated valve assembly 25 is disposed on one side of the heat exchanger main body substantially along the lateral direction of the blower fan.

In order to facilitate the installation of these functional components 23, the heat exchanger 20 is also provided with a support 36, which support 36 extends from one short-side to the other short-side of the ductwork. The support 36 is preferably secured to the housing 11 by fasteners and is preferably made of the same rigid material as the housing 11, such as metal. A mount 361 for fixing the functional part 23 is integrally formed at one side of the support frame 36, for example, the mount 361 is for mounting a drain pump and a float switch. As shown in fig. 1, the support 36 is adjacent to the main body air outlet of the ducted air machine. By providing the support frame, on the one hand, the installation of the fixed functional components is facilitated, and at the same time, the overall structural strength of the main body 10 is also increased.

The lower part shown in fig. 3 is a fan section 30 of an air duct machine, which fan section 30 comprises, in addition to a fan assembly, an electrical box 33 for accommodating control devices and related electrical components. The electrical box 33 and the fan assembly are juxtaposed in the lateral direction of the ducted machine body 10, and the electrical box 33 is adjacent to one short side portion of the body 10.

The fan assembly mainly includes a fan 31 and a fan motor 32. As shown in fig. 2, the fan assembly of the preferred embodiment includes 6 fans 31 and one fan motor 32 for driving the 6 fans 31. The fan motor 32 is provided at a middle position of the 6 fans 31, i.e., three fans 31 are provided at both sides, respectively, thereby providing balanced motor driving force and achieving homogenization of the supply air flow.

In an alternative embodiment, the fan assembly comprises N fans and one fan motor, N being an odd number, in which case the number of fans of the fan motor arranged on the side close to the electrical box is smaller than the number of fans arranged on the side remote from said electrical box. For example, as shown in fig. 6, the fan assembly includes 5 fans and one fan motor 32 'for driving the 5 fans 31'. In this case, 2 fans are arranged between the fan motor 32' and the electrical box 33' on one side of the fan motor 32', and 3 fans are arranged between the fan motor 32' and the side of the housing on the other side of the fan motor 32'. In this way, the length of wiring connected to the electrical box can be reduced.

In addition, as shown in fig. 2, the heat exchanging part 20 of the ducted air conditioner further includes a partition 26, the partition 26 being located at the air flow outflow side of the heat exchanger body 21, the partition 26 being arranged to separate the heat exchanger body 21 from the connection piping 22 and the functional parts 23, and to further concentrate the air flow while reducing noise.

Fig. 4 shows a perspective view of the partition 26. The separator 26 has a generally triangular plate shape with a lower side edge that rests against the drain pan 50 such that the separator 26 lies substantially perpendicular to the plane of the drain pan 50. The baffle 26 has a guide groove 261 provided on a surface thereof, the guide groove 261 extending from top to bottom for guiding condensed water to the drain pan 50. The arrangement of the diversion trench 261 prevents the condensed water at the side part of the heat exchanger main body 21 from directly dripping to the drain pan 50 to generate water dripping sound during the cooling operation of the air duct machine, and further reduces the noise of the air duct machine.

In addition, as shown in FIG. 1, the ducted air machine also includes a cleaning assembly 35. The purge assembly 35 is disposed at or near the body air outlet. Preferably, the purifying component 35 may be a negative ion generator for generating negative ions to flow out of the main body air outlet of the air duct machine along with the air flow, so as to further purify the air flow.

In alternative embodiments, the heat exchange portion 20 of the ducted air machine may include a plurality of heat exchanger bodies, preferably two heat exchanger bodies. The two heat exchanger bodies respectively comprise refrigerant pipes and fins, and the two heat exchanger bodies are arranged back and forth along the air flow direction, namely, the air flow passes through one heat exchanger body and then passes through the other heat exchanger body. Under the control of the control device of the air duct machine, the two heat exchanger main bodies can implement different heat exchange processes in the running process of the air duct machine so as to realize various control modes of the air duct machine.

The refrigerant tubes of the two heat exchanger bodies may have different tube diameters, for example, the refrigerant tube of one heat exchanger body has an outer diameter phi of 5mm (phi 5 tube) and the refrigerant tube of the other heat exchanger body has an outer diameter phi of 4mm (phi 4 tube). The fins of the two heat exchanger bodies may have different pitches. Whereby two heat exchanger bodies of different properties can be provided.

When the heat exchange portion 20 includes a plurality of heat exchanger bodies, the projection of the connection pipe 22 and the functional member 23 of the air duct on the plane on which the fan outlet is located and the projection of the plurality of heat exchanger bodies on the plane do not overlap, so that the air outlet is smooth, and the problem of noise superposition is avoided.

While the utility model has been described in terms of preferred embodiments, it is not intended to be limiting, but rather to the utility model, as will occur to those skilled in the art, without departing from the spirit and scope of the utility model. Therefore, any modification, equivalent variation and modification of the above embodiments according to the technical substance of the present utility model fall within the protection scope defined by the claims of the present utility model.
