The utility model provides a vertical air conditioner indoor unit. An indoor unit of an upright air conditioner is an indoor part of the air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a schematic structural view of a floor type air conditioning indoor unit according to an embodiment of the present invention.

As shown in fig. 1, the indoor unit of a floor air conditioner according to an embodiment of the present invention may generally include a casing 10, a plurality of fans 80, and a plurality of

air guides

61 and 62.

The casing 10 is provided with an air supply outlet 12, a plurality of air ducts 20 are formed in the casing 10 side by side, and outlets of the plurality of air ducts 20 are communicated with the same air supply outlet 12 to supply air to the indoor environment through the air supply outlet 12. Of course, the casing 10 may have other air supply ports. The casing 10 of the present embodiment includes a framework for forming a basic frame of the indoor unit, and body components such as a volute 21 and a volute tongue 22 for defining an air duct 20. The blowing port 12 is used to blow a conditioned air flow in the casing 10 toward the room to condition the indoor air. The adjusting air flow can be cold air produced by the indoor unit of the vertical air conditioner in a refrigeration mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode, and the like.

An air inlet (not shown) may be formed on the cabinet 10, and the air inlet may be formed at a rear surface of the cabinet 10 for introducing indoor air flow. In some embodiments, the indoor unit of the stand type air conditioner may be an indoor unit of an air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system, in which the heat exchanger 40 is disposed. Indoor air enters the casing 10 through the air inlet, exchanges heat with the heat exchanger 40, enters the air duct 20 under the action of the fan 80, and is blown to the indoor environment through the air supply outlet 12 to regulate the indoor environment air.

Each fan 80 is disposed in one of the air ducts 20, and the function of the fan 80 is to promote the airflow in the casing 10 to flow into the air duct 20 and then blow the airflow to the indoor environment through the supply outlet 12. A plurality of air guides 61, 62 are provided at the supply port 12 for guiding the wind direction, each

air guide

61, 62 being independently controlled and corresponding to the outlet of one air duct 20. That is, the air guiding directions of the

air guiding devices

61 and 62 are not mutually affected, and the air flow in the covered area can be guided independently. It will be appreciated that the operation of the two blowers 80 is also independently controlled, and that it is possible to choose to turn on only one blower 80, or to turn on both blowers 80 simultaneously. The speed of each fan 80 is also independently controlled. The power rating of each fan 80 may be the same or different.

As shown in fig. 1, the casing 10 may extend in a vertical column shape, that is, the casing 10 is a long strip extending in the up-down direction. Fig. 1 is a cross-sectional view schematically showing an indoor unit of an upright air conditioner taken in a horizontal plane. The air duct 20 and the air supply port 12 may be formed in a long shape extending in the vertical direction. The fan 80 is preferably a crossflow fan with its axis extending vertically. In alternative embodiments, the shape of the air supply opening 12 may be other shapes, and accordingly, the fan 80 may be other types of fans such as an axial flow fan, a centrifugal fan, and the like. The air duct 20, the shape of the air supply opening, and the fan pattern are not particularly limited in the present invention.

In the vertical air conditioner indoor unit of the embodiment of the utility model, the outlets of the plurality of air channels 20 are communicated with the same air supply outlet 12, so that the outlet air flows of the air channels 20 can be converged at the air supply outlet 12, pressure difference is formed at the air supply outlet 12 when one air channel 20 supplies air, the flow of the air flows of the adjacent air channels 20 is promoted by drainage, and the outlet air flows of the adjacent air channels 20 form a mutual promotion effect, so that the wind power is stronger, the ultra-strong air supply with large air volume can be realized, and the requirement of a large living room of a user on the large air volume can be met. In addition, because a plurality of independently controlled

air guide devices

61 and 62 are arranged, the

air guide devices

61 and 62 can guide air in a plurality of directions to enlarge the whole air supply range, and the

air guide devices

61 and 62 can guide air in the same direction, so that a plurality of air flows are converged and promoted, the wind power is stronger, and a certain indoor area can be blown with pertinence.

fig. 3 is a schematic view of the indoor unit of the floor air conditioner shown in fig. 1 when two air guide devices guide air to the left; fig. 4 is a schematic view of the indoor unit of the floor air conditioner shown in fig. 1 when both air guide devices guide air to the right; fig. 5 is a schematic view of the indoor unit of the floor air conditioner shown in fig. 1, in which the left air guide device guides air to the left and the right air guide device guides air to the front; fig. 6 is a schematic view of the indoor unit of the floor air conditioner shown in fig. 1, in which the left air guide device guides air to the left and the right air guide device guides air to the right; fig. 7 is a schematic view of the floor air conditioning indoor unit shown in fig. 1, in which the left air guide device guides air to the left and the right air guide device is in a closed state.

For example, as shown in fig. 1 to 7, in some embodiments, the supply opening 12 is opened forward, and the number of the wind tunnels 20 is two, which are arranged side by side in the lateral direction of the cabinet 10. The number of fans 80 and air guides 61, 62 is also two.

The wind direction of the whole air blowing opening 12 can be made the same, so that the two air flows blown by the two air ducts 20 can be mutually promoted after being converged, the wind force can be stronger, and a certain area in a room can be purposefully blown. For example, as shown in fig. 2, both

air guiding devices

61 and 62 guide air forward. Alternatively, both the

air guide devices

61 and 62 are directed to the left as shown in fig. 3, or both the

air guide devices

61 and 62 are directed to the right as shown in fig. 4.

Alternatively, the air guide directions of the two

air guide devices

61 and 62 may be different, and the entire air blowing range may be expanded. For example, as shown in fig. 5, the left air guide device 61 may guide air to the left, and the right air guide device 62 may guide air to the front. Alternatively, as shown in fig. 6, the left air guide device 61 is directed to the left, and the right air guide device 62 is directed to the right.

Further, the air guides 61 and 62 may be configured to shield the outlet of the air duct 20. For example, as shown in fig. 7, one air guide device 61 is used to guide air, and the other air guide device 62 is used in a closed state. Of course, the fan 80 corresponding to the air guide device 62 in the closed state is also preferably in the closed state.

Of course, the air supply modes of the indoor unit of a floor air conditioner according to the present invention are described by way of example only in fig. 1 to 7, but the present invention is not exhaustive, and there are many other air supply modes of the indoor unit of a floor air conditioner according to the present invention, which are not listed here.

In some embodiments, as shown in fig. 1 to 7, each

air guiding device

61, 62 includes a plurality of swinging blades, and each swinging blade of each

air guiding device

61, 62 is configured to synchronously and rotatably adjust the lateral air outlet direction of the air outlet 12. Specifically, each swing blade is in a strip plate shape extending along the vertical direction, the rotation axis of each swing blade is parallel to the vertical direction, linkage can be achieved among the swing blades through a linkage mechanism, and synchronous rotation is achieved under the driving of a motor. Such a linkage mechanism with a plurality of swing vanes is widely used in the air conditioning field and will not be described in detail here. When the plurality of swing vanes rotate to the coplanar state, they can shield the air supply opening 12.

In some alternative embodiments, the

wind guiding devices

61, 62 may be a single rotatable strip-shaped wind guiding plate extending vertically, and will not be described in detail.

Further, the floor air conditioning indoor unit preferably further includes an intermediate swing vane 63 that is positioned between the two

air guiding devices

61 and 62 and is arranged to be swingable laterally on both sides so as to guide the wind direction together with the

air guiding devices

61 and 62. The intermediate swing blade 63 is driven by an independent motor and is not affected by the two

air guiding devices

61 and 62.

For example, as shown in fig. 1, when the flaps of the

air guiding devices

61 and 62 on both sides are in the coplanar state, the middle flap 63 is also in the coplanar state with the flaps on both sides, so as to close the air outlet 12 together. As shown in fig. 2 to 4, when the two side blades swing wind in the same direction, the swing angle of the middle blade 63 is made to be the same as that of the two side blades to assist the two side blades to swing wind together. As shown in fig. 5 and 6, when the air guide directions of the left and right flaps are different, the intermediate flap 63 can be held at an intermediate position (a position extending forward and backward) to separate the air flows on the left and right sides and prevent the air flows from affecting each other. The arrangement of the middle swinging vane 63 strongly assists the two

air guide devices

61 and 62, and the effect is very ingenious.

In some embodiments, referring to fig. 1, for a solution in which the number of the wind tunnel 20 is two, inlets of the two wind tunnels 20 may be opened toward a lateral center of the cabinet 10, and the opening direction is inclined toward the rear. And the two fans 80 are respectively located at the inlets of the two air ducts 20 and are oppositely arranged. In the direction from the upstream to the downstream of the air ducts 20, the distance between the two air ducts 20 gradually increases and then gradually decreases to lead to the same air outlet 12. In this way, on the one hand, the width of the casing 10 can be utilized more efficiently, and a high efficiency volute shape required for the air duct 20 can be formed. On the other hand, the outlet airflow of each air duct 20 is also deflected toward the other air duct 20 (the outlet airflow of the left air duct 20 is deflected toward the right, and the outlet airflow of the right air duct 20 is deflected toward the left), so that the two airflows can impact each other at the air supply opening 12, and the interaction promotion effect of the outlet airflows of the two air ducts 20 is stronger.

Specifically, as shown in FIG. 1, each air chute 20 is defined by a volute 21 and a volute tongue 22. The two volute tongues 22 are adjacent to each other, and the distance between the two volute tongues 22 gradually increases and then gradually decreases in the direction from the upstream to the downstream of the air duct 20. The two volutes 21 are located at the lateral outer sides of the two volute tongues 22 (i.e. the volute 21 of the left air duct 20 is located at the left side of the volute tongue 22, and the volute 21 of the right air duct 20 is located at the right side of the volute tongue 22), and both the two volutes 21 are curved and the concave sides of the two volutes face each other. Thus, a highly efficient volute is formed, and the distance between the two air ducts 20 is gradually increased and then gradually decreased in the direction from the upstream to the downstream of the air ducts 20.

The outlet ends (A, B) of the two volutes 21 respectively form two ends of the air supply opening 12, and the outlet ends (C ends) of the two volute tongues 22 are positioned further back than the outlet end (A, B) of the volute 21. Thus, the outlet airflows of the two air ducts 20 are collected at the air supply opening 12. Preferably, the outlet ends of the two spiral tongues 22 may intersect at the end C, so that the outlets of the two air ducts 20 are closely arranged, and the outlet air flows of the two air ducts 20 are closer to each other, so that the interaction force is stronger. For the embodiment with the intermediate swing blade 63, the intermediate swing blade 63 can be rotatably mounted at the intersection (C end) of the outlet ends of the two volute tongues 22.

As shown in fig. 1, the vertical air-conditioning indoor unit further includes a heat exchanger 40, the heat exchanger 40 is plate-shaped and located behind the two air ducts 20, and two transverse ends of the heat exchanger are bent forward to overlap the outer sides of the two volutes 21. This structure enables the heat exchanger 40 and the two volutes 21 to form an annular structure having only one outlet of the supply outlet 12, which enables the air flow blown out from the air duct 20 to be the heat-exchanged air flow, and thus the cooling/heating efficiency is higher.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model. Accordingly, the scope of the utility model should be understood and interpreted to cover all such other variations or modifications.
