Further, the cabinet air-conditioner indoor unit 1 further includes a through air duct 40, a first air blower 21, a second air blower 22, and a heat exchanging device 30.

The through duct 40 communicates the jet air inlet 12 and the first air outlet 13, and penetrates the casing 10 in the front-rear direction.

The cabinet 10 of the indoor unit of the cabinet air conditioner of the present utility model has a conventional air inlet 11 and a first air outlet 13 at the front side of the upper portion of the cabinet 10, and particularly has a second air outlet 14 at the front side of the lower portion of the cabinet 10. Further, the casing 10 is provided therein with not only a conventional first air blower 21 for blowing air to the first air outlet 13, but also a second air blower 22 for blowing air to the second air outlet 14.

When soft refrigeration is needed, the cooling air flow after refrigeration can be mainly blown to the first air outlet 13 by the first air supply fan 21 because of the sinking phenomenon of the cooling capacity.

When soft heating is required, the hot air rises, so the heated hot air can be blown to the second air outlet 14 mainly by the second air blower 22.

Thus, by selectively activating the first air blower 21 and/or the second air blower 22, a plurality of different air blowing modes can be realized, and the multi-purpose different air blowing requirements of users are satisfied.

In addition, the utility model is also provided with the through air duct 40 in particular at the upper part of the casing 10, when the first air supply fan 21 operates, negative pressure is generated in the through air duct 40, under the action of the negative pressure, the ambient air which is not subjected to heat exchange in the ambient space can be caused to enter the through air duct 40 through the jet air inlet 12 and flow to the first air outlet 13 from back to front along the through air duct 40, so that the ambient air which is not subjected to heat exchange is mixed with the heat exchange air flow which is subjected to heat exchange, the air output of the first air outlet 13 is improved, the air output temperature of the first air outlet 13 is eased, the air flow sent out by the first air outlet 13 is softer and is not too cold or too hot, and the comfort experience of a user is improved.

Specifically, the enclosure 10 may specifically include a front panel 101, a cover 102 located at a rear portion of the front panel 101, and a base 103 located at a bottom portion, where the front panel 101, the cover 102, and the base 103 cooperate to define a heat exchange air supply cavity. The first air supply fan 21, the second air supply fan 22 and the heat exchange device 30 are all arranged in the heat exchange air supply cavity. The air inlet 11 and the jet air inlet 12 can be formed on the housing 102, the air inlet 11 is located below the jet air inlet 12, the first air outlet 13 and the second air outlet 14 can be formed on the front panel 101, and the first air outlet 13 is higher than the second air outlet 14.

Further, a water receiving tray 31 may be disposed below the heat exchange device 30 to receive condensed water on the heat exchange device 30. The heat exchange device 30 is part of a refrigeration system that may be implemented using a compression refrigeration cycle that uses a refrigerant to transfer heat through a compression phase change cycle of a compressor, condenser, evaporator, and throttling device. The refrigerating system can also be provided with a four-way valve to change the flow direction of the refrigerant, so that the heat exchange device 30 alternately serves as an evaporator or a condenser to realize the refrigerating or heating function. Since the compression refrigeration cycle in an air conditioner is well known to those skilled in the art, the operation principle and construction thereof will not be described herein.

In some embodiments, the first air blower 21 is a centrifugal blower and the second air blower 22 is an axial flow blower.

The utility model selects the second air supply fan 22 for supplying air to the second air outlet 14 at the lower part as an axial flow fan, the air blown by the axial flow fan is spirally dispersed, and the air flow in the indoor lower space can be accelerated during heating, thereby heating is completed more quickly and more efficiently, and the problem of head heating and foot cooling is effectively avoided.

In some embodiments, the first air blower 21 and the second air blower 22 are spaced apart along the height direction of the cabinet 10, so as to fully utilize the advantage of the higher height of the cabinet air conditioner indoor unit 1 and reduce the lateral dimension and thickness dimension of the cabinet 10.

Further, the first air supply fan 21 is located below the first air outlet 13, and the second air supply fan 22 is located below the first air supply fan 21, so that the second air supply fan 22 with the axial flow fan supplies air towards the second air outlet 14 with the lower position, and the first air supply fan 21 with the centrifugal fan supplies air towards the first air outlet 13 with the higher position, thereby shortening the air supply path, reducing the wind resistance, and further improving the air supply amount.

In some embodiments, the air intake 11 is formed at the rear wall of the cabinet 10. The rotation axes of the first air supply fan 21 and the second air supply fan 22 extend along the front-rear direction of the casing 10, so that the first air supply fan 21 and the second air supply fan 22 both suck heat exchange air flow from the axial rear ends thereof, and the air flow direction is parallel to the axial directions of the first air supply fan 21 and the second air supply fan 22, thereby being beneficial to reducing wind resistance.

Further, the rotation axis of the first air supply fan 21 with the centrifugal fan extends back and forth, so that the air flow driven by the first air supply fan 21 is blown upward to the first air outlet 13. The rotation axis of the second air supply fan 22 with the axial flow fan extends back and forth, so that the air flow driven by the second air supply fan 22 is blown forward to the second air outlet 14.

Further, the heat exchanging arrangement 30 may be adjacently disposed at the front side of the air inlet 11 at the rear sides of the first and second air blowing fans 21 and 22.

In some embodiments, the cabinet air-conditioning indoor unit 1 further includes an air duct assembly 23, and the air duct assembly 23 defines a volute air chamber 231 and a through air chamber 232 therein that are spaced apart from each other.

Further, the first blower fan 21 is disposed in the volute air chamber 231, and the second blower fan 22 is disposed in the straight air chamber 232.

Since the volute air chamber 231 and the through air chamber 232 are spaced apart from each other, no air flow interference is formed between the two air chambers. Therefore, the air flow driven by the first air blower 21 and the air flow driven by the second air blower 22 do not interfere with each other.

The utility model forms two air cavities in one air duct component 23, which are respectively used for accommodating the first air supply fan 21 and the second air supply fan 22, thereby simplifying the air duct structure and the assembly process of the cabinet air conditioner indoor unit 1.

FIG. 5 is a schematic block diagram of a duct assembly according to one embodiment of the present utility model. In some embodiments, the volute plenum 231 has a first airflow inlet 2311 and a first airflow outlet 2312.

Specifically, the first air flow inlet 2311 is located at the rear side of the duct assembly 23 and faces rearward to allow air flow entering from the air intake 11 to enter the volute air chamber 231 through the first air flow inlet 2311. The first air flow outlet 2312 is located at the top end of the air duct assembly 23 and faces upward, and the first air flow outlet 2311 communicates with the through air duct 40 to allow the air flow in the volute air chamber 231 to flow to the through air duct 40 and thus to the first air outlet 13.

The positions of the first air inflow opening 2311 and the first air outflow opening 2312 of the volute air chamber 231 are selected to be matched with the air inflow and outflow characteristics of the centrifugal fan, the wind direction is changed least, and the wind resistance is smallest.

In some embodiments, the straight ventilation lumen 232 has a second airflow inlet 2321 and a second airflow outlet 2322 arranged in a straight pair.

Specifically, the second airflow inlet 2321 is located on a rear side of the duct assembly 23 and faces rearward to allow airflow entering from the air intake 11 to enter the plenum chamber 232 through the second airflow inlet 2321. The second airflow outlet 2322 is located at the front side of the air duct assembly 23 and faces forward, and the second airflow outlet 2322 is opposite to the second air outlet 14, so that the airflow in the through air cavity 232 flows to the second air outlet 14.

That is, the through-air chamber 232 is perforated in the front-rear direction so that the axial flow fan provided therein directly sucks air from the rear side and directly blows air to the front side.

The applicant has realized that the ambient air in the ambient space, which has not been subjected to heat exchange, flows into the through duct 40 by means of the promoting effect of the negative pressure, the amount of ambient air replenished at the first air outlet 13 is limited, and the promoting effect on the wind speed is not great.

For this, referring to a partial structural cross-sectional view of an indoor unit of a cabinet air conditioner according to another embodiment of the present utility model shown in fig. 6, the present utility model further provides at least one jet fan 50 in the through air duct 40. The jet fan 50 is configured to, when turned on, cause ambient air that has not been subjected to heat exchange to enter the through air duct 40 via the jet air inlet 12 and flow back and forth along the through air duct 40 to the first air outlet 13 to mix with the heat exchange air flow. On the one hand, the ambient air which is not subjected to heat exchange is mixed with the heat exchange air flow which is subjected to heat exchange, so that the air outlet temperature of the first air outlet 13 is alleviated, and the jet fan 50 has an obvious promotion effect on the ambient air and even the heat exchange air flow in the through air duct 40, so that the heat exchange air flow and more ambient air flow forward more quickly, the air outlet speed of the first air outlet 13 is effectively improved, the air supply distance of the first air outlet 13 is prolonged, and the defect of insufficient air supply distance of the existing cabinet air conditioner indoor unit 1 is overcome.

Specifically, the number of the jet fans 50 may be one or two. When the number of the jet fans 50 is two, one of them may be an induced draft fan and the other may be a blowing fan, so that the installation and support of the two jet fans 50 are facilitated.

In some embodiments, the cabinet air-conditioner indoor unit 1 further includes a jet air seat 60. The jet wind seat 60 is connected to the casing 10 inside the jet wind inlet 12. The interior of the jet air mount 60 is perforated in the fore-aft direction to define at least a partial section that forms the through air duct 40. That is, the through air duct 40 may be defined entirely by the jet air mount 60, or may be defined partially by the jet air mount 60. At least one jet fan 50 is disposed in a jet fan mount 60.

The cabinet air-conditioning indoor unit 1 of the present utility model is also provided with, in particular, a jet air seat 60, the jet air seat 60 being connected to the casing 10 inside the jet air inlet 12, at least a partial section of the through duct 40 being formed in the jet air seat 60. During assembly, the jet fan 50 can be assembled in the jet fan seat 60, and then the assembly formed by the jet fan 50 and the jet fan seat 60 is assembled to the casing 10, so that the convenience of assembling the jet fan 50 is improved. Meanwhile, the jet flow air seat 60 is utilized to form at least part of the through air duct 40, so that the design difficulty of directly arranging the through air duct 40 in the machine shell 10 is avoided, a reliable assembly foundation is provided for the jet flow fan 50, and the assembly stability of the jet flow fan 50 is improved.

In some embodiments, the cabinet air-conditioning indoor unit 1 further includes a ventilation bracket 71, and the ventilation bracket 71 is fixedly disposed inside the jet air seat 60 for supporting the jet fan 50. In assembly, the jet fan 50 may be mounted to the ventilation bracket 71 first, and then the assembly formed by the ventilation bracket 71 and the jet fan 50 may be assembled to the jet fan mount 60.

Further, the periphery of the ventilation bracket 71 is adjacent to the inner wall of the jet flow fan seat 60, that is, the ventilation bracket 71 is integrally erected in the jet flow fan seat 60, so that more structural connection points are arranged between the ventilation bracket 71 and the jet flow fan seat 60, the ventilation bracket 71 is conveniently and firmly erected in the jet flow fan seat 60, and the assembly stability of the jet flow fan 50 is further improved.

Still further, referring to the schematic exploded view of the ventilation bracket, the jet fan and the cover according to an embodiment of the present utility model shown in fig. 7, a first ventilation hole 711 is formed in the ventilation bracket 71. Since the ventilation bracket 71 occupies all the flow passing area of the through air duct 40 formed inside the jet air seat 60, the aperture area of the first ventilation hole 711 opened on the ventilation bracket 71 is preferably large in order not to affect the smooth forward flow of the air flow in the through air duct 40.

Preferably, the jet fan 50 is an axial flow fan disposed at the front side or the rear side of the ventilation bracket 71, and occupies a small space and has a strong driving force. The jet fan 50 may include a motor 52 fixed at the center of the ventilation bracket 71 and an axial flow fan 51 coaxially connected to the motor 52, the axial flow fan 51 being rotated about a horizontal rotation shaft extending forward and backward by the driving of the motor 52.

In some embodiments, the cabinet air-conditioning indoor unit 1 further includes a cover 72, and the cover 72 is disposed outside the jet fan 50 and connected to the ventilation bracket 71. The cover 72 is provided with a second ventilation hole 721 to allow the air flow driven by the jet fan 50 to flow into or out of the cover 72, thereby smoothly flowing in the through air duct 40.

The cover 72 and the ventilation bracket 71 together define a hollow closed space, and the jet fan 50 is positioned in the space, so that the user can be prevented from touching the jet fan 50 to cause safety accidents, and the appearance of the cabinet air conditioner indoor unit 1 is improved.

In some embodiments, the cover 72 includes a front or rear wall opposite the ventilation bracket 71, and a peripheral wall 722 extending rearward perpendicular to the front wall or forward perpendicular to the rear wall. The second ventilation hole 721 is formed in the front wall or the rear wall of the cover 72, and the peripheral wall 722 is formed with a third ventilation hole 723.

Specifically, the structure of the cover 72 varies depending on the relative positional relationship of the jet fan 50 and the ventilation bracket 71. For example, when the jet fan 50 is supported on the front side of the ventilation bracket 71, the cover 72 has a front wall, and the second ventilation hole 721 is opened on the front wall of the cover 72. As another example, when the jet fan 50 is supported on the rear side of the ventilation bracket 71, the cover 72 has a rear wall, and the second ventilation hole 721 is opened on the rear wall of the cover 72. The drawings of the present utility model illustrate an example in which the jet fan 50 is supported on the front side of the ventilation bracket 71.

The third ventilation holes 723 formed in the peripheral wall 722 of the cover 72 can enlarge the communication area between the jet fan 50 and the space outside the cover 72, so as to reduce adverse effects of the cover 72 on the driving effect of the jet fan 50 on the air flow as much as possible.

In some embodiments, the cabinet air-conditioner indoor unit 1 further includes an air guide assembly 80. The air guide assembly 80 is disposed in the through air duct 40, and the inside of the air guide assembly 80 is penetrated back and forth to define at least a partial section forming the through air duct 40.
