Currently, a double crossflow air conditioning unit has two fan systems for supplying air. Specifically, as shown in fig. 1, the double cross-flow air conditioner 2 is provided with an upper air outlet 21, a lower air outlet 22 and an air inlet 23; wherein, the upper air outlet 21 and the lower air outlet 22 are respectively positioned at the upper side and the lower side of the air inlet 23; the distances between the upper air outlet 21, the lower air outlet 22 and the air inlet 23 are shorter; after the double cross-flow air conditioning apparatus is installed, the upper outlet 21 is located at a position close to the ceiling 1. When the dual-through-flow air conditioning equipment is used for refrigerating, because the air flow pressure difference between the air inlet 23 and the upper air outlet 21 and the air flow pressure difference between the air inlet 23 and the lower air outlet 22 are large, the air flows of the upper air outlet 21 and the lower air outlet 22 are easily sucked into the air inlet 23, and therefore condensed water and backflow loss of the air flows are formed in the air outlet area of the dual-through-flow air conditioning equipment. When the double-cross-flow air conditioning equipment heats, the hot air flow is easy to float upwards due to expansion and contraction of the air flow and the fact that the upper air outlet 21 is close to the ceiling 1, and therefore large energy loss is generated.
In the prior art, a baffle is arranged at an outlet area of a certain cross-flow fan blade to prevent airflow at an air outlet from being sucked into an air inlet, and hot airflow at the air outlet is prevented from floating upwards by independently controlling the movement of one of the cross-flow fan blades, so that energy loss is reduced.
However, the inventors of the present invention found that: no matter whether the air outlet area is provided with the baffle or not, when the cross-flow fan blade of one fan system is controlled to operate, due to the influence of pressure difference in the air passages of the two fan systems, the other cross-flow fan blade can automatically operate under the driving of air flow, and therefore the air flow rotates in an indoor cavity of the air conditioning equipment to generate abnormal noise.

Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Example 1
The embodiment provides an air supply device, which is used on air conditioning equipment and used for conveying airflow subjected to heat exchange in an inner cavity of the air conditioning equipment through a heat exchanger to the indoor space. Specifically, as shown in fig. 2, the air supply device includes at least two air duct assemblies. Each air duct assembly includes an air duct 41, a fan and a guidance device 43. Wherein, one end of the air duct 41 is set as an air inlet for the air flow after heat exchange by the heat exchanger to enter the air duct 41. The other end of the air duct 41 is provided as an air outlet 44 for delivering the airflow entering the air duct 41 to the room. The fan is disposed in the air duct at a position close to the air inlet of the air duct 41, so that the air flow after heat exchange enters the air duct 41 under the cooperation of the guiding and controlling device, and the air flow in the air duct 41 is delivered to the room through the air outlet 44. The guiding and controlling device 43 is arranged at the air inlet of the air duct 41. When the air duct assembly works, the guiding and controlling device 43 guides the air flow after heat exchange by the heat exchanger, so that the air flow is guided into the air duct 41 from the air inlet of the air duct. When the air duct assembly stops working, the guiding and controlling device closes the air inlet of the air duct 41 to isolate the air flow in the inner cavity of the air conditioning equipment from the fan in the air duct 41.
The air supply device provided by the embodiment has the advantages that the air inlet of the air channel in each air channel component is provided with the guide control device, so that the air channel components are independent from each other, and no mutual influence exists. When one or more air duct assemblies are in a working state, the fan blades in the air duct assemblies in a stop working state are isolated from the air flow in the indoor cavity of the air conditioning equipment under the action of the guide control device and cannot rotate under the driving of the air flow, so that the situation that abnormal noise occurs in the air duct of the air conditioning equipment in the prior art is avoided.
In addition, as shown in fig. 2, the air duct assembly in this embodiment further includes a housing, and the air duct is disposed in the housing, and preferably, the housings of any two adjacent air duct assemblies are connected by a connecting plate.
Preferably, the air supply direction of each air duct assembly in the embodiment is different, so as to enlarge the air supply angle of the air supply device, thereby enhancing the comfort level of the air conditioning equipment.
Example 2
Preferably, as shown in fig. 2, the present embodiment provides an air supply device, and compared with the previous embodiment, the guiding and controlling device 43 in the present embodiment includes a plurality of guiding vanes 430 arranged at the air inlet of the air duct 41. When the air duct assembly stops working, the guide control device 43 includes a plurality of guide vanes 430 to form a closed door for closing the air inlet of the air duct 41, so as to isolate the air flow from the fan in the air duct 41. Preferably, the closing door is of a circular arc structure.
When the air duct assembly is in an operating state, the flow deflectors 430 of the guiding and controlling device 43 are disposed at intervals (that is, a gap for allowing an air flow to pass through exists between any two adjacent flow deflectors 430), and each flow deflector 430 guides the air flow subjected to heat exchange by the heat exchanger, so that the air flow enters the air duct 41. Wherein the dotted lines in fig. 2 indicate the corresponding positions when the guide vanes 430 are closed.
Preferably, the plurality of flow deflectors 430 of the guiding and controlling device in this embodiment are arranged in different installation directions according to the blade angle of the fan blade in the fan, so as to guide the airflow.

The guide control device in the embodiment comprises the guide vanes arranged at the air inlet of the air duct, so that on one hand, when the air duct assembly works, the guide vanes in the spaced state can guide the airflow in the inner cavity of the air conditioning equipment, thereby improving the flow direction of the airflow at the inlet of the blade when the fan blade runs, reducing the obstruction and separation of the airflow, and reducing the airflow separation loss of the running fan in the air inlet area. On the other hand, when the air duct assembly stops working, the guide vanes form a closed door for closing the air inlet of the air duct, so that the air flow and the fan blades can be completely separated, and abnormal noise caused by disturbance of the air flow on the fan blades is avoided.
Example 3
Preferably, the present embodiment provides an air supply device, and as shown in fig. 2, the blower includes a first motor and a fan blade 42, and the fan blade 42 in the present embodiment is preferably a cross-flow fan blade. And the guide control device 43 further comprises a second motor for driving the guide vane 430 to rotate.
Preferably, the first motor and the second motor are the same motor. The operating states of the fan and the pilot control device 43 can be synchronized well by such an arrangement. That is, the guiding and controlling device 43 will close the air duct of the air duct assembly as long as the blower of the air duct assembly stops running.
Preferably, the guiding and controlling device in this embodiment further includes a connecting rod (not shown in the figure), and the plurality of guiding vanes are all disposed on the connecting rod and can rotate relative to the connecting rod. When the air duct assembly stops working, the guide vanes on the connecting rod are located at the first position, namely the guide vanes are mutually connected to form a closed door for closing the air inlet of the air duct. When the air duct assembly is in an operating state, the guide vanes are in a second position, i.e., the guide vanes are spaced apart from each other, to direct the airflow into the air duct from the gap between the guide vanes.
Example 4
Preferably, the present embodiment provides an air supply device, and compared with the above embodiments, the number of the air duct assemblies in the present embodiment is two, and the two air duct assemblies are respectively the first air duct assembly and the second air duct assembly. As shown in fig. 3, the first air duct assembly includes an air duct 411, a blower and a guiding and controlling device 431; the fan includes through-flow fan 421, and the one end of wind channel 411 is provided with the air intake, and the other end is provided with air outlet 441.

In this embodiment, the air supply direction of the first air duct assembly is different from the air supply direction of the second air duct assembly, so that the air supply angle of the air supply device is increased, and the comfort of the air conditioning equipment is improved.
The housing 451 of the first air duct assembly in this embodiment is connected to the housing 452 of the second air duct assembly by a connecting plate 46.

Example 5
On the other hand, as shown in fig. 3, 4, 5 and 6, the present embodiment provides an air conditioner, which includes a housing 31, a heat exchanger 33 and the blower device according to any of the above embodiments. Wherein, the housing 31 is provided with an air outlet and an air inlet 32. The heat exchanger 33 is disposed in the casing 31 at a position facing the air intake opening 32. The air blowing device is provided in the casing 31. The number of the air outlets of the air supply device is consistent with that of the air outlets on the shell 31, and the air outlets are correspondingly communicated. Indoor air flow enters the air conditioning equipment from an air inlet 32 on the air conditioning equipment shell 31, and is conveyed to the indoor space by an air supply device after heat exchange through a heat exchanger 33.
The air conditioning equipment in the embodiment has the beneficial effects of any embodiment through the air supply device comprising any embodiment, namely, the air duct assemblies of the air conditioning equipment are independent from each other, no mutual influence exists, and the occurrence of abnormal noise in the air duct in the prior art can be avoided; and the air flow separation loss of the running fan in the air inlet area is reduced.
Example 6
As shown in fig. 3 to 6, preferably, the present embodiment provides an air conditioning apparatus, and compared with embodiment 5, the air duct assembly in the present embodiment includes a first air duct assembly and a second air duct assembly. Correspondingly, the number of the air outlets on the air conditioning equipment shell is two, namely the first air outlet and the second air outlet. The air outlet 441 of the first air duct assembly is communicated with the first air outlet; the air outlet 442 of the second air duct assembly is communicated with the second air outlet. The first air outlet is arranged above the air inlet 32 on the air conditioner casing, and the second air outlet is arranged below the air inlet 32 on the air conditioner casing.
In addition, the first air outlet of the air conditioning apparatus shown in fig. 3 to 6 coincides with the air outlet 441 of the first air duct assembly, and the second air outlet of the air conditioning apparatus coincides with the air outlet 441 of the second air duct assembly.
In practical installation of the air conditioning equipment provided by the embodiment, the first air outlet is an upper air outlet of the air conditioning equipment and is positioned close to a ceiling; the second air outlet is a lower air outlet of the air conditioning equipment. The inlet 32 of the air conditioning apparatus is located between the first outlet and the second outlet.
Example 7
On the other hand, this embodiment provides an air supply method for an air conditioning apparatus, which mainly uses the air conditioning apparatus of embodiment 5 or embodiment 6 to deliver the airflow, which has been subjected to heat exchange by the heat exchanger 33, in the cavity of the air conditioning apparatus to the room.
Preferably, when the air conditioning equipment stops working, the air duct assemblies on the air conditioning equipment stop working. As shown in fig. 3, both the first air duct assembly and the second air duct assembly stop working. Specifically, the cross-flow fan 421 of the first air duct assembly stops operating, and the guide and control device 431 seals the air inlet of the air duct 411, so that the inner flow of the inner cavity of the air conditioning equipment cannot pass through the air duct 411. The cross-flow fan 422 of the second air duct assembly stops operating, and the guiding and controlling device 432 closes the air inlet of the air duct 412, so that the air flow in the inner cavity of the air conditioning equipment cannot enter the air duct 412.
Preferably, when the air conditioner is in the windshield mode, all air duct assemblies on the air conditioner are in working states. As shown in fig. 4, the first air duct assembly and the second air duct assembly are simultaneously in operation. Specifically, the cross-flow fan 421 of the first air duct assembly operates, and the guide vanes of the guide control device 431 are opened, so that part of the air flow after heat exchange by the heat exchanger 33 in the air conditioning equipment is guided into the air duct 411, and then is conveyed to the indoor space through the air outlet 441 by the operation of the fan. The cross-flow fan 422 of the second air duct assembly operates, and the guide vanes of the guide control device 432 are opened at the same time, so that another part of the air flow after heat exchange in the air conditioning equipment by the heat exchanger 33 is guided into the air duct 412, and then is conveyed to the indoor space from the air outlet 442 by the operation of the fan.
Preferably, when the air supply device of the air conditioning equipment comprises a first air duct assembly and a second air duct assembly, and the air conditioning equipment is used for refrigerating, the first air duct assembly is in a working state, and the second air duct assembly stops working. Specifically, as shown in fig. 5, the cross-flow fan 421 of the first air duct assembly operates, and the guide vanes of the guide control device 431 are opened, so that the air flow after heat exchange by the heat exchanger 33 is completely guided into the air duct 411, and then is conveyed to the indoor space through the air outlet 441 by the operation of the fan. The cross-flow fan 422 of the second air duct assembly stops running, and the guide and control device 432 closes the air inlet of the air duct. Here, due to the sealing effect of the air duct in the second air duct assembly of the guidance and control device 432, the air flow in the air conditioning equipment cannot enter the second air duct assembly, and the second air duct assembly keeps a static state due to the fact that no air flow does work and no air flow disturbing force exists, so that abnormal noise in the air duct of the second air duct assembly is eliminated. In addition, because the air conditioning equipment only has one air duct component to work under the refrigeration mode, the phenomenon that the airflow at the air outlet is sucked into the air inlet reversely can not occur under the refrigeration mode of the air conditioning equipment.
Here, the air conditioning equipment can also be realized by the following modes during cooling: even if the first air duct assembly stops working, the second air duct assembly is in a working state (this mode can be seen in the structural schematic diagram of the air conditioning apparatus shown in fig. 6). Specifically, as shown in fig. 6, the cross-flow fan 422 of the second air duct assembly operates, and the guide vanes of the guide control device 432 are opened at the same time, so that the air flow after heat exchange by the heat exchanger 33 in the air conditioning equipment is completely guided into the air duct, and then is conveyed to the indoor space through the air outlet 442 by the operation of the fan. The cross-flow fan 421 of the first air duct assembly stops operating, and the guiding and controlling device 431 seals the air inlet of the air duct in the first air duct assembly. The mode can also eliminate abnormal noise in the air duct of the air conditioning equipment, and the phenomenon that air flow at the air outlet is sucked into the air inlet reversely can not occur.
Preferably, when the air supply device of the air conditioning equipment comprises the first air duct assembly and the second air duct assembly and the air conditioning equipment heats, the second air duct assembly is in a working state, and the first air duct assembly stops working. Specifically, as shown in fig. 6, the cross-flow fan 422 of the second air duct assembly operates, and the guide vanes of the guide control device 432 are opened, so that the air flow after heat exchange by the heat exchanger 33 in the air conditioning equipment is completely guided into the air duct 412, and then is conveyed to the indoor space through the air outlet 442 by the operation of the fan. The cross-flow fan 421 of the first air duct assembly stops operating, and the guiding and controlling device 431 seals the air inlet of the air duct in the first air duct assembly. Because the air inlet of the air duct in the first air duct assembly is in a closed state, air flow in the air conditioning equipment cannot enter the air duct in the first air duct assembly, and therefore abnormal noise in the air duct of the second air duct assembly is eliminated. In addition, since the hot air flow in the air conditioning equipment is completely conveyed to the indoor space through the air outlet 442 of the second air duct assembly (i.e., is output from the lower air outlet of the air conditioning equipment) to achieve the heating effect, no hot air flow is blown out of the upper air outlet of the air conditioning equipment, so that the hot air flow can be prevented from floating upwards, and the energy loss is avoided.
The person skilled in the art will readily understand that the advantageous ways described above can be freely combined, superimposed without conflict.
To sum up, the air supply device, the air conditioning equipment and the air supply method of the air conditioning equipment provided by the embodiment of the invention realize the effect of guiding the air flow when in work and the purpose of completely separating the air flow from the fan blades in the air duct when in stop work by designing the guide control device comprising the guide vanes arranged at the air inlet of the air duct, thereby avoiding the occurrence of abnormal noise of the air duct caused by disturbance of the air flow to the fan blades in the stop work state.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are still within the scope of the technical solution of the present invention.
