An air conditioner 1 according to an embodiment of the present invention is described below with reference to the drawings. The air conditioner 1 may be used to regulate the indoor ambient temperature. Specifically, the air conditioner 1 may be an integrated air conditioner 1, for example, the air conditioner 1 is a mobile air conditioner or a window type air conditioner.
As shown in fig. 1, 4 and 5, an air conditioner 1 according to an embodiment of the present invention may include a case 10, a first heat exchanger 30, a second heat exchanger 40, a wind wheel 20, and a switch 50.
As shown in fig. 4, the casing 10 has an air duct a, and as shown in fig. 2 to fig. 3, an air inlet d is provided on the casing 10, the air inlet d is communicated with the air duct a, a first air outlet e is provided on the casing 10, the first air outlet e is communicated with the air duct a, a second air outlet f is provided on the casing 10, the second air outlet f is communicated with the air duct a, that is, the casing 10 is provided with an air inlet d, a first air outlet e and a second air outlet f, and the first air outlet e, the air inlet d and the second air outlet f are all communicated with the air duct a. Thereby, circulation of the airflow between the casing 10 and the indoor environment in which the air conditioner 1 is located can be facilitated.
Specifically, the first heat exchanger 30 and the second heat exchanger 40 are both located within the air duct a. That is, the first heat exchanger 30 is installed in the air path a, and the second heat exchanger 40 is installed in the air path a, so that the air flow in the air path a exchanges heat with the first heat exchanger 30 and the second heat exchanger 40.
One of the first heat exchanger 30 and the second heat exchanger 40 is an evaporator, and the other of the first heat exchanger 30 and the second heat exchanger 40 is a condenser, that is, the first heat exchanger 30 may be an evaporator, the second heat exchanger 40 may be a condenser, the first heat exchanger 30 may be a condenser, and the second heat exchanger 40 may be an evaporator.
Specifically, the air conditioner 1 may be a single cooling type air conditioner 1, or may be a cooling and heating type air conditioner 1; when the air conditioner 1 is a single-cooling type air conditioner 1, the first heat exchanger 30 is an evaporator, and the second heat exchanger 40 is a condenser; when the air conditioner 1 is a cooling and heating type air conditioner 1, the first heat exchanger 30 is an evaporator, the second heat exchanger 40 is a condenser, and in the heating mode, the first heat exchanger 30 is a condenser, and the second heat exchanger 40 is an evaporator. Therefore, on one hand, the evaporator and the condenser are integrated in the shell 10, so that the air conditioner 1 is an integrated air conditioner 1, and compared with the split air conditioner 1, when the air conditioner is used at a client, an inner unit and an outer unit do not need to be installed on a door, so that the labor cost is saved, and the cost is reduced; on the other hand, the evaporator and the condenser are both positioned in the same air duct a, the structure is simpler and more compact, independent air ducts corresponding to the evaporator and the condenser respectively do not need to be arranged, the production efficiency is favorably improved, and the cost is more favorably reduced.
The wind wheel 20 is located in the air duct a, that is, the wind wheel 20, the first heat exchanger 30 and the second heat exchanger 40 are all located in the same air duct a, and the air duct a is shared by the three. From this, through all setting up evaporimeter, condenser and wind wheel 20 in wind channel a, evaporimeter and condenser sharing wind channel a and wind wheel 20 promptly, the structure is simpler and compact, is favorable to improving production efficiency, and reduce cost can simplify the structure of air conditioner 1.
The switch 50 is movably provided on the housing 10 to open or close the first outlet e. For example, when the air conditioner 1 is a single cooling type air conditioner 1, the switch 50 opens the first outlet e when the air conditioner 1 is in the cooling mode, and the switch 50 closes the first outlet e when the air conditioner 1 is in the dehumidifying mode. For another example, when the air conditioner 1 is a cooling and heating type air conditioner 1, the switch 50 opens the first air outlet e when the air conditioner 1 is in the cooling mode and the heating mode, and the switch 50 closes the first air outlet e when the air conditioner 1 is in the dehumidifying mode. For convenience of description, the following description will be given taking as an example that the air conditioner 1 opens the first outlet e in the cooling mode by the switching member 50.
In the cooling mode, referring to fig. 6, the switch 50 opens the first air outlet e, when the wind wheel 20 works, the wind wheel 20 can drive an air flow to enter the air duct a from the air inlet d, a part of the air flow entering the air duct a exchanges heat with the first heat exchanger 30 to form a first heat exchange air flow and is discharged from the first air outlet e, and the rest of the air flow entering the air duct a exchanges heat with the second heat exchanger 40 to form a second heat exchange air flow and is discharged from the second air outlet f, so that in the cooling mode, the first heat exchanger 30 corresponds to the first air outlet e, the air flow exchanging heat with the first heat exchanger 30 flows out from the first air outlet e, the second heat exchanger 40 corresponds to the second air outlet f, and the air flow exchanging heat with the second heat exchanger 30 is discharged from the second air outlet f.
In a dehumidification mode, referring to fig. 7, the switch 50 closes the first air outlet e, the wind wheel 20 drives the air flow to enter the air duct a from the air inlet d, a part of the air flow entering the air duct a firstly flows to the first heat exchanger 30, exchanges heat with the first heat exchanger 30, flows to the second heat exchanger 40 and is discharged from the second air outlet f, and the rest of the air flow entering the air duct a flows to the second heat exchanger 40, exchanges heat with the second heat exchanger 40 and is discharged from the second air outlet f, so that in the dehumidification mode, the first heat exchanger 30 and the second heat exchanger 40 correspond to the second air outlet d, and all the air flow entering the air duct a from the air inlet d is discharged from the second air outlet f.
Specifically, in the dehumidification mode, because the first heat exchanger 30 is an evaporator, a part of the air flow entering the air duct a flows through the first heat exchanger 30 and is cooled and dehumidified for the first time to generate condensed water, and then the condensed water forms a cold air flow, the cold air flow further flows to the second heat exchanger 40, and the rest of the air flow entering the air duct a flows to the second heat exchanger 40 and is heated to form a hot air flow.
It can be understood that, when the air conditioner 1 is a cooling and heating type air conditioner 1, in the heating mode, the switch 50 opens the first air outlet e, when the wind wheel 20 works, the wind wheel 20 can drive the air flow to enter the air duct a from the air inlet d, a part of the air flow entering the air duct a forms a first heat exchange air flow after exchanging heat with the first heat exchanger 30 and is discharged from the first air outlet e, and the rest of the air flow entering the air duct a forms a second heat exchange air flow after exchanging heat with the second heat exchanger 40 and is discharged from the second air outlet f.
According to the air conditioner 1 provided by the embodiment of the invention, the first heat exchanger 30, the second heat exchanger 40 and the wind wheel 20 are arranged in the same air duct a, and the switch member 50 is further arranged on the basis, so that the first air outlet e is opened or closed by using the switch member 50, the structure is simpler and more compact, the production efficiency is improved, the cost is reduced, and the structure of the air conditioner 1 is simplified, the flow passages can be rapidly switched by opening and closing the switch member 50, the dehumidification purpose is realized by using a cold and hot air mixing mode, the dehumidification effect is good, the air conditioner 1 can independently realize the refrigeration function, the dehumidification function can also be independently realized, namely, the temperature reduction and dehumidification are not required, and the use requirements of users are further met.
In some embodiments of the present invention, as shown in fig. 4, the first heat exchanger 30 and the second heat exchanger 40 are disposed opposite to each other in a first direction, the first air outlet e is located on a side of the first heat exchanger 30 away from the second heat exchanger 40, the second air outlet f is located on a side of the second heat exchanger 40 away from the first heat exchanger 30, the wind wheel 20 is located between the first heat exchanger 30 and the second heat exchanger 40, the wind wheel 20 is opposite to the air inlet d in a second direction, and the second direction is perpendicular to the first direction. Therefore, the structure is simple and compact.
For example, the first heat exchanger 30 and the second heat exchanger 40 may be arranged oppositely in the horizontal direction, as shown in fig. 2 and 4, the first heat exchanger 30 and the second heat exchanger 40 are both arranged vertically, the first heat exchanger 30 is located at the front side of the second heat exchanger 40, the front side wall of the housing 10 is provided with a first air outlet e, the rear side wall of the housing 10 is provided with a second air outlet f, the top wall or the bottom wall of the housing 10 is provided with an air inlet d, and the air inlet d is opposite to the wind wheel 20 in the up-down direction.

Thus, by arranging the wind wheel 20 as the centrifugal wind wheel 20, it is convenient to realize that the centrifugal wind wheel 20 drives the air flow to the first heat exchanger 30 and the second heat exchanger 40 respectively in the cooling mode and the dehumidifying mode.
In some embodiments of the present invention, referring to fig. 5, the switch element 50 is a wind deflector, and the wind deflector is rotatably disposed at the first wind outlet e. Therefore, the switch piece 50 is constructed into the air deflector, so that the function of opening and closing the first air outlet e can be achieved, the function of air guiding can also be achieved, and the use requirements of users can be met.
Of course, the present invention is not limited to this, and in other embodiments, the opening and closing member 50 may also be an opening and closing door movably disposed on the casing 10 for opening or closing the first air outlet e, which is simpler.
In some embodiments, the switch member 50 is a one-piece molded member. For example, the switch member 50 is an integrally injection-molded member. From this, the structure of an organic whole piece not only can guarantee switch 50's structure, stability of performance to convenient shaping, manufacturing are simple, have saved unnecessary assembly part and connection process moreover, have improved switch 50's assembly efficiency greatly, guarantee the reliability that switch 50 connects, and moreover, the bulk strength and the stability of the structure of an organic whole formation are higher, and it is more convenient to assemble, and the life-span is longer.
