Description

BACKGROUND(a) Technical FieldThe present disclosure relates to a roof air conditioner. More particularly, the present disclosure relates to a roof air conditioner mounted in a vehicle roof and configured to selectively exhaust conditioned air.(b) Background of the Prior ArtAn air conditioner provided as part of a vehicle is configured to cool or heat the vehicle interior in summer or winter and / or remove frost from the windshield in rain weather or winter, thereby securing the front-rear view of the driver. The air conditioner is usually equipped with a heating system and a cooling system, and selectively introduces, i.e., draws in, outside air or inside air. Subsequently, this introduced air is heated or cooled and blown into the vehicle interior, whereby the vehicle interior is cooled, heated or ventilated.A general vehicle air conditioner is typically a front air conditioner, and the air to be cooled or heated is configured to be discharged from an outlet port formed in a dashboard at the front end of the vehicle compartment. In vehicles having a large interior, such as luxury cars or SUVs, the present air conditioner may not provide enough air to cool or warm the rear seats.In order to solve the above-described problem, in the case of a vehicle having a large interior, an air conditioner for the rear seat or a roof air conditioner installed on the vehicle roof may be used. The roof air conditioner is configured to discharge conditioned air via the heads of the occupants of the vehicle, and is separately installed, thereby assisting the cooling and heating performance for the rear seats.In a conventional construction related to a roof air conditioner for a vehicle, the roof air conditioner includes a plurality of air passages provided in a part of a space in a housing installed on a vehicle roof. Each of the air passages may include a condenser, an evaporator, and a fan. The roof air conditioner also includes a refrigerant cycle system accommodated in a separate space in the housing and configured to circulate the refrigerant using the condenser and the evaporator.Another air duct is configured to cool air introduced from the inside of the vehicle through the evaporator by means of forced air blown from a cross flow fan, and perform a cooling function and an air conditioning function by discharging the air through the vehicle roof or from the vehicle roof.When the air conditioner is mounted on the vehicle roof, the roof is enlarged. This can affect not only the internal and external appearance of a vehicle, but also the driving performance of a vehicle.The roof air conditioner of the prior art is equipped with a cross flow blower applied thereto. The length of the roof air conditioning system therefore increases upwards and downwards, which makes it more difficult to install the roof air conditioning system in the vehicle roof. Here, the height of a vehicle increases even if the air conditioner is installed outside the roof. Accordingly, the roof air conditioner can be installed in large buses, but it may be difficult to install the roof air conditioner in passenger cars and delivery cars.In addition, since the roof air conditioner is configured to discharge only cooled and heated air into the vehicle interior, it is difficult to provide an additional discharge port that serves to perform dehumidification of the front and rear windows of the vehicle.The statements disclosed in the above-referenced background section are merely intended to make the background of the disclosure more comprehensible. Thus, the background section may contain statements that do not form prior art, as already known to one of ordinary skill in the art.SUMMARY OF THE INVENTIONThe present disclosure is directed to solving the above-described problems related to the related art. It is the object of the present disclosure to provide a roof air conditioner configured to selectively discharge air introduced into a housing including a first flow path and a second flow path through a first discharge port and a second discharge port.Further, it is an object of the present disclosure to provide a roof air conditioner configured to provide a shutter disposed in the first flow path and control the air to be discharged depending on a predetermined temperature through a cooling flow path and a bypass flow path.The objects of the present disclosure are not limited to the above-mentioned objects.

In the description of the embodiments with reference to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals throughout the specification and the drawings, and overlapping descriptions have been omitted.FIG. 1 is a diagram of the roof air conditioners 1 located at or near the front end of the passenger compartment of a vehicle and the rear end thereof according to an embodiment of the present disclosure. FIG. 2 is a diagram illustrating the configurations of a first outlet port 110 and a second outlet port 210 of the roof air conditioner 1. Moreover, FIG. 3 illustrates a position illustration of the components of the roof air conditioner 1.The roof air conditioner 1 of the present disclosure is inserted into the roof of a vehicle when it is disposed adjacent to the front windshield or the rear windshield, i.e., the windshield of the vehicle. The roof air conditioner 1 is configured to include a plurality of flow paths formed in a housing 2. At least one flow path may also be configured to include a plurality of bypass flow paths.The first outlet opening 110 is in flow communication with a first flow path 100 and is arranged at one end of the roof air conditioning system 1. The second outlet port 210 is fluidly connected to a second flow path 200 and is disposed at the other end of the roof air conditioner 1. In this example, the roof air conditioner 1 has two such first outlet ports 110 and two such second outlet ports 210, and the roof air conditioner may have more or less than these two outlet ports. Moreover, the cooled or heated air in the housing 2 is configured to be discharged into the passenger compartment of a vehicle via the first discharge opening 110 and directed toward the passengers or seats. The cooled or heated air in the housing 2 is also configured to be discharged through the second discharge port 210 at the inside of the glass. The first outlet port 110 is provided with flaps, i.e., vanes (not illustrated). One of the wings (left wing) is disposed on the left side of a partition wall, a partition wall, a louver, or the like, i.e., a bezel 150 disposed in the housing 2, and the other of the wings (right wing) is disposed on the right side of the bezel 150. In one example, the left and right blades are independently controllable, and the temperature of the discharged air and the directivity on the left side of the one discharge port, and the temperature of the discharged air and the directivity on the right side may be independently set.In addition, the roof air conditioner 1 includes a blower 10 disposed at one end of the housing 2, and the housing 2 and the blower 10 are configured to introduce air from the vehicle interior or air supplied from the outside into the interior. The blower 10 is arranged in the vertical direction of the housing 2 in this example and is configured in the form of a fan. According to an embodiment of the present disclosure, the blower 10 may further include a fan, e.g., a Sirocco fan, arranged to suck air into the housing 2 from the outside of the housing 2 in the vertical direction. The sucked air is configured to be discharged through the first flow path 100 and / or the second flow path 200 in the housing 2.An evaporator 20 is arranged in the housing 2 in at least a part of the first flow path 100. When the air supplied from the blower 10 flows through or along the first flow path 100, at least a part of the air is configured to flow through the evaporator 20. Furthermore, the roof air conditioner 1 includes the shutter 150 disposed in the first flow path 100, which is configured to divide a cooling flow path 120 of the first flow path 100 into two sub flow paths 101 and 102. The orifice 150 is formed so as to be integrated with the housing 2 and is in a state of flowing through the evaporator 20. Accordingly, the air introduced into each of the sub flow paths 101, 102 is configured to flow through at least a part of the evaporator 20.In other words, the first flow path 100 includes the cooling flow path 120 configured to cause air to be discharged therethrough via the evaporator 20, and includes a bypass flow path 130 configured to cause air to be discharged therethrough while bypassing the evaporator 20. Moreover, the cooling flow path 120 includes the first sub flow path 101 and the second sub flow path 102 each obtained by dividing the cooling flow path 120 into two sub flow paths using the orifice 150. Specifically, the shutter 150 divides the cooling flow path 120 into left and right sides.In this way, the first flow path 100 of the present disclosure includes the cooling flow path 120 flowing through the evaporator 20 and the bypass flow path 130 bypassing the evaporator 20. The cooling flow path 120 includes the first flow path 101 and the second sub flow path 102 each obtained by dividing the cooling flow path 120 into the two sub flow paths by using the orifice 150.A temperature door 140 is rotatably disposed in the housing 2 between the first flow path 100 and the blower 10. Moreover, the temperature door 140 is configured to simultaneously control the opening and closing of the cooling flow path 120 and the bypass flow path 130. The temperature flap 140 is arranged and configured such that the opening and closing of the cooling flow path 120 and the opening and closing of the bypass flow path 130 may deviate from each other. In other words, the temperature flap 140 may be configured to control an opening amount of the cooling flow path 120 and an opening amount of the bypass flow path 130, respectively.In an embodiment of the present disclosure, the temperature door or doors 140 on the left side of the bezel 150 and the temperature door or doors 140 on the right side may be controlled independently of each other. Each of the temperature doors 140 includes a door configured to be disposed at different angles relative to a central shaft penetrating the housing 2. In addition, a flap corresponding to each sub flow path 101 or 102 and a flap corresponding to the corresponding bypass flow path 130 adjacent to the sub flow path are configured to form an angle of 90 degrees therebetween. When the sub flow path 101 or 102 is opened, the corresponding bypass flow path 130 may be closed, and when the bypass flow path 130 is opened, the respective sub flow path 101 or 102 may be placed in a closed state. Furthermore, the central shaft supporting the flaps may be rotated to open both the bypass flow path 101 or 102 and the corresponding bypass flow path 130. Thereby, an opening amount for the temperature door 140 can be adjusted.In an embodiment of the present disclosure, the temperature door 140 may include a first temperature door 141 and a second temperature door 142 with the shutter 150 being centrally disposed therebetween. In other words, a temperature flap 141 or 142 may integrally control the opening and closing of the respective sub flow path 101 or 102 and the bypass flow path 130 adjacent to the sub flow path. In an embodiment of the present disclosure, a temperature door 140 is disposed on each of the left side (temperature door 141) of the bezel 150 and the right side (temperature door 142) thereof.In this way, the bypass flow path 130 adjacent to the first sub flow path 101 is maintained in a fully closed state via the first temperature flap 141 when the first sub flow path 101 is fully opened. In addition, the bypass flow path 130 adjacent to the second sub flow path 102 is switched to a fully closed state via the second temperature flap 142 when the second sub flow path 102 is fully opened.A switching door 400 is disposed at a branching location of the first flow path 100 and the second flow path 200, and a switching door 400 is disposed adjacent to the first outlet port 110 to control the opening and closing of the second flow path 200 and the opening and closing of the first outlet port 110. The switching doors 400 may be controlled to open the first outlet opening 110 and close the second flow path 200 when the passenger compartment of the vehicle needs to be cooled or heated. In addition, the switching doors 400 may be controlled when dehumidifying the glass to open the second flow path 200 and close the second discharge port 110.The switching door 400 disposed between the first flow path 100 and the second flow path 200 and the switching door 400 disposed at the inner end of the first outlet port 110 may be integrally controlled, respectively. In addition, the switching door 400 disposed at the inner end of the first outlet opening 110 may be divided into a left switching door 400 and a right switching door 400 with the shutter 150 being centrally disposed therebetween. The left switching door 400 and the right switching door 400 may be independently controlled in response to the temperature settings in the occupant compartment of the vehicle. The switching flap 400 arranged between the first flow path 100 and the second flow path 200 can further comprise a switching flap 400 on each side of the housing 2, since in the illustrated embodiment a first and a second flow path 100, 200 are present on each side of the roof air conditioning system 1.The roof air conditioner 1 includes the second flow paths 200 that are formed to branch from the first flow path or the first flow paths 100 and are respectively located on the opposite sides of the first flow path or the first flow paths 100, and that are configured to perform defrosting. The switching doors 400 respectively disposed on the opposite sides of the housing 2, which are respectively disposed at the locations where the first flow path 100 and the second flow path 200 diverge, are integrally opened and closed. Each of the switching doors 400 provided at the location where the first flow path 100 and the second flow path 200 diverge may be formed of a door rotated about a central shaft in the height direction of the housing 2. Accordingly, in response to the input of a defrost mode by a user, the second flow paths 200 may be switched to an open state by rotating the switching doors 400 about the central shaft. With this arrangement, the air introduced from the blower 10 can be discharged to the second discharge port 210 via the second flow path 200 and caused to flow along one side, i.e., along the vehicle inner side of the windshield.Moreover, the switching flap 400 arranged at the first outlet opening 110 and divided by the panel 150 is divided into the left switching flap 400 and the right switching flap 400. The left switching door 400 and the right switching door 400 may be opened and closed independently in response to a user's request.In this way, the switching doors 400 are respectively located at a front end of the second flow path or the second flow paths 200 and an inner portion of the first outlet port 110, and each of the switching doors 400 can be controlled to be opened and closed independently.FIG. 4 is a diagram illustrating, as an embodiment of the present disclosure, a relationship between configurations in which air in the housing 2 is discharged through the second outlet port or the second outlet ports 210 when a defrosting mode is input, i.e., selected by a user.The air flowing through the blower 10 is moved in the housing 2 through the first flow path 100. In addition, the switching door 400 disposed at a branch of the first flow path 100 configured to open and close the second flow path 200 is switched to the open state. Here, the switching door 400 formed in the first outlet opening 110 may be opened or closed in response to a request from a user.The air introduced into the first flow path 100 is moved through the cooling flow path 120 or the bypass flow path 130 in response to the temperature set or defrosted by the user. In the present disclosure, mixed air is formed in response to the temperature in the defrosting operation via the cooling flow path 120 and the bypass flow path 130, and the switching door(s) 400 are switched to a fully opened state so that the mixed air is introduced into the second flow path or the second flow paths 200. Air having a predetermined temperature in the housing 2 is discharged to the inner surface of the vehicle window through the second outlet port or ports 210 via the opened switching door(s) 400. Furthermore, the amount of air flowing through the cooling flow path 120 may be adjusted by controlling the first temperature door 141 and the second temperature door 142 depending on the temperature set in the defrosting operation.Further, in the defrosting operation, each switching door 400 is rotated to fully open the respective second flow path 200 and controlled to discharge the maximum discharge amount through the corresponding second discharge port 210.According to the present disclosure, FIG. 5 is a diagram illustrating a mixed air flow having different temperatures, the mixed air being discharged to the first discharge ports 110 located at the left and right sides of the orifice 150, respectively.In the illustrated range, an outlet port temperature of the first outlet port 110 disposed on the left side of the orifice 150 and an outlet port temperature of the second outlet port 110 disposed on the right side of the orifice 150 are set to be different from each other. Here, the temperature of the air discharged through the first discharge port 110 disposed on the right side of the orifice 150 is set to a low value.Accordingly, the temperature flap 140, i.e., the first temperature flap 141 and the second temperature flap 142, is controlled such that an amount of air introduced into the first sub flow path 101 disposed on the left side of the orifice 150 is smaller than an amount of air introduced into the second sub flow path 102 disposed on the right side of the orifice 150.Here, the temperature flap 140 is adjacent to the blower 10 and is disposed between the first flow path 100 and the blower 10. Moreover, the temperature flap 140 facing the first outlet opening 110 includes the first temperature flap 141 that integrally controls an opening amount of the first sub flow path 101 disposed on the left side of the orifice 150 and an opening amount of the bypass flow path 130 disposed adjacent to the first sub flow path 101, and includes the second temperature flap 142 that integrally controls an opening amount of the second sub flow path 102 disposed on the right side of the orifice 150 and an opening amount of the bypass flow path 130 disposed adjacent to the second sub flow path 102.The first temperature flap 141 is configured to control an amount of air introduced into the first sub flow path 101 by the blower 10 and an amount of air introduced into the bypass flow path 130 adjacent to the first sub flow path 101. Therefore, when the temperature of the air discharged from the left side of the housing is relatively low, the first temperature door 141 is controlled so that a flow rate of the air introduced into the first sub flow path 101 becomes small and a flow rate of the air introduced into the bypass flow path 130 becomes large.Moreover, the bypass flow path 130 may be configured to include a heating wire part 300. In particular, the heating wire part 300 can be configured as a PTC heater. Accordingly, current may be applied to the heating wire part 300 disposed in one of the bypass flow paths 130 on the left and right sides, the one bypass flow path 130 having a high target temperature.Conversely, an air flow on the right side of the housing 2 will be described with the outlet temperature set to be low. The amount of air introduced into the second bypass flow path 102 by the blower 10 and flowing through the evaporator 20 is controlled to exceed an amount of air flowing through the sub flow path 130.In other words, the second temperature flap 142 is configured to integrally control an amount of air introduced into the second sub flow path 102 by the blower 10 and an amount of air introduced into the bypass flow path 130 adjacent to the second sub flow path 102. Accordingly, the second temperature flap 142 is controlled so that the amount of air introduced into the second sub flow path 102 is larger than the amount of air introduced into the second sub flow path 130 adjacent to the second sub flow path 102.Accordingly, the temperature of the air discharged from the first discharge port 110 on the right side of the orifice 150 may be lower than the temperature of the air discharged from the first discharge port 110 on the left side of the orifice 150.As should be apparent from the above description, the present disclosure can achieve the following effects through the embodiments, a combination of the above-described configurations, and an intermediate use relationship.With the present disclosure, there is provided a roof air conditioner of which the outlet temperature is set in response to a request of a user.Moreover, the present disclosure provides various air conditioners that are respectively disposed at the opposite ends of the roof air conditioner, inserted into a roof of the vehicle interior, and separated by a panel, thereby achieving convenience for the user.Further, the roof air conditioner may separately or simultaneously supply air to a first outlet port through which an occupant compartment of the vehicle is supplied with air and to a second outlet port facing the vehicle window, resulting in improvement in economy.The present disclosure has been described in detail with reference to various embodiments, and the present disclosure may be used in various other combinations, modifications, and environments. In other words, it should be understood by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the appended claims and their equivalents.
