Description

Technical Field

[0001] The present invention relates to a roof air conditioning device, and more particularly to the following type of roof air conditioning device which is installed in a roof and configured to selectively discharge conditioned air. Background Art

[0002] A vehicle air conditioning device provided as part of a vehicle is configured to cool or heat the interior of the vehicle in summer or winter and / or is configured to remove frost on a windshield in rainy or winter weather, thereby ensuring a forward and backward view for a driver. The air conditioning device is generally equipped with a heating system and a cooling system and selectively introduces (i.e., sucks in) outside air or inside air. Thereafter, the introduced air is heated or cooled and blown into the vehicle interior, thereby cooling, heating the vehicle interior or ventilating it.

[0003] A general vehicle air conditioning device is usually a front air conditioning device, and air for cooling or heating is configured to be discharged from an air outlet formed in a dashboard at a front end of the vehicle interior. For a vehicle having a large interior space, such as a luxury sedan or an SUV, an existing air conditioning device may not provide sufficient cooling or heating air for rear seats.

[0004] To solve the above problems, in the case of a vehicle having a large interior space, a rear seat type air conditioning device or a roof type air conditioning device installed on the roof can be used. The roof type air conditioning device is configured to discharge air conditioning air above the heads of vehicle passengers and is installed separately, thereby contributing to the cooling and heating performance of rear seats.

[0005] In a conventional design related to a roof type air conditioning device for a vehicle, the roof type air conditioning device includes a plurality of air passages provided in a part of a space in a box or a housing installed on the roof. Each air passage may include a condenser, an evaporator, and a fan. The roof type air conditioning device further includes a refrigerant circulation system which is provided in a separate space in the box or the housing and is configured to circulate a refrigerant using the condenser and the evaporator.

[0006] In addition, another air passage is configured to cool air introduced from the vehicle interior through the evaporator by forced air blown from a crossflow fan and perform a cooling function and an air conditioning function by discharging air from the roof.

[0007] When the roof type air conditioning device is installed on the roof, the size of the roof increases. This not only directly affects the interior and exterior appearance of the vehicle, but may also affect the driving performance of the vehicle.

[0008] A roof-mounted air conditioning device in the related prior art has a cross-flow fan applied thereto. Therefore, the length of the roof-mounted air conditioning device increases in the vertical direction, making it difficult to install the roof-mounted air conditioning device on the roof. Here, even if the roof-mounted air conditioning device is installed outside the roof, the height of the vehicle increases. Therefore, the roof-mounted air conditioning device can be installed on large buses, but it is difficult to install the roof-mounted air conditioning device on passenger cars and trucks.

[0009] In addition, since the roof-mounted air conditioning device is configured to discharge only the cooled and heated air into the vehicle interior, it is difficult to provide an additional discharge port for dehumidifying the front and rear window glasses of the vehicle.

[0010] The above information disclosed in this background art section is only for enhancing the understanding of the background of the present invention. Therefore, the background art section may contain information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0011] The present invention is dedicated to solving the above problems related to the prior art.

[0061] Hereinafter, embodiments will be described in detail with reference to the drawings. When describing the embodiments with reference to the drawings, throughout the description and the drawings, the same reference numerals are used to denote the same or corresponding components, and repeated descriptions are omitted.

[0062] Figure 1 is a schematic diagram showing a roof air - conditioning device 1 located respectively at or near the front end and the rear end of a vehicle passenger compartment according to an embodiment of the present invention. Figure 2 is a schematic diagram showing the structure of a first discharge port 110 and a second discharge port 210 of the roof air - conditioning device 1. In addition, Figure 3 is a schematic diagram showing the positional relationship of the components of the roof air - conditioning device 1.

[0063] The roof air - conditioning device 1 of the present invention is inserted into the roof of the vehicle in a state of being adjacent to the front windshield or the rear windshield (i.e., the glass of the vehicle). The roof air - conditioning device 1 is configured to include a plurality of flow paths formed in a housing 2. At least one flow path can also be configured to include a plurality of sub - flow paths.

[0064] The first row of outlets 110 is fluidly connected to the first flow path 100 and is located at one end of the roof air conditioner 1. The second row of outlets 210 is fluidly connected to the second flow path 200 and is located at the other end of the roof air conditioner 1. In this example, the roof air conditioner 1 has two such first row of outlets 110 and two such second row of outlets 210, and each type of row of outlets of the roof air conditioner may be more or less than two. In addition, the cooling air or the heating air in the housing 2 is configured to be discharged through the first row of outlets 110 into the vehicle passenger compartment and towards the passengers or seats. The cooling air or the heating air in the housing 2 is also configured to be discharged through the second row of outlets 210 to the inner side of the glass. The first row of outlets 110 has flaps, i.e., vanes (not shown) provided therein. One of the vanes (left vane) is located on the left side of a partition, a partition wall, a blind plate, etc., i.e., on the left side of the blind plate 150 in the housing 2, and the other vane (right vane) is located on the right side of the blind plate 150. In one example, the left and right vanes can be independently controlled, and the temperature and discharge direction of the air discharged from the left side of one row of outlets and the temperature and discharge direction of the air discharged from its right side can be set independently of each other.

[0065] In addition, the roof air conditioner 1 includes a blower 10 located at one end of the housing 2. The housing 2 and the blower 10 are configured to introduce the air in the passenger compartment or the air supplied from the outside therein. In this example, the blower 10 is located in the vertical direction of the housing 2 and is configured to have a fan shape. In addition, according to an embodiment of the present invention, the blower 10 may include a fan, such as a sirocco fan, which is arranged such that the air outside the housing 2 is sucked into 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.

[0066] In the housing 2, the evaporator 20 is located 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. In addition, the roof air conditioner 1 includes a blind plate 150, which is located in the first flow path 100 and is configured to divide the cooling flow path 120 of the first flow path 100 into two sub-flow paths 101 and 102. The blind plate 150 is formed integrally with the housing 2 and is in a state of passing through the evaporator 20. Therefore, the air introduced into each of the sub-flow paths 101, 102 is configured to pass through at least a part of the evaporator 20.

[0067] In other words, the first flow path 100 includes a cooling flow path 120 which is configured to discharge air through the cooling flow path via the evaporator 20; and a bypass flow path 130 which is configured to discharge air through the bypass flow path when bypassing the evaporator 20. In addition, the cooling flow path 120 includes a first sub-flow path 101 and a second sub-flow path 102, and each sub-flow path is obtained by dividing the cooling flow path 120 into two sub-flow paths by using a blind plate 150. Specifically, the blind plate 150 divides the cooling flow path 120 into a left side and a right side.

[0068] In this way, the first flow path 100 of the present invention includes a cooling flow path 120 passing through the evaporator 20 and a bypass flow path 130 bypassing the evaporator 20. The cooling flow path 120 includes a first sub-flow path 101 and a second sub-flow path 102, and each sub-flow path is obtained by dividing the cooling flow path 120 into two sub-flow paths by using a blind plate 150.

[0069] The temperature door 140 is rotatably arranged in the housing 2 and is located between the first flow path 100 and the blower 10. In addition, 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 door 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 can be different from each other. In other words, the temperature door 140 can be configured to separately control the opening amount of the cooling flow path 120 and the opening amount of the bypass flow path 130.

[0070] In an embodiment of the present invention, the temperature doors 140 on the left side and the right side of the blind plate 150 can be independently controlled. Each temperature door 140 includes a flap which is configured to have different angles with respect to the central axis passing through the housing 2, that is, to be arranged at different angles with respect to the central axis. In addition, the flaps corresponding to the respective sub-flow paths 101 or 102 and the flaps corresponding to the respective bypass flow paths 130 adjacent to the sub-flow paths are configured to form an angle of 90 degrees therebetween. Therefore, when the sub-flow path 101 or 102 is opened, the corresponding bypass flow path 130 can be closed, and when the bypass flow path 130 is opened, each of the sub-flow paths 101 or 102 can be switched to the closed state. In addition, the central axis carrying the flaps can be rotated to open the sub-flow path 101 or 102 and the corresponding bypass flow path 130. This enables the opening amount of the temperature door 140 to be adjusted.

[0071] In one embodiment of the present invention, the temperature door 140 may include a first temperature door 141 and a second temperature door 142, and a blanking plate 150 is located at the center between the two. In other words, one of the temperature doors 141 or 142 can overall control the opening and closing of each sub-flow path 101 or 102 and the bypass flow path 130 of the adjacent sub-flow path. In one embodiment of the present invention, a temperature door 140 is provided on each of the left side (temperature door 141) and the right side (temperature door 142) of the blanking plate 150.

[0072] In this way, through the first temperature door 141, when the first sub-flow path 101 is fully opened, the bypass flow path 130 located near the first sub-flow path 101 remains in a fully closed state. In addition, through the second temperature door 142, when the second sub-flow path 102 is fully opened, the bypass flow path 130 located near the second sub-flow path 102 is switched to a fully closed state.

[0073] The switch door 400 is located at the branch position of the first flow path 100 and the second flow path 200, and the switch door 400 is arranged adjacent to the first discharge port 110 to control the opening and closing of the second flow path 200 and the opening and closing of the first discharge port 110. The switch door 400 can be controlled to open the first discharge port 110 and close the second flow path 200 when cooling or heating the vehicle cabin is required. In addition, when dehumidifying the glass, the switch door 400 can be controlled to open the second flow path 200 and close the first discharge port 110.

[0074] The switch door 400 located between the first flow path 100 and the second flow path 200 and the switch door 400 located at the inner end of the first discharge port 110 can be respectively controlled as a whole. In addition, the switch door 400 located at the inner end of the first discharge port 110 can be divided into a left switch door 400 and a right switch door 400, and a blanking plate 150 is located at the center between the two. The left switch door 400 and the right switch door 400 can be independently controlled in response to the temperature setting in the vehicle cabin. In addition, the switch door 400 located between the first flow path 100 and the second flow path 200 may include switch doors 400 on each side of the housing 2, because in the illustrated embodiment, there are first and second flow paths 100, 200 on each side of the roof air conditioning device 1.

[0075] The roof air conditioner 1 includes a second flow path 200 which is formed to branch out from the first flow path 100, located on opposite sides of the first flow path 100 respectively, and is configured to perform defrosting. The switch doors 400 are located on opposite sides of the housing 2 respectively, and are respectively provided at the positions where the first flow path 100 and the second flow path 200 branch, and open and close integrally. Each switch door 400 provided at the branching position of the first flow path 100 and the second flow path 200 can be formed by a flap which rotates around a central axis along the height direction of the housing 2. Accordingly, in response to a user input of the defrost mode, by rotating the switch door 400 around the central axis, the second flow path 200 can be switched to the open state. With this configuration, the air introduced from the blower 10 can be discharged through the second flow path 200 to the second discharge port 210, and can be guided to flow along one side (i.e., the vehicle inner side of the glass).

[0076] In addition, the switch doors 400 located at the first discharge port 110 and separated by the blind plate 150 are divided into a left switch door 400 and a right switch door 400. The left switch door 400 and the right switch door 400 can open and close independently in response to a request from the user.

[0077] In this way, the switch doors 400 are located at the front end of the second flow path 200 and the inner part of the first discharge port 110 respectively, and each switch door 400 can be controlled to open and close independently.

[0078] Figure 4 is a schematic diagram showing the relationship between the configurations as an embodiment of the present invention, in which when the defrost mode is input, that is, when the user selects the defrost mode, the air in the housing 2 is discharged through the second discharge port 210.

[0079] The air flowing through the blower 10 moves in the housing 2 through the first flow path 100. In addition, the switch door 400 located at the branch of the first flow path 100 and configured to open and close the second flow path 200 is switched to the open state. Here, the switch door 400 formed in the first discharge port 110 can open or close in response to a request from the user.

[0080] In response to a user's setting or a defrosting temperature, the air introduced into the first flow path 100 moves through the cooling flow path 120 or the bypass flow path 130. In an embodiment of the present invention, in the defrost mode, in response to the temperature, mixed air is formed through the cooling flow path 120 and the bypass flow path 130, and the switching door 400 is switched to the fully open state so that the mixed air is introduced into the second flow path 200. By using the open switching door 400, the air having a set temperature in the housing 2 is discharged to the inner surface of the vehicle glass through the second discharge port 210. In addition, in the defrost mode, by controlling the first temperature door 141 and the second temperature door 142 according to the set temperature, the amount of air passing through the cooling flow path 120 can be adjusted.

[0081] In addition, in the defrost mode, each switching door 400 rotates to fully open the corresponding second flow path 200 and is controlled to discharge the maximum discharge amount through the corresponding second discharge port 210.

[0082] According to an embodiment of the present invention, Figure 5 is a schematic diagram showing the flow of mixed air having different temperatures, where the mixed air is discharged to the first discharge ports 110 located on the left and right sides of the blind plate 150, respectively.

[0083] In the shown area, the discharge temperature of the first discharge port 110 located on the left side of the blind plate 150 and the discharge temperature of the first discharge port 110 located on the right side of the blind plate 150 are set to be different from each other. Here, the temperature of the air discharged through the first discharge port 110 located on the right side of the blind plate 150 is configured to be lower.

[0084] Accordingly, the temperature door 140, that is, the first temperature door 141 and the second temperature door 142, is controlled such that the amount of air introduced into the first sub-flow path 101 provided on the left side of the blind plate 150 is less than the amount of air introduced into the second sub-flow path 102 provided on the right side of the blind plate 150.

[0085] Here, the temperature door 140 is adjacent to the blower 10 and is located between the first flow path 100 and the blower 10. In addition, the temperature door 140 facing the first discharge port 110 includes: a first temperature door 141 that integrally controls the opening amount of the first sub-flow path 101 located on the left side of the blind plate 150 and the opening amount of the bypass flow path 130 adjacent to the first sub-flow path 101; and a second temperature door 142 that integrally controls the opening amount of the second sub-flow path 102 located on the right side of the blind plate 150 and the opening amount of the bypass flow path 130 adjacent to the second sub-flow path 102.

[0086] The first temperature door 141 is configured to control the amount of air introduced from the blower 10 into the first sub-flow path 101 and the 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 such that the air flow rate introduced into the first sub-flow path 101 becomes smaller, while the air flow rate introduced into the bypass flow path 130 becomes larger.

[0087] In addition, the bypass flow path 130 may be configured to include a heating wire part 300. More specifically, the heating wire part 300 may be configured as a PTC heater. Therefore, power can be applied to the heating wire part 300 in one of the bypass flow paths 130 located on the left and right sides, where the one bypass flow path 130 has a high set temperature.

[0088] On the other hand, a description will be given of the air flow on the right side of the housing 2 where the discharge temperature is set to be low. The amount of air introduced from the blower 10 into the second sub-flow path 102 passing through the evaporator 20 is controlled to exceed the amount of air flowing through the bypass flow path 130.

[0089] In other words, the second temperature door 142 is configured to overall control the amount of air introduced from the blower 10 into the second sub-flow path 102 and the amount of air introduced into the bypass flow path 130 adjacent to the second sub-flow path 102. Therefore, the second temperature door 142 is controlled such that the amount of air introduced into the second sub-flow path 102 is greater than the amount of air introduced into the bypass flow path 130 adjacent to the second sub-flow path 102.

[0090] Therefore, the temperature of the air discharged from the first discharge outlet 110 on the right side of the blind plate 150 can be lower than the temperature of the air discharged from the first discharge outlet 110 on the left side of the blind plate 150.

[0091] It can be clearly seen from the above description that the present invention can achieve the following effects through the embodiments, the combination of the above configurations, and the usage relationship between them.

[0092] The present invention provides a roof air conditioner having a discharge temperature set in response to a user's request.

[0093] In addition, the present invention provides different air conditioners, which are respectively arranged at opposite ends of the roof air conditioner, inserted into the roof inside the vehicle, and separated by a blind plate, thereby having the effect of providing convenience for users.

[0094] In addition, the roof air conditioner can supply air to the first discharge outlet for supplying air to the vehicle cabin and the second discharge outlet facing the vehicle glass separately or simultaneously, thereby having the effect of improving economic efficiency.

[0095] The present invention has been described in detail with reference to various embodiments of the present invention, and the present invention can be used in various other combinations, variations, and environments.
