Description

[0001] The present invention relates to an air conditioning unit, particularly to an air conditioning unit for use on the roof of a recreational vehicle, a corresponding air conditioning system including the air conditioning unit, and a construction kit for the air conditioning unit and the air conditioning system.

[0002] Recreational vehicles are often equipped with or retrofitted with additional antennas, such as antennas for cellular connectivity, GPS (Global Positioning System) antennas, or WiFi antennas, to provide wireless internet access inside the vehicle. Known solutions require modification or drilling into the roof of the recreational vehicle to install the system. By modifying the roof accordingly, the risk of water leakage and condensation spreading from the exterior of the vehicle to the interior increases. Furthermore, antenna systems often have sections that protrude upwards from the top of the roof, requiring space and being exposed to external weather conditions.

[0003] The present invention aims to provide a solution to the above-mentioned problems, and the overall concept of the solution is to install the antenna or antenna module inside the air conditioning unit.

[0004] Accordingly, as a first aspect, the present invention provides an air conditioning unit configured to be installed on a vehicle, particularly on the exterior of the vehicle, wherein the air conditioning unit is configured such that an antenna connected to an antenna cable can be removably installed in the air conditioning unit.

[0005] This allows for the modification of antennas for air conditioning units on the user side, as well as the replacement and upgrading of antennas as communication technology performance improves. Furthermore, the vehicle roof antenna requires no additional space and is unaffected by external conditions.

[0006] According to a preferred embodiment, the air conditioning unit includes a housing that spatially separates the interior of the air conditioning unit from the environment, and an antenna can be disposed within the housing. Preferably, the housing is configured such that it can be opened by a user using standard household tools (such as a screwdriver). This allows the user easy access to the interior of the air conditioning unit.

[0007] According to a preferred embodiment, the air conditioning unit includes a housing located inside the housing, the housing forming an air duct that serves as at least part of a first air circuit within the air conditioning unit, and an antenna can be arranged between the housings. This provides space for the antenna between the housings. This makes antenna installation easy, as in the simplest way, the antenna can simply be clamped between the housings.

[0008] Preferably, the housing has a receiving area for the antenna on its outer surface. The receiving area is shaped to match the antenna's profile to accommodate it. This further simplifies antenna installation or assembly. The antenna can be simply placed in the appropriate position within the receiving area, and then the housing can be closed.

[0009] More preferably, the housing has a guiding device on its outer surface for guiding the antenna cable. The guiding device for the cable preferably extends from the receiving area along the outer surface of the housing. Preferably, the guiding device has the form of a groove adapted to receive the antenna cable.

[0010] There are no particular limitations on the material of the outer shell. However, according to a preferred embodiment, the outer shell is formed of a plastic foam material. This results in a relatively light weight. Furthermore, plastic foam materials (like expanded polystyrene, expanded polypropylene, and similar materials) are sufficiently stable for this purpose. In addition, plastic foam materials (like expanded polystyrene, expanded polypropylene, and similar materials) have thermal insulation properties, which is particularly advantageous if the first air circuit is an air circuit for the vehicle's interior air. More preferably, the plastic foam material comprises or is composed of expanded polypropylene. Using expanded polypropylene allows for high rigidity, and components made of expanded polypropylene have high durability. This is particularly advantageous for housing areas and guiding devices.

[0011] According to a preferred embodiment, the air conditioning unit includes an antenna. In this embodiment, the antenna is actually formed part of the air conditioning unit. However, the air conditioning unit is still configured such that the antenna can be removed and / or replaced by the user.

[0012] In a particularly preferred embodiment of the air conditioning unit including an antenna, the antenna is included in an assembly that further includes a signal transmitter, such as a WiFi router. In this case, the antenna cable is simply a power cable, since all other necessary electronic components for receiving and transmitting electronic signals are arranged within the assembly including the antenna. Preferably, the assembly has an enclosure, which makes it easier to transport as a single unit. More preferably, the power cable is connected to a power source inside the air conditioning unit, which is configured to provide power to the assembly. More preferably, the air conditioning unit includes a controller, preferably a remote control, wherein the antenna and the signal transmitter can be controlled by the controller of the air conditioning unit.

[0013] As a second aspect, the present invention provides an air conditioning system for a vehicle, the air conditioning system including an air conditioning unit of the present invention and an air distribution unit configured to be installed inside the vehicle and connected to the air conditioning unit. Through the air distribution unit, conditioned air from the air conditioning unit can be distributed inside the vehicle. According to the second aspect, the air distribution unit is configured to receive an antenna cable. Preferably, a user can access the antenna cable from inside the vehicle using a standard household tool such as a screwdriver. This allows the user easy access to the antenna cable.

[0014] According to a preferred embodiment, the air distribution unit includes a mounting area for mounting a signal transmitter (e.g., a WiFi router and / or other suitable components). The air distribution unit is configured such that the signal transmitter can be connected to an antenna cable. Therefore, in particular, the signal transmitter can be easily mounted from inside the vehicle, thereby providing an antenna signal within the vehicle. Preferably, the mounting area includes a snap-fit ​​element through which the signal transmitter can be mounted. In this way, the signal transmitter can be easily embedded into place at the air distribution unit.

[0015] Preferably, the air distribution unit includes a removable cover that conceals the installation area. This allows a signal transmitter, including appropriate cabling, to be installed in a location out of the user's sight.

[0016] According to a preferred embodiment, the air conditioning system includes a signal transmitter. Now, the signal transmitter is actually part of the system, but the air distribution unit is still configured such that the signal transmitter can be removed and / or replaced by the user.

[0017] According to a preferred embodiment of the air conditioning system, in the installed state, the air conditioning unit is connected to a power source, wherein the antenna and signal transmitter can also be connected to the power source of the air conditioning unit. This facilitates plug-and-play functionality.

[0018] According to a preferred embodiment, the air conditioning system includes a controller, wherein the antenna and signal transmitter can be controlled by the air conditioning system's controller. This simplifies operation because fewer control devices (like a remote control) are required.

[0019] As a third aspect, the present invention provides a construction kit including an antenna and an antenna cable configured for installation in an air conditioning unit or system according to the invention. The construction kit allows for easy upgrades to the air conditioning unit and system. Preferably, the construction kit further includes a signal transmitter (e.g., a WiFi router) configured for installation within the air distribution unit of the air conditioning system of the present invention.

[0040] Figure 20 yes Figure 19 A side view of the installed air conditioning system shown.

[0041] In the accompanying drawings and the following detailed description, the same components of the first and second embodiments of the air conditioning unit are assigned the same reference numerals. However, the reference numerals for corresponding components of the first and second embodiments of the air conditioning unit, which are different from each other in specific design, are additionally marked with the letters A and B, where "A" refers to the first embodiment and "B" refers to the second embodiment of the air conditioning unit.

[0042] Within the scope of this invention, terms related to orientations or directions such as front, rear, side, bottom, and top refer to the air conditioning unit or system when mounted on the roof of the vehicle and relative to the vehicle's direction of travel, unless otherwise explicitly stated.

[0043] Figure 1 The appearance of the air conditioning unit 1 is shown from the rear (top left), side (top right), and bottom (bottom right). In fact, the entire air conditioning unit 1 is covered by the housing 2. The housing 2 has two parts, the upper part being a cover 25, which can be removed to open the air conditioning unit 1 and is also in an installed state, for example, on the roof 110 of a vehicle. Figure 19 As shown. The lower part of the housing 2 is the base 26, in which most of the internal components of the air conditioning unit 1 are arranged.

[0044] Typically, such an air conditioning unit 1 has two separate air circuits: an interior vehicle air circuit and an ambient air circuit. Within the scope of this invention, the air circuit for the interior vehicle air is designated as the first air circuit, and the air circuit for the ambient air is designated as the second air circuit.

[0045] For the first air circuit, the air conditioning unit 1 has a first opening 20 and a second opening 21 on its lower side. The first opening 20 serves as an inlet for air inside the vehicle. The second opening 21 serves as an outlet for conditioned air to be returned to the vehicle interior. Therefore, the connection area 24 provides a sealed connection between the air conditioning unit 1 and the roof 110. To properly distribute the conditioned air inside the vehicle, the first opening 20 and the second opening 21 are connected to an air distribution unit 100 installed inside the vehicle, as will be referred to below. Figure 19 and Figure 20 Further detailed explanation.

[0046] For the second air circuit, the air conditioning unit 1 has a first vent 22 on its side. The first vent 22 serves as an inlet for ambient air. The second vent 23 is located at the rear of the air conditioning unit 1. The second vent 23 serves as an outlet for ambient air.

[0047] Figure 2 A first embodiment of the air conditioning unit 1 is shown, wherein the cover 25 of the housing 2 is removed. The first embodiment of the air conditioning unit 1 includes a specific fan arrangement 5 (first fan arrangement). The first fan arrangement 5 is essentially composed of a common motor 13 driving two fans, one fan in each of the first and second air circuits.

[0048] An outer casing 16 is arranged on the base portion 19 inside the air conditioning unit 1. The outer casing 16 internally forms an air duct that serves as part of a first air circuit. The outer casing 16 is formed of expanded polypropylene, which has good thermal insulation properties and is a very lightweight material. The outer casing 16 is composed of three molding portions (i.e., a first molding portion 17A, a second molding portion 18A, and a third molding portion 27). The outer casing 16 is located at the front of the air conditioning unit 1. The second molding portion 18A and the first molding portion 17A are held together and positioned by the housing 2. Specifically, the second molding portion 18A is held in position by the cover portion 25 of the housing 2.

[0049] The first molding portion 17A and the second molding portion 18A are connected to the third molding portion 27. The third molding portion 27 is mounted at the base portion 19 in the evaporator 3 region. The housing 16 thus forms an air duct representing the entire first air circuit inside the air conditioning unit 1. Since the evaporator 3 is not intended to be replaceable like the fan arrangements 5 and 6, the third molding portion 27 remains the same in both the first and second embodiments of the air conditioning unit 1. Each of the first molding portion 17A, the second molding portion 18A, and the third molding portion 27 is formed of expanded polypropylene.

[0050] The condenser 4 is located at the rear of the air conditioning unit 1. The condenser 4 is enclosed by a condenser housing 30. The condenser housing 30 is also made of expanded polypropylene and is open at its front and rear to allow air passage. The front opening 31 is circular to match the impeller 11A (the second impeller of the first fan arrangement). The condenser is cooled by ambient air, which is drawn in through the first vent 22 and guided to the condenser 4 by the second fan 10A of the first fan arrangement 5. The second fan 10A is driven by a common motor 13. Hot air is exhausted through the second vent 23 and guided back into the environment.

[0051] exist Figure 3 In this configuration, the second molding portion 18A is lifted upwards. Therefore, the interior of the housing 16 is visible. As described above, the housing 16 forms a first air circuit and thus houses the evaporator 3 of the air conditioning unit 1 for cooling the vehicle's interior air. Airflow in the first air circuit is generated by the first fan 7A of the first fan arrangement 5. The first fan 7A includes a first impeller 8A and a first shaft 9A, the first impeller 8A rotating about the first shaft by the driving force of a common motor 13. The first impeller 8A of the first fan arrangement 5 is enclosed by the housing 16. Specifically, the first impeller 8A is enclosed by the first molding portion 17A and the second molding portion 18A of the housing 16.

[0052] The first fan 7A of the first fan arrangement 5 is a centrifugal fan that discharges air radially relative to its axis of rotation. The second fan 10A of the first fan arrangement 5 is an axial fan. As described above, the first fan 7A and the second fan 10A of the first fan arrangement 5 are driven together by a common motor 13. The common motor 13, the first fan 7A, and the second fan 10A together form the first fan arrangement 5 provided with the air conditioning unit 1.

[0053] Figure 4This is a plan view showing the base 26 of the housing 2. Here, it can be determined that the first shaft 9A and the second shaft 12A of the first fan arrangement 5 are arranged collinearly with respect to each other. A common motor 13 is fixed to the base portion 19 of the base 26. The base 26 is equipped with multiple threaded holes for fixing multiple components. For better generalization, several of the aforementioned components not closely related to the invention are not shown in the figure, which is why some fixing devices on the base portion are not occupied but are visible in the figure.

[0054] Furthermore, in Figure 4 In this configuration, the upper edge of the first molded portion 17A of the housing 16 can be determined. The first shaft 9A passes through the connection area between the first molded portion 17A and the second molded portion 18A of the housing 16. Therefore, the first impeller 8A is completely enclosed within the first air circuit. The electronic control unit 40 is also integrated into the first air circuit. The electronic control unit 40 is specifically located upstream of the evaporator 3, near the inlet for the interior vehicle air. This ensures a constant and moderate temperature for the control unit 40.

[0055] exist Figure 5 In the diagram, the airflow in the first and second air circuits is indicated by arrows. For the vehicle's interior air, air enters the first air circuit through the first opening 20 and flows around and past the evaporator 3. The coolant in the evaporator 3 is now heated and evaporated, extracting heat energy from the air, thus cooling it. The first fan 7A then draws in the cooled air axially and exhausts it radially through the blades of the first impeller 8A. To prevent the exhaust and intake air from mixing again, an air duct formed by the first molding portion 17A and the second molding portion 18A is fitted to the periphery of the first impeller 8A on the intake side (i.e., the distal end of the first impeller 8A relative to the common motor 13). After being radially exhausted by the first fan 7A, the air is guided downwards and returned to the vehicle interior through the second opening 21.

[0056] For ambient air, it enters the second air circuit through the first vents 22 on both lateral sides of the air conditioning unit 1. The ambient air is guided to the second fan 10A of the first fan arrangement 5. The second impeller 11A is fitted into the front opening 31 of the condenser housing 30 to effectively and efficiently force the ambient air to flow around the condenser 4. In the condenser 4, the vaporous coolant is cooled and condensed by the ambient air, which is then heated. The heated air is finally discharged back into the environment through the second vent 23 located at the rear of the air conditioning unit 1.

[0057] exist Figure 6The assembly of the first fan arrangement 5 with the first molding portion 17A and the second molding portion 18A of the housing 16 is shown. Thus, when the first fan arrangement 5 is installed into the air conditioning unit 1, the first molding portion 17A is installed inside the air conditioning unit 1 onto the base portion 19 of the housing 2. Next, the first fan arrangement 5 is installed onto the base portion 19. Consequently, the first impeller 8A of the first fan 7A is fitted into the cavity of the first molding portion 17A. Finally, the second molding portion 18A is placed from above onto the first molding portion 17A and the third molding portion 27. Therefore, the second molding portion 18A is the cover that ultimately establishes the first air circuit during the formation of the housing 16. The second molding portion 18A has a cavity that encloses the upper part of the first impeller 8A of the first fan 7A of the first fan arrangement 5.

[0058] When installation is complete, the cover 25 of the housing 2 is placed on the base 26 of the housing 2, thereby sealing the air conditioning unit 1. The cover 25 secures the second molding portion 18A from moving upward, thereby keeping the outer casing 16 together.

[0059] Figure 6 The replaceability of the fan arrangement installed in the air conditioning unit 1 is further demonstrated. The first fan arrangement 5, having a shared motor 13 for both the first fan 7A and the second fan 10A, may not have sufficient power, performance, or be too noisy for the user. Therefore, the user may upgrade the air conditioning unit 1 by removing the first fan arrangement 5 and installing another fan arrangement with different characteristics and performance to meet the user's needs, instead of referencing and implementing a completely new air conditioning unit. An example of such an upgraded fan arrangement with different characteristics and performance is the second fan arrangement 6, whose assembly is shown in... Figure 7 middle.

[0060] The second fan arrangement 6 includes a first fan 7B and a second fan 10B. In the second fan arrangement, each of the first fan 7B and the second fan 10B is equipped with a separate motor, with the first motor 14 driving the first fan 7B and the second motor 15 driving the second fan 10B. The first motor 14 and the second motor 15 are controlled separately and can therefore be driven more effectively and efficiently according to the needs of the environment and the user.

[0061] Similar to the first fan arrangement 5, the first fan 7B of the second fan arrangement 6 is designed to generate airflow in the first air circuit to enhance heat exchange between the air flowing in the first air circuit and the evaporator 3. Therefore, the isolation housing 16 encloses the first impeller 8B of the first fan 7B of the second fan arrangement 6.

[0062] The assembly of the second fan arrangement 6 is similar to that of the first fan arrangement 5. For example... Figure 6As shown, after the removable parts of the first fan arrangement 5 and its housing 16 have been removed, the first molding part 17B, the second molding part 18B, and the second fan arrangement 6 are installed by mounting the first molding part 17B inside the air conditioning unit 1 to the base portion 19 of the base portion 26 of the housing 2. Next, the second fan 10B is installed together with the second motor 15 of the second fan arrangement 6 to the base portion 19. The first fan 7B of the second fan arrangement 6 is integrally installed with the first motor 14 in the cavity of the first molding part 17B. Finally, the second molding part 18B is placed above the first molding part 17B and the third molding part 27. Therefore, the second molding part 18B serves as a cover that ultimately establishes the first air circuit during the formation of the housing 16. The second molding part 18B has a cavity that encloses the upper part of the first impeller 8B of the first fan 7B and serves the cavity of the first motor 14 of the second fan arrangement 6.

[0063] When installation is complete, the cover 25 of the housing 2 is placed on the base 26 of the housing 2, thereby sealing the air conditioning unit 1. The cover 25 thereby fixes the second molding portion 18B to prevent it from moving upward, thus keeping the outer casing 16 together.

[0064] Similar to Figure 4 , Figure 8 A perspective plan view of the base 26 of the housing 2 according to a second embodiment of the air conditioning unit 1 is shown. In the second embodiment of the air conditioning unit 1, a second fan arrangement 6 is installed. As described above, the second fan arrangement 6 consists of two separate components, one of which includes a first fan 7B and a first motor 14, which is completely enclosed by the housing 16. The motor 14 is mounted via a mounting plate on a region inside the first air circuit of the first molding portion 17B. The first fan 7B, or correspondingly the first impeller 8B of the first fan 7B, is a centrifugal fan that draws air in axially from both sides (the distal and proximal sides of the first impeller 8B relative to the motor). In these positions, the first molding portion 17B and the second molding portion 18B are configured such that the air discharged radially from the first impeller 8B no longer mixes with the previously drawn-in air.

[0065] The second fan 10B of the second fan arrangement 6 is very similar to the second fan 10A of the first fan arrangement 5, except that the second fan of the second fan arrangement 6 is equipped with a separate motor, namely the second motor 15. The second fan 10B and the second motor 15 form another component of the two separate components of the second fan arrangement 6. The second motor 15 is fixed to a mounting bracket, which is mounted on the base portion 19.

[0066] Figure 9Arrows indicate the air flowing through the first and second air circuits when the air conditioning unit 1 is operating. Regarding ambient air, the airflow is the same as in the first embodiment. Air enters the second air circuit through the first vents 22 on both lateral sides of the air conditioning unit 1. The air is directed to the second fan 10B of the second fan arrangement 6. The second impeller 11B is fitted into the front opening 31 of the condenser housing 30 to effectively and efficiently force air to flow around the condenser 4. The heated air, heated by the condenser, is finally discharged back into the environment through the second vent 23 at the rear of the air conditioning unit 1.

[0067] For the vehicle's interior air, air enters the first air circuit through the first opening 20 and flows around and passes through the evaporator 3. Heat energy is extracted from the air, thus cooling it. Then, the first fan 7B axially draws in the cooled air from both sides, as described above. The air is discharged radially through the blades of the first impeller 8B. To prevent exhaust and intake air from mixing again, air ducts formed by the first molding portion 17B and the second molding portion 18B are fitted to the periphery of the first impeller 8B at the two intake sides (i.e., the distal and proximal ends of the first impeller 8A relative to the first motor 14). After being discharged radially by the first fan 7B, the air is guided downwards and returned to the vehicle through the second opening 21.

[0068] The air conditioning unit 1 according to the first embodiment is shown in Figure 10 In, among them, Figures 10 to 16 The installation of the connecting hub 50 is demonstrated. As the first step in the installation, the second molded section 18A is removed. This exposes the first air circuit. In the wall of the third molded section 27, the cover insert 61 is positioned and arranged to cover the cutout area 60. Figure 4 , Figure 5 and Figure 8 The cut-out area 60 is best seen in the center, where the cover insert 61 is not shown. (As...) Figure 11 As shown, the cover insert 61 is removed from the cut-out area 60 by lifting it upwards. Guide rails and grooves formed at various locations assist in inserting and removing the cover insert 61 from the cut-out area 60. The cover insert 61 is also formed of expanded polypropylene material.

[0069] like Figure 12As shown, as a next step, another cover insert 61 of a different shape is reinserted into the cut-out area 60. This particular cover insert 61 has a through hole 62. The through hole 62 is designed for routing a cable from the outside of the air conditioning unit 1 through the cover insert 61 to the inside of the air conditioning unit. The through hole 62 is equipped with a rubber gasket to provide a seal. Therefore, no air leaks out of the first air circuit.

[0070] After the cable (not shown) is installed, adjacent to the cover insert 61, the cable guide 65 is placed inside the air duct of the first air circuit formed by the third molding part 27. The cable guide 65 protects the cable from damage and prevents the cable from moving around due to airflow and vibration. The cable (not shown) is routed to the outside through the vent 22 on the side of the base 26 of the housing 2.

[0071] The hub 50 has four ports 52, which are configured and designed to accept cables passing through it, such as... Figure 13 The best determination is made in the middle. Each port 52 is connected to a cable conduit 51 that guides the cable from the port 52 to the vent 22 in the housing 2. The cable conduits 51 are spaced apart from each other such that each cable conduit 51 points into the slot of the vent 22. Figure 13 In the installation steps shown, the hub is attached and secured to the housing via the connection device 53, and then the result is as follows: Figure 14 As shown. The cable (not shown) is now, for example, guided from inside the vehicle through the first opening 20, then by the cable guide 65 to the through hole 62 in the cover insert 61 and through the vent 22, through the cable conduit 51, and out from the port 52 of the connecting hub 50. The housing 16 is then closed again by placing the second molding portion 18A on the first molding portion 17A, as shown. Figure 15 As shown. Finally, the air conditioning unit 1 is closed by the cover 25 of the housing 2, as... Figure 16 As shown.

[0072] exist Figures 17 to 20 Referring again to the first embodiment of the air conditioning unit 1, it is shown that the antenna 80 is mounted into the air conditioning unit 1. The second molding portion 18A, formed of expanded polypropylene, has a receiving region 81 for the antenna 80. The receiving region 81 is formed in the upper portion of the second molding portion 18A. The antenna 80 is placed in the receiving region 81, as... Figure 18As shown. The external shape of the antenna 80 is thus adapted to the shape of the receiving region 81, or vice versa. Therefore, the antenna 80 is assembled into the receiving region 81. Furthermore, the second molding portion 18A has a groove 82 for guiding one or more cables (not shown) of the antenna 80 from the receiving region 81 to the connection area between the second molding portion 18A and the third molding portion 27. The cables are guided into the interior of the first air circuit and further through the first opening 20 (not shown here).

[0073] One or more cables (not shown) are further guided into the vehicle interior to the air distribution unit 100, such as... Figure 19 As shown. The air distribution unit 100 is mounted to the roof 110 inside the vehicle. Cooled air can be distributed into the vehicle interior via the air distribution unit 100 through the side outlets 102. The side outlets are adjustable, allowing the user to adjust the air distribution according to their needs. Inside the air distribution unit 100, concealed by a cover 101, one or more cables of the antenna 80 can be connected to a signal transmitter, such as a WiFi router (not shown). The air distribution unit 100, covered by the cover 101, has a mounting area (not shown) for mounting the signal transmitter. Furthermore, the signal transmitter is connected to the vehicle's power supply to allow the air conditioning unit 1 to receive power.

[0074] Figure 20 Finally, an easily assembled air conditioning system was demonstrated, including an air conditioning unit 1 that is again closed by a cover 25 of the housing 2 and an air distribution unit 100 that is mounted from the side to the roof 110 of the vehicle.

[0075] It should be noted that in describing the features of the connecting hub 50 and / or antenna 80, reference was made to the first embodiment of the air conditioning unit 1, wherein these features are also applicable to the second embodiment of the air conditioning unit 1 and are applied in the same manner as described in the first embodiment.
