Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and particularly to air conditioners and vehicles. Background Technology

[0002] Common vehicle parking air conditioners are generally designed for vehicles with limited interior space. The fan system itself requires space within the main interior area, and the layout of the indoor and outdoor air ducts also requires a certain amount of space, resulting in increased overall space requirements and greater air resistance. Furthermore, due to the constraints of slim and compact design requirements, the fan and air duct system tends to compress vertical space, which limits the overall cooling capacity and is detrimental to the stability and reliability of the entire unit. Summary of the Invention

[0003] The main objective of this invention is to propose an air conditioner and vehicle, which introduces a new air duct layout and indoor / outdoor air intake method, thereby increasing the overall cooling capacity and improving stability and reliability.

[0017] Optionally, the housing is provided with outdoor air inlets on both opposite sides in the left-right direction;

[0018] The rear end of the inner air duct cover has two outer sides forming air guide surfaces along the left and right directions. Each air guide surface is arranged adjacent to the outdoor air inlet, and the two air guide surfaces are arranged to gradually approach each other in the direction towards the second fan.

[0019] Optionally, the indoor air inlet is located in front of the indoor air outlet;

[0020] The inner air duct cover is adjacent to the corresponding wall of the housing along one side wall in the left and right direction, so that an installation space is reserved between the other side wall and the corresponding wall of the housing.

[0021] The air conditioner also includes a compressor and an electrical control box, both of which are located within the installation space.

[0022] Optionally, the front end of the inner air duct cover has two opposite outer surfaces forming guide slopes, and the two guide slopes are arranged to gradually approach each other in the forward direction.

[0023] Optionally, the housing is provided with outdoor air inlets on both opposite sides in the left-right direction;

[0024] The outdoor air outlet is located on the rear side of the housing.

[0025] Optionally, the housing is provided with an air inlet grille on one side along the left-right direction to form the outdoor air inlet; and / or,

[0026] The air conditioner also includes an indoor heat exchanger and an outdoor heat exchanger. The outdoor heat exchanger is located near the outdoor air outlet, and the indoor heat exchanger is located between the indoor air inlet and the indoor air outlet.

[0027] Optionally, the housing includes a top shell and a bottom shell that are snapped together in a vertical direction, wherein:

[0028] The top shell and the bottom shell are each provided with an air inlet grille on opposite sides in the left-right direction, and the air inlet grilles on the same side together form an outdoor air inlet; and / or,

[0050] This invention provides an air conditioner and vehicle with a more compact layout, which increases air intake volume. Figures 1 to 7 An embodiment of the air conditioner provided by the present invention.

[0051] Please refer to Figures 1 to 3 The air conditioner 100 includes a housing 1, a first fan 2, and a second fan 3. The housing 1 has an indoor air inlet 11a, an indoor air outlet 11b, an outdoor air inlet 12a, and an outdoor air outlet 12b. An indoor air duct 11 connecting the indoor air inlet 11a and the indoor air outlet 11b, and an outdoor air duct 12 connecting the outdoor air inlet 12a and the outdoor air outlet 12b are formed inside the housing 1. The indoor air duct 11 and the outdoor air duct 12 are spaced apart in the front-to-back direction. The indoor air inlet 11a and the indoor air outlet 11b are located at the lower part of the housing 1 and are staggered in the front-to-back direction so that the indoor air duct 11 extends in the front-to-back direction and bends upward. The outdoor air inlet 12a is located on the side of the housing 1. The first fan 2 is located inside the indoor air duct 11, and the second fan 3 is located inside the outdoor air duct 12.

[0052] In the technical solution of the present invention, the indoor air duct 11 and the outdoor air duct 12 are arranged in the front-to-back direction, which ensures that the overall space layout is compact. Due to the arrangement of the indoor air inlet 11a and the indoor air outlet 11b, the indoor air duct 11 extends in the front-to-back direction and bends upward, that is, it is inverted U-shaped. The first fan 2 realizes the indoor air intake and exhaust circulation. The outdoor air duct 12 takes in air from the side of the housing 1 and sends air towards the rear of the whole unit. Thus, the inverted U-shaped indoor air duct 11 and the outdoor air duct 12 that sends air to the rear are combined. The structure is compact, which facilitates the miniaturization design of the whole unit and reduces driving resistance. Compared with the existing air conditioner layout, it can provide a larger air volume in the same space.

[0053] It should be noted that the front-back, left-right, and up-down directions of this invention are all relative directions. The front-back direction is the length direction of the housing 1, the left-right direction is the width direction of the housing 1, and the up-down direction is the height direction of the housing 1. In this invention, the length direction of the housing 1 is consistent with the length direction of the vehicle, and the front side is the direction of the vehicle's front end.

[0054] It is understandable that the extension directions of the indoor air duct 11 and the outdoor air duct 12 are affected by the orientation of the first fan 2 and the second fan 3. This invention allows the indoor air duct 11 and the outdoor air duct 12 to be arranged in a straight line. To make the internal layout of the housing 1 more compact, in this embodiment, the first fan 2 is a cross-flow fan with its rotation axis extending in the left-right direction, and the second fan 3 is an axial flow fan with its rotation axis extending in the front-back direction. That is, they are vertically distributed, and the indoor air inlet 11a can coincide with the orientation of the outdoor air inlet 12a, resulting in a more compact layout.

[0055] Furthermore, the air conditioner 100 includes an inner duct cover 4 disposed within the housing 1 and forming the upper sidewall of the indoor air duct 11. The front end of the inner duct cover 4 is adjacent to the front inner wall of the housing 1, and the rear end of the inner duct cover 4, together with the housing 1, defines the outdoor air duct 12, so that the rear end of the inner duct cover 4 forms the front sidewall of the outdoor air duct 12. That is, the indoor air duct 11 is entirely disposed on the front side of the housing 1, while the space reserved at the rear of the inner duct cover 4 forms the outdoor air duct 12. The indoor air duct 11 adopts a layout that is offset to one side inside the whole unit, so that within the same size space, the surrounding space for the internal compressor layout is larger, improving the compatibility of replacing different compressors for different cooling capacity requirements during the compressor design process.

[0056] Furthermore, a surrounding plate 17 protrudes upward from the bottom wall of the housing 1. The surrounding plate 17 is fastened to the inner air duct cover 4 to jointly enclose and form the indoor air duct 11. The shape of the surrounding plate 17 is adapted to fit the inner air duct cover 4.

[0057] The present invention does not limit the formation method of outdoor air intake, and the air intake opening can be designed separately. Considering the impurities and rainwater that may accompany the air intake, in one embodiment, the housing 1 is provided with an air intake grille 15 on one side along the left and right direction to form an outdoor air intake 12a. The air intake grille 15 can form multiple holes, which not only increases the overall size of the outdoor air intake 12a, but also plays a protective role.

[0058] Furthermore, the air conditioner 100 also includes an indoor heat exchanger 8 and an outdoor heat exchanger 7. The outdoor heat exchanger 7 is located on the side of the second fan 3 away from the first fan 2 and close to the outdoor air outlet 12b. The indoor heat exchanger 8 is located between the indoor air inlet 11a and the indoor air outlet 11b. The outdoor heat exchanger 7 is placed at the end of the outdoor air duct 12 to allow the incoming outdoor air to mix in the outdoor air duct 12 and then pass through the outdoor heat exchanger 7 with a larger air volume, thereby improving heat exchange efficiency. The location of the indoor heat exchanger 8 is affected by the design orientation of the indoor air outlet 11b and the indoor air inlet 11a. It should be noted that the outdoor heat exchanger 7 is a condenser, and the indoor heat exchanger 8 is an evaporator.

[0059] It should be noted that the two related technical features mentioned above, the air inlet grille 15 and the heat exchanger, can be set simultaneously or one of them can be set separately. In this embodiment, they are set simultaneously.

[0060] Please refer to Figures 2 to 3 In the first embodiment, the indoor air outlet 11b is located in front of the indoor air inlet 11a. Installation space is reserved between the inner duct cover 4 and the housing 1 at both ends along the left and right directions. The air conditioner 100 also includes a compressor 5 and an electrical control box 6, which are respectively located in the installation spaces on the left and right sides of the inner duct cover 4. That is, the airflow in the indoor duct 11 is transmitted from back to front. The inner duct cover 4 is positioned in the middle and forward relative to the housing 1. At this time, installation space is reserved on each side of the inner duct cover 4 along the left and right directions. Therefore, the electrical control box 6 and the compressor 5 are respectively located on opposite sides of the inner duct cover 4 along the left and right directions. When the outdoor air inlet 12a is opened on opposite sides of the housing 1 along the left and right directions, the compressor 5 and the electrical control box 6 can both be installed in the airflow path of the outdoor duct 12, so that they can dissipate heat when outdoor air is introduced. At this time, a piping system can be installed inside the outdoor duct 12 on the side close to the compressor 5. Preferably, both the indoor air inlet 11a and the indoor air outlet 11b are located on the central axis of the housing 1 along the front-to-back direction, at which point the inner air duct cover 4 is centered.

[0061] Based on the above embodiment, the housing 1 has outdoor air inlets 12a on both opposite sides in the left-right direction. The rear end of the inner duct cover 4 has two outer sides in the left-right direction forming air guide surfaces 41. Each air guide surface 41 is positioned adjacent to the outdoor air inlet 12a, and the two air guide surfaces 41 gradually approach each other in the direction towards the second fan 2. The air guide surfaces 41 provide guidance for the air intake on both sides of the housing 1, allowing outdoor air to enter the outdoor duct 12 more smoothly. Simultaneously, the air guide surfaces 41 also, to a certain extent, enlarge the size of the outdoor duct 12 corresponding to the outdoor air inlet 12a. That is, when air enters through the two outdoor air inlets 12a, the corresponding reserved space in the housing 1 is larger, thereby increasing the air intake volume, which flows in along the air guide surfaces 41.

[0062] Furthermore, in this embodiment, the indoor heat exchanger 8 is located behind the first fan 2. That is, the indoor air is first attracted by the first fan 2 and comes into contact with the indoor heat exchanger 8 for heat exchange before entering the indoor space along the indoor air duct 11. The outdoor heat exchanger 7 is located behind the second fan 3, so that the air introduced from all directions by the outdoor air duct 12 is mixed in the duct and then discharged after heat exchange through the outdoor heat exchanger 7.

[0063] Please refer to Figures 4 to 5 In the second embodiment, the indoor air outlet 11b is located in front of the indoor air inlet 11a; the inner duct cover 4 is adjacent to the corresponding wall of the housing 1 along one side wall in the left and right direction, so that an installation space is reserved between the other side wall and the corresponding wall of the housing 1; the air conditioner 100 also includes a compressor 5 and an electrical control box 6, both of which are located within the installation space. At this time, the airflow direction in the indoor duct 11 is still from back to front, thus restricting the air inlet side of the indoor heat exchanger 8 and the placement of the first fan 2. The indoor air inlet 11a and the indoor air outlet 11b are both located to the side of the central axis of the housing 1 in the front and back direction, so that an installation space is reserved between the inner duct cover 4 along one side wall in the left and right direction and the inner wall of the housing 1. The motor cover 21 of the first fan 2 is also located within the reserved installation space. At this time, the installation space volume formed by the inner duct cover 4 on one side is larger, which can accommodate the electrical control box 6 and the compressor. All 5 are placed within the installation space, and the electrical control box 6 is located on the front side of the housing 1 and is arranged side by side with the inner air duct cover 4. This prevents the electrical control box 6 from obstructing the outdoor air intake when the outdoor air duct 12 takes in air from the side, making the outdoor air intake of the outdoor air duct 12 smoother. At the same time, the larger space on one side is conducive to the layout of the pipeline system, and there is enough space to install the pipeline fixing structure. It also ensures that there is more safety distance when the pipeline shakes so as not to collide with the relevant components of the indoor air duct 11, thereby improving the safety of the pipeline system and the reliability of the whole machine.

[0064] Understandably, this structural layout, which is offset to one side of the whole unit, has the advantage of facilitating the wiring of electrical control components. This is because the motor cover 21 of the first fan 2 in the indoor air duct 11 is located next to the electrical control box 6, and the compressor 5 is also located on the same side as the electrical control box 6, close to the rear of the whole unit. The second fan 3 is located on the central axis from the compressor 5 towards the middle of the whole unit. They all require the electrical control box 6 to control them. This concentration on the same side of the whole unit shortens the layout of the control circuit, simplifies the path of the control circuit in the manufacturing process, and improves the efficiency of wiring. Similarly, the cost of the electrical control box 6 is reduced because of the shorter wiring.

[0065] Based on the above embodiments, when the housing 1 is provided with outdoor air inlets 12a on both sides opposite to each other in the left and right directions, and the rear end of the inner air duct cover 4 has two opposite outer sides forming air guide surfaces 41 in the left and right directions, due to the offset setting of the inner air duct cover 4, the distance between the corresponding air guide surface 41 and the compressor 5 is increased compared with the first embodiment, which increases the outdoor air intake, alleviates the problem of the compressor 5 blocking part of the air intake, and enables the whole to achieve better air intake adjustment, which facilitates the circulation of air intake of the entire outdoor air intake system and improves the heat exchange efficiency of outdoor circulating air.

[0066] It is understood that in this embodiment, the indoor heat exchanger 8 and the outdoor heat exchanger 7 are positioned in the same way as in the first embodiment. That is, the indoor heat exchanger 8 is located behind the first fan 2. In other words, the indoor air is first attracted by the first fan 2 and comes into contact with the indoor heat exchanger 8 for heat exchange before entering the indoor space along the indoor air duct 11. The outdoor heat exchanger 7 is located behind the second fan 3, so that the air introduced from all directions by the outdoor air duct 12 is mixed in the duct and then discharged after heat exchange through the outdoor heat exchanger 7.

[0067] Please refer to Figures 6 to 7 In the third embodiment, the indoor air inlet 11a is located in front of the indoor air outlet 11b; the inner air duct cover 4 is adjacent to the wall surface corresponding to the housing 1 along one side wall in the left and right direction, so that an installation space is reserved between the other side wall and the wall surface corresponding to the housing 1; the air conditioner 100 also includes a compressor 5 and an electrical control box 6, both of which are located in the installation space. At this time, the airflow direction in the indoor air duct 11 is from front to back, and the indoor air direction is opposite to that in the second embodiment. Therefore, the air inlet side of the indoor heat exchanger 8 and the placement position of the first fan 2 are changed accordingly. The indoor air inlet 11a and the indoor air outlet 11b are both located on the side of the central axis of the shell 1 along the front-back direction, so that there is a reserved installation space between the side wall of the inner air duct cover 4 along the left and right directions and the inner wall of the shell 1. Due to the change in design orientation, the motor cover 21 of the first fan 2 is located on the other side opposite to the reserved installation space and is adjacent to the shell 1. At this time, the installation space volume formed by the inner air duct cover 4 on one side is larger, and the electrical control box 6 and the compressor 5 can be placed in the installation space. However, due to the change in the installation orientation of the first fan 2 and the inner air duct cover 4, the air guide surface 41 is not suitable for design in this embodiment due to the limitation of the internal air duct structure and the placement of the first fan 2.

[0068] It is understandable that the motor cover 21 is on the left side at this time, while the compressor 5 and the electrical control box 6 are on the right side. That is, the compressor 5 and the electrical control box 6 do not need to be separated from the motor cover 21 for installation space. However, the required size for wiring is slightly longer than that of the second embodiment.

[0069] Furthermore, due to the change in the installation orientation of the inner air duct cover 4, guide slopes are formed on the two opposite outer sides of the front end of the inner air duct cover 4, and the two guide slopes are gradually brought closer together in the forward direction. The structure at the front end can be improved to make the front end taper, which can improve the overall front shape of the machine, make the size of the front end of the machine smaller, and further reduce the overall wind resistance of the machine in terms of appearance.

[0070] Existing axial flow fans typically have top-mounted air outlets. This design makes it easy for foreign objects to enter from the top of the unit, causing blockages and dirt buildup in the air ducts. Furthermore, the lower air pressure against the wall during vehicle movement can compress the airflow from the outlet, affecting upward airflow and thus impacting the air circulation for condenser heat exchange. To address this, in one embodiment, the housing 1 has outdoor air inlets 12a on both sides facing left and right, and outdoor air outlets 12b on the rear side of the housing 1. In this configuration, external air enters from both sides of the housing 1 and flows backward, preventing airflow reversal. The increased airflow from both sides also ensures a consistent airflow direction at the inlets, resolving the issues of foreign objects easily falling into the top outlet and affecting airflow, as well as the lower air pressure against the wall during rapid vehicle movement compressing the airflow upward and causing poor heat exchange.

[0071] It is understood that the housing 1 can be a one-piece molded part or an assembly. In this embodiment, the housing 1 includes a top shell 13 and a bottom shell 14 that are interlocked vertically. Correspondingly, air inlet grilles 15 can be provided on opposite sides of the top shell 13 and the bottom shell 14 in the left-right direction. The air inlet grilles 15 on the same side together form an outdoor air inlet 12a. Alternatively, air inlet grilles 15 can be provided only on the top shell 13 or the bottom shell 14. Obviously, designing air inlet grilles 15 on both the top shell 13 and the bottom shell 14 results in a larger air intake. At the same time, a notch is provided at the rear joint of the top shell 13 and the bottom shell 14 to form an outdoor air outlet 12b. Alternatively, only a through hole can be provided on the top shell 13 or the bottom shell 14 as an outdoor air inlet 12a.

[0072] It should be noted that the above two related technical features, when the housing 1 is designed in a split manner, can be either set as one of the outdoor air inlet 12a and the outdoor air outlet 12b or set simultaneously. In this embodiment, they are set simultaneously.

[0073] Furthermore, the air conditioner 100 is installed on the vehicle roof, and the lower end of the housing 1 is designed to form a pre-reserved gap with the roof. The lower end face of the housing 1 has multiple through holes 16 connecting to the outdoor air duct 12. These through holes 16 are used to drain water from the outdoor air duct 12 or to allow air passing through the pre-reserved gap to enter the outdoor air duct 12 through the through holes 16. The through holes 16 not only have a drainage function, ensuring that water entering the unit during rainy weather can be quickly drained away through the through holes 16, but also serve as air inlets, allowing outdoor air to flow from the sides and bottom of the housing 1 into the outdoor air duct 12, increasing the air intake.

[0074] Furthermore, the diameter of each through hole 16 is not less than 20mm.

[0075] The present invention also provides a vehicle including the air conditioner 100 described above. The vehicle includes all the technical features of the air conditioner 100 described above, and therefore also has the technical effects brought about by all the technical features described above, which will not be described in detail here.

[0076] Specifically, this invention does not limit the specific type of vehicle. Taking a motorhome as an example, motorhomes require a larger air intake volume due to their structural characteristics to improve their heat exchange efficiency. In this embodiment, the air conditioner is a top-mounted mechanism, located on the top of the vehicle body, but it is not tightly fitted to the top of the vehicle body; a certain gap is reserved. The indoor air duct 11 is an inverted U-shaped cross-flow air duct, and the indoor air duct 11 is located near the rear or front of the entire unit. The indoor air outlet 11b and the indoor air inlet 11a are both opened on the bottom wall of the housing 1 and are connected to the vehicle's interior environment, enabling indoor air circulation. Meanwhile, the outdoor air duct 12 of the whole unit is an axial flow air duct system, and the axial flow air duct is arranged vertically to supply air to the rear of the whole unit. The outdoor air inlet 12a of the outdoor air duct 12 is located on both sides of the rear of the bottom shell 14 and the top shell 13 of the housing 1, and also includes a number of circular through holes 16 spaced apart at the bottom of the bottom shell 14. These through holes 6 also have the function of draining the bottom shell 14, ensuring that water entering the whole unit in rainy weather can be quickly drained away. The outdoor air outlet 12b is a square opening formed by the bottom shell 14 and the top shell 13, which are split in half vertically and face the rear of the whole unit. The indoor air duct 11 is offset inside the housing 1. This offset layout includes the motor cover 21 of the cross-flow motor, the compressor 5 and the electrical control box 6, which are concentrated in the reserved installation space. This increases the air intake area of ​​the outdoor air duct 12, improves the air intake smoothness of the outdoor air duct 12, and improves the air intake and heat exchange efficiency of the whole unit when the outdoor air duct 12 adopts an axial flow air duct system.
