Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to a hidden automotive air conditioner. Background Art

[0002] With the rise of the RV tourism culture, RVs have become the first choice for more and more people to travel. Of course, not only RVs, but also with the upgrading of related technologies and cost reduction in the automotive manufacturing industry, vehicles are endowed with more functions in addition to transportation, such as temporary duty stations, blood donation stations, temporary rescue stations, etc., most of which are converted from vehicles. These vehicles, different from conventional cars, need to ensure the normal operation of some functions on the vehicle after parking, such as air conditioners.

[0003] Automotive air conditioners usually include an indoor unit and an outdoor unit, where the indoor unit is installed inside the vehicle compartment and the outdoor unit is generally placed on the roof. For example, the patent with the authorization announcement number CN219903980U discloses a split top-mounted RV air conditioning system, including a top-mounted indoor unit group and an independent outdoor unit group; the top-mounted indoor unit group includes a panel assembly and an evaporation assembly installed on the roof; the independent outdoor unit group includes a condensation assembly; the top-mounted indoor unit group is installed at a first position on the roof of the RV, and the independent outdoor unit group is installed at a second position on the RV, and the second position includes other positions on the roof different from the first position, the body of the RV or the bottom of the RV.

[0004] As the uses of vehicles become more and more extensive, especially for RVs, when traveling to different regions, they may encounter strong winds, heavy rains, heat, cold and other climates. Therefore, the external outdoor unit has limitations in terms of safety and environmental tolerance. Technicians strive to install both the indoor and outdoor units inside the vehicle compartment of the RV. For the limited space inside the vehicle compartment, how to design the structure of the RV air conditioner to have both performance and minimize the occupied space has become a new trend in the development of RV air conditioners.

[0033] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0034] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0036] Refer to Figure 1 and Figure 2 , the present utility model discloses a hidden automotive air conditioner.

[0037] A hidden automotive air conditioner includes a housing 1 and a condensation system and an evaporation system both disposed within the housing 1. A first cavity 3 and a second cavity 2 that are isolated from each other are provided within the housing 1, and the condensation system and the evaporation system are respectively disposed within the first cavity 3 and the second cavity 2.

[0038] A first air inlet 33 and a first air outlet 34 are connected to the first cavity 3, and a second air inlet 23 and a second air outlet 24 are provided on the second cavity 2. The medium gas enters the first cavity 3 from the first air inlet 33, and after heat exchange through the condensation system, it is then discharged via the first air outlet 34. The temperature-regulating gas enters the second cavity 2 from the second air inlet 23, and after heat exchange through the evaporation system, it is then blown out via the second air outlet 24, and the second air outlet 24 faces the area to be temperature-regulated.

[0039] The so-called temperature-regulating gas refers to the gas used to regulate the temperature in the environment to be temperature-regulated (refrigeration or heating area). The gas in the area to be temperature-regulated enters the second cavity through the second air inlet, and heat exchange occurs in the second cavity. The temperature of the gas rises or falls, and then it is blown out through the second air outlet into the area to be temperature-regulated to heat or cool the area to be temperature-regulated.

[0040] In contrast, the so-called medium gas refers to the gas from an area outside the environment to be temperature-regulated (refrigeration or heating area). This gas enters the first cavity and exchanges heat with the condensation system. The condensation system absorbs heat from these gases and releases heat to these gases. After heat exchange with the condensation system, these gases are finally discharged from the first air outlet to an area outside the environment to be temperature-regulated (refrigeration or heating area). This gas does not enter the environment to be temperature-regulated and does not directly raise or lower the temperature of the environment to be temperature-regulated. Therefore, these gases are called medium gases here.

[0041] Based on the above technical solution, both the evaporation system and the condensation system are arranged inside the housing. In this way, when installing this automotive air conditioner, the entire automotive air conditioner can be installed inside the vehicle, reducing the probability and degree of influence of the automotive air conditioner by the external environment, significantly reducing the failure rate of the automotive air conditioner, and extending the service life of the automotive air conditioner. In addition, installing the entire automotive air conditioner inside the vehicle enables this automotive air conditioner to operate normally in a relatively harsh environment.

[0042] Both the evaporation system and the condensation system are arranged inside the housing, and at the same time, the first air inlet, the first air outlet, the second air inlet, and the second air outlet are respectively provided. The automotive air conditioner of this solution can not only be installed inside the vehicle, but can also be further hidden inside or at the bottom or top of furniture devices such as cabinets, making the most of the interior space of the vehicle. In addition, this automotive air conditioner can be integrated with the interior decoration of the vehicle, not only improving the aesthetics, but also avoiding the visual interference caused by the obtrusive appearance to the passengers and drivers.

[0043] Based on the above technical solution, the evaporation system and the condensation system are respectively arranged in the mutually isolated first cavity and second cavity, reasonably dividing the internal space of the housing. The first cavity and the second cavity are mutually isolated, enabling the evaporation system and the condensation system to operate normally, and enabling the air conditioner equipped with both the evaporation system and the condensation system to operate normally.

[0044] In the technical solution of the utility model, the condensation system includes a condenser 31 and a condensation fan 32. The condensation fan 32 and the first air inlet 33 are respectively located on both sides of the condenser 31, so that the medium gas entering the first cavity through the first air inlet can directly pass through the condenser and be sucked by the condensation fan, ensuring that the medium gas contacts the condenser, achieving sufficient heat exchange with the condenser, increasing the contact amount between the condenser and the medium gas, making the medium gas contact the condenser evenly, ensuring the heat exchange efficiency, and ensuring the normal and efficient operation of the automobile air conditioner.

[0045] The first air outlet 34 is arranged toward the air outlet of the condensing fan 32, so that the medium gas blown out by the condensing fan can directly enter and be blown out from the first air outlet, thereby preventing the gas blown out by the air outlet of the condensing fan from staying in the first cavity or entering other areas in the automobile air conditioner, thereby affecting the normal operation of the automobile air conditioner.

[0046] The condensing fan 32 is working, and the medium gas enters the first cavity 3 from the first air inlet 33 and passes through the condenser 31, and is finally blown out by the condensing fan 32 and discharged from the first air outlet 34. The condensing fan 32 is working, and the medium gas is sucked in from the first air inlet 33. After the medium gas enters the first cavity, it will contact the condenser, exchange heat with the condenser, and then be blown out through the air outlet of the condensing fan. The medium gas blown out by the condensing fan is directly discharged from the first air outlet and discharged to the area outside the temperature-adjusting environment (cooling or heating area).

[0047] In the technical solution of the present utility model, the first air inlet 33 is arranged at the bottom, top or side of the shell 1; the first air outlet 34 is arranged at the bottom, top or side of the shell 1, and the first air outlet 34 and the first air inlet 33 are arranged with a position height difference in the height direction of the shell 1.

[0048] Based on the above technical solution, the first air outlet 34 and the first air inlet 33 are arranged with a position height difference in the height direction of the shell 1 to avoid interference between air inlet and air outlet on the condensation side, and to avoid the second air flow inlet from inhaling a large amount of gas discharged from the second air flow outlet as much as possible, thereby ensuring the heat exchange efficiency of the condenser.

[0049] Based on the above technical solution, according to the installation position of this automotive air conditioner in the vehicle, the first air inlet can be installed at the bottom, top or side of the housing 1, and the first air outlet 34 can be set at the bottom, bottom or side of the housing 1. To facilitate the medium gas exchange between the first air outlet 34 and the first air inlet 33 and the outside, air guide ports can be provided at positions on the vehicle near the first air outlet 34 and the first air inlet 33, which are respectively communicated with the first air outlet 34 and the first air inlet 33. The air guide ports can be provided on the bottom surface, top surface or side surface of the vehicle. The air guide ports can be directly communicated with the first air outlet 34 and the first air inlet 33, or can be communicated with the first air outlet 34 and the first air inlet 33 through air guide pipes. When choosing the installation positions of the first air outlet 34 and the first air inlet 33, the principle followed is to be as convenient as possible for the installation of this automotive air conditioner inside the vehicle, to facilitate the hiding of the automotive air conditioner inside the vehicle, to occupy less interior space of the vehicle, and to integrate and combine with other furnishings inside the vehicle, so as to achieve the effects and purposes of practicality and aesthetics.

[0050] In the technical solution of this utility model, the evaporation system includes an evaporator 21 and an evaporation fan 22. The evaporation fan 22 and the second air inlet 23 are respectively located on both sides of the evaporator 21, which is convenient for the temperature-adjusting gas entering the second cavity through the second air inlet to directly pass through the evaporator and be sucked by the evaporation fan, ensuring that the temperature-adjusting gas contacts the evaporator, realizing sufficient heat exchange with the evaporator, increasing the contact amount between the temperature-adjusting gas and the evaporator, making the temperature-adjusting gas contact the evaporator evenly, ensuring the heat exchange efficiency, and enabling rapid and efficient temperature adjustment of the area to be temperature-adjusted.

[0051] To further improve the temperature adjustment of the area to be temperature-adjusted and accelerate the temperature adjustment effect of the area to be temperature-adjusted, the second air inlet 23 is oriented towards the area to be temperature-adjusted. In this way, the gas or air in the area to be temperature-adjusted enters the second cavity, is temperature-adjusted by the evaporation system, and then is blown out to the area to be temperature-adjusted by the second air outlet, realizing the temperature adjustment of the area to be temperature-adjusted. The second air inlet 23 being oriented towards the area to be temperature-adjusted enables the temperature-adjusting gas to enter the second cavity repeatedly or multiple times, realizing multiple temperature adjustments, and the temperature adjustment effects accumulate, at least partially accumulate, which can improve the temperature adjustment effect in the area to be temperature-adjusted.

[0052] The second air outlet 24 is communicated with the air outlet 221 of the evaporation fan, so that the temperature-adjusting gas blown out by the evaporation fan can directly enter and be blown out by the second air outlet, avoiding the temperature-adjusting gas blown out by the air outlet of the evaporation fan staying in the second cavity or entering other areas inside the automotive air conditioner, which may affect the normal operation of the automotive air conditioner and the temperature adjustment of the area to be temperature-adjusted.

[0053] The evaporation fan 22 operates, and the temperature-regulating gas enters the second cavity 2 through the second air inlet 23, passes through the evaporator 21, and is finally blown out by the evaporation fan 22 and discharged through the second air outlet 24. When the evaporation fan operates, the temperature-regulating gas is inhaled from the second air inlet. After the temperature-regulating gas enters the second cavity, it will come into contact with the evaporator and exchange heat with the evaporator. Then it is blown out through the air outlet of the evaporation fan. The temperature-regulating gas blown out by the evaporation fan is discharged through the second air outlet and discharged into the environment to be temperature-regulated (refrigeration or heating area).

[0054] Generally, the evaporator and the condenser are arranged in regular shapes, which is convenient for installation and layout in the first cavity and the second cavity, and is conducive to the concealed installation of this automotive air conditioner.

[0055] Furthermore, in the existing market, most evaporators and condensers are in the shape of a cuboid. If the evaporator and the condenser are in the shape of a cuboid, when the condenser and the evaporator are respectively installed in the first cavity and the second cavity, it is ensured that the condenser and the evaporator are arranged in parallel. This is conducive to reducing the overall volume of the housing and is conducive to the concealed installation of this automotive air conditioner.

[0056] In the technical solution of the present utility model, the second air inlet 23 is arranged at the bottom, top or side of the housing 1. The second air outlet 24 is arranged at the bottom, bottom or side of the housing 1.

[0057] The second air inlet 23 absorbs gas from the area to be temperature-regulated, and the second air outlet 24 blows air into the area to be temperature-regulated. If this automotive air conditioner is installed in a vehicle, the area to be temperature-regulated is the internal space of the vehicle. Therefore, both the second air inlet 23 and the second air inlet 23 are facing the internal space of the vehicle.

[0058] If this automotive air conditioner is installed on the vehicle floor, the second air inlet 23 and the second air inlet 23 can be arranged on the side or top surface of the housing, and it is ensured that there is no obstruction in front of the second air inlet 23 and the second air inlet 23 after installation. If this automotive air conditioner is installed on the vehicle ceiling, the second air inlet 23 and the second air inlet 23 can be arranged on the side or bottom surface of the housing. Similarly, it is ensured that there is no obstruction in front of the second air inlet 23 and the second air inlet 23 after installation.

[0059] The second air inlet 23 and the second air inlet 23 can be installed on the same surface or different surfaces of the housing. Generally, the second air inlet 23 and the second air inlet 23 are installed on the same surface of the housing. This is conducive to the utilization of the external space of this surface of the housing, and furniture etc. can be placed outside other surfaces of the housing, which will not affect the smooth intake and exhaust of the second air inlet 23 and the second air inlet 23.

[0060] Of course, in order to quickly adjust the temperature of the area to be temperature-adjusted and ensure that the temperatures at various positions within the area to be temperature-adjusted are balanced, the second air outlet 24 may also include a number of independent small air outlets, and each small air outlet is arranged on the same surface or different surfaces of the housing 1. If each small air outlet is arranged on two or more different surfaces, it can realize air supply to different directions of the area to be temperature-adjusted, quickly adjust the temperature of the area to be temperature-adjusted, and ensure that the temperatures at various positions within the area to be temperature-adjusted are balanced.

[0061] Preferably, this automotive air conditioner is installed close to the vehicle ground. The first air inlet is arranged on the bottom surface of the housing, the first air outlet is also arranged on the bottom surface of the housing, and the position of the first air inlet is lower than that of the first air outlet. In addition, the second air inlet is arranged on one side surface of the housing, the second air outlet and the second air inlet are arranged on the same side surface, and the second air inlet is located below the second air outlet. Of course, some small air outlets of the second air outlet may also be located on the top surface of the housing. This places the positions of each air inlet below the position of the air outlet, which is more in line with the principle that hot air rises in aerodynamics.

[0062] In this technical solution, a third cavity 4 is further arranged in the housing 1. The third cavity 4 is isolated from both the first cavity 3 and the second cavity 2. The third cavity 4 communicates with the second air outlet 24 and the air outlet 221 of the evaporation fan. Each small air outlet is arranged on the third cavity 4. The temperature-adjusted air flow blown out from the air outlet 221 of the evaporation fan enters the third cavity. The third cavity can temporarily store the temperature-adjusted air flow, and then the temperature-adjusted air flow is blown out from the second air outlet 24. The air pressure in the third cavity is relatively high, and the temperature-adjusted air flow blown out from the second air outlet 24 can be transported to a farther distance.

[0063] In this technical solution, the evaporation fan is a centrifugal fan, including but not limited to a forward double-sided centrifugal fan and a forward centrifugal fan. When the evaporation fan is a forward double-sided centrifugal fan, as Figure 3 shown, the forward double-sided centrifugal fan is installed in the second cavity, and the air outlet of the forward double-sided centrifugal fan communicates with the third cavity. When the evaporation fan is a forward centrifugal fan, as Figure 4 shown, the forward centrifugal fan is installed in the second cavity, but is isolated from the evaporator by a partition, so that the air inlet of the forward centrifugal fan can suck the temperature-adjusted air flow that has exchanged heat through the evaporator, and the air flow blown out through the air outlet of the forward centrifugal fan directly enters the third cavity and then is blown out from the second air outlet, or is directly blown out from the second air outlet, avoiding the interference between the air flow blown out from the air outlet of the forward centrifugal fan and the temperature-adjusted air flow in the second cavity.

[0064] If the evaporation fan is a forward double-sided centrifugal fan, the axial length of a general forward double-sided centrifugal fan is greater than its diameter. Therefore, in order to reduce the volume of the housing, when installing the forward double-sided centrifugal fan, ensure that the axis of the forward double-sided centrifugal fan is parallel to the evaporator. If the evaporation fan is a forward centrifugal fan, due to its structure and working characteristics, when installing the forward centrifugal fan, ensure that the axis of the forward centrifugal fan is perpendicular to the evaporator.

[0065] In this technical solution, a fourth cavity 5 is further provided in the housing 1. The fourth cavity 5 is isolated from both the second cavity 2 and the third cavity 4. An enthalpy-increasing system 50 is provided in the fourth cavity 5, and the enthalpy-increasing system 50 is communicated with both the condensation system and the evaporation system. By setting the enthalpy-increasing system, the purpose of improving the heating capacity under low-temperature environments can be achieved.

[0066] In this technical solution, the enthalpy-increasing system 50 is a jet enthalpy-increasing system, including an enthalpy-increasing compressor 51, a four-way valve 52, a throttling component, and a flash evaporator 53. The enthalpy-increasing compressor 51, the four-way valve 52, the throttling component, the flash evaporator 53, the condenser 31, and the evaporator 21 are communicated through pipelines. The jet enthalpy-increasing system adopts an enthalpy-increasing compressor and the two-stage throttling and intermediate jetting technology, and uses a flash evaporator for gas-liquid separation to achieve the enthalpy-increasing effect. By mixing and cooling while compressing at medium and low pressures and then normally compressing at high pressures, the compressor displacement is increased, and the purpose of improving the heating capacity under low-temperature environments can be achieved.

[0067] Based on the above solution, the jet enthalpy-increasing system is located inside the housing, thus avoiding interference with the external environment, being more conducive to installation in a limited narrow space, and improving the compactness of the space. Preferably, an electromagnetic valve 54 and an electronic expansion valve 55 are further provided on the pipeline of the enthalpy-increasing system to regulate the flow of the refrigerant.

[0068] Preferably, the jet enthalpy-increasing system is arranged in the middle of the condensation system and the evaporation system, which is conducive to the connection between the jet enthalpy-increasing system and the condensation system and the evaporation system, is beneficial to the pipeline layout, makes the entire air-conditioning system structure more compact, occupies less space inside the vehicle, and improves the space utilization rate inside the RV.

[0069] In this technical solution, in order to reduce the volume of the automotive air conditioner, the fourth cavity is communicated with the first cavity, and the first air inlet is arranged in the fourth cavity, so that the medium air flow entering from the first air inlet can fully contact the condenser, and at the same time, the space and volume of the first cavity are reduced. Further, as Figure 2 shown, by arranging the jet enthalpy-increasing system and the first air inlet side by side in the width direction, the space utilization rate is further increased, making the entire RV air conditioner more compact and more conducive to realizing a concealed installation.

[0070] In this technical solution, to facilitate the maintenance of the components inside the housing, the housing 1 includes an upper housing 11 and a lower housing 12 which are fixedly connected to each other. When it is necessary to maintain the inside of the air conditioner, the upper housing 11 or the lower housing 12 can be disassembled, and the operation is convenient.

[0071] To improve the adaptability of this automotive air conditioner, each surface of the upper housing 11 and the lower housing 12 is set as a flat surface. The condensation system, the evaporation system, and the enhanced enthalpy system 50 are all fixedly installed on the upper housing 11 or the lower housing 12; the upper housing 11 or the lower housing 12 is fixedly installed on the vehicle.

[0072] When the automotive air conditioner is fixedly installed on the vehicle through the upper housing, the upper housing is fixed to the vehicle. At this time, the condensation system, the evaporation system, the enhanced enthalpy system 50, etc. are all fixedly installed on the upper housing, and the lower housing is detachably and fixedly connected to the upper housing. If the air conditioner needs to be maintained, the lower housing can be disassembled. When the automotive air conditioner is fixedly installed on the vehicle through the lower housing, the lower housing is fixed to the vehicle. At this time, the condensation system, the evaporation system, the enhanced enthalpy system 50, etc. are all fixedly installed on the lower housing, and the upper housing is detachably and fixedly connected to the lower housing. If the air conditioner needs to be maintained, the upper housing can be disassembled.

[0073] To facilitate the installation of the air conditioner, make the air conditioner installation stable, and also facilitate the hidden installation of the air conditioner, generally, the top surface of the upper housing and the bottom surface of the lower housing are both set as flat surfaces or most areas are set as flat surfaces. When the air conditioner is installed on the vehicle, it can make good contact with the installation surface, which is convenient for the installation surface of the air conditioner to closely adhere to the installation position and be placed stably in the installation position.

[0074] The technical means disclosed in the solution of this utility model are not limited to the technical means disclosed in the above embodiments, but also include the technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of this utility model.
