Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] Air conditioners have become an indispensable device in modern life. Their core function is to regulate the temperature of indoor air through a heat pump system. A traditional air conditioner's indoor unit typically includes a casing, an evaporator housed within the casing, and a fan assembly that drives the airflow. Its general operating procedure is as follows: the fan draws indoor air in through the air inlet, it flows through the evaporator for heat exchange, cooling or heating it before it is blown out through the air outlet, thus circulating to regulate room temperature.

[0003] Currently, most floor-standing and wall-mounted air conditioner indoor units on the market use a single evaporator structure. This evaporator is typically a flat or L-shaped layout, with airflow entering from one side or the front, passing through the evaporator, and then being exhausted by a fan from the front or top. While this traditional structure has matured over a long period, its inherent drawbacks are becoming increasingly apparent, mainly in the following aspects: Limited heat exchange efficiency: The effective heat exchange area of ​​a single evaporator is fixed, becoming a major bottleneck in improving the air conditioner's energy efficiency ratio (APF). Within a limited space, it is difficult to significantly increase the heat exchange area to further improve heat exchange efficiency, leading to the need for higher-power fans or compressors to achieve the same cooling / heating capacity, which is detrimental to energy conservation. Uneven airflow and poor comfort: The single-side air intake method easily leads to uneven airflow distribution, with the evaporator fins on the side furthest from the air inlet not being fully utilized, forming a "heat exchange dead zone." Simultaneously, the cooled air is concentrated and blown out from the outlet, easily creating a strong "cold wind" sensation, which can cause discomfort when blown directly onto the body, affecting user comfort. Therefore, it is necessary to innovate the mechanical structure of existing air conditioning indoor units and design a new structure that can effectively increase the heat exchange area, optimize the airflow path, fundamentally improve heat exchange efficiency, and improve air supply comfort within a limited space. Utility Model Content

[0004] Therefore, it is necessary to provide an air conditioner that addresses the technical problems of insufficient heat exchange efficiency and poor comfort in existing air conditioners.

[0005] An air conditioner includes a housing, a heat pump assembly, and a fan assembly. The heat pump assembly and the fan assembly are both installed inside the housing. The heat pump assembly is located at the bottom of the housing, and the fan assembly is located at the top of the housing. The output end of the fan assembly is connected to the outside of the housing through the side wall of the housing.

[0006] The heat pump assembly includes a first evaporator, a first circulation pipe, a second evaporator, and a second circulation pipe. With the fan assembly and heat pump assembly arranged vertically, the first and second evaporators are arranged horizontally in the middle of the housing, and the first and second evaporators are arranged in a V-shape to form a mirror-symmetrical structure. The fan assembly is located on the open side of the V-shaped structure of the first and second evaporators. One end of the first circulation pipe is connected to the first evaporator, and the other end of the first circulation pipe extends to the outside of the housing to cooperate with external heat pump components to form a complete heat pump structure. One end of the second circulation pipe is connected to the second evaporator, and the other end of the second circulation pipe extends to the outside of the housing to cooperate with external heat pump components to form a complete heat pump structure.

[0007] The housing is provided with a first air inlet and a second air inlet on opposite sides of the first evaporator and the second evaporator, respectively. The first air inlet connects the side of the first evaporator opposite to the second evaporator to the outside of the housing, and the second air inlet connects the side of the second evaporator opposite to the first evaporator to the outside of the housing.

[0008] In one embodiment, the aforementioned fan assembly includes a plurality of fan units, which are disposed on top of the first evaporator and the second evaporator, with the output end of each fan unit facing the top side.

[0009] In one embodiment, an air outlet is provided on one side wall of the top of the aforementioned housing.

[0010] In one embodiment, the aforementioned fan assembly includes two fan units, which are respectively disposed on the top sides of the first evaporator and the second evaporator.

[0011] In one embodiment, each of the above-mentioned fan units includes two fans, which are arranged along the width direction of the corresponding first evaporator and second evaporator.

[0012] In one embodiment, the aforementioned housing is provided with a bracket for each fan, the bracket being disposed on the bottom side of the corresponding fan and connected to the side wall of the housing; the corresponding fan is installed onto the bracket.

[0013] In one embodiment, the aforementioned housing is provided with a sealing plate for each fan unit. The sealing plate is located on the top side of the corresponding fan unit and connected to the side wall of the housing. The two fan output ends of the corresponding fan unit are connected to the air outlet on the top side wall of the housing through the sealing plate.

[0014] In one embodiment, each of the aforementioned sealing plates is provided with two ventilation openings, and the output ends of the corresponding two fans are respectively matched with the two ventilation openings.

[0015] In one embodiment, the aforementioned housing is provided with a first support plate corresponding to the first evaporator, the first support plate is disposed on the bottom side of the first evaporator and connected to the housing; the first evaporator is installed onto the first support plate.

[0016] In one embodiment, the aforementioned housing is provided with a second support plate corresponding to the second evaporator, the second support plate is disposed on the bottom side of the second evaporator and connected to the housing; the second evaporator is installed onto the second support plate.

[0017] The aforementioned air conditioner, through its V-shaped arrangement of the first and second evaporators, maximizes the effective heat exchange area within a limited cabinet space. Simultaneously, the dual-side air intake design draws air in from both sides, flowing across the entire surface of each evaporator. This avoids the problem of insufficient utilization of the evaporator fins on the side furthest from the air inlet, as is common with traditional single-side air intake. Furthermore, the short and uniform airflow path results in relatively low wind resistance, significantly improving heat exchange efficiency. The two airflows, cooled by different evaporators, converge and mix in the central area of ​​the V-shaped structure before being blown out by the top fan assembly. This helps eliminate localized cold spots, resulting in a more uniform outlet air temperature. Additionally, due to the large heat exchange area, a lower air velocity is required to achieve the same cooling capacity, thus providing gentler airflow. The first and second circulation pipes extend independently to the outside of the cabinet, connecting to external heat pump components (compressor, condenser, and throttling device), ensuring system scalability.

[0025] Please see Figures 1 to 4This utility model discloses an air conditioner 1, which includes a housing 10, a heat pump assembly 20, and a fan assembly 30. The heat pump assembly 20 and the fan assembly 30 are both installed inside the housing 10. The heat pump assembly 20 is located at the bottom of the housing 10, and the fan assembly 30 is located at the top of the housing 10. The output end of the fan assembly 30 is connected to the outside of the housing 10 through the side wall of the housing 10. Thus, the fan assembly 30 can provide power for the airflow inside the housing 10, driving the airflow to be cooled to a preset temperature through the evaporator of the heat pump assembly 20, and then output to the outside of the housing 10 through the top side wall of the housing 10, thereby realizing the air conditioning function. Specifically, the heat pump assembly 20 includes a first evaporator 21, a first circulation pipe 22, a second evaporator 23, and a second circulation pipe 24. With the fan assembly 30 and the heat pump assembly 20 arranged vertically, the first evaporator 21 and the second evaporator 23 are arranged horizontally in the middle of the housing 10, and the first evaporator 21 and the second evaporator 23 are arranged in a V-shape to form a mirror-symmetrical structure. The fan assembly 30 is located on the open side of the V-shaped structure of the first evaporator 21 and the second evaporator 23. One end of the first circulation pipe 22 is connected to the first evaporator 21, and the other end of the first circulation pipe 22 extends to the outside of the housing 10 to cooperate with external heat pump components to form a complete heat pump structure. One end of the second circulation pipe 24 is connected to the second evaporator 23, and the second circulation pipe 24... The other end extends to the outside of the housing 10 to form a complete heat pump structure with the external heat pump components. Correspondingly, the housing 10 is provided with a first air inlet a and a second air inlet b on the opposite sides of the first evaporator 21 and the second evaporator 23, respectively. The first air inlet a connects the side of the first evaporator 21 opposite to the second evaporator 23 to the outside of the housing 10, and the second air inlet b connects the side of the second evaporator 23 opposite to the first evaporator 21 to the outside of the housing 10. Thus, driven by the fan assembly 30, the airflow outside the housing 10 enters the housing 10 through the first air inlet a and the second air inlet b, and after being cooled by the first evaporator 21 and the second evaporator 23, it converges between the two and is then blown out from the top of the housing 10 by the fan assembly 30, thereby completing the air temperature regulation process.Compared to traditional air conditioning equipment, the air conditioner 1 in this solution can increase the effective heat exchange area within the limited space of the cabinet 10 by using the V-shaped arrangement of the first evaporator 21 and the second evaporator 23. At the same time, the dual-side air intake design allows airflow to be drawn in from both sides and flow over the entire surface of the two evaporators, avoiding the problem of insufficient utilization of the evaporator fins on the side far from the air inlet in traditional single-side air intake. In addition, the airflow path is short and uniform, and the wind resistance is relatively small, thus significantly improving the heat exchange efficiency. The two airflows cooled by different evaporators converge and mix in the central area of ​​the V-shaped structure, and are then blown out by the top fan assembly 30, which helps to eliminate local cold spots and make the outlet air temperature more uniform. At the same time, due to the large heat exchange area, a lower wind speed is required to achieve the same cooling capacity, thus achieving gentle air delivery. The first and second circulation pipes 24 extend independently to the outside of the cabinet 10 and connect to external heat pump components (compressor, condenser, throttling device), thus ensuring the scalability of the system.

[0026] Furthermore, the fan assembly 30 includes several fan units disposed on top of the first evaporator 21 and the second evaporator 23. The output end of each fan unit faces the top side to deliver the airflow cooled by the first evaporator 21 and the second evaporator 23 to the top of the housing 10. Correspondingly, an air outlet c is provided on one side wall of the top of the housing 10, and the dry and cold airflow output by the several fan units is output to the outside of the housing 10 through the air outlet c. In one embodiment, the fan assembly 30 includes two fan units, which are respectively disposed on the top side of the first evaporator 21 and the second evaporator 23 to completely cover the open side of the V-shaped structure formed by the first evaporator 21 and the second evaporator 23.

[0027] Furthermore, in one embodiment, each fan unit includes two fans 31, which are arranged along the width direction of the corresponding first evaporator 21 and second evaporator 23 to completely cover the air outlet range of the corresponding first evaporator 21 and second evaporator 23.

[0028] Furthermore, the housing 10 is provided with a bracket 11 for each fan 31. The bracket 11 is located on the bottom side of the corresponding fan 31 and connected to the side wall of the housing 10. The corresponding fan 31 is installed on the bracket 11, so that the fans 31 can be stably mounted on the top side of the heat pump assembly 20.

[0029] Furthermore, each fan unit in the housing 10 is provided with a sealing plate 12, which is located on the top side of the corresponding fan unit and connected to the side wall of the housing 10. The output ends of the two fans 31 of the corresponding fan unit are connected to the air outlet c on the top side wall of the housing 10 through the sealing plate 12. Thus, the sealing plate 12 separates the internal area of ​​the housing 10 while realizing the directional and concentrated output of dry and cold airflow, reducing turbulence inside the housing 10. In one embodiment, each sealing plate 12 is provided with two ventilation openings d, and the output ends of the two corresponding fans 31 are respectively matched with the two ventilation openings d, thereby realizing the connection between the fans 31 and the air outlet area at the top of the housing 10.

[0030] Furthermore, the housing 10 is provided with a first support plate 13 corresponding to the first evaporator 21. The first support plate 13 is located on the bottom side of the first evaporator 21 and connected to the housing 10. The first evaporator 21 is installed on the first support plate 13, so that the first evaporator 21 can be stably installed on the bottom side of the fan assembly 30, and the first support plate 13 can separate the cooling area of ​​the first evaporator 21 from the bottom side of the housing 10.

[0031] Furthermore, the housing 10 is provided with a second support plate 14 corresponding to the second evaporator 23. The second support plate 14 is located on the bottom side of the second evaporator 23 and connected to the housing 10. The second evaporator 23 is installed on the second support plate 14, so that the second evaporator 23 can be stably installed on the bottom side of the fan assembly 30, and the second support plate 14 can separate the cooling area of ​​the second evaporator 23 from the bottom side of the housing 10.

[0032] In summary, the air conditioner disclosed in this utility model can increase the effective heat exchange area within a limited cabinet space through the V-shaped arrangement of the first and second evaporators. Simultaneously, the dual-side air intake design allows airflow to be drawn in from both sides and flow across the entire surface of the two evaporators, avoiding the problem of insufficient utilization of the evaporator fins on the side furthest from the air inlet in traditional single-side air intake designs. Furthermore, the airflow path is short and uniform, with relatively low wind resistance, thus significantly improving heat exchange efficiency. The two airflows, cooled by different evaporators, converge and mix in the central area of ​​the V-shaped structure before being blown out by the top fan assembly, helping to eliminate localized cold spots and making the outlet air temperature more uniform. Additionally, due to the large heat exchange area, a lower air velocity is required to achieve the same cooling capacity, thus achieving gentle airflow. The first and second circulation pipes extend independently to the outside of the cabinet, connecting to external heat pump components (compressor, condenser, throttling device), ensuring the system's scalability.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
