Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning, and more specifically, to an air conditioning unit. Background Technology

[0002] In existing technologies, to ensure the cooling and heating efficiency of floor-standing air conditioners, some employ top and bottom air outlets to achieve rapid cooling from the top and carpet-like distribution of warm air. However, this method uses centrifugal fans, whose inlet and outlet are angled, resulting in airflow loss. If a common cross-flow fan is used, air can only be drawn in from the rear, leading to small intake and exhaust volumes. Floor-standing air conditioners are typically used for cooling or heating in relatively large spaces, requiring higher airflow. In short, the intake and exhaust volumes of existing floor-standing air conditioners are relatively small and need further improvement. Utility Model Content

[0003] The purpose of this utility model is to provide an air conditioner cabinet unit to solve the technical problem that the air intake and air supply volume of existing air conditioner cabinet units are relatively small.

[0004] The air conditioner cabinet unit provided by this utility model includes a housing, in which a mixed-flow fan and an annular evaporator are disposed. The annular evaporator is vertically arranged, and the air inlet of the mixed-flow fan is located at the upper or lower end of the annular evaporator and communicates with the central cavity of the annular evaporator; the air outlet of the mixed-flow fan is communicated with the air outlet of the housing.

[0005] The air conditioner unit provided by this utility model can produce the following beneficial effects:

[0006] The air conditioner unit provided by this utility model adopts an annular evaporator and a mixed-flow fan. The annular evaporator can perform all-around heat exchange with the surrounding air intake, with a large heat exchange area, thereby improving heat exchange efficiency and laying a solid foundation for improving the overall cooling and heating efficiency of the unit. Furthermore, the annular evaporator has less restriction on the air intake direction, which is conducive to increasing the air intake volume. The mixed-flow fan is equipped with a high-speed motor, and a conical diffuser is formed in the center of the air duct, with a guide ring on the outer ring, thus forming an annular accelerating air outlet. A ring of ribs is also provided at the air outlet of the mixed-flow fan to achieve a spiral high-speed air outlet, resulting in a large air delivery volume. In summary, this utility model directly places the mixed-flow fan at the upper or lower end of the annular evaporator, which is beneficial for improving both the air intake volume and heat exchange efficiency, as well as the air delivery volume.

[0007] Furthermore, the mixed-flow fan has two components: an upper mixed-flow fan and a lower mixed-flow fan. The air inlet of the upper mixed-flow fan is located at the upper end of the annular evaporator and communicates with the central cavity of the annular evaporator. The air inlet of the lower mixed-flow fan is located at the lower end of the annular evaporator and communicates with the central cavity of the annular evaporator. The air outlet includes a top air outlet and a bottom air outlet. The air outlet of the upper mixed-flow fan is connected to the top air outlet, and the air outlet of the lower mixed-flow fan is connected to the bottom air outlet.

[0008] In this technical solution, after the annular evaporator exchanges heat with the incoming air, the upper mixed-flow fan can promptly deliver the heat-exchanged air upwards to the top air outlet, while the lower mixed-flow fan can promptly deliver the heat-exchanged air downwards to the bottom air outlet. Due to the principle that cold air descends and hot air rises, in cooling mode, the upper mixed-flow fan operates and delivers cold air to the top air outlet, allowing the cold air to diffuse outside the unit, effectively increasing the airflow from the top of the air conditioner unit. In heating mode, the lower mixed-flow fan operates and delivers hot air to the bottom air outlet, allowing the hot air to diffuse outside the unit, effectively increasing the airflow from the bottom of the air conditioner unit. Of course, both mixed-flow fans can operate in cooling, heating, or other modes.

[0009] Furthermore, the housing includes a main frame, a top plate, and a bottom plate. A top air outlet is formed between the main frame and the top plate, and a bottom air outlet is formed between the main frame and the bottom plate. An upper air outlet is provided at the top of the main frame, and the upper air outlet communicates with the top air outlet. A lower air outlet is provided at the bottom of the main frame, and the lower air outlet communicates with the bottom air outlet.

[0010] Furthermore, the top air outlet is positioned facing forward. In this technical solution, the air delivered upward by the upper mixing fan is blocked by the top plate and then output forward through the top air outlet.

[0011] Furthermore, the bottom air outlet is positioned facing forward. In this technical solution, the air delivered downward by the lower mixing fan is blocked by the base plate and then output forward through the bottom air outlet.

[0012] Furthermore, the air outlet also includes a main air outlet, which is located forward on the upper part of the housing and is connected to the air outlet end of the upper mixed flow fan.

[0013] Furthermore, the main air outlet is provided with an upper mounting plate, which has a hollow structure, and an air outlet plate is provided outside the upper mounting plate. With this technical solution, the hollow structure of the upper mounting plate ensures that it does not obstruct the airflow as much as possible, while also improving the structural strength of the housing at and around the main air outlet.

[0014] Furthermore, the lower part of the casing is provided with multiple air inlets along the circumference, and each of the multiple air inlets is arranged opposite to the annular evaporator. Under this technical solution, the air conditioning unit provided by this utility model has a relatively large air intake area, thereby effectively increasing the air intake volume. Combined with the annular evaporator with a large heat exchange area and the mixed flow fan with a large air supply volume, it can further ensure the cooling and heating efficiency of the whole unit.

[0015] Furthermore, the air inlet includes a front air inlet, a left rear air inlet, a right rear air inlet, and a rear air inlet.

[0016] Furthermore, the front air inlet is provided with a lower mounting plate, which has a hollow structure, and an air inlet plate is provided outside the lower mounting plate. With this technical solution, the hollow structure of the lower mounting plate ensures that it does not obstruct airflow as much as possible, while also improving the structural strength of the housing in and around the front air inlet.

[0027] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0028] This embodiment provides an air conditioner cabinet unit, such as... Figures 1 to 3 As shown, the air conditioner cabinet unit includes a housing 100, inside which a mixed-flow fan and an annular evaporator 200 are installed. The annular evaporator 200 is vertically positioned. There are two mixed-flow fans, namely an upper mixed-flow fan 310 and a lower mixed-flow fan 320. The air inlet of the upper mixed-flow fan 310 is located at the upper end of the annular evaporator 200 and communicates with the central cavity of the annular evaporator 200. The air inlet of the lower mixed-flow fan 320 is located at the lower end of the annular evaporator 200 and communicates with the central cavity of the annular evaporator 200. The air outlets of both the upper mixed-flow fan 310 and the lower mixed-flow fan 320 are connected to the air outlet of the housing 100.

[0029] It should be noted that in other embodiments of this application, the number of mixed-flow fans is not limited to two, but can be specifically set as needed. For example, there can be only one mixed-flow fan, that is, only the upper mixed-flow fan 310 or only the lower mixed-flow fan 320, as long as the usage requirements can be met.

[0030] The air conditioner unit provided in this embodiment employs an annular evaporator 200 and a mixed-flow fan. The annular evaporator 200 provides comprehensive heat exchange to the surrounding air intake, with a large heat exchange area, thus improving heat exchange efficiency and laying a solid foundation for enhancing the overall cooling and heating efficiency of the unit. Furthermore, the annular evaporator 200 has minimal restriction on the air intake direction, which facilitates increased airflow. The mixed-flow fan is equipped with a high-speed motor, and a conical diffuser is formed in the center of the air duct, with a guide ring on the outer ring, forming an annular accelerating air outlet. A ring of ribs is also provided at the air outlet of the mixed-flow fan to achieve a spiral high-speed airflow, resulting in a large air delivery volume. In summary, this embodiment directly positions the mixed-flow fan at the upper and lower ends of the annular evaporator 200, which is beneficial for both improving air intake and heat exchange efficiency, as well as increasing air delivery volume.

[0031] Specifically, in this embodiment, as Figure 1 and Figure 2 As shown, the air outlets include a top air outlet 102 and a bottom air outlet 104. The air outlet of the upper mixed-flow fan 310 is connected to the top air outlet 102, and the air outlet of the lower mixed-flow fan 320 is connected to the bottom air outlet 104. In this configuration, after the annular evaporator 200 exchanges heat with the incoming air, the upper mixed-flow fan 310 can promptly deliver the heat-exchanged air upwards to the top air outlet 102, and the lower mixed-flow fan 320 can promptly deliver the heat-exchanged air downwards to the bottom air outlet 104. Due to the principle that cold air descends and hot air rises, when the air conditioner is in cooling mode, the upper mixed-flow fan 310 can operate and deliver cold air to the top air outlet 102 so that the cold air can diffuse to the outside of the unit through the top air outlet 102; when the air conditioner is in heating mode, the lower mixed-flow fan 320 can operate and deliver hot air to the bottom air outlet 104 so that the hot air can diffuse to the outside of the unit through the bottom air outlet 104. Of course, both mixed-flow fans can work regardless of whether the air conditioner is in cooling mode, heating mode, or other modes.

[0032] More specifically, in this embodiment, continuing as follows Figure 1 and Figure 2 As shown, the housing 100 includes a main frame 110, a top plate 170, and a bottom plate 180. A top air outlet 102 is formed between the main frame 110 and the top plate 170, and a bottom air outlet 104 is formed between the main frame 110 and the bottom plate 180. An upper air outlet 103 is provided at the top of the main frame 110, and the upper air outlet 103 is connected to the top air outlet 102. A lower air outlet 105 is provided at the bottom of the main frame 110, and the lower air outlet 105 is connected to the bottom air outlet 104.

[0033] More specifically, in this embodiment, both the top air outlet 102 and the bottom air outlet 104 are arranged facing forward. With this arrangement, the air sent upward by the upper mixing fan 310 is blocked by the top plate 170 and then output forward through the top air outlet 102, while the air sent downward by the lower mixing fan 320 is blocked by the bottom plate 180 and then output forward through the bottom air outlet 104.

[0034] In this embodiment, the upper air outlet 103 may be provided with an upper air guide structure, such as an upper air guide plate, which can deliver the air upward and forward to the top air outlet 102.

[0035] In this embodiment, the lower air outlet 105 may be provided with a lower air guide structure, such as a lower air guide plate, which can deliver the air downward and forward, so that the air can be easily output from the bottom air outlet 105.

[0036] Of course, such as Figure 2 and Figure 3 As shown, in this embodiment, the air outlet also includes a main air outlet 101, which is disposed facing forward on the upper part of the housing 100 and is also connected to the air outlet end of the upper mixed-flow fan 310. Whether the air outlet end of the upper mixed-flow fan 310 is connected to the main air outlet 101 or to the upper air outlet 103 can be determined by setting an air guiding device, such as an air duct or air guide plate, to guide the airflow from the upper mixed-flow fan 310. Specifically, if an air duct is set, a valve can be installed between the upward air duct and the air duct guiding the airflow to the main air outlet 101 to select one of the air outlet ducts. Alternatively, the airflow of the two ducts can be controlled by controlling the opening of the valve. If an air guide plate is set, the airflow direction can be controlled by rotating the air guide plate.

[0037] Specifically, in this embodiment, as Figure 2 As shown, the main air outlet 101 is provided with an upper mounting plate 120, which has a hollow structure, and an air outlet plate 130 is provided outside the upper mounting plate 120. In this configuration, the hollow structure of the upper mounting plate 120 can improve the structural strength of the housing 100 in and around the main air outlet 101 while ensuring that the air outlet is not blocked as much as possible.

[0038] Preferably, in this embodiment, the air outlet plate 130 can be a zero-air plate, which is provided with a plurality of zero-air holes (not shown in the figure). Air outlet through the zero-air holes can effectively avoid the phenomenon of air blowing directly on people, thereby improving the user experience. Furthermore, the zero-air plate can be detachably installed on the upper mounting plate 120. For example, the zero-air plate can be magnetically connected to the upper mounting plate 120.

[0039] In this embodiment, as Figure 2 and Figure 4As shown, the lower part of the casing 100 is provided with multiple air inlets along the circumference, and all the air inlets are arranged opposite to the annular evaporator 200. With this arrangement, the air intake area of ​​the air conditioning unit provided in this embodiment is relatively large, thereby effectively increasing the air intake volume. In combination with the annular evaporator 200 with a large heat exchange area and the mixed flow fan with a large air supply volume, the cooling and heating efficiency of the whole unit can be further guaranteed.

[0040] Specifically, in this embodiment, as Figure 2 and Figure 4 As shown, the air inlets include a front air inlet 104, a left rear air inlet 105, a right rear air inlet, and a rear air inlet, wherein the right rear air inlet and the rear air inlet are not shown in the figure.

[0041] Specifically, in this embodiment, the front air vent 104 is provided with a lower mounting plate 150, which has a hollow structure, and an air inlet plate 160 is provided outside the lower mounting plate 150. With this configuration, the hollow structure of the lower mounting plate 150 can improve the structural strength of the housing 100 in and around the front air vent 104 while ensuring that it does not obstruct the air intake as much as possible.

[0042] Preferably, in this embodiment, the air inlet plate 160 can also be a zero-air plate, which is provided with a plurality of zero-air holes (not shown in the figure). Further, in this embodiment, the zero-air plate, which serves as the air inlet plate 160, is detachably mounted on the lower mounting plate 150, for example, it can be magnetically connected to the lower mounting plate 150.

[0043] Specifically, in this embodiment, as Figure 1 and Figure 2 As shown, a waist plate 140 is also provided between the air outlet plate 130 and the air inlet plate 160 in the vertical direction, which can be used as a display plate or a decorative plate.

[0044] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
