Description

Technical Field

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

[0002] Wall-mounted air conditioners are indoor units installed on interior walls. In modern society, living spaces are often quite compact, and the thickness of the wall-mounted unit significantly impacts its space-consuming nature and aesthetics. Reducing the thickness of the unit offers more options for visual appeal and space utilization. Furthermore, many current mainstream air conditioner indoor units, such as some wall-mounted units, share the same air duct for both cooling and heating. This limits the airflow range, and during cooling, the denser cold air, blowing downwards, results in a cold-to-warm sensation, causing discomfort such as cold feet and a hot head. Utility Model Content

In the second state, the outlet of the cross-flow fan duct formed by the baffle walls and the volutes faces the second air outlet assembly. The drive member is used to drive the mounting bracket to rotate relative to the housing so that the fan component switches between the first state and the second state.

[0009] During air supply operation, the fan component drives air to enter the housing from one of the first air outlet assembly and the second air outlet assembly and exit the housing from the other, and the air exchanges heat with the heat exchanger during its flow within the housing.

[0010] In some embodiments, the fan component is located above the heat exchanger.

[0011] In some embodiments, the impeller is fixedly mounted on the mounting bracket or fixedly mounted on the housing.

[0012] In some embodiments, the impeller is fixedly mounted on the mounting bracket, and the rotation axis of the mounting bracket relative to the housing is not coaxial with the rotation axis of the impeller.

[0013] In some embodiments, the air outlet component further includes a first extension wall and a second extension wall, the heat exchanger is located between the second air outlet assembly and the fan component, one end of the first extension wall and the second extension wall is fixedly connected to the first air outlet assembly, in the first state, the outlet end of the volute tongue is aligned with the end of the first extension wall away from the first air outlet assembly, the outlet end of the shielding wall is aligned with the end of the second extension wall away from the first air outlet assembly, and the volute tongue, the shielding wall, the first extension wall and the second extension wall form an air duct for supplying air to the first air outlet assembly.

[0014] In some embodiments, the first air outlet assembly includes a first air outlet, a second air outlet, a first air guide plate for closing and opening the first air outlet, and a second air guide plate for closing and opening the second air outlet. One end of the first extension wall and the second extension wall are respectively connected to the first air outlet. In the first state, the volute tongue, the shielding wall, the first extension wall, and the second extension wall form an air duct for supplying air to the first air outlet.

[0015] In some embodiments, the first air vent assembly includes a first air vent and a first air guide plate for closing and opening the first air vent. One end of the first extension wall and the second extension wall are respectively connected to the first air vent. In the first state, the first air guide plate opens the first air vent and the first air guide plate and the outlet end of the shielding wall have the same tilt angle relative to the vertical direction.

[0016] In some embodiments, the heat exchanger includes a first heat exchange section and a second heat exchange section arranged in a V-shape, the V-shaped opening of the heat exchanger facing the fan component, and in the second state, the outlet of the air duct of the cross-flow fan formed by the shielding wall and the volute tongue faces the V-shaped opening of the heat exchanger.

[0019] Based on the wall-mounted air conditioner provided by this utility model, by arranging the first air outlet assembly and the second air outlet assembly at the upper and lower ends of the casing respectively, and arranging the fan component, heat exchanger, first air outlet assembly, and second air outlet assembly in the same direction, with the fan component and heat exchanger both located between the first air outlet assembly and the second air outlet assembly, the thickness of the wall-mounted air conditioner can be reduced. This results in a smaller space occupation after the air conditioner is installed on the wall, making it more aesthetically pleasing. Simultaneously, by switching between the first and second states during cooling and heating, the air conditioner can ensure that during cooling, cold air is output from the top, avoiding direct airflow to people, and that the cold air sinks downwards under gravity, providing a more comprehensive cooling effect and greater comfort. During heating, hot air is output from the bottom; the low density of hot air allows it to rise, improving the uniformity of heating and achieving a more comprehensive heating effect.

[0030] The wall-mounted air conditioner in this embodiment includes a housing 1, an air outlet component, a heat exchanger 31, and a fan component.

[0031] The air vent component includes a first air vent assembly 21 and a second air vent assembly 22. Each air vent assembly includes an air vent for air intake or exhaust. One of the first air vent assembly 21 and the second air vent assembly 22 is located at the upper end of the housing 1, and the other is located at the lower end of the housing 1. The terms "upper end" and "lower end" are used with reference to the wall-mounted air conditioner unit after it is installed on the wall. The descriptions of "upper" and "lower" in this application all refer to the position of the wall-mounted air conditioner unit after it is installed on the wall. The upper end of the wall-mounted air conditioner unit is the uppermost end, and the lower end is the lowermost end. In the embodiment shown in the figure, the first air vent assembly is located at the upper end of the housing 1, and the second air vent assembly is located at the lower end of the housing 1.

[0032] Heat exchanger 31 is located inside shell 1. Refrigerant is introduced into heat exchanger 31 to exchange heat with the air passing through it. When the air conditioner is cooling, heat exchanger 3 acts as an evaporator for the refrigerant; when the air conditioner is heating, heat exchanger 3 acts as a condenser for the refrigerant.

[0033] The fan component is housed within the casing 1. The fan component, heat exchanger 31, first air outlet assembly 21, and second air outlet assembly 22 are located in the same direction, with both the fan component and heat exchanger 31 situated between the first air outlet assembly 21 and the second air outlet assembly 22. The fan component, heat exchanger 31, first air outlet assembly 21, and second air outlet assembly 22 being in the same direction means they are on the same straight line. The first air outlet assembly 21 and second air outlet assembly 22 are located at the upper and lower ends of the casing 1, respectively, thus forming a straight line extending vertically. In the embodiment shown in the figure, the fan component, heat exchanger 31, first air outlet assembly 21, and second air outlet assembly 22 are all located in the vertical direction.

[0034] During air supply operation, the fan component drives air to enter the housing 1 from one of the first air outlet assembly 21 and the second air outlet assembly 22 and exit the housing 1 from the other, and the air exchanges heat with the heat exchanger 31 during its flow within the housing 1.

[0035] In such Figures 1 to 3 In the embodiment shown, the fan component includes a mounting bracket 41 rotatably disposed relative to the housing 1, a drive component drivenly connected to the mounting bracket 41, and a cross-flow fan.

[0036] A cross-flow fan, also known as a cross-flow blower, was proposed by the French engineer Mortier in 1892. Its impeller is a multi-bladed, long cylindrical shape with forward-curving multi-wing blades. The structure of a cross-flow fan includes an impeller, a baffle wall, and a volute. The baffle wall partially blocks the outer circumference of the impeller, and the volute separates the inlet and outlet sides of the impeller's outer circumference. This causes the vortex center of the vortex entering the impeller to move closer to the volute. Therefore, when the impeller rotates, the airflow enters from the unblocked inlet side of the impeller's outer circumference, passes through the impeller's interior, and exits from the outlet side between the baffle wall and the volute, forming the working airflow. The baffle wall and the volute are both important working components of the cross-flow fan. In the embodiment shown in the figure, the cross-flow fan includes an impeller and a baffle wall 43 and a volute 44 mounted on a mounting frame 41 for air outlet from the impeller 42. The baffle wall 43 and the volute 44 are arranged opposite each other on both sides of the fan section. The fan component has a first state and a second state. In the first state, the outlet of the air duct of the cross-flow fan formed by the baffle wall 43 and the volute tongue 44 faces the first air outlet assembly 21. In the second state, the outlet of the air duct of the cross-flow fan formed by the baffle wall 43 and the volute tongue 44 faces the second air outlet assembly 22. The driving member is used to drive the mounting bracket 41 to rotate relative to the housing 1 so that the fan component switches between the first state and the second state. In this embodiment, both the baffle wall 43 and the volute tongue are mounted on the mounting bracket, and the mounting bracket can rotate relative to the housing, for example, as shown in the figure. Figure 1The fan rotates around axis 411, thereby causing the shielding wall 43 and volute tongue 44 to rotate as a whole. When the air outlet duct formed by the shielding wall 43 and volute tongue 44 faces the first air outlet assembly 21, the fan component is in the first state, such as... Figure 2 As shown, the cross-flow fan draws air in from the second air outlet assembly and delivers air to the first air outlet assembly through the air outlet duct formed by the baffle wall 43 and the volute tongue 44. When the air outlet duct formed by the baffle wall 43 and the volute tongue 44 faces the second air outlet assembly 22, the fan component is in the second state, as shown. Figure 3 As shown, the cross-flow fan draws air in from the first air outlet assembly and delivers air to the second air outlet assembly through the air outlet duct formed by the baffle wall 43 and the volute tongue 44. Since the first and second air outlet assemblies are located at opposite ends of the housing, the wall-mounted air conditioner in this embodiment can switch between discharging air to the upper end and discharging air to the lower end of the housing. When the air conditioner is cooling or heating, the cold air density is high, and the cold air blows downwards, which can easily lead to cold feet and a hot head, resulting in an uncomfortable experience.

[0037] In this embodiment of the wall-mounted air conditioner, the first air vent assembly 21 and the second air vent assembly 22 are respectively arranged at the upper and lower ends of the housing 1. The fan component, heat exchanger 31, first air vent assembly 21, and second air vent assembly 22 are arranged in the same direction, with the fan component and heat exchanger 31 both located between the first air vent assembly 21 and the second air vent assembly 22. This arrangement reduces the thickness (horizontal dimension) of the wall-mounted air conditioner, resulting in a smaller footprint and a more aesthetically pleasing appearance. Furthermore, during cooling and heating, switching between the first and second states allows the cold air to be output from the top, avoiding direct airflow to people. The cold air also sinks downwards due to gravity, providing a more comprehensive and comfortable cooling effect. During heating, hot air is output from the bottom. The hot air has a low density and can rise, improving the uniformity of heating and achieving a more comprehensive heating effect.

[0038] In some embodiments, such as Figures 1 to 3 As shown, the fan assembly is located above the heat exchanger 31. The heat exchanger is arranged below the fan assembly. When a water collection tray is installed below the heat exchanger to collect condensate, it can reduce the impact on the flow of air passing through the heat exchanger and also facilitate the arrangement.

[0039] In some embodiments, the impeller is fixedly mounted on a mounting bracket or fixedly mounted on a housing. In such cases... Figure 1-3In the illustrated embodiment, the cross-flow fan includes an impeller 42 mounted on a mounting bracket 41, a baffle wall 43 for air outlet from the impeller 42, and a volute 44. When the baffle wall 43, impeller, and volute are all mounted on the mounting bracket, the mounting bracket rotates relative to the housing, for example as... Figure 1 The rotating shaft 411 shown can drive the shielding wall 43, volute tongue 44 and impeller 42 to rotate as a whole. When switching between the first state and the second state, the shielding wall 43, volute tongue 44 and impeller 42 will not produce relative displacement, which helps to maintain the stability of the gap, relative position and other aspects of the fit between the shielding wall 43, volute tongue 44 and impeller 42, and improve the structural reliability. When the impeller is fixedly installed on the housing, the rotating shaft of the mounting bracket 41 relative to the housing 1 is coaxial with the rotating shaft of the impeller 42. The shielding wall 43 and the volute are both installed on the mounting bracket. The mounting bracket can rotate relative to the housing. The impeller is installed on the housing but not on the mounting bracket. The rotating shaft of the mounting bracket is coaxial with the rotating shaft of the impeller. Thus, the rotation of the mounting bracket drives the shielding wall 43 and the volute 44 to rotate as a whole. The shielding wall 43 and the volute 44 always surround the impeller, playing their role in shielding the air intake and separating the air intake and exhaust on the outer circumference of the impeller. Since the rotation of the mounting bracket only needs to drive the shielding wall 43 and the volute 44, the rotational load is small, and the switching device can be set more simply.

[0040] In some embodiments, such as Figures 1 to 3 As shown, the impeller is fixedly mounted on the mounting bracket, and the rotation axis of the mounting bracket relative to the housing is not coaxial with the rotation axis of the impeller. This coaxial arrangement allows for a larger impeller size. Furthermore, when switching between the first and second states, and the mounting bracket drives the baffle wall 43, the volute tongue 44, and the impeller 42 to rotate as a whole, the impeller 42 can move closer to the components between the first air inlet assembly 21 and the second air inlet assembly 22 to generate air intake in both states. In other words, the impeller is closer to its air inlet, thereby improving the impeller's air intake efficiency.

[0041] In some embodiments, such as Figures 1 to 3As shown, the air outlet component also includes a first extension wall 231 and a second extension wall 232. The heat exchanger 31 is located between the second air outlet assembly 22 and the fan component. One end of the first extension wall 231 and the second extension wall 232 is fixedly connected to the first air outlet assembly 21. In the first state, the outlet end of the volute tongue 44 is aligned with the end of the first extension wall 231 away from the first air outlet assembly 21, and the outlet end of the shielding wall 43 is aligned with the end of the second extension wall 232 away from the first air outlet assembly 21. The volute tongue 44, the shielding wall 43, the first extension wall 231 and the second extension wall 232 form an air duct for supplying air to the first air outlet assembly 21. The alignment of the outlet end of the volute tongue 44 with the end of the first extension wall 231 furthest from the first air vent assembly 21 means that the outlet end of the volute tongue 44 is directly connected to the end of the first extension wall 231 furthest from the first air vent assembly 21, or when there is a gap between them, the extension direction of the outlet end of the volute tongue 44 is the same as the extension direction of the end of the first extension wall 231 furthest from the first air vent assembly 21. Similarly, the alignment of the outlet end of the shielding wall 43 with the end of the second extension wall 232 furthest from the first air vent assembly 21 means that the outlet end of the shielding wall 43 is directly connected to the end of the second extension wall 232 furthest from the first air vent assembly 21, or when there is a gap between them, the extension direction of the outlet end of the shielding wall 43 is the same as the extension direction of the end of the second extension wall 232 furthest from the first air vent assembly 21. Thus, in the first state, the volute tongue 44, the shielding wall 43, the first extension wall 231, and the second extension wall 232 can form an air duct that directly supplies air to the first air vent assembly 21. In this embodiment, the heat exchanger 31 is arranged between the second air outlet assembly 22 and the fan component, and a first extension wall 231 and a second extension wall 232 are provided. In the first state, the outlet end of the volute tongue and the shielding wall of the cross-flow fan faces the first air outlet assembly. The first extension wall 231 and the second extension wall 232 can guide the airflow more efficiently, improving the airflow efficiency. In the second state, the outlet end of the volute tongue and the shielding wall of the cross-flow fan faces the heat exchanger. Since the heat exchangers are close together, it is not necessary to provide an extension wall to achieve efficient airflow to the heat exchanger. At the same time, if the heat exchanger is set as a V-shaped heat exchanger as shown in the figure, the heat exchanger structure can receive the airflow from the cross-flow fan more efficiently. Thus, the structure switching between "long shielding wall and long volute tongue" and "short shielding wall and short volute tongue" can be realized in the first and second states, achieving efficient and accurate airflow from the cross-flow fan, improving the airflow utilization efficiency, and resulting in a compact and efficient structure.

[0042] In some embodiments, such as Figures 1 to 3As shown, the first air outlet assembly 21 includes a first air outlet 251, a second air outlet 252, a first air guide plate 241 for closing and opening the first air outlet 251, and a second air guide plate 242 for closing and opening the second air outlet 252. One end of the first extension wall 231 and the second extension wall 232 are respectively connected to the first air outlet 251. In the first state, the volute tongue 44, the shielding wall 43, the first extension wall 231, and the second extension wall 232 form an air duct for supplying air to the first air outlet 251. In this embodiment, in the first state, the cross-flow fan discharges air to the first air outlet assembly. Since the air discharge of the cross-flow fan is relatively concentrated, the air discharge demand can be met by using one air outlet, thus achieving efficient air discharge by only opening the first air guide plate 241. In the second state, the first air outlet assembly serves as the air inlet side of the cross-flow fan. Both the first air guide plate 241 and the second air guide plate 242 are open, thereby utilizing the first air outlet and the second air outlet to provide air intake for the cross-flow fan. This better meets the large-area air intake requirements of the cross-flow fan. In other words, this embodiment can better meet the air outlet requirements of the cross-flow fan in the first state and the air intake requirements in the second state.

[0043] In some embodiments, such as Figure 2 As shown, the first air outlet assembly 21 includes a first air outlet 251 and a first air guide plate 241 for closing and opening the first air outlet 251. One end of the first extension wall 231 and the second extension wall 232 are respectively connected to the first air outlet 251. In the first state, the first air guide plate 241 opens the first air outlet 251 and the first air guide plate 241 and the outlet end of the shielding wall 43 have the same tilt angle relative to the vertical direction. That is, in the first state, when the first air guide plate 241 is fully open, the extension direction of the first air guide plate is the same as the extension direction of the outlet end of the shielding wall 43. Thus, the air output from the shielding wall 43 can be better guided by the air guide plate in the fully open state, realizing an efficient air outlet mode.

[0044] In some embodiments, as shown in the figure, the heat exchanger 31 includes a first heat exchange section 311 and a second heat exchange section 312 arranged in a V-shape. The V-shaped opening of the heat exchanger 31 faces the fan component. In a second state, the outlet of the air duct of the cross-flow fan formed by the baffle wall 43 and the volute tongue 44 faces the V-shaped opening of the heat exchanger 31. By configuring the heat exchanger 31 to include the first heat exchange section 311 and the second heat exchange section 312 arranged in a V-shape, and with the V-shaped opening facing the impeller, this embodiment achieves concentrated and efficient airflow between the fan and the heat exchanger, whether the cross-flow fan outlets air to the heat exchanger in the first state or draws air from the heat exchanger in the second state, thereby improving the airflow efficiency between the two.

[0045] In some embodiments, such as Figure 2 and Figure 3As shown, the second air outlet assembly 22 includes a third air outlet 253, a fourth air outlet 254, a third air guide plate 243 for closing and opening the third air outlet 253, and a fourth air guide plate 244 for closing and opening the fourth air outlet 254. The third air outlet 253 and the fourth air outlet 254 are respectively opposite to the first heat exchange section 311 and the second heat exchange section 312. In this embodiment, by setting the third air outlet and the fourth air outlet, as well as the third air guide plate and the fourth air guide plate, the two air outlets and the air guide plate respectively correspond to one heat exchange section of the heat exchanger, that is, the air outlets face one heat exchange section. Thus, in the first state, the third air outlet and the fourth air outlet can respectively deliver a large amount of air to the first heat exchange section 311 and the second heat exchange section 312 for heat exchange. In the second state, the first heat exchange section 311 and the second heat exchange section 312 can also output the heat-exchanged air to the outside through the third air outlet and the fourth air outlet, thereby improving the heat exchange efficiency of the heat exchanger and better meeting the air intake and exhaust requirements of the cross-flow fan.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the wall-mounted air conditioner also includes a water collection tray 32. The fan assembly is located above the heat exchanger 31. The second air outlet assembly 22 includes a connecting portion connecting the third air outlet 253 and the fourth air outlet 254. The water collection tray 32 is located between the heat exchanger 31 and the second air outlet assembly 22 and surrounds the bottom of the heat exchanger 31 near the second air outlet assembly 22. The water collection tray 32 is disposed on the connecting portion. In this embodiment, by arranging the water collection tray directly below the heat exchanger on the connecting portion connecting the third and fourth air outlets, and by surrounding the bottom of the heat exchanger, the water collection tray can effectively collect condensate from the heat exchanger while causing less interference to the air inlet and outlet of the heat exchanger, thus ensuring the air inlet and outlet efficiency and heat exchange efficiency of the heat exchanger.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
