Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to a vertical air conditioning indoor unit. Background Technology

[0002] Air conditioners are becoming increasingly widespread as devices used for heating in summer and cooling in winter. Furthermore, there are many different types of air conditioners, such as wall-mounted air conditioners, cabinet air conditioners, central air conditioners, and floor-standing air conditioners. Floor-standing air conditioners, in particular, are aesthetically pleasing because they can conceal the refrigerant pipes connecting the outdoor and indoor units between the indoor unit and the cavity wall, and can be placed in the living room as a decorative element.

[0003] Currently, the air outlet structure of existing vertical air conditioners consists of an air outlet formed at the end of an air duct composed of a volute and a volute tongue, along with an air guide plate at the outlet. Users can then adjust the rotation direction of the air guide plate to direct the airflow from the vertical air conditioner to the area requiring cooling or heating. However, while the airflow near the air guide plate is well guided towards the user's desired direction after the outlet is opened, its guiding effect on airflow moving away from it decreases. This results in poor airflow guidance from the air guide plate and a reduced user experience. Summary of the Invention

[0004] One object of the present invention is to provide a vertical air conditioner indoor unit that can solve at least one of the defects in the prior art.

[0005] A further objective of this invention is to improve the guiding effect of the air guiding components of the indoor unit of a vertical air conditioner, thereby enhancing the user experience.

[0006] Specifically, the present invention provides a vertical air conditioner indoor unit, comprising:

[0007] case;

[0009] The air outlet mechanism, mounted on the housing, includes:

[0010] An air outlet frame is provided on the front and left and right sides of the indoor unit of a vertical air conditioner. An air outlet cavity that connects to the air supply duct is provided between the frame and the front side of the air duct component. An intermediate ventilation zone is provided on the front side of the air outlet cavity to allow the airflow in the air outlet cavity to flow to the indoor space where the indoor unit of the vertical air conditioner is located.

[0011] The air intake assembly is rotatably installed in the air outlet cavity. Its rotation center axis is arranged in the vertical direction and is positioned relative to the central ventilation area.

The multiple inner air-guiding plates are arranged at intervals on one side of the outer air-guiding plate in a direction away from the outer air-guiding plate. The air-guiding channel is located between the top connecting plate, the bottom connecting plate, the inner air-guiding plates and the outer air-guiding plates, as well as between the top connecting plate, the bottom connecting plate and any two inner air-guiding plates.

[0016] Furthermore, the air intake assembly also includes:

[0019] The width of the inner air-guiding plate is smaller than that of the outer air-guiding plate, and the width of multiple inner air-guiding plates decreases as the distance from the outer air-guiding plate increases.

[0020] Furthermore, the air intake assembly is used to restrict the airflow in the outlet cavity from flowing into the indoor space from the intermediate ventilation zone when it is rotated to the point where the outer air intake plate closes the intermediate ventilation zone;

[0021] The air intake assembly is used to guide the airflow in the exhaust cavity from the central ventilation area forward into the indoor space when it is rotated to the position of the air intake channel in the front-back direction;

[0026] The left air guide plate is arranged vertically in the left ventilation zone 1, and its upper and lower ends are rotatably connected to the air outlet frame. It is used to guide the airflow in the air outlet cavity from the left ventilation zone 1 into the indoor space when the left ventilation zone 1 is open.

[0027] Furthermore, the air outlet frame is provided with left and right grille holes on the left and right sides of the air outlet cavity, respectively, to allow airflow within the air outlet cavity to flow into the indoor space where the indoor unit of the vertical air conditioner operates; and both the left and right grille holes extend vertically.

[0028] The rotation center axis of the right guide vane is located at the rear of its right end, and the rotation center axis of the left guide vane is located at the rear of its left end; and,

[0029] The width of the right air guide plate and the width of the left air guide plate are both greater than or equal to the thickness of the air outlet cavity in the front-to-back direction.

[0030] The right-hand air guide plate is used to restrict the airflow in the air outlet cavity from flowing into the indoor space through the right grille hole when it is rotated to the left end and abuts against the right end of the air outlet.

[0031] The left air guide plate is used to restrict the airflow in the air outlet cavity from flowing into the indoor space through the left grille hole when it is rotated to the right end and abuts against the left end of the air outlet.

[0032] Furthermore, the air outlet frame is also equipped with a right ventilation zone 2 and a left ventilation zone 2 on the front side of the air outlet cavity to allow airflow within the air outlet cavity to flow into the indoor space acted upon by the indoor unit of the vertical air conditioner. The right ventilation zone 2 is located to the right of the right ventilation zone 1, and the left ventilation zone 2 is located to the left of the left ventilation zone 1.

[0037] The housing also includes an air outlet frame disposed between the air inlet grille and the air outlet mechanism. The air outlet frame includes a connecting outer frame with a passage opening formed in the middle, a first baffle plate connected to the left end of the connecting outer frame and extending to the passage opening and connected to the air duct component, and a second baffle plate connected to the right end of the connecting outer frame and extending to the passage opening and connected to the air duct component. The air outlet cavity is located between the air outlet frame, the first baffle plate and the second baffle plate.

[0038] Furthermore, the air duct components include:

[0039] The volute and volute tongue are interconnected, and the air supply duct is formed between the volute and volute tongue. The first baffle is connected to the volute tongue, and the second baffle is connected to the volute.

[0040] The indoor unit of this vertical air conditioner features an air outlet mechanism, including an air outlet frame and an air intake assembly. An air outlet cavity communicating with the air supply duct is provided between the air outlet frame and the front side of the duct component. The air intake assembly is rotatably disposed within the air outlet cavity, with its rotation axis arranged vertically and positioned relative to the intermediate ventilation zone. Multiple air intake channels are provided within the air intake assembly, and two air intake ports on the outer peripheral side of each channel are positioned opposite each other. This allows the airflow within the air outlet cavity to be guided into the indoor space through these multiple channels and ports, ensuring effective guidance of the airflow exiting the intermediate ventilation zone. Therefore, this invention improves the guiding effect of the airflow guiding components in a vertical air conditioner indoor unit, enhancing the user experience.

Figure 1 This is a schematic diagram of the structure of a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the air outlet mechanism in a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the air intake assembly in a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 4 This is a cross-sectional schematic diagram of a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 5 This is one of the schematic diagrams of the air outlet of a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 6This is a second schematic diagram of the air outlet of a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 7 This is the third schematic diagram of the air outlet of a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 8 This is the fourth schematic diagram of the air outlet of a vertical air conditioner indoor unit according to an embodiment of the present invention; Figure 9 This is a schematic diagram of the air outlet frame of a vertical air conditioner indoor unit according to an embodiment of the present invention.

[0059] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the indoor unit of the vertical air conditioner includes a housing 100, an air duct component 200, and an air outlet mechanism 300. The air duct component 200 is disposed within the housing 100, and an air supply duct 210 is disposed within the air duct component 200. The air outlet mechanism 300 is disposed on the housing 100, and the air outlet mechanism 300 includes an air outlet frame 310 and an air intake assembly 320. The air outlet frame 310 is disposed on the front side and left and right sides of the indoor unit of the vertical air conditioner. An air outlet cavity 220 communicating with the air supply duct 210 is disposed between the air outlet frame 310 and the front side of the air duct component 200. An air outlet cavity 220 for allowing air to exit is provided on the front side of the air outlet cavity 220 on the air outlet frame 310. The airflow in cavity 220 flows to the middle ventilation zone 3113 of the indoor space where the indoor unit of the vertical air conditioner is located; the air intake assembly 320 is rotatably disposed in the air outlet cavity 220, the rotation center axis of the air intake assembly 320 is arranged in the vertical direction, and the air intake assembly 320 is disposed relative to the middle ventilation zone 3113. Multiple air intake channels 321 are disposed in the air intake assembly 320, and the two air intake ports 3211 of each air intake channel 321 are disposed opposite to each other on the outer peripheral side of the air intake assembly 320.

[0060] Since the indoor unit of the vertical air conditioner in this embodiment has an air outlet mechanism 300, and the air outlet mechanism 300 includes an air outlet frame 310 and an air intake assembly 320, an air outlet cavity 220 communicating with the air supply duct 210 is provided between the air outlet frame 310 and the front side of the air duct component 200, and the air intake assembly 320 is rotatably disposed in the air outlet cavity 220. The rotation center axis of the air intake assembly 320 is arranged in the vertical direction, and the air intake assembly 320 is disposed relative to the intermediate ventilation zone 3113. Multiple air intake channels 321 are provided in the air intake assembly 320, and two air intake ports 3211 of each air intake channel 321 are disposed opposite to each other on the outer peripheral side of the air intake assembly 320. Thus, the airflow in the air outlet cavity 220 can be guided into the indoor space through multiple air intake channels 321 and their air intake ports 3211, ensuring the guiding effect of the airflow flowing out of the intermediate ventilation zone 3113. Therefore, this embodiment can improve the guiding effect of the air guiding components of the indoor unit of a vertical air conditioner, thereby enhancing the user experience.

[0061] Reference Figure 3 In this embodiment, the air intake assembly 320 includes a top connecting plate 322, a bottom connecting plate 323, an outer air intake plate 324, and a plurality of inner air intake plates 325. The top connecting plate 322 is rotatably connected to the top of the air outlet frame 310; the bottom connecting plate 323 is rotatably connected to the bottom of the air outlet frame 310; the top ends of the outer air intake plate 324 and the plurality of inner air intake plates 325 are all connected to the top connecting plate 322, and the bottom ends of the outer air intake plate 324 and the plurality of inner air intake plates 325 are all connected to the bottom connecting plate 323. The plurality of inner air intake plates 325 are arranged at intervals on one side of the outer air intake plate 324 in a direction away from the outer air intake plate 324. The air intake channel 321 is located between the top connecting plate 322, the bottom connecting plate 323, the inner air intake plates 325 and the outer air intake plate 324, and between the top connecting plate 322, the bottom connecting plate 323 and any two inner air intake plates 325. This allows the air intake assembly 320 to guide the airflow in the air outlet 220 to the indoor space through multiple air intake channels 321 and their air intake ports 3211.

[0062] Reference Figure 4 In this embodiment, the air supply duct 210 is provided with an air outlet 250 on the front side of the air duct component 200 for connecting the air supply duct 210 and the air outlet cavity 220, and the intermediate ventilation zone 3113 and the air outlet 250 are arranged opposite to each other.

[0063] It is understandable that by setting the intermediate ventilation zone 3113 and the air outlet 250 relative to each other, the airflow in the air supply duct 210 can flow directly into the indoor space through the intermediate ventilation zone 3113 without changing direction, thereby ensuring the flow rate and air pressure of the outflowing air.

[0064] Reference Figure 3 and Figure 4 In this embodiment, the width of the inner air guide plate 325 is smaller than the width of the outer air guide plate 324, and the width of the multiple inner air guide plates 325 decreases as the distance from the outer air guide plate 324 increases.

[0065] It is understandable that the width of the inner air-guiding plate 325 is smaller than the width of the outer air-guiding plate 324, and the width of the multiple inner air-guiding plates 325 decreases as the distance from the outer air-guiding plate 324 increases. This arrangement can prevent the air-guiding assembly 320 from contacting the air duct component 200 or the components at the left and right ends of the middle ventilation area 3113 (e.g., the left air guide plate 333 and the right air guide plate 332 described below) during the rotation of the air outlet cavity 220, thus ensuring the normal air-guiding function of the air-guiding assembly 320. Furthermore, this arrangement allows the air-guiding assembly 320 to maintain a certain distance from the wall of the supply air duct 210 when guiding air to the left or right, ensuring that the airflow from the supply air duct 210 can flow well into the air-guiding duct and be guided into the indoor space, preventing the air-guiding assembly 320 from abutting against the wall of the supply air duct 210, which would prevent the airflow from the supply air duct 210 from entering the air-guiding duct.

[0066] Reference Figure 4 In this embodiment, the shape of the outer contour of the cross-section of the air intake component 320 can be triangular.

[0067] Reference Figure 3 In this embodiment, the air intake assembly 320 further includes a plurality of intermediate connecting plates 326. The plurality of intermediate connecting plates 326 are spaced apart along the vertical direction between the top connecting plate 322 and the bottom connecting plate 323, and are connected to the outer air intake plate 324 and the plurality of inner air intake plates 325. This ensures the overall connection stability of the air intake assembly 320.

[0068] Reference Figure 5 In this embodiment, the air intake assembly 320 is used to restrict the airflow in the air outlet cavity 220 from flowing into the indoor space from the intermediate ventilation zone 3113 when it is rotated to the outer air intake plate 324 to close the intermediate ventilation zone 3113. Thus, the indoor unit of the vertical air conditioner can close the intermediate ventilation zone 3113 when ventilation is not required in the intermediate ventilation zone 3113.

[0069] Reference Figure 6 In this embodiment, the air intake assembly 320 is used to guide the airflow in the air outlet cavity 220 to flow forward from the middle ventilation zone 3113 into the indoor space when it is rotated to the position where the air intake channel 321 is set in the front-back direction, so that the indoor unit of the vertical air conditioner can achieve forward air outlet in the middle part of the front.

[0070] Reference Figure 7 In this embodiment, the air intake assembly 320 is used to guide the airflow in the air outlet cavity 220 from the middle ventilation zone 3113 into the indoor space when it is rotated to the left tilting position of the air intake channel 321, so that the indoor unit of the vertical air conditioner can achieve left air outlet in the middle part of the front.

[0071] It should be noted that, in addition to achieving the above-mentioned air outlet direction and air outlet mode, the air duct assembly 320 can also achieve, for example, an air outlet mode in which air is discharged to the right through the central ventilation zone 3113, a sweeping mode in which the air duct assembly 320 rotates back and forth, or an intermittent air outlet mode in which the air duct assembly 320 rotates in one direction. Examples will not be described here. Any scheme with the same structure as the air duct assembly 320 in this embodiment but achieving different air outlet directions / modes should be considered to be within the protection scope of this invention.

[0072] Furthermore, in existing technologies, to ensure sufficient airflow distance, the width of the air outlet of an air conditioner is typically set to be narrow, resulting in a very small airflow range for floor-standing air conditioners. Moreover, floor-standing air conditioners can only simultaneously open one air outlet to deliver air into the room or simultaneously close that one air outlet, leading to a limited airflow method and a reduced user experience.

[0073] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the air outlet frame 310 is further provided with a right ventilation zone 3112 and a left ventilation zone 3114 on the front side of the air outlet cavity 220 to allow the airflow in the air outlet cavity 220 to flow to the indoor space where the indoor unit of the vertical air conditioner is located. The right ventilation zone 3112 is located to the right of the middle ventilation zone 3113, and the left ventilation zone 3114 is located to the left of the middle ventilation zone 3113. In addition, the air outlet mechanism 300 also includes a right air guide plate 332 and a left air guide plate 333. A right air guide plate 332 is arranged vertically at the right ventilation zone 3112, and the upper and lower ends of the right air guide plate 332 are rotatably connected to the air outlet frame 310. The right air guide plate 332 is used to guide the airflow in the air outlet cavity 220 into the indoor space when the right ventilation zone 3112 is opened. A left air guide plate 333 is arranged vertically at the left ventilation zone 3114, and the upper and lower ends of the left air guide plate 333 are rotatably connected to the air outlet frame 310. The left air guide plate 333 is used to guide the airflow in the air outlet cavity 220 into the indoor space when the left ventilation zone 3114 is opened.

[0074] Understandably, by coordinating the central ventilation zone 3113, right ventilation zone 3112, and left ventilation zone 3114 with the air outlet cavity 220, the airflow within the air outlet cavity 220 can pass through the central ventilation zone 3113, right ventilation zone 3112, and / or left ventilation zone 3114, thus expanding the air outlet range of the indoor unit of the vertical air conditioner. Furthermore, by configuring the right air guide plate 332, left air guide plate 333, and air intake assembly 320, the airflow within the air outlet cavity 220 can be switched to flow into the areas of the indoor space that need to pass through the ventilation opening 311 (central ventilation zone 3113, right ventilation zone 3112, and left ventilation zone 3114), thereby diversifying the air outlet mode of the indoor unit of the vertical air conditioner and improving the user experience.

[0075] Reference Figure 4 In this embodiment, the air outlet frame 310 is provided with a left grille hole 312 and a right grille hole 313 on the left and right sides of the air outlet cavity 220, respectively, for allowing the airflow in the air outlet cavity 220 to flow to the indoor space where the indoor unit of the vertical air conditioner is located, and the left grille hole 312 and the right grille hole 313 are both arranged to extend in the vertical direction.

[0076] It is understandable that by setting the air outlet cavity 220 and the left grille hole 312 and right grille hole 313 located on the left and right sides of the air outlet cavity 220, the airflow in the air outlet cavity 220 can enter the indoor space to the left and right through the left grille hole 312 and right grille hole 313, further expanding the air supply range of the vertical air conditioner indoor unit and further diversifying the air supply mode of the vertical air conditioner indoor unit.

[0077] Reference Figure 8 In this embodiment, the rotation center axis of the right air guide plate 332 is located at the rear side of its right end, and the rotation center axis of the left air guide plate 333 is located at the rear side of its left end; and the width D of the right air guide plate 332 and the width B of the left air guide plate 333 are both greater than or equal to the thickness K of the air outlet cavity 220 in the front-back direction; the right air guide plate 332 is used to restrict the airflow in the air outlet cavity 220 from flowing into the indoor space through the right grille hole 313 when it is rotated to the left end abutting the right end of the air outlet 250; the left air guide plate 333 is used to restrict the airflow in the air outlet cavity 220 from flowing into the indoor space through the left grille hole 312 when it is rotated to the right end abutting the left end of the air outlet 250.

[0078] It is understandable that by setting the rotation center axis and width of the right air guide plate 332 and the left air guide plate 333, the airflow in the indoor unit of the vertical air conditioner can be restricted from flowing into the indoor space through the left grille hole 312 and the right grille hole 313 when the airflow in the air outlet cavity 220 flows into the indoor space from the right ventilation zone 3112 and / or the left ventilation zone 3114. This ensures the air outlet distance from the right ventilation zone 3112 and / or the left ventilation zone 3114 into the indoor space.

[0079] Reference Figure 2 and Figure 4 In this embodiment, the air outlet frame 310 is further provided with a right ventilation zone 3111 and a left ventilation zone 3115 on the front side of the air outlet cavity 220 to allow the airflow in the air outlet cavity 220 to flow to the indoor space where the indoor unit of the vertical air conditioner is located. The right ventilation zone 3111 is located to the right of the right ventilation zone 3112, and the left ventilation zone 3115 is located to the left of the left ventilation zone 3114. Furthermore, the air outlet mechanism 300 also includes a right second air guide plate 331 and a left second air guide plate 334: the right second air guide plate 331 is arranged in the vertical direction at the right ventilation zone 3111, and the upper and lower ends of the right second air guide plate 331 are rotatably connected to the air outlet frame 310; the left second air guide plate 334 is arranged in the vertical direction at the left ventilation zone 3115, and the upper and lower ends of the left second air guide plate 334 are rotatably connected to the air outlet frame 310.
