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 and air conditioner. 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 duct formed by a volute and a volute tongue, with an air outlet at the end and a guide vane at the outlet. Users can then adjust the direction of the guide vane's rotation to direct the airflow to the desired cooling or heating area. However, the air outlet is typically located at the front of the air conditioner, limiting its airflow to that direction and resulting in a very limited airflow range. Furthermore, vertical air conditioners can only deliver air into the room through this single outlet, and regardless of the guide vane's rotation, the airflow is limited to the forward, left-front, or right-front directions, leading to a monotonous airflow pattern and a reduced user experience. Summary of the Invention

[0074] Reference Figure 1 as well as Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, the vertical air conditioner indoor unit includes a housing 100, an air duct component 200, and an air guiding mechanism 400. The housing 100 includes air outlet grilles 110 located on its front side and left and right sides, and the air outlet grilles 110 are provided with a plurality of ventilation sections 111; the air duct component 200 is disposed inside the housing 100, and an air supply duct 210 is disposed inside the air duct component 200, and an air outlet cavity 300 communicating with the air supply duct 210 is disposed between the front side of the air duct component 200 and the air outlet grille 110; the air guiding mechanism 400 is rotatably disposed at at least part of the ventilation sections 111, and the air guiding mechanism 400 is used to switch the airflow in the air outlet cavity 300 to the ventilation section 111 that needs to flow outside the housing 100, and to adjust the air outlet direction of the vertical air conditioner indoor unit.

[0075] Because the vertical air conditioner indoor unit of this embodiment has air outlet grilles 110 on its front and left and right sides, and multiple ventilation sections 111 on the air outlet grilles 110 to enable air outlet, and an air outlet cavity 300 between the front side of the air duct 200 and the air outlet grille 110 to allow the airflow of the supply air duct 210 to flow to the air outlet grille 110, the vertical air conditioner indoor unit can outlet air from the left, right and front sides, effectively increasing the air outlet range; and the vertical air conditioner indoor unit can supply air into the indoor space through multiple ventilation sections 111, and with the help of the air guide mechanism 400 used to switch the airflow in the air outlet cavity 300 to the ventilation section 111 that needs to flow to the outside of the housing 100 and to adjust the air outlet direction of the vertical air conditioner indoor unit, the vertical air conditioner indoor unit can have an air supply mode that supplies air through different sides, different areas or different ventilation sections 111 of the air outlet grille 110, and an air outlet direction that outlets air to the left and / or to the right. Therefore, the vertical air conditioner indoor unit of this embodiment can have a wide air supply range and diverse air supply methods, thereby improving the user experience.

[0076] Furthermore, since the amount of airflow that the airflow in the air outlet cavity 300 needs to pass through to reach the outside of the housing 100 varies depending on the number of ventilation sections 111 or the amount of airflow that different ventilation sections 111 allow to flow out of the air outlet cavity 300 to the outside of the housing 100, the vertical air conditioner indoor unit of the present invention can also adjust the airflow according to the user's needs to improve the user experience.

[0077] Reference Figure 1 as well as Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, the plurality of ventilation sections 111 include air outlets 1111 and a plurality of air vents 1112. This allows airflow within the air outlet cavity 300 to flow to the outside of the housing 100.

[0078] Reference Figure 1 as well as Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, multiple air outlets 1112 are located on the left and right sides of the air outlet 1111.

[0079] Reference Figure 1 as well as Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, the air outlet grille 110 includes a first grille strip group 112, a second grille strip group 113, a third grille strip group 114, and a fourth grille strip group 115. The first grille strip group 112 is located on the right side of the air outlet 1111 and in front of the air outlet cavity 300; the second grille strip group 113 is located on the left side of the air outlet 1111 and in front of the air outlet cavity 300; the third grille strip group 114 is located on the right side of the air outlet cavity 300; and the fourth grille strip group 115 is located on the left side of the air outlet cavity 300. The grille strips of each grille strip group are arranged vertically, and the air outlet 1112 is located between any two grille strips. Therefore, the vertical air conditioner indoor unit of this embodiment can have a larger air outlet area on the front side. Compared to the prior art where only a fixed air outlet 1111 is set on the front side, it has a larger air outlet range, further improving the user experience.

[0080] Reference Figure 1 as well as Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18In this embodiment, the air supply duct 210 is provided with an air supply port 211 on the front side of the air duct component 200 for connecting the air supply duct 210 and the air outlet 300. The air outlet 1111 and the air supply port 211 are arranged opposite to each other. Furthermore, when the air outlet 1111 is open, the airflow from the air supply vent 211 flows directly through the air outlet 1111 into the indoor space outside the housing 100; when the air outlet 1111 is closed, the airflow from the air supply vent 211 can flow to the first grille group 112, the second grille group 113, the third grille group 114, and the fourth grille group 115. By simply setting an air guide component at the air outlet 1111, it is possible to control whether airflow flows out of the air outlets 1112 on the first grille group 112, the second grille group 113, and the third grille group 114, so that the air guide mechanism 400 can have a simple structure, which can reduce the cost of the vertical air conditioner indoor unit.

[0081] Reference Figure 1 and 2 In the first embodiment of the air guiding mechanism 400 in this example, the air guiding mechanism 400 includes an air guiding plate 410. The air guiding plate 410 is rotatably disposed at the air outlet 1111 and is arranged in the vertical direction. The air guiding plate 410 is used to open or close the air outlet 1111 and to restrict or allow the airflow from the air supply duct 210 to flow through the partial air outlet hole 1112. This allows the air guiding mechanism 400 to switch the airflow in the air outlet cavity 300 to the ventilation section 111 that needs to flow to the outside of the housing 100, and to adjust the air outlet direction of the vertical air conditioner indoor unit.

[0082] Reference Figure 3 In this embodiment, the air guide plate 410 is used to guide the airflow in the air outlet cavity 300 to flow through the air outlet holes 1112 on the third grille group 114 and the fourth grille group 115 to the outside of the housing 100 when the air outlet 1111 is closed, and to adjust the air outlet of the vertical air conditioner indoor unit to at least the left and right.

[0083] Reference Figure 1 and 2 In this embodiment, the rotation center axis of the air guide plate 410 is set in the vertical direction. Therefore, the left and right ends of the air guide plate 410 can rotate around the rotation center axis.

[0084] Reference Figure 4 In this embodiment, the air guide plate 410 is also used to guide the airflow in the air outlet cavity 300 to at least flow through the air outlet 1111 to the outside of the housing 100 when it is arranged at its left and right ends in the front-back direction, and to adjust the indoor unit of the vertical air conditioner to at least face forward airflow.

[0085] Reference Figure 2In this embodiment, the rotation center axis of the air guide plate 410 is located at the middle of the width direction of the air guide plate 410, and the rotation center axis of the air guide plate 410 is located at the middle of the width direction of the air outlet 1111. The air outlet 1111 includes a left region located between the left end of the air outlet 1111 and the rotation center axis of the air guide plate 410, and a right region located between the right end of the air outlet 1111 and the rotation center axis of the air guide plate 410. Therefore, the air guide plate 410 can allow the airflow from the air supply duct 210 to flow only through a portion of the air outlet 1111 (e.g., the left or right region) into the indoor space outside the housing 100, thus refining the control of the airflow from the vertical air conditioner indoor unit and further diversifying the air outlet modes of the vertical air conditioner indoor unit to meet the user's needs for more air outlet modes and improve the user experience.

[0086] Reference Figure 3 In this embodiment, the distance H between the left or right end of the air guide plate 410 and the rotation center axis of the air guide plate 410 is greater than the thickness L in the front-back direction of the air outlet cavity 300. Therefore, the air guide plate 410 may have a state in which its left end abuts against the left end of the air outlet 211, or its right end abuts against the right end of the air outlet 211.

[0087] Reference Figure 3 In this embodiment, the air guide plate 410 is also used to guide the airflow in the air outlet cavity 300 to at least flow through the right region and the air outlet 1112 on the first grille strip group 112 when its right end faces the right front and its left end abuts against the left end of the air outlet 211, and to adjust the air outlet of the vertical air conditioner indoor unit to at least face the right front.

[0088] Reference Figure 6 In this embodiment, the air guide plate 410 is also used to guide the airflow in the air outlet cavity 300 to at least flow through the left area and the air outlet hole 1112 on the second grille strip group 113 when its left end faces the left front and its right end abuts against the right end of the air outlet 211, and to adjust the air outlet of the vertical air conditioner indoor unit to at least face the left front.

[0089] As can be seen from the foregoing embodiments and implementation methods, the air guide plate 410, through its various states, can switch the airflow within the air outlet cavity 300 to the ventilation section 111 outside the housing 100, and adjust the air outlet direction of the indoor unit of the vertical air conditioner. However, it can only restrict the flow of air out of the air supply duct 210 towards the air outlet hole 1112 on one side of the air outlet 1111. It cannot separately control the two streams of air flowing from the air supply duct 210 towards the air outlet holes 1112 on both sides of the air outlet 1111, nor can it simultaneously restrict the flow of air out of the air supply duct 210 towards the air outlet holes 1112 on both sides of the air outlet 1111. Consequently, when the user needs the vertical air conditioner to dissipate air through the air outlet 1111, the air pressure leaks from the air outlet holes 1112 on the air outlet grille 110, resulting in significant air loss and a greatly reduced air outlet distance, thus reducing the user experience. To eliminate this defect, refer to... Figure 1 and Figure 7 In the second embodiment of the air guiding mechanism 400 in this embodiment, the air guiding mechanism 400 includes a left guide plate 420 and a right guide plate 430 arranged side by side in the horizontal direction. The left guide plate 420 and the right guide plate 430 are rotatably disposed at the air outlet 1111. The left guide plate 420 and the right guide plate 430 are both arranged in the vertical direction. The rotation center axis of the left guide plate 420 and the right guide plate 430 are both set in the vertical direction. The rotation center axis of the left guide plate 420 is set close to the left end of the left guide plate 420 adjacent to the left end of the air outlet 1111. The rotation center axis of the right guide plate 430 is set close to the right end of the right guide plate 430 adjacent to the right end of the air outlet 1111.

[0090] Since the vertical air conditioner indoor unit of this embodiment includes a left guide plate 420 and a right guide plate 430 rotatably disposed at the air outlet 1111, the left guide plate 420 and the right guide plate 430 can respectively open or close the area of ​​their corresponding air outlet 1111; and the left guide plate 420 can restrict or allow the airflow from the air supply duct 210 to flow towards at least a portion of the air outlet 1112 on the left side of the air outlet 1111, and the right guide plate 430 can restrict or allow the airflow from the air supply duct 210 to flow towards at least a portion of the air outlet 1112 on the right side of the air outlet 1111. Furthermore, the left guide plate 420 and the right guide plate 430 can switch the airflow within the air outlet cavity 300 to the ventilation section 111 (air outlet 1111 and / or air outlet hole 1112) that needs to flow outside the housing 100, and adjust the air outlet direction of the vertical air conditioner indoor unit. Simultaneously, they also restrict the airflow from the air supply duct 210 to the air outlet holes 1112 on both sides of the air outlet 1111. This reduces airflow leakage when the user needs the vertical air conditioner to exit through the air outlet 1111, minimizing wind loss and ensuring the air outlet distance. Therefore, the vertical air conditioner indoor unit of this embodiment can have a wide air supply range and diverse air supply methods, effectively improving the user experience.

[0091] Furthermore, two guide plates are provided at the air outlet 1111. The air guiding mechanism 400 can ensure that the airflow from the air supply duct 210 flows only through a portion of the air outlet 1111 (e.g., the left or right portion in the following embodiment) to the indoor space outside the housing 100. This refines the control of the airflow from the vertical air conditioner indoor unit, further diversifies the air outlet mode of the vertical air conditioner indoor unit, meets the user's needs for more air outlet modes, and improves the user experience.

[0092] Reference Figure 8 In this embodiment, the left guide plate 420 and the right guide plate 430 are used to guide the airflow in the air outlet cavity 300 to flow through the air outlet holes 1112 on the third grille group 114 and the fourth grille group 115 to the outside of the housing 100 when the air outlet 1111 is closed together, and to adjust the air outlet of the vertical air conditioner indoor unit to at least the left and right.

[0093] Reference Figure 7 In this embodiment, the rotation center axis of the left guide plate 420 is located at the rear side of the left guide plate 420; the rotation center axis of the right guide plate 430 is located at the rear side of the right guide plate 430. Therefore, the right end of the left guide plate 420 and the left end of the right guide plate 430 can open the air outlet 1111 to the rear, so that the left guide plate 420 and the right guide plate 430 can guide the airflow to the first grille bar group 112, the second grille bar group 113, the third grille bar group 114 and the fourth grille bar group 115.

[0094] Reference Figure 9 In this embodiment, the width N of the left guide plate 420 or the width M of the right guide plate 430 is greater than or equal to the thickness L in the front-back direction of the air outlet cavity 300. Therefore, the left guide plate 420 may have its right end abutting against the left end of the air outlet 211, and the right guide plate 430 may have its left end abutting against the right end of the air outlet 211.

[0095] In a modified embodiment, the width N of the left guide plate 420 or the width M of the right guide plate 430 is less than the thickness L in the front-back direction of the air outlet cavity 300. As a result, the left guide plate 420 may have a state of blocking at least part of the air outlet 1112 of the second grille bar group 113, and the right guide plate 430 may have a state of blocking at least part of the air outlet 1112 of the first grille bar group 112, so as to simultaneously restrict the airflow from the air supply duct 210 to flow towards the air outlet 1112 on both sides of the air outlet 1111.

[0096] Furthermore, in existing vertical air conditioners, the structure of the air outlet duct and the size of the air outlet 1111 are not customizable by the user. Therefore, if a user wants a longer air outlet distance, they can increase the fan speed. However, the fan speed is limited by power, resulting in the air outlet distance not meeting the user's needs and reducing the user experience. Moreover, with a fixed or already maximum fan speed, a vertical air conditioner can have its air outlet 1111 designed to be larger to meet the user's wide-area airflow needs, or smaller to meet the user's long-distance airflow needs. However, the user cannot change the size of the air outlet 1111, thus preventing the same vertical air conditioner from meeting both wide-area and long-distance airflow needs, further reducing the user experience.

[0097] Reference Figure 9 In this embodiment, the distance P between the rotation center axis of the left guide plate 420 and the rotation center axis of the right guide plate 430 is less than or equal to the width Q of the air outlet 211. Therefore, the left guide plate 420 can have its left end facing right front, and the right guide plate 430 can have its right end facing left front.

[0098] Reference Figure 9 In this embodiment, the left guide plate 420 and the right guide plate 430 are also used to guide the airflow in the air outlet 300 to at least flow through the air outlet 1111 to the outside of the housing 100 when the right end of the left guide plate 420 abuts against the left end of the air outlet 211 and the left end of the right guide plate 430 abuts against the right end of the air outlet 211 and the right end of the right guide plate 430 faces the left front, and adjust the indoor unit of the vertical air conditioner to at least vent air forward.

[0099] In this embodiment of the vertical air conditioner indoor unit, the air guiding mechanism 400 can have a state where the right end of the left guide plate 420 abuts against the left end of the air outlet 211, with the left end of the left guide plate 420 facing to the right front, and the left end of the right guide plate 430 abuts against the right end of the air outlet 211, with the right end of the right guide plate 430 facing to the left front. In this state, the airflow exiting the housing 100 is not constrained by the air outlet 1111, but by the left guide plate 420 and the right guide plate 430. Furthermore, in the direction of airflow flow, the distance between the left guide plate 420 and the right guide plate 430 becomes smaller and smaller, thereby reducing the air outlet area of ​​the airflow exiting the housing 100 and increasing the airflow velocity to improve the air outlet distance of the vertical air conditioner indoor unit. In conjunction with other situations or states of the left guide plate 420 and the right guide plate 430 described above and below in this embodiment, it can be seen that the vertical air conditioner indoor unit of this embodiment can have various forms of large-range air supply. Therefore, a single vertical air conditioner indoor unit in this embodiment can meet the user's two needs: wide-area air supply and long-distance air supply, effectively improving the user experience.

[0100] In this embodiment, the air outlet 1111 includes the left region corresponding to the left guide plate 420 and the right region corresponding to the right guide plate 430.

[0101] Reference Figure 10 In this embodiment, the left guide plate 420 and the right guide plate 430 are also used to guide the airflow in the air outlet 300 to at least flow through the air outlet 1112 on the first grille bar group 112 and the left area to the outside of the housing 100 when the right end of the left guide plate 420 abuts against the left end of the air outlet 211, the left end of the left guide plate 420 faces the right front, and the right guide plate 430 closes the right area, and adjust the air outlet of the vertical air conditioner indoor unit to at least face the right front.

[0102] Reference Figure 11 In this embodiment, the left guide plate 420 and the right guide plate 430 are also used to abut the right end of the air outlet 211 at the left end of the right guide plate 430, with the right end of the right guide plate 430 facing the left front. When the left guide plate 420 closes the left area, the airflow in the air outlet cavity 300 is guided to flow through the air outlet hole 1112 on the second grille bar group 113 and the right area to the outside of the housing 100, and the vertical air conditioner indoor unit is adjusted to vent air at least to the left front.

[0103] As can be seen from the foregoing embodiments and the implementation of the air guiding mechanism 400 as the left guide plate 420 and the right guide plate 430, the left guide plate 420 and the right guide plate 430 reduce air leakage and air loss when the user needs the vertical air conditioner to discharge air through the air outlet 1111, thus ensuring the air outlet distance. However, the direction of the airflow from the air outlet 1111 cannot be changed according to the user's needs, which reduces the user experience. To eliminate this defect, refer to... Figure 1 and Figure 12 In the third embodiment of the air guiding mechanism 400 in this embodiment, the air guiding mechanism 400 includes a left guide plate 420, a middle guide plate 440 and a right guide plate 430 arranged horizontally side by side. The left guide plate 420, the middle guide plate 440 and the right guide plate 430 are all arranged in the vertical direction. The rotation center axis of the left guide plate 420 and the right guide plate 430 are both set in the vertical direction. The rotation center axis of the left guide plate 420 is set close to the left end of the left guide plate 420 adjacent to the left end of the air outlet 1111. The rotation center axis of the right guide plate 430 is set close to the right end of the right guide plate 430 adjacent to the right end of the air outlet 1111. The middle guide plate 440 is disposed between the left guide plate 420 and the right guide plate 430.

[0104] Since the vertical air conditioner indoor unit of this embodiment includes a left guide plate 420, a middle guide plate 440 and a right guide plate 430 that are rotatably disposed, the left guide plate 420 and the right guide plate 430 can respectively open or close the area of ​​their corresponding air outlet 1111; and the left guide plate 420 can restrict or allow the airflow from the air supply duct 210 to flow towards at least a portion of the air outlet 1112 on the left side of the air outlet 1111, and the right guide plate 430 can restrict or allow the airflow from the air supply duct 210 to flow towards at least a portion of the air outlet 1112 on the right side of the air outlet 1111. Furthermore, the left guide plate 420 and right guide plate 430 can switch the airflow within the air outlet cavity 300 to the ventilation section 111 (air outlet 1111 and / or air outlet hole 1112) that needs to flow outside the housing 100, and adjust the airflow direction of the vertical air conditioner indoor unit. Simultaneously, they also restrict the airflow from the air supply duct 210 to the air outlet holes 1112 on both sides of the air outlet 1111. This reduces airflow leakage when the user needs the vertical air conditioner to exit through the air outlet 1111, reduces wind loss, ensures airflow distance, and effectively improves the user experience. Moreover, when the middle guide plate 440 opens the area corresponding to its air outlet 1111, it can also change the direction of the airflow exiting from at least the central area of ​​the air outlet 1111 according to user needs. Therefore, the vertical air conditioner indoor unit of this embodiment can have a wide air supply range and diverse air supply methods, effectively improving the user experience.

[0105] Furthermore, three guide plates are provided at the air outlet 1111. The air guiding mechanism 400 can ensure that the airflow from the air supply duct 210 flows only through a portion of the air outlet 1111 (e.g., the left, middle, or right portion as described in the following embodiment) into the indoor space outside the housing 100. This refines the control of the airflow from the vertical air conditioner indoor unit, further diversifies the air outlet mode of the vertical air conditioner indoor unit, meets the user's needs for more air outlet modes, and improves the user experience.

[0106] Reference Figure 1 and Figure 12 In this embodiment, the rotation center axis of the middle guide plate 440 is set in the vertical direction, and the rotation center axis of the middle guide plate 440 can be set in the middle of the width direction of the middle guide plate 440 and the middle of the width direction of the air outlet 1111. Therefore, the left and right ends of the middle guide plate 440 can rotate around its rotation center axis.

[0107] Furthermore, in existing vertical air conditioners with multiple guide plates, each guide plate is designed to be as short as possible, ensuring that the total width of all guide plates is the same as the width of the air outlet 1111. This prevents the guide plates from overlapping when they are jointly closing the air outlet 1111, and allows the front sides of the guide plates to be on the same plane, maintaining a good aesthetic appearance on the front of the vertical air conditioner. However, the short width of the guide plates significantly reduces their air guiding effect, making it difficult to effectively direct the airflow to the area where the user needs cooling or heating, thus reducing the user experience of the vertical air conditioner.

[0108] Reference Figure 12 and Figure 13 In this embodiment, the right end of the left guide plate 420 bends backward and extends to form a first step plate 421, then bends to the right and extends to form a second step plate 422. The left end of the right guide plate 430 bends backward and extends to form a third step plate 431, then bends to the left and extends to form a fourth step plate 432. When the left guide plate 420, the middle guide plate 440 and the right guide plate 430 jointly close the air outlet 1111, the left end of the middle guide plate 440 overlaps the front of the second step plate 422, and the right end of the middle guide plate 440 overlaps the front of the fourth step plate 432.

[0109] In this embodiment, the right end of the left guide plate 420 is provided with a first stepped structure including a first stepped plate 421 and a second stepped plate 422, and the right end of the right guide plate 430 is provided with a second stepped structure including a third stepped plate 431 and a fourth stepped plate. Therefore, when the left guide plate 420, the middle guide plate 440, and the right guide plate 430 jointly close the air outlet 1111, the front sides of the left guide plate 420, the middle guide plate 440, and the right guide plate 430 can remain on the same plane, ensuring the aesthetics of the vertical air conditioner indoor unit. Simultaneously, the left guide plate 420, the middle guide plate 440, and the right guide plate 430 can be allowed to be set relatively long to ensure their air guiding effect. Therefore, the vertical air conditioner indoor unit of this embodiment can effectively improve the user experience.

[0110] Reference Figure 13In this embodiment, the left guide plate 420, the middle guide plate 440 and the right guide plate 430 are used to guide the airflow in the air outlet cavity 300 to flow through the air outlet holes 1112 on the third grille group 114 and the fourth grille group 115 to the outside of the housing 100 when the air outlet 1111 is closed together, and to adjust the air outlet of the vertical air conditioner indoor unit to at least the left and right.

[0111] Reference Figure 14 In this embodiment, the left guide plate 420, the middle guide plate 440 and the right guide plate 430 are also used to guide the airflow in the air outlet 300 to at least flow through the air outlet 211 to the outside of the housing 100 when the left and right ends of the middle guide plate 440 are arranged in the front and rear directions, and to adjust the indoor unit of the vertical air conditioner to at least vent air forward.

[0112] At this time, the left guide plate 420 can be in the state of closing the area corresponding to the left guide plate 420 of the air outlet 1111, or it can be in the state of opening the area corresponding to the left guide plate 420 of the air outlet 1111; the right guide plate 430 can be in the state of closing the area corresponding to the right guide plate 430 of the air outlet 1111, or it can be in the state of opening the area corresponding to the right guide plate 430 of the air outlet 1111. Both can guide the airflow in the air outlet cavity 300 to at least flow through the air supply port 211 to the outside of the casing 100, and adjust the indoor unit of the vertical air conditioner to at least face forward.

[0113] Reference Figure 12 In this embodiment, the rotation center axis of the left guide plate 420 is located at the rear side of the left guide plate 420, and the rotation center axis of the right guide plate 430 is located at the rear side of the right guide plate 430. As a result, the right end of the left guide plate 420 and the left end of the right guide plate 430 can open the air outlet 1111 to the rear, so that the left guide plate 420 and the right guide plate 430 can guide the airflow to the first grille bar group 112, the second grille bar group 113, the third grille bar group 114 and the fourth grille bar group 115.

[0114] Reference Figure 15 In this embodiment, the width N of the left guide plate 420 or the width M of the right guide plate 430 is greater than or equal to the thickness L in the front-back direction of the air outlet cavity 300. Therefore, the left guide plate 420 may have its right end abutting against the left end of the air outlet 211, and the right guide plate 430 may have its left end abutting against the right end of the air outlet 211.

[0115] In a modified embodiment, the width N of the left guide plate 420 or the width M of the right guide plate 430 is less than the thickness L in the front-back direction of the air outlet cavity 300. As a result, the left guide plate 420 may have a state of blocking at least part of the air outlet 1112 of the second grille bar group 113, and the right guide plate 430 may have a state of blocking at least part of the air outlet 1112 of the first grille bar group 112, so as to simultaneously restrict the airflow from the air supply duct 210 to flow towards the air outlet 1112 on both sides of the air outlet 1111.

[0116] Reference Figure 16 In this embodiment, the distance P between the rotation center axis of the left guide plate 420 and the rotation center axis of the right guide plate 430 is greater than the width Q of the air outlet 211. Furthermore, the left guide plate 420 may have its left end facing the right front; the right guide plate 430 may have its right end facing the left front.

[0117] In this embodiment, the air outlet 1111 includes the left region corresponding to the left guide plate 420, the middle region corresponding to the middle guide plate 440, and the right region corresponding to the right guide plate 430.

[0118] Reference Figure 15 In this embodiment, the left guide plate 420, the middle guide plate 440, and the right guide plate 430 are also arranged along the front-back direction at the left and right ends of the middle guide plate 440. The right end of the left guide plate 420 abuts against the left end of the air outlet 211, and the left end of the left guide plate 420 faces to the right front. With the right guide plate 430 closing the right area, the airflow in the air outlet cavity 300 is guided to flow through at least the air outlet 1112 on the first grille bar group 112, and the indoor unit of the vertical air conditioner is adjusted to discharge air at least to the right front. In addition, in this case, the left guide plate 420, the middle guide plate 440, and the right guide plate 430 can also guide the airflow in the air outlet cavity 300 to flow through the left and middle areas of the air outlet 1111, and can also adjust the indoor unit of the air conditioner to discharge air forward.

[0119] Reference Figure 16 In this embodiment, the left guide plate 420, the middle guide plate 440, and the right guide plate 430 are also arranged along the front-back direction at the left and right ends of the middle guide plate 440. The left end of the right guide plate 430 abuts against the right end of the air outlet 211, and the right end of the right guide plate 430 faces the left front. When the left guide plate 420 closes the left area, the airflow in the air outlet cavity 300 is guided to flow through the air outlet 1112 on the second grille strip group 113 at least, and the indoor unit of the vertical air conditioner is adjusted to discharge air at least to the left front. In addition, in this case, the left guide plate 420, the middle guide plate 440, and the right guide plate 430 can also guide the airflow in the air outlet cavity 300 to flow through the right and middle areas of the air outlet 1111, and can also adjust the indoor unit of the air conditioner to discharge air forward.

[0120] In this embodiment, the left guide plate 420, the middle guide plate 440, and the right guide plate 430 are also used to ensure the air outlet distance of the airflow from the air outlet 1111 when the middle guide plate 440 closes the middle area, the right end of the left guide plate 420 abuts against the left end of the air outlet 211 with the left end of the left guide plate 420 facing to the right front, and the left end of the right guide plate 430 abuts against the right end of the air outlet 211 with the right end of the right guide plate 430 facing to the left front. This can effectively ensure the air outlet distance of the airflow from the air outlet 1111 and ensure the user experience.

[0121] In the above embodiments, whether airflow exits from the air outlet 1112 of the air outlet grille 110 is controlled by a guide plate located at the air outlet 1111. As a result, the airflow from the air outlet 1112 and the air outlet 1111 affects each other, making it impossible to individually control the airflow towards the air outlet 1112 and the air outlet 1111. To eliminate this deficiency, refer to... Figure 1 and Figure 17 , Figure 18 In the fourth embodiment of the air guiding mechanism 400 in this embodiment, the air guiding mechanism 400 includes an air guiding component 450 and an air ducting component 460. The air guiding component 450 is rotatably disposed at the air outlet 1111 and is used to open or close at least a portion of the air outlet 1111. The air ducting component 460 is rotatably disposed at at least a portion of the air outlet 1112 and is used to restrict or allow the airflow from the air supply duct 210 to flow towards at least a portion of the air outlet 1112.

[0122] Since the vertical air conditioner indoor unit of this embodiment has an air guiding mechanism 400 including an air guiding member 450 that can open or close at least a portion of the air outlet 1111, and an air duct member 460 that can restrict or allow the airflow from the air supply duct 210 to flow towards at least a portion of the air outlet 1112, the air guiding mechanism 400 can switch the airflow in the air outlet cavity 300 to the ventilation section 111 (air outlet 1111 and / or air outlet 1112) that needs to flow to the outside of the housing 100, and adjust the air outlet direction of the vertical air conditioner indoor unit. Furthermore, the airflow to the air outlet 1112 and the air vent 1111 can be controlled separately by the air intake component 460 and the air guide component 450, avoiding the situation where the air outlet states of the air outlet 1112 and the air vent 1111 affect each other. This allows for individual control of the airflow to the air outlet 1112 and the air vent 1111, refining the control of the airflow of the vertical air conditioner indoor unit and further diversifying the air outlet modes of the vertical air conditioner indoor unit to meet the needs of users for more air outlet modes. Therefore, the vertical air conditioner indoor unit of this embodiment can have a wide air supply range and diversified air supply modes, effectively improving the user experience.

[0123] Reference Figure 1 and Figure 17 In this embodiment, the air-guiding component 460 includes a left air-guiding plate 461 and a right air-guiding plate 462, both of which are arranged in the vertical direction.

[0124] Reference Figure 17 In this embodiment, the rotation center axis of the left air-guiding plate 461 is located at one end of the left air-guiding plate 461 in a vertical direction, and the rotation center axis of the right air-guiding plate 462 is located at one end of the right air-guiding plate 462 in a vertical direction. The rotation center axis of the left air-guiding plate 461 is located near the second grid bar group 113 and the fourth grid bar group 115, and the rotation center axis of the right air-guiding plate 462 is located near the first grid bar group 112 and the third grid bar group 114. Therefore, the left air-guiding plate 461 can control the airflow flowing to the air outlets 1112 on the second grid bar group 113 and the fourth grid bar group 115, and the right air-guiding plate 462 can control the airflow flowing to the air outlets 1112 on the first grid bar group 112 and the third grid bar group 114, so that the air-guiding member 460 can restrict or allow the airflow exiting the air supply duct 210 to flow towards at least some of the air outlets 1112. Specifically, the left air intake plate 461 can control whether the airflow exiting the air supply duct 210 flows to the second grille group 113 or to the air outlet 1112 on the fourth grille group 115, and the right air intake plate 462 can control whether the airflow exiting the air supply duct 210 flows to the first grille group 112 or to the air outlet 1112 on the third grille group 114. This further refines the control of the airflow from the vertical air conditioner indoor unit and diversifies the air outlet mode of the vertical air conditioner indoor unit.

[0125] In addition, the left air intake plate 461 and the right air intake plate 462 can be installed inside the air outlet cavity 300 or outside the air outlet cavity 300. In order to ensure the aesthetics of the vertical air conditioner indoor unit, it is preferable to install the left air intake plate 461 and the right air intake plate 462 inside the air outlet cavity 300.

[0126] Reference Figure 18In a modified embodiment, the rotation center axis of the left air-guiding plate 461 is located at one end of the left air-guiding plate 461 in a vertical direction, and the rotation center axis of the right air-guiding plate 462 is located at one end of the right air-guiding plate 462 in a vertical direction. The rotation center axis of the left air-guiding plate 461 is located at the left end of the air outlet 1111, and the rotation center axis of the right air-guiding plate 462 is located at the right end of the air outlet 1111. Therefore, the left air-guiding plate 461 can control the airflow flowing to the air outlets 1112 on the second grid bar group 113 and the fourth grid bar group 115, and the right air-guiding plate 462 can control the airflow flowing to the air outlets 1112 on the first grid bar group 112 and the third grid bar group 114, so that the air-guiding member 460 can restrict or allow the airflow exiting the air supply duct 210 to flow towards at least some of the air outlets 1112. Specifically, the left air intake plate 461 can control whether the airflow flowing out of the air supply duct 210 flows to the air outlet 1112 on the fourth grille group 115, and the right air intake plate 462 can control whether the airflow flowing out of the air supply duct 210 flows to the air outlet 1112 on the third grille group 114.

[0127] Reference Figure 19 In this embodiment, the air guide component 450 and the air duct component 460 are used to guide the airflow in the air outlet cavity 300 to at least flow through the air outlets 1112 on the third grille group 114 and the fourth grille group 115 to the outside of the housing 100 when the air guide component 450 closes the air outlet 1111, the left air duct 461 blocks the air outlet 1112 on the second grille group 113, and the right air duct 462 blocks the air outlet 1112 on the first grille group 112, and adjust the indoor unit of the vertical air conditioner to at least vent air to the left and right.

[0128] Reference Figure 17 In this embodiment, the air guiding component 450 includes a left guide plate 420 and a right guide plate 430 arranged side by side in the horizontal direction. The left guide plate 420 and the right guide plate 430 are rotatably disposed at the air outlet 1111, and both the left guide plate 420 and the right guide plate 430 are arranged in the vertical direction. By providing two guide plates at the air outlet 1111, the air guiding mechanism 400 can ensure that the airflow from the air supply duct 210 flows only through a portion of the air outlet 1111 (e.g., the left or right portion in the following embodiment) into the indoor space outside the housing 100, thereby refining the control of the airflow from the vertical air conditioner indoor unit and diversifying the air outlet mode of the vertical air conditioner indoor unit.

[0129] Reference Figure 1 and Figure 17In this embodiment, the rotation center axes of the left guide plate 420 and the right guide plate 430 are both set in the vertical direction; thus, the left end and the right end of the left guide plate 420 can rotate around the rotation center axis of the left guide plate 420, and the left end and the right end of the right guide plate 430 can rotate around the rotation center axis of the right guide plate 430.

[0130] Reference Figure 20 In this embodiment, the distance P between the rotation center axis of the left guide plate 420 and the rotation center axis of the right guide plate 430 is less than the width Q of the air outlet 211. Therefore, regardless of whether the left guide plate 420 and the right guide plate 430 are open or closed at the air outlet 1111, or whether the airflow from the air outlet 1111 is guided to a corresponding area in the indoor space according to user needs, the left guide plate 420 and the right guide plate 430 will not affect the airflow to the outlet holes of the first grille group 112, the second grille group 113, the third grille group 114, and the fourth grille group 115.

[0131] In a modified embodiment, the air guiding member 450 may include three or more guide plates, which are rotatably disposed at the air outlet 1111 and arranged in a vertical direction. The guide plates can be in a state where they are either closed or open at the air outlet 1111. Furthermore, the distance between the rotation center axes of the leftmost and rightmost guide plates is less than the width of the air inlet 211. Therefore, when both ends of the left guide plate 420 and the right guide plate 430 are arranged in a front-back direction, the left guide plate 420 and the right guide plate 430 can guide the airflow exiting the air supply duct 210 toward the air outlet cavity 300.

[0132] Reference Figure 17 In this embodiment, the rotation center axis of the left guide plate 420 is located at the middle of the width direction of the left guide plate 420, and the rotation center axis of the right guide plate 430 is located at the middle of the width direction of the right guide plate 430.

[0133] Reference Figure 20 In this embodiment, the air guide component 450 and the air duct component 460 are used to guide the airflow in the air outlet cavity 300 to at least flow through the air outlet 1111, the air outlet 1112 on the third grille group 114 and the fourth grille group 115 to the outside of the housing 100 when the left guide plate 420 and the right guide plate 430 are arranged in the front-rear direction, the left air duct 461 is blocked at the air outlet 1112 on the second grille group 113 and the right air duct 462 is blocked at the air outlet 1112 on the first grille group 112, and the air outlet 1112 on the third grille group 114 and the fourth grille group 115. This also adjusts the indoor unit of the vertical air conditioner to at least vent to the left, to the right and to the front.

[0134] Reference Figure 23In this embodiment, the width R of the left air intake plate 461 is the same as the width S of the second grille bar group 113, and the width T of the right air intake plate 462 is the same as the width U of the first grille bar group 112. Thus, when the left air intake plate 461 blocks the second grille bar group 113 and allows the airflow from the air supply duct 210 to flow to the air outlet 1112 on the fourth grille bar group 115, it can effectively prevent airflow from leaking out of the air outlet 1112 on the second grille bar group 113; and when the right air intake plate 462 blocks the first grille bar group 112 and allows the airflow from the air supply duct 210 to flow to the air outlet 1112 on the third grille bar group 114, it can effectively prevent airflow from leaking out of the air outlet 1112 on the first grille bar group 112.

[0135] Reference Figure 23 In this embodiment, the width R of the left air intake plate 461 is greater than the thickness L of the air outlet cavity 300 in the front-back direction, and the width T of the right air intake plate 462 is greater than the thickness L of the air outlet cavity 300 in the front-back direction. Furthermore, the right air guide plate can have a state that restricts the airflow from the air supply duct 210 to flow towards the air outlet 1112 on the first grille group 112 and allows the airflow from the air supply duct 210 to flow towards the air outlet 1112 on the third grille group 114, and a state that allows the airflow from the air supply duct 210 to flow towards the air outlet 1112 on the first grille group 112 and restricts the airflow from the air supply duct 210 to flow towards the air outlet 1112 on the third grille group 114 (for example, in the following embodiments, the end of the right air guide plate 462 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 to the left rear and the end of the left air guide plate 461 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 to the right rear).

[0136] In a modified embodiment, the width R of the left air guide plate 461 is equal to the thickness L in the front-back direction of the air outlet cavity 300, and the width T of the right air guide plate 462 is equal to the thickness L in the front-back direction of the air outlet cavity 300. Furthermore, the right air guide plate can have a state that restricts the flow of air out of the air supply duct 210 to the air outlet 1112 on the first grille group 112 and allows the flow of air out of the air supply duct 210 to the air outlet 1112 on the third grille group 114, and a state that allows the flow of air out of the air supply duct 210 to the air outlet 1112 on the first grille group 112 and restricts the flow of air out of the air supply duct 210 to the air outlet 1112 on the third grille group 114 (for example, the right air guide plate 462 blocking the air outlet 1112 on the third grille group 114 and the left air guide plate 461 blocking the air outlet 1112 on the fourth grille group 115).

[0137] Reference Figure 21In this embodiment, the air guide component 450 and the air duct component 460 are used to guide the airflow in the air outlet 300 to at least flow through the air outlets 1112 on the first grille group 112 and the fourth grille group 115 to the outside of the housing 100 when the left guide plate 420 and the right guide plate 430 close the air outlet 1111, the left air duct 461 blocks the air outlet 1112 on the second grille group 113, and the end of the right air duct 462 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 (e.g., the first baffle plate 132 in the following embodiment) to the left and rear, and adjust the air outlet of the vertical air conditioner indoor unit to at least the left and right front.

[0138] Reference Figure 22 In this embodiment, the air guide component 450 and the air duct component 460 are used to guide the airflow in the air outlet cavity 300 to at least flow through the air outlets 1112 on the second grille group 113 and the third grille group 114 to the outside of the housing 100 when the left guide plate 420 and the right guide plate 430 close the air outlet 1111, the end of the left air duct 461 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 (e.g., the second baffle plate 133 in the following embodiment) to the right rear, and the right air duct 462 blocks the air outlet 1112 on the first grille group 112, and adjust the air outlet of the vertical air conditioner indoor unit to at least to the right and to the left front.

[0139] Reference Figure 22 In this embodiment, the air guide member 450 and the air duct member 460 are used to guide the airflow in the air outlet 300 to at least pass through the air outlet holes 1112 on the first grille bar group 112 and the second grille bar group 113 to the outside of the housing 100 when the air outlet 1111 of the left guide plate 420 and the right guide plate 430 are closed, the end of the left air duct 461 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 to the right rear, and the end of the right air duct 462 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 to the left rear. This also adjusts the vertical air conditioner indoor unit to discharge air at least to the left front and right front. Additionally, in this case, the vertical air conditioner indoor unit can also be adjusted to discharge air at least to the front.

[0140] Reference Figure 24In this embodiment, the air guide component 450 and the air duct component 460 are used to guide the airflow in the air outlet cavity 300 to at least flow through the air outlet 1111, the air outlet holes 1112 on the first grille bar group 112 and the second grille bar group 113 to the outside of the housing 100 when the left guide plate 420 and the right guide plate 430 are arranged in the front-rear direction, the end of the left air duct 461 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 in the right rear direction, and the end of the right air duct 462 away from its rotation center axis abuts against the rear wall of the air outlet cavity 300 in the left rear direction. As can be seen, in this case, compared with the prior art which only supplies air from the air outlet 1111, the air pressure of the airflow flowing out of the air supply duct will be released in the air outlet cavity 300, and can flow to the indoor space outside the housing 100 through the air outlet holes 1112 on the first grille bar group 112 and the second grille bar group 113, so as to ensure the air outlet range of the vertical air conditioner indoor unit.

[0141] Reference Figure 1 as well as Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, the housing 100 also includes an air inlet grille 120 located at its rear side to filter the cleanliness of the airflow entering the housing 100.

[0142] Reference Figure 1 , Figure 25 as well as Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, the housing 100 further includes an air outlet frame 130 disposed between the air inlet grille 120 and the air outlet grille 110. The air outlet frame 130 includes a connecting outer frame 131 with a passage opening 134 formed in the middle, a first baffle plate 132 connected to the right end of the connecting outer frame 131 and extending to the passage opening 134 and connected to the air duct component 200, and a second baffle plate 133 connected to the left end of the connecting outer frame 131 and extending to the passage opening 134 and connected to the air duct component 200. The air outlet cavity 300 is located between the air outlet grille 110, the first baffle plate 132 and the second baffle plate 133.

[0143] Reference Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18In this embodiment, an air inlet cavity 500 is formed between the rear side of the first wind deflector 132, the second wind deflector 133 and the air duct component 200 and the air inlet grille 120. The first wind deflector 132 and the second wind deflector 133 are used to separate and relatively seal the two cavities of the air outlet cavity 300 and the air inlet cavity 500, so that the airflow entering the air inlet cavity 500 from the air inlet grille 120 can only enter the air outlet cavity 300 through the air supply duct 210.

[0144] Reference Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, the air duct component 200 includes a volute 220 and a volute tongue 230 connected to each other, an air supply duct 210 is formed between the volute 220 and the volute tongue 230, a first baffle plate 132 is connected to the volute tongue 230, and a second baffle plate 133 is connected to the volute 220.

[0145] Reference Figure 2 , Figure 7 , Figure 12 , Figure 17 or Figure 18 In this embodiment, the cross-section of the air inlet grille 120 is semi-circular to ensure the air intake volume or air intake efficiency of the vertical air conditioner indoor unit.

[0147] Furthermore, the number of oscillating blades 600 can be set horizontally to one or more. And it can be configured according to the case of the guide plate, air guide plate 410, or air-guiding component 460 provided at the air outlet 1111, to ensure that the airflow entering the air outlet cavity 300 from the air supply duct 210 can be guided by the air guiding mechanism 400 to the ventilation section 111 that is pre-passed through in the aforementioned embodiments and flows out of the housing 100 according to the preset direction in the aforementioned embodiments. For example, when the air guiding mechanism 400 is an air guide plate 410, the number of oscillating blades 600 can be set to three; when the air guiding mechanism 400 is a left guide plate 420 and a right guide plate 430, the number of oscillating blades 600 can be set to two; when the air guiding mechanism 400 is a left guide plate 420, a middle guide plate 440, and a right guide plate 430, the number of oscillating blades 600 can be set to one; when the air guiding mechanism 400 includes an air-guiding component 460 provided at the air outlet 1111, the number of oscillating blades 600 can be set to one.
