Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and in particular to a vertical air conditioner indoor unit. Background Art

[0002] With the development of the air-conditioning industry, users have higher and higher requirements for the air supply experience of air conditioners. In a vertical air-conditioning indoor unit, the casing air outlet is usually opened on the front side of the casing and extends along the height direction of the casing. The casing air outlet is long and narrow and has a large overlap range with the height of the human body. The vertical air-conditioning indoor unit is easy to blow directly on the human body during cooling, causing discomfort to the human body. Although in the prior art, swing blades are usually set at the casing air outlet, on the one hand, the swing blades guide the airflow, change the angle of the airflow out of the casing air outlet, and avoid blowing directly on the human body, on the other hand, the swing blades can break up the airflow flowing out of the casing air outlet, thereby reducing the direct blowing effect of the airflow on the human body. Although setting a swing blade at the casing air outlet can reduce the direct blowing effect of the airflow on the human body, it will also weaken the air outlet effect of the air conditioner and reduce the air outlet volume of the air conditioner.

[0003] Therefore, the vertical air-conditioning indoor unit in the prior art cannot well meet the user's air supply experience requirements. Utility Model Content

[0065] The vertical air-conditioning indoor unit provided in the embodiment of the present application may have various implementation forms. The vertical air-conditioning indoor unit may be a vertical air-conditioning indoor unit with a fresh air function, a vertical air-conditioning indoor unit with a dehumidification function, or a traditional vertical air-conditioning indoor unit.

[0066] Figure 1-Figure 14 This is a specific implementation of the vertical air-conditioning indoor unit of the present application.

[0067] The direction described in the article is based on the direction in which the user is facing the air-conditioning indoor unit, wherein the left and right sides are distinguished by the direction in which the user is facing the air-conditioning indoor unit, the side facing the user when the air-conditioning indoor unit is in use is defined as the front side, and the opposite side is defined as the rear side, and the upper and lower sides of the air-conditioning indoor unit when it is generally working normally are defined to distinguish up and down.

[0068] The vertical air conditioner indoor unit includes a casing, which is used to form the overall appearance of the air conditioner indoor unit. The height direction of the casing is from the top to the bottom of the casing, the width direction is from the left side to the right side of the casing, and the thickness direction is from the front side to the back side of the casing.

[0069] The casing comprises a casing air inlet, and the casing air inlet is arranged at the rear side of the casing and / or the left and right sides of the casing.

[0070] The casing comprises a casing air outlet, which is arranged at the front side of the casing and extends along the height direction of the casing.

[0071] The vertical air conditioner indoor unit comprises a heat exchanger, which is arranged in a casing. The heat exchanger is arranged close to an air inlet of the casing and is used for exchanging heat for air passing through the heat exchanger.

[0072] The vertical air conditioner indoor unit includes a fan, which is installed in the casing to promote air flow and increase the heat exchange effect of the heat exchanger. The indoor air is introduced into the casing from the casing air inlet through the operation of the fan, and after heat exchange treatment by the heat exchanger, it forms conditioned air, which is discharged into the room from the casing outlet to meet the user's cooling or heating needs.

[0073] It should be noted that the air-conditioning wind can be cold air, hot air, or normal temperature air.

[0074] In a vertical air conditioner indoor unit, the fan is a cross-flow fan, and the fan is arranged along the height direction of the casing. The fan is usually installed in a volute 100.

[0075] like Figure 1As shown, the volute 100 includes a volute air inlet 101 , so that the air entering the casing through the casing air inlet enters the volute 100 through the volute air inlet 101 .

[0076] The volute 100 includes a volute air outlet, which is connected to the casing air outlet. The air in the volute 100 is output to the room through the volute air outlet and the casing air outlet.

[0077] Through the operation of the fan, air enters the casing from the casing air inlet and exchanges heat with the heat exchanger to form conditioned air. The conditioned air enters the volute 100 from the volute air inlet 101 and then flows from the volute air outlet through the casing air outlet to the room.

[0078] In some embodiments, the volute air outlet and the casing air outlet are interconnected and arranged correspondingly.

[0079] It should be noted that the volute 100 is arranged along the height direction of the casing, the top of the volute 100 is arranged corresponding to the top of the casing, the bottom of the volute 100 is arranged corresponding to the bottom of the casing, the left side of the volute 100 is arranged corresponding to the left side of the casing, the right side of the volute 100 is arranged corresponding to the right side of the casing, the front side of the volute 100 is arranged corresponding to the front side of the casing, and the rear side of the volute 100 is arranged corresponding to the rear side of the casing. The height direction of the volute 100 is arranged in the same direction as the height direction of the casing.

[0080] like Figure 1-Figure 3 As shown, the vertical air conditioner indoor unit includes a swing blade, which is rotatably arranged at the air outlet of the casing to guide the air flow.

[0081] The number of swing blades is usually multiple, and the plurality of swing blades are distributed along the height direction of the casing.

[0082] like Figure 1-Figure 3 As shown, the vertical air conditioner indoor unit includes a connecting rod 200, which is arranged at the air outlet of the casing and is arranged along the height direction of the casing; the swing blade is connected to the connecting rod 200, and the connecting rod 200 is used to drive multiple swing blades arranged at the air outlet of the casing to rotate simultaneously.

[0083] like Figure 3-Figure 6 As shown, the vertical air-conditioning indoor unit includes a driving motor 500, which is installed in the casing; the driving motor 500 is used to drive the connecting rod 200 to move linearly along the height direction of the casing.

[0084] When the driving motor 500 drives the connecting rod 200 to perform linear motion along the height direction of the casing, the connecting rod 200 drives the plurality of swing blades disposed at the air outlet of the casing to rotate.

[0085] like Figure 6As shown, the output shaft of the driving motor 500 is connected to a force transmission rod 510, and one end of the force transmission rod 510 away from the output shaft is connected to the connecting rod 200. The force transmission rod 510, the connecting rod 200 and the swing blade together define a four-bar 200 mechanism.

[0086] It should be noted that, in some embodiments, the force transfer rod 510, the connecting rod 200 and the swing blade together define a crank slider mechanism; in other embodiments, the force transfer rod 510, the connecting rod 200 and the swing blade together define a double rocker mechanism.

[0087] In this embodiment, the driving motor 500 is installed on the top of the housing, and the force transmission rod 510 is connected to the top end of the connecting rod 200 .

[0088] Although the swing blades can change the flow direction of the airflow when it is output from the air outlet of the casing to the room to prevent the airflow from blowing directly on the human body, the airflow is guided in the same direction by different swing blades, that is, the airflow is output to the room in the same direction. In the direction of the airflow output, the airflow velocity and flow rate are large, which will also blow directly on the human body, causing discomfort to the user. In the vertical air conditioner indoor unit, the air outlet of the casing is arranged along the height direction of the casing, and at least part of the air outlet of the casing coincides with the human height range of the user. Even if the airflow direction is changed to make the airflow blow upward, part of the airflow will still blow on the human body.

[0089] Based on this, in this application, Figure 5 As shown, two kinds of swing blades are arranged at the air outlet of the casing, and the two kinds of swing blades guide the airflow in different directions to prevent the airflow from directly blowing on the human body.

[0090] Specifically, the vertical air-conditioning indoor unit includes an upper swing blade 300 , and the upper swing blade 300 is connected to the connecting rod 200 , so that the connecting rod 200 drives the upper swing blade 300 to rotate.

[0091] The upper swing leaf 300 is rotatably connected to the casing so that the casing constrains the upper swing leaf 300 , and when the connecting rod 200 performs a linear motion along the height direction of the casing, the upper swing leaf 300 rotates.

[0092] The upper swing blade 300 and the casing together define a first rotation axis. The upper swing blade 300 rotates relative to the casing along the first rotation axis, and the first rotation axis intersects with the height direction of the casing.

[0093] The vertical air conditioner indoor unit includes a lower swing blade 400, and the lower swing blade 400 is connected to the connecting rod 200, so that the connecting rod 200 drives the lower swing blade 400 to move.

[0094] The lower swing leaf 400 is rotatably connected to the casing, so that the casing constrains the lower swing leaf 400, so that the connecting rod 200 moves linearly along the height direction of the casing, and the lower swing leaf 400 rotates.

[0095] The lower swing leaf 400 and the casing together define a second rotation axis. The lower swing leaf 400 rotates relative to the casing along the second rotation axis, and the second rotation axis intersects with the height direction of the casing.

[0096] The second rotating shaft is arranged in parallel with the first rotating shaft, so that the connecting rod 200 drives the upper swing leaf 300 and the lower swing leaf 400 to rotate simultaneously.

[0097] It should be noted that the lower swing leaf 400 is slidably connected to the connecting rod 200 so that the connecting rod 200 can simultaneously drive the upper swing leaf 300 and the lower swing leaf 400 to rotate to prevent over-constraint.

[0098] According to the air outlet direction defined by the upper swing blade 300 and the air outlet direction defined by the lower swing blade 400, the air outlet of the casing can be divided into two parts for convenience of description.

[0099] Specifically, the air outlet of the casing includes a first air outlet portion, the first air outlet portion is distributed along the height direction of the casing, and the first air outlet portion is arranged close to the top of the casing; the upper swing blade 300 is arranged at the first air outlet portion.

[0100] The air outlet of the casing includes a second air outlet portion, the second air outlet portion is distributed along the height direction of the casing, and the second air outlet portion is arranged close to the bottom of the casing; the lower swing leaf 400 is arranged at the second air outlet portion.

[0101] The distance between the lower swing blade 400 and the axis of the fan is less than or equal to the distance between the upper swing blade 300 and the axis of the fan, so that the lower swing blade 400 is arranged closer to the interior of the casing than the upper swing blade 300, so that the lower swing blade 400 guides the airflow toward the first air outlet, so that at least the airflow is output from the first air outlet to the room, thereby reducing the amount of air output by the second air outlet, and reducing the direct blowing effect of the airflow output by the second air outlet on the human body.

[0102] like Figure 7 As shown, the connecting rod 200 includes a first section 210 , which is disposed close to the top of the housing, and the upper swing leaf 300 is rotatably connected to the first section 210 .

[0103] The connecting rod 200 includes a second section 220 , which is disposed close to the bottom of the housing, and the lower swing leaf 400 is connected to the second section 220 .

[0104] The second section 220 is provided with an extension portion 221 , and the extension portion 221 is provided with a slideway 222 for guiding the lower swing leaf 400 to slide, and the slideway 222 is extended from the outside of the casing toward the inside of the casing.

[0105] The second section 220 is arranged closer to the interior of the casing than the first section 210, so that the lower swing leaf 400 is arranged closer to the interior of the casing than the upper swing leaf 300, so that the lower swing leaf 400 guides the airflow to the first air outlet, so that the airflow is mainly output to the room by the first air outlet, thereby reducing the direct blowing effect of the airflow from the second air outlet on the human body.

[0106] In some embodiments, the first section 210 and the second section 220 extend along the height direction of the housing respectively; the connecting rod 200 includes a transition section 230 , and the transition section 230 is used to connect the first section 210 and the second section 220 .

[0107] In practical applications, a plurality of upper swing blades 300 are provided, and the plurality of upper swing blades 300 are distributed at the first air outlet portion along the height direction of the casing.

[0108] The surface of the upper swing blade 300 is defined to form a first wind guide surface, and the first wind guide surface is used to guide the air flow. The first wind guide surface is located on the opposite side of two adjacent upper swing blades 300.

[0109] like Figure 8-Figure 10 As shown, a horizontal plane passing through the axis of the first rotation axis is defined as a first plane 301 .

[0110] The first wind guiding surface and the first plane 301 together define a first angle α, and the first angle α satisfies: α≥0°, α<90°.

[0111] It should be noted that, in the present embodiment, the first air guide surface is a plane, and in practical applications, the first air guide surface may also be a curved surface.

[0112] It should also be explained that, since the side of the upper swing blade 300 facing the top of the casing and the side facing the bottom of the casing are in contact with the airflow respectively, the side of the upper swing blade 300 facing the top of the casing and the side facing the bottom of the casing are both first air guide surfaces. When the side of the upper swing blade 300 facing the top of the casing and the side facing the bottom of the casing are parallel to each other, the first angle α defined by the side of the upper swing blade 300 facing the top of the casing and the first plane 301 is the same as the first angle α defined by the side of the upper swing blade 300 facing the bottom of the casing and the first plane 301; when the side of the upper swing blade 300 facing the top of the casing and the side facing the bottom of the casing intersect, since the thickness of the upper swing blade 300 is relatively small, the difference between the first angle α defined by the side of the upper swing blade 300 facing the top of the casing and the first plane 301 and the first angle α defined by the side of the upper swing blade 300 facing the bottom of the casing and the first plane 301 is relatively small and can be ignored. This is common knowledge in the field and will not be elaborated on.

[0113] In practical applications, a plurality of lower blades 400 are provided, and the plurality of lower blades 400 are distributed at the air outlet of the casing along the height direction of the casing.

[0114] The surface of the lower swing leaf 400 is defined to form a second wind guide surface, and the second wind guide surface is used to guide the air flow. The second wind guide surface is located on the opposite side of two adjacent lower swing leaves 400.

[0115] like Figure 8-Figure 10 As shown, a horizontal plane passing through the axis of the second rotation axis is defined as the second plane 401 .

[0116] The second wind guiding surface and the second plane 401 together define a second angle β, and the second angle β satisfies: β≥0°, β<90°.

[0117] It should also be explained that, since the side of the lower leaf 400 facing the top of the casing and the side facing the bottom of the casing are in contact with the airflow respectively, the side of the lower leaf 400 facing the top of the casing and the side facing the bottom of the casing are both first air guide surfaces. When the side of the lower leaf 400 facing the top of the casing and the side facing the bottom of the casing are parallel to each other, the second angle β formed by the side of the lower leaf 400 facing the top of the casing and the second plane 401 is the same as the second angle β formed by the side of the lower leaf 400 facing the bottom of the casing and the second plane 401; when the side of the lower leaf 400 facing the top of the casing and the side facing the bottom of the casing intersect, since the thickness of the lower leaf 400 is relatively small, the difference between the second angle β formed by the side of the lower leaf 400 facing the top of the casing and the second plane 401 and the second angle β formed by the side of the lower leaf 400 facing the bottom of the casing and the second plane 401 is relatively small and can be ignored. This is common knowledge in the field and will not be elaborated on.

[0118] The second angle β and the first angle α satisfy the relationship: α≤β, so that the outlet angles of the first air outlet and the second air outlet are different, so that the airflow from the air outlet of the casing to the room can flow in different directions.

[0119] Since the second air outlet has a greater direct blowing effect on the human body than the first air outlet, in the present application, the second air outlet can be opened or closed according to user needs to prevent the air flow from directly blowing on the human body; in order to ensure the air outlet effect and air volume of the air-conditioning indoor unit, the first air outlet is used as the main air outlet for the air flow to avoid closing the first air outlet and the second air outlet or reducing their openings to affect the air volume.

[0120] When the connecting rod 200 moves the same distance, the rotation angle △α of the upper swing leaf 300 and the rotation angle △β of the lower swing leaf 400 satisfy the relationship: △α<△β, so that the angle change amplitude of the upper swing leaf 300 is smaller than the angle change amplitude of the lower swing leaf 400.

[0121] like Figure 8 As shown, when the connecting rod 200 moves to the first position, the upper swing leaf 300 opens the first air outlet, and the lower swing leaf 400 closes the second air outlet, and the angle α and the angle β satisfy the relationship: α<β.

[0122] It should be noted that when the connecting rod 200 moves to the first position, the connecting rod 200 is at a dead point position. When the connecting rod 200 is at the dead point position, the lower swing leaf 400 closes the second air outlet.

[0123] When the connecting rod 200 moves from the first position to the second position, the rotation angle △α of the upper swing leaf 300 and the rotation angle △β of the lower swing leaf 400 satisfy the relationship: △α<△β.

[0124] The distance between the connection point between the first wind guide surface and the connecting rod 200 and the first rotation axis is d.

[0125] The distance D between the connection point between the second air guide surface and the connecting rod 200 and the second rotation axis.

[0126] d, D and the first angle α and the second angle β satisfy the relationship: d×sinα=D×sinβ.

[0127] like Fig.11 and Fig.12 As shown, the upper swing blade 300 is provided with a first rotating part 310, which is located at one end of the upper swing blade 300 arranged along the first rotation axis, and the first rotating part 310 is rotatably connected to the housing. The first rotation axis is defined by the first rotating part 310 and the housing.

[0128] The upper swing leaf 300 is provided with a first connection portion 320, which is located on a side of the upper swing leaf 300 away from the inside of the housing, and the first connection portion 320 is rotatably connected to the connecting rod 200. The first connection portion 320 and the connecting rod 200 define a rotation axis together, and the upper swing leaf 300 rotates relative to the connecting rod 200 around the rotation axis.

[0129] The upper swing leaf 300 is provided with a first avoidance portion 330, which is used to prevent the connecting rod 200 from interfering with the movement of the upper swing leaf 300; the first avoidance portion 330 is provided on a side of the upper swing leaf 300 away from the interior of the casing, and the first avoidance portion 330 extends toward the interior of the casing.

[0130] It should be noted that, in some embodiments, the first avoidance portion 330 is a notch opening toward the outside of the housing.

[0131] In some other embodiments, the first connecting portion 320 is located at an inner edge of one side of the first avoiding portion 330 .

[0132] The first rotating axis and the rotation axis jointly define a connecting line, which is located in the first wind guiding surface, and a plane passing through the connecting line jointly defined by the first rotating axis and the rotation axis and extending in the horizontal direction coincides with the first wind guiding surface.

[0133] like Fig.13 and Fig.14As shown, the lower swing leaf 400 is provided with a second rotating part 410, which is located at one end of the lower swing leaf 400 arranged along the second rotation axis, and the second rotating part 410 is rotatably connected to the housing. The second rotation axis is defined by the second rotating part 410 and the housing.

[0134] The lower swing leaf 400 is provided with a second avoidance portion 430, which is used to prevent the connecting rod 200 from interfering with the movement of the lower swing leaf 400; the second avoidance portion 430 is provided on a side of the lower swing leaf 400 away from the interior of the casing, and the second avoidance portion 430 extends toward the interior of the casing.

[0135] The lower swing leaf 400 is provided with a second connection portion 420 . The second connection portion 420 is provided at an inner edge of one side of the second avoidance portion 430 . The second connection portion 420 is provided in the slideway 222 and slides along the slideway 222 .

[0136] The lower swing blade 400 includes a first swing blade 460 , and the second rotating portion 410 is disposed on the first swing blade 460 .

[0137] The lower swing blade 400 includes a second swing blade 440, which is connected to the first swing blade 460 and is located on the side of the first swing blade 460 facing the bottom of the housing. The second avoidance portion 430 is arranged to penetrate the second swing blade 440 along its extension direction; and the second connection portion 420 is connected to the second swing blade 440.

[0138] There is a gap between the second swing blade 440 and the first swing blade 460 along the height direction of the casing, so that the first swing blade 460 and the second swing blade 440 together define a ventilation portion 450, and the ventilation portion 450 is used to connect the side of the lower swing blade 400 facing the top of the casing and the side of the lower swing blade 400 facing the bottom of the casing.

[0139] like Figure 8-Figure 10 As shown, the connection between the second rotation axis, the lower swing leaf 400 and the connecting rod 200 jointly defines a connection line 402.

[0140] A plane extending in the horizontal direction through the connecting line 402 is defined as a third plane. The third plane and the second plane 401 together define a third angle γ. The third angle γ and the second angle β satisfy the relationship: γ≤β.

[0141] The length of the line defined by the first rotation axis and the rotation axis is L1.

[0142] The length of the connection line 402 is L2.

[0143] L1 and L2 satisfy the relationship: L1×tanα=L2×cos(β-γ)×tanβ.

[0144] like Figure 8As shown, the first section 210 defines a first center line 201 along the height direction of the housing.

[0145] The second section 220 defines a second center line 202 along the height direction of the housing.

[0146] The distance between the second center line 202 and the first center line 201 along the horizontal direction is L3.

[0147] L3 satisfies the relationship: L3>9mm, L3<20mm, so as to ensure that the swing angle of the upper swing leaf 300 and the swing angle of the lower swing leaf 400 can support the function of preventing direct blowing.

[0148] When the second angle β and the third angle γ satisfy the relationship: β≥1 / 2γ, the slideway length L satisfies the relationship: L=L1×tanα-L2×-tanβ.

[0149] It should be noted that in order to ensure that the lower leaf 400 can slide freely in the slide without getting stuck, the final length of L needs to be multiplied by a safety factor of 1.2-1.5 based on the calculated L.

[0150] In some embodiments, the width of the upper swing blade 300 is smaller than that of the lower swing blade 400. By making the overall width of the swing blade gradually increase downward along the height direction of the casing, the wind guiding effect of the lower swing blade 400 is made stronger than the wind guiding effect of the upper swing blade 300. Through the pressure loss gradient along the way, the cold air from the second air outlet is guided to the first air outlet and blown out together with the air from the first air outlet, which is beneficial to the cooling of the cold air from top to bottom, thereby increasing the effect of preventing direct blowing of the second air outlet of the air conditioner indoor unit.

[0151] The working principle of the upper swing leaf 300 and the lower swing leaf 400 will be described in detail below by taking the case where the connecting rod 200 is at the dead point and the first angle α is 37° as an example.

[0152] When the indoor unit of the floor-standing air conditioner is turned on, Figure 1 and Figure 5 As shown, the connecting rod 200 is in the first position, the upper swing leaf 300 and the lower swing leaf 400 are respectively arranged in the horizontal direction, at this time, the first angle α=0°, the second angle β=0°, the resistance of the upper swing leaf 300 to the airflow is the same as the resistance of the lower swing leaf 400 to the airflow, the airflow output from the air outlet of the casing to the room is blown out in the horizontal direction, and the air output of the first air outlet and the second air outlet is consistent.

[0153] like Figure 3As shown, when the driving motor 500 drives the connecting rod 200 to drive the connecting rod 200 to move upward in a straight line, the upper swing leaf 300 and the lower swing leaf 400 respectively rotate upward in the clockwise direction. When the first angle α of the rotation angle is less than 37°, the second angle β is 37° less than β less than 90°, the upper swing leaf 300 and the lower swing leaf 400 are not closed, and both the first air outlet and the second air outlet can discharge air. Among them, the wind resistance of the lower swing leaf 400 is large, and at least part of the airflow that should have been output from the second air outlet to the room is guided to the first air outlet by the lower swing leaf 400, and output to the room by the first air outlet. Therefore, the air volume of the first air outlet is large and the wind speed is high, while the air volume output to the room by the second air outlet is reduced, thereby weakening the direct blowing effect of the second air outlet on the human body, and reducing the blowing feeling of the airflow output from the second air outlet on the human body.

[0154] like Figure 4 As shown, when the driving motor 500 drives the connecting rod 200 to continue to move linearly upward to the dead point position of the connecting rod 200, the connecting rod 200 is in the second position. At this time, α=37°, β=90°, and the lower swing leaf 400 closes the second air outlet to prevent the airflow from being output from the second air outlet to the room. The air volume is guided from the first air outlet through the upper swing leaf 300 to the room. At this time, the second air outlet can prevent direct blowing.

[0155] When the connecting rod 200 moves from the first position to the second position, the first angle α changes from 0° to 37°, that is, the rotation angle of the upper swing leaf is 37°, and the second angle β changes from 0° to 90°, that is, the rotation angle of the lower swing leaf 400 is 90°.

[0156] The vertical air conditioner indoor unit is provided with an upper swing blade 300 and a lower swing blade 400 at the air outlet of the casing, and the first angle α is less than or equal to the second angle β, so that the upper swing blade 300 and the lower swing blade 400 guide the airflow in different directions respectively. The upper swing blade 300 and the lower swing blade 400 are driven to rotate simultaneously by the connecting rod 200, so as to simplify the overall structure and facilitate the layout.

[0157] When it is necessary to reduce the blowing feeling of the second air outlet on the human body, the connecting rod 200 drives the lower leaf 400 to rotate upward clockwise, so that the lower leaf 400 is tilted upward to guide the airflow output by the second air outlet to blow upward, and the lower leaf 300 is also tilted upward, and the airflow output by the first air outlet is also blown upward, so that the cold air is cooled from top to bottom, increasing the cooling effect of the air conditioner indoor unit.

[0158] When the lower swing leaf 400 is needed to close the second air outlet to prevent the airflow output from the second air outlet from directly blowing on the human body, at this time, the upper swing leaf 300 still opens the first air outlet to allow the airflow inside the casing to be output from the first air outlet to the room, so as to ensure the air outlet effect of the air conditioner indoor unit and avoid reducing the air outlet effect of the air conditioner indoor unit due to the closure of the casing air outlet.
