Description

Technical Field

[0045] Figure 5 is a cross-sectional view of an indoor unit of a vertical air conditioner according to still another embodiment of the present invention. Detailed Description of the Embodiment

[0046] This embodiment provides an indoor unit of a vertical air conditioner. By providing double-layer vertical swing blades, the swing effect of the air can be improved, and while effectively improving the overall energy efficiency, the user experience can be enhanced. Figure 1 is a front view of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention, Figure 2 is a side view of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention, Figure 3 is a cross-sectional view of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention. As Figures 1 to 3 shown, the indoor unit 100 of the vertical air conditioner in this embodiment generally may include: a housing 110, a first vertical swing blade 161, and a second vertical swing blade 162.

[0047] Among them, an air outlet 117 may be formed in the front part of the housing 110. The first vertical swing blade 161 and the second vertical swing blade 162 are respectively disposed at the left end and the right end of the air outlet 117. And, the first vertical swing blade 161 and the second vertical swing blade 162 are arranged staggered front and back. By providing double-layer vertical swing blades, the swing effect of the air can be improved, and while effectively improving the overall energy efficiency, the user experience can be enhanced.

[0048] Specifically, the housing 110 may include a front door panel 112, a front scroll tongue 114, and a rear scroll tongue 113. One end of the front scroll tongue 114 and one end of the rear scroll tongue 113 are both connected to the front door panel 112, and an air outlet 117 is formed between the front scroll tongue 114 and the rear scroll tongue 113. In a preferred embodiment, the left end of the first vertical swing blade 161 is connected to the front scroll tongue 114, and the first vertical swing blade 161 rotates about its left end as the rotation axis; the right end of the second vertical swing blade 162 is connected to the rear scroll tongue 113, and the second vertical swing blade 162 rotates about its right end as the rotation axis. Also, the first vertical swing blade 161 is located behind the second vertical swing blade 162.

[0049] Compared with the traditional vertical swing blade that rotates about the center as the rotation axis, in this embodiment, the first vertical swing blade 161 rotates about its left end as the rotation axis; the second vertical swing blade 162 rotates about its right end as the rotation axis, which can effectively solve the problem of air outlet deviation of the fan. Especially for the current indoor unit of the vertical air conditioner, a conventional single-layer vertical swing blade is often set. Affected by the rotation angle, the air swing effect to the right is poor. By setting the double-layer vertical swing blade in this embodiment, the air swing effect can be improved, effectively improving the overall energy efficiency while enhancing the user experience.

[0050] In a preferred embodiment, the indoor unit 100 of the vertical air conditioner may further include: a first motor and a second motor (both not shown in the figure). Among them, the first motor is connected to the first vertical swing blade 161 and is configured to control the rotation angle of the first vertical swing blade 161. The second motor is connected to the second vertical swing blade 162 and is configured to control the rotation angle of the second vertical swing blade 162. That is to say, the first vertical swing blade 161 and the second vertical swing blade 162 are separately controlled by the first motor and the second motor, respectively, and can achieve different rotation angles, so as to be able to expand a variety of air outlet forms and fully meet the user's usage requirements.

[0051] Specifically, as Figure 3 shown, when the rotation angle of the first vertical swing blade 161 is the first angle and the rotation angle of the second vertical swing blade 162 is the second angle, a difference in wind feeling is achieved. Figure 4 is a cross-sectional schematic view of the indoor unit 100 of the vertical air conditioner according to another embodiment of the present invention. As Figure 4 shown, when the rotation angle of the first vertical swing blade 161 is the third angle and the rotation angle of the second vertical swing blade 162 is the fourth angle, parallel soft wind is achieved.

[0052] Figure 5 is a cross-sectional schematic view of the indoor unit 100 of the vertical air conditioner according to still another embodiment of the present invention. As Figure 5 shown, when the rotation angle of the first vertical swing blade 161 is the fifth angle and the rotation angle of the second vertical swing blade 162 is the sixth angle, wide-angle air outlet is achieved. Specifically, Figure 5It realizes wide-angle air outlet at the right end, which can effectively solve the problem of left-biased air outlet of traditional fans. It should be noted that the rotation angle of the first vertical swing blade 161 can refer to the included angle between the first vertical swing blade 161 and the side wall of the front scroll tongue 114 at the left end. The rotation angle of the second vertical swing blade 162 can refer to the included angle between the second vertical swing blade 162 and the side wall of the rear scroll tongue 113 at the right end.

[0053] In a preferred embodiment, the indoor unit 100 of the vertical air conditioner may further include: a first horizontal swing blade 171 and a second horizontal swing blade 172. Among them, the left end of the first horizontal swing blade 171 is connected to the front scroll tongue 114. The right end of the second horizontal swing blade 172 is connected to the rear scroll tongue 113. And the first horizontal swing blade 171 and the second horizontal swing blade 172 are arranged staggered in the front and rear directions. The indoor unit of the vertical air conditioner may further include: a third motor and a fourth motor (both not shown in the figure). Among them, the third motor is connected to the first horizontal swing blade 171 and is configured to control the rotation angle of the first horizontal swing blade 171. The fourth motor is connected to the second horizontal swing blade 172 and is configured to control the rotation angle of the second horizontal swing blade 172.

[0054] That is to say, the first horizontal swing blade 171 and the second horizontal swing blade 172 are also separately controlled by the third motor and the fourth motor respectively, and can achieve different rotation angles, so that more air outlet forms can be further expanded in combination with the different rotation angles of the first vertical swing blade 161 and the second vertical swing blade 162. As Figures 3 to 5 shown, the first horizontal swing blade 171, the second vertical swing blade 162, the first vertical swing blade 161, and the second horizontal swing blade 172 are arranged in sequence from front to back. By the staggered arrangement of the first horizontal swing blade 171, the second vertical swing blade 162, the first vertical swing blade 161, and the second horizontal swing blade 172, an interference effect can be generated on the air outlet airflow, so as to realize various air outlet forms with different body sensations. And the first horizontal swing blade 171 and the second horizontal swing blade 172 in this embodiment can achieve a large-span up-and-down swing effect. Specifically, an up-and-down 160° swing effect can be achieved.

[0055] The interior of the housing 110 may define a cavity 111. The vertical air conditioner indoor unit 100 further includes: a heat exchanger 120. The heat exchanger 120 may be disposed in the cavity 111 and configured to exchange heat with the air entering the cavity 111. One end of the heat exchanger 120 is located at the rear side of the rear scroll tongue 113, which may cause the air volume at one end of the heat exchanger 120 located at the rear side of the rear scroll tongue 113 to be blocked by the rear scroll tongue 113, resulting in air volume loss. Therefore, the vertical air conditioner indoor unit 100 may further include: an air supply compensation structure 132. The air supply compensation structure 132 may be disposed at the rear side of the heat exchanger 120 and close to one end of the heat exchanger 120 located at the rear side of the rear scroll tongue 113, and is configured to compensate for the air volume blocked by the rear scroll tongue 113 here. The air supply compensation structure 132 can solve the problem that part of the air volume of the heat exchanger 120 is blocked by the rear scroll tongue 113, and can further increase the air volume and strongly boost the pressure.

[0056] In a specific embodiment, the vertical air conditioner indoor unit 100 may further include: a supply air fan 130, which is disposed in the cavity 111 and in front of the heat exchanger 120. Through the supply air fan 130, the air heated by the heat exchanger 120 can be sent to the indoor environment. The common types of fans that can generally be used in the air conditioner indoor unit mainly include: centrifugal fans, cross-flow fans, and axial fans.

[0057] Among them, the air inside the centrifugal fan is affected by the centrifugal force, generating a vacuum degree in the center of the impeller. After the inhaled air turns 90° at the impeller inlet, it enters the flow channel formed by the blades and obtains kinetic energy and pressure energy under the action of the blades. The air flow discharged from the blade channel enters the volute, and after being concentrated and guided, it is discharged from the outlet of the centrifugal fan.

[0058] The cross-flow fan can also be called a transverse flow fan. The air flow radially enters the blade grid from the open part of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid to form a working air flow. The air flow in the axial fan flows axially inside the impeller. Each of the above three types of fans has its own advantages and disadvantages and can be set according to the actual situation. In this embodiment, the supply air fan 130 and the air supply compensation structure 132 can both be cross-flow fans or centrifugal fans. Preferably, both the supply air fan 130 and the air supply compensation structure 132 can be cross-flow fans.

[0059] The supply air fan 130 may also be correspondingly provided with a motor (not shown in the figure), configured to drive the supply air fan 130 to rotate. And the air supply speed of the vertical air conditioner indoor unit 100 can be adjusted by adjusting the rotation speed of the motor driving the supply air fan 130. Similarly, the air supply compensation structure 132 may also be correspondingly provided with a motor, configured to drive the air supply compensation structure 132 to rotate.

[0060] In this embodiment, both the air supply fan 130 and the air make-up structure 132 can be cross-flow fans. This is because the axial length of the cross-flow fan is not restricted, and the length of the impeller can be arbitrarily selected according to different usage requirements. Moreover, the air flow passes through the impeller, and is affected by the blades twice, so the air flow can reach a long distance and the air supply is relatively far. In addition, the cross-flow fan has no turbulent flow, the air outlet is uniform, and the noise is low, which can effectively improve the user experience.

[0061] The following problems are likely to occur when only a single air supply fan is provided in a traditional vertical air conditioner indoor unit: The cross-flow fan has an inherent problem of wind speed difference, which will cause the wind speed of the vertical air conditioner indoor unit to gradually decrease slowly from the high-wind area on the left to one end of the rear volute tongue on the right. Especially in the area of the rear volute tongue, the wind speed drops exponentially. The low wind speed directly leads to a decrease in the utilization efficiency of the heat exchanger. Due to the wind speed relationship, the heat exchanger on the right cannot exert its optimal performance, affecting the heat exchange effect of the vertical air conditioner indoor unit and unable to fully meet the user's usage requirements. In this embodiment, this problem can be effectively solved by providing the air make-up structure 132. Specifically, the air make-up structure 132 can also be configured to make up for the reduced wind speed at one end of the heat exchanger 120 located behind the rear volute tongue 113 caused by the air supply fan 130.

[0062] That is to say, for the vertical air conditioner indoor unit 100 of this embodiment, by arranging the air make-up structure 132 behind the heat exchanger 120 and near one end of the heat exchanger 120 located behind the rear volute tongue 113, the problems of air volume obstruction and slow wind speed at one end of the rear volute tongue 113 of the vertical air conditioner indoor unit 100 can be solved, effectively improving the overall energy efficiency and the user experience.

[0063] In a preferred embodiment, the housing 110 can further include: an air inlet grille 115, connected to the front door panel 112, and an air inlet 116 is provided on the air inlet grille 115, configured to allow the air in the indoor environment to enter the cavity 111 through the air inlet 116. In fact, the housing 110 can include a front door panel 112 and a rear panel 119, and the air inlet grille 115 can be provided on the rear panel 119. A filter screen can be provided at the air inlet 116 of the air inlet grille 115, so as to be able to preliminarily filter the air entering the cavity 111 through the air inlet 116, improving the cleanliness of the interior of the vertical air conditioner indoor unit 100 and the finally discharged air. The air outlet 117 formed between the front volute tongue 114 and the rear volute tongue 113 can also be shown on the front door panel 112.

[0064] In addition, the housing 110 may further include panels such as a top plate and a bottom plate. The arrangement of the top plate and the bottom plate can make the overall integrity of the vertical air conditioner indoor unit 100 better and make the vertical air conditioner indoor unit 100 more stable when installed in an indoor environment. The front door panel 112 and the rear panel 119 of the vertical air conditioner indoor unit 100 in this embodiment can be directly connected without additionally providing side panels. In some other embodiments, the housing 110 may further include side panels, and the side panels may include a left side panel and a right side panel, which are respectively connected to the front door panel 112 and the rear panel 119.

[0065] As mentioned above, the heat exchanger 120 is disposed in the cavity 111 and configured to exchange heat with the air entering the cavity 111. When the vertical air conditioner indoor unit 100 operates in the cooling mode, the air exchanged by the heat exchanger 120 is cold air. After being sent to the indoor environment through the air outlet 117, it can reduce the temperature of the indoor environment and make the user feel cool. When the vertical air conditioner indoor unit 100 operates in the heating mode, the air exchanged by the heat exchanger 120 is hot air. After being sent to the indoor environment through the air outlet 117, it can increase the temperature of the indoor environment and make the user feel warm.

[0066] In a specific embodiment, the vertical air conditioner indoor unit 100 can turn on the cooling mode or the heating mode after receiving the opening trigger signal from the user. More specifically, it can receive the opening trigger signal sent by the user through the display device, voice device, remote control of the vertical air conditioner indoor unit 100 or the mobile terminal bound to the vertical air conditioner indoor unit 100. The mobile terminal can be a portable intelligent device, such as a smart phone, a tablet computer, etc.

[0067] The heat exchanger 120 can be disposed in the cavity 111 near the air inlet 116, and the shape of the heat exchanger 120 can be matched with the air inlet 116, so that the air entering the cavity 111 through the air inlet 116 can be completely exchanged by the heat exchanger 120, improving the heat exchange efficiency of the heat exchanger 120. In a preferred embodiment, the vertical air conditioner indoor unit 100 may further include: a wind expanding structure 160, which is disposed between the air inlet grille 115 and the heat exchanger 120. Moreover, the wind expanding structure 160 is located in the left middle part in front of the air inlet grille 115 and is configured to increase the air inlet area of the heat exchanger 120, thereby further improving the heat exchange efficiency of the heat exchanger 120.

[0068] It should be noted that the floor-standing air conditioner indoor unit 100 in this embodiment, as a type of split air conditioner, can be generally used in places such as homes and offices. The floor-standing air conditioner indoor unit 100 has advantages such as high power and strong wind force compared to the wall-mounted air conditioner indoor unit, and its price starting point is relatively higher. The floor-standing air conditioner indoor unit 100 is usually suitable for indoor environments with a relatively large area. For example, if the living room area is relatively large, it is best to choose the floor-standing air conditioner indoor unit 100 to ensure good refrigeration, heating, and air supply effects.

[0069] However, the body thickness of the existing floor-standing air conditioner indoor units is generally relatively thick, and usually has relatively high requirements for the installation space. The main factors restricting the reduction of the body thickness of the floor-standing air conditioner indoor unit are the heat exchanger 120 and ensuring the air inlet area of the air inlet grille 115. The body thickness of the current floor-standing air conditioner indoor units generally reaches 370 mm or even more.

[0070] Moreover, reducing the body thickness of the current floor-standing air conditioner indoor units often causes a part of the heat exchanger 120 to extend into the front door panel 112, resulting in the air inlet of the part extending into the front door panel 112 being blocked, the utilization efficiency of the heat exchanger 120 being poor, affecting the heat exchange effect of the floor-standing air conditioner indoor unit, and being unable to fully meet the user's usage requirements.

[0071] Specifically, in order to reduce the body thickness of the floor-standing air conditioner indoor unit 100, in this embodiment, the other end of the heat exchanger 120 far from the rear scroll tongue 113 can extend into the front door panel 112, and a air supply device similar to the air supply structure 132 (not shown in the figure) can be provided on the rear side of the heat exchanger 120 and at the other end far from the rear scroll tongue 113. The air supply device can be configured to make up for the air volume blocked by the front door panel 112 at the other end of the heat exchanger 120 far from the rear scroll tongue 113. By setting the air supply device, the problem of the blocked air volume of the part of the heat exchanger 120 extending into the door panel can be effectively solved, the air volume and energy efficiency can be effectively improved, and the user's usage experience can be improved.

[0072] The floor-standing air conditioner indoor unit 100 in this embodiment can effectively reduce the body thickness of the floor-standing air conditioner indoor unit 100 while ensuring the air volume by setting the air supply device. Preferably, the body thickness of the floor-standing air conditioner indoor unit 100 in this embodiment is less than 370 mm, which can improve the overall aesthetic degree of the floor-standing air conditioner indoor unit 100 and reduce the occupied space. The reduction of the body thickness of the floor-standing air conditioner indoor unit 100 can also further expand its installation scenario, making it possible to install in spaces that were previously restricted by the body thickness and unable to be installed.

[0073] In a specific embodiment, the body thickness of the vertical air conditioner indoor unit 100 can be 330 to 340 mm. Preferably, the body thickness of the vertical air conditioner indoor unit 100 can be 331 mm. The body thickness of the vertical air conditioner indoor unit 100 in this embodiment has been greatly reduced compared to the conventional body thickness of 370 mm or even more. It should be noted that the specific values of the above body thickness are only examples and not limitations to the present invention. In some other embodiments, it can also be set to other values according to the actual situation, but all can be less than 370 mm.

[0074] In a specific embodiment, the heat exchanger 120 of the vertical air conditioner indoor unit 100 in this embodiment can be V-shaped and bent backward. And the heat exchanger 120 can include a tube sheet 121 and elbows 122 at both ends of the tube sheet 121. The V-shaped heat exchanger 120 can effectively increase the heat exchange area and improve the heat exchange efficiency. However, at the same time, the V-shaped heat exchanger 120 will make the situation of air intake obstruction in the part of the heat exchanger 120 extending into the front door panel 112 more serious. Therefore, it is very crucial and effective to solve the problem of air volume obstruction in the part of the heat exchanger 120 extending into the door panel by setting an air supply supplement device.

[0075] It should be emphasized that the volume of the air supply supplement structure 132 and the air supply supplement device of the vertical air conditioner indoor unit 100 in this embodiment is relatively small compared to the air supply fan 130. While the air supply fan 130 plays a major air supply role, the air supply supplement structure 132 and the air supply supplement device play an effective supplementary and cooperative role to make up for the air volume obstructed at both ends of the heat exchanger 120. The vertical air conditioner indoor unit 100 in this embodiment realizes air supply through the combined action of the air supply fan 130, the air supply supplement structure 132 and the air supply supplement device, and can effectively improve the air volume. In a specific embodiment, compared with the traditional single-fan air supply, the air volume can be increased by about 40%. At the same time, the energy efficiency ratio APF of the vertical air conditioner indoor unit 100 can also be increased by about 25%.

[0076] In a preferred embodiment, the vertical air conditioner indoor unit may further include: a baffle 140, arranged between the heat exchanger 120 and the air inlet grille 115, configured to fix the heat exchanger 120 and the air inlet grille 115 and play a buffering role. The distance between the air inlet grille and the heat exchanger of the current vertical air conditioner indoor unit is relatively close. If it drops during transportation, there is often a risk that the air inlet grille deforms and touches the heat exchanger. For the vertical air conditioner indoor unit 100 in this embodiment, by arranging the baffle 140 between the heat exchanger 120 and the air inlet grille 115, the transportation impact can be effectively reduced, and it can be avoided that the air inlet grille 115 deforms and collides with the heat exchanger 120 due to transportation drop, ensuring the working reliability of the vertical air conditioner indoor unit 100 and improving the user experience.

[0077] The air inlet grille of the existing vertical air conditioner indoor unit generally has separate components such as a filter screen track, resulting in a large number of components, many installation overlapping surfaces, and it is difficult to effectively control the volume problem caused by thermal expansion and contraction. However, the vertical air conditioner indoor unit 100 of this embodiment can well solve the above problems through a unique structural setting. In a specific embodiment, as Figure 3 shown, the air inlet grille 115 may include a body portion 151 and support portions 152 on the left and right sides of the body portion 151. That is to say, the body portion 151 and the support portions 152 on the left and right sides of the body portion 151 are integrally formed as the air inlet grille 115, realizing the integration of the air inlet grille 115, reducing the number of components and optimizing the structure.

[0078] In a preferred embodiment, the body portion 151 and the support portions 152 on the left and right sides of the body portion 151 may both be made of plastic, that is, the entire air inlet grille 115 is made of plastic. Compared with the traditional air inlet grille with two sheet metal columns on the left and right for column support, the body portion 151 and the support portions 152 on the left and right sides of the body portion 151 in this embodiment are made of the same plastic material, which is convenient for realizing the integration of the air inlet grille 115 and taking into account the support strength at the same time.

[0079] In addition, the baffle 140 may have a flat plate portion 141 on the side close to the air inlet grille 115 and a convex portion 142 on the side close to the heat exchanger 120. The convex portion 142 is fixed to the tube sheet 121, and the front end of the flat plate portion 141 is fixed to the support portion 152 on the right side. Since both the convex portion 142 and the flat plate portion 141 are part of the baffle 140, and the convex portion 142 is fixed to the tube sheet 121, in fact, the baffle 140 is fixed to the heat exchanger 120; the front end of the flat plate portion 141 is fixed to the support portion 152 on the right side, in fact, the baffle 140 is fixed to the air inlet grille 115. That is to say, the baffle 140 is fixed to the heat exchanger 120 and the air inlet grille 115 respectively, so that the heat exchanger 120 and the air inlet grille 115 are indirectly fixed together.

[0080] For the vertical air conditioner indoor unit 100 of this embodiment, considering the optimal utilization efficiency of the heat exchanger 120, the elbow 122 of the heat exchanger 120 is relatively close to the air inlet grille 115 on the right side, and there is a risk that the air inlet grille 115 is deformed and touches the elbow 122 during transportation and dropping. That is to say, the baffle 140 is arranged between the heat exchanger 120 and the air inlet grille 115 to achieve the function of buffering during dropping. In fact, it is to avoid the collision between the elbow 122 of the heat exchanger 120 and the air inlet grille 115, which may cause component damage, and effectively reduce various impacts during the transportation process.

[0081] The indoor unit 100 of the floor-standing air conditioner may further include: a filter screen (not shown in the figure), which is disposed at the air inlet grille 115 and configured to perform primary filtration on the air entering the cavity 111. Moreover, the baffle 140 is further configured to: serve as a track for the filter screen so that the filter screen can slide in and be installed. Since the integrated air inlet grille 115 is limited by the problem of the ejection slant of the mold, it is impossible to make a filter screen track structure. Therefore, it is very important that the baffle 140 in this embodiment serves as a track for the filter screen, which enables the filter screen to slide in and be installed.

[0082] In addition, the internal components can often be seen through the air inlet grille at the rear of the current indoor unit of the floor-standing air conditioner, such as the elbow part of the heat exchanger, which affects the visual effect of the whole machine. The baffle 140 of the indoor unit 100 of the floor-standing air conditioner in this embodiment can also be configured to: serve as an object to block the elbow 122 to prevent the elbow 122 from being seen from behind the air inlet grille 115. That is to say, for the indoor unit 100 of the floor-standing air conditioner in this embodiment, by setting the baffle 140, a single component can achieve multiple functions, effectively simplifying the structure of the indoor unit 100 of the floor-standing air conditioner and effectively improving the visual effect of the whole machine of the indoor unit 100 of the floor-standing air conditioner.

[0083] In a specific embodiment, the vertical swing blades of the first vertical swing blade 161 and the second vertical swing blade 162 can be configured to adjust the left-right air outlet direction at the air outlet 117, and the horizontal swing blades of the first horizontal swing blade 171 and the second horizontal swing blade 172 can be configured to adjust the up-down air outlet direction at the air outlet 117. In a specific embodiment, the horizontal swing blades and the vertical swing blades are configured to adjust the specific postures according to the air supply mode. For example, the air supply mode may include a variety of different air supply instructions, and the horizontal swing blades and the vertical swing blades can adjust the specific postures according to different air supply instructions.

[0084] More specifically, the specific postures of the vertical swing blades may include facing left, facing middle, and facing right. The specific postures of the horizontal swing blades include facing up, facing middle, and facing down. In a preferred embodiment, the horizontal swing blades and the vertical swing blades can also adjust the specific angles of the air outlet to achieve different air volumes. For example, when facing left, the air outlet angles of the vertical swing blades can be different. When facing up, the air outlet angles of the horizontal swing blades can be different.

[0085] Regarding the specific postures of the horizontal swing blades, it should be noted that when the horizontal swing blades face up, the indoor unit 100 of the floor-standing air conditioner realizes upward air outlet, which is more suitable for the case where the indoor unit 100 of the floor-standing air conditioner operates in the cooling mode. Since the cold air is sent out by the indoor unit 100 of the floor-standing air conditioner in the cooling mode, according to the characteristics of the cold air, it will gradually sink after being blown upward, so that the temperature of the entire indoor environment can be reduced. The prevention of direct blowing of cold air can also effectively prevent users from having headaches, colds and other conditions.

[0086] The horizontal swing blades face downward, enabling the indoor unit 100 of the vertical air conditioner to blow air downward, which is more suitable for the case where the indoor unit 100 of the vertical air conditioner operates in the heating mode. Since the hot air is sent out by the indoor unit 100 of the vertical air conditioner in the heating mode, according to the characteristics of the hot air, it will gradually rise after being blown downward, so that the temperature of the entire indoor environment can be increased. Blowing the hot air downward can also more effectively blow towards the user, making the user feel warm and comfortable.

[0087] In addition, an air outlet guide plate (not shown in the figure) can be provided at the air outlet 117, configured to open and close the air outlet 117. When the air outlet guide plate opens the air outlet 117, the air guided by the first vertical swing blade 161, the second vertical swing blade 162, the first horizontal swing blade 171 and the second horizontal swing blade 172 can be sent to the indoor environment. If the air outlet guide plate closes the air outlet 117, no air will blow out at the air outlet 117. Generally, when the indoor unit 100 of the vertical air conditioner is closed, the air outlet guide plate can close the air outlet 117 to prevent external dust from entering the interior of the housing 110 through the air outlet 117, effectively ensuring the cleanliness of the interior of the housing 110.

[0088] In summary, the indoor unit 100 of the vertical air conditioner in this embodiment includes: a housing 110, with an air outlet 117 opened at its front; and a first vertical swing blade 161 and a second vertical swing blade 162, respectively arranged at the left end and the right end of the air outlet 117, and the first vertical swing blade 161 and the second vertical swing blade 162 are arranged in a staggered manner front and back. By setting the double-layer vertical swing blades, the swing effect of the air can be improved, effectively improving the overall energy efficiency while enhancing the user experience.

[0089] Furthermore, in the indoor unit 100 of the vertical air conditioner in this embodiment, a first motor is connected to the first vertical swing blade 161, configured to control the rotation angle of the first vertical swing blade 161; a second motor is connected to the second vertical swing blade 162, configured to control the rotation angle of the second vertical swing blade 162; when the rotation angle of the first vertical swing blade 161 is a first angle and the rotation angle of the second vertical swing blade 162 is a second angle, a difference in air feeling is achieved; when the rotation angle of the first vertical swing blade 161 is a third angle and the rotation angle of the second vertical swing blade 162 is a fourth angle, parallel soft wind is achieved; when the rotation angle of the first vertical swing blade 161 is a fifth angle and the rotation angle of the second vertical swing blade 162 is a sixth angle, wide-angle air outlet is achieved, which can expand various air outlet forms and fully meet the user's usage requirements.

[0090] Furthermore, for the indoor unit 100 of the vertical air conditioner in this embodiment, by providing the air supplement structure 132, the problems of air volume obstruction and slow air speed at one end of the rear scroll tongue 113 of the indoor unit 100 of the vertical air conditioner can be solved, effectively improving the overall energy efficiency and enhancing the user experience; the air diffusing structure 160 is arranged to increase the air inlet area of the heat exchanger 120, thereby improving the heat exchange efficiency of the heat exchanger 120, ensuring the heat exchange effect of the indoor unit 100 of the vertical air conditioner, and fully meeting the user's usage requirements; by providing the baffle 140 between the heat exchanger 120 and the air inlet grille 115, the transportation impact can be effectively reduced, and it can be avoided that the deformation of the air inlet grille 115 caused by transportation drop collides with the heat exchanger 120, ensuring the working reliability of the indoor unit 100 of the vertical air conditioner and enhancing the user experience.
