[0022] Figure 3 is a cross-sectional view of an indoor unit of a floor-standing air conditioner according to an embodiment of the present invention. Detailed Description of the Embodiment

[0023] This embodiment provides an indoor unit of a floor-standing air conditioner. By providing a first air supply compensation structure, the problem of air volume obstruction at the part where the heat exchanger extends into the front door panel can be effectively solved, the air volume and energy efficiency can be effectively improved, and the user experience can be enhanced. Figure 1 is a front view of an indoor unit 100 of a floor-standing air conditioner according to an embodiment of the present invention, Figure 2 is a side view of an indoor unit 100 of a floor-standing air conditioner according to an embodiment of the present invention, Figure 3 is a cross-sectional view of an indoor unit 100 of a floor-standing air conditioner according to an embodiment of the present invention. As Figures 1 to 3 shown, the indoor unit 100 of the floor-standing air conditioner in this embodiment generally may include: a housing 110, a heat exchanger 120, and a first air supply compensation structure 131.

[0024] Among them, a cavity 111 may be defined inside the housing 110, and the housing 110 may include a front door panel 112. The heat exchanger 120 may be disposed in the cavity 111 and configured to exchange heat with the air entering the cavity 111. The first end 121 of the heat exchanger 120 extends into the front door panel 112. The first air supply compensation structure 131 may be disposed behind the heat exchanger 120 and near the first end 121, and is configured to make up for the air volume blocked by the front door panel 112 at the first end 121. For the indoor unit 100 of the floor-standing air conditioner in this embodiment, by providing the first air supply compensation structure 131, the problem of air volume obstruction at the part where the heat exchanger 120 extends into the door panel can be effectively solved, the air volume and energy efficiency can be effectively improved, and the user experience can be enhanced.

[0025] 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 commonly 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 with the wall-mounted air conditioner indoor unit, and the 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 cooling, heating, and air supply effects.

[0026] However, as mentioned above, 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.

[0027] Moreover, reducing the body thickness of the current floor-standing air conditioner indoor unit 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.

[0028] Specifically, in order to reduce the body thickness of the floor-standing air conditioner indoor unit 100, in this embodiment, the first end 121 of the heat exchanger 120 extends into the front door panel 112, and a first air supply compensation structure 131 is provided at the rear side of the heat exchanger 120 and near the first end 121. By setting the first air supply compensation structure 131, the problem of air volume blockage 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 enhanced.

[0029] For the floor-standing air conditioner indoor unit 100 of this embodiment, by setting the first air supply compensation structure 131, the body thickness of the floor-standing air conditioner indoor unit 100 can be effectively reduced on the premise of ensuring the air volume. Preferably, the body thickness T of the floor-standing air conditioner indoor unit 100 of this embodiment is less than 370 mm, which can improve the overall aesthetics 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 scenarios, making it possible to install in spaces that were previously restricted by the body thickness and unable to be installed.

[0030] In a specific embodiment, the body thickness T of the floor-standing air conditioner indoor unit 100 can be 330 to 340 mm. Preferably, the body thickness T of the floor-standing air conditioner indoor unit 100 can be 331 mm. This body thickness T of the floor-standing air conditioner indoor unit 100 in this embodiment has achieved a great reduction compared with the conventional body thickness of 370 mm or even more. It should be noted that the specific values of the above body thickness T are only examples and are not limitations of the present invention. In some other embodiments, it can also be set to other values according to actual situations, but all can be less than 370 mm.

[0031] In a preferred embodiment, the housing 110 of the floor-standing air conditioner indoor unit 100 can further include: a rear scroll tongue 113, one end of the rear scroll tongue 113 is connected to the front door panel 112. And the second end 122 of the heat exchanger 120 can be located at the rear side of the rear scroll tongue 113. This may cause the air volume at the second end 122 of the heat exchanger 120 to be blocked by the rear scroll tongue 113, resulting in air volume loss. Therefore, in a preferred embodiment, the floor-standing air conditioner indoor unit 100 of this embodiment can further include: a second air supply compensation structure 132, which is arranged at the rear side of the heat exchanger 120 and close to the second end 122, and is configured to make up for the air volume blocked by the rear scroll tongue 113 at the second end 122. The second 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.

[0032] In a specific embodiment, the housing 110 can further include: an air inlet grille 115, which is connected to the front door panel 112, and an air inlet 116 is arranged on the air inlet grille 115, and is configured to allow the air in the indoor environment to enter the cavity 111 through the air inlet 116. The housing 110 further includes: a front scroll tongue 114, one end of the front scroll tongue 114 is connected to the front door panel 112. An air outlet 117 is formed between the front scroll tongue 114 and the rear scroll tongue 113.

[0033] Actually, the housing 110 can include a front door panel 112 and a rear panel 119, and the air inlet grille 115 can be arranged on the rear panel 119. A filter screen can be arranged 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, and improve the cleanliness of the interior of the floor-standing air conditioner indoor unit 100 and the finally blown air. The formation of the air outlet 117 between the front scroll tongue 114 and the rear scroll tongue 113 can also be reflected on the front door panel 112.

[0034] 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 appearance of the vertical air conditioner indoor unit 100 better and make the vertical air conditioner indoor unit 100 more stable when installed in the 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.

[0035] 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 heated by the heat exchanger 120 is cold air, and after being sent to the indoor environment through the air outlet 117, it can reduce the temperature of the indoor environment, making the user feel cool. When the vertical air conditioner indoor unit 100 operates in the heating mode, the air heated by the heat exchanger 120 is hot air, and after being sent to the indoor environment through the air outlet 117, it can increase the temperature of the indoor environment, making the user feel warm.

[0036] In a specific embodiment, the vertical air conditioner indoor unit 100 can turn on the cooling mode or the heating mode after receiving the user's activation trigger signal. More specifically, it can receive the activation trigger signal sent by the user through the display device, voice device, remote controller 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.

[0037] 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 heat by the heat exchanger 120, improving the heat exchange efficiency. Specifically, the heat exchanger 120 of the vertical air conditioner indoor unit 100 in this embodiment can be V-shaped and bent backward. 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 makes the situation of air inlet blockage of the part of the heat exchanger 120 extending into the front door panel 112 more serious. Therefore, in this embodiment, it is very crucial and effective to solve the problem of air volume blockage of the part of the heat exchanger 120 extending into the door panel by setting the first air supply compensation structure 131.

[0038] In addition, a supply air fan 130 may be provided in the cavity 111 inside the housing 110, 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 through the air outlet 117. The fans of the vertical air conditioner indoor unit 100 mainly include three types: centrifugal, cross-flow, and axial-flow. Among them, the air inside the centrifugal fan is affected by the centrifugal force, generating a vacuum degree in the center of the impeller. The inhaled air turns 90° at the impeller inlet and then enters the flow channel formed by the blades, obtaining kinetic energy and pressure energy under the action of the blades. The airflow ejected from the blade channel enters the volute, and after concentration and diversion, it is discharged from the outlet of the centrifugal fan.

[0039] The cross-flow fan can also be called a tubular fan. The airflow 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 the working airflow. The airflow in the axial-flow fan flows axially inside the impeller. The above three types of fans each have their own advantages and disadvantages and can be set according to the actual situation. However, no matter which type of fan, it can send the air heated by the heat exchanger 120 to the indoor environment through the air outlet 117 to adjust the temperature of the indoor environment.

[0040] A motor may also be correspondingly provided for the supply air fan 130, 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. In a preferred embodiment, the supply air fan 130, the first air supply structure 131, and the second air supply structure 132 may all be tubular fans. This is because the axial length of the tubular fan is not limited, and the length of the impeller can be arbitrarily selected according to different usage requirements. Moreover, the airflow flows through the impeller, and is affected by the blades twice, so the airflow can reach a long distance and the air supply is relatively far. In addition, the tubular fan has no turbulent flow, the air outlet is uniform, and the noise is low, which can effectively improve the user experience.

[0041] It should be emphasized that the volumes of the first air supply structure 131 and the second air supply structure 132 of the vertical air conditioner indoor unit 100 in this embodiment are relatively small compared to the supply air fan 130. While the supply air fan 130 plays the main air supply role, the first air supply structure 131 and the second air supply structure 132 play an effective supplementary and cooperative role to make up for the blocked air volume 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 supply air fan 130, the first air supply structure 131, and the second air supply structure 132, which can effectively increase the air volume. In a specific embodiment, the air volume can be increased by about 40% compared to the traditional single-fan air supply. At the same time, the energy efficiency ratio APF of the vertical air conditioner indoor unit 100 can also be increased by about 25%.

[0042] In a specific embodiment, a horizontal swing blade (not shown in the figure) and a vertical swing blade 118 may also be provided at the air outlet 117. The vertical swing blade 118 may be configured to adjust the left - right air outlet direction at the air outlet 117, and the horizontal swing blade may be configured to adjust the up - down air outlet direction at the air outlet 117. In a specific embodiment, the horizontal swing blade and the vertical swing blade 118 are configured to adjust their 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 blade and the vertical swing blade 118 may adjust their specific postures according to different air supply instructions.

[0043] More specifically, the specific postures of the vertical swing blade 118 may include facing left, facing middle, and facing right. The specific postures of the horizontal swing blade include facing up, facing middle, and facing down. In a preferred embodiment, the horizontal swing blade and the vertical swing blade 118 can also adjust the specific angle of the air outlet to achieve different air volumes. For example, even when facing left, the air outlet angles of the vertical swing blade 118 can be different. Even when facing up, the air outlet angles of the horizontal swing blade can be different.

[0044] Regarding the specific posture of the horizontal swing blade, it should be noted that when the horizontal swing blade faces 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 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 avoid situations such as headaches and colds for users.

[0045] When the horizontal swing blade faces down, the indoor unit 100 of the floor - standing air conditioner realizes downward air outlet, which is more suitable for the case where the indoor unit 100 of the floor - standing air conditioner operates in the heating mode. Since the hot air is sent out by the indoor unit 100 of the floor - standing air conditioner in the heating mode, according to the characteristics of hot air, it will gradually rise after being blown downward, so that the temperature of the entire indoor environment can be increased. Blowing hot air downward can also more effectively blow towards the user, making the user feel warm and comfortable.

[0046] In addition, an air outlet guide plate (not shown in the figure) may also 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 horizontal swing blade and the vertical swing blade 118 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 floor - standing air conditioner is turned off, 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.

[0047] In summary, the vertical air conditioner indoor unit 100 of this embodiment includes: a housing 110, with a cavity 111 defined inside it, and the housing 110 includes a front door panel 112; a heat exchanger 120, disposed in the cavity 111 and configured to exchange heat with the air entering the cavity 111, and a first end 121 of the heat exchanger 120 extends into the front door panel 112; and a first air supply compensation structure 131, disposed behind the heat exchanger 120 and near the first end 121, configured to compensate for the air volume blocked by the front door panel 112 at the first end 121. By setting the first air supply compensation structure 131, the problem of air volume obstruction at the part where the heat exchanger 120 extends into the door panel can be effectively solved, the air volume and energy efficiency can be effectively improved, and the user experience can be enhanced.

[0048] Furthermore, for the vertical air conditioner indoor unit 100 of this embodiment, the housing 110 further includes: a rear scroll tongue 113, with one end of the rear scroll tongue 113 connected to the front door panel 112; a second end 122 of the heat exchanger 120 is located behind the rear scroll tongue 113; a second air supply compensation structure 132 is disposed behind the heat exchanger 120 and near the second end 122, configured to compensate for the air volume blocked by the rear scroll tongue 113 at the second end 122, which can further increase the air volume and strongly boost the pressure. The specific settings of the first air supply compensation mechanism 131 and the second air supply compensation mechanism 132 can effectively reduce the body thickness of the vertical air conditioner indoor unit 100 on the premise of ensuring the air volume, so that the body thickness of the vertical air conditioner indoor unit 100 is less than a preset thickness, where the preset thickness is less than 370 mm, improving the overall aesthetics of the vertical air conditioner indoor unit 100 and reducing the occupied space.
