Description

TECHNICAL FIELD

[0001] The present application relates to the field of household electrical appliances, in particular to an air conditioner indoor unit. BACKGROUND

[0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical appliances in people's daily life. Various air conditioning devices can help people reach an adaptable temperature when the environmental temperature is too high or too low. The current air conditioning devices mainly include various types of air conditioners and fans.

[0003] Air conditioners can be divided into integrated air conditioners and split air conditioners, wherein the split air conditioner can include an air conditioner indoor unit and an air conditioner outdoor unit. As the popularity of integrated decoration improves, the requirements for the air conditioner indoor unit are gradually increasing, not only in terms of appearance value and superior performance, but also in terms of meeting the needs of home decoration. The embedded air conditioner indoor unit not only has the functions of a general air conditioner indoor unit, but also can be integrated with the style of the cabinet. Embedding the air conditioner indoor unit in the cabinet forms a whole in form, which is more beautiful.

[0004] When the air conditioner indoor unit is embedded for use, the air inlet mode similar to the traditional wall-mounted air conditioner indoor unit is not applicable. Because the traditional wall-mounted air conditioner indoor unit generally inlets air through the top air inlet, after the air conditioner indoor unit is embedded in the cabinet, the top will be blocked by the cabinet, affecting air inlet. And the decrease of air inlet amount will cause the indoor heat exchanger of the air conditioner indoor unit to be unable to fully exchange heat, which is easy to cause icing phenomenon, affecting the normal work of the indoor heat exchanger. In addition, if the motor fails when the air conditioner indoor unit is embedded in the cabinet, it is not convenient to replace without disassembling the machine and defrosting. Only after defrosting, the air conditioner indoor unit can be completely disassembled from the cabinet, and then replaced, which is very inconvenient and affects the user's experience. SUMMARY

[0029] The embodiment provides an indoor unit of an air conditioner, which can provide an indoor unit of an air conditioner convenient for disassembling and assembling motor components, save time and effort of users or maintenance personnel, reduce maintenance cost, and improve convenience. Figure 1 is a schematic view of the overall structure of an indoor unit 100 of an air conditioner according to an embodiment of the present application, Figure 2 is a schematic view of the internal structure of an indoor unit 100 of an air conditioner according to an embodiment of the present application, Figure 3 is a schematic view of the partial structure of an indoor unit 100 of an air conditioner according to an embodiment of the present application, Figure 4 is a schematic view of the connection structure of a fan 112 and a motor assembly 150 of an indoor unit 100 of an air conditioner according to an embodiment of the present application, Figure 5 is Figure 4 is a schematic view of the structure from another angle, Figure 6 is a schematic view of the exploded structure of a motor assembly 150 of an indoor unit 100 of an air conditioner according to an embodiment of the present application. As Figures 1 to 6 shown, the indoor unit 100 of the air conditioner according to the embodiment can generally include a housing 110, an indoor heat exchanger 111, a fan 112, and a motor assembly 150.

[0030] The shell 110 has an inner cavity 113. The indoor heat exchanger 111 is arranged in the cavity 113 and configured to exchange heat with air entering the cavity 113. The fan 112 is arranged below the indoor heat exchanger 111 and configured to blow the air exchanged by the indoor heat exchanger 111. Specifically, when the air conditioner indoor unit 100 operates in a cooling mode, the air exchanged by the indoor heat exchanger 111 is cold air, which can reduce the temperature of the indoor environment after being sent to the indoor environment. When the air conditioner indoor unit 100 operates in a heating mode, the air exchanged by the indoor heat exchanger 111 is hot air, which can increase the temperature of the indoor environment after being sent to the indoor environment.

[0031] The motor assembly 150 can include a motor body 130, a motor bracket 140, and two motor glands. The motor body 130 is connected with the fan 112 and configured to drive the fan 112 to rotate. The motor bracket 140 is sleeved outside the motor body 130. The two motor glands are respectively arranged on the left end surface 131 and the right end surface 132 of the motor body 130. The unique structure of the motor assembly 150 can provide an air conditioner indoor unit 100 with convenient disassembly and assembly of the motor components, saving time and effort of users or maintenance personnel, reducing maintenance costs, and improving convenience.

[0032] In a specific embodiment, the motor bracket 140 includes a first flat portion 141, a second flat portion 142, and a curved portion 143 between the first flat portion 141 and the second flat portion 142. The first flat portion 141 is in contact with the left end surface 131 of the motor body 130. The second flat portion 142 is in contact with the right end surface 132 of the motor body 130. The curved portion 143 is in contact with part of the peripheral wall of the motor body 130.

[0033] In a specific embodiment, the left end surface 131 of the motor body 130 has a first screw disc 133 protruding to the left. The right end surface 132 has a second screw disc 134 protruding to the right. The rear side of the first flat portion 141 extends to the left to form a first extension 144, which is in close contact with part of the peripheral wall of the first screw disc 133. The rear side of the second flat portion 142 extends to the right to form a second extension 145, which is in close contact with part of the peripheral wall of the second screw disc 134. In addition, the two motor glands can include a first gland 151 and a second gland 152. The first gland 151 has a first curved portion 153, which is in close contact with another part of the peripheral wall of the first screw disc 133. The second gland 152 has a second curved portion 154, which is in close contact with another part of the peripheral wall of the second screw disc 134.

[0034] In a preferred embodiment, the first extension 144 is snapped into one end of the first bent portion 153 and screwed into the other end; the second extension 145 is snapped into one end of the second bent portion 154 and screwed into the other end, so that the motor bracket 140, the motor body 130, and the two motor covers are fixed as a whole to form a motor assembly 150. The unique structural design of the motor assembly 150 provides an air conditioner indoor unit 100 that facilitates the disassembly and assembly of motor components, saving time and effort for users or maintenance personnel, reducing maintenance costs, and improving convenience.

[0035] In one specific embodiment, the motor bracket 140 and the two motor covers can be made of ABS resin (Acrylonitrile Butadiene Styrene). ABS resin, as a high-strength, tough, and easily processed thermoplastic polymer material, is very suitable for the application scenario of the motor bracket 140 and the two motor covers in this embodiment. This results in the motor bracket 140 and the two motor covers being high-strength, corrosion-resistant, and high-temperature resistant, ensuring the operational reliability of the motor assembly 150.

[0036] In a preferred embodiment, the indoor unit 100 of the air conditioner may further include: a rubber component disposed on the left end face 131 and the right end face 132 of the motor body 130, in contact with the motor bracket 140 and the motor cover to reduce vibration and noise. Specifically, when the motor body 130 is working, that is, when driving the fan 112 to rotate, vibration and noise are often generated. The rubber component can effectively reduce vibration and noise.

[0037] In one specific embodiment, the indoor unit 100 of the air conditioner may further include: a frame 161 disposed in the cavity 113, and a motor assembly 150 fixed as a whole connected and fixed to the side of the frame 161. That is, the motor body 130, the motor bracket 140 and the two motor covers can be assembled into a whole motor assembly 150 first, and then the motor assembly 150 can be connected to the frame 161. Figure 3 The motor assembly 150 is shown to be located on the right side of the cavity 113, and the motor assembly 150 is connected and fixed to the right side of the frame 161.

[0038] It should be noted that in some other embodiments, the motor assembly 150 can be disposed on the left side of the cavity 113, and thus can be fixed to the left side of the frame 161. When the motor assembly 150 is disposed on the left side of the cavity 113, the arrangement of the motor body 130, the motor bracket 140 and the two motor covers can be similar to that described above, except that the overall arrangement is symmetrical to that when the motor assembly 150 is disposed on the right side of the cavity 113.

[0039] In one specific embodiment, the fan 112 is screwed to the shaft 135 of the motor body 130 so that the fan 112 is driven to rotate when the shaft 135 rotates. More specifically, the fan 112 may have a screw hole through which a screw passes to fix the fan 112 to the shaft 135 of the motor body 130. Figures 3 to 5 The fan 112 shown is only part of the complete structure. The complete fan 112 extends from the left side to the right side of the cavity 113. The motor body 130 is fixed to the fan 112, which also makes the assembled motor assembly 150 fixed to the fan 112 as one unit. This allows for easy assembly and disassembly of the motor assembly 150 and the fan 112.

[0040] Figure 7 This is a side sectional view of the housing 110 of an indoor unit 100 of an air conditioner according to an embodiment of the present invention. Figure 8 This is an exploded view of an air conditioner indoor unit 100 embedded in a cabinet according to an embodiment of the present invention. In a specific embodiment, the air conditioner indoor unit 100 may further include a panel 120. The panel 120 may be disposed on the front side of the housing 110, with an air inlet 121 at the upper part and an air outlet 122 at the lower part. Air can enter the interior of the housing 110 through the air inlet 121, and after heat exchange by the indoor heat exchanger 111, it can be delivered to the indoor environment through the air outlet 122.

[0041] In one specific embodiment, such as Figure 7 As shown, the housing 110 internally defines a first channel 115 and a second channel 116, with the air inlet of the first channel 115 higher than the air inlet of the second channel 116. In fact, the air inlets of both the first channel 115 and the second channel 116 are part of the air inlet 121. That is, some of the air entering the housing 110 from the air inlet 121 flows through the first channel 115, and some flows through the second channel 116.

[0042] Furthermore, both the first channel 115 and the second channel 116 are equipped with indoor heat exchangers 111. In a specific embodiment, such as... Figure 4 As shown, the indoor heat exchanger 111 is segmented and includes a front heat exchanger 117, a middle heat exchanger 118 and a rear heat exchanger 119 from front to back. The front heat exchanger 117 and the middle heat exchanger 118 are located in the second channel 116, and the rear heat exchanger 119 is located in the first channel 115.

[0043] Depend on Figure 7It can be seen that the front heat exchanger 117 and the middle heat exchanger 118 are closer to the air inlet 121 than the rear heat exchanger 119. Under normal circumstances, most of the air entering the casing 110 through the air inlet 121 flows to the front heat exchanger 117 and the middle heat exchanger 118, while less air flows through the rear heat exchanger 119. This may lead to insufficient overall airflow, resulting in problems such as icing in the indoor heat exchanger 111. In this embodiment, by setting two channels inside the casing 110, and making the airflow of the first channel 115 stronger than that of the second channel 116, more air can enter the first channel 115 through the air inlet 121 and exchange heat through the rear heat exchanger 119 in the first channel 115, effectively solving the problem of icing in the indoor heat exchanger 111 caused by insufficient airflow.

[0044] In one specific embodiment, such as Figure 7 As shown, a fan 112 can be installed below the indoor heat exchanger 111, configured to blow the air that has been heated by the indoor heat exchanger 111 toward the air outlet 122. More specifically, as... Figure 7 As shown, the front heat exchanger 117 can be set in a basically vertical position, the middle heat exchanger 118 can be set to gradually rise from front to back, and the rear heat exchanger 119 can be set to gradually lower from front to back, so that the space below where the fan 112 is housed is defined by the front heat exchanger 117, the middle heat exchanger 118 and the rear heat exchanger 119.

[0045] Furthermore, the stronger airflow in the first channel 115 compared to the second channel 116 can be achieved through specific settings of the fan 112. For example, the suction direction of the fan 112 can be adjusted to be more towards the downstream heat exchanger 119, making the airflow in the first channel 115 stronger than that in the second channel 116. Alternatively, in some other embodiments, the fan 112 can also be adjusted in other ways to achieve the same effect.

[0046] like Figure 8 As shown, the indoor unit 100 of the air conditioner can be housed in a cabinet 200 with a front opening 210 and the panel 120 facing forward. Specifically, the cabinet 200 may define a storage space 220, and the indoor unit 100 can be housed in the storage space 220. In one specific embodiment, the indoor unit 100 can be placed directly in the storage space 220. In other embodiments, the indoor unit 100 can be fixed to the cabinet 200 in some ways, such as fixing the casing 110 of the indoor unit 100 to the cabinet 200, to improve overall stability.

[0047] It is important to emphasize that the air intake method of traditional wall-mounted air conditioner indoor units is not suitable for recessed installation. Traditional wall-mounted air conditioner indoor units typically draw air in through a top-mounted vent. Once the indoor unit is recessed into a cabinet, the top of the cabinet will obstruct the airflow, affecting its operation. Furthermore, reduced airflow can lead to insufficient heat exchange by the indoor heat exchanger, potentially causing icing and hindering its normal function.

[0048] The indoor unit 100 of this air conditioner adopts a front-intake and front-outtake airflow design, and uses a dual-channel scheme inside the casing 110. This allows the air entering the casing 110 through the air inlet 121 to be fully guided to the rear heat exchanger 119, avoiding icing of the indoor heat exchanger 111 due to insufficient airflow. At the same time, it achieves front-intake and front-outtake airflow, without being restricted by the cabinet 200.

[0049] In a preferred embodiment, such as Figure 8 As shown, the air inlet 121 is provided with a rotatable plate 123. The rotatable plate 123 is configured to rotate in a controlled manner around a horizontal rotation axis below it to open and close the air inlet 121. In one specific embodiment, the rotatable plate 123 can be driven to rotate by a motor and a linkage mechanism 125. When the motor drives the linkage mechanism 125 to open the rotatable plate 123, the air inlet 121 opens; when the motor drives the linkage mechanism 125 to retract the rotatable plate 123, the air inlet 121 closes. Furthermore, when the motor drives the linkage mechanism 125 to open the rotatable plate 123, the opening area of ​​the air inlet 121 varies depending on the rotation angle of the rotatable plate 123. In one specific embodiment, a filter screen 124 can also be provided at the air inlet 121 to pre-filter the air entering the housing 110 from the air inlet 121, preventing excessive dust and other impurities from entering the cavity 113.

[0050] In this embodiment, the indoor unit 100 of the air conditioner is designed with two parts: a front panel 120 and a housing 110. This design facilitates both assembly and maintenance. Specifically, during assembly, the rear housing 110 and related structures can be installed into the cabinet 200 first, followed by the front panel 120 and related structures. This allows for easy maintenance of the rear housing 110 when the front panel 120 is open. Furthermore, after the panel 120 and housing 110 are assembled, the rear housing 110 is not visible and is not considered an external component, allowing for lower requirements and effectively reducing costs.

[0051] Specifically, the front panel 120 mainly includes the aforementioned rotatable plate 123, a motor and linkage mechanism 125 for driving the rotatable plate 123 to rotate, and may also include a display panel box, which can be used to display relevant information of the indoor unit 100 of the air conditioner, such as operating mode and set temperature. The rear housing 110 mainly includes the aforementioned indoor heat exchanger 111 and fan 112.

[0052] A drip tray 162 can be installed below the indoor heat exchanger 111 to collect and hold the condensate produced by the indoor heat exchanger 111. By simply removing the drip tray 162 and related front components such as the panel 120, the motor assembly 150 and fan 112 can be exposed, allowing for easy disassembly and maintenance without having to remove the entire indoor unit 100 of the air conditioner, thus effectively improving maintenance convenience.

[0053] When the indoor unit 100 of the air conditioner is operating in cooling mode, the air that has undergone heat exchange through the indoor heat exchanger 111 is cold air. After being delivered to the indoor environment through the air outlet 122, it can lower the temperature of the indoor environment and make the user feel cool. When the indoor unit 100 of the air conditioner is operating in heating mode, the air that has undergone heat exchange through the indoor heat exchanger 111 is hot air. After being delivered to the indoor environment through the air outlet 122, it can raise the temperature of the indoor environment and make the user feel warm.

[0054] In one specific embodiment, the indoor unit 100 of the air conditioner can activate either cooling or heating mode after receiving a user's activation trigger signal. More specifically, it can receive activation trigger signals sent by the user through the display device, voice device, remote control, or a mobile terminal bound to the indoor unit 100. The mobile terminal can be a portable smart device, such as a smartphone or tablet.

[0055] The fan 112 delivers the air heated by the indoor heat exchanger 111 to the indoor environment through the air outlet 122. In this embodiment, the fan 112 is a cross-flow fan, also known as a horizontal flow fan. Airflow enters radially from the open end of the impeller, passes through the interior of the impeller, and exits into the volute from the other side of the impeller, forming the working airflow. In an axial flow fan, the airflow is axial within the impeller. The airflow and speed of the fan 112 can be adjusted by regulating the rotational speed of the motor body 130, thereby adjusting the air delivery effect of the indoor unit 100 of the air conditioner.

[0056] In one specific embodiment, a guide plate 126 and a swivel blade 127 may also be provided at the air outlet 122. The swivel blade 127 can be configured to adjust the air outlet direction at the air outlet 122. In one specific embodiment, the swivel blade 127 is configured to adjust its specific posture according to the air supply mode. For example, the air supply mode may include a variety of different air supply commands, and the swivel blade 127 can adjust its specific posture according to different air supply commands. The guide plate 126 can be configured to open and close the air outlet 122. When the guide plate 126 opens the air outlet 122, the air guided by the swivel blade 127 can be delivered to the indoor environment. If the guide plate 126 closes the air outlet 122, no air will blow out from the air outlet 122. Generally, when the indoor unit 100 of the air conditioner is turned off, the guide plate 126 can close the air outlet 122 to prevent external dust from entering the interior of the housing 110 through the air outlet 122, effectively ensuring the cleanliness of the interior of the housing 110.

[0057] In summary, the indoor unit 100 of this embodiment includes: a housing 110, which defines a cavity 113 inside; an indoor heat exchanger 111 disposed in the cavity 113 and configured to exchange heat with the air entering the cavity 113; a fan 112 disposed below the indoor heat exchanger 111 and configured to blow out the air that has been heated by the indoor heat exchanger 111; and a motor assembly 150, including a motor body 130, a motor bracket 140, and two motor covers, wherein the motor body 130 is connected to the fan 112 and configured to drive the fan 112 to rotate, the motor bracket 140 is sleeved on the outside of the motor body 130, and the two motor covers are respectively pressed on the left end face 131 and the right end face 132 of the motor body 130. This provides an indoor unit 100 of the air conditioner that is easy to disassemble and assemble, saving time and effort for users or maintenance personnel, reducing maintenance costs, and improving convenience.

[0058] Furthermore, in this embodiment, the indoor unit 100 of the air conditioner has a housing 110 that defines a first channel 115 and a second channel 116. The air inlet of the first channel 115 is higher than the air inlet of the second channel 116, and an indoor heat exchanger 111 is provided in both the first channel 115 and the second channel 116. The indoor heat exchanger 111 is segmented and includes a front heat exchanger 117, a middle heat exchanger 118, and a rear heat exchanger 119 from front to back. The front heat exchanger 117 and the middle heat exchanger 118 are located in the second channel 116, and the rear heat exchanger 119 is located in the second channel 116. The heat exchanger 119 is located in the first channel 115; the air intake of the first channel 115 is stronger than that of the second channel 116, so that more air enters the first channel 115 through the air inlet 121 and is heat-exchanged through the downstream heat exchanger 119. The indoor unit 100 of the air conditioner is installed in the cabinet 200 with a front opening 210 and the panel 120 faces forward, so that the indoor unit 100 of the air conditioner is embedded in the cabinet 200 while increasing the air intake volume, avoiding the phenomenon of icing of the indoor heat exchanger 111 due to insufficient air volume, and improving the working reliability of the indoor heat exchanger 111.
