Description

Technical Field

[0001] The utility model relates to the field of household electrical appliances, in particular to an indoor unit of an air conditioner. Background Art

[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 devices in people's daily lives. Various air conditioning devices can help people reach a comfortable temperature when the ambient temperature is too high or too low. Current air conditioning devices mainly include various types of air conditioners and fans.

[0003] Air conditioners can be categorized as either integrated or split-type units. Split-type units consist of both an indoor unit and an outdoor unit. As integrated interior design becomes more prevalent, expectations for indoor units are also rising. They require not only aesthetically pleasing design and superior performance, but also compatibility with home decor requirements. Embedded indoor units not only offer the functionality of standard units but also blend seamlessly with the cabinet design. Embedding the indoor unit within the cabinet creates a cohesive, aesthetically pleasing design.

[0004] When the air conditioner indoor unit is embedded, the air intake method similar to that of traditional wall-mounted air conditioner indoor units is not applicable. This is because traditional wall-mounted air conditioner indoor units generally take in air through the air inlet on the top. After the air conditioner indoor unit is embedded in the cabinet, the top will be blocked by the cabinet, affecting the air intake. In addition, the reduced air intake will cause the indoor heat exchanger of the air conditioner indoor unit to not fully exchange heat, which is prone to icing and affecting the normal operation of the indoor heat exchanger. In addition, if the motor of the air conditioner indoor unit fails when it is embedded in the cabinet, it cannot be replaced without disassembling the unit and collecting the air. After collecting the air, the air conditioner indoor unit can only be completely removed from the cabinet and then replaced, which is very inconvenient and affects the user experience.

[0029] This embodiment provides an air conditioner indoor unit, which can provide an air conditioner indoor unit with easy disassembly and assembly of motor components, saving time and energy of users or maintenance personnel, reducing maintenance costs, and improving convenience. Figure 1 1 is a schematic diagram of the overall structure of an air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 2 1 is a schematic diagram of the internal structure of an air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 3 FIG1 is a partial structural diagram of an air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 4 1 is a schematic diagram of the connection structure between the fan 112 and the motor assembly 150 of the air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 5 yes Figure 4 Structural diagram from another angle. Figure 6 FIG. 1 is a schematic diagram of the exploded structure of the motor assembly 150 of the air conditioner indoor unit 100 according to an embodiment of the present invention. Figures 1 to 6 As shown, the air conditioner indoor unit 100 of this embodiment may generally include: a housing 110 , an indoor heat exchanger 111 , a fan 112 and a motor assembly 150 .

[0030] The interior of the housing 110 defines a cavity 113. The indoor heat exchanger 111 can be disposed in the cavity 113 and configured to perform heat exchange on the air entering the cavity 113. The fan 112 can be disposed below the indoor heat exchanger 111 and configured to blow out the air that has exchanged heat through the indoor heat exchanger 111. Specifically, when the air conditioner indoor unit 100 operates in cooling mode, the air that has exchanged heat through the indoor heat exchanger 111 is cold air, which can lower the ambient temperature after being sent to the indoor environment. When the air conditioner indoor unit 100 operates in heating mode, the air that has exchanged heat through the indoor heat exchanger 111 is hot air, which can raise the ambient temperature after being sent to the indoor environment.

[0031] The motor assembly 150 may include a motor body 130, a motor bracket 140, and two motor glands. The motor body 130 is connected to the fan 112 and configured to drive the fan 112 to rotate. The motor bracket 140 is mounted externally to the motor body 130, and the two motor glands are respectively mounted on the left end surface 131 and the right end surface 132 of the motor body 130. This embodiment, through the unique structural arrangement of the motor assembly 150, provides an air conditioner indoor unit 100 that facilitates the assembly and disassembly of motor components, saving time and effort for users or maintenance personnel, reducing maintenance costs, and improving convenience.

[0032] In a specific embodiment, the motor bracket 140 includes a first planar portion 141, a second planar portion 142, and a curved portion 143 between the first planar portion and the second planar portion 142. Furthermore, the first planar portion contacts the left end surface 131 of the motor body 130, the second planar portion 142 contacts the right end surface 132 of the motor body 130, and the curved portion 143 contacts a portion 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 disk 133 protruding to the left, and the right end surface 132 has a second screw disk 134 protruding to the right. In addition, the rear side of the first flat portion 141 extends leftward to form a first extension portion 144, which is closely attached to a portion of the circumferential wall of the first screw disk 133. The rear side of the second flat portion 142 extends rightward to form a second extension portion 145, which is closely attached to a portion of the circumferential wall of the second screw disk 134. In addition, the two motor glands may include: a first gland member 151 and a second gland member 152, wherein the first gland member 151 has a first curved portion 153, which is closely attached to another portion of the circumferential wall of the first screw disk 133, and the second gland member 152 has a second curved portion 154, which is closely attached to another portion of the circumferential wall of the second screw disk 134.

[0034] In a preferred embodiment, the first extension 144 is snap-fitted to one end of the first curved portion 153 and screwed to the other end; the second extension 145 is snap-fitted to one end of the second curved portion 154 and screwed to the other end, thereby securing the motor bracket 140, the motor body 130, and the two motor glands to form a single motor assembly 150. The unique structure of the motor assembly 150 provides an air conditioner indoor unit 100 that facilitates assembly and disassembly of motor components, saving time and effort for users or maintenance personnel, reducing maintenance costs, and improving convenience.

[0035] In a specific embodiment, the motor bracket 140 and the two motor glands can be made of ABS resin (Acrylonitrile Butadiene Styrene). ABS resin, as a thermoplastic polymer material with high strength, good toughness, and ease of processing and molding, is highly suitable for the application scenarios of the motor bracket 140 and the two motor glands in this embodiment. This makes the motor bracket 140 and the two motor glands high in strength, corrosion-resistant, and high-temperature-resistant, thereby ensuring the operational reliability of the motor assembly 150.

[0036] In a preferred embodiment, the air conditioner indoor unit 100 may further include rubber members disposed on the left and right end surfaces 131, 132 of the motor body 130, contacting the motor bracket 140 and the motor gland to reduce vibration and noise. Specifically, when the motor body 130 is operating, i.e., when driving the fan 112, vibration and noise are often generated. The provision of the rubber members can effectively reduce vibration and noise.

[0037] In a specific embodiment, the air conditioner indoor unit 100 may further include a frame 161 disposed in the cavity 113, and the motor assembly 150, which is fixed as an integral unit, is connected and fixed to the side of the frame 161. In other words, the motor body 130, the motor bracket 140, and the two motor glands may be first assembled into the integral motor assembly 150, and then the motor assembly 150 is connected to the frame 161. Figure 3 The illustrated situation is that the motor assembly 150 is disposed on the right side of the cavity 113 , and the motor assembly 150 is connected and fixed to the right side of the skeleton 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 glands can be similar to that described above, except that the overall arrangement is bilaterally symmetrical to the case where the motor assembly 150 is disposed on the right side of the cavity 113.

[0039] In a specific embodiment, the fan 112 is screwed to the rotating shaft 135 of the motor body 130 so that the rotating shaft 135 rotates to drive the fan 112 to rotate. More specifically, the fan 112 may have a screw hole, through which a screw is passed to fix the fan 112 to the rotating shaft 135 of the motor body 130. Figures 3 to 5 The fan 112 shown is only a portion of the complete structure, extending from the left side to the right side of the cavity 113. The motor body 130 is fixed to the fan 112, which effectively fixes the assembled motor assembly 150 and the fan 112 as a whole, thus facilitating the assembly and disassembly of the motor assembly 150 and the fan 112.

[0040] Figure 7 FIG. 1 is a side sectional view of a housing 110 of an air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 8 This is an exploded schematic diagram of an air conditioner indoor unit 100 embedded in a cabinet according to one 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. The panel 120 may have an air inlet 121 at its top and an air outlet 122 at its bottom. Air may enter the housing 110 through the air inlet 121, undergo heat exchange in the indoor heat exchanger 111, and then be discharged to the indoor environment through the air outlet 122.

[0041] In a specific embodiment, Figure 7 As shown, the interior of the housing 110 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. In fact, the air inlet of the first channel 115 and the air inlet of the second channel 116 are both part of the air inlet 121. In other words, the air entering the interior of the housing 110 through the air inlet 121 flows partially through the first channel 115 and partially through the second channel 116.

[0042] In addition, an indoor heat exchanger 111 is provided in each of the first channel 115 and the second channel 116. In a specific embodiment, Figure 4 As shown, the indoor heat exchanger 111 is arranged in sections 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. Generally, most of the air entering the housing 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 air volume and, in turn, cause adverse phenomena such as icing on the indoor heat exchanger 111. However, this embodiment provides two channels within the housing 110 and makes the air intake of the first channel 115 stronger than that of the second channel 116. This allows more air to 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 on the indoor heat exchanger 111 caused by insufficient air volume.

[0044] In a specific embodiment, Figure 7 As shown, a fan 112 may be provided below the indoor heat exchanger 111, configured to blow the air 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 basically set in a vertical state, the middle heat exchanger 118 can be set gradually higher from front to back, and the rear heat exchanger 119 can be set gradually lowered from front to back, so that the front heat exchanger 117, the middle heat exchanger 118 and the rear heat exchanger 119 jointly define a space below which the fan 112 is accommodated.

[0045] Furthermore, the airflow into the first channel 115 can be stronger than that into the second channel 116 by specifically configuring the fan 112. For example, the suction port of the fan 112 can be adjusted to be more directed toward the rear heat exchanger 119, so that the airflow into the first channel 115 is stronger than that into the second channel 116. Alternatively, in other embodiments, the fan 112 can be adjusted in other ways to achieve a stronger airflow into the first channel 115 than into the second channel 116.

[0046] like Figure 8 As shown, the air conditioner indoor unit 100 can be installed in a cabinet 200 having a forward opening 210, with the panel 120 facing forward. Specifically, a storage space 220 can be defined within the cabinet 200, and the air conditioner indoor unit 100 can be installed in the storage space 220. In one specific embodiment, the air conditioner indoor unit 100 can be placed directly in the storage space 220. In other embodiments, the air conditioner indoor unit 100 can be secured to the cabinet 200 by other means, such as by securing the housing 110 of the air conditioner indoor unit 100 to the cabinet 200, to enhance overall stability.

[0047] It's important to note that the current air intake system for flush-mounted air conditioner indoor units is not suitable. This is because traditional wall-mounted units typically draw air through a top air inlet. When the unit is embedded in a cabinet, the top is blocked by the cabinet, limiting air flow. Furthermore, the reduced air intake prevents the indoor heat exchanger from fully exchanging heat, leading to icing and affecting its proper function.

[0048] The air conditioner indoor unit 100 of this embodiment adopts a front-intake and front-outlet configuration, and employs a dual-channel solution within the housing 110. This allows sufficient air entering the housing 110 through the air inlet 121 to be directed to the rear heat exchanger 119 at the rear, thereby preventing ice formation on the indoor heat exchanger 111 due to insufficient air volume. Furthermore, the front-intake and front-outlet configuration is achieved without being restricted by the cabinet 200.

[0049] In a preferred embodiment, Figure 8 As shown, the air inlet 121 is provided with a rotatable plate 123. Moreover, 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 a specific embodiment, the rotatable plate 123 can be driven to rotate by a motor and a connecting rod mechanism 125. When the motor drives the connecting rod mechanism 125 to open the rotatable plate 123, the air inlet 121 opens; when the motor drives the connecting rod mechanism 125 to retract the rotatable plate 123, the air inlet 121 closes. Moreover, when the motor drives the connecting rod mechanism 125 to open the rotatable plate 123, the rotation angle of the rotatable plate 123 is different, and the opening area of the air inlet 121 is also different. In a specific embodiment, a filter 124 can also be provided at the air inlet 121 for preliminarily filtering the air entering the interior of the housing 110 from the air inlet 121 to prevent excessive dust and other impurities from entering the cavity 113.

[0050] The air conditioner indoor unit 100 of this embodiment is designed as a two-part, front and rear section consisting of a panel 120 and a housing 110. This facilitates both assembly and maintenance. Specifically, during assembly, the rear section of the housing 110 and its associated components can be installed into the cabinet 200 first, followed by the front section of the panel 120 and its associated components. This allows for easy maintenance of the rear section of the housing 110 while the front section of the panel 120 is open. Furthermore, after the panel 120 and housing 110 are assembled, the rear section of the housing 110 is not visible and is not a cosmetic component, thus reducing requirements and significantly reducing costs.

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

[0052] A water pan 162 can be provided below the indoor heat exchanger 111 to receive and accommodate condensed water generated by the indoor heat exchanger 111. By simply removing the water pan 162 and related front components such as the panel 120, the motor assembly 150 and fan 112 can be exposed, allowing for convenient disassembly and maintenance without having to disassemble the entire air conditioner indoor unit 100, effectively improving maintenance convenience.

[0053] When the air conditioner indoor unit 100 operates in cooling mode, the air heated by the indoor heat exchanger 111 is cold air, which is sent to the indoor environment through the air outlet 122 to reduce the temperature of the indoor environment, making the user feel cool. When the air conditioner indoor unit 100 operates in heating mode, the air heated by the indoor heat exchanger 111 is hot air, which is sent to the indoor environment through the air outlet 122 to increase the temperature of the indoor environment, making the user feel warm.

[0054] In a specific embodiment, the air conditioner indoor unit 100 can activate the cooling mode or the heating mode after receiving a user's activation trigger signal. More specifically, the activation trigger signal can be received from the user via a display device, a voice device, a remote control, or a mobile terminal associated with the air conditioner indoor unit 100. The mobile terminal can be a portable smart device, such as a smartphone or tablet computer.

[0055] The fan 112 can deliver the air heated by the indoor heat exchanger 111 to the indoor environment through the air outlet 122. The fan 112 in this embodiment is a cross-flow fan, which can also be called a cross-flow fan. The airflow enters the blades radially from the opening of the impeller, passes through the interior of the impeller, and is discharged into the volute from the blades on the other side, forming the working airflow. The airflow in an axial flow fan flows axially within the impeller. The air volume and wind speed of the fan 112 can be adjusted by adjusting the speed of the motor body 130, thereby adjusting the air supply effect of the air conditioner indoor unit 100.

[0056] In a specific embodiment, the air outlet 122 may also be provided with a guide plate 126 and a swing blade 127. The swing blade 127 may be configured to adjust the direction of air flow from the air outlet 122. In a specific embodiment, the swing blade 127 may be configured to adjust its specific position according to the air supply mode. For example, the air supply mode may include multiple different air supply instructions, and the swing blade 127 may adjust its specific position according to different air supply instructions. The guide plate 126 may 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 swing blade 127 can be delivered to the indoor environment. If the guide plate 126 closes the air outlet 122, no air will be blown out of the air outlet 122. Generally, when the air conditioner indoor unit 100 is turned off, the guide plate 126 may be used to 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 air conditioner indoor unit 100 of this embodiment includes: a shell 110, which defines a cavity 113 therein; an indoor heat exchanger 111, which is arranged in the cavity 113 and is configured to exchange heat with the air entering the cavity 113; a fan 112, which is arranged below the indoor heat exchanger 111 and is configured to blow out the air that has exchanged heat through the indoor heat exchanger 111; a motor assembly 150, which includes a motor body 130, a motor bracket 140 and two motor glands, wherein the motor body 130 is connected to the fan 112 and is configured to drive the fan 112 to rotate, the motor bracket 140 is mounted on the outside of the motor body 130, and the two motor glands are respectively pressed on the left end surface 131 and the right end surface 132 of the motor body 130. This can provide an air conditioner indoor unit 100 that is easy to disassemble and assemble motor components, saving time and energy of users or maintenance personnel, reducing maintenance costs, and improving convenience.

[0058] Furthermore, in the air conditioner indoor unit 100 of this embodiment, a first channel 115 and a second channel 116 are defined inside the housing 110. 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 provided in sections and includes, from front to back, a front heat exchanger 117, a middle heat exchanger 118, and a rear heat exchanger 119. 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 provided 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 exchanges heat through the rear heat exchanger 119.
