Detailed Implementation

[0032] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0033] In this application, the indoor unit of the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0034] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0035] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the indoor unit of the air conditioner regulates the temperature of the indoor space.

[0036] The outdoor unit of an air conditioner indoor unit refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner indoor unit includes the indoor heat exchanger, and the expansion valve can be provided in either the indoor unit or the outdoor unit.

[0037] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the indoor unit of the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the indoor unit of the air conditioner functions as a cooler in cooling mode.

[0038] The following is for reference. Figures 1-10 The air conditioner indoor unit 10 according to an embodiment of the present utility model includes: a housing 100, a heat exchanger, a fan, and an air duct.

[0039] Specifically, the housing 100 is provided with an air outlet and an air inlet. The air inlet is used to introduce airflow and discharge it through the air outlet. A heat exchanger is located within the housing space and is used to exchange heat with the passing refrigerant. A fan is arranged opposite to the heat exchanger and is used to drive the airflow through the heat exchanger for heat exchange. The two ends of the air duct are connected to the air inlet and the air outlet, respectively. The fan is located inside the air duct, and the air duct is configured to guide airflow. The housing 100 includes a housing body 110 and a panel 120. The housing body 110 is provided with an air outlet. One end of the panel 120 is rotatably connected to the housing body 110 and covers the air outlet. A connection is provided between the housing body 110 and the panel 120. Component 130, the connecting component 130 is used to open or close the air outlet; wherein, the connecting component 130 includes: a first connecting part 131 and a second connecting part 132, one end of the first connecting part 131 and one end of the second connecting part 132 overlap and are rotatably connected at the connection point, and the other end of the first connecting part 131 is rotatably connected to the housing body 110, and the other end of the second connecting part 132 is rotatably connected to the panel 120; when the connecting component 130 closes the air outlet, the first connecting part 131 and the second connecting part 132 extend in the same direction based on the connection point; when the connecting component 130 opens the air outlet, the first connecting part 131 and the second connecting part 132 extend in opposite directions based on the connection point.

[0040] It is understood that, in specific embodiments, the indoor unit 10 of the air conditioner is suitable to include: a housing 100, a heat exchanger, a fan, and an air duct. The housing 100 is suitable to provide protection for the electrical structures housed within the housing, and an air inlet and an air outlet are suitable to be constructed on the housing. The air inlet is suitable for introducing airflow, and the air outlet is suitable for discharging airflow. In this way, during the use of the indoor unit of the air conditioner, indoor airflow is introduced through the air inlet for processing, and the processed airflow is suitable to return to the indoor environment through the air outlet to improve the indoor environmental quality. A heat exchanger is suitable to be arranged within the housing, and the heat exchanger is suitable to exchange heat with the airflow passing through it, so that the processed airflow is suitable to act on the indoor environment through the air outlet. During the circulation of airflow, the fan is suitable to provide a driving force to drive the airflow. Similarly, the air duct is suitable to provide a restrictive function, so that the airflow introduced into the housing is suitable to flow under the guidance of the air duct, so that the airflow within the indoor unit of the air conditioner can flow according to the design, avoiding the generation of turbulence and noise during airflow, making the use of the air conditioner quieter, thereby improving the comfort of using the air conditioner.

[0041] Specifically, the housing 100 is adapted to include a housing body 110 and a panel 120, with the panel 120 disposed on the housing body 110. An air outlet is constructed on the housing body 110, allowing the panel 120 to be rotated to adjust the degree of obstruction of the air outlet by the panel 120. Furthermore, in actual use, a connecting component 130 is adapted to be provided between the housing body 110 and the panel 120, so that the connecting component 130 can adjust the usage of the panel 120, and enable the connecting component 130 to open or close the air outlet.

[0042] In some specific embodiments, the connecting component 130 is adapted to include a first connecting portion 131 and a second connecting portion 132. The first connecting portion 131 is adapted to be rotatably connected to the second connecting portion 132. Since the other end of the first connecting portion 131 is connected to the housing body 110 and the other end of the second connecting portion 132 is connected to the panel 120, the panel 120 is adapted to be connected through the first connecting portion 131 and the second connecting portion 132 after being opened. The first connecting portion 131 and the second connecting portion 132 are adapted to be supported between the panel 120 and the housing body 110, so that the panel 120 is adapted to be opened for assembly or maintenance. After use, the opening function of the panel 120 to the air outlet is released by releasing the supporting role of the first connecting portion 131 and the second connecting portion 132, so that the panel 120 can be closed to block the air outlet.

[0043] In other words, in this application, when the housing 100 is opened to assemble the indoor unit 10 of the air conditioner, or when the housing 100 is opened to repair the indoor unit 10 of the air conditioner, it is appropriate to open the housing 100 to expose the electrical components, and then support the panel 120 by the connecting component 130 so that the user can repair and disassemble the structure inside the housing 100. After the repair, disassembly and maintenance are completed, it is appropriate to release the supporting function of the connecting component 130 so that the panel 120 can return to the housing body 110 and be connected, so that the housing 100 can form a complete structure to protect the structure inside it.

[0044] In practical use, when assembling the indoor unit 10 of the air conditioner by opening the housing 100, or when repairing the indoor unit 10 of the air conditioner by opening the housing 100, the housing 100 is provided with a first limiting part and a second limiting part that mutually limit each other. When the panel 120 is closed on the housing body 110, the connecting component 130 provides a limiting effect. When it is necessary to open the connecting component 130, the unlocked panel 120 can be opened, exposing the space inside the housing 100, so as to facilitate the assembly of other structures inside the housing 100, or the maintenance and repair of other structures, thereby extending the service life of the indoor unit 10 of the air conditioner. Furthermore, after assembling or repairing the indoor unit 10 of the air conditioner, it is suitable to rotate the panel 120, so that the second limiting part on the panel 120 engages with the first limiting part on the housing body 110, so that the panel 120 can be supported and locked on the housing body 110.

[0045] For example, the connecting assembly 130 has multiple usage states, including a first usage state and a second usage state. When the connecting assembly 130 is in the first usage state, it is adapted to fix the panel 120 to confine the panel 120 to the housing body 110. When the connecting assembly 130 is in the second usage state, it is adapted to provide support to open and support the panel 120, so as to facilitate the maintenance and repair of the air conditioner indoor unit 10 and improve the performance and service life of the air conditioner indoor unit 10.

[0046] In some embodiments, the connecting assembly 130 includes: a first connecting portion 131 and a second connecting portion 132. One end of the first connecting portion 131 is provided with a first connecting hole 1311, and the first connecting portion 131 is rotatably connected to the housing body 110 through the first connecting hole 1311. One end of the second connecting portion 132 is provided with a second connecting hole 1321, and the second connecting portion 132 is rotatably connected to the panel 120 through the second connecting hole 1321. The other end of the first connecting portion 131 is rotatably connected to the other end of the second connecting portion 132. The second connecting portion 132 can rotate relative to the first connecting portion 131. When the extension direction of the second connecting portion 132 is the same as the extension direction of the first connecting portion 131, the connecting assembly 130 is in a first use state. When the extension direction of the second connecting portion 132 is opposite to the extension direction of the first connecting portion 131, the connecting assembly 130 is in a second use state.

[0047] In other words, in a specific embodiment, the connecting component 130 is adapted to include a first connecting portion 131 and a second connecting portion 132. The first connecting portion 131 is adapted to be rotatably connected to the housing body 110, and the second connecting portion 132 is adapted to be rotatably connected to the panel 120. Thus, during use, when the connecting component 130 is needed to restrict the housing body 110 and the panel 120, it is suitable to place the first connecting portion 131 and the second connecting portion 132 in the same extending direction, so that the second connecting portion 132 can pull the panel 120 onto the housing body 110. Furthermore, by maintaining the first connecting portion 131 and the second connecting portion 132 in their current usage state, the connecting component 130 can still provide a good restrictive function. When the connecting component 130 is needed to support the panel 120, the second connecting part 132 is adapted to rotate and open relative to the first connecting part 131, so that the first connecting part 131 and the second connecting part 132 extend in opposite directions, thereby allowing the first connecting part 131 and the second connecting part 132 to play a supporting role, so that the panel 120 is supported and opened, thereby making the receiving space 101 inside the housing 100 suitable for opening, so that the structure inside the receiving space 101 is suitable for opening, so as to facilitate maintenance and other procedures for the air conditioner indoor unit 10, thereby improving the performance and service life of the air conditioner indoor unit 10.

[0048] According to an embodiment of the present invention, the indoor unit 10 of the air conditioner includes a connecting component 130 between the housing body 110 and the panel 120. The connecting component 130 has multiple usage states, allowing it to both restrict the position of the housing body 110 and the panel 120 and support the panel 120 for ease of maintenance. Furthermore, since a first connecting portion 131 is connected to the housing body 110 and a second connecting portion 132 is connected to the panel 120, the connecting component 130 is positioned between the housing body 110 and the panel 120 by rotating the first connecting portion 131 and the second connecting portion 132. In this way, during the use of the indoor unit 10, the usage status of the first connecting part 131 and the second connecting part 132 can be adjusted as needed, so that the indoor unit 10 can be supported or restricted by the connecting component 130 during assembly and maintenance, thereby improving work efficiency, enhancing the subsequent performance and service life of the indoor unit 10, and improving the structural stability of the panel 120 set on the housing body 110, thereby enhancing the performance of the indoor unit 10.

[0049] In some embodiments, the length of the first connecting portion 131 is A, and the length of the second connecting portion 132 is B, where lengths A and B satisfy the relationship: B < A. It is understood that setting the length of the second connecting portion 132 to be less than the length of the first connecting portion 131 serves two purposes: firstly, the first connecting portion 131 is located outside the second connecting portion 132 to protect it; secondly, the distance from the connection point of the second connecting portion 132 to the panel 120 to the other end of the second connecting portion 132 is less than the distance from the connection point of the first connecting portion 131 to the housing body 110 to the first connecting portion 131. This allows the connecting assembly 130 to support and constrain the panel 120 as designed during use, making the structure of the housing 100 more reliable.

[0050] In some embodiments, the connecting assembly 130 further includes a mounting base 133, on which a rotating shaft 134 is provided. The connection points of the first connecting portion 131 and the second connecting portion 132 are correspondingly located on the rotating shaft 134 and rotate relative to the rotating shaft 134 to open or close the air outlet. It is understood that the rotating shaft 134 on the mounting base 133 provides a rotation center for the rotation of the first connecting portion 131 and the second connecting portion 132, allowing the first connecting portion 131 and the second connecting portion 132 to rotate around the rotating shaft 134. This allows the connecting assembly 130 to be used as designed, enabling the connecting assembly 130 to restrict and support the panel 120. Furthermore, the mounting base 133 is adapted to be disposed outside the first connecting portion 131 and the second connecting portion 132, so that the mounting base 133 is suitable for protecting the connection points of the first connecting portion 131 and the second connecting portion 132, thereby improving the performance and service life of the connecting assembly 130.

[0051] In some embodiments, the mounting base 133 further includes a connecting groove 1331, on which the rotating shaft 134 is mounted, and at least a portion of the first connecting portion 131 and at least a portion of the second connecting portion 132 are disposed within the connecting groove 1331. It is understood that the connecting groove 1331 is adapted to provide installation space for the rotating shaft 134, allowing the connection point of the first connecting portion 131 and the second connecting portion 132 to be arranged within the connecting groove 1331. This allows the mounting base 133 to better protect the connecting assembly 130, thereby enabling the connecting assembly 130 to provide more reliable constraint and support for the panel 120, thus improving the reliability of the air conditioner indoor unit 10.

[0052] In some embodiments, a limiting piece 1332 is provided on one side of the mounting base 133. The limiting piece 1332 is located at the bottom of the connecting groove 1331 and is disposed opposite to the first connecting portion 131. The limiting piece 1332 is used to limit the rotation angle of the first connecting portion 131. That is, the limiting piece 1332 is provided on one side of the mounting base 133. Since the limiting piece 1332 can be disposed opposite to the first connecting portion 131, the limiting piece 1332 can protect the first connecting portion 131 and prevent the connecting assembly 130 from rotating excessively. This allows the connecting assembly 130 to rotate according to the design to limit or support the panel 120, making it easier to repair and maintain the indoor unit 10, thereby improving the performance and service life of the indoor unit 10.

[0053] In some embodiments, an elastic piece 1333 is further provided on one side of the mounting base 133. The elastic piece 1333 is located at the bottom of the connecting groove 1331, and is spaced apart from the limiting piece 1332. The elastic piece 1333 is disposed opposite to the second connecting portion 132, and is used to limit the rotation angle of the second connecting portion 132. In this way, the elastic piece 1333 is adapted to be disposed opposite to the second connecting portion 132, so that the elastic piece 1333 is suitable for protecting the second connecting portion 132. At the same time, the elastic piece 1333 provided on the mounting base 133 is adapted to have a certain elasticity, so that the elastic piece 1333 can drive the second connecting portion 132 to reset to avoid excessive rotation, thereby improving the reliability of the connecting assembly 130 during use.

[0054] In some embodiments, a limiting baffle 150 is also provided on the other side of the mounting base 133. The limiting baffle 150 is located at the bottom of the connecting groove 1331 and is symmetrically arranged with the elastic sheet 1333. The limiting baffle 150 is used to limit the rotation angle of the second connecting part 132. That is, a limiting baffle 150 is also provided on the other side of the mounting base 133. The limiting baffle 150 is adapted to be constructed at the bottom of the connecting groove 1331 so that the rotation angle of the second connecting part 132 is limited by the limiting baffle 150 during rotation, so as to avoid excessive rotation of the second connecting part 132, which would affect the use of the second connecting part 132. This allows the connecting assembly 30 to be used according to the control during use, and the use of the panel 120 can be adjusted according to the user's control, making the use of the panel 120 simpler and more convenient, thereby simplifying the use and control of the air conditioner indoor unit 10.

[0055] In some embodiments, the first connecting portion 131 and the mounting base 133 are integrally formed. It is understood that making the first connecting portion 131 and the mounting base 133 integrally formed saves production steps for the connecting assembly 130, simplifies the production process of the first connecting portion 131 and the mounting base 133, improves the connection strength between the first connecting portion 131 and the mounting base 133, increases the structural strength of the connecting assembly 130, and allows the connecting assembly 130 to be used as designed, thereby improving the reliability and ease of use of the air conditioner indoor unit 10.

[0056] In some embodiments, both the ends of the first connecting portion 131 and the second connecting portion 132 have arc segments 140. In this way, by having arc segments 140 at the ends of both the first connecting portion 131 and the second connecting portion 132, the connecting assembly 130 is suitable for driving the first connecting portion 131 and the second connecting portion 132 to rotate during use. Setting the ends as arc segments 140 avoids the possibility of interference between the first connecting portion 131 and the second connecting portion 132 and the mounting base 133, as well as the housing body 110 and the panel 120 during rotation, thus ensuring higher reliability of the connecting assembly 130 and allowing it to be used as designed, thereby improving the subsequent ease of use of the air conditioner indoor unit 10.

[0057] In some embodiments, the panel 120 is provided with a first fixing seat 121, the first fixing seat 121 is provided with a rotating column 122, and the second connecting part 132 is rotatably connected to the rotating column 122; the housing body 110 is provided with a second fixing seat 111, the second fixing seat 111 is provided with a fixing column 112, and the first connecting part 131 is rotatably connected to the fixing column 112.

[0058] To facilitate the installation of the first connecting part 131, a first fixing seat 121 can be constructed on the panel 120, and a rotating column 122 can be constructed on the first fixing seat 121. This allows the second connecting part 132 to be rotatably connected to the rotating column 122, enabling the second connecting part 132 to rotate during use through its connection with the rotating column 122, thus providing support and positional limitation for the connecting assembly 130. Similarly, to facilitate the installation and use of the first connecting part 131, a second fixing seat 111 can be constructed on the housing body 110, and a fixing column 112 can be constructed on the second fixing seat 111. This allows the second connecting part 132 to be rotatably connected to the housing body 110 during assembly. In this way, the first connecting part 131 and the second connecting part 132 can be connected to the panel 120 and the housing body 110 by rotation during use, so that the connecting component 130 can be used as designed to support or restrict the panel 120 and the housing body 110, making the assembly, use and maintenance of the air conditioner indoor unit 10 simpler and more convenient, thereby improving its service life and performance.

[0059] According to an embodiment of the present invention, the indoor unit 10 of the air conditioner has an air outlet and an air inlet on the housing 100. The air inlet is used to introduce airflow and discharge it through the air outlet. A heat exchanger is disposed in the housing space and is used to exchange heat with the refrigerant passing through it. A fan is disposed opposite to the heat exchanger and is used to drive the airflow through the heat exchanger for heat exchange. The two ends of the air duct are respectively connected to the air inlet and the air outlet. The fan is disposed in the air duct and the air duct is configured to guide the airflow. The housing 100 includes a housing body 110 and a panel 120. The housing body 110 has an air outlet. One end of the panel 120 is rotatably connected to the housing body 110 and the panel 120 covers the air outlet. A connecting component 130 is provided between the housing body 110 and the panel 120. The connecting component 130 is used to open or close the air outlet.

[0060] It is understood that, in specific embodiments, the air conditioner indoor unit 10 is adapted to include: a housing 100, a heat exchanger, a fan, and an air duct. The housing 100 is adapted to provide protection for the electrical structures housed within it, and an air inlet and an air outlet are adapted to be constructed on the housing 100. The air inlet is adapted to introduce airflow, and the air outlet is adapted to discharge airflow. In this way, during the use of the air conditioner indoor unit 10, indoor airflow is adapted to be introduced through the air inlet for processing, and the processed airflow is adapted to return to the indoor environment through the air outlet to improve the indoor environmental quality. A heat exchanger is suitable for being arranged inside the casing 100. The heat exchanger is suitable for exchanging heat with the airflow passing through it, so that the treated airflow can be used to act on the indoor environment through the air outlet. During the circulation of the airflow, a fan is suitable for providing a drive to drive the airflow. Similarly, the air duct is suitable for providing a restrictive function, so that the airflow introduced into the casing 100 can be guided by the air duct. Thus, the airflow in the indoor unit 10 of the air conditioner can be circulated according to the design, avoiding the generation of eddies and noise during the airflow process, making the air conditioner quieter to use, thereby improving the comfort of using the air conditioner.

[0061] In this application, when assembling the indoor unit 10 of the air conditioner after opening the housing 100, or when opening the housing 100 to repair the indoor unit 10, it is suitable to open the housing 100 and support the panel 120 through the connecting components, so that the user can repair and disassemble the structure inside the housing 100. After the repair, disassembly and maintenance are completed, it is suitable to release the supporting function of the connecting components 130 so that the panel 120 can return to the housing body 110 and be connected, so that the housing 100 can form a complete structure to protect the structure housed therein.

[0062] Specifically, the connecting component 130 has multiple usage states, including a first usage state and a second usage state. When the connecting component 130 is in the first usage state, it is adapted to fix the panel 120, thereby confining the panel 120 to the housing body 110. When the connecting component 130 is in the second usage state, it is adapted to provide support to open and support the panel 120, thereby facilitating the maintenance and repair of the indoor unit 10 and improving its performance and service life.

[0063] According to an embodiment of the present invention, the indoor unit 10 of the air conditioner includes a connecting component 130 between the housing body 110 and the panel 120. The connecting component 130 has multiple usage states, allowing it to both restrict the position of the housing body 110 and the panel 120 and support the panel 120 for ease of maintenance. Furthermore, since a first connecting portion 131 is connected to the housing body 110 and a second connecting portion 132 is connected to the panel 120, the connecting component 130 is positioned between the housing body 110 and the panel 120 by rotating the first connecting portion 131 and the second connecting portion 132. In this way, during the use of the indoor unit 10, the usage status of the first connecting part 131 and the second connecting part 132 can be adjusted as needed, so that the indoor unit 10 can be supported or restricted by the connecting component 130 during assembly and maintenance, thereby improving work efficiency, enhancing the subsequent performance and service life of the indoor unit 10, and improving the structural stability of the panel 120 set on the housing body 110, thereby enhancing the performance of the indoor unit 10.
