Detailed Implementation

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] The following is for reference. Figures 1-12 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.

[0041] Specifically, the housing 100 has a receiving space 101, and the housing 100 is configured to protect the structure located within it. The housing 100 has 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 receiving space 101 and is used to exchange heat with the passing refrigerant. A fan is positioned opposite the heat exchanger and drives the airflow through the heat exchanger for heat exchange. Two ends of an air duct are connected to the air inlet and air outlet, respectively. The fan is located within 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 100 has an air outlet, and one end of the panel 120 is rotatably connected to the housing body 110. The air outlet is obstructed. A limiting component 130 is provided between the housing body 110 and the panel 120. The housing body 110 and the panel 120 are locked and unlocked by the limiting component 130, and the limiting component 130 can switch between the locked state and the unlocked state. The limiting component 130 includes a first limiting part 111 and a second limiting part 121. The first limiting part 111 is provided on the housing body 110, and the second limiting part 121 is provided on the panel 120. The second limiting part 121 includes a slot 125. When the limiting component 130 is in the locked state, the free end of the first limiting part 111 is engaged in the slot 125. When the limiting component 130 is in the unlocked state, the free end of the first limiting part 111 is disengaged from the slot 125.

[0042] 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. 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 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 can flow under the guidance of the air duct. Thus, the airflow in the indoor unit of the air conditioner can flow according to the design, avoiding the generation of eddies and noise during the airflow process, making the air conditioner quieter and improving the comfort of using the air conditioner.

[0043] 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 rotate to adjust the degree of obstruction of the air outlet by the panel 120. Furthermore, in actual use, a limiting component 130 is adapted to be provided between the housing body 110 and the panel 120, so that the limiting component 130 can adjust the limiting use of the panel 120 on the housing body 110, thereby enabling the limiting component 130 to open or close the air outlet.

[0044] 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 suitable to press the housing 100. Since the housing 100 has an upper limit component 130, the limit component 130 is suitable to restrict the use of the panel 120. Specifically, the limit component 130 is suitable to include a first limit part 111 and a second limit part 121 that are mutually limit-fitting. When the panel 120 is closed on the housing body 110, it is suitable to press the places where the first limit part 111 and the second limit part 121 are limit-fitting, so that the pressing action can release the limit-fitting of the first limit part 111 and the second limit part 121, thereby allowing the unlocked panel 120 to be opened. The opened panel 120 can expose 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 and allow the second limiting part 121 on the panel 120 to engage with the first limiting part 111 on the housing body 110 to lock the panel 120 onto the housing body 110.

[0045] According to an embodiment of the present invention, the indoor unit 10 of the air conditioner has a limiting component 130 provided between the housing body 110 and the panel 120. This allows the panel 120 to be closed on the housing body 110 by the limiting component 130. During the opening of the panel 120, the limiting component 130 can be released to easily release the panel 120 from the housing body. Specifically, the limiting component includes a first limiting part 111 and a second limiting part 121. Since the first limiting part 111 and the second limiting part 121 can perform limiting cooperation, the assembly reliability of the housing 100 is improved. Furthermore, when it is necessary to open the panel 120, it is suitable to unlock the limiting connection between the first limiting part 111 and the second limiting part 121 to release the limiting engagement between the first limiting part 111 and the second limiting part 121, thereby releasing the connection restriction between the housing body 110 and the panel 120, simplifying the use and maintenance process of the air conditioner indoor unit 10, and thus extending the service life of the air conditioner indoor unit 10.

[0046] In some embodiments, there are two first limiting portions 111 arranged opposite to each other, and each first limiting portion 111 includes a latch 112. The latch 112 is located at the free end of the first limiting portion 111. The second limiting portion 121 includes a limiting post 122 and a limiting sleeve 123. The limiting sleeve 123 is sleeved on the limiting post 122. The free end of the limiting post 122 is provided with a limiting member 124. A groove 125 is formed between the limiting member 124 and the limiting sleeve 123. The latch 112 is engaged in the groove 125. In this way, during the assembly and positioning of the housing body 110 and the panel 120, a latch 112 is adapted to be constructed on the first limiting part 111, and a slot 125 is provided on the second limiting part 121, so that the latch 112 is correspondingly connected in the slot 125, thereby realizing the assembly restriction between the panel 120 and the housing body 110, thus giving the housing 100 a higher structural strength to protect the internal structure of the housing 100, thereby improving the reliability of the air conditioner indoor unit 10. Furthermore, when it is necessary to release the lock between the latch 112 and the slot 125, it is suitable to press the connection between the latch 112 and the slot 125 to release the connection restriction between the latch 112 and the slot 125, thereby releasing the connection restriction between the housing body 110 and the panel 120, allowing the panel 120 to be opened relative to the housing body 110, exposing the structures hidden inside the housing 100 for maintenance and repair. Specifically, the second limiting part 121 includes a limiting post 122 and a limiting sleeve 123, so that the limiting sleeve 123 is fitted onto the limiting post 122. Since the free end of the limiting post 122 is provided with a limiting member 124, a groove 125 can be formed between the limiting member 124, the limiting post 122, and the limiting sleeve 123 to achieve limiting engagement with the first limiting part 111. That is, in the specific implementation process, when the second limiting part 121 is pressed, it is suitable for the limiting member 124 of the second limiting part 121 to drive the limiting post 122 to move and enter into the first limiting part 111, so that a groove 125 can be formed on the second limiting part 121, so that the groove 125 can engage with the latch 112 to realize the assembly connection between the housing body 110 and the panel 120.When it is necessary to unlock the housing body 110 and the panel 120, it is appropriate to press the connection between the first limiting part 111 and the second limiting part 121 so that the second limiting part 121 can continue to move downward under the guidance of the limiting member 124. Then, due to the structural strength of the housing body 110, the housing body 110 is suitable to drive the limiting post 122 to move. Then, the limiting post 122 is suitable to drive the limiting member 124 and abut against the limiting sleeve 124. At this time, the limiting tongue 112 is locked on the outside of the limiting sleeve 123. Since the contact between the limiting sleeve 123 and the limiting member 124 is tighter, the limiting sleeve 123 can transmit the driving force to the limiting member 124 and make contact. This allows the first locking part to go directly to the outside of the second limiting part 121 through the limiting sleeve 123, so as to avoid interference between the first limiting part 111 and the second limiting post 122.

[0047] In some embodiments, a gap is provided between the limiting sleeve 123 and the limiting post 122, allowing the limiting sleeve 123 to slide relative to the limiting post 122. In this way, during actual use, the gap between the limiting sleeve 123 and the limiting post 122 allows the limiting sleeve 123 to slide relative to the limiting post 122, reducing interference loss during the sliding process. This reduces the impact on the installation and disassembly of the panel 120 and the housing body 110, thereby simplifying the assembly process for the user when assembling and disassembling the indoor unit 10 of the air conditioner.

[0048] In some embodiments, the inner diameter of the limiting sleeve 123 is A, the diameter of the limiting post 122 is B, and the cross-sectional width of the limiting member 124 facing the limiting post 122 is C. The inner diameter A, diameter B, and width C satisfy the relationship: B < A < C. It can be understood that the inner diameter of the limiting sleeve 123 is larger than the diameter of the limiting post 122 so that the limiting sleeve 123 can be fitted onto the outside of the limiting post 122 and can slide relative to the limiting post 122, thereby constituting the assembly, limiting, and disassembly process of the first limiting part 111 and the second limiting part 121. The cross-sectional diameter of the limiting member 124 is larger than that of the limiting sleeve 123, so that the limiting sleeve 123 can better resist and restrict the limiting member 124 for use. This allows the limiting member 124 to drive the limiting sleeve 123 to move according to the design, making the unlocking process between the housing body 110 and the panel 120 more reliable, and making the assembly and disassembly of the housing 100 more reliable.

[0049] In some embodiments, the length of the limiting sleeve 123 is D, and the length of the limiting post 122 is E, with lengths D and E satisfying the relationship: D < E. This allows the limiting sleeve 123 to be shorter than the length of the limiting post 122, enabling the limiting sleeve 123 to move along the length of the limiting post 122. This allows the limiting sleeve 123 to form a slot 125 to engage and unlock the latch 112, simplifying the assembly and disassembly process between the housing body 110 and the panel 120, and making the maintenance and repair of the air conditioner indoor unit 10 easier.

[0050] In some embodiments, the side of the limiting member 124 facing the limiting sleeve 123 is a contact surface, which is flat, and the limiting sleeve 123 can abut against the contact surface. It is understood that setting the side of the limiting member 124 facing the limiting sleeve 123 as a contact surface, and setting the contact surface as flat, makes the contact between the limiting sleeve 123 and the contact surface more reliable. This allows the limiting member 124 to drive the limiting sleeve 123 to move as designed, thereby unlocking the housing body 110 and the panel 120. This makes the disassembly, maintenance, and repair of the air conditioner indoor unit 10 simpler and more convenient, improving the performance and service life of the air conditioner indoor unit 10.

[0051] In some embodiments, the cross-sectional width of the limiting member 124 is semi-circular. This semi-circular cross-section of the limiting member 124 allows it to both restrict and drive the limiting sleeve 123 while also providing good guiding performance. This ensures that when the housing body 110 and panel 120 are pressed to unlock, the limiting member 124 can better guide and drive the latch 112 onto the limiting sleeve 123, thus enabling the unlocking process of the first limiting portion 111 and the second limiting portion 121. In other embodiments, the first limiting portion 111 is provided with an arc-shaped guide surface, allowing the guide surface to guide and engage with the limiting member 124. This simplifies the subsequent unlocking process between the first limiting portion 111 and the second limiting portion 121, allowing them to unlock as designed, thus simplifying the disassembly of the housing 100.

[0052] In some specific embodiments, a reset member 127 is also provided inside the limiting sleeve 123. One end of the reset member 127 is connected to the limiting sleeve 123, and the other end of the reset member 127 is connected to the limiting post 122, so that the limiting sleeve 123 is suitable to be driven and reset by the reset member 127 during use, so that the position of the slot 125 can be displayed, thereby facilitating the latch 112 to engage in the slot 125, making the engagement between the first limiting part 111 and the second limiting part 121 more reliable. At the same time, the reset member 127 can also reset the position of the limiting sleeve 123, so as to facilitate subsequent reassembly and use.

[0053] In some embodiments, a guide portion 115 is provided on one side of the latch 112, the free end of the guide portion 115 is engaged in the slot 125, and the guide portion 115 is disposed opposite to the limiting sleeve 123. It can be understood that by providing a guide portion 115 on one side of the latch 112, the latch 112 is adapted to be engaged in the slot 125 through the guide portion 115, and the latch 112 can be disposed opposite to the limiting sleeve 123 using the guide portion 115. This allows the latch 112 to be arranged in the slot 125 for restriction as designed, thereby improving the assembly restriction effect of the latch 112 and improving the reliability of the panel 120 on the housing body 110.

[0054] In some embodiments, the first limiting part 111 includes a limiting block 113 and a spring piece 114. The limiting block 113 is slidably connected to the housing body 110. The limiting block 113 is provided with a latch 112. One end of the spring piece 114 is fixedly connected to the housing body 110, and the other end of the spring piece 114 is connected to the limiting block 113. It is understood that the limiting block 113 is adapted to slide, and a spring piece 114 is provided on one side of the limiting block 113. The spring piece 114 is adapted to move elastically. During the assembly process, it is adapted to allow the second limiting part 121 to abut against the first limiting part 111, and allow the limiting member 124 to drive the first limiting part 111 to move, so as to expose enough space for the second limiting part 121 to be assembled. Then the slot 125 on the second limiting part 121 is exposed, and then the spring piece 114 is compressed and provides a driving action to drive the limiting block 113 to move, so as to allow the latch 112 on the limiting block 113 to move and engage in the slot 125, so as to realize the fixed connection between the housing body 110 and the panel 120. When unlocking is required, the latch 112, which is adapted to be driven, moves so that the latch 112 can abut against the outside of the limiting sleeve 123. Then, it moves with the outer wall of the limiting sleeve 123 and acts on the outside of the limiting member 124 to unlock the first latching part and the second latching part. At the same time, the spring piece 114 is adapted to drive the limiting block 113 to move so that the position of the second latching part is reset, thereby facilitating the subsequent reassembly and connection of the housing body 110 and the panel 120.

[0055] In some embodiments, the cross-section of the latch 112 gradually decreases along the moving direction of the limiting block 113. That is, the cross-section of the latch 112 gradually decreases along the moving direction of the limiting block 113, so that the cross-section of the latch 112 can be constructed as an inclined surface, and the inclination angle of the inclined surface faces the outside of the air conditioner indoor unit 10. In this way, during the engagement of the first engagement part and the second engagement part, the inclined surface is suitable to provide a guiding function, so that the second engagement part can be assembled with the first engagement part more simply and efficiently according to the design, so that the engagement effect between the first engagement part and the second engagement part is more reliable, thereby simplifying the assembly process between the housing body 110 and the panel 120 and making the assembly more reliable, thereby improving the structural performance of the air conditioner indoor unit 10.

[0056] An indoor air conditioning unit 10 according to an embodiment of the present invention includes: a housing 100, a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. The housing 100 has a receiving space 101 and is used to connect to a wall-mounted panel. The housing 100 is configured to protect the structure located within it. The compressor is located within the receiving space 101 and is used to drive the refrigerant to compress and flow. The first heat exchanger is located within the receiving space 101 and is located at the output end of the compressor. The first heat exchanger is used to exchange heat with the passing refrigerant. The throttling device is connected to the output end of the first heat exchanger and is used to throttle and pressurize the passing refrigerant. The second heat exchanger is connected to the output end of the throttling device, and the other end of the second heat exchanger is connected to the air inlet end of the compressor. The second heat exchanger is used to exchange heat with the passing refrigerant. The housing 100 includes a housing body 110 and a panel 120, which are connected and unlocked by pressing.

[0057] It is understood that, in specific embodiments, the air conditioner indoor unit 10 is suitable to include: a housing 100, a compressor, a first heat exchanger, a throttling device, and a second heat exchanger. During the use of the air conditioner indoor unit 10, the compressor is suitable to provide driving force to drive the refrigerant to circulate, and the refrigerant is suitable for heat exchange. Depending on the usage of the air conditioner indoor unit 10, the refrigerant is introduced into the first or second heat exchanger to form a cooling or heating mode for the air conditioner indoor unit 10, allowing it to be used as designed to improve the indoor environment, thereby making the user experience of the air conditioner indoor unit 10 more comfortable. After passing through the throttling device, the refrigerant flows to the other of the first or second heat exchanger and then returns to the compressor to participate in subsequent cycles.

[0058] 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 suitable to press the housing 100. Since the housing 100 is provided with a first limiting part 111 and a second limiting part 121 that limit each other, when the panel 120 is closed on the housing body 110, it is suitable to press the places where the first limiting part 111 and the second limiting part 121 limit each other, so that the pressing action can release the limiting cooperation of the first limiting part 111 and the second limiting part 121, thereby allowing the unlocked panel 120 to be opened. The opened panel 120 can expose 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, so as to extend 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 and allow the second limiting part 121 on the panel 120 to engage with the first limiting part 111 on the housing body 110 to lock the panel 120 onto the housing body 110.

[0059] According to an embodiment of the present invention, the indoor unit 10 of the air conditioner has a first limiting part 111 and a second limiting part 121 provided between the housing body 110 and the panel 120. Since the first limiting part 111 and the second limiting part 121 can engage in a limiting cooperation, the assembly reliability of the housing 100 is improved. Furthermore, when it is necessary to open the panel 120, the limiting connection between the first limiting part 111 and the second limiting part 121 can be unlocked, allowing the first limiting part 111 and the second limiting part 121 to engage in a limiting engagement to restrict the connection between the housing body 110 and the panel 120. This simplifies the use and maintenance process of the indoor unit 10, thereby extending its service life.
