[0002] The lift panel of an air conditioner is an important component that combines functionality (airflow and dust prevention) with aesthetics.

[0003] In the existing technology, the lifting panel needs to be lifted and lowered under the action of the drive mechanism. However, while lifting and lowering the panel, it is necessary to ensure that the connection between the panel and the outer cover is reliable. A new design structure is needed to achieve lifting and lowering while the movable panel is connected to the outer cover. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide an indoor unit for an air conditioner, which has a vertically movable connecting rod on the front side of the casing, and a hook on the panel that is rotatably connected to a connecting post on the connecting rod. Thus, the panel can be moved up and down as the connecting rod moves up and down.

[0005] To achieve the above objectives, an indoor unit of an air conditioner is proposed according to an embodiment of the present invention, comprising: a casing, wherein an air inlet and an air outlet are provided on the casing; a fan assembly, wherein the fan assembly is disposed within the casing; an indoor heat exchanger, wherein the indoor heat exchanger is disposed within the casing, and the fan assembly is used to introduce airflow from outside the casing into the casing through the air inlet, and after heat exchange by the indoor heat exchanger, output it to the outside through the air outlet; characterized in that it further comprises: a panel, wherein the air outlet is located on the front side of the casing, and a vertically movable connecting rod is provided on the front side of the casing, the panel being connected to the connecting rod and moving up and down with the connecting rod to open and close the air outlet; wherein the panel is provided with a hook, and the connecting rod is provided with a connecting post, the hook being rotatably hooked to the connecting post, and the panel being rotatable relative to the connecting rod towards the front and upward.

[0006] The above technical solution has the following advantages or beneficial effects: by setting a vertically movable connecting rod on the front side of the housing and setting a hook on the panel, and making the hook rotatably connected to the connecting post on the connecting rod, the panel can be driven to move up and down during the vertical movement of the connecting rod. The hook and connecting post in this utility model have a simple structure and reliable connection. This not only reduces the assembly difficulty of the panel and the housing, but also enables the panel to move up and down on the front side of the housing.

[0007] According to some embodiments of this utility model, the connecting column is provided with an anti-slip groove.

[0008] The above technical solution has the following advantages or beneficial effects: On the one hand, the anti-slip groove has a simple structure and is easy to process, which can simplify the production process of the connecting rod. On the other hand, the anti-slip groove can increase the friction between the hook and the connecting column, so that when the panel moves up and down with the support, it can ensure the stable cooperation between the panel and the connecting rod and prevent the panel from slipping. This can improve the stability of the panel when it is raised and lowered, thereby improving the safety of the panel when it is raised and lowered.

[0009] According to some embodiments of the present invention, there are multiple anti-slip grooves, and the multiple anti-slip grooves are spaced apart on the connecting column.

[0010] The above technical solution has the following advantages or beneficial effects: it can increase the friction between the surface of the connecting column and the surface of the hook, so that when the panel moves up and down with the support, it can further ensure the stable cooperation between the panel and the connecting rod and prevent the panel from slipping.

[0012] The above technical solution has the following advantages or beneficial effects: it allows the upper part of the panel to be connected to the housing, and enables the panel to rotate forward and upward. If the connecting post is placed at the lower end of the connecting rod, the panel cannot rotate forward and upward, but can only rotate forward and downward. Although this allows the panel to be opened, it is not convenient to clean the filter. Compared with the solution where the connecting post is placed at the lower end of the connecting rod, placing the connecting post at the upper end of the connecting rod is more convenient to operate.

[0013] According to some embodiments of this utility model, the hook is provided with a first reinforcing rib.

[0014] The above technical solution has the following advantages or beneficial effects: the first reinforcing rib can strengthen the structural strength of the hook, and can make the hook connection between the hook and the connecting column meet the load-bearing requirements of the hook on the panel, so as to ensure the reliability of the connection between the panel and the hook.

[0015] According to some embodiments of the present invention, the end of the hook is provided with a first guide slope, which selectively guides and engages with the connecting post.

[0016] The above technical solution has the following advantages or beneficial effects: A first guide slope is provided on the connecting surface of the hook and the connection point. The first guide slope is an inclined surface. The inclined surface is set to cooperate with the surface of the connecting column, so that the connecting column can slide into the hook quickly, so that the panel and the connecting rod can be quickly connected. This can improve the installation convenience and installation efficiency of the panel and the front side of the housing.

[0017] According to some embodiments of the present invention, a first abutting part is provided on the panel, and a second abutting part is provided on the connecting rod. One of the first abutting part and the second abutting part is an abutting groove, and the other is an abutting protrusion. The abutting protrusion and the abutting groove selectively abut and cooperate.

[0018] The above technical solution has the following advantages or beneficial effects: the abutting groove and the abutting protrusion have a reliable abutting fit. This setting can increase the limit between the panel and the connecting rod, and can effectively enhance the reliability of the panel being set on the front side of the casing. In this way, when the connecting rod drives the panel to move up and down, the panel can remain stable, and the panel can be prevented from detaching from the connecting rod and falling off, thereby improving the safety of the indoor unit of the air conditioner.

[0019] According to some embodiments of the present invention, there are multiple abutting protrusions, which are spaced apart in the vertical direction of the panel. There are multiple abutting grooves, which abut in a one-to-one correspondence with the multiple abutting protrusions.

[0020] The above technical solution has the following advantages or beneficial effects: on the one hand, it can strengthen the connection between the panel and the connecting rod in the vertical direction of the panel to ensure the stability of the panel during the lifting process, thereby improving the safety of the air conditioner indoor unit when the panel is opened; on the other hand, it can increase the support of the connecting rod for the panel in the vertical direction to prevent the lower end of the panel from shaking and making abnormal noises.

[0021] According to some embodiments of the present invention, the abutting protrusion is provided with a second reinforcing rib.

[0022] The above technical solution has the following advantages or beneficial effects: On the one hand, it can increase the structural strength of the abutting protrusion to ensure the reliability of the abutting fit between the abutting protrusion and the abutting groove, thus ensuring the reliability of the connection between the panel and the connecting rod. On the other hand, it can reduce the material used to make the abutting protrusion, which can not only reduce the weight of the panel and reduce the load on the hook, but also reduce the production cost of the indoor unit of the air conditioner.

[0023] According to some embodiments of the present invention, a second guide slope is provided in the abutment groove, and the second guide slope cooperates with the abutment protrusion.

[0024] The above technical solution has the following advantages or beneficial effects: When installing the panel and connecting rod, the abutting protrusion extends into the abutting groove to abut and cooperate with the abutting groove. During the process of the abutting protrusion extending into the abutting groove, the abutting protrusion can slide into the abutting groove along the second guide slope. This allows the abutting protrusion to quickly extend into the abutting groove, so that the abutting protrusion and the abutting groove can quickly cooperate. This can improve the installation convenience of the panel and connecting rod, thereby improving the production efficiency of the indoor unit of the air conditioner.

[0030] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0031] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0032] The following is based on Figures 1-11 This invention describes an embodiment of an air conditioner indoor unit 100.

[0033] According to an embodiment of the present invention, the indoor unit 100 of the air conditioner includes a housing 10, on which an air inlet 11 and an air outlet 12 are provided. Indoor air enters the indoor unit 100 of the air conditioner through the air inlet 11, and the indoor unit 100 of the air conditioner can blow air of a suitable temperature into the room through the air outlet 12 to adjust the indoor temperature to a preset temperature.

[0034] The indoor unit 100 of the air conditioner according to an embodiment of the present invention further includes a refrigerant circulation loop, an indoor fan, an outdoor fan, a power consumption sensor, and a controller.

[0035] In an embodiment of this utility model, the refrigerant circulation loop of the air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator. The refrigerant circulates between the compressor, condenser, expansion valve, and evaporator, thereby forming a refrigerant circulation loop.

[0036] The compressor compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant. This heat can be exchanged with indoor air to heat the indoor air, or with outdoor air to cool the indoor air. Furthermore, the compressor provides the power for the refrigerant's circulation.

[0037] One of the condensers and evaporator is the outdoor heat exchanger, and the other is the indoor heat exchanger. When the refrigerant enters the outdoor heat exchanger, it exchanges heat with the outdoor air. When the refrigerant enters the indoor heat exchanger, it exchanges heat with the indoor air.

[0038] When the air conditioner is in cooling mode, heat is transferred from the refrigerant to the outdoor air in the outdoor heat exchanger, and heat is transferred from the indoor air to the refrigerant in the indoor heat exchanger. This allows the refrigerant to dissipate indoor heat to the outdoor environment, thereby lowering the indoor temperature.

[0039] When the air conditioner is in heating mode, heat is transferred from the outdoor air to the refrigerant in the outdoor heat exchanger, and heat is transferred from the refrigerant to the indoor air in the indoor heat exchanger. This allows the refrigerant to absorb heat from the outdoor environment and transfer that heat to the indoor environment, thereby raising the indoor temperature.

[0040] An expansion valve can change the pressure of the refrigerant in the refrigerant circulation loop. By throttling and reducing pressure, the expansion valve converts the medium-temperature, high-pressure liquid refrigerant into low-temperature, low-pressure wet vapor, which then absorbs heat in the evaporator to achieve a cooling effect.

[0041] Furthermore, the expansion valve can automatically adjust the flow rate based on the superheat of the gaseous refrigerant at the evaporator outlet, maintaining a stable indoor temperature and meeting the requirements of refrigerant circulation. More importantly, the expansion valve can prevent liquid refrigerant from entering the compressor, avoiding liquid hammer and protecting the compressor from damage.

[0042] The fan assembly is used to drive indoor air through the air inlet 11 into the indoor unit 100 of the air conditioner by rotation, and then through the indoor heat exchanger to exchange heat between the refrigerant and the indoor air. Under the action of the fan assembly, the flow of indoor air to the indoor heat exchanger can be accelerated, thereby accelerating the heat exchange between the indoor air and the refrigerant.

[0043] The outdoor fan is used to drive outdoor air through the outdoor heat exchanger, so that the refrigerant can exchange heat with the outdoor air. Under the action of the outdoor fan, the flow of outdoor air to the outdoor heat exchanger can be accelerated, which can further accelerate the heat exchange between the outdoor air and the refrigerant. Finally, the heat-exchanged air can be blown into the room through the air outlet 12.

[0044] A refrigerant pipe connects the outdoor heat exchanger and the compressor. The refrigerant pipe is used to transfer the refrigerant between the compressor and the outdoor heat exchanger, so as to realize the transfer of heat between the compressor and the outdoor heat exchanger.

[0045] Furthermore, the indoor unit 100 of the air conditioner also includes an electrical control box, which contains a control chip to realize the control function of the indoor unit 100 of the air conditioner.

[0046] Furthermore, the indoor unit 100 of the air conditioner also includes a panel 20, an air outlet 12 located on the front side of the casing 10, and a vertically adjustable connecting rod 13 provided on the front side of the casing 10. Specifically, the casing 10 is the main supporting structure of the indoor unit 100 of the air conditioner. The connecting rod 13 on the front side of the casing 10 can provide a stable and reliable setting position for the connecting rod 13, ensuring the stability of the connecting rod 13 on the casing 10.

[0047] Furthermore, the connecting rod 13 can be raised and lowered. Specifically, in an embodiment of this utility model, the indoor unit 100 of the air conditioner is provided with a drive assembly, which is connected to the connecting rod 13 in a transmission manner to drive the connecting rod 13 to rise and fall.

[0048] Furthermore, the panel 20 is located on the front side of the casing 10, which allows it to be positioned in front of the air outlet 12. This allows the panel 20 to protect other structural components inside the indoor unit 100 of the air conditioner and prevent the heat exchange airflow of the indoor unit 100 from shifting, thereby ensuring stable airflow within the indoor unit 100 to achieve stable heat exchange and air outlet.

[0049] Furthermore, panel 20 is connected to connecting rod 13, which can drive panel 20 to rise. In this way, during the start-up process of indoor unit 100 of air conditioner, in order to increase air intake and realize a new air supply method, the air conditioner can automatically raise panel 20 to expose air outlet 12 and human detection camera at the start, while increasing air intake.

[0050] Furthermore, the connecting rod 13 can also lower the panel 20 to close the air outlet 12 and the human detection camera, so as to prevent dust from entering when the indoor unit 100 of the air conditioner is not in use.

[0051] Furthermore, a hook 21 is provided on the panel 20. Specifically, the panel 20 has a certain structural strength, which can not only provide stable support for the hook 21 on the panel 20, but also ensure the structural reliability of the hook 21 on the panel 20.

[0052] Furthermore, the hook 21 and the panel 20 can move synchronously, so that as the panel 20 moves up and down, the hook 21 also moves up and down synchronously with the panel 20.

[0053] Furthermore, a connecting post 131 is provided on the connecting rod 13. Specifically, the connecting rod 13 has a certain structural strength, which can provide stable and reliable support for the connecting post 131 on the connecting rod 13, so as to ensure the stability and structural reliability of the connecting post 131 on the connecting rod 13.

[0054] Furthermore, the hook 21 is rotatably hooked onto the connecting post 131, which increases the contact area between the hook 21 and the connecting post 131 to ensure the reliability of the connection between the panel 20 and the connecting rod 13.

[0055] Furthermore, the hook 21 is rotatable relative to the connecting post 131, which allows the panel 20 to rotate relative to the connecting rod 13. Thus, when the drive assembly drives the connecting rod 13 to move up and down, the panel 20 can move up and down stably with the connecting rod 13, thereby enabling the panel 20 to move up and down on the front side of the housing 10, and selectively expose the air vent 12 and the human-sensing camera.

[0056] Therefore, this utility model embodiment provides a vertically movable connecting rod 13 on the front side of the housing 10 and a hook 21 on the panel 20, and the hook 21 is rotatably connected to the connecting post 131 on the connecting rod 13. In this way, the panel 20 can be driven to move up and down during the vertical movement of the connecting rod 13. The hook 21 and the connecting post 131 in this utility model have a simple structure and reliable connection. This not only reduces the assembly difficulty of the panel 20 and the housing 10, but also enables the panel 20 to move up and down on the front side of the housing 10.

[0057] Combination Figure 8 As shown, the connecting post 131 is provided with an anti-slip groove 1311. Specifically, the hook 21 on the panel 20 is rotatably hooked to the connecting post 131 on the connecting rod 13, and the main surface of the connecting post 131 is in contact with the surface of the hook 21. When the panel 20 rotates relative to the housing 10, the surface of the hook 21 rubs against the surface of the connecting post 131.

[0058] Furthermore, an anti-slip groove 1311 is provided on the surface of the connecting post 131. On the one hand, the anti-slip groove 1311 has a simple structure and is easy to process, which can simplify the production process of the connecting rod 13. On the other hand, the anti-slip groove 1311 can increase the friction between the hook 21 and the connecting post 131. In this way, when the panel 20 moves up and down with the support, it can ensure that the panel 20 and the connecting rod 13 are stably matched and prevent the panel 20 from slipping. This can improve the stability of the panel 20 when it is raised and lowered, thereby improving the safety of the panel 20 when it is raised and lowered.

[0059] Combination Figure 8 As shown, there are multiple anti-slip grooves 1311. Specifically, multiple anti-slip grooves 1311 are provided on the connecting post 131. This increases the friction between the surface of the connecting post 131 and the surface of the hook 21. When the panel 20 moves up and down with the support, it further ensures the stable fit between the panel 20 and the connecting rod 13, preventing the panel 20 from slipping. This further improves the stability of the panel 20 during lifting and lowering, thereby enhancing the safety of the panel 20 during lifting and lowering.

[0060] Furthermore, multiple anti-slip grooves 1311 are spaced apart on the connecting post 131. This allows the multiple anti-slip grooves 1311 to be independently arranged on the connecting post 131. This not only facilitates the processing and opening of the anti-slip grooves 1311 on the connecting post 131, but also prevents the distance between two adjacent anti-slip grooves 1311 on the connecting post 131 from being too close, which would cause stress concentration on the connecting post 131, thereby ensuring the structural strength and reliability of the connecting post 131.

[0061] Combination Figure 1 and Figure 8 As shown, the connecting post 131 is located at the upper end of the connecting rod 13. Specifically, when the panel 20 rises, the connecting post 131 needs to apply an upward driving force to the panel 20, and the connecting post 131 has an upward supporting force on the hook 21. When the panel 20 falls, the connecting post 131 moves downward, and the hook 21 tends to lose support below, and the panel 20 falls together with the connecting rod 13.

[0062] In an embodiment of this utility model, the panel 20 has a certain area in the vertical direction. The connecting post 131 is set at the upper end of the connecting rod 13 so that the connecting rod 13 and the upper end of the panel 20 are in transmission cooperation. In this way, the lower end of the panel 20 can hang down naturally under the action of gravity, so that the panel 20 always maintains a vertical extension state during the process of rising and falling, so that the panel 20 can protect the air outlet 12.

[0063] Furthermore, by placing the connecting post 131 at the upper end of the connecting rod 13, the upper end of the panel 20 can be connected to the housing 10, and the panel 20 can be rotated forward and upward. If the connecting post 131 is placed at the lower end of the connecting rod 13, the panel 20 cannot be rotated forward and upward, but can only be rotated forward and downward. Although this allows the panel 20 to be opened, it is not convenient for cleaning the filter. Compared to the solution where the connecting post 131 is placed at the lower end of the connecting rod 13, placing the connecting post 131 at the upper end of the connecting rod 13 is more convenient for operation.

[0064] Combination Figure 5 and Figure 10 As shown, the hook 21 is provided with a first reinforcing rib 211. Specifically, the first reinforcing rib 211 can enhance the structural strength of the hook 21, and can ensure that the hook connection between the hook 21 and the connecting post 131 meets the load-bearing requirements of the hook 21 on the panel 20, so as to ensure the reliability of the connection between the panel 20 and the hook 21.

[0065] Combination Figure 10 As shown, the end of the hook 21 is provided with a first guide slope 212, which selectively guides and engages with the connecting post 131.

[0066] Specifically, a first guide slope 212 is provided on the connecting surface of the hook 21 and the connection point. The first guide slope 212 is an inclined surface. The inclined surface is set to cooperate with the surface of the connecting post 131, so that the connecting post 131 can slide into the hook 21 quickly, so that the panel 20 and the connecting rod 13 can be quickly connected. This can improve the installation convenience and efficiency of the panel 20 and the front side of the housing 10.

[0067] Combination Figure 11 As shown, a first abutting part 22 is provided on the panel 20, and a second abutting part 133 is provided on the connecting rod 13. One of the first abutting part 22 and the second abutting part 133 is an abutting groove, and the other is an abutting protrusion. The abutting protrusion and the abutting groove selectively abut and cooperate.

[0068] Specifically, the panel 20 and the connecting rod 13 are further engaged by the first abutting part 22 and the second abutting part 133 to enhance the connection reliability between the panel 20 and the connecting rod 13.

[0069] Furthermore, the abutting engagement of the first abutting part 22 and the second abutting part 133 is actually an abutting engagement of an abutting groove and an abutting protrusion. The structure of the abutting groove and the abutting protrusion is simple, which makes it easy for the first abutting part 22 to be set on the panel 20 and for the second abutting part 133 to be set on the connecting rod 13.

[0070] Furthermore, the abutting groove and the abutting protrusion have a reliable abutting effect. This setting can increase the limit between the panel 20 and the connecting rod 13, and can effectively enhance the reliability of the panel 20 on the front side of the housing 10. In this way, when the connecting rod 13 drives the panel 20 to move up and down, the panel 20 can remain stable, and the panel 20 can be prevented from detaching from the connecting rod 13 and falling off, thereby improving the safety of the indoor unit 100 of the air conditioner.

[0071] Combination Figure 9 and Figure 11 As shown, there are multiple abutment protrusions, which are spaced apart in the vertical direction of the panel 20. There are also multiple abutment grooves, which abut against the multiple abutment protrusions in a one-to-one abutment fit.

[0072] Specifically, multiple abutment protrusions are provided along the vertical direction of the panel 20, and the multiple abutment protrusions are spaced apart from each other. Correspondingly, multiple abutment grooves are also provided on the connecting rod 13, which are spaced apart vertically, to correspond one-to-one with the multiple abutment protrusions. This allows the abutment protrusions and abutment grooves that are in the same position in the vertical direction to cooperate.

[0073] This design strengthens the connection between the panel 20 and the connecting rod 13 in the vertical direction, ensuring the stability of the panel 20 during lifting and lowering, thus improving the safety of the indoor unit 100 when the panel 20 is opened. On the other hand, it increases the support of the connecting rod 13 for the panel 20 in the vertical direction, preventing the lower end of the panel 20 from shaking or making abnormal noises.

[0074] Combination Figure 11 As shown, a second reinforcing rib 221 is provided on the abutting protrusion. Specifically, providing a second reinforcing rib 221 on the abutting protrusion can, on the one hand, increase the structural strength of the abutting protrusion to ensure the reliability of the abutting fit between the abutting protrusion and the abutting groove, thus ensuring the reliability of the connection between the panel 20 and the connecting rod 13. On the other hand, it can reduce the amount of material used to manufacture the abutting protrusion, which not only reduces the weight of the panel 20 and helps to reduce the load on the hook 21, but also helps to reduce the production cost of the indoor unit 100 of the air conditioner.

[0075] Combination Figure 8 As shown, a second guide slope 1331 is provided in the abutment groove, and the second guide slope 1331 guides and cooperates with the abutment protrusion. Specifically, when installing the panel 20 and the connecting rod 13, the abutment protrusion extends into the abutment groove to abut against the groove. During the process of the abutment protrusion extending into the groove, the abutment protrusion can slide into the groove along the second guide slope 1331. This allows the abutment protrusion to quickly extend into the groove, so that the abutment protrusion and the groove can quickly cooperate. This improves the ease of installation of the panel 20 and the connecting rod 13, thereby increasing the production efficiency of the indoor unit 100 of the air conditioner.
