Description

Technical Field

[0001] This utility model relates to the technical field of wall-mounted air conditioner indoor units, and in particular to a wall-mounted air conditioner indoor unit. Background Technology

[0002] As people's living standards improve, air conditioners have become commonplace in households. An air conditioner, also known as an air conditioner, regulates parameters such as temperature, humidity, cleanliness, and airflow within a room (or enclosed space or area) to meet human comfort requirements.

[0003] The air conditioner's display device is the core interface of the human-machine interface (HMI). Its main function is to convey the air conditioner's operating status, settings, and fault information to the user in an intuitive way, allowing the user to easily monitor and control the air conditioner.

[0004] In related technologies, display devices are generally mounted on a panel. When the panel is height-adjustable, if the display components are placed on the panel, the display cables must be routed from the panel to the electrical control box on the base. Because the display cables are relatively thick and stiff, this can easily obstruct the movement of the height-adjustable panel or even cause it to jam. Some display components are also mounted directly on the right side of the air vent, but there is an angle between the user's line of sight and the normal to the display components, which can easily result in unclear display. Furthermore, static displays are not considered high-end and appear rather ordinary. Utility Model Content

[0020] 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.

[0021] The following is for reference. Figures 1-7 Description of a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model.

[0022] Referring to the figure, the wall-mounted air conditioner indoor unit 100 of this embodiment includes a casing, a heat exchanger, a fan, and a display device 10. The casing is installed indoors and forms the overall appearance of the wall-mounted air conditioner indoor unit 100.

[0023] refer to Figure 1 and Figure 2 As shown, the casing is roughly rectangular in shape. The casing has a top and a bottom, which are opposite each other in the height direction (vertical direction). The left and right sides of the casing are opposite each other in the length direction (horizontal direction), and the front and rear sides of the casing are opposite each other in the thickness direction (front-back direction).

[0024] The casing is located at the top of the room or in the upper space of the room, with the front of the casing facing the user and the rear of the casing facing the wall, making it suitable for connection with the wall.

[0025] It should be noted that the directions described in the text are based on the direction the user faces when facing the indoor unit of the air conditioner. Specifically, the side of the indoor unit facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction the user faces when facing the indoor unit.

[0026] refer to Figure 1 and Figure 2 The housing may include an outer cover 21 and a front panel 22. The outer cover 21 has an air inlet 212 and an air outlet 213. The outer cover 21 is generally in the shape of a cuboid frame, and the front side of the outer cover 21 has a frame opening. The front panel 22 is located on the front side of the outer cover 21. The outer cover 21 and the front panel 22 are connected to form the housing.

[0027] The outer casing 21 has a heat exchange air duct inside. The heat exchange air duct is used to house and fix various components in the indoor unit of the air conditioner, which can prevent foreign objects from colliding with the various components inside the outer casing 21, thereby improving the reliability of the indoor unit of the air conditioner during transportation or installation.

[0028] The outer casing 21 has an air inlet 212. The air inlet 212 is connected to the heat exchange duct and serves as an inlet for external air to flow into the casing, allowing indoor air to enter the heat exchange duct through the air inlet 212.

[0029] The outer casing 21 has an air outlet 213. The air outlet 213 is connected to the heat exchange air duct and serves as the outlet for the heat exchange airflow inside the casing, allowing the airflow inside the heat exchange air duct to flow out through the air outlet 213.

[0030] The wall-mounted air conditioner indoor unit 100 also includes a control device. The control device is configured to control the compressor's operating frequency, the expansion valve's opening degree, the outdoor fan's speed, and the indoor fan's speed. The control device is connected to the compressor, expansion valve, outdoor fan, and indoor fan via data cables to transmit communication information.

[0031] The control device includes a processor. The processor may include a central processing unit (CPU), a microprocessor, or an application-specific integrated circuit (ASIC), and may be configured to perform corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device. The non-transitory computer-readable storage medium may include magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes), smart cards, or flash memory devices (e.g., erasable programmable read-only memory (EPROM), card, stick, or keyboard drive).

[0032] In cooling mode, since the compressor and outdoor heat exchanger are connected, the refrigerant in the compressor can exchange heat with the outdoor air through the outdoor heat exchanger and release heat to the outside. At this time, the refrigerant becomes a high-pressure liquid. Next, the high-pressure liquid is throttled through the expansion valve to reduce its pressure and temperature, becoming a low-temperature, low-pressure liquid. Finally, the low-temperature, low-pressure liquid exchanges heat with the indoor air through the indoor heat exchanger, absorbing indoor heat and cooling the indoor air.

[0033] In heating mode, the air conditioning system compresses refrigerant gas into high-temperature, high-pressure gas through the air conditioning compressor. The refrigerant exchanges heat with the indoor air through the indoor heat exchanger, absorbing indoor heat and heating the indoor air. At this time, the refrigerant becomes high-pressure gas. Then, the high-pressure gas is throttled through the expansion valve, reducing its pressure and temperature, becoming low-temperature, low-pressure gas. Finally, the low-temperature, low-pressure gas exchanges heat with the outdoor air through the outdoor condenser, releasing heat to the outside.

[0034] Among them, reference Figure 5 As shown, the air inlet 212 can be located at the top of the outer casing 21. The air outlet 213 can be located at the bottom of the outer casing 21 and near the front side of the outer casing 21, that is, the air outlet 213 is located at the bottom front side of the outer casing 21. In this embodiment, when the wall-mounted air conditioner indoor unit 100 is working, the wall-mounted air conditioner indoor unit 100 takes in air from the top and exits air to the front, which is convenient for installation.

[0035] Reference Figure 5 As shown, the air outlet 213 can be elongated and can extend along the length of the casing, which improves the aesthetics of the wall-mounted air conditioner indoor unit 100.

[0036] In some embodiments of this application, the housing may also include a base that forms the rear side of the wall-mounted air conditioner indoor unit 100 and is adapted to be mounted on a wall.

[0037] The outer cover 21 has an open rear side, covers the front side of the base and is connected to the base, and defines a heat exchange air duct between the outer cover 21 and the base. The outer cover 21, the base and the front panel 22 together form the casing.

[0038] In some embodiments of this application, such as Figure 2 As shown, the wall-mounted air conditioner indoor unit 100 may include an air guide plate 23. The air guide plate 23 is rotatably connected to the casing, and an air outlet 213 is provided on the air guide plate 23. The air guide plate 23 opens or closes the air outlet 213, and when the air guide plate 23 opens the air outlet 213, it is used to guide the heat exchange airflow.

[0039] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include a heat exchanger. The heat exchanger extends along the length of the casing and is disposed within the outer cover 21 for heat exchange with the airflow inside the casing.

[0040] The heat exchanger is located between the air inlet 212 and the air outlet 213 to exchange heat with the air entering from the air inlet 212, and then exhaust it to the room from the air outlet 213.

[0041] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include a fan. The fan is disposed inside the outer casing 21, and the axial direction of the fan extends along the length of the casing. It is used to drive indoor air outside the casing to enter the heat exchange duct inside the casing through the air inlet 212. The fan drives the air in the heat exchange duct to flow along the air inlet 212 toward the air outlet 213.

[0042] The fan is located below the heat exchanger. The heat exchanger can be located inside the air inlet 212. The fan can be located on the side of the heat exchanger away from the air inlet 212. That is, in the airflow direction within the casing, the fan is downstream of the heat exchanger.

[0043] When the wall-mounted air conditioner indoor unit 100 is running, indoor air enters the outer casing 21 from the air inlet 212 under the operation of the fan. The indoor air in the heat exchange duct flows through the heat exchanger for heat exchange. The heat-exchanged airflow is discharged to the outside of the room through the air outlet 213, thereby enabling the wall-mounted air conditioner indoor unit 100 to cool and heat, play a role in regulating the indoor temperature, and achieve the user's comfortable temperature.

[0044] Display device 10 is the core interface of the human-machine interface (HMI). The main function of display device 10 is to convey the air conditioner's operating status, setting parameters, and fault information to the user in an intuitive way, allowing the user to easily monitor and control the air conditioner.

[0045] The most basic function of the display device 10 is to show the operating status and mode, allowing users to know at a glance what the air conditioner is doing. For example, it can display the operating mode, showing whether it is currently cooling, heating, dehumidifying, fan blowing, or automatic mode. This is usually represented by icons such as snowflakes, suns, water droplets, or fans. Another example is the display of fan speed, showing the fan rotation speed, such as automatic, low, medium, high, or silent. Yet another example is the display of the airflow direction, showing whether the air guide vane 23 is oscillating and its oscillation state.

[0046] Furthermore, the display device 10 can also display setting parameters, allowing the user to confirm whether the user's settings have been successfully entered. For example, setting the temperature and timer for on / off. Displaying the set temperature is one of the most important pieces of information, clearly showing the temperature the user wants the room to reach.

[0047] Furthermore, the display device 10 can also display sensor information (environmental monitoring). The wall-mounted air conditioner indoor unit 100 has built-in sensors that feed data back to the display device 10. For example, the display shows the current indoor temperature, allowing users to adjust settings based on the real-time temperature detected by the air conditioner. Another example is the humidity display, showing the current humidity detected by the air conditioner.

[0048] In addition, combined Figures 2-4 As shown, a receiving cavity 211 is provided on the lower side of the outer cover 21, and the receiving cavity 211 and the air outlet 213 are spaced apart. The display device 10 is located in the receiving cavity 211. In other words, by placing the display device 10 on the outer cover 21, the potential danger of the electrical connection cable of the display device 10 jamming the front panel 22 can be avoided.

[0049] The display device 10 is rotatably disposed within the receiving cavity 211 so that it flips open when the indoor unit 100 of the wall-mounted air conditioner is started. In this way, when the display device 10 is flipped open, the angle between the normal and the user's line of sight can be reduced, making the display clearer; and when the air conditioner is turned off, the display device 10 flips closed to avoid an abrupt appearance and to prevent damage from bumps.

[0050] In addition, the flip-opening and closing of the display device 10 can make the wall-mounted air conditioner indoor unit 100 look more high-end and technological, increasing the added value of the air conditioner.

[0051] Therefore, by mounting the display device 10 on the outer casing 21, the potential danger of the electrical connection cable of the display device 10 jamming the front panel 22 can be avoided. When the display device 10 is flipped open, the angle between the normal and the user's line of sight can be reduced, making the display clearer. When the air conditioner is turned off, the display device 10 is flipped closed, avoiding an abrupt appearance and preventing damage from bumps.

[0052] like Figure 3 and Figure 4 As shown, the display device 10 includes a housing 11, a display 12, and a cover 13. The housing 11 has a receiving space, the display 12 is disposed within the receiving space, and the cover 13 covers the housing 11. The display 12 is responsible for displaying parameters, while the housing 11 and cover 13 provide physical protection and structural support. Together, they ensure the stable operation of the air conditioner's display function and the user's interactive experience.

[0053] In addition, such as Figure 3 and Figure 4 As shown, the display device 10 also includes a support shaft 14, which is fixed to the cover plate 13 and whose two ends are fitted onto the outer casing 21. The support shaft 14 is rotatable relative to the outer casing 21. Thus, the support shaft 14 and the cover plate 13 are integrally formed, so that when the support shaft 14 rotates, it can drive the cover plate 13 to rotate together, thereby allowing the display device 10 to rotate with the support shaft 14. This allows the display device 10 to be rotated open when needed and to be rotated closed when not needed.

[0054] The casing 11 is typically made of ABS plastic (high temperature resistant and anti-aging), which prevents dust from entering the circuit gaps of the display 12 and avoids short circuits; at the same time, it blocks indoor moisture (such as during the humid season in southern China) from corroding electronic components and extends the life of the motherboard. The casing 11 is made of non-metallic material, which can isolate the weak current in the circuit of the display 12 and improve safety.

[0055] The inner side of the housing 11 is designed with buckles, screw holes or positioning posts to accurately fix the display 12 and prevent the vibration of the air conditioner during operation from causing the components to shift and thus causing display failure.

[0056] The housing 11 has snap-fit ​​structures at opposite ends that mate with the connecting structure; and / or, the housing 11 has fastening structures that mate with the connecting structure. The housing 11 can be connected to the connecting structure via snap-fit ​​structures or fastening structures, thereby ensuring reliable connection between the housing 11 and the cover plate 13.

[0057] In some embodiments of this application, the snap-fit ​​structure includes insert blocks and elastic snaps formed at opposite ends of the housing 11, and the connection structure includes multiple slots formed on the cover plate 13. Some slots are inserted into the insert blocks, and some slots have snap-fit ​​blocks on their inner sides, with the elastic snaps inserted into the slots and snap-fitting with the snap-fit ​​blocks.

[0058] According to an optional embodiment of this utility model, the main body of the cover plate 13 is made of metal. When a user looks at the casing, since the metal cover plate 13 occupies most of the entire cover plate 13, the user's attention is drawn to the metal cover plate 13, causing them to overlook the small area of ​​the plastic cover plate 13. Therefore, by setting the metal cover plate 13, the texture of the cover plate 13 is enhanced, thereby highlighting the high-end nature of the wall-mounted air conditioner indoor unit 100.

[0059] According to another optional embodiment of the present invention, the main body of the cover plate 13 is made of plastic cover plate 13. Without affecting the overall texture of the cover plate 13, the plastic cover plate 13 can be injection molded, which facilitates the plastic cover plate 13 to be set with an integrally formed connection structure, a snap-fit ​​structure and other related structures, so as to be fixedly connected with the housing 11, the driving component 31 and the like.

[0060] Meanwhile, the plastic cover plate 13 can achieve light transmission display directly or through a process. By installing the display 12 on the back side of the plastic cover plate 13, the display reception effect is guaranteed.

[0061] Among them, such as Figures 3-4 As shown, the display device 10 also includes a driving component 31 and a transmission component 32. The driving component 31 is fixed to the outer casing 21, and the transmission component 32 is fixed to the output end of the driving component 31. The transmission component 32 and the support shaft 14 are in a transmission cooperation. That is, through the mutual transmission between the driving component 31 and the transmission component 32, and the mutual transmission between the transmission component 32 and the support shaft 14, when the driving component 31 is started, it can drive the transmission component 32, and then the transmission component 32 can drive the support shaft 14, thereby realizing the unfolding and resetting of the display device 10 through the driving component 31.

[0062] Among them, the driving component 31 can be a stepper motor, which can convert digital electrical pulse signals into precise angular displacement (rotation) or linear displacement (linear motion).

[0063] In addition, the wall-mounted air conditioner indoor unit 100 also includes: an air guide plate 23 and an air guide plate motor. Specifically, the air guide plate 23 is divided into a vertical air guide plate and a horizontal air guide plate. The vertical air guide plate is located outside the air outlet 213, and is usually larger and wider. It controls the vertical airflow angle. The horizontal air guide plate is located inside the air outlet 213, behind the vertical air guide plate. It is usually composed of multiple narrower blades and controls the horizontal airflow angle.

[0064] The air deflector 23 prevents direct airflow, improving comfort, especially during cooling. Direct cold air blowing directly on the body can cause discomfort and even "air conditioning sickness." By adjusting the air deflector 23, the airflow can be directed towards the ceiling or walls, allowing the cool air to sink naturally, creating a gentle, even circulation and completely avoiding direct airflow. The air deflector 23 also optimizes airflow distribution and quickly regulates room temperature. During cooling, adjusting the vertical air deflector to horizontal or slightly upward utilizes the sinking property of cool air to evenly lower the room temperature. During heating, adjusting the vertical air deflector downward allows the hot air to rise naturally after being blown from the bottom, warming the entire room more quickly.

[0065] Thus, the transmission component 32 can be connected between the support shaft 14 and the air guide plate motor, that is, the air guide plate motor can be used to replace the drive component 31, thereby saving the drive component 31 and reducing costs.

[0066] In addition, refer to Figure 4 As shown, a transmission part 143 is provided on the support shaft 14, and the transmission part 143 and the transmission component 32 are in a transmission cooperation. In this way, the mutual transmission between the driving component 31 and the transmission component 32, as well as the mutual transmission between the transmission component 32 and the transmission part 143, can drive the transmission component 32 when the driving component 31 is started, and then the transmission component 32 drives the transmission part 143, thereby realizing the unfolding and resetting of the display device 10 through the driving component 31.

[0067] Specifically, a transmission gear is provided at one end of the support shaft 14. It is an incomplete gear. The transmission component 32 is a drive gear, and the drive component 31 is a stepper motor. The stepper motor drives the drive gear and then drives the transmission gear to drive the cover plate 13 to rotate along with the display 12 and the housing 11.

[0068] like Figures 4-5As shown, the support shaft 14 includes a first shaft 141 and two second shafts 142. The first shaft 141 is fixedly connected to the display cover, and the two second shafts 142 are respectively disposed at both ends of the first shaft 141. The two second shafts 142 are fitted onto the outer cover 21. In other words, the support shaft 14 is composed of the first shaft 141 in the middle and the second shafts 142 at both ends, which allows the second shafts 142 at both ends to be rotatably fitted onto the outer cover 21, thereby enabling the display device 10 to be flipped as a whole.

[0069] Furthermore, referring to Figure 5 As shown, the diameter of the first shaft 141 is larger than the diameter of the second shaft 142. By setting the second shafts 142 at both ends to be smaller than the first shaft 141 in the middle, it is convenient to pivot the shaft, that is, the second shafts 142 are hidden inside the outer cover 21.

[0070] like Figure 7 As shown, the receiving cavity 211 is provided with a through hole and a mating groove 214, which are connected. The second shaft 142 is fitted into the through hole, and a portion of the first shaft 141 is fitted into the mating groove 214, which is an arc-shaped groove. This arrangement, with the second shaft 142 fitting into the through hole and a portion of the first shaft 141 fitting into the mating groove 214, reduces noise during rotation of the support shaft 14 and also reduces friction during rotation of the first shaft 141.

[0071] In addition, refer to Figure 5 As shown, a first mating step is provided at the opening of the receiving cavity 211, and a second mating step 131 is provided at the edge of the cover plate 13. The first and second mating steps 131 engage with each other. The engagement of the first and second mating steps 131 ensures a tight fit between the cover plate 13 and the receiving cavity 211, thus improving the sealing performance of the receiving cavity 211. Furthermore, the engagement of the first and second mating steps 131 also serves as a limiting mechanism, preventing the drive component 31 from continuing to operate once the first and second mating steps 131 are engaged.

[0072] The display device 10 is configured such that, when opened, the cover plate 13 and the front panel 22 are parallel, or the angle between the cover plate 13 and the front panel 22 is an acute angle. That is, the display device 10 has multiple opening angles, which allows the display device 10 to stop at different positions, thereby making it convenient for users to see the display content of the display device 10 from different positions.

[0073] For example, the display device 10 can be parallel to the front panel 22 when opened, or the angle between the display device 10 and the front panel 22 can be 45 degrees, or the angle between the display device 10 and the front panel 22 can be 30 degrees. Of course, the angle of the display device 10 when opened is not limited to the above angles, and can also be other acute angles.

[0074] The wall-mounted air conditioner indoor unit 100 according to a second aspect embodiment of the present invention includes: a casing, a heat exchanger, a fan, and a display device 10. The casing is installed indoors and forms the overall appearance of the wall-mounted air conditioner indoor unit 100.

[0075] refer to Figure 1 and Figure 2 As shown, the casing is roughly rectangular in shape. The casing has a top and a bottom, which are opposite each other in the height direction (vertical direction). The left and right sides of the casing are opposite each other in the length direction (horizontal direction), and the front and rear sides of the casing are opposite each other in the thickness direction (front-back direction).

[0076] The casing is located at the top of the room or in the upper space of the room, with the front of the casing facing the user and the rear of the casing facing the wall, making it suitable for connection with the wall.

[0077] It should be noted that the directions described in the text are based on the direction the user faces when facing the indoor unit of the air conditioner. Specifically, the side of the indoor unit facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction the user faces when facing the indoor unit.

[0078] refer to Figure 1 and Figure 2 The housing may include an outer cover 21 and a front panel 22. The outer cover 21 has an air inlet 212 and an air outlet 213. The outer cover 21 is generally in the shape of a cuboid frame, and the front side of the outer cover 21 has a frame opening. The front panel 22 is located on the front side of the outer cover 21. The outer cover 21 and the front panel 22 are connected to form the housing.

[0079] The air inlet 212 can be located at the top of the outer casing 21. The air outlet 213 can be located at the bottom of the outer casing 21 and near the front side of the outer casing 21, that is, the air outlet 213 is located at the bottom front side of the outer casing 21. In this embodiment, when the wall-mounted air conditioner indoor unit 100 is working, the wall-mounted air conditioner indoor unit 100 takes in air from the top and exits air to the front, which is convenient for installation.

[0080] The air outlet 213 can be elongated and can extend along the length of the casing, which improves the aesthetics of the wall-mounted air conditioner indoor unit 100.

[0081] Display device 10 is the core interface of the human-machine interface (HMI). The main function of display device 10 is to convey the air conditioner's operating status, setting parameters, and fault information to the user in an intuitive way, allowing the user to easily monitor and control the air conditioner.

[0082] In addition, a receiving cavity 211 is provided on the lower side of the outer cover 21, and the receiving cavity 211 and the air outlet 213 are spaced apart. The display device 10 is located in the receiving cavity 211. That is to say, by placing the display device 10 on the outer cover 21, the potential danger of the electrical connection cable of the display device 10 jamming the front panel 22 can be avoided.

[0083] The display device 10 includes a display body and a support shaft 14. The display body is disposed in the receiving cavity 211, and the support shaft 14 is fixed on the display body and the two ends of the support shaft 14 are fitted on the outer cover 21. The support shaft 14 can rotate relative to the outer cover 21.

[0084] The display unit is rotatably mounted within the receiving cavity 211 under the drive of the support shaft 14, so that it flips open when the wall-mounted air conditioner indoor unit 100 is started. In this way, when the display unit flips open, the angle between the normal and the user's line of sight can be reduced, making the display clearer; and when the air conditioner is turned off, the display unit flips closed, avoiding an abrupt appearance and preventing damage from bumps.

[0085] In addition, the flip-opening and closing of the main display can make the wall-mounted air conditioner indoor unit 100 look more high-end and technological, increasing the added value of the air conditioner.
