[0039] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0040] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0041] In addition, if the embodiments of the utility model involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one feature. In addition, "and / or" or "and / or" appearing throughout the text means that the three parallel schemes are included, taking "A and / or B" as an example, including A scheme, or B scheme, or A and B simultaneously meet the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skill in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0042] With the increasing public concern about air quality, traditional air conditioners need to have the ability to improve indoor air quality in addition to basic cooling and heating functions. To this end, air conditioners with air quality improvement capabilities have emerged, which are referred to as "air machines" for short. Such air machines optimize air quality by regulating temperature, humidity, and wind speed, as well as providing air purification and fresh air supply. However, most air machines on the market are equipped with only basic digital display devices, such as traditional double-eight display boards, whose functions are limited to simple digital display. To further enhance user experience and provide more intuitive visual feedback, existing technical solutions add a larger display area to the original double-eight display board. However, this approach results in unnecessary spacing between the double-eight display board and the newly added display area, leading to low space utilization efficiency. Moreover, since the two display parts require independent control boards for support and operation, this not only increases the cost of the air machine but also makes it larger.

[0043] Therefore, the utility model provides a display device 100, which aims to meet the diversified needs of users while reducing the cost and size of the air machine.

[0044] Please refer to Figure 1 In an embodiment of the utility model, the display device 100 includes:

[0045] The control board 1 is provided with at least two mounting areas 11.

[0046] At least two display devices 2, each of which is arranged in a mounting area 11.

[0047] In this embodiment, the control board 1 is the basic device of the entire display device 100, responsible for providing physical support and electrical connection for all display devices 2 mounted on it. The control board 1 is provided with at least two mounting areas 11, which can be physically independent but closely connected, or different partitions on the same panel, ensuring that there is no unnecessary spacing between the display devices 2, thereby maximizing the use of space. By providing multiple mounting areas 11 on one control board 1, this design can effectively integrate different types of display requirements, for example, one mounting area 11 can be used for basic digital information display, and another mounting area 11 can be used to display more complex graphics or text information. In addition, the single control board 1 design can also simplify the circuit connection and control system, reducing manufacturing complexity.

[0048] Each installation area 11 can be equipped with different types of display devices 2 according to functional requirements, where the types of display devices 2 can include but are not limited to basic digital display devices, advanced graphical / text display devices. The basic digital display device can be a traditional double-eight display panel, mainly used to display the digital information of the substrate, such as the indoor temperature, humidity and other key parameters. The advanced graphical / text display device can be an LCD panel, an LED display screen or other types of displays, suitable for presenting more complex information, such as air quality index, operation interface, warning information, etc. By adopting at least two different display devices 2, the diversity of display functions and the richness of information display can be significantly improved without increasing the size of the device. This not only enhances the user's visual experience, but also enables the device to respond more flexibly to different levels of information display needs.

[0049] The technical scheme of the utility model discloses at least two installation areas 11 are arranged on the control panel 1, and one type of display device 2 is arranged in each installation area 11, so that different display functions can be integrated on the same control panel 1, the problem of space waste caused by the physical distance between different display areas in the traditional air machine is solved, and the space utilization is improved. Moreover, since all the display devices 2 are supported and controlled by the single control panel 1, the number of control panels 1 required can be reduced, the production cost can be reduced, and the overall volume of the air machine can be reduced. In this way, the multi-dimensional running state of the air machine can be intuitively displayed, the compactness and economy of the device can be ensured, and the user experience can be improved.

[0050] Please refer to Figure 2 In an embodiment of the utility model, the display device 100 further comprises:

[0051] The shell 3 is provided with the control panel 1 and at least two display devices 2.

[0052] In this embodiment, the shell 3 serves as the external protection structure of the display device 100, and can provide physical protection for the control panel 1 and the display devices 2 to prevent damage to the circuit caused by external factors such as dust and moisture. The control panel 1 and the at least two display devices 2 are arranged in the shell 3, which means that all the core electronic components of the display device 100 are compactly arranged in a shell 3, thereby realizing the high integration of the display device 100. For example, the control panel 1 can be fixed at the bottom or back of the shell 3 to facilitate connection with the display devices 2; and different display devices 2 can be reasonably distributed in front of or on top of the shell 3 according to the needs of human-computer interaction, to ensure that the information is clear and visible and easy to operate.

[0053] In particular, the display device 2 can include LED driving chips and lamp beads and the like. In order to ensure that light can smoothly penetrate the shell 3 to achieve a clear visual effect, the material of the shell 3 corresponding to the position of the lamp bead needs to use a light-transmitting material. The light-transmitting material can include but is not limited to acrylic (PMMA) and polycarbonate (PC). For example, acrylic is a common transparent plastic material with good light transmission, weather resistance and processing performance. It not only has relatively low cost, but also can be customized into various shapes and colors according to design requirements, and is very suitable for making the shell 3 part with a display window.

[0054] Referring to Figures 2 to 4 In an embodiment of the present application, a part of the shell 3 is provided with a first accommodating cavity 301, and another part of the shell 3 cooperates with the control panel 1 to form a second accommodating cavity 302.

[0055] At least one of the display devices 2 is accommodated in the first accommodating cavity 301, and another of the display devices 2 is accommodated in the second accommodating cavity 302.

[0056] In this embodiment, a part of the shell 3 is provided with a first accommodating cavity 301, and the first accommodating cavity 301 has a larger space, mainly used for accommodating at least one of the display devices 2 which has a larger size or needs more protection, which can be defined as a first display device 21, such as a traditional double-eight display panel, used for displaying digital information of a substrate. The first accommodating cavity 301 can provide basic physical protection and fixed position for the first display device 21. Another part of the shell 3 cooperates with the control panel 1 to form a second accommodating cavity 302, and the second accommodating cavity 302 has a relatively small space, which is located inside the first accommodating cavity 301, used for accommodating at least one of the display devices 2 which has a smaller size or needs less protection, which can be defined as a second display device 22, such as a larger LCD panel or LED display screen, which can display more complex information content, such as air quality index, temperature and humidity and other environmental parameters. By arranging different display devices 2 in respective accommodating cavities, it is helpful to reduce the electromagnetic interference that may be generated between them, and ensure the stability and accuracy of signal transmission.

[0057] Referring to Figure 2 In an embodiment of the present application, the shell 3 is provided with a diffusion film corresponding to the cavity wall of the second accommodating cavity 302.

[0058] In the embodiment, the diffusion film is a kind of thin film material with special optical properties, and its surface is usually treated to form a microstructure, which can effectively scatter light and make the light distribution more uniform. The diffusion film is placed on the cavity wall of the second accommodating cavity 302, that is, close to the second display device 22. The purpose of this is to ensure that the light emitted from the second display device 22 can be more evenly distributed throughout the display area, thereby improving the clarity and contrast of the image, making the displayed content easier to read and understand. Especially for high-brightness display devices 2, such as some types of LED display screens, the diffusion film can effectively prevent too strong light from directly entering the human eye, causing discomfort. That is, by using the diffusion film, a more comfortable and natural visual experience can be created. Whether it is during the day or at night, users can enjoy consistent and high-quality display effects, reducing visual fatigue caused by changes in ambient light. It is also because of the use of the diffusion film that the display of the second display device 22 can be more uniform, so the second display device 22 can use fewer lamp beads to achieve the required display effect, and the reduction in the number of lamp beads can further reduce the size of the display device 100.

[0059] Please refer to Figure 2 In an embodiment of the utility model, the shell 3 includes:

[0060] The base 31, the control panel 1 is arranged on the base 31;

[0061] The cover 32, a part of the cover 32 is covered on the base 31, and the base 31 is enclosed to form the first accommodating cavity 301, and the other part of the cover 32 is covered on the control panel 1, and the control panel 1 is enclosed to form the second accommodating cavity 302.

[0062] In the embodiment, the base 31 is a base part of the shell 3, used to fix and support the core components of the whole display device 100, such as the control board 1, etc. A part of the cover plate covers on the base 31, and together with the base 31 forms a first accommodating cavity 301. The first accommodating cavity 301 is mainly used to accommodate the first display device 21, such as a traditional double-eight display board. The first display device 21 can be placed in a relatively independent space. Another part of the cover body 32 covers on the control board 1, and together with the control board 1 forms a second accommodating cavity 302. The second accommodating cavity 302 is used to place the second display device 22, such as an LCD panel or an LED display screen, to provide additional protection and isolation for these more complex and precise display devices. By forming the first accommodating cavity 301 and the second accommodating cavity 302 by different parts of the base 31 and the cover body 32 respectively, the two different display devices 2 are separated in the respective accommodating cavities, which on the one hand helps to reduce the electromagnetic interference between them, ensures the stability and accuracy of signal transmission, and on the other hand can provide physical protection for the corresponding display devices 2, thereby reducing the influence of external factors such as dust and moisture on the display devices 2, and improving the reliability and durability of the display device 100. And the reasonable planning of the first accommodating cavity 301 and the second accommodating cavity 302 can also make the internal space be used efficiently, which not only ensures that each display device 2 has enough installation space, but also avoids unnecessary increase in volume, and maintains the compactness of the whole product.

[0063] Please refer to Figure 2 In an embodiment of the utility model, the cover body 32 includes:

[0064] The first cover plate 321 forms the first accommodating cavity 301 together with the base 31;

[0065] The second cover plate 322 forms the second accommodating cavity 302 together with the control board 1, and the first cover plate 321 is provided with a mounting opening 303 for the second cover plate 322 to pass through.

[0066] In the embodiment, the first cover plate 321 cooperates with the base 31 to form a first accommodating cavity 301 for accommodating the first display device 21. The second cover plate 322 cooperates with the control board 1 to form a second accommodating cavity 302 for accommodating the second display device 22. The first cover plate 321 is provided with a mounting opening 303 for the second cover plate 322 to pass through. The mounting opening 303 allows the second cover plate 322 to pass through the first cover plate 321, thereby forming an independent second accommodating cavity 302 inside the first accommodating cavity 301. Through cooperation with the mounting opening 303 on the first cover plate 321, the second cover plate 322 can be accurately positioned and fixed at the required position, ensuring that the space of the second accommodating cavity 302 is effectively utilized, and providing necessary protection and support for the second display device 22, while ensuring that the first display device 21 and the second display device 22 are sufficiently isolated from each other, reducing the possibility of mutual interference. In addition, the first cover plate 321 and the second cover plate 322 are separately arranged, and different materials can be used to manufacture the two cover plates according to actual needs.

[0067] Referring to Figure 3 and Figure 4 In an embodiment of the utility model, the display device 100 further comprises:

[0068] The main controller 4 is arranged on the control board 1 and is electrically connected with the at least two display devices 2, and the main controller 4 is used for controlling the at least two display devices 2 to work.

[0069] In the embodiment, the main controller 4 serves as a central processing unit and is arranged on the control board 1, and is responsible for receiving instructions from the air machine or the user and regulating the working state of the at least two types of display devices 2 (for example, a traditional double-eight display board and an LCD display screen) according to the instructions. The main controller 4 is connected with each type of display device 2 through a circuit, so as to ensure that it can send commands, data and receive feedback information. Since all display operations are uniformly commanded by the main controller 4, the conflict or delay problem caused by multi-head control can be avoided, and the response speed and operation stability of the display device 100 are improved. Because of the presence of the main controller 4, the management of the multiple display devices 2 can be more centralized, the design complexity of the control system is simplified, the control logic does not need to be configured for each display device 2, and the consumption of hardware resources is reduced.

[0070] Referring to Figure 3 and Figure 4 In an embodiment of the utility model, the control board 1 has a first side surface 12 and a second side surface 13 arranged oppositely, the at least two display devices 2 are arranged on the first side surface 12, and the main controller 4 is arranged on the second side surface 13.

[0071] In the embodiment, the first side surface 12 is the side of the control board 1 facing the user, and at least two types of display devices 2 are arranged on this side, so that the display information can be clearly presented to the user through the light-transmitting part of the shell 3. The second side surface 13 is the side of the control board 1 away from the user, and the main controller 4 is arranged on this side. By placing the main controller 4 on the second side surface 13, since the main controller 4 contains integrated circuits running at high speed, strong electromagnetic interference can be generated. Separating the main controller 4 from the display devices 2 can significantly reduce such interference, ensure the quality and stability of signal transmission, and thus improve the reliability of the overall system. By arranging the display devices 2 and the main controller 4 on the two sides of the control board 1 respectively, a more reasonable and compact spatial layout can be achieved. This not only helps to reduce the size of the entire display device 100, but also ensures that each component has sufficient installation space, avoiding physical damage or performance degradation caused by overcrowding.

[0072] Referring to Figure 3 and Figure 4 In an embodiment of the present application, the first side surface 12 is provided with a light reflection layer corresponding to the positions of the at least two types of display devices 2.

[0073] In the embodiment, the first side surface 12 of the control board 1, i.e. the side on which the at least two types of display devices 2 are mounted, is provided with a light reflection layer corresponding to the positions of the display devices 2. The specific implementation is to apply a layer of white oil. This layer of white oil is usually composed of white ink or paint with high reflectivity, and its main function is to redirect the light that would otherwise be absorbed or scattered to the display area, thereby increasing the utilization of light and increasing the display brightness of the display device 100 without adding additional complexity.

[0074] Referring to Figure 3 and Figure 4 In an embodiment of the present application, the control board 1 is made using a double-sided paste component tin paste process. On this basis, the display device 100 can further include a buzzer, a light detection piece 6, and a voice module 5. The voice module 5 includes a voice chip, and the display device 2 includes a lamp bead and a driving chip. Some small components such as the lamp bead, the buzzer, and the light detection piece 6 can be arranged on the first side surface 12, while some large components such as the main controller 4, the voice chip, and the driving chip can be arranged on the second side surface 13. On the one hand, this can avoid the second cover plate 322 from touching the easily damaged main controller 4, voice chip, and driving chip when the second cover plate 322 is installed on the control board 1. On the other hand, it is possible to make room for the light reflection layer to increase the reflection area of light and improve the display effect.

[0075] Referring to Figures 3 to 5 In an embodiment of the present application, the display device 100 further includes:

[0076] The voice module 5 includes an offline voice chip 51 and a microphone 52, the offline voice chip 51 is electrically connected with the microphone 52 and the main controller 4, and the offline voice chip 51 is used to output the voice signal output by the microphone 52 to the main controller 4 when receiving the voice signal.

[0077] In the embodiment, the offline voice chip 51 is an integrated circuit for processing voice signals, which can recognize and analyze voice commands locally (i.e. without relying on the network). The offline voice chip 51 is usually pre-installed with specific voice recognition algorithms and command sets, and can understand and respond to a series of predefined voice instructions. The microphone 52 is used to convert the captured sound waves into voice signals, and then transmit these signals to the offline voice chip 51 for processing. The offline voice chip 51 is directly connected with the microphone 52 to receive the voice signal from the microphone 52. The offline voice chip 51 is also electrically connected with the main controller 4, and after receiving the voice signal and completing the preliminary processing, the processed information is sent to the main controller 4 for executing corresponding operations or feedback. By integrating the voice module 5, the display device 100 can obtain the ability of voice interaction, so that the user can operate the device or obtain information through simple voice commands, improving the convenience and interactivity of use. Since the offline voice chip 51 is used, even in the case where the network is unavailable, the user can still use the voice function, ensuring the availability of the device in any environment.

[0078] The voice module 5 can also include a loudspeaker 53. When the display device 100 is powered on, all the display devices 2 will be lit for 1 second and then turned off. Then, the main controller 4 will broadcast a prompt sound to the user through the loudspeaker 53, indicating that the device has been successfully started and enters the standby state. In the standby state, the voice module 5 enters a low-power mode and continuously detects whether there is a user's voice input. Once the voice input is detected, the main controller 4 will acquire the voice signal through the microphone 52, analyze it and match it with the preset offline voice instruction package. If the matching is successful, the main controller 4 will execute the corresponding control instruction and issue a prompt sound through the loudspeaker 53 to confirm the operation. At the same time, the main controller 4 will also send the control instruction to the control panel 1 through the communication interface to trigger the display devices 2 to perform the light-off control according to the instruction requirement, realizing the visual feedback.

[0079] That is, the main controller 4 can realize offline voice control through the offline voice chip 51, the microphone 52 and the loudspeaker 53, without the need to connect the cloud server through the wireless communication module 8 to realize the decoding of the voice, greatly improving the response speed of the offline voice and further improving the experience of human-computer interaction.

[0080] In another embodiment of the present application, the offline voice chip 51 is arranged on the control panel 1; the display device 100 further comprises a shell 3, and the microphone 52 is arranged on the shell 3.

[0081] In the present embodiment, the offline voice chip 51 is installed on the control panel 1 and integrated with the main controller 4 and other electronic components. In this way, it can be ensured that the voice signal received from the microphone 52 can be efficiently transmitted to the voice processing unit for processing. In order to reduce the influence of electronic elements on the control panel 1 on the pickup effect of the microphone 52, the microphone 52 is arranged on the shell 3 and located at the periphery of the control panel 1. This means that the microphone 52 is not directly mounted on the control panel 1, but is connected to the control panel 1 through wires or other appropriate electrical connection methods. The microphone 52 can be placed at the best pickup position of the shell 3, such as the front, top or side, etc., to ensure the best sound capture effect. These positions are far away from the electronic noise sources on the control panel 1, thereby avoiding the influence of electromagnetic interference and other electrical noise on the received voice signal.

[0082] In another embodiment of the present application, the loudspeaker 53 is arranged on the shell 3.

[0083] In the present embodiment, the loudspeaker 53 is arranged on the shell 3 and located at the periphery of the control panel 1. This means that the loudspeaker 53 is not directly mounted on the control panel 1, but is connected to the control panel 1 through wires or other appropriate electrical connection methods. According to the functional requirements and acoustic design principles of the device, the loudspeaker 53 can be placed at the best sound emitting position of the shell 3, such as the front, top or side, etc., to ensure the best sound propagation effect. These positions are far away from the electronic noise sources on the control panel 1, thereby avoiding the influence of electromagnetic interference and other electrical noise on the sound output.

[0084] Please refer to Figure 5 In an embodiment of the present application, the display device 100 further comprises a light detection member 6, the light detection member 6 is electrically connected with the main controller 4, the light detection member 6 is used for detecting the light intensity of the environment where the display device 100 is located, and the main controller 4 is used for adjusting the display brightness of the display device 2 according to the light intensity detected by the light detection member 6.

[0085] In the embodiment, the light detection piece 6 (such as a photoelectric sensor) is usually mounted on the shell 3 of the display device 100, so as to accurately detect the light intensity of the environment where the device is located. The light detection piece 6 is connected with the main controller 4 through a wire or other appropriate electrical connection mode. The main controller 4 can dynamically adjust the brightness of the display device 2 according to the light intensity data provided by the light detection piece 6. For example, the brightness is increased in bright sunlight to ensure that the information is clearly visible; and the brightness is reduced in a dim environment to reduce eye fatigue and save energy. Such adaptive brightness adjustment function not only improves visual comfort, but also prolongs the service life of the display device 2 and helps to save energy.

[0086] Please refer to Figure 5 In an embodiment of the utility model, the display device 100 further includes a remote control module 7, the remote control module 7 is electrically connected with the main controller 4, is used for receiving external control signal and controls the display device 2.

[0087] In the embodiment, the remote control module 7 can be integrated on the control panel 1, or can be installed as a separate component in the shell 3.
