[0015] The above technical solution has the following advantages or beneficial effects: The voice component can realize voice interaction function. The voice component is connected to the side of the cover body adjacent to the outer cover, which can bring the voice component closer to the user's voice position, reduce the attenuation and interference of sound propagation inside, and improve the sensitivity and accuracy of voice recognition. At the same time, it can be kept away from the fan and air duct, which can reduce the impact of airflow noise on sound pickup.

Detailed Implementation

[0027] 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.

[0028] The following is for reference. Figures 1-10 This invention describes an indoor unit according to an embodiment of the present invention.

[0029] Indoor unit 1 is part of the structure of the air conditioner. The specific structure of the air conditioner will be described in detail below.

[0030] The air conditioner includes an indoor unit 1 and an outdoor unit, which are connected by pipes to transfer refrigerant. The indoor unit 1 includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, outdoor heat exchanger, expansion valve, and indoor heat exchanger, connected in sequence, form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor and indoor heat exchangers to achieve either the air conditioner's cooling or heating mode.

[0031] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0032] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0033] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to increase the contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0034] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet and expel the outdoor air, after it has been heated by the outdoor heat exchanger, through the outdoor air outlet. The outdoor fan provides power for the flow of outdoor air.

[0035] An expansion valve connects the outdoor and indoor heat exchangers. The opening degree of the expansion valve regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between the outdoor and indoor heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve, and its opening degree is adjustable to control the refrigerant flow rate and pressure.

[0036] A four-way valve is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner can perform cooling mode or heating mode.

[0037] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the indoor heat exchanger operates as an evaporator, causing the refrigerant, after dissipating heat from the outdoor heat exchanger, to absorb heat from the indoor air and evaporate. In the heating mode of the air conditioner, the indoor heat exchanger operates as a condenser, causing the refrigerant, after absorbing heat from the outdoor heat exchanger, to dissipate heat to the indoor air and condense.

[0038] In some embodiments, the indoor heat exchanger further includes heat exchange fins to increase the contact area between indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving the heat exchange efficiency between indoor air and the refrigerant.

[0039] The indoor fan is configured to draw indoor air into the indoor unit 1 through the third air inlet and to discharge the indoor air, after heat exchange with the indoor heat exchanger, through the fourth air outlet of the indoor unit 1. The indoor fan provides power for the airflow.

[0040] The air conditioner also includes a control unit, which is mainly used 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 unit is connected to the compressor, expansion valve, outdoor fan, and indoor fan via data cables to transmit communication information.

[0041] The control device includes a processor, which 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).

[0042] like Figures 1-3 As shown, the indoor unit 1 according to an embodiment of the present invention may include: a casing, the casing including: an outer cover 10, and an indoor heat exchanger disposed within the casing. The casing provides protection for the internal components. The outer cover 10 provides protection by covering and protecting the internal components. The indoor heat exchanger exchanges heat between indoor air and refrigerant or other heat exchange media, thereby regulating the indoor temperature. Since the indoor heat exchanger is disposed within the casing, the casing provides protection for it.

[0043] Indoor unit 1 may include an electrical control box, which is housed within the unit casing. The indoor heat exchanger is electrically connected to the electrical control box. The electrical control box can receive signals, process information, execute control logic, and drive actuators. The casing protects the electrical control box. The electrical connection between the indoor heat exchanger and the electrical control box allows the control box to monitor the status of the indoor heat exchanger and control its related actuators, thereby ensuring the safe and efficient operation of indoor unit 1.

[0044] like Figures 1-3 As shown, the indoor unit 1 may include a voice component 20, which is disposed on the outer casing 10 and electrically connected to the electrical control box. The voice component 20 enables voice control and status feedback. The fact that the voice component 20 is disposed on the outer casing 10 avoids the need for drilling holes to install it onto the panel. The electrical connection between the voice component 20 and the electrical control box is the core component for realizing the voice function. Through this electrical connection, the voice component 20 can transmit voice signals to the electrical control box, which can then parse the commands, execute the operations, and provide feedback, thereby enabling the voice function of the indoor unit 1.

[0045] like Figures 4-8 , Figure 10As shown, the voice component 20 includes: a housing 200 located inside the casing, and a cover 201, which includes: a cover body 202, a first latching part 203 connected to the side of the cover body 202 adjacent to the outer cover 10, and a second latching part 204 connected to the side of the cover body 202 adjacent to the outer cover 10. It should be noted that the housing 200 is the main structure of the voice component 20, which can support and fix the internal components. The housing 200 is located inside the casing, at which point the casing can protect the housing 200. The cover 201 can provide protection and isolation. The cover body 202 is the main part of the cover 201, which can also provide protection and isolation. The first snap-fit ​​part 203 can provide a snap-fit ​​function, allowing it to engage with other components. The first snap-fit ​​part 203 can be connected to the cover body 202, and it is connected to the side closest to the outer cover 10. At this time, the first snap-fit ​​part 203 and the cover body 202 form a whole, which facilitates the installation and setting of the cover 201. The second snap-fit ​​part 204 can play a snap-fit ​​function and can be snap-fitted and cooperated with other components. The second snap-fit ​​part 204 can be connected to the cover body 202, and the second snap-fit ​​part 204 is connected to the side close to the outer cover 10. At this time, the second snap-fit ​​part 204 and the cover body 202 form a whole, which facilitates the installation and setting of the cover 201. The voice component 20 can be set on the outer cover 10 through the first snap-fit ​​part 203 and the second snap-fit ​​part 204.

[0046] like Figures 1-3As shown, the outer cover 10 has mounting holes, and the cover body 202 is disposed in the mounting holes. The first snap-fit ​​part 203 and the second snap-fit ​​part 204 both extend into the housing through the mounting holes. The first snap-fit ​​part 203 is pre-attached to the inner side of the outer cover 10, and the second snap-fit ​​part 204 engages with the box body 200 so that the box body 200 abuts against the inner side of the outer cover 10. The mounting holes serve a mounting function, allowing other components to be installed on the outer cover 10. Through the mounting holes, the cover body 202 can be disposed on the outer cover 10. The first snap-fit ​​part 203 and the second snap-fit ​​part 204 can extend into the housing through the mounting holes. The first snap-fit ​​part 203 is pre-attached to the inner side of the outer cover 10, at which point the first snap-fit ​​part can pre-fix the cover body 202, thus pre-fixing the cover body 202 to the outer cover 10. The second snap-fit ​​part 204 engages with the box body 200. By engaging the first snap-fit ​​part 203 with the inner side of the outer cover 10 and the second snap-fit ​​part 204 with the box body 200, the outer cover 10 can be snapped between the cover body 202 and the box body 200. At this time, the voice component 20 can be set on the outer cover 10. The cover body 202 is connected by the first snap-fit ​​part 203 and the second snap-fit ​​part 204, which can solve the problem of the difficulty of setting fasteners and snap-fit ​​parts on the outer cover 10, improve assembly efficiency, and make the mold of the outer cover 10 simpler.

[0047] Thus, the outer cover 10 has mounting holes, and the cover body 202 is connected to a first snap-fit ​​part 203 and a second snap-fit ​​part 204. By snapping the first snap-fit ​​part 203 onto the inner side of the outer cover 10 and by snapping the second snap-fit ​​part 204 onto the box body 200, the voice component 20 can be set on the outer cover 10. This avoids installing the voice component 20 onto the panel by drilling holes, thus avoiding affecting the integrity of the indoor unit 1. In addition, it solves the problem of the difficulty of setting fasteners and snap-fit ​​parts on the outer cover 10, thereby improving assembly efficiency and making the mold of the outer cover 10 simpler.

[0048] In some specific embodiments of this utility model, the outer cover 10 is provided with an overlapping portion on the outside of the mounting hole, and the cover plate body 202 is disposed on the overlapping portion. The overlapping portion can connect with other components or limit the movement of other components by contacting them. When the cover plate body 202 is disposed on the overlapping portion, the overlapping portion can provide a stable support surface for the cover plate body 202, which can realize the stable installation of the cover plate body 202 and the precise positioning of the cover plate body 202, thereby improving the reliability of the cover plate body 202. Thus, the voice component 20 can be disposed on the outer cover 10.

[0049] In some specific embodiments of this utility model, such as Figure 10As shown, the first snap-fit ​​portion 203 is provided with a guide portion 205. The cross-sectional area of ​​the guide portion 205 gradually decreases in the direction from the outside of the housing to the inside of the housing. The guide portion 205 can play a guiding and limiting role. The gradual decrease in the cross-sectional area of ​​the guide portion 205 in the direction from the outside of the housing to the inside of the housing facilitates the pre-snap of the first snap-fit ​​portion 203 to the inner side of the outer cover 10, thereby pre-fixing the cover body 202 to the outer cover 10.

[0050] In some specific embodiments of this utility model, such as Figure 4 As shown, the housing 200 is provided with a third latching part 206, and the second latching part 204 latches onto the third latching part 206. The third latching part 206 can perform a latching function and can latch and cooperate with other components. The second latching part 204 and the third latching part 206 can latch and cooperate, so that the cover 201 and the housing 200 can be latched and cooperate, so that the housing 200 can abut against the inner side of the outer cover 10, thereby enabling the voice component 20 to be placed on the outer cover 10.

[0051] In some specific embodiments of this utility model, such as Figure 4 and Figure 10 As shown, the second snap-fit ​​part 204 is provided with a first guide slope 207, and the third snap-fit ​​part 206 is provided with a second guide slope 208. When the box body 200 and the cover plate 201 are assembled, the first guide slope 207 and the second guide slope 208 cooperate. Both the first guide slope 207 and the second guide slope 208 can serve as guides and limiters. When the box body 200 is assembled with the cover plate 201, the first guide slope 207 and the second guide slope 208 cooperate. In this way, when the second locking part 204 and the third locking part 206 are engaged, the second locking part 204 and the third locking part 206 can achieve more precise automatic alignment, greatly reducing the risk of misalignment. Secondly, the contact area between the first guide slope 207 and the second guide slope 208 is larger, and the pressure distribution is more uniform. In addition, even if there is a slight positional deviation between the second locking part 204 and the third locking part 206, the first guide slope 207 and the second guide slope 208 can automatically correct it by sliding against each other, making it more fault-tolerant.

[0052] In some specific embodiments of this utility model, such as Figure 4 , Figure 7 and Figure 8As shown, the voice component 20 also includes a voice element 209, which is connected to the side of the cover body 202 adjacent to the outer cover 10. The voice element 209 enables voice interaction. Its connection to the cover body 202 near the outer cover 10 allows it to be closer to the user's voice, reducing sound attenuation and interference during internal propagation, thus improving voice recognition sensitivity and accuracy. Furthermore, it is positioned away from the fan and duct, minimizing the impact of airflow noise on sound pickup. Additionally, when replacing or repairing the voice function, only the cover body 202 needs to be removed, eliminating the need to disassemble the entire voice component 20, improving after-sales efficiency. Moreover, the cover body 202 has an installation space within which the voice element 209 is installed, allowing for efficient use of the cover body 202's space and reducing space occupancy, thereby solving the space arrangement problem of the voice component 20.

[0053] In some specific embodiments of this utility model, such as Figure 9 As shown, a flexible arm 210 is provided on the side of the housing 200 facing the cover body 202, and the flexible arm 210 presses against the voice component 209. The flexible arm 210 makes the setting of the voice component 209 more stable, and can prevent the voice component 209 from loosening or the gap between the voice component 209 and the cover body 202 from generating resonance that affects the sound quality. The flexible arm 210 presses against the voice component 209, and can provide flexible pressing to connect the voice component 209 to the cover body 202, which can prevent the voice component 209 from loosening. At the same time, the flexible arm 210 can absorb vibration, which can prevent the gap between the voice component 209 and the cover body 202 from generating resonance that affects the sound quality of the voice component 209. By pressing the voice component 209 with the flexible arm 210, the assembly of the voice component 209 and the cover body 202 can be simplified and the voice component 209 can have a good effect.

[0054] In some specific embodiments of this utility model, such as Figure 7 and 10 As shown, a limiting protrusion 211 is provided on the side of the cover body 202 adjacent to the outer cover 10, and the limiting protrusion 211 limits the position of the voice component 209. The limiting protrusion 211 can be provided on the side of the cover body 202 adjacent to the outer cover 10, and the limiting protrusion 211 can play a limiting role. The limiting protrusion 211 can limit the position of the voice component 209, which can ensure that the voice component 209 is always in the optimal sound pickup position and avoid the decrease in recognition rate due to displacement. Secondly, the indoor unit 1 has fan vibration during operation, and the limiting protrusion 211 can prevent the voice component 209 from shifting or falling off due to long-term vibration, which can improve the reliability of the voice component 209. In addition, the limiting protrusion 211 can work in conjunction with the elastic arm 210, thereby realizing the six-degree-of-freedom omnidirectional limiting of the voice component 209.

[0055] In some specific embodiments of this utility model, such as Figure 7 and Figure 10 As shown, the voice component 20 also includes a connecting wire. A wiring groove 212 is provided on the side of the cover body 202 adjacent to the outer cover 10. One end of the connecting wire is connected to the voice component 209, and the other end of the connecting wire passes through the wiring groove 212 and is electrically connected to the control box. The connecting wire serves as a connector, enabling electrical connections between different components. The wiring groove 212 facilitates the wiring of the connecting wire in a fixed position. Both ends of the connecting wire are electrically connected to the voice component 209 and the control box, respectively. This enables the electrical connection between the voice component 20 and the control box. The voice component 20 can transmit voice signals to the control box through the electrical connection. At this time, the control box can parse the instructions, execute the operation, and then provide feedback on the result, thereby realizing the voice function of the indoor unit 1.

[0056] In some specific embodiments of this utility model, such as Figure 10 As shown, the cover plate body 202 has multiple through holes 213, which are spaced apart and positioned opposite to the voice component 209. The through holes 213 allow sound to pass through and release voice signals. The through holes 213 can be matched with the voice receiving point of the voice component 209. The spaced arrangement of the through holes 213 avoids interference between them and allows for a wider distribution range. To a certain extent, this also enables the voice component 20 to achieve voice control and status feedback. The positioning of the through holes 213 opposite to the voice component 209 means that the layout area of ​​the through holes 213 is directly opposite the receiving position of the voice component 209. In this case, the through holes 213 can form an unobstructed sound wave transmission path, thus improving the uniformity and directionality of sound pickup by the voice component 209.
