[0035] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0036] In the description of this utility model, "multiple" means two or more.

[0037] The indoor unit 1 of an air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0038] like Figures 1-10 As shown, the indoor unit 1 of the air conditioner according to an embodiment of the present invention includes: a housing 100, an indoor heat exchanger, and a fan assembly. The housing 100 includes an outer cover 120 and an air conditioning panel 110, which together define an installation cavity. The indoor heat exchanger is installed in the installation cavity. The fan assembly is installed in the installation cavity and is used to drive airflow through the indoor heat exchanger for heat exchange.

[0039] The voice module 200 is disposed within the housing 100 and corresponds to the position of the air conditioning panel 110. The voice module 200 includes a voice unit 210. The inner surface of the air conditioning panel 110 is constructed as a concave arc surface, and a sealing boss 310 protruding towards the voice unit 210 is formed on the inner surface of the air conditioning panel 110. The sealing boss 310 surrounds the voice unit 210 to form a voice channel, and the end face of the sealing boss 310 forms a sealing surface 311. The sealing surface 311 of the boss fits against the voice unit 210 to seal it.

[0040] For example, the indoor unit 1 of the air conditioner is a floor-standing air conditioner. The air conditioner panel 110 is located on the upper part of the front surface of the housing 100, such as above the air outlet. The voice module 200 is installed inside the air conditioner panel 110 and hidden inside the housing 100. The voice module 200 can be a MEMS (Micro-Electro-Mechanical Systems) microphone, and the voice unit 210 can be a MEMS chip used to receive or transmit voice. The side surface of the sealing boss 310 facing the voice module 200 is in contact with the voice module 200, that is, the side surface of the sealing boss 310 forms a plane and is in contact with the voice circuit board of the voice module 200. The sealing boss 310 and the air conditioner panel 110 form an integral structure, eliminating the need for additional positioning components between the air conditioner panel 110 and the voice module 200.

[0041] According to an embodiment of the present invention, the indoor unit 1 of the air conditioner has a sealing boss 310 forming a support for the voice module 200 on the air conditioner panel 110, and the end face of the sealing boss 310 forms a seal with the voice module 200. This provides support and a seal for the voice module 200. When the voice module 200 needs to be installed, it can be stably held on the inner side of the air conditioner panel 110 by the sealing boss 310, thus facilitating the positioning and installation of the voice module 200. The sealing boss 310 also provides some protection for the voice module 200, preventing damage during installation due to mismatch in the relative surface shapes of the voice module 200 and the air conditioner panel 110. After the voice module 200 is installed, it remains stable under the support and positioning effect of the sealing boss 310.

[0042] Furthermore, the sealing boss 310 surrounds the voice unit 210 to form a voice channel, matching the position of the voice unit 210 of the voice module 200 with the voice channel. The sealing surface 311 of the boss is also in close contact with the voice unit 210, creating a sound path between the voice unit 210 and the air conditioning panel 110. After the voice module 200 is installed, the air conditioning panel 110 remains in a position close to the user, allowing sound to propagate directly through the voice channel. This improves the clarity of sound transmission and enhances the user's interactive experience with the air conditioner indoor unit 1 using the voice module 200. For example, users can issue voice commands to control the air conditioner to turn on / off, adjust the temperature, etc., and the voice module 200 can announce information such as the set temperature, mode, airflow direction, and airflow speed of the air conditioner indoor unit 1.

[0043] Therefore, the indoor unit 1 of the air conditioner according to the embodiment of this utility model has the advantages of clear voice broadcast, high assembly stability, and convenient installation and positioning.

[0044] In some specific embodiments of this utility model, such as Figure 5 As shown, there are multiple voice units 210 and sealing bosses 310. The voice module 200 and the sealing bosses 310 correspond one-to-one with each other, and the sealing surfaces 311 of the multiple sealing bosses 310 are all formed on the same plane.

[0045] In some embodiments, such as Figure 7 As shown, the voice module 200 is constructed as a rectangle, with multiple voice units 210 spaced apart along the length of the voice module 200. For example, the voice units 210 are paired and located at both ends of the length of the voice module 200, and the sealing bosses 310 are paired and located on both sides of the curved surface of the air conditioning panel 110. The voice unit 210 at one end corresponds to the sealing boss 310 at one end, and the voice unit 210 at the other end corresponds to the sealing boss 310 at the other end.

[0046] Multiple voice units 210 can disperse the sound over a wider area, resulting in better sound production. Multiple sealing bosses 310 support and seal the voice units 210 at different positions, ensuring that each voice unit 210 forms an independent voice propagation path and guaranteeing the clarity of voice propagation.

[0047] In some specific embodiments of this utility model, such as Figure 8 As shown, the inner surface of the air conditioning panel 110 is also provided with a support rib 320 protruding towards the voice unit 210. The support rib 320 is located between adjacent sealing bosses 310. The surface of the support rib 320 facing away from the air conditioning panel 110 forms a support surface 321, which is suitable for supporting the voice unit 210.

[0048] Among them, the supporting surface 321 of the supporting rib 320 does not extend beyond the plane where the sealing surface 311 of the sealing boss 310 is located in the air conditioning panel 110.

[0049] For example, such as Figure 6 As shown, the sealing boss 310 protrudes further into the air conditioning panel 110 by a greater distance than the support rib 320 protrudes further into the air conditioning panel 110. When the voice module 200 is not under load, there is a certain gap between the voice module 200 and the support rib 320 (e.g., ...). Figure 6 As shown in d), when the voice module 200 deforms in the direction of the air conditioning panel 110 under force, it can also be supported by the support rib 320.

[0050] Understandably, the voice unit 210 is located on the circuit board of the voice module 200, which has a flat board structure. The voice module 200 is supported by the circuit board, the sealing boss 310, and the support rib 320. For example, the voice module 200 is mounted to the air conditioning panel 110 by fasteners. The fasteners apply pressure to the voice module 200 in the direction of the air conditioning panel 110, and the voice module 200 may deform under the force. The support surface 321 of the support rib extends into the air conditioning panel 110 without exceeding the plane of the sealing surface 311 of the sealing boss 310, so that the voice module 200 can be supported by the sealing boss 310 when under force, or simultaneously supported by the sealing boss 310 and the support rib 320, thereby maintaining stability.

[0051] Furthermore, the extension distance of the support rib 320 is less than the extension distance of the sealing boss 310, which ensures that the sealing boss 310 always supports and seals the voice module 200, guaranteeing good sealing between the voice unit 210 and the sealing boss 310. In addition, the support rib 320 also strengthens the curved air conditioning panel 110, improving the structural strength of the air conditioning panel 110.

[0052] In some specific embodiments of this utility model, such as Figure 9 As shown, the support ribs 320 are constructed in the shape of long strips and there are multiple support ribs 320 arranged in parallel, and the support surfaces 321 of the multiple support ribs 320 are formed on the same plane.

[0053] For example, the support ribs 320 extend along the height of the voice panel and are arranged parallel to each other in the horizontal direction. The middle support rib 320 extends a greater distance inward into the voice panel, while the support ribs on the sides extend a smaller distance inward, so that the support surfaces 321 of the multiple support ribs 320 are formed on the same plane. By having the support surfaces 321 of the multiple support ribs 320 on the same plane, support can be provided over a larger area of ​​the voice module 200, further improving the stability of the voice module 200 installation.

[0054] In some specific embodiments of this utility model, such as Figure 9 As shown, the air conditioning panel 110 is also constructed with a limiting rib 111 surrounding the voice module 200. The limiting rib 111 is constructed with a limiting edge 112 extending toward the central area of ​​the voice module 200. The edges of the voice circuit board are constructed with limiting notches 202 corresponding to the positions of the limiting edge 112. The limiting edge 112 is matched with the limiting notch 202.

[0055] The limiting rib 111 engages with the side of the voice module 200 to restrict its movement. The limiting rib 111 extends inward toward the air conditioning panel 110, positioning the voice module 200 within the air conditioning panel 110 to ensure it is installed in the correct position. For example, the limiting rib 111 may be located on two short sides and one long side of the voice module 200, partially surrounding the outside of the voice module 200 to restrict its movement.

[0056] The distance by which the limiting rib plate 111 extends into the air conditioning panel 110 is the same as or slightly exceeds the thickness of the voice module 200, so that the voice module 200 can be limited by the limiting rib plate 111 after installation.

[0057] Furthermore, the limiting rib 112 extends towards the center of the voice module 200, and by cooperating with the limiting notch 202 of the voice module 200, it can further restrict the movement of the voice module 200. Moreover, the cooperation between the voice module 200 and the limiting rib 111 is tighter, resulting in more precise positioning.

[0058] In some specific embodiments of this utility model, such as Figure 10As shown, the voice module 200 has a first voice hole 21 facing the air conditioner panel 110 at the corresponding position of the voice unit 210, and a second voice hole 11 penetrating the air conditioner panel 110 is constructed at the center of the sealing boss 310. The first voice hole 21 and the second voice hole 11 are coaxially arranged.

[0059] The first voice hole 21 is a countersunk hole, and the second voice hole 11 is a through hole, forming a voice channel. Both the first voice hole 21 and the second voice hole 11 are located in the area of ​​the voice unit 210, which facilitates the reception and transmission of voice, and makes it easier for sound to propagate at the front panel.

[0060] When the voice module 200 emits sound, the sound propagates sequentially through the first voice hole 21 and the second voice hole 11 out of the air conditioning panel 110, allowing the user to hear the announcements from the voice module 200 more clearly. When the user issues a voice command to the voice module 200, the user's voice propagates sequentially through the second voice hole 11 and the first voice hole 21 to the voice module 200, thereby improving the interaction between the voice module 200 and the user.

[0061] Furthermore, such as Figure 10 As shown, the diameter of the first voice hole 21 is smaller than the diameter of the second voice hole 11. By setting the diameter of the first voice hole 21 to be smaller and the diameter of the second voice hole 11 to be larger, the sound emitted by the voice module 200 gradually increases in its outward propagation range, which meets the requirements for sound propagation.

[0062] In some specific embodiments of this utility model, such as Figure 4 and Figure 7 As shown, the indoor unit 1 of the air conditioner also includes a mounting plate 400, which is mounted on the air conditioner panel 110 and abuts against one side of the voice module 200 facing away from the sealing boss 310. Specifically, the mounting plate 400 abuts against the voice module 200, so that the voice module 200 is clamped between the mounting plate 400 and the pad 300.

[0063] In this design, the area of ​​the mounting plate 400 is larger than that of the voice module 200 in the installation direction, so that the pad 300 and the voice module 200 are enclosed by the mounting plate 400, reducing the exposure of the voice module 200 and minimizing its susceptibility to dust. It is understood that the mounting plate 400 does not necessarily have to be a plate-shaped structure; it only needs to match the shape of the voice module 200. The mounting plate 400 is fixed to the air conditioning panel 110 using fasteners.

[0064] Furthermore, such as Figure 3 and Figure 6 As shown, the mounting plate 400 has a receiving groove 401 on the side facing the voice module 200, and the voice module 200 is received in the receiving groove 401.

[0065] The mounting plate 400 constructs a receiving groove 401, allowing the voice circuit board 210 to be placed in a relatively enclosed environment. The opposite sides of the voice circuit board 210 are respectively enclosed by the pad 300 and the mounting plate 400, providing good dust protection. For example, the mounting plate 400 has ribs formed within the receiving groove 401, which press the voice circuit board 210 and the pad 300 firmly against the air conditioning panel 110.

[0066] According to a second aspect of the present invention, the indoor unit 1 of the air conditioner includes: a housing 100, an indoor heat exchanger, and a fan assembly.

[0067] The housing includes an outer cover 120 and an air conditioning panel 110, which together define a mounting cavity. An indoor heat exchanger is installed within the mounting cavity. A fan assembly is also installed within the mounting cavity to drive airflow through the indoor heat exchanger for heat exchange.

[0068] The indoor unit 1 of the air conditioner also includes a voice module 200, which is disposed inside the housing and corresponds to the position of the air conditioner panel 110. The voice module 200 includes a voice unit 210. The inner surface of the air conditioner panel is constructed as a concave arc surface, and the inner surface of the air conditioner panel is constructed with a sealing boss 310 protruding towards the voice unit 210. The voice units 210 are arranged in pairs on both sides of the voice module 200. The sealing bosses 310 are arranged in pairs and correspond to the position of the voice units 210. The end face of the sealing boss 310 forms a sealing surface 311, and the sealing surface 311 of the sealing boss 310 fits against the voice unit 210 to seal it.

[0069] According to the embodiment of this utility model, in the indoor unit 1 of the air conditioner, the sealing boss 310 and the voice unit 210 are paired and arranged on both sides of the voice module 200. The areas for emitting and receiving voice are relatively dispersed, resulting in good voice broadcasting and reception effects. The sealing boss 310 and the voice unit 210 are positioned correspondingly, providing good support and sealing. They also provide some protection for the voice module 200, preventing damage during installation due to mismatch in the relative surface shapes of the voice module 200 and the air conditioner panel 110. After the voice module 200 is installed, it remains stable under the support and positioning of the sealing boss 310.

[0070] Furthermore, the sealing boss 310 surrounds the voice unit 210 to form a voice channel, so that the voice unit 210 of the voice module 200 is matched with the voice channel. Through the sealing surface 311 of the boss and the voice unit 210, a sound path is formed between the voice unit 210 and the air conditioning panel 110.

[0071] Therefore, the indoor unit 1 of the air conditioner according to the embodiment of this utility model has the advantages of clear voice broadcast, high assembly stability, and convenient installation and positioning.

[0072] Other components and operations of the indoor unit 1 of the air conditioner according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0073] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0074] The compressor compresses the refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0075] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0076] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in either the indoor or outdoor unit.

[0077] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.
