The main body of this embodiment is an air conditioner, which includes an indoor unit and an outdoor unit. Referring to fig. 1, a casing 1000 of the indoor unit, specifically, a panel structure is provided with an installation structure for installing a microphone 3000, so that the air conditioner can implement a voice control function.

Please refer to fig. 4 and fig. 5, which are schematic cross-sectional views of the mounting structure, respectively.

It can be seen that, in the present embodiment, the mounting structure specifically includes:

a mounting base 2100 connected to the housing 1000 and having a mounting hole 2110 for receiving the microphone 3000, the mounting hole 2110 having an opening end 2111;

an elastic sealing member 2200 attached to the mounting base 2100 and closing the open end 2111, as shown in fig. 5 and 6, the elastic sealing member 2200 including a first portion 2210 surrounding the open end 2111 and attached to an end surface of the open end 2111;

a pressing member 2300 abutting on the elastic sealing member 2200 on the side facing away from the mounting base 2100;

and a locking mechanism for driving the pressing member 2300 to press the elastic sealing member 2200 so that the first portion 2210 is brought into sealing contact with the end surface of the open end 2111 by the pressing member 2300.

In the present embodiment, an elastic sealing member 2200 for closing the open end 2111 is provided mainly at the open end 2111 of the mounting hole 2110. The pressing member 2300 can press the elastic sealing member 2200 under the driving of the locking mechanism, so that the first portion 2210 surrounding the open end 2111 and connected to the end surface of the open end 2111 in the elastic sealing member 2200 is in mutual pressing contact with the end surface of the open end 2111 to form a seal, thereby preventing external liquid from flowing into the mounting hole 2110 along the end surface of the open end 2111, further improving the sealing effect of the mounting structure on the end surface of the open end 2111 and improving the operation reliability of the microphone 3000.

It should be noted that, in the present embodiment, the elastic sealing member 2200 is specifically a rubber sheet having a certain elasticity, and after the first portion 2210 and the end surface of the open end 2111 are pressed against each other, the first portion 2210 is deformed to a certain extent to be in close contact with the end surface of the open end 2111, and thus liquid is hindered from moving along the gap between the first portion 2210 and the end surface of the open end 2111. In addition, in the present embodiment, the pressing member 2300 is configured in a cover shape. Of course, the practitioner can select a specific shape of the above-described pressing member 2300 without affecting the object of the invention.

Further, with the microphone 3000, vibrations that are unavoidable during operation of the air conditioner tend to cause looseness between the microphone 3000 and the mounting structure. Therefore, in the present embodiment, as illustrated in fig. 4 and 5, the microphone 3000 is in interference fit with the inner wall of the mounting hole 2110. However, even with this arrangement, the microphone 3000 may shake randomly along the axial direction of the mounting hole 2110 with respect to the mounting base 2100 due to the vibration of the air conditioner, which may affect the sound-receiving effect of the microphone 3000.

Therefore, how to improve the mounting stability of the microphone 3000 in the mounting structure is of great significance.

In this regard, as shown in fig. 4, 5 and 6, in the present embodiment, an abutting surface 2112 is provided at an end of the mounting hole 2110 opposite to the opening end 2111, and the elastic sealing member 2200 includes a second portion 2220 extending to an inner side of the hole of the opening end 2111, the second portion 2220 being used for abutting and pressing the microphone 3000 by the pressing member 2300, so that the microphone 3000 abuts against the abutting surface 2112.

Here, the elastic sealing member 2200 described above can also play a role of a stopper for pressing the microphone 3000 so that the microphone 3000 is tightly abutted on the mounting base 2100, in addition to the role of closing the open end 2111. By the above arrangement, the case 1000 to which the microphone 3000 and the mounting base 2100 are connected is substantially fixed, thereby securing the sound-collecting effect of the microphone 3000. In addition, as described above, the elastic sealing member 2200 has certain elasticity, and the elastic sealing member 2200 and the abutting surface 2112 abut against the opposite sides of the microphone 3000, respectively, and the elastic sealing member 2200 is elastically contacted with the microphone 3000 by the pressing member 2300. The elastic sealing member 2200 can allow the microphone 3000 to move to some extent along a side close to the elastic sealing member 2200 when the microphone 3000 is shaken in the axial direction of the mounting hole 2110. Compared with the scheme that the two opposite sides of the microphone 3000 are respectively and rigidly abutted by the limiting member, the technical scheme provided by the embodiment can effectively reduce the risk that the microphone 3000 is damaged. It should be noted that, in this embodiment, the stopping surface 2112 is further provided with a sound receiving hole penetrating through the panel for receiving sound by the microphone 3000.

More specifically, the surface of the pressing member 2300 contacting the elastic sealing member 2200 may be configured to be in contact with the surface of the elastic sealing member 2200. In this embodiment, however, the elastic sealing member 2200 is uniformly or substantially uniformly pressed throughout by the pressing member 2300. The elastic sealing member 2200 is hardly compressed to a small thickness. Liquid may intrude into the interior of the resilient sealing member 2200 through the exposed side of the first portion 2210, through the tiny holes in the resilient sealing member 2200 itself, and finally reach into the mounting hole 2110.

As shown in fig. 4 and 5, in the present embodiment, the pressing member 2300 includes a first pressing portion 2310 and a second pressing portion 2320, the first pressing portion 2310 abuts on the first portion 2210, and the second pressing portion 2320 abuts on the second portion 2220, wherein the first pressing portion 2310 protrudes toward the side close to the elastic sealing member 2200 with respect to the second pressing portion 2320, so that the first portion 2210 is compressively deformed toward the side close to the end surface of the open end 2111 with respect to the second portion 2220.

Referring to fig. 4, 5 and 6, fig. 6 shows the elastic sealing member 2200 in an uninstalled state, since the first pressing portion 2310 and the second pressing portion 2320 of the pressing member 2300 are in a staggered shape with a certain height difference, during the installation process of the pressing member 2300 and the elastic sealing member 2200 in a gradual contact manner, the first pressing portion 2310 first contacts the first portion 2210 and drives the first portion 2210 to be compressed and deformed toward the end surface side near the open end 2111 relative to the second portion 2220.

The second pressing portion 2320 comes into contact with the second part 2220 and compresses the second part 2220 after the first part 2210 is compressively deformed by a predetermined degree along the end surface side near the open end 2111. After installation, the entire resilient sealing member 2200 takes on a form in which the first portion 2210 is thinner and the second portion 2220 is thicker.

Here, by providing the first pressing portion 2310 and the second pressing portion 2320, the first portion 2210 can be more strongly compressed than the second portion 2220, the first portion 2210 becomes denser due to the compression and the area of the side portion thereof exposed is reduced, thereby blocking the intrusion of liquid into the elastic sealing member 2200 through the side portion of the first portion 2210 exposed.

Further, in order to ensure that the first pressing portion 2310 can uniformly press the first part 2210, in the present embodiment, the first pressing portion 2310 is an annular structure surrounding the open end 2111. Of course, the practitioner may also provide the first pressing portion 2310 in an intermittent shape extending in a direction around the open end 2111 without affecting the object of the invention.

Further, in the present embodiment, the pressing member 2300 includes the butting portion 2330, the butting portion 2330 has a cylindrical shape with one end open, the mounting base 2100 at least partially extends into the butting portion 2330, and the open end 2111 is located in the butting portion 2330. The docking portion 2330 can accommodate the open end 2111 within a relatively closed space, further reducing the risk of liquid erosion of the microphone 3000.

In addition, referring to fig. 4 and 5, in the present embodiment, an annular protrusion 2331 is formed on the inner wall of the butting portion 2330, and the protrusion 2331 is located on the side of the end surface of the opening end 2111, which is opposite to the elastic sealing member 2200. Since the protrusion 2331 protrudes from the inner wall of the docking portion 2330 toward the side of the mounting base 2100, the minimum distance from the inner wall of the docking portion 2330 to the mounting base 2100 is effectively reduced, so that it is more difficult for external liquid to enter into the open port of the docking portion 2330.

However, the distance from the inner wall of the docking portion 2330 to the mounting base 2100 is reduced, and the manufacturing accuracy of the mounting base 2100 and the docking portion 2330 is increased. In this regard, as shown in fig. 5, in the present embodiment, the inner side surface of the protrusion 2331 includes a first annular surface 2332, the inner diameter of the first annular surface 2332 gradually decreases in a direction toward the end surface of the open end 2111, and the inner side surface of the protrusion 2331 includes a second annular surface 2333, the inner diameter of the second annular surface 2333 gradually increases in a direction toward the end surface of the open end 2111, and the second annular surface 2333 is disposed on a side of the first annular surface 2332 toward the end surface of the open end 2111 and is connected to the first annular surface 2332. Since the first annular surface 2332 and the second annular surface 2333 are provided, the minimum distance between the mounting base 2100 and the inner wall of the docking portion 2330 is reduced, and compared with the technical scheme that the inner side surface of the protrusion 2331 always keeps a small fixed distance from the mounting base 2100, the technical scheme provided by the embodiment can facilitate the mounting base 2100 to extend into the docking portion 2330, and reduce the requirement on the manufacturing accuracy of the mounting base 2100 and the docking portion 2330.

As for the above locking mechanism, the locking mechanism is mainly used to drive the pressing member 2300 to press the elastic sealing member 2200. In this embodiment, referring to fig. 2, fig. 3 and fig. 4, the locking mechanism includes a first locking body 2410 and a second locking body 2420, the first locking body 2410 and the second locking body 2420 can move toward or away from each other, the second locking body 2420 and the mounting base 2100 are fixed to each other, the pressing member 2300 is disposed between the first locking body 2410 and the second locking body 2420 and abuts against the first locking body 2410, and the second locking body 2420 is located on a side of the pressing member 2300 close to the elastic sealing member 2200.

When the first locking body 2410 and the second locking body 2420 move toward each other, the first locking body 2410 abuts against the pressing member 2300 and the second locking body 2420 is located on the side of the pressing member 2300 close to the elastic sealing member 2200, so that the first locking body 2410 applies a locking force to the pressing member 2300. This locking force causes the pressing member 2300 to have a tendency toward the end surface side near the open end 2111, thereby causing the pressing member 2300 to press the elastic sealing member 2200.

In this embodiment, a thread pair is formed between the first locking body 2410 and the second locking body 2420, an external thread is formed on the first locking body 2410, an internal thread matched with the external thread is formed on the second locking body 2420, and the first locking body 2410 and the second locking body 2420 are in threaded connection, so that the two can move towards or away from each other, and the two can be kept locked at any position in the moving direction towards or away from each other.

More specifically, in the present embodiment, the locking mechanism includes a screw, a head of the screw forms the first locking body 2410, the second locking body 2420 is a connection post connected to the housing 1000 and provided with a threaded hole, and a threaded end of the screw passes through the pressing member 2300 and is connected to the second locking body 2420.

It is worth mentioning that, as shown in fig. 2 and 3, in the present embodiment, the number of the mounting base 2100, the elastic sealing member 2200 and the pressing member 2300 described above is two, the number of the locking mechanism is one, the pressing member 2300 is in particular in an arm shape, one ends of the pressing members 2300 in the two sets, which are away from the elastic sealing member 2200, are connected to each other, and the two sets of the mounting base 2100, the elastic sealing member 2200 and the pressing member 2300 are symmetrically disposed around the connecting portion of the two sets of the pressing members 2300. The locking mechanism acts on the connecting portion of the two sets of pressing members 2300, so that the pressing members 2300 on both sides can simultaneously press and compress the corresponding elastic sealing member 2200 by the locking mechanism. The number of components of the locking mechanism can be reduced.

Further, the pressing member 2300 may be configured to have a certain elastic deformation capability. In this manner, the locking force applied by the locking mechanism can be better transmitted to the resilient sealing member 2200. For example, in the present embodiment, the pressing member 2300 has elasticity, and in an uninstalled state, an angle between an extending direction of the arm-shaped pressing member 2300 and a vertical direction is about 95 degrees. Under the action of the locking mechanism, the extrusion member 2300 deforms elastically, and the included angle between the extension direction and the vertical direction changes from 0.5 ° to 1 °. The end of the pressing member 2300 remote from the locking mechanism has a tendency to undergo elastic recovery deformation. At this time, the first pressing portion 2310 and the second pressing portion 2320 press and compress the elastic sealing member 2200. In addition, in the present embodiment, the amount of compressive deformation of the second portion 2220 in the elastic sealing member 2200 is about 0.5 mm.
