The present invention is proposed as an air conditioning indoor unit. As shown in FIG. 4, the air-conditioning indoor unit includes an outside air introduction module 40, and the outside air introduction module 40 is used for introducing outside air into a room (sending outside air into the room) in a closed indoor space. By continuously supplying fresh air, the oxygen concentration in the indoor air is increased and air conditioning diseases are reduced. Optionally, the outside air introduction module can also be used to expel indoor air.

Optionally, the outside air introduction module includes an outside air introduction shell (not shown) mounted inside the housing of the indoor unit and an outside air introduction fan assembly (not shown) mounted inside the outside air introduction shell. The outside air introduction shell is provided with an outside air suction port and an outside air outlet, the outside air suction port is communicated with the outside, the outside air outlet is communicated with the room, and the outside air suction port and the outside air outlet are communicated with each other. The outside air introduction fan assembly is located between the outside air inlet and the outside air outlet to provide power for the flow of outside air.

It can be understood that the air-conditioning indoor unit is a floor-standing type, a ceiling-suspended type, a wall-mounted air-conditioning indoor unit, a vertical wall-mounted air-conditioning indoor unit, or the like. The wall-mounted air conditioner indoor unit will be described below as an example, but the present invention is not limited to the wall-mounted air conditioner indoor unit.

In one embodiment of the present invention, as shown in FIGS. 1 to 3, 17, 18, 20, and 21, the air conditioner indoor unit 100 has a housing 10 provided with an outside air introduction port 111. The outside air introduction panel assembly 20 is provided with the blowout structure 211, attached to the housing 10, and the blowout structure 211 is provided corresponding to the outside air introduction port 111.

Specifically, the outside air introduction port 111 is an outlet for outside air. The outside air introduction panel assembly 20 is attached to the housing 10 and can be covered with the outside air introduction port 111 to realize dustproofness. Moreover, by installing the blowout structure 211 corresponding to the outside air introduction port 111 in the outside air introduction panel assembly 20, the introduced outside air is processed and various needs of the user are realized.

In a specific embodiment, as shown in FIG. 2, the blowout structure 211 has a diffusion blowout micropore structure, that is, a plurality of diffusion blowout micropores arranged at intervals in the outside air introduction panel assembly 20. The diffusion blowout micropores penetrate the outside air introduction panel assembly 20). As a result, the user experience can be improved by realizing windless cooling. Alternatively, the blowout structure 211 may have a blowout grill structure (not shown). As a result, it is possible to realize blowing out and further reduce the manufacturing difficulty and manufacturing cost of the outside air introduction panel assembly 20. Of course, the balloon structure 211 can be provided as another structural form according to actual needs, and will not be described further here.

Specifically, the housing 10 includes an integrated panel 11, the outside air introduction port 111 is provided on the integrated panel 11, and the outside air introduction panel assembly 20 is attached to the integrated panel 11.

The present invention improves the structural form of the outside air introduction panel assembly 20 itself and the mounting method thereof, but of course, the improvements of the two aspects can also be combined with each other. Specifically, regarding the outside air introduction panel assembly 20, the outside air introduction panel assembly 20 is installed as an integrally molded structure and the structure is directly attached to the housing 10, or the outside air introduction panel assembly 20 is The outside air introduction panel 21 and / or the outside air introduction panel 21 are attached to the mounting plate 22, and the mounting plate 22 and / or the outside air introduction panel 21 is attached to the housing 10, including the outside air introduction panel 21 and the mounting plate 22 provided separately. Regarding the mounting method of the outside air introduction panel assembly 20, the outside air introduction panel assembly 20 is installed so as to be openable and closable at the outside air introduction port 111, or the outside air introduction panel assembly 20 is removed from the outside air introduction port 111. It can be installed with a lid impossible. In the following, explanations will be given individually or in combination.

It should be mentioned here that the outside air introduction panel assembly 20 can be installed as a regular shape structure such as a rectangular structure, a square structure, or a waist-shaped structure, so that the outside air introduction panel assembly 20 is designed, manufactured, and manufactured. Assembling can be facilitated. Naturally, the outside air introduction panel assembly 20 can also be installed as a structure having an irregular shape.

In order to facilitate the description of the snap-fit structure between the outside air introduction panel 21 and the mounting plate 22, the outside air introduction panel assembly 20 will be described below as a rectangular structure or a substantially rectangular structure. Optionally, the outside air introduction panel 21 and the mounting plate 22 in the following have a rectangular structure or a substantially rectangular structure.

Hereinafter, the situation in which the outside air introduction panel assembly 20 includes the outside air introduction panel 21 and the mounting plate 22 separately provided will be specifically described.

Further, as shown in FIGS. 4 and 5, the outside air introduction panel assembly 20 includes an outside air introduction panel 21 provided with the blowout structure 211 and a mounting plate 22. The outside air introduction panel 21 is attached to the surface of the mounting plate 22, the mounting plate 22 is provided with a vent 221 penetrating the mounting plate 22, and the vent 221 is arranged corresponding to the blowout structure 211. Since the vent 221 allows outside air to pass through, the influence of the mounting plate 22 on the outside air can be avoided.

In the manufacturing process, the outside air introduction panel assembly 20 has not yet reached the standard in appearance after the initial manufacturing stage (for example, after mold release) and cannot be directly applied to the product. Therefore, in order to satisfy the design requirements, it is necessary to perform different process processes on various parts of the outside air introduction panel assembly 20. For example, it is necessary to apply a spray coating treatment to the inner and outer surfaces of the outside air introduction panel assembly 20 and to perform an electroplating treatment on the peripheral edge thereof. In the present invention, by providing the outside air introduction panel 21 and the mounting plate 22 separately assembled, the outside air introduction panel 21 can be spray-painted and the mounting plate 22 can be electroplated. Optionally, the surface of the outside air introduction panel 21 is spray-painted, for example, the surface of the outside air introduction panel 21 is spray-painted with elegance gold, and the peripheral edge of the mounting plate 22 is electroplated, for example, the mounting plate 22. The periphery is treated with Mocha Gold electroplating.

The present invention is provided as an outside air introduction panel assembly 20 including an outside air introduction panel 21 and a mounting plate 22 which are separately connected and provided, whereby the outside air introduction panel 21 and the mounting plate 22 are subjected to different process treatments. It should be understood that the machining process of the outside air introduction panel assembly 20 can be simplified and the production efficiency can be improved while satisfying different design requirements.

Here, it should be mentioned that when the outside air introduction panel assembly 20 including the outside air introduction panel 21 and the mounting plate 22 provided separately connected to each other is provided, the outside air introduction panel assembly 20 is the outside air introduction port 111. It may be installed so as to be openable and closable, or it may be provided with a non-removable (for example, welding) lid on the outside air introduction port 111.

Of course, in other improvements, the outside air introduction panel assembly 20 can be provided as an integrally arranged structure.

Further, the outside air introduction panel 21 is installed along the surface of the mounting plate 22 toward the surface of the mounting plate 22. As a result, the gap between the outside air introduction panel 21 and the mounting plate 22 can be made very small, and further, by eliminating the gap, it is possible to prevent the generation of abnormal noise due to wind leakage.

Further, as shown in FIGS. 3 to 5, the outside air introduction panel 21 is attached to the outer surface of the mounting plate 22. The outer surface of the mounting plate 22 refers to the surface of the mounting plate 22 opposite to the surface facing the housing 10, and conversely, the inner surface of the mounting plate 22 refers to the housing 10 of the mounting plate 22. Point to the side facing. Similarly, the outer surface of the outside air introduction panel 21 refers to the surface of the outside air introduction panel 21 opposite to the surface facing the housing 10, and conversely, the inner surface of the outside air introduction panel 21 is the outside air introduction. Refers to the surface of the panel 21 facing the housing 10.

Therefore, by attaching the outside air introduction panel 21 to the outer surface of the mounting plate 22, the blowing structure 211 is located outside the vent 221 and the blowing structure 211 facilitates sending air into the room.

Further, as shown in FIGS. 4, 5 and 7, the mounting plate 22 includes a base material 222 and a decorative side plate 223 provided on the outer surface of the base material 222, and the vent 221 is a base material. The outside air introduction panel 21 is provided on the outer surface of the base material 222, and the outside air introduction panel 21 is located inside the decorative side plate 223. The inside of the decorative side plate 223 refers to the side of the decorative side plate 223 toward the center of the base material 222.

In this way, the mounting plate 22 includes the base material 222 and the decorative side plate 223 provided on the outer surface of the decorative plate, so that the mounting space can be defined between the base material 222 and the decorative side plate 223. it can. The outside air introduction panel 21 can be protected by attaching the outside air introduction panel 21 to the outer surface of the base material 222, positioning it inside the decorative side plate 223, and mounting the outside air introduction panel 21 in the mounting space.

Specifically, the decorative side plate 223 is provided on the edge of the base material 222. Therefore, it helps to reduce the size of the mounting plate 22.

Specifically, the side edge of the outside air introduction panel 21 is arranged near or adjacent to the decorative side plate 223. In this way, by improving the compactness of the assembly of the outside air introduction panel 21 and the mounting plate 22, the rationality of the design can be improved, that is, the outside air introduction panel assembly 20 can be miniaturized and rational. The design can be realized.

Specifically, the decorative side plate 223 can be electroplated. By installing the decorative side plate 223 in this way, the peripheral edge of the mounting plate 22 can be easily electroplated, and the plating effect can be easily exhibited.

Further, as shown in FIG. 5, the outside air introduction panel 21 and the mounting plate 22 are connected by a snap-fit structure. In general, the snap-fit structure is easy to process and does not damage the structure of the outside air introduction panel assembly 20 itself. Moreover, by designing the snap-fit structure, the snap-fit structures can be fitted to each other, and the desired connection effect can be easily achieved. Moreover, assembling the snap-fit structure is easy, convenient and robust.

Hereinafter, the snap-fit structure between the outside air introduction panel 21 and the mounting plate 22 will be described in detail. It should be understood that the snap-fit structure between the outside air introduction panel 21 and the mounting plate 22 is not limited to this.

Specifically, as shown in FIGS. 4 to 6, a locking projection 212 is provided on the inner surface of the outside air introduction panel 21, a locking hole 224 is provided in the mounting plate 22, and the locking projection 212 is provided. Is engaged in the locking hole 224. Therefore, the initial mounting / positioning of the outside air introduction panel 21 and the mounting plate 22 can be realized through the engagement between the locking projection 212 and the locking hole 224.

Further, as shown in FIGS. 5 and 6, the locking projections 212 are a connecting projection 2121 projecting from the inner surface of the outside air introduction panel 21 and a limiting projection 2122 projecting laterally from the connecting projection 2121. The limiting projection 2122 is provided so as to face the outside air introduction panel 21, and a latch groove 2123 is defined between the connecting projection 2121, the limiting projection 2122, and the outside air introduction panel 21. As shown in FIGS. 5, 6 and 9, a latch protrusion 2241 is projected from the inner side wall of the locking hole 224, and a mounting gap 2242 is formed between the latch protrusion 2241 and the inner side wall of the locking hole 224. It is formed and the latch projection 2241 is engaged with the latch groove 2123. The mounting gap 2242 is used to pass the locking projection 212.

Specifically, the latch groove 2123 has an inlet. As shown in FIG. 6, when mounting the outside air introduction panel 21 and the mounting plate 22, the locking projection 212 is first inserted into the mounting gap of the locking hole 224, and then the outside air introduction panel 21 and the mounting plate 22 are moved. The latch protrusion 2241 is moved into the latch groove 2123 via the inlet of the latch groove 2123. At this time, the limiting protrusion 2122 can engage the outside air introduction panel 21 and the mounting plate 22 by limiting the movement of the latch protrusion 2241.

Therefore, with the above structural arrangement, the outside air introduction panel 21 and the mounting plate 22 can be easily and conveniently connected.

Further, as shown in FIG. 6, the locking projection 212 further includes a reinforcing projection 2124 projecting from the inner surface of the outside air introduction panel 21, and the reinforcing projection 2124 includes a limiting projection 2122 and an outside air introduction panel 21. It is connected. Therefore, the structural strength of the locking projection 212 can be increased through the installation of the reinforcing projection 2124, so that the bonding strength and stability between the outside air introduction panel 21 and the mounting plate 22 can be increased.

Further, as shown in FIGS. 5 and 6, the reinforcing projection 2124 is provided in the extending direction of the latch projection 2241. Therefore, the reinforcing projection 2124 can play a role of positioning with respect to the attachment of the latch projection 2241.

Further, as shown in FIGS. 5 and 6, a plurality of the locking projections 212 are provided, a plurality of the locking holes 224 are also provided corresponding to the plurality of locking projections 212, and a plurality of the plurality of locking projections 212 are provided. Correspondingly engaged in each of the locking holes 224 of the. In this way, the bonding strength and stability between the outside air introduction panel 21 and the mounting plate 22 can be further enhanced.

Further, the locking projections 212 may be arranged regularly, thus facilitating the design and manufacture of the outside air introduction panel 21.

Further, as shown in FIGS. 5 and 6, the locking projections 212 are provided in two rows. It can be seen that the greater the number of the locking projections 212, the greater the difficulty in manufacturing the outside air introduction panel 21. Therefore, through the installation of the two rows of locking projections 212, the bonding strength and stability between the outside air introduction panel 21 and the mounting plate 22 can be ensured, and waste and an increase in manufacturing difficulty can be avoided. Of course, the locking projections 212 can also be designed in other regular arrangements.

Further, the two rows of locking projections 212 are provided on both opposite sides of the outside air introduction panel 21, respectively. In this way, it is possible to prevent the locking projection 212 from interfering with other structures such as the blowout structure 211, thereby facilitating the miniaturization design of the outside air introduction panel 21.

Specifically, the two rows of locking projections 212 are provided on both long sides of the outside air introduction panel 21, respectively. Similarly, the locking holes 224 are also provided in two rows, and are arranged on both long sides of the mounting plate 22. In this way, by providing the snap-fit structure of the locking projection 212 and the locking hole 224 on the long side of the outside air introduction panel assembly 20, the long side of the outside air introduction panel 21 and the long side of the mounting plate 22 Since the bond strength and stability of the outside air can be easily improved, it is advantageous to improve the bond strength and stability of the outside air introduction panel 21 and the mounting plate 22.

It should be understood that the orientation of the inlets of latch grooves 2123 defined by the plurality of locking projections 212 must match to ensure assembly consistency, thereby simplifying the assembly process. ..

Further, the latch projection 2241 extends in the length direction of the outside air introduction panel assembly 20. In this way, when the outside air introduction panel 21 and the mounting plate 22 are relatively moved in the length direction of the outside air introduction panel assembly 20, the latch projection 2241 passes through the inlet of the latch groove 2123 and enters the latch groove 2123. You can move. Of course, the latch projection 2241 can also be extended in other directions.

Further, as shown in FIGS. 5 to 8 and 11 to 16, a retreat prevention protrusion 213 is provided on either the inner surface of the outside air introduction panel 21 or the outer surface of the mounting plate 22, and the other. Is provided with a retreat prevention recessed groove 225, and the retreat prevention protrusion 213 is inserted into the retreat prevention recessed groove 225. By providing the retreat prevention protrusions 213 and the retreat prevention recessed grooves 225 that are fitted to each other in this way, it is possible to prevent the outside air introduction panel 21 and the mounting plate 22 from moving in opposite directions, so that the locking protrusions 212 are engaged. It can be prevented from coming off from the blind hole 224.

In a specific embodiment, it is understood that the thickness of the outside air introduction panel 21 and the mounting plate 22 are both thin, the structural strength of the members such as the snap-fit structure on the panel is weak, and they are easily damaged when repeatedly removed. I want to. Therefore, when the snap-fit structure between the outside air introduction panel 21 and the mounting plate 22 is designed as a structure that can be easily removed, the user tends to damage the outside air introduction panel assembly 20 in the process of removal. In the present invention, the snap-fit structure between the outside air introduction panel 21 and the mounting plate 22 is made difficult or non-removable by providing the retreat prevention protrusion 213 and the retreat prevention concave groove 225 in combination. Thus, the risk of damage to the outside air introduction panel assembly 20 can be reduced and prevented from being accidentally removed (ie, when removing the outside air introduction panel assembly 20 from the housing 10). It is possible to prevent the outside air introduction panel 21 or the mounting plate 22 from being accidentally removed).

Specifically, as shown in FIG. 5, the retreat prevention protrusion 213 is provided on the inner side surface of the outside air introduction panel 21, and the retreat prevention concave groove 225 is provided on the outer surface of the mounting plate 22.

Further, as shown in FIGS. 7, 8 and 11 to 16, an alignment groove 226 provided adjacent to the retreat prevention concave groove 225 is further provided on the outer surface of the mounting plate 22. The alignment groove 226 is used to guide the retreat prevention protrusion 213 so as to slide into the retreat prevention concave groove 225. In this way, the difficulty of mounting between the outside air introduction panel 21 and the mounting plate 22 can be reduced.

Since the outside air introduction panel 21 and the mounting plate 22 are slidably mounted, at the time of pre-positioning (that is, when the locking protrusion 212 is inserted into the mounting gap of the locking hole 224), the retreat prevention protrusion 213 and If there is a gap between the retreat prevention recessed grooves 225 and the alignment groove 226 is not provided, the retreat prevention protrusion 213 directly abuts on the outer surface of the mounting plate 22, so that the outside air introduction panel 21 and the mounting plate 22 It becomes difficult to install.

In the present invention, by providing the alignment groove 226, the retreat prevention protrusion 213 is inserted into the positioning protrusion at the time of preliminary positioning (that is, when the locking protrusion 212 is inserted into the mounting gap of the locking hole 224). This facilitates preliminary alignment of the outside air introduction panel 21 and the mounting plate 22, thereby reducing the difficulty of mounting between the outside air introduction panel 21 and the mounting plate 22, and then with the outside air introduction panel 21. When the mounting plate 22 moves relatively, the retreat prevention protrusion 213 slides into the retreat prevention concave groove 225 from the inside of the alignment groove 226, thereby completing the mounting between the outside air introduction panel 21 and the mounting plate 22. Can be done.

In a specific embodiment, the alignment groove 226 and / or the retreat prevention protrusion 213 can be further improved because it is easy to guide the retreat prevention protrusion 213 to slide into the retreat prevention concave groove 225 from the inside of the alignment groove 226. .. This will be explained in detail below.

Specifically, as shown in FIGS. 7, 8 and 11 to 16, the alignment groove 226 includes a guide inner wall 2261 adjacent to the retreat prevention concave groove 225, and at least a part of the guide inner wall 2261. Is arranged diagonally in the direction approaching the retreat prevention concave groove 225.
