Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a base structure and a wall-mounted air conditioner. BACKGROUND

[0002] The existing air conditioner with fresh air function includes an air conditioner base and a fresh air base. The fresh air base is used for installing a fresh air component for realizing the fresh air function, and the air conditioner base is used for installing a component for realizing the air conditioning function. However, the existing fresh air base is not convenient to install, and the connection stability between the fresh air base and the air conditioner base is poor. SUMMARY

[0003] The problem solved by the present application is how to conveniently and stably install the fresh air base.

[0004] To solve the above problems, in a first aspect, the present application provides a base structure applied to a wall-mounted air conditioner, including an air conditioner base and a fresh air base. The air conditioner base is used for installing a heat exchange component, and the fresh air base is used for installing a fresh air component. One of the air conditioner base and the fresh air base is provided with an embedded part, and the other is provided with a sliding groove. The embedded part and the sliding groove are in sliding cooperation. The fresh air base has an assembly position in the extension direction of the sliding groove. The fresh air base is connected with the air conditioner base through a limiting structure. The limiting structure is used for keeping the fresh air base at the assembly position.

[0005] In the embodiments of the present application, the structure of the sliding groove and the embedded part is added between the air conditioner base and the fresh air base. When installing the fresh air base, the installer can embed the embedded part into the sliding groove, then slide the fresh air base to the assembly position, and then keep the fresh air base at the assembly position through the limiting structure. The cooperation of the sliding groove and the embedded part facilitates the installer to find the assembly position of the fresh air base and facilitates the positioning of the fresh air base, so that the installation of the fresh air base is easier. In addition, through the sliding groove and the embedded part, the position of the fresh air base can be limited to some extent, so that the connection stability between the fresh air base and the air conditioner base is improved.

[0006] In an optional embodiment, the limiting structure includes a fixed plate. The fixed plate is arranged at one end of the sliding groove to block the embedded part from sliding along the sliding groove, and the other end of the sliding groove is open. The fixed plate is provided with a first matching hole, and one end of the embedded part is provided with a first mounting hole. When the fresh air base is at the assembly position, the end of the embedded part provided with the first mounting hole abuts against the fixed plate, and the first matching hole corresponds to the first mounting hole and is connected through a fastener. During installation, the embedded part slides from the open end of the sliding groove to the end provided with the fixed plate. When the fresh air base is slid to the assembly position, the end of the embedded part provided with the first mounting hole abuts against the fixed plate. At this time, the fastener can be used to connect the fresh air base and the air conditioner base. During installation, the positioning of the fresh air base is easy, so that the installation difficulty can be reduced and the installation efficiency can be improved.

[0007] In an optional embodiment, the sliding groove is arranged on the fresh air base, and the embedding part is arranged on the air conditioner base. When installing the fresh air base, the fresh air base is usually held by hand and installed on the air conditioner base. Therefore, arranging the sliding groove on the fresh air base can make the fresh air base have a lighter weight, and facilitate hand-held installation.

[0008] In an optional embodiment, the embedding part extends in the vertical direction, and the first mounting hole is arranged at the upper end of the embedding part. In this embodiment, the fresh air base can be slid along the length direction of the embedding part from top to bottom to the assembly position during installation. When reaching the assembly position, the fixed plate at the upper end of the sliding groove can abut against the upper end of the embedding part, and the first mounting hole is opposite to the first matching hole. In this embodiment, when the sliding direction of the fresh air base is the direction of gravity, the fresh air base can be easily slid to the assembly position. After the fresh air base reaches the assembly position, the embedding part can support the fixed plate, and excessive external force is not needed to hold up the fresh air base when tightening the fastener, so that the entire installation operation is more labor-saving.

[0009] In an optional embodiment, the limiting structure further comprises a second mounting hole arranged on the air conditioner base and a second matching hole arranged on the fresh air base. The first matching hole and the second matching hole are respectively close to two ends of the fresh air base in the vertical direction. When the fresh air base is in the assembly position, the second matching hole corresponds to the second mounting hole and is connected by the fastener. In this embodiment, the first matching hole and the second matching hole are respectively arranged at the two end positions of the fresh air base, which can fix the fresh air base at the upper and lower positions, so that the stability of the fresh air base is better.

[0010] In an optional embodiment, the fresh air base has a back side facing the wall surface, the second matching hole is a through hole, one end of the second matching hole is opposite to the second mounting hole, and the other end is exposed on the back side of the fresh air base. In this embodiment, one end of the second matching hole faces the air conditioner base, and the other end is exposed on the back side of the fresh air base. In the use state, the two ends of the second matching hole are covered by the wall surface and the air conditioner base respectively, which is conducive to hiding the fastener and improving the user experience.

[0011] In an optional embodiment, the limiting structure further comprises a clamping groove and a limiting plate. The clamping groove is arranged on one of the fresh air base and the air conditioner base, and the limiting plate is arranged on the other one of the fresh air base and the air conditioner base. When the fresh air base is slid to the assembly position, the limiting plate is inserted into the clamping groove to limit the fresh air base from moving away from the air conditioner base in the depth direction of the sliding groove. In this embodiment, the limiting plate and the clamping groove can be inserted and matched when the fresh air base is slid to the assembly position. This insertion and matching mode can prevent the embedding part from moving out of the opening of the sliding groove, that is, prevent the fresh air base from moving away from the air conditioner base in the depth direction of the sliding groove. By arranging the limiting plate and the clamping groove, the fresh air base can be limited in the depth direction of the sliding groove, and the stability of the fresh air base in this direction is improved.

[0012] In an optional embodiment, the limiting structure comprises two clamping grooves and two limiting plates, and the two limiting plates are respectively matched with the two clamping grooves at both ends of the sliding groove. In this embodiment, the upper and lower ends of the sliding groove are fixed by the clamping grooves and the limiting plates, respectively, and the stability is better.

[0013] In an optional embodiment, the limiting structure further comprises a buckle provided on one of the fresh air base and the air conditioner base, and a clamping hole provided on the other one of the fresh air base and the air conditioner base; when the fresh air base slides to the assembly position, the buckle is matched with the clamping hole. In this embodiment, the connection strength between the fresh air base and the air conditioner base is increased by the matching of the buckle and the clamping hole, and meanwhile, the matching mode of the buckle and the clamping hole is also convenient for assembly and disassembly.

[0014] In an optional embodiment, the buckle is provided at the bottom of the sliding groove, the embedded part has an end face opposite to the bottom of the sliding groove, and the clamping hole is provided on the end face of the embedded part. In this embodiment, the buckle is provided at the bottom of the sliding groove, and the clamping hole is provided on the end face of the embedded part, so that when the fresh air base slides to the assembly position, the buckle and the clamping hole can be shielded by the fresh air base, which realizes the protection of the buckle and the clamping hole and makes the appearance more beautiful.

[0015] In an optional embodiment, the fresh air base is provided at one end of the air conditioner base in the transverse direction.

[0016] In a second aspect, the application provides a wall-mounted air conditioner comprising the base structure of any one of the foregoing embodiments. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0029] Currently, wall-mounted air conditioners with fresh air functions have emerged, comprising an air conditioner base and a fresh air base. The fresh air base is used to install the fresh air component that enables the fresh air function, while the air conditioner base is used to install the air conditioning component. However, existing fresh air bases are primarily connected using screws and other fasteners. During installation, the fresh air base needs to be held in the mounting position, aligned with the holes, and then tightened using fasteners. This base structure is not convenient for installation, and the connection stability between the fresh air base and the air conditioner base is relatively poor.

[0030] To address the issues of inconvenient installation and poor stability of existing fresh air unit bases, this application provides a base structure in which the fresh air unit base and the air conditioner base achieve a sliding fit through a sliding groove and an insert, and are further stabilized by a limiting structure. This base structure offers the advantages of easy installation and good stability for the fresh air unit base. Furthermore, this application also provides a wall-mounted air conditioner incorporating the aforementioned base structure.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the base structure 010 in one embodiment of this application; Figure 2 This is a schematic diagram of a base structure 010 equipped with a fresh air component 020 in one embodiment of this application. Figure 1and Figure 2 As shown, the base structure 010 provided in this embodiment includes an air conditioner base 100 and a fresh air base 200. The air conditioner base 100 is used to install structures such as a heat exchange component (not shown in the figure), an air outlet component (not shown in the figure), and a fan (not shown in the figure), while the fresh air base 200 is used to install a fresh air component 020. It should be understood that the fresh air component 020 is used to introduce fresh outdoor air into the room, while the heat exchange component, air outlet component, fan, etc. on the air conditioner base 100 are used to regulate the indoor ambient temperature.

[0033] Figure 3 This is a schematic diagram of an air conditioner base 100 from a first-view perspective in one embodiment of this application. In this embodiment, one of the air conditioner base 100 and the fresh air base 200 is provided with an insert portion 110, and the other is provided with a sliding groove 201. The insert portion 110 and the sliding groove 201 are slidably engaged. The fresh air base 200 has an assembly position in the extending direction of the sliding groove 201. The fresh air base 200 and the air conditioner base 100 are connected by a limiting structure, which is used to hold the fresh air base 200 in the assembly position. Figure 3 As shown, specifically in this embodiment, the embedded part 110 is disposed on the air conditioner base 100, and the sliding groove 201 is disposed on the fresh air base 200. One end of the air conditioner base 100 in the horizontal direction is used to connect to the fresh air base 200; in this embodiment, specifically, the left end is connected to the fresh air base 200. The left end of the air conditioner base 100 has the embedded part 110, which extends vertically (referring to the vertical direction of the air conditioner in normal use). Therefore, when the fresh air base 200 is installed, the cooperation between the sliding groove 201 and the embedded part 110 allows the fresh air base 200 to be slid vertically to the assembly position. It can be understood that the cooperation between the sliding groove 201 and the embedded part 110 limits the position of the fresh air base 200 in the front-back direction.

[0034] It should be understood that when installing the fresh air base 200, it is usually held in hand and installed onto the air conditioner base 100. Therefore, setting the slide groove 201 on the fresh air base 200 can make the fresh air base 200 lighter and easier to install by hand. In other optional embodiments of this application, the positions of the embedding part 110 and the slide groove 201 can also be interchanged, that is, the slide groove 201 is set on the air conditioner base 100 and the embedding part 110 is set on the fresh air base 200.

[0035] Figure 4 for Figure 3 A schematic diagram of a local IV region. (See diagram below.) Figure 4As shown, the limiting structure includes a first mounting hole 111 provided at the embedding portion 110, and the first mounting hole 111 is provided at the upper end of the embedding portion 110. In the embodiment, the opening of the first mounting hole 111 is upward, which can be directly upward or inclined upward, and the first mounting hole 111 is used to connect the fresh air base 200 by a fastener such as a screw.

[0036] Figure 5 For Figure 3 a schematic view of the middle part V. As Figure 4 and Figure 5 shown, the limiting structure further includes a clamping groove and a limiting plate, and in the embodiment, the limiting plate is provided at the air conditioner base 100, and the clamping groove is provided at the fresh air base 200; of course, in alternative embodiments, the positions of the limiting plate and the clamping groove can be transposed. In the embodiment, the limiting plate includes a first limiting plate 120 and a second limiting plate 130, and the first limiting plate 120 and the second limiting plate 130 are spaced apart in the height direction; correspondingly, two clamping grooves are also provided on the fresh air base 200. In the embodiment, the first limiting plate 120 and the second limiting plate 130 are vertically erected, and thus can be inserted into the clamping grooves of the fresh air base 200 from bottom to top. After the limiting plate is inserted into the clamping groove, the fresh air base 200 can be limited from moving away from the air conditioner base 100 in the lateral direction, thereby achieving the limiting of the fresh air base 200 in the horizontal direction.

[0037] Figure 6 is a schematic view of the fresh air base 200 in a first perspective view in an embodiment of the present application; Figure 7 is a schematic view of the fresh air base 200 in a second perspective view in an embodiment of the present application. As Figure 6 and Figure 7 shown, the fresh air base 200 is provided with a sliding groove 201 on one side for connecting the air conditioner base 100, and in order to match the embedding portion 110, the sliding groove 201 also extends along the vertical direction. Of course, in alternative embodiments, the embedding portion 110 can also not extend along the vertical direction, but can extend horizontally or obliquely, and the extension direction of the sliding groove 201 should match it. In the embodiment, the limiting structure includes a fixed plate 210 provided at one end of the sliding groove 201 to block the embedding portion 110 from sliding along the sliding groove 201, and the other end of the sliding groove 201 is open. In the embodiment, the fixed plate 210 is provided at the upper end of the sliding groove 201. The fixed plate 210 is provided with a first matching hole 211, and when the fresh air base 200 is in the assembled position, the end of the embedding portion 110 provided with the first mounting hole 111 abuts against the fixed plate 210, the first matching hole 211 corresponds to the first mounting hole 111, and is connected by a fastener such as a screw.

[0038] Furthermore, in this embodiment, the limiting structure also includes a first slot 220 and a second slot 230 on the fresh air base 200. The first slot 220 and the second slot 230 are respectively used to insert and cooperate with the first limiting plate 120 and the second limiting plate 130 on the air conditioner base 100. Since the first limiting plate 120 and the second limiting plate 130 are vertically arranged, the openings of the first slot 220 and the second slot 230 must face downwards to achieve insertion and cooperation. It can be understood that the first slot 220 and the second slot 230 also limit the vertical position of the fresh air base 200 to prevent the fresh air base 200 from moving further downwards. In other words, the fresh air base 200 can be regarded as being hung on the first limiting plate 120 and the second limiting plate 130 of the air conditioner base 100 through the first slot 220 and the second slot 230.

[0039] In this embodiment, the first slot 220 is disposed at the upper end of the slide groove 201, and the second slot 230 is disposed at the lower end of the slide groove 201. The positions of the first slot 220 and the second slot 230 should correspond to the positions of the first limiting plate 120 and the second limiting plate 130. When the fresh air base 200 slides from top to bottom to the assembly position, the limiting plate is inserted into the slot to restrict the fresh air base 200 from moving away from the air conditioner base 100 along the depth direction of the slide groove 201 (i.e., the horizontal direction in the use state). In this embodiment, the limiting plate and the slot can achieve a plug-in engagement when the fresh air base 200 slides to the assembly position. This plug-in engagement method can prevent the embedded part 110 from moving out of the opening of the slide groove 201, that is, prevent the fresh air base 200 from moving away from the air conditioner base 100 along the depth direction of the slide groove 201. By setting the limiting plate and the slot, the fresh air base 200 can be limited in the depth direction of the slide groove 201, thereby improving the stability of the fresh air base 200 in this direction.

[0040] Figure 8 This is a schematic diagram of an air conditioner base 100 from a second perspective in one embodiment of this application. Figures 6 to 8 As shown, in this embodiment, the limiting structure further includes a second mounting hole 112 disposed on the air conditioner base 100 and a second mating hole 250 disposed on the fresh air base 200. When the fresh air base 200 is in the assembled position, the second mating hole 250 corresponds to the second mounting hole 112 and can be connected by fasteners. In this embodiment, the first mating hole 211 and the second mating hole 250 are respectively located near the two ends of the fresh air base 200 in the vertical direction. Specifically, the second mating hole 250 is disposed on the opposite side of the fresh air base 200 from the slide groove 201. The first mating hole 211 and the second mating hole 250 are respectively disposed at the two ends of the fresh air base 200, which can fix the fresh air base 200 at both the upper and lower positions, making the fresh air base 200 more stable.

[0041] In the embodiment, the fresh air base 200 has a back side facing the wall surface, the second matching hole 250 is a through hole, one end of the second matching hole 250 is opposite to the second mounting hole 112, and the other end is exposed on the back side of the fresh air base 200. Since one end of the second matching hole 250 faces the air conditioner base 100, and the other end is exposed on the back side of the fresh air base 200, in the use state, the two ends of the second matching hole 250 are covered by the wall surface and the air conditioner base 100 respectively, which is beneficial to conceal the fastener and improve the user experience.

[0042] Further, in the embodiment, the limiting structure further includes a buckle 240 arranged on the fresh air base 200 and a clamping hole 113 arranged on the air conditioner base 100; when the fresh air base 200 slides to the assembly position, the buckle 240 cooperates with the clamping hole 113. In the embodiment, through the cooperation of the buckle 240 and the clamping hole 113, the connection strength between the fresh air base 200 and the air conditioner base 100 is increased, and at the same time, the cooperation mode of the buckle 240 and the clamping hole 113 is also convenient for assembly and disassembly. In the embodiment, the buckle 240 is arranged on the bottom of the sliding groove 201, the embedded part 110 has an end face opposite to the bottom of the sliding groove 201, and the clamping hole 113 is arranged on the end face of the embedded part 110. In the embodiment, arranging the buckle 240 on the bottom of the sliding groove 201 and arranging the clamping hole 113 on the end face of the embedded part 110 makes the buckle 240 and the clamping hole 113 be shielded by the fresh air base 200 when the fresh air base 200 slides to the assembly position, so that the buckle 240 and the clamping hole 113 are protected, and the appearance is also more beautiful. In the embodiment, the buckle 240 is hook-shaped, which can extend into the clamping hole 113 and be hooked on the edge of the clamping hole 113. It should be understood that in alternative embodiments, the positions of the buckle 240 and the clamping hole 113 can be transposed, that is, the buckle 240 is arranged on the air conditioner base 100, and the clamping hole 113 is arranged on the fresh air base 200.

[0043] Figure 9 For Figure 1 Enlarged view of partial IX; Figure 10 For Figure 1 Enlarged view of partial X; Figure 11 It is a schematic view of the buckle 240 in the cooperation state in an embodiment of the application. Figures 9 to 11 The cooperation schematic view of each part when the fresh air base 200 is in the assembly position is shown. During installation, the embedded part 110 of the air conditioner base 100 slides from the open end of the sliding groove 201 to the end provided with the fixed plate 210, in other words, the fresh air base 200 slides downward relative to the air conditioner base 100. When the fresh air base 200 slides to the assembly position, the end of the embedded part 110 provided with the first mounting hole 111 just abuts against the fixed plate 210, as shown in FIG. 6. Figure 9Meanwhile, the first limiting plate 120 is inserted into the first clamping groove 220, and the second limiting plate 130 is inserted into the second clamping groove 230, as shown in Figure 10 Meanwhile, the buckle 240 is inserted into the clamping hole 113, as shown in Figure 11 In this embodiment, after the fresh air base 200 is slid to the assembly position, the fresh air base 200 can be kept stable even without installing fasteners such as screws at the mounting holes and the matching holes. The fresh air base 200 is supported by the embedding part 110, the first limiting plate 120, the second limiting plate 130, and the clamping hole 113 in the vertical direction, the embedding part 110 limits the sliding groove 201 in the front-back direction, and the first limiting plate 120 and the second limiting plate 130 limit the first clamping groove 220 and the second clamping groove 230 in the horizontal direction. Therefore, in some optional embodiments, even without the fasteners, the first matching hole 211, the first mounting hole 111, the second matching hole 250, and the second mounting hole 112, the fresh air base 200 can be kept stable by the existing limiting structure. In this embodiment, by installing the fasteners at the mounting holes and the matching holes, the stability of the fresh air base 200 can be further improved. Moreover, when installing the fasteners, the fresh air base 200 can be kept stable at the assembly position under the support of the existing limiting structure without holding the fresh air base 200 by hand. Therefore, in the base structure 010 of the embodiment, the sliding groove 201, the embedding part 110, and the related limiting structure can make the installation operation simple and efficient while ensuring the stability of the fresh air base 200.

[0044] The base structure 010 provided by the embodiment of the present application can be applied to a wall-mounted air conditioner (not shown in the figure). In addition to the base structure 010 and the fresh air assembly 020, the wall-mounted air conditioner also includes necessary assemblies such as a heat exchange assembly, an air outlet assembly, and a fan for realizing the air conditioning function, which will not be introduced here.

[0045] In summary, in the base structure 010 of the embodiment of the present application, the structure of the sliding groove 201 and the embedding part 110 added between the air conditioner base 100 and the fresh air base 200 makes it easier for the installer to find the assembly position of the fresh air base 200 and position the fresh air base 200, so that the installation of the fresh air base 200 is easier. In addition, the sliding groove 201 and the embedding part 110 can limit the position of the fresh air base 200, so that the connection stability between the fresh air base 200 and the air conditioner base 100 is improved.

[0046] Although the present application has been disclosed with reference to the above examples, it is not intended to limit the present application. Any person skilled in the art, without departing from the spirit and scope of the present application, can make various changes and modifications, and the scope of protection of the present application should be limited by the scope defined in the claims.
