Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to a detachable fresh air inlet cover plate installation structure and an air conditioner. Background Art

[0002] In most cabinet air conditioners with fresh air function on the market, the connection point structure of the fresh air inlet cover and the rear panel is integrated (such as Figure 1 As shown). If the user needs to enable the fresh air function, the air inlet duct needs to be drilled, and the cover needs to be knocked or cut to make it fall off so that fresh air can be introduced. The above solution has three problems:

[0003] 1. Appearance: Hammering the holes will cause burrs and flash around the holes, affecting the appearance.

[0004] 2. Safety: Burrs and flash increase the risk of scratches when disassembling and assembling the air inlet duct.

[0005] 3. Function: It cannot be reused. If the user does not need the fresh air function later, a hole will be left after removing the air inlet pipe. The cover cannot be installed again, and dust is easily accumulated over a long period of time, which may allow rodents to enter and damage the internal structure.

[0006] These issues will affect the user experience. Summary of the invention

[0007] In order to solve the above problems, the first purpose of the utility model is to provide a detachable fresh air inlet cover installation structure, in which a cover can be detachably arranged on the fresh air inlet to avoid damage to the appearance caused by burrs and flash formed by opening holes or cutting and safety problems during assembly. In addition, the assembly and disassembly of the cover is also very convenient; the second purpose of the utility model is to provide an air conditioner.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0009] A detachable fresh air inlet cover installation structure comprises a rear panel, and is characterized in that: a fresh air inlet is opened at the lower part of the rear panel, and a cover is detachably provided on the fresh air inlet; the cover is detachably arranged on the fresh air inlet by at least one snap connection; a slot is constructed at the upper end of the fresh air inlet, and an elastic snap is provided at the upper end of the cover to be snap-connected with the slot; a locking rib is provided on both sides of the elastic snap on the inner side of the cover, and assembly stops are formed on both sides of the slot to abut and cooperate with the locking rib.

[0010] In the above technical scheme, the parts of the fresh air inlet module are divided into a rear panel and a fresh air inlet cover. The rear panel is provided with a fresh air inlet. When the fresh air function is enabled, the air inlet cover needs to be removed and the air inlet duct assembly needs to be connected. When the fresh air function is not needed, the cover is used to prevent dust and other foreign objects from entering. This solves the inconvenience of opening a fresh air inlet on the existing integrated rear panel, as well as the problem of damage to the panel surface and safety hazards after the hole is opened.

[0011] The cover plate and the fresh air inlet on the rear panel are detachably installed by means of a snap connection, and the two can also be connected by an effective detachable method such as plug-in. In addition, the cover plate in this case is adapted to the fresh air inlet, and the rear surface is flat and tight after installation. If the cover plate protrudes from the back of the rear panel, it will affect the appearance and occupy space.

[0012] The cover plate is connected to the fresh air inlet through a buckle. The cooperation between the buckle slot and the elastic buckle can effectively prevent the upper end of the cover plate from being disengaged from the buckle slot after installation. It should be noted here that the buckle handle of the elastic buckle is on the outside, which is convenient for users to remove the cover plate. The cooperation between the stop rib and the assembly stop is to prevent radial looseness between the cover plate and the fresh air inlet after the buckle connection, and play a limiting role.

[0013] Preferably, a buckle is provided on the inner side of the cover plate extending downward, and a slot is provided on the inner side of the rear panel on the fresh air inlet to match the buckle. In this technical solution, in order to further maintain the assembly stability of the cover plate and the fresh air inlet, the cover plate and the lower part of the fresh air inlet are matched by plugging the buckle into the slot, and the slot is arranged on the inner side of the rear panel, so as to avoid the exposed part of the match affecting the appearance, make the match tighter, better prevent mosquitoes from entering, and improve the overall appearance.

[0014] Preferably, a plurality of fixing plates are provided on the inner side of the cover plate, and the lower end of the fixing plates is fixedly connected to the plug buckle. In this technical solution, the provision of the plurality of fixing plates improves the structural strength of the plug buckle.

[0015] Preferably, the outer edge of the fresh air inlet is constructed with a step, the outer edge of the cover plate corresponds to the step, and a plurality of first reinforcing ribs are circumferentially arranged on the step to abut against the outer edge of the cover plate. In this technical solution, the first reinforcing ribs improve the structural strength of the step and prevent direct contact between the cover plate and the step, thereby reducing the contact area and effectively preventing abnormal noise.

[0016] Preferably, a plurality of second reinforcing ribs are provided on the inner side of the cover plate, and the second reinforcing ribs are distributed circumferentially and radially. In this technical solution, the provision of the second reinforcing ribs greatly improves the structural strength of the cover plate, and a reinforcing ring wall is formed between the radially distributed second reinforcing ribs and at least one circle of circumferentially distributed second reinforcing ribs, further improving the structural connection between the two second reinforcing ribs. In addition, the ribs extending from both sides of the buckle and the locking ribs are fixedly connected to the circumferentially distributed second reinforcing ribs, further improving the structural strength.

[0017] Preferably, an electrical appliance cover is detachably provided on the lower part of the rear panel above the fresh air inlet, and a placement rack is provided on the inner side of the rear panel near the electrical appliance cover, and a snap-in slot cooperating with the plug buckle is provided at the bottom of the placement rack. In this technical solution, in order to prevent the user from activating the fresh air, the removed cover has no fixed placement point and is easily lost over time. A simple placement rack is designed on the inner side of the rear panel near the electrical appliance cover, and a snap-in slot is provided at the bottom, and the plug buckle can be placed downward and stuck in the snap-in slot. The placement rack is located on the inner side of the rear panel, maintaining the aesthetic appearance. It is easy to take and place, and the user can take and place the appliance by removing the electrical appliance cover and inserting the plug buckle into the snap-in slot, and there is a large space for taking and does not hurt the hand.

Embodiment 1:

[0036] like Figures 2 to 12 A detachable fresh air inlet cover plate installation structure shown includes a rear panel 1, a fresh air inlet 2 is opened at the lower part of the rear panel 1, and a cover plate 3 is detachably provided on the fresh air inlet 2.

[0037] In the above technical scheme, the parts of the fresh air inlet module are divided into a rear panel and a fresh air inlet cover. The rear panel is provided with a fresh air inlet. When the fresh air function is enabled, the air inlet cover needs to be removed and the air inlet duct assembly needs to be connected. When the fresh air function is not needed, the cover is used to prevent dust and other foreign objects from entering. This solves the inconvenience of opening a fresh air inlet on the existing integrated rear panel, as well as the problem of damage to the panel surface and safety hazards after the hole is opened.

[0038] Furthermore, the cover plate 3 is detachably mounted on the fresh air inlet 2 by at least one snap connection. In this technical solution, the cover plate and the fresh air inlet on the rear panel are detachably mounted by snap connection, and the two can also be connected by effective detachable means such as plug-in. In addition, the cover plate in this case is adapted to the fresh air inlet, and the rear surface is flat and tight after installation. If the cover plate protrudes from the back of the rear panel, it will affect the appearance and occupy space.

[0039] Furthermore, a slot 4 is constructed at the upper end of the fresh air inlet 2, and an elastic clip 5 is provided at the upper end of the cover plate 3 to be snap-connected with the slot 4. In this technical solution, the cover plate is connected to the fresh air inlet through a snap, and the cooperation between the slot and the elastic clip can effectively prevent the upper end of the cover plate from being disengaged from the slot after installation. It should be noted here that the buckle of the elastic clip is on the outside, which is convenient for users to remove the cover plate.

[0040] Furthermore, the inner side of the cover plate 3 is provided with a locking rib 6 on both sides of the elastic buckle 5, and the two sides of the clamping groove 4 are formed with an assembly stopper 7 to abut against the locking rib 6. In this technical solution, the locking rib and the assembly stopper cooperate to prevent radial looseness between the cover plate and the fresh air inlet after the buckle is connected, and play a limiting role.

[0041] Furthermore, a buckle 8 is provided on the inner side of the cover plate 3 extending downward, and a slot 9 is provided on the inner side of the rear panel 1 on the fresh air inlet 2 to cooperate with the buckle. In this technical solution, in order to further maintain the assembly stability of the cover plate and the fresh air inlet, the cover plate and the lower part of the fresh air inlet are matched by plugging the buckle into the slot, and the slot is arranged on the inner side of the rear panel, so as to avoid the exposed part of the match affecting the appearance, make the match more tightly, better prevent mosquitoes from entering, and improve the overall appearance.

[0042] Furthermore, a plurality of fixing sheets 10 are provided on the inner side of the cover plate 3, and the lower end of the fixing sheet 10 is fixedly connected to the plug buckle 8. In this technical solution, the provision of the plurality of fixing sheets improves the structural strength of the plug buckle.

[0043] Furthermore, a step 11 is constructed on the outer edge of the fresh air inlet 2, and the outer edge of the cover plate 3 corresponds to the step 11. A plurality of first reinforcing ribs 12 are circumferentially arranged on the step 11 to abut against the outer edge of the cover plate 3. In this technical solution, the first reinforcing ribs improve the structural strength of the step and prevent direct contact between the cover plate and the step, thereby reducing the contact area and effectively preventing abnormal noise.

[0044] Furthermore, a plurality of second reinforcing ribs 13 are provided on the inner side of the cover plate 3, and the second reinforcing ribs 13 are distributed circumferentially and radially. In this technical solution, the provision of the second reinforcing ribs greatly improves the structural strength of the cover plate, and a reinforcing ring wall 100 is formed between the radially distributed second reinforcing ribs and at least one circle of circumferentially distributed second reinforcing ribs, further improving the structural connection between the two second reinforcing ribs. In addition, the ribs 101 extending from both sides of the buckle and the locking ribs are fixedly connected to the circumferentially distributed second reinforcing ribs, further improving the structural strength.

[0045] Furthermore, the lower part of the rear panel 1 is detachably provided with an electrical cover 15 above the fresh air inlet 2, and a placement rack 14 is provided on the inner side of the rear panel 1 near the electrical cover 15, and a snap-in slot 16 cooperating with the plug buckle 8 is provided at the bottom of the placement rack 14. In this technical solution, in order to prevent the user from activating the fresh air, the removed cover has no fixed placement point and is easy to be lost over time. A simple placement rack is designed on the inner side of the rear panel near the electrical cover, and a snap-in slot is provided at the bottom, and the plug buckle can be placed downward and stuck in the snap-in slot. The placement rack is located on the inner side of the rear panel, maintaining the aesthetic appearance. It is easy to take and place, and the user can remove the electrical cover and insert the plug buckle into the snap-in slot to place it, and there is a large space for taking and it will not hurt the hand. Embodiment 2:

[0046] An air conditioner includes a detachable fresh air inlet cover plate mounting structure in the first embodiment.

[0047] In this specific embodiment, in view of the inconvenience of opening a fresh air inlet on the integrated rear panel of the existing air conditioner, the damage to the panel surface after the hole is opened, the non-reusability and the potential safety hazards, the above solution opens a fresh air inlet on the rear panel and detachably sets a cover plate on the fresh air inlet, thereby achieving the following effects:

[0048] ① Avoid burrs and flash caused by opening holes or cutting, which may damage the appearance and cause safety problems during assembly.

[0049] ②Simple structure, easy to disassemble and install. (Users can enable or disable the fresh air function at any time, and when fresh air is not needed, the cover plate can prevent insects, dust and splashing water.)

[0050] ③It is flexible, versatile and universal, and is suitable for cabinet products with fresh air.

[0051] ④The cover frame does not occupy external space and does not affect the appearance, preventing parts from being away from the machine and preventing them from being lost.

[0052] Specifically, the design of the slot and stop assembly avoids the use of screws for positioning, protects the flatness of the appearance and makes the assembly tighter. The reinforcing ribs on the upper circle of the step and the cover plate increase their own strength, reduce the contact area between the cover plate and the mating surface, and avoid abnormal noise. The assembly is completed using elastic buckles, and the buckle handles on the outside effectively prevent the problem of too tight fit and difficult to remove. Finally, the design of the cover plate rack avoids the problem of having nowhere to put the cover plate after it is removed and it is easy to lose, which improves the user experience to a certain extent.

[0053] When using, first insert the buckle into the slot to limit its left and right movement, then align the elastic buckle and buckle it in. The left and right ribs of the buckle limit the rotation to complete the assembly. After the fresh air cover is installed in place, the buckle handle of the elastic buckle faces outwards, which is convenient for disassembly and installation.

[0054] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0055] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
