Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an installation structure of a filter screen assembly and an air conditioner thereof. Background Art

[0002] At present, there are two installation methods for the filter screen of the wall-mounted air conditioner indoor unit.

[0003] The first one is to set the filter screen in the middle frame. The following problems exist in this installation method:

[0004] On the one hand, when cleaning the filter screen, it is necessary to first open the panel and then pull out the filter screen. It is inconvenient for users to operate, and the panel is prone to misassembly after cleaning. Frequent opening and closing of the panel can cause the hooks on the panel assembled with the middle frame to deform or even break, bringing a poor experience to users;

[0005] On the other hand, the filter screen is close to the evaporator, making it easier to get damp and breed bacteria, increasing the probability of filter screen clogging and having a greater impact on performance.

[0006] The second one is to install the filter screen outside the hanging machine. Currently, a clip matching method is generally used to connect the filter screen to the outside of the hanging machine. The following problems exist in this installation method:

[0007] On the one hand, if the clips are too tight, it is difficult to operate during production line assembly and subsequent user cleaning. If the clips are relatively loose, at least two tapes need to be pasted to fix the filter screen, resulting in an increase in the cost of a single machine and an increase in manual operation. Otherwise, the filter screen is prone to falling off during transportation;

[0008] On the other hand, a handle position needs to be designed on the filter screen to facilitate removing the filter screen for cleaning, which destroys the integrity and beauty of the overall appearance of the machine. Summary of the Utility Model

[0009] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide an installation structure of a filter screen assembly and an air conditioner thereof to solve the problems existing in the prior art of installing the filter screen outside the hanging machine and using a clip matching method to connect the filter screen to the outside of the hanging machine.

[0010] To achieve the above purpose, the utility model adopts the following technical scheme: An installation structure of a filter screen assembly for connecting a filter screen assembly to the outside of a middle frame, including a plurality of magnetic connection components, and each magnetic connection component includes:

[0011] A magnetic generation part, which is clamped in a clamping groove formed on the inner side of the filter screen assembly or the outside of the middle frame;

[0012] A magnetic receiving part, which is clamped and positioned in a clamping hole formed on the outside of the middle frame or the inner side of the filter screen assembly and magnetically adsorbs with the magnetic generation part.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The installation structure of the filter screen assembly connects the filter screen assembly to the outside of the middle frame by means of magnetic adsorption of multiple magnetic connection components. Compared with setting the filter screen assembly inside the middle frame, the filter screen assembly is farther away from the evaporator, reducing the growth of bacteria and the probability of dirt blockage. Specifically, the magnetic generation part is stably clamped in the clamping groove, and the magnetic receiving part is clamped and positioned in the clamping hole. When assembling the filter screen assembly, directly take the filter screen assembly and perform magnetic adsorption through the magnetic receiving part and the magnetic generation part, quickly installing the filter screen assembly on the outside of the middle frame, without the need to cooperate with tape to fix the filter screen assembly and without the need to additionally set a handle position on the filter screen assembly.

Detailed Embodiments

[0024] The present invention is further described in detail below through specific implementation methods:

[0025] The existing filter installation method is to install the filter on the outside of the hanging machine with a clip. This installation method has the following problems: On the one hand, if the clip is too tight, it will be difficult to operate during production line assembly and subsequent user cleaning. If the clip is loose, at least two pieces of tape will need to be pasted to fix the filter, resulting in increased cost per machine and increased labor for operation. Otherwise, the filter will easily fall off during transportation. On the other hand, a handle position must be designed on the filter to facilitate the removal of the filter for cleaning, which destroys the integrity and beauty of the overall appearance of the machine. In order to solve this problem, Figures 2 - 8 As shown, an embodiment of the present invention proposes a filter assembly installation structure for connecting the filter assembly 1 to the outside of the middle frame 2, including multiple magnetic connection components, each of which includes a magnetic generating part 3 and a magnetic receiving part 4, the magnetic generating part 3 is snapped into the snap-in groove 5 formed on the inner side of the filter assembly 1 or the outer side of the middle frame 2, and the magnetic receiving part 4 is snapped and positioned in the snap-in hole 6 formed on the outer side of the middle frame 2 or the inner side of the filter assembly 1 and is magnetically adsorbed with the magnetic generating part 3.

[0026] The filter assembly installation structure of this invention connects the filter assembly 1 to the outside of the middle frame 2 by means of magnetic adsorption through multiple magnetic connection assemblies. Compared with setting the filter assembly 1 in the middle frame 2, the filter assembly 1 is farther away from the evaporator, and the filter assembly 1 reduces bacterial growth and reduces the chance of dirt and blockage. Specifically, the magnetic generating part 3 is stably snapped into the snap groove 5, and the magnetic receiving part 4 is snapped and positioned in the snap hole 6. When assembling the rear filter assembly 1, the filter assembly 1 is directly taken and magnetically adsorbed by the magnetic receiving part 4 and the magnetic generating part 3, so that the filter assembly 1 can be quickly installed on the outside of the middle frame 2. There is no need to use tape to fix the filter assembly 1, and there is no need to set an additional buckle position on the filter assembly 1.

[0027] In this embodiment, the magnetic generating portion 3 is clamped on the inner side of the filter assembly 1 and the magnetic receiving portion 4 is clamped and positioned on the outer side of the middle frame 2 for illustration.

[0028] Specifically: the filter assembly 1 is square, and the number of magnetic connection assemblies used is two, and the magnetic generating parts 3 in the two magnetic connection assemblies are specifically arranged in the two snap-in grooves 5 on the inner side of the filter assembly 1. The two snap-in grooves 5 are distributed on the inner side of the filter assembly 1 and are located at one end of the two side edges in the width direction of the filter assembly 1. The magnetic receiving parts 4 in the two magnetic connection assemblies are arranged in the two snap-in holes 6 on the outer side of the middle frame 2. The two snap-in holes 6 are distributed on the two side edges of the outer side of the middle frame 2 that are arranged opposite to each other.

[0029] To better understand this solution, the following will further optimize structures such as the clamping groove 5, the magnetic generation part 3, and the magnetic receiving part 4.

[0030] As Figure 3 , Figure 4 and Figure 5 shown, according to another embodiment of the present invention, for the installation structure of a filter screen assembly, the clamping groove 5 is formed by surrounding a plurality of limiting ribs 51 circumferentially arranged on the inner side of the filter screen assembly 1 or the outer side of the middle frame 2, and at least one free end of the limiting rib 51 is formed with a limiting hook 52 extending in the direction of the central axis of the clamping groove 5.

[0031] In this embodiment:

[0032] The magnetic generation part 3 is a rectangular magnet block. A plurality of limiting ribs 51 surround and form the clamping groove 5 on the inner side of the filter screen assembly 1. The limiting ribs 51 have a certain elasticity. During the process of pressing the magnetic generation part 3 into the clamping groove 5, the limiting ribs 51 will deform. After the magnetic generation part 3 is assembled in the clamping groove 5, it is limited and fixed by the limiting hook 52, so that the magnetic generation part 3 is stably clamped and limited in the clamping groove 5.

[0033] In order to improve the assembly stability of the magnetic generation part 3 in the clamping groove 5 and facilitate pressing the magnetic generation part 3 into the clamping groove 5 for assembly, there are two limiting ribs 51 formed with the limiting hook 52 and arranged oppositely, and guiding inclined surfaces 53 guiding into the clamping groove 5 are formed on both limiting hooks 52.

[0034] Among them, the number of the limiting ribs 51 is four and they are arranged in pairs. One limiting rib 51 without a limiting hook 52 is the side wall of a notch opened on the inner side of the filter screen assembly 1, and the other limiting ribs 51 are all placed in the notch to reasonably assemble the magnetic generation part 3.

[0035] As Figure 3 , Figure 6 , Figure 7 and Figure 8 shown, according to another embodiment of the present invention, for the installation structure of a filter screen assembly, the magnetic receiving part 4 has an acting unit 41 cooperating with the magnetic generation part 3 and a connecting unit connected to the acting unit 41. The acting unit 41 protrudes outside one end of the clamping hole 6, and the connecting unit passes through the clamping hole 6 and is placed outside the other end of the clamping hole 6 and abuts against the middle frame 2 or the filter screen assembly 1.

[0036] In this embodiment:

[0037] The magnetic receiving part 4 is specifically a magnetic iron sheet. The acting unit 41 of the magnetic iron sheet cooperates with the magnetic generating part 3 for magnetic adsorption. The connecting unit of the magnetic iron sheet passes through the clamping hole 6 and abuts against the middle frame 2, so that the magnetic iron sheet can be stably installed on the middle frame 2 and cooperate with the magnetic generating part 3.

[0038] Wherein, the connecting unit includes two connecting ears 42 connected to the acting unit 41. The two connecting ears 42 are arranged separately on the acting unit 41 and both pass through the clamping hole 6 and abut against the middle frame 2 or the filter screen assembly 1. Specifically, both connecting ears 42 pass through the clamping hole 6 and abut against the middle frame 2 to ensure that the magnetic iron sheet can be stably installed on the middle frame 2.

[0039] Here, the acting unit 41 of the magnetic iron sheet is a horizontal iron segment. Both connecting ears 42 are in an "L" shape. The end parts of the vertical segments of the two connecting ears 42 are respectively connected to both ends of the horizontal iron segment and the two connecting ears 42 are located on the same side of the horizontal iron segment. The horizontal segments of the two connecting ears 42 are located outside the vertical segments of the two connecting ears 42. After the magnetic iron sheet is installed, specifically: the horizontal iron segment is located outside the middle frame 2 to cooperate with the magnetic generating part 3. The vertical segments of the two connecting ears 42 pass through the clamping hole 6 and the horizontal segments of the two connecting ears 42 abut against the inner side of the middle frame 2.

[0040] In order to further improve the assembly stability of the magnetic receiving part 4, a positioning and strengthening part 7 is formed in the clamping hole 6. The positioning and strengthening part 7 includes a support rib 71 that abuts against the side of the acting unit 41 facing the inside of the clamping hole 6. Among them, the positioning and strengthening part 7 is arranged in the middle of the clamping hole 6 to divide the clamping hole 6 into a left hole and a right hole. When the magnetic iron sheet is installed, one of the connecting ears 42 passes through the left hole and abuts against the inner side of the middle frame 2 on the left side wall of the left hole, and the other connecting ear 42 passes through the right hole and abuts against the inner side of the middle frame 2 on the right side wall of the right hole. At the same time, the support rib 71 abuts against the horizontal iron segment to improve the assembly stability of the magnetic receiving part 4.

[0041] Based on the above solution:

[0042] The positioning and strengthening part 7 further includes a spring piece 72 connected to one side of the support rib 71 and placed in the clamping hole 6. A limiting rib 73 is connected to the spring piece 72; after assembly, the spring piece 72 passes through the assembly hole 43 formed on the connecting unit and the limiting rib 73 abuts against the side of the connecting unit away from the support rib 71.

[0043] In this embodiment, the assembly hole 43 is formed between the vertical segment and the horizontal segment of the connecting ear 42. During the assembly process, the spring piece 72 can undergo a certain elastic deformation, so that the limiting rib 73 passes through the assembly hole 43 from the inside of the connecting ear 42 and abuts against the outside of the connecting ear 42 to further improve the assembly stability of the magnetic receiving part 4.

[0044] Such as Figure 4and Figure 6 As shown in Figure 6 , according to another embodiment of the present utility model, the installation structure of the filter screen assembly further includes a plurality of pre-positioning components. Each pre-positioning component includes a pre-positioning hook 8 and a clamping portion. The pre-positioning hook 8 is connected to the inner side of the filter screen assembly 1 or the outer side of the middle frame 2, and the clamping portion is connected to the outer side of the middle frame 2 or the inner side of the filter screen assembly 1 and is used for clamping and cooperating with the pre-positioning hook 8.

[0045] In this embodiment: there are two pre-positioning components, and the two pre-positioning hooks 8 are connected to the inner side of the filter screen assembly 1. The two pre-positioning hooks 8 are distributed on one side of the filter screen assembly 1 in the length direction, and the two pre-positioning hooks 8 are also located between the two clamping grooves 5; the two clamping portions are connected to the corresponding positions on the outer side of the middle frame 2.

[0046] After the filter screen assembly 1 is installed on the outer side of the middle frame 2, the pre-positioning hook 8 is clamped and cooperated with the corresponding clamping portion to improve the assembly stability of the filter screen assembly 1 on the middle frame 2.

[0047] such as Figure 4 and Figure 6 As shown in Figure 4 and Figure 6 , according to another embodiment of the present utility model, the installation structure of the filter screen assembly further includes a plurality of plug-in positioning components. Each plug-in positioning component includes a plug pin 9 and an insertion slot 10. The plug pin 9 is connected to the inner side of the filter screen assembly 1 or the outer side of the middle frame 2, and the insertion slot 10 is opened on the outer side of the middle frame 2 or the inner side of the filter screen assembly 1 and is used for the plug pin 9 to be inserted for positioning.

[0048] In this embodiment, there are five plug-in positioning components, and the five plug pins 9 are connected to the inner side of the filter screen assembly 1. The five plug pins 9 are distributed on the other side of the filter screen assembly 1 in the length direction, and the five insertion slots 10 are opened at the corresponding positions on the outer side of the middle frame 2.

[0049] After the filter screen assembly 1 is installed on the outer side of the middle frame 2, the plug pin 9 is inserted into the corresponding insertion slot 10 to improve the matching accuracy between the pre-positioning hook 8 and the corresponding clamping portion and between the magnetic generating portion 3 and the corresponding magnetic receiving portion 4.

[0050] When assembling the installation structure of the filter screen assembly:

[0051] Insert the plug pin 9 into the corresponding insertion slot 10, and then rotate the filter screen assembly 1 to assemble the pre-positioning hook 8 and the corresponding clamping portion in place. At the same time, the magnetic generating portion 3 and the corresponding magnetic receiving portion 4 are magnetically adsorbed to quickly complete the assembly of the filter screen assembly 1.

[0052] such as Figures 1 - 8As shown, according to another embodiment of the present utility model, the air conditioner includes a filter screen assembly 1 and a middle frame 2, and the filter screen assembly 1 is connected to the outside of the middle frame 2 through a filter screen assembly installation structure as described in any of the above embodiments.

[0053] This air conditioner uses the above-mentioned filter screen assembly installation structure to connect the filter screen assembly 1 and the middle frame 2, making the assembly between the filter screen assembly 1 and the middle frame 2 more convenient and rapid, and the structure of the middle frame 2 is simple to mold here, which is more conducive to subsequent mass production.

[0054] At the same time, the filter screen assembly adopts a magnetic adsorption method, and the installation is more stable, which not only retains the integrity of the overall appearance but also improves the user experience. Moreover, it also prevents the generation of resonance during the operation of the air conditioner due to the simple gap fluctuation of the snap-fit caused by injection molding fluctuations.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered by the scope of the claims of the present utility model.
