Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and particularly to a novel connection structure for a filter net and an air conditioner. Background Art

[0002] The filter net of an air conditioner indoor cabinet machine is mainly fixed on the inner machine housing by means of snap connection. However, the fixing method of connecting the filter net and the housing by snaps has the following defects: insufficient elasticity of the snaps will weaken the fixing effect, resulting in looseness between the filter net and the inner machine housing and causing shaking; while too much elasticity will make it difficult for users to disassemble and assemble the filter net. At present, the main setting method of the filter net connection structure is: adding a connecting rod and a tension spring on one side of the filter net, and pushing the connecting rod into a preset groove in the housing by compressing the spring to achieve the locking function. When disassembly is required, the connecting rod is pulled out of the groove by rotating a gear. Although this disassembly and assembly method has a good fixing effect, it is difficult and complicated to operate. At the same time, considering that the connecting rod is relatively long and prone to deformation, it is also likely to affect the use effect. Therefore, it is necessary to design a filter net connection structure that is convenient for disassembly and assembly and has a good installation effect. Summary of the Invention

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The principle and structure of the present invention will be described in detail below with reference to the drawings and embodiments.

[0026] The present invention proposes a novel connection structure for a filter screen. As Figure 1 shown, this novel connection structure 1 is used to fix the filter screen 3 on the housing 2.

[0027] As Figure 2 shown, the novel connection structure 1 includes a first buckle 11, a second buckle 12 and a driving device.

[0028] Wherein the first buckle 11 and the second buckle 12 are movably fixed on the filter net 3. The first buckle 11 abuts against the housing 2 to snap the filter net 3 onto the housing 2. The driving device is mainly used to drive the first buckle 11 to move away from the housing 2 so that the first buckle 11 is disengaged from the housing 2. The second buckle 12 is arranged in the moving direction of the first buckle 11 and abuts against the second buckle 12, so as to prevent the first buckle 11 from disengaging from the housing 2 and complete the installation of the filter net on the housing; move the second buckle 12 to disengage it from the first buckle so that the first buckle 11 can move away from the housing to achieve the effect of mutual abutment, thereby completing the disassembly of the filter net.

[0029] Specifically, the filter net 3 is an arc-shaped regular plate structure. The left and right edge parts of the filter net are each provided with an unlimited number of such connection structures. Each such connection structure is paired with an installation part 14 arranged at the edge of the filter net. The first buckle 11 and the second buckle 12 are both installed on the installation part 14.

[0030] As Figure 3 shown, the installation part 14 includes an opening 131. The mouth end of the opening 131 faces the housing 2. A pair of extension plates 132 are arranged on both sides of the mouth end. The first buckle 11 and the second buckle 12 are both installed on the extension plates 132. The first buckle 11 and the second buckle 12 are rotatably connected to the filter net. A first rotating shaft 133 and a second rotating shaft 134 are arranged between the two extension plates on the pair of extension plates 132. The first rotating shaft 133 and the second rotating shaft 134 are arranged in parallel.

[0031] As Figure 4 、 5 shown, the first buckle 11 is installed on the first rotating shaft 133, the second buckle 12 is installed on the second rotating shaft 134. The left end of the first buckle 11 is a first clamping end 111 that abuts against the housing. A clamping part 21 that is opposite to the opening and is clamped with the first buckle is provided on the housing 2; the right end of the first buckle 11 is a second clamping end 112 that abuts against the second buckle 12. The first clamping end 111 and the second clamping end 112 are respectively arranged on both sides of the first rotating shaft 133.

[0032] In an embodiment, the driving device can be a pair of mutually exclusive magnets, which includes a first magnet arranged on the clamping part 21 of the housing 2 and a second magnet arranged on the first clamping end 111. The first magnet and the second magnet have opposite magnetic poles, thereby driving the first buckle 11 to rotate around the first rotating shaft 133, and the first clamping end 111 moves away from the housing 2 to cancel the abutting effect on the filter net and the housing.

[0033] As Figure 6As shown, the driving device can also be an elastic telescopic member, such as a torsion spring or a shrapnel; in another embodiment, the elastic telescopic member is a torsion spring 13. A stopper 135 is provided between a pair of extension plates 132. The stopper 135 is located below the first buckle 11. The torsion spring is sleeved on the first rotating shaft 133. The two elastic arms of the torsion spring are located on the right side of the first rotating shaft 133, that is, on the side of the second clamping end 112. One of the elastic arms abuts against the first buckle, and the other elastic arm abuts against the stopper, so that the torsion spring can abut against the second clamping end 112 and rotate. At this time, the first clamping end 111 moves away from the housing 2 to orient the buckling effect on the filter net and the housing.

[0034] The second buckle 12 includes a main body 121. The main body 121 is a pressing part for the operator to press. The main body 121 is located on one side of the second rotating shaft 134. Pressing the main body 121 causes the second buckle to rotate around the second rotating shaft 134. The left end of the main body 121 is the third clamping end 122 that abuts against the first buckle. The contact part (force application point) between the third clamping end 122 and the first buckle 11 is located on the side of the main body 121 of the second rotating shaft 134 or passes through the rotating shaft under force. In this way, the moment of the third clamping end 122 relative to the second rotating shaft 134 is 0, so that the second buckle can abut against the first buckle, and the second buckle will not rotate synchronously under force when the first buckle rotates, avoiding the situation where the second buckle 12 cannot play a role in buckling the first buckle 11 and ensuring the buckling effect.

[0035] Further, the right end of the main body 121 is the fourth clamping end 123. The fourth clamping end 123 is far from the second rotating shaft 134. The fourth clamping end 123 abuts against the inner side of the filter net. The third clamping end 122 is affected by the acting force of the first buckle, and the third clamping end 122 is located on the side of the main body 121 of the second rotating shaft 134. Therefore, when the second buckle 12 is pushed by the first buckle, the second buckle will not rotate out of the filter net. It always abuts against the first buckle to ensure the clamping effect between the first buckle and the housing, and ensure the good assembly between the filter net and the housing.

[0036] Further, to keep the second buckle stable, a magnet or an elastic structure that attracts each other can also be provided between the fourth clamping end 123 and the housing so that the second buckle can be kept in contact with the housing to ensure the buckling effect.

[0037] Further, the width of the main body 121 should be designed to be approximately the width of a finger, which not only avoids affecting pressing, but also avoids affecting the air supply area due to the too large area of the buckle; at the same time, the appearance surface of the buckle structure should fit with the appearance of the filter net to avoid external interference with the buckle and ensure beauty.

[0038] Preferably, the buckle and the rotating shaft in the present invention can be made of metal parts or injection molded parts. However, due to their small size, they have relatively high requirements for strength and stability. Ordinary injection molded parts have poor strength and stability, so metal parts are preferred.

[0039] The connection structure makes the disassembly and assembly between the filter net and the housing simple and the installation stable. When the filter net needs to be disassembled, press the second buckle 12. Under the action of external force, the second buckle 12 moves towards the inner side of the housing, and the second buckle loses the binding effect on the second clamping end 112 of the first buckle 11. The first buckle 11 flips under the action of the driving device, and the first clamping end 111 of the first buckle 11 is separated from the housing to disassemble the filter net; when installing the filter net, buckle the filter net. First, press down the first buckle 11, and then push the second buckle 12 to abut against the first buckle 11, and the installation is completed. The disassembly and assembly of the filter net can be completed by pressing the second buckle 12. At the same time, the second buckle 12 provides a constraint on the first buckle, and they will not automatically separate without external force applied. The first buckle will be tightly clamped with the housing, thus ensuring the assembly effect between the filter net and the housing.

[0040] The present invention also proposes an air conditioner, which includes the novel connection structure of the filter net proposed by the present invention.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
