For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Combine the following Figures 1 to 3 The present invention describes a water leakage prevention device for an air conditioner and an air conditioner.

[0040] See also Figures 1 to 3 The first aspect of the present application provides a water leakage prevention device for an air conditioner. The air conditioner 1 includes an indoor unit housing 11, an air duct 12, a water receiving tray 13 and a connecting line 14. Specifically, the air duct 12 is integrally constructed inside the indoor unit housing 11 and arranged along its height direction, the water receiving tray 13 is integrally constructed at the lower part of the air duct 12 for receiving condensed water, and the connecting line 14 is arranged in the air duct 12 and arranged along its height direction. The water leakage prevention device 2 generally includes a bending structure 21 and a fixing component 22. The bending structure 21 is formed at the lower part of the connecting line 14 and is located above the water receiving tray 13, and is used to gather condensed water on the outer wall of the connecting line 14. The fixing component 22 is installed on the bending structure 21 and is integrally formed with the indoor unit housing 11, and is used to position the bending structure 21.

[0041] The anti-water leakage device for an air conditioner of the present invention is configured such that the lower portion of the connecting line 14 is formed into a bending structure 21, and the bending structure 21 is fixed by a fixing assembly 22. Condensed water on the connecting line 14 can be gathered on the bending structure 21 and drip into the water receiving tray 13 located below the bending structure 21, thereby preventing the condensed water from dripping onto the outside of the water receiving tray 13, thereby preventing the air conditioner 1 from leaking.

[0042] Specifically, the indoor unit housing 11, the air duct 12, the water tray 13 and the connecting wire 14 are all existing. The upper and lower ends of the connecting wire 14 are fixed by a plurality of general buckles 15. The specific number of the connecting wire 14 can be determined according to demand, and the number of the general buckles 15 is also determined according to demand.

[0043] See also Figure 1 In the preferred embodiment of the anti-water leakage device for air conditioner, the bending structure 21 generally includes a first bend 211 and a second bend 212 connected to each other. The first bend 211 is formed at the lower part of the connecting line 14 and located above the water receiving tray 13, and the second bend 212 is formed at the lower part of the connecting line 14 and located above the first bend 211.

[0044] Specifically, the condensed water on the outer wall of the connecting line 14 above the first bend 211 will not continue to flow downward when it reaches the first bend 211, and the condensed water will be concentrated on the first bend 211. When the condensed water is concentrated, it will drip into the water receiving tray 13, thus avoiding water leakage of the air conditioner 1. The formation of the second bend 212 is conducive to the condensed water to gather on the first bend 211 and not continue to flow downward.

[0045] In this embodiment, the bending structure 21 is in a transverse “S” shape.

[0046] See also Figure 1 In the preferred embodiment of the anti-water leakage device for air conditioner, the bending direction of the first bend 211 is toward the water receiving pan 13, so that the condensed water drips into the water receiving pan 13. The bottom end of the first bend 211 is close to the water receiving pan 13 to prevent the condensed water from splashing out. The distance between the bottom end of the first bend 211 and the water receiving pan 13 is determined according to the actual situation and is not set here.

[0047] In the preferred embodiment of the anti-water leakage device for air conditioner, the bending direction of the second bend 212 is opposite to the bending direction of the first bend 211 to prevent condensed water from flowing to the first bend 211 and then continuing to flow downward.

[0048] Continue reading Figure 1 In the preferred embodiment of the anti-water leakage device for air conditioner, the fixing assembly 22 generally includes a first buckle 221 and a second buckle 222. The first buckle 221 is arranged on the first bend 211 and is integrally formed with the air duct 12, and is used to position the first bend 211. The second buckle 222 is arranged on the second bend 212 and is integrally formed with the air duct 12, and is used to position the second bend 212.

[0049] See also Figure 2In the preferred embodiment of the anti-water leakage device for air conditioner, the first buckle 221 generally includes a first sheet 2211, a first connecting sheet 2212, a first bending portion 2213, a first anti-external gap 2214 and a first anti-return clamping gap 2215. One end of the first connecting sheet 2212 is integrally formed with the middle of the rear of the first sheet 2211, and the other end of the first connecting sheet 2212 is integrally formed with the lower inner wall of the air duct 12, which is used to fix the first buckle 221. The first bending portion 2213 is pressed on one end of the first sheet 2211. The first anti-return clamping gap 2215 is formed between the first bending portion 2213 and one side of the rear of the first sheet 2211, one side of the first connecting sheet 2212, and the lower inner wall of the air duct 12, and is used for the connecting line 14 on one side of the first bend 211 to be clamped into the first anti-return clamping gap 2215 to prevent the connecting line 14 on one side of the first bend 211 from bending back. A first anti-externalization gap 2214 is formed between the other side of the back of the first sheet 2211, the other side of the first connecting sheet 2212, and the lower inner wall of the air duct 12, for inserting the connecting line 14 on the other side of the first bend 211 into the first anti-externalization gap 2214 to prevent the connecting line 14 on the other side of the first bend 211 from everting outward.

[0050] By providing the first sheet 2211, the first connecting sheet 2212, the first bending portion 2213, the first anti-externalization gap 2214 and the first anti-returning clamping gap 2215, the first bend 211 can be fixed and the first bend 211 can be prevented from returning to a vertical state.

[0051] Specifically, the first piece 2211 is arc-shaped, and its curvature is similar to that of the lower inner wall of the air duct 12, so as to avoid the first piece 2211 and the indoor unit housing 11 from being in compression contact. The length of the first connecting piece 2212 is slightly larger than the cross-sectional diameter of all the connecting wires 14 combined together, so that all the connecting wires 14 can be clamped.

[0052] Continue reading Figure 2 In this embodiment, the first bending portion 2213 includes a first folding piece 22133, a second folding piece 22132 and a first angle 22131. The first folding piece 22133 and the second folding piece 22132 are pressed on one end of the first piece 2211, so that a first angle 22131 extending toward the rear of the first piece 2211 is formed between the first folding piece 22133 and the second folding piece 22132. The first angle 22131 can limit the connecting line 14 within the first anti-return clamping gap 2215 to prevent the connecting line 14 of the first bend 211 from being reversed.

[0053] It should be noted that the present invention does not impose any restrictions on the material of the first piece 2211, which can be an elastic plastic material or an elastic, rust-proof metal material, to ensure that the connecting line 14 on one side of the first bend 211 can enter the first anti-backbend clamping gap 2215, and the connecting line 14 on the other side of the first bend 211 can enter the first anti-eversion gap 2214.

[0054] It should be noted that the present invention does not impose any limitation on the specific size of the first buckle 221 , and those skilled in the art may set the size according to actual conditions.

[0055] Continue reading Figure 2 In the preferred embodiment of the anti-water leakage device for air conditioner, the first buckle 221 also includes a water retaining rib 2216 extending above the first connecting piece 2212. The water retaining rib 2216 generally includes a first inclined section 22161, a second inclined section 22162 and a straight section 22163 formed in one piece. The first inclined section 22161 and the second inclined section 22162 are located at the upper part and inclined outward, and the straight section 22163 is located at the lower part and formed in one piece with the upper edge of the first connecting piece 2212. The first inclined section 22161 and the second inclined section 22162 are used to receive the condensed water dripping from the connecting line 14 located above the first bend 211 and flow along the straight section 22163 to the first bend 211. By providing the first inclined section 22161, the second inclined section 22162 and the straight section 22163, the condensed water dripping from the connecting line 14 above the first bend 211 can be guided to the first bend 211 and dripped onto the water receiving tray 13 without causing water leakage.

[0056] It should be noted that the inclination angles of the first inclined section 22161 and the second inclined section 22162 toward the outside can be determined according to actual needs.

[0057] Furthermore, the straight section 22163 and the upper edge of the first connecting piece 2212 are vertically connected.

[0058] Continue reading Figure 2 In this embodiment, the widths of the upper parts of the first inclined section 22161, the second inclined section 22162 and the straight section 22163 are slightly larger than the lower width of the straight section 22163, which can increase the area for receiving the condensed water dripping from the connecting line 14 above the first bend 211, and can directly flow to the first bend 211 without dripping onto the outer side of the first bend 211.

[0059] See also Figure 3In the preferred embodiment of the anti-water leakage device for air conditioner, the second buckle 222 generally includes a second piece 2221, a third piece 2222, a second connecting piece 2223, a second bending portion 2224, a third bending portion 2225, a second anti-outward gap 2226, and a second anti-backward clamping gap 2227. Among them, the front end of the second connecting piece 2223 and the middle part of the back of the second piece 2221 are integrally formed, and the rear end of the second connecting piece 2223 and one end of the third piece 2222 are integrally formed. One end of the second piece 2221 is located outside the second connecting piece 2223, and the other end of the second piece 2221 has a second bending portion 2224. The other end of the third piece 2222 has a third bending portion 2225, and the third bending portion 2225 and the second bending portion 2224 are arranged on the same side. The second bending portion 2224, one side of the rear of the second sheet 2221, one side of the second connecting sheet 2223, the front of the third sheet 2222, and the third bending portion 2225 form a second anti-return clamping gap 2227, which is used for the connecting wire 14 on one side of the second bend 212 to be clamped into the second anti-return clamping gap 2227 to prevent the connecting wire 14 on one side of the second bend 212 from bending back. The other side of the rear of the second sheet 2221, the other side of the second connecting sheet 2223, and the lower inner wall of the air duct 12 form a second anti-external gap 2226, which is used for the connecting wire 14 on the other side of the second bend 212 to be clamped into the second anti-external gap 2226 to prevent the connecting wire 14 on the other side of the second bend 212 from turning outward.

[0060] The second bend 212 can be fixed by arranging the second piece 2221, the third piece 2222, the second connecting piece 2223, the second bending portion 2224, the third bending portion 2225, the second anti-eversion gap 2226 and the second anti-return clamping gap 2227 to prevent the second bend 212 from returning to a vertical state.

[0061] See also Figure 3 In this embodiment, the second bending portion 2224 includes a third folding piece 22241, a fourth folding piece 22242 and a second angle 22243. The third folding piece 22241 and the fourth folding piece 22242 are pressed on the other end of the second piece 2221, so that a second angle 22243 extending toward the rear of the second piece 2221 is formed between the third folding piece 22241 and the fourth folding piece 22242. The second angle 22243 can limit the connecting line 14 within the second anti-return clamping gap 2227, so as to prevent the connecting line 14 of the second bend 212 from being reversed.

[0062] Continue reading Figure 3In this embodiment, the third bending portion 2225 includes a fifth folding piece 22251 and a third angle 22252. The fifth folding piece 22251 is integrally formed on the other end of the third piece 2222, and a third angle 22252 is formed between the fifth folding piece 22251 and the other end of the third piece 2222, so as to prevent the connecting line 14 of the second bend 212 from bending back.

[0063] It should be noted that the present invention does not impose any restrictions on the materials of the second piece 2221 and the third piece 2222, which can be made of elastic plastic material or elastic and rust-proof metal material, to ensure that the connecting line 14 on one side of the second bend 212 can enter the second anti-backbend clamping gap 2227, and the connecting line 14 on the other side of the second bend 212 can enter the second anti-eversion gap 2226.
