Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a waterproof and insect-proof structure of an air conditioning outdoor unit and an air conditioner. Background Art

[0002] With the development of air conditioning technology, users have higher and higher requirements for the quality of air conditioners. The outdoor unit of the air conditioner is mostly in the outdoor environment. The top cover of the outdoor unit is provided with reinforcing ribs for strength reasons. The reinforcing ribs make the gap between the top cover and the electric control box and the partition uneven. If there is moisture when the fan is running, it will enter the space between the electric control box and the compressor through the gap between the top cover and the electric control box and the partition, which is easy to damage the controller of the outdoor unit of the air conditioner or electrical devices such as the compressor; and insects can easily pass through the above gaps to enter the electric control box and damage the controller.

[0003] At present, the commonly used roof cover sponge cannot effectively seal the gap between the roof cover and the electric control box and the partition, and the soft sponge easily absorbs water and cannot effectively play a water-isolating role.

[0004] It can be seen from this that the waterproof and insect-proof structure of the outdoor unit needs to be improved. Summary of the invention

[0005] The problem solved by the invention is that there are uneven gaps between the top cover plate and the partition plate of the existing outdoor unit and the electric control box, and the space where the electric control box and the compressor are located is prone to water and insects.

[0006] In order to solve the above problems, the present invention provides a waterproof and insect-proof structure of an air conditioner outdoor unit, comprising a combined sponge, wherein the combined sponge comprises a closed-cell sponge and an open-cell sponge, the surface of the open-cell sponge is hydrophobic, and the closed-cell sponge and the open-cell sponge are overlapped to form the combined sponge;

[0007] When the top cover plate, electric control box and partition of the air conditioner outdoor unit are installed in place, the combined sponge is located between the top cover plate and the partition and between the top cover plate and the electric control box, the closed-cell sponge is suitable for fitting with the electric control box and the partition, the open-cell sponge is suitable for fitting with the top cover plate, and the open-cell sponge is suitable for filling the groove formed by the ribs of the top cover plate.

[0008] By combining sponges, the gap between the top cover plate and the partition plate, as well as the gap between the top cover plate and the electric control box are blocked, the grooves between the ribs of the top cover plate can be better filled, and only soft open-hole sponges are arranged between the partition plate and the top cover plate, which greatly reduces the cost, has a simple structure, and is easy to implement.

[0009] Optionally, the waterproof and insect-proof structure further includes drainage ribs, which are arranged on the top surface where the electric control box and the closed-cell sponge are in contact, and can effectively prevent water droplets condensed on the closed-cell sponge from dripping onto components of the electric control box, thereby improving the waterproof effect.

[0010] Optionally, there are multiple drainage ribs, and the multiple drainage ribs form a water guide groove, the opening of the water guide groove faces the rear side of the air-conditioning outdoor unit, so that the collected water flows to the rear side of the air-conditioning outdoor unit to prevent damage to components of the electric control box.

[0011] Optionally, the bottom surface of the water guide groove is tilted downward from front to back, so that water drops drip toward the rear side of the outdoor unit under the action of gravity.

[0012] Optionally, the waterproof and insect-proof structure further includes a blocking portion, which is arranged at the connecting corner between the partition and the front panel to improve the sealing performance at the corner between the partition and the front panel and prevent the formation of a gap at the corner between the partition and the front panel.

[0013] Optionally, the blocking portion includes a baffle, the baffle is seamlessly connected to the front panel, and the baffle is seamlessly connected to the partition, with a simple structure and strong sealing performance.

[0014] Optionally, the baffle and the partition are integrally formed, so that the structure is more solid and the manufacturing process is simple.

[0015] Optionally, the waterproof and insect-proof structure further includes a positioning convex bump, which is arranged on the folded edge of the top cover plate. The positioning convex bump is suitable for limiting the position of the combined sponge fixed on the top cover plate, effectively preventing the sponge from being misplaced and improving the installation accuracy of the sponge.

[0016] Optionally, the closed-cell sponge is provided with a notch, and when the closed-cell sponge is attached to the electric control box, the notch is located above the heat dissipation element of the electric control box to prevent water droplets condensed on the closed-cell sponge from dripping onto the heat dissipation element.

[0017] Optionally, the thickness D2 of the open-pored sponge is greater than the height of the groove;

[0018] And / or, the thickness D1 of the closed-cell sponge is greater than the gap between the ribs of the top cover plate and the partition plate.

[0019] Make sure the open-cell sponge and closed-cell sponge can be squeezed to provide better waterproof performance.

[0020] An air conditioner comprises an outdoor unit, wherein the outdoor unit comprises any of the above-mentioned waterproof and insect-proof structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] As an air-conditioning equipment installed in an outdoor environment, the top cover plate of the air-conditioning outdoor unit needs to ensure a certain strength and needs to be provided with certain reinforcing ribs. The usual method is to stretch the top cover plate so that there is a spaced groove on the side of the top cover plate facing the partition, and the extension direction of the groove is perpendicular to the plane where the partition is located, so that the gap spacing between the partition and the top cover plate is not uniform. The existing soft sponge is difficult to seal the gap formed between the partition and the groove, and moisture can easily pass through the gap into the space where the controller and the compressor are located.

[0031] The electric control box serves as the installation shell of the controller. When moisture drips onto the electric control box, if it is not handled, it is easy to enter the electric control box and damage the circuit system. Therefore, according to the different structures between the top cover plate and the partition plate, and between the top cover plate and the electric control box, as well as different protection requirements, the waterproof and insect-proof structure needs to be designed accordingly.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] This embodiment provides a waterproof and insect-proof structure for an air conditioner outdoor unit. Figure 1-Figure 7As shown, it includes a combined sponge 1. When the outdoor unit is assembled, the combined sponge 1 is arranged between the top cover plate 2, the electric control box 3 and the partition plate 4.

[0034] Specifically, the combined sponge 1 includes a closed-pore sponge 11 and an open-pore sponge 12. The closed-pore sponge 11 is a rubber sponge whose pores are not connected. Specifically, the closed-pore sponge of the present invention has a granular surface, has excellent hydrophobic and waterproof properties, and has a hard texture; the open-pore sponge is a rubber sponge whose pores are connected. Specifically, the open-pore sponge of the present invention has a hydrophobic surface, which can be made hydrophobic by surface treatment, such as applying a hydrophobic layer.

[0035] Combination Figure 2 As shown, the closed-cell sponge 11 and the open-cell sponge 12 are overlapped to form a combined sponge 1. The closed-cell sponge 11 is a layered structure, and the open-cell sponge 12 is a strip structure. Optionally, the open-cell sponge 12 may also be a layered structure, but the open-cell sponge 12 serves to isolate the gap between the top cover plate 2 and the partition plate 4. The open-cell sponge 12 with a strip structure can achieve a better effect, and there is no need to increase the cost of using the layered open-cell sponge 12.

[0036] Specifically, when the outdoor unit top cover plate 2, the electric control box 3 and the partition 4 are installed in place, the combined sponge 1 is located between the top cover plate 2 and the electric control box 3 and between the top cover plate 2 and the partition 4, and the closed-cell sponge 11 is a layered structure that can fit well on the upper surfaces of the electric control box 3 and the partition 4.

[0037] Preferably, the closed-cell sponge 11 can be made of PE sponge, and the surface has certain particles, so that the surface where the closed-cell sponge 11 fits the electric control box 3 and the partition 4 has a granular feel. Since the closed-cell sponge 11 has good waterproof and hydrophobic properties and a hard texture, it can better prevent water from being on the electric control box 3, and also effectively prevent insects from entering due to gaps between the electric control box 3 and the partition 4 and the top cover plate 2, thereby protecting devices such as the controller and the compressor. In addition, the closed-cell sponge 11 with a certain hardness can also be better squeezed between the top cover plate 2 and the electric control box 3, and also has a certain effect on fixing the electric control box 3.

[0038] Specifically, when the outdoor unit top cover plate 2, the electric control box 3 and the partition plate 4 are installed in place, the perforated sponge 12 is located between the top cover plate 2 and the partition plate 4, close to the top cover plate 2. Preferably, the perforated sponge 12 is in the shape of a long strip, the length direction of the perforated sponge 12 extends along the top edge of the partition plate 4, and the perforated sponge 12 fits the top cover plate 2.

[0039] Preferably, the open-pored sponge 12 is glued and fixed to the top cover plate 2. Before the top cover plate 2 is installed, the open-pored sponge 12 can also be fixed to the top cover plate 2 by glue, and then the top cover plate 2 is installed, to prevent the open-pored sponge 12 from being misplaced when the top cover plate 2 is installed, thereby preventing a gap from being generated between the top cover plate 2 and the partition plate 4, thereby improving the sealing performance of the open-pored sponge 12 on the gap between the top cover plate 2 and the partition plate 4.

[0040] Preferably, the open-cell sponge 12 includes slow-rebound rubber (NBR), which has good hydrophobicity, a smooth surface that allows water to flow easily, and a soft texture, which is suitable for filling, especially for the multiple grooves 23 on the top cover plate 2. Figure 1 As shown, when the open-cell sponge 12 is connected to the top cover plate 2, the extrusion effect between the top cover plate 2 and the partition plate 4 enables the open-cell sponge 12 to be embedded and filled in the groove 23, and combined with the overlapping part of the closed-cell sponge 11, the gap between the top cover plate 2 and the partition plate 4 is effectively blocked.

[0041] Better, combined Figure 2 As shown, the thickness D1 of the closed-cell sponge 11 is greater than the gap between the ribs of the top cover plate 2 (the ribs are reinforcing ribs between the grooves 23, formed by stretching the top cover plate 2 toward the bottom) and the electric control box 3. The thickness of the closed-cell sponge 11 is greater than the gap between the ribs of the top cover plate 2 and the electric control box 3, so that the closed-cell sponge 11 can be squeezed after the top cover plate 2 and the electric control box 3 are installed in place, thereby improving the water-proof and insect-proof effect of the closed-cell sponge 11.

[0042] Similarly, combined Figure 2 As shown, the thickness D2 of the open-cell sponge 12 is greater than the height of the groove 23 in the top cover plate 2. Since there is a groove 23 on the top cover plate 2, the thickness D2 of the open-cell sponge 12 is greater than the height of the groove 23. Therefore, after the top cover plate 2 and the partition plate 4 are installed in place, the top cover plate 2 and the partition plate 4 can squeeze the closed-cell sponge 11 and the open-cell sponge 12, and the open-cell sponge 12 is embedded in the groove 23 and filled in the groove 23, thereby improving the water-proof and insect-proof effect of the open-cell sponge 12.

[0043] Preferably, the closed-cell sponge 11 and the open-cell sponge 12 can be fixedly connected, such as by gluing them together, to facilitate installation.

[0044] It should be noted that, combined with Figure 2 As shown, the closed-cell sponge 11 and the open-cell sponge 12 overlap to a certain extent, so that the closed-cell sponge 11 and the open-cell sponge 12 exist between the top cover plate 2 and the partition plate 4 at the same time, the closed-cell sponge 11 of the overlapping part is in contact with the partition plate 4, and the open-cell sponge 12 of the overlapping part is in contact with the top cover plate 2, thereby improving the blocking effect of the combined sponge 1 on the gap between the top cover plate 2 and the partition plate 4 and enhancing the waterproof and insect-proof properties.

[0045] Preferably, the waterproof and insect-proof structure further includes drainage ribs 31, combined with Figure 4 and Figure 6 As shown, when the closed-cell sponge 11 contacts the surface of the electric control box 3, no matter how tightly it is pressed, there will be a gap that is invisible to the human eye. At this time, if there is water at the wind circle of the fan blades and washes toward the electric control box 3 and the top of the top cover plate 2, there will be a pressure difference on both sides of the partition 4, and the water mist will move between the electric control box 3 and the closed-cell sponge 11 of the top cover plate 2, and condense into water droplets, which are easy to drip onto the electric control box 3 or the compressor, causing damage to electrical components. Specifically, the drainage ribs 31 are arranged on the top surface where the electric control box 3 and the closed-cell sponge 11 are in contact. The drainage ribs 31 are ribs protruding upward on the top surface of the electric control box 3, which can guide the water accumulated on the upper part of the electric control box 3. There are multiple drainage ribs 31, and the multiple drainage ribs 31 form a water guide groove 32 structure. Specifically, combined with Figure 6 As shown, the drainage rib 31 includes a curved rib and 5 parallel ribs (4 ribs are shown in the figure, and there are 5 ribs on the electric control box of this embodiment), the curved rib matches the front side shape of the electric control box 3, and the curved rib and the parallel ribs constitute 4 water guide grooves 32. The openings of the water guide grooves 32 face the rear side of the air-conditioning outdoor unit, so that the water above the electric control box 3 can flow to the rear side of the electric control box 3, preventing the moisture on the electric control box 3 from entering the front part of the electric control box 3, thereby protecting the electrical components on the front side of the electric control box 3.

[0046] Preferably, in order to improve the guiding property of the water guide groove 32, the bottom surface of the water guide groove 32 is inclined, and the bottom surface of the water guide groove 32 is inclined downward from front to back, so that the water in the water guide groove 32 can automatically flow to the rear side of the electric control box 3 under the action of gravity, thereby improving the degree of protection of the water guide groove 32 to the electrical components.

[0047] Better, combined Figure 5 As shown, the waterproof and insect-proof structure also includes a blocking portion 41, which is arranged at the corner where the partition 4 and the front panel 5 are connected. In the existing structure of the air-conditioning outdoor unit, the upper top edge of the partition 4 is lower than the edge height of the front panel 5, so that there is a step-like structure at the corner where the partition 4 and the front panel 5 are connected. When the open-pore sponge 12 here is squeezed by the top cover plate 2 and the partition 4, it is easy to form a gap due to deformation, and it is impossible to achieve complete sealing waterproof and insect-proof. To solve this problem, a blocking portion 41 is arranged at the corner where the partition 4 and the front panel 5 are connected, and the space at the corner where the partition 4 and the front panel 5 are connected is blocked in advance. The open-pore sponge 12 contacts and squeezes the blocking portion 41, and no new gap will appear at the corner.

[0048] Specifically, the blocking portion 41 has various structures, which may be plate-shaped, block-shaped or irregularly shaped. Preferably, the blocking portion 41 includes a baffle ( Figure 5The plate-shaped structure shown in the figure), the baffle can be a flat plate or an arc-shaped plate. In this embodiment, the baffle 5 is a flat plate. The baffle is seamlessly connected to the front panel 5, and the baffle is seamlessly connected to the partition 4. Seamless connection means that there is no gap when connected, and the gap is not easy for water and insects to pass through. Specifically, multiple methods such as seamless welding or applying connecting glue can be used. The baffle can block the corner where the front panel 5 and the partition 4 are connected. The angle of the baffle is not limited. The angle that can play a blocking role falls within the protection scope of the present invention. However, it is better that the baffle is parallel to the partition 4, and the material for making the baffle is saved while ensuring the blocking effect.

[0049] Preferably, the baffle is integrally formed with the partition 4, and the baffle is a raised portion extending upward from the partition 4, and the raised portion of the baffle is in close contact with the front panel 5, and in close contact with the upper flange of the front panel 5, thereby improving the blocking effect of the baffle on the corner where the partition 4 and the front panel 5 are connected, and improving the waterproof and insect-proof effects.

[0050] Preferably, the waterproof and insect-proof structure further includes a positioning convex bump 21, combined with Figure 7 As described, the positioning convex bump 21 is arranged on the folded edge 22 of the top cover plate 2. The positioning convex bump 21 may be one or more. When pasting the perforated sponge 12 and the top cover plate 2, positioning is performed through the positioning convex bump 21. Specifically, one top corner of the perforated sponge 12 may be aligned with the positioning convex bump 21 for pasting. Because when pasting the perforated sponge 12, the top cover plate 2 and the partition plate 4 are separated, the operator cannot accurately and quickly obtain the pasting position of the perforated sponge 12. The positioning convex bump 21 can better prevent the position of the perforated sponge 12 from being offset, so that the perforated sponge 12 can be squeezed by the top cover plate 2 and the partition plate 4, thereby improving the waterproof and insect-proof effects.

[0051] Preferably, the closed-cell sponge 11 is a lamellar structure, combined with Figure 1-Figure 3 As shown, the closed-cell sponge 11 is provided with a notch 111. The shape of the notch 111 is not fixed, but when the closed-cell sponge 11 is fitted to the electric control box 3, the notch 111 is located above the heat dissipation element of the electric control box 3. The notch 111 can prevent the condensed water droplets of the closed-cell sponge 11 from dripping onto the heat dissipation element, while reducing the degree of obstruction of the closed-cell sponge 11 to the heat dissipation of the heat dissipation element of the electric control box 3.

[0052] Optionally, the open-pore sponge 12 can also be made of other materials such as pearl cotton or LC, which has low cost, light weight, good water-proof effect and high environmental protection. LC is an open-pore polyethylene foam material, which is a polyethylene resin modified into a mesh-like polymer structure through chemical cross-linking.

[0053] Based on the description of the waterproof and insect-proof structure above, the present invention further provides an air conditioner, the air conditioner includes an outdoor unit, and the outdoor unit includes the waterproof and insect-proof structure described above.

[0054] The beneficial effects of the air conditioner compared to the prior art are the same as those of the waterproof and insect-proof structure, which will not be repeated here.

[0055] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
