Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a waterproof grille of air conditioning equipment and the air conditioning equipment. Background Art

[0002] When air passes through the air duct of the air conditioning equipment, the low-temperature refrigerant in the evaporator absorbs the heat in the air, thereby lowering the temperature of the air and allowing the fan to discharge cold air.

[0003] During the cooling operation of the air conditioner, condensed water will be generated on the surface of the evaporator. In the air conditioner operation mode with a large air volume, the condensed water is easily blown away from the evaporator surface by the high-speed air flow. The water droplets blown away by the air will cause damage to the internal electrical components and circuits of the machine or cause rust and corrosion of metal parts. In addition, the condensed water blown out from the air outlet of the air conditioner will flow out to the outside, causing pollution or corrosion in indoor places.

[0004] The anti-blow water structure in the existing air-conditioning equipment is usually a baffle or a filtering structure such as a hydrophobic membrane. Although it can achieve a certain water-proof function, it will seriously block the air duct and cause a large loss of air volume. Summary of the invention

[0007] According to a waterproof grille of an air-conditioning equipment provided by the present invention, in a plane perpendicular to the first air guide grille and the second air guide grille, the cross-sectional shape of the first air guide grille and the second air guide grille is an arc; in the length direction X, the arc surfaces of the first air guide grille and the second air guide grille are oriented in the same direction; in the thickness direction Y, the outer arc surface of the first air guide grille blocks at least one half of the air inlet opening, and the inner arc surface of the second air guide grille blocks at least another half of the air inlet opening.

[0008] According to a waterproof grille of an air-conditioning device provided by the present invention, the outer curved surface of the first air guide grille and / or the inner curved surface of the second air guide grille are / is a corrugated surface.

[0009] According to a waterproof grille of an air-conditioning equipment provided by the present invention, in the thickness direction Y, the top plate and the bottom plate have the same board width, the first projection lengths of the first air guide grille and the second air guide grille are the same; the board width is greater than the first projection length and greater than half of the board width.

[0010] According to a waterproof grille of an air-conditioning equipment provided by the present invention, in the length direction X, the second projection lengths of the first air guide grille and the second air guide grille are the same, the opening sizes of the air inlet opening and the air outlet opening are the same; the opening size is greater than the second projection length and is greater than or equal to one half of the opening size.

[0011] According to a waterproof grille of an air-conditioning equipment provided by the present invention, when the waterproof grille is in use, the top plate is located above the gravity direction, and the bottom plate is located below the gravity direction; the bottom plate is provided with an elongated hole extending along the length direction X.

[0012] The present invention also provides an air-conditioning device, in which an evaporator, a waterproof grille and a fan are arranged in the air duct of the air-conditioning device, and the waterproof grille is the waterproof grille of any of the above-mentioned air-conditioning devices; when the fan is working, the air passes through the evaporator and the waterproof grille in turn, and is finally discharged from the air-conditioning device through the fan.

[0013] According to an air conditioning device provided by the present invention, a bracket for installing the waterproof grille is provided in the air duct, and the bracket has a mounting groove for limiting the position of the waterproof grille in the thickness direction Y.

Therefore, the waterproof grille is applied to air-conditioning equipment to reduce the risk of water blowing during the operation of the air-conditioning equipment while having a small impact on the air volume of the air-conditioning equipment, thereby improving the safety of the air-conditioning equipment.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] During the cooling operation of air-conditioning equipment, condensed water will be generated on the surface of the evaporator. Under high air volume conditions, the condensed water will be blown out from the surface of the heat-conducting fins of the evaporator by high-speed wind. The problem of condensed water flying is an important quality problem of air-conditioning products. Uncontrollable water flying will cause damage to the internal power components and circuits of the machine or cause rust and corrosion of metal parts. At the same time, the water blown out from the air outlet of the machine will flow out of the air duct, causing pollution or corrosion to the user's installation site and the surface of the building.

[0028] The present invention aims to provide a new solution for preventing water from blowing out, which includes a waterproof grille for air-conditioning equipment that prevents water from blowing out and air-conditioning equipment installed with the waterproof grille, which can meet the function of blocking the condensation water of the evaporator. At the same time, the waterproof grille of the air-conditioning equipment in this solution has less effect on the air volume of the air-conditioning equipment than traditional baffles and water filtering mechanisms.

[0029] Combine the following Figure 1-Figure 6 A waterproof grille for an air conditioner and an air conditioner according to a preferred embodiment of the present invention are described.

[0030] like Figure 1 As shown, the waterproof grille of the air conditioner includes a top plate 101, a bottom plate 102, a first air guide grille 111 and a second air guide grille 112. The top plate 101 and the bottom plate 102 are used to fix the first air guide grille 111 and the second air guide grille 112 between the top plate 101 and the bottom plate 102.

[0031] like Figure 2 and Figure 3As shown, a plurality of first air guide grilles 111 are evenly distributed in the length direction X of the waterproof grille, and an air inlet opening 121 is formed between adjacent first air guide grilles 111; a plurality of second air guide grilles 112 are evenly distributed in the length direction of the waterproof grille, and are arranged alternately with the first air guide grilles 111, and an air outlet opening 122 is formed between adjacent second air guide grilles 112. It can be understood that the terms "first", "second", etc. in the present invention are only used to facilitate the understanding of the technical solution, and do not limit the scope of protection of the present invention. In practical applications, the names of the components corresponding to the terms "first", "second", etc. are interchangeable, and accordingly, the air inlet opening 121 and the air outlet opening 122 can be determined according to the actual air flow direction in actual use.

[0032] The first air guide grille 111 and the second air guide grille 112 are preferably arc-shaped plates with the same shape and symmetrically arranged in the dislocation direction. The dislocation symmetry mentioned here means that the first air guide grille 111 and the second air guide grille 112 are staggered and alternately distributed in the length direction X, and the swing angles of any first air guide grille 111 and any second air guide grille 112 are symmetrical relative to the length direction X.

[0033] like Figure 3 As shown, when the air enters the air inlet opening 121 along the thickness direction Y, the outer arc surface of the first air guide grille 111 forms an arc-shaped turbulent flow effect on a part of the air, and the water droplets in the air are adsorbed on the outer arc surface of the first air guide grille 111 under the action of inertia; at the same time, the inner arc surface of the second air guide grille 112 also forms an arc-shaped turbulent flow effect on the air, and the water droplets in the air are adsorbed on the inner arc surface of the second air guide grille 112 under the action of inertia. The air is only disturbed by the first air guide grille 111 and the second air guide grille 112 in the process of moving from the air inlet opening 121 to the air outlet opening 122, and the air discharged from the air outlet opening 122 can still basically maintain the original wind direction and continue to move, with little impact on the air volume and wind speed. Therefore, the waterproof grille of the air conditioner can reduce the risk of water blowing of the air passing through the waterproof grille while having little impact on the air volume.

[0034] like Figure 4 and Figure 5As shown, the waterproof grille of the air conditioner is arranged inside the air conditioner, behind the air outlet surface of the evaporator 201. During the operation of the air conditioner in the cooling mode, the fan 202 causes the air to form a wind flow along the air duct. The high-speed wind containing water blown out from the evaporator 201 passes through the waterproof grille. Since the first air guide grille 111 and the second air guide grille 112 are arranged in a staggered manner, the wind can be blown out from the rear of the waterproof grille after passing through the surface of the grille and guided by the arc. The water droplets contained therein have a large volume and mass, and their inertia is relatively large. When they encounter the guidance of the first air guide grille 111 and the second air guide grille 112, the movement trajectory is not easy to deflect, and they will hit and adhere to the surface of the first air guide grille 111 and the second air guide grille 112, gather into drops, and then drip along the first air guide grille 111 and the second air guide grille 112, and it is not easy to be blown to the side of the fan 202 with the air supply, so as to reduce the risk of water blowing during the operation of the air conditioner while having little impact on the air volume of the air conditioner, and improve the use safety of the air conditioner.

[0035] In order to better understand the above technical solution, the waterproof grille of the air-conditioning device and various specific implementations of the air-conditioning device of the present invention are described in detail below in conjunction with the drawings in the specification.

[0036] The present invention provides a waterproof grille for an air conditioner, which is used to be arranged between an evaporator and a fan of the air conditioner. Figure 1 , Figure 2 and Figure 3 As shown, it includes a top plate 101, a bottom plate 102, and a first air guide grille 111 and a second air guide grille 112 fixed between the top plate 101 and the bottom plate 102. The first air guide grille 111 and the second air guide grille 112 are respectively arranged near both sides of the thickness direction Y of the waterproof grille; a plurality of first air guide grilles 111 and a plurality of second air guide grilles 112 are alternately and evenly distributed in the length direction X of the waterproof grille; an air inlet opening 121 is formed between adjacent first air guide grilles 111, and an air outlet opening 122 is formed between adjacent second air guide grilles 112, and the directions of the air inlet opening 121 and the air outlet opening 122 are symmetrical with respect to the length direction X; in the thickness direction Y, the projection range of the adjacent first air guide grilles 111 and the second air guide grille 112 covers the air inlet opening 121, so that water droplets carried in the air can be fully removed when the air flows.

[0037] The waterproof grille of the air conditioner forms an air inlet opening 121 and an air outlet opening 122 staggered on both sides of the waterproof grille in the thickness direction Y through the staggered arrangement of the first air guide grille 111 and the second air guide grille 112. Since the projections of the first air guide grille 111 and the second air guide grille 112 in the thickness direction Y can cover the air inlet opening 121, when the air flows from the air inlet opening 121 to the air outlet opening 122, the water droplets in the flowing air are relatively large in volume and mass, and the inertia is relatively large, and the movement trajectory is not easy to deflect, so they will adhere to the surface of the first air guide grille 111 and the second air guide grille 112, gather into drops, and drip along the first air guide grille 111 or the second air guide grille 112, and will not be blown through the waterproof grille with the air supply. In this process, the waterproof grille only realizes a short-stroke turbulence effect on the flowing air in the thickness direction Y, which will not significantly change the flow direction of the air and has little effect on the flux of the air duct. Therefore, the waterproof grille is applied to the air-conditioning equipment, which can reduce the risk of water blowing during the operation of the air-conditioning equipment with little impact on the air volume of the air-conditioning equipment, thereby improving the safety of the air-conditioning equipment.

[0038] The first air guide grille 111 and the second air guide grille 112 may be inclined flat plate-like members, or partially inclined bent plate-like members, preferably as follows: Figure 1 , Figure 2 and Figure 3 The arc-shaped plate-like member shown.

[0039] According to the present invention, a waterproof grille of an air conditioning device is provided, such as Figure 2 and Figure 3 As shown, on a plane perpendicular to the first air guide grille 111 and the second air guide grille 112, the cross-sectional shape of the first air guide grille 111 and the second air guide grille 112 is an arc. Compared with other guide shapes, the arc-shaped guide has less resistance to air, and has less impact on the air volume of the air-conditioning equipment while preventing water from blowing. Preferably, in the length direction X, the arc surfaces of the first air guide grille 111 and the second air guide grille 112 face the same direction; in the thickness direction Y, the outer arc surface of the first air guide grille 111 blocks at least one-half of the air inlet opening 121, and the inner arc surface of the second air guide grille 112 blocks at least another half of the air inlet opening 121. According to this setting, the air entering from the air inlet opening 121 will at least be guided by the outer arc surface of the first air guide grille 111 or the inner arc surface of the second air guide grille 112 during the flow, thereby fully absorbing water droplets in the air and preventing water droplets, especially water droplets with large inertia, from passing through the waterproof grille.

[0040] According to a waterproof grille of an air conditioner provided by the present invention, on the basis of the above-mentioned arc design, the outer arc surface of the first air guide grille 111 and / or the inner arc surface of the second air guide grille 112 are corrugated surfaces. The surface corrugations can prevent water droplets from detaching from the waterproof grille under the blowing of air and falling to the other side of the waterproof cut when water droplets are adsorbed on the outer arc surface of the first air guide grille 111 and / or the inner arc surface of the second air guide grille 112. Moreover, after the water droplets gather, the corrugated shape extending along the length direction of the air guide grille can guide the water droplets, so that they move downward along the corrugations under the action of gravity. In order to enable the waterproof grille to function on both sides of the thickness direction Y, the inner arc surface and the outer arc surface of the first air guide grille 111 can be set as corrugated surfaces, and the inner arc surface and the outer arc surface of the second air guide grille 112 can be set as corrugated surfaces.

[0041] Preferably, the corrugated surface may be grooves formed on the outer curved surface of the first air guide grille 111 and / or the inner curved surface of the second air guide grille 112, or may be ridges on the outer curved surface of the first air guide grille 111 and / or the inner curved surface of the second air guide grille 112. The length direction of the grooves or ridges is consistent with the length direction of the air guide grille, and multiple grooves or ridges are evenly distributed on the outer curved surface of the first air guide grille 111 and / or the inner curved surface of the second air guide grille 112.

[0042] According to the waterproof grille of an air conditioner provided by the present invention, in the thickness direction Y, the top plate 101 and the bottom plate 102 have the same plate surface width, the first projection length of the first air guide grille 111 and the second air guide grille 112 are the same; the plate surface width is greater than the first projection length and greater than half of the plate surface width. According to this solution, Figure 3 As shown, the first projection length refers to the length of the first air guide grille 111 and the second air guide grille 112 in the thickness direction Y of the waterproof grille. Since the board width is greater than the first projection length and greater than half of the board width, when the first air guide grille 111 and the second air guide grille 112 are alternately distributed, a portion of the first air guide grille 111 is located between two adjacent second air guide grilles 112, and similarly, a portion of the second air guide grille 112 is located between two adjacent first air guide grilles 111, so that after the air enters the air inlet opening 121, it will be separated into two streams by the second air guide grille 112, thereby increasing the contact area between the air and the air guide grille structure.

[0043] According to a waterproof grille of an air conditioner provided by the present invention, in the length direction X, the second projection lengths of the first air guide grille 111 and the second air guide grille 112 are the same, and the opening sizes of the air inlet opening 121 and the air outlet opening 122 are the same; the opening size is greater than the second projection length and equal to one-half of the opening size. The second projection length refers to the size of the first air guide grille 111 and the second air guide grille 112 in the length direction X of the waterproof grille, respectively. Since the opening size is greater than the second projection length and equal to one-half of the opening size, the amplitude of air turbulence during the passage of air is small, and the first air guide grille 111 and the second air guide grille 112 can guide the flowing air respectively.

[0044] like Figure 2 and Figure 3 As shown, the waterproof grille of the present invention is composed of a top plate 101 and a bottom plate 102 and two rows of arc-shaped first air guide grilles 111 and second air guide grilles 112 connected in the middle, the arc surfaces of all the first air guide grilles 111 and the second air guide grilles 112 face the same direction, the starting points of the two rows of air guide grilles are respectively aligned with the two sides in the width direction of the bottom plate 102, and the end points are perpendicular to the sides where the starting points are located, 1 / 2 of the bottom plate width < the length of the perpendicular line segment < the bottom plate width, the two rows of air guide grilles are staggered, and a perpendicular line is drawn through the starting and end points of the air guide grilles to the long side of the bottom plate 102, the perpendicular line segment passing through the starting point of each air guide grille is located between the perpendicular line segments made through the starting and end points of the adjacent opposite air guide grilles, and the projections of the opposite adjacent air guide grilles in the length direction X overlap each other.

[0045] Preferably, the cross-sections of the first air guide grille 111 and the second air guide grille 112 of the waterproof grille are arc-shaped, and the centers of circles determined by the arcs of the plurality of first air guide grilles 111 and the second air guide grilles 112 are located on the same straight line along the length direction X, so that the arc surfaces between adjacent first air guide grilles 111 and the second air guide grilles 112 are arranged in parallel, so as to reduce the impact on air circulation while guiding the air arc turbulence.

[0046] According to a waterproof grille of an air conditioner provided by the present invention, when the waterproof grille is in use, the top plate 101 is located above the gravity direction, and the bottom plate 102 is located below the gravity direction; the bottom plate 102 is provided with an elongated hole extending along the length direction X. Water droplets in the air gather on the first air guide grille 111 and the second air guide grille 112, and under the action of gravity, the water droplets will slide downward along the first air guide grille 111 and the second air guide grille 112, and the elongated holes provided on the bottom plate 102 can be used to discharge the condensed water flowing on the bottom plate 102. In practical applications, it is connected to a drainage mechanism of the air conditioner, such as a condensed water collection tray or a drainage pipe.

[0047] The air conditioning device provided by the present invention is described below. The waterproof grilles of the air conditioning device described below and the air conditioning device described above can be referred to each other.

[0048] The present invention also provides an air conditioning device, such as Figure 4 As shown, an evaporator 201, a waterproof grille and a fan 202 are arranged in the air duct of the air-conditioning equipment, and the waterproof grille is the waterproof grille of any of the above-mentioned air-conditioning equipment; when the fan is working, the air passes through the evaporator and the waterproof grille in turn, and is finally discharged from the air-conditioning equipment through the fan.

[0049] When the air moves along the air duct, the water droplets in the flowing air are large in volume and mass, and their inertia is relatively large, so the movement trajectory is not easy to deflect, and they will adhere to the surface of the first air guide grille 111 and the second air guide grille 112 of the waterproof grille, gather into drops and drip along the first air guide grille 111 or the second air guide grille 112, and will not be blown through the waterproof grille with the air supply. In this process, the waterproof grille only achieves a short-stroke turbulence effect on the flowing air in the thickness direction Y, which will not significantly change the flow direction of the air, and has little effect on the flux of the air duct. Therefore, the air conditioning equipment can reduce the risk of water blowing during operation while having little effect on the air volume, thereby improving the safety of the air conditioning equipment.

[0050] like Figure 4 As shown, the water-blocking grille is located between the evaporator 201 and the fan 202. When the air conditioner is in cooling mode, air is sucked in from the evaporator 201 and blown out from the fan 202 under the drive of the fan 202. After cooling down through the evaporator 201, the water vapor carried in the air condenses when it is cold, and is carried by the high-speed wind and blown out from the back of the evaporator 201. When the wind containing water droplets passes through the water-blocking grille, due to the shielding and guiding effect of each of the first air guide grille 111 and the second air guide grille 112, the wind cannot pass through the water-blocking grille in the form of linear motion, and can only be forced to deflect along the gap between the first air guide grille 111 and the second air guide grille 112. The water droplets contained in the wind have a larger mass and volume than air molecules, and their inertia is relatively large. The water droplets will continue to move in a straight line under the action of inertia, and eventually hit the curved surfaces of the first air guide grille 111 and the second air guide grille 112, and are blocked from being blown out with the air supply. After gathering into larger water droplets, they drip along the grille under the action of gravity into the water receiving tray below.

[0051] According to an air conditioning device provided by the present invention, a bracket for mounting a waterproof grille is provided in the air duct, and the bracket has a mounting groove 203 for limiting the position of the waterproof grille in the thickness direction Y. The bracket is preferably provided at least at the top and bottom of the waterproof grille to respectively cooperate with the top plate 101 and the bottom plate 102 of the waterproof grille in a limited position mounting manner, and the mounting groove 203 has a structural form that matches the size and shape of the top plate 101 and the bottom plate 102. Preferably, as Figure 5As shown, the brackets are arranged on the inner walls of the air duct around the waterproof grille, and each has a mounting groove 203 facing the waterproof grille.

[0052] According to the present invention, an air conditioning device is provided, such as Figure 5 and Figure 6 As shown, the bracket preferably includes a bottom bracket 210, and the bottom bracket 210 includes a bearing surface 211, a water collecting tank 212 recessed relative to the bearing surface 211, and a limit plate 213 extending upward on both sides of the width direction of the bearing surface 211; the limit plate 213 and the bearing surface 211 form a mounting groove 203. In order to facilitate the discharge of condensed water intercepted by the waterproof grille, the bottom of the water collecting tank 212 is preferably evenly distributed with a plurality of water holes 214, and the water collecting tank 212 is connected to the condensed water collecting pan of the air conditioning equipment through the water holes 214.

[0053] According to the air conditioning device of the preferred embodiment, the water retaining grille installed in the air conditioning device is fixed by the brackets around it. Because the bottom bracket 210 is located at the bottom of the grille, water drops will eventually gather and fall on it. The structural form of the bottom bracket 210 also has certain requirements for drainage while meeting the support and limit. The entire bottom bracket 210 includes a bearing surface 211, a water collecting tank 212 recessed relative to the bearing surface 211, and a limit plate 213 extending upward on both sides of the width direction of the bearing surface 211, wherein the limit plate 213 and the bearing surface 211 form a mounting groove 203, and the waterproof grille is directly placed on this bearing surface 211, and is suspended from the water collecting tank 212, so that water drops will not be enriched between the water retaining grille and the bracket to cause corrosion of both. The water collecting tank 212 is provided with multiple water holes 214, so that the collected water is easy to discharge. The limit plates 213 on both sides are discontinuous, which can ensure that the waterproof grille is accurately positioned therein and will not be displaced by the wind. At the same time, the discontinuous structural form can also play a good drainage role and effectively avoid rust and corrosion after water storage.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
