DETAILED DESCRIPTION

Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawing. The following embodiments described with reference to the accompanying drawing are illustrative. It should be understood that the embodiments described are intended to explain the present application, but not to limit the present application.
Embodiments of the present application provide a water pan, the water pan is used for an air conditioner, which may improve the efficiency of air inlet and air outlet, has high overall structural stability, and may improve the convenience and accuracy of installation on an air conditioner. The air conditioner may be a central air conditioner, and the water pan may be installed on an indoor air inlet and outlet device of the central air conditioner.
Referring to FIG. 1 to FIG. 6, the water pan of embodiments of the present application mainly includes two parts of a plastic member 10 and a foaming member 20, and the two parts are connected as a whole and do not need to be connected by a screw and other connectors. Although the materials of the plastic member 10 and the foaming member 20 are different, they have an integrally formed structure, and there is no need to assemble separately when in use, thus improving the convenience of installation, improving production efficiency, and further facilitating improvement of the accuracy of the relative position between the air inlet 11 and a related component of the air conditioner.
Referring to FIG. 1 and FIG. 3, an air inlet 11 is defined in a middle of the plastic member 10, an air outlet 12 is defined near an edge of the plastic member 10, and a water receiving sink 17 is defined between the air inlet 11 and the air outlet 12. The water receiving sink 17 surrounds the air inlet 11, and the air outlet 12 continuously surrounds at least part of an outer edge of the water receiving sink 17. A plurality of supporting grilles 14 is arranged in the air outlet 12, and the plurality of supporting grilles 14 is distributed at intervals along an extension direction of the air outlet 12. In embodiments of the present application, only one air outlet 12 is provided, and continuously surrounds the water receiving sink 17, to form an annular air outlet, thus increasing the circulation area of the air outlet 12. Although the supporting grille 14 is arranged in the air outlet 12, the circulation area of the air outlet 12 occupied by the supporting grille 14 is very small, and the total circulation area of the air outlet 12 is far greater than the total circulation area of a plurality of air outlets provided in the related art. The water receiving sink 17 is arranged as a long strip shape and extends along a predetermined direction to contain the condensate water and transfer the collected condensate water to a preset pipe. In some embodiments, the water receiving sink 17 is a continuous recess, and the condensate water may flow within the water receiving sink 17. The supporting grille 14 is a plate-like body, and a thickness of the supporting grille 14 gradually decreases along an air outlet direction. That is, a width of a cross-section of the supporting grille 14 at different locations may be different. The setting may not only reduce wind resistance, but also has the effect of reducing noise.
In the related art, the water pan is made of foam, and the strength of foam is low, so at the air outlet, a long connection structure needs to be provided to connect a frame, which will cause a larger area of blocking to the air outlet.
In some embodiments, the foaming member 20 is integrally formed with the plastic member 10.
In the present application, the water pan is made by foaming a foam material on the plastic member, the strength of the plastic member is high, the strength of the water pan formed by the process is high, and the section of the supporting grille 14 for connecting a first frame 16 at the air outlet may be made very small. As shown in FIG. 3, the proportion of the wind shield area of the supporting grille 14 in the air outlet to the total area of the air outlet is very small, which may even be ignored, so that the annular air outlet may be achieved.
For example, the air outlet 12 is a bent long-strip hole with a certain length, and the width of the air outlet 12 may be set according to the actual design requirements.
The supporting grille 14 plays the role of supporting and connection, which may be made as thin as possible under the premise of meeting the structural strength requirements, to reduce wind resistance.
Referring to FIG. 2, the foaming member 20 and the plastic member 10 at least partially overlap with each other, which play a role of heat preservation, so that the water pan achieves the effect of anti-condensation. The foaming member 20 avoids the air inlet 11 and the air outlet 12. The foaming member 20 is connected with the plastic member 10 and is relatively fixed. In some embodiments, the foaming member 20 is integrally formed with the plastic member 10, the foaming member 20 defines the water receiving sink 17, the water receiving sink 17 surrounds the air inlet 11, and the air outlet 12 surrounds the water receiving sink 17. Since the foaming member 20 and the plastic members 10 are integrally formed, the foaming member 20 and the plastic members 10 also do not need to be assembled separately. Although the materials of the foaming member 20 and the plastic members 10 are different, they may be formed by injection molding. Therefore, the foaming member 20 and the plastic members 10 may be casted respectively by controlling the casting sequence of different materials, and the foaming member 20 and the plastic member 10 are connected as a whole.
In some embodiments, in order to avoid the air inlet 11 and the air outlet 12, an air inlet avoidance hole 23 is defined in a middle of the foaming member 20, and an air outlet avoidance hole 24 is defined between a second frame 25 and the water receiving sink 17. The air inlet avoidance hole 23 corresponds in position to the air inlet 11, and the air outlet avoidance hole 24 corresponds in position to the air outlet 12. The air inlet avoidance hole 23 is a circular shape matching the air inlet 11, and the air outlet avoidance hole 24 is a bent long strip-shaped hole matching the shape of the air outlet 12.
In some embodiments, the supporting grille 14 is arranged along a direction from the air inlet 11 to the air outlet 12, and a width of the supporting grille 14 ranges from 1.5 mm to 3.2 mm. Since the plastic member 10 is made entirely of plastic material, the width of the supporting grille 14 that is available for mold-opening may be controlled above 1.5 mm. According to the test and the needs of the structural strength of the water pan, in embodiments of the present application, the width of the supporting grille 14 is limited to 3.2 mm. Thus, the width of the supporting grille 14 may be 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3.0 mm, etc. The supporting grille 14 of the size not only has sufficient structural strength, but also causes very small wind resistance to the air outlet 12, which realizes a larger air outlet area and improves air outlet efficiency.
The width of the supporting grille 14 mentioned here refers to the thickness of the cross-section of the supporting grille 14 occupying the air outlet 12, that is, a distance between the two sides of the supporting grille 14 in FIG. 3. The supporting grille 14 is a plate-like body, where the width of the supporting grille 14 is the maximum thickness of the plate-like body.
The plastic member 10 mainly plays the role of structural support for the whole water pan, and the foaming member 20 mainly plays the role of heat preservation for the whole water pan. If the foaming member 20 is provided with the supporting grille, because of the nature of the material itself, it is difficult to control the width of the supporting grille between 1.5 mm and 3.2 mm, and in the related art, in the solution of the foaming member 20 provided with the supporting grille, the width of the provided supporting grille is usually about 10 mm, thus the wind resistance to the air outlet 12 is larger.
In some embodiments, the foaming member 20 and the plastic member 10 are integrally formed, and the integral forming of the plastic member 10 and the foaming member 20 may eliminate the assembly error and improve the fit clearance between an air guiding ring and a fan wheel of the air conditioner. The integral forming here means that the two are casted together during injection molding, so that the assembly step may be saved, the fit accuracy of the foaming member 20 and the plastic member 10 is good, and the individual difference of the water pan is small.
In some embodiments, the process method of the integral forming of the foaming member 20 and the plastic member 10 includes injection molding the plastic member 10, and directly casting a foam material on the plastic member 10 with a mold after the formed plastic member 10 is solidified, so that the foam material and the plastic member 10 are at least partially melted together, and the foam material is connected with the plastic member 10 after the foam material is solidified.
The structural strength of the plastic member 10 is greater than that of the foaming member 20. Therefore, the plastic member 10 is first injected molded, and the foam material is injected after the plastic member 10 is solidified to form the foaming member 20 on the plastic member 10. The plastic member 10 and the foaming member 20 are at least partially melted together, so that the plastic member 10 and the foaming member 20 form an integrally formed structure. Therefore, the plastic member 10 and the foaming member 20 are inseparable two parts, and they do not have to be installed separately during the production of the air conditioner, thus the relative position of the plastic member 10 and the foaming member 20 is very accurate, and no assembly errors will be generated.
When the foam material is casted, the surface of the plastic member 10 in contact with it may be partially melted, to fuse with the foam material into a whole. The part of the plastic member 10 in contact with the foaming member 20 may also not melt with each other.
In some embodiments, the width of the supporting grille 14 ranges from 2 mm to 3 mm, for example from 2 mm to 2.5 mm. The size of the supporting grille 14 not only has sufficient structural strength, but also causes very small wind resistance to the air outlet 12, which realizes a larger air outlet area and improves air outlet efficiency.
The plastic member 10 has a first frame 16, the supporting grille 14 has a first end connected to the first frame 16, and a second end connected to the middle of the plastic member 10. The first frame 16 is connected with the second frame 25, the first frame 16 plays a supporting role, and the second frame 25 plays a heat preservation role.
In some embodiments, a cross-section of the supporting grille 14 gradually decreases along the air outlet direction, that is, the width of the cross-section of the supporting grille 14 at different locations may not be equal. The setting further reduces wind resistance and has the effect of reducing noise. The directions of the arrows in FIG. 1 and FIG. 5 are the directions of air outlet and air inlet.
The supporting grille 14 is a plate-like body, and the maximum width of the cross-section of the supporting grille 14 ranges from 1.5 mm to 3.2 mm.
In some embodiments, the shape of the air inlet 11 is circular and the shape of the water receiving sink 17 is square shaped. The four corners of the water receiving sink 17 are filleted, and the size of the air inlet 11 is matched with the size of the fan wheel of the air conditioner. In some embodiments, referring to FIG. 5, the shape of the air inlet 11 is circular, and the inner diameter of the air inlet 11 gradually decreases along the direction of air inlet (from bottom to top). The structure is beneficial to improving the effect of air inlet and reducing the noise of air inlet. The directions of the arrows in the FIG. 5 are the directions of air inlet and air outlet.
In some embodiments, the air outlet 12 surrounds the four outer sides of the water receiving sink 17, and each outer side is connected to at least one supporting grille 14. The setting ensures the stability of the overall structure of the water pan.
As an example, the air outlet 12 has three bent positions, and two supporting grilles 14 are provided at each bent position. A plane where the supporting grille 14 is located coincides with a center of the air inlet 11.
In some embodiments, the plastic member 10 has a plurality of connecting parts 13, and the connecting part 13 penetrates the foaming member 20. The connecting part 13 may be used to connect the water pan to other components of the air conditioner, and the structural stability of the integral forming of the plastic member 10 and the foaming member 20 may be improved by arranging the connecting part 13 to penetrate the foaming member 20.
For example, the connecting part 13 may be a cylindrical structure, and a center of the connecting part 13 may be provided with a threaded hole, thus the other components of the air conditioning unit may be installed with a water pan through the threaded hole.
In some embodiments, an air guiding ring 15 is formed in the middle of the plastic member 10, the air inlet 11 is defined in a center of the air guiding ring 15, and the air guiding ring 15 and the foaming member 20 do not overlap. The plastic member 10 is an integral structure, and the air guiding ring 15 is a part of the plastic member 10. Therefore, the water pan of embodiments of the present application does not have to install an independent air guiding ring component when in use. In other words, the water pan of embodiments of the present application has the structure of the air guiding ring, and such arrangement makes the fit between the air guiding ring 15 and the fan wheel of the air conditioner more accurate. Since it is not necessary to install the air guiding ring component separately, the production efficiency of the air conditioner is also improved.
For example, an inner surface of the air guiding ring 15 is a circular arc surface or a conical surface. The structure is beneficial to improving air inlet effect of the air inlet 11 and further reducing air inlet noise.
For example, referring to FIG. 5, the shape of the cross-section of the air guiding ring 15 may be a structure of 1/4 circular arc.
In some embodiments, referring to FIG. 7, the air inlet 11 is covered with a protective net 30, and the protective net 30 is detachably connected to the foaming member 20 or the plastic member 10. The protective net 30 may play a protective role, and the protective net 30 may be made of stainless steel. Specifically, the protective net 30 may be connected with the plastic member 10 by a screw or by a snap.
In some embodiments, the protective net 30 may be a grille 30.
In some embodiments, the foaming member 20 is provided with a negative ion generator mounting part configured to mount a negative ion generator 1 and a temperature sensor mounting part configured to mount a temperature sensor 2, and the negative ion generator mounting part is located on a side of the temperature sensor mounting part.
Afloat may also be arranged on the foaming member 20. Since the water pan takes into account the fixed assembly of the float, the negative ion generator 1 and the temperature sensor 2, and has a corresponding structure to take into account the wire routing and fixation, without too much irrelevant structure, the overall volume is small and the material utilization is high in the premise of ensuring the structural strength. The negative ion generator 1 and the temperature sensor 2 are arranged at an edge of the air inlet 11, so that the temperature sensor 2 may detect the temperature, and the negative ion generator 1 may purify the air, conveniently.
The foaming member 20 defines a wire slot 22, and the connecting wire of electronic devices such as the negative ion generator 1, the temperature sensor 2 and the like may pass through the wire slot 22.
In some embodiments, the number of wire slot 22 is two, and the two wire slots 22 are respectively close to two extension ends of the air outlet 12, so that the air outlet 12 is a non-closed annular structure.
Embodiments of the present application further provide an air conditioner, and the air conditioner includes a water pan of any one of the embodiments. The installation of the water pan of the air conditioner is convenient, so that the production efficiency of the air conditioner is improved, and the width of the supporting grille 14 is small, thus air outlet effect is good, and the user experience is improved.

Since the grille 30 and the water pan 40 are snap-fitted, the installation and disassembly of the grille 30 and the water pan 40 are convenient, and then the overhaul and maintenance are convenient. The situation that in the related art a panel may be installed and fixed with the help of manpower to lift the panel is avoided, which reduces the labor load and labor cost of workers, facilitates the alignment of the panel, and improves the installation efficiency. In addition, the situation that in the related art pre-embedded sheet metal parts on the water pan are easy to cause too many parts below the water pan and the production efficiency of the water pan is low is also avoided.

When installing the grille 30, the grille 30 may be rotated, and during rotation, the plurality of first buttons 311 on the body 31 may be clamped with the water pan 40, so that the installation and fixing of the grille 30 and the water pan 40 may be realized. When the grille 30 needs to be disassembled, the grille 30 may be reversely rotated. Thus, the installation and disassembly of the grille 30 are further facilitated.
In some embodiments, the body 31 is provided with a first hole 312, the first hole 312 is adapted for insertion of a first fastener, and the body 31 is detachably connected to the water pan 40 by the first fastener.

Only one first fastener may be provided, and the disassembly of the grille 30 may be achieved by disassembling the first fastener and then unlocking each first button 311, thus avoiding the situation that a plurality of screws needs to be disassembled in the related art, improving the installation and disassembly efficiency of the grille 30, and facilitating the overhaul and maintenance.
In some embodiments, the body 31 is provided with a stiffener 314 which is arranged between adjacent two first buttons 311 and extends along the circumferential direction of the body 31.

In some embodiments, the material of the body 31 is plastic. The plastic material facilitates the injection molding of the grille 30, and since the body 31 is provided with stiffener, the grille 30 still has high structural strength, avoiding the situation that the shape of the body 31 is easy to deform when the plastic is adopted.
