Referring to fig. 1 to 3, the present invention provides a water tray 10 and an indoor unit of an air conditioner including the water tray 10, wherein the water tray 10 has better air tightness to prevent water leakage of the water tray 10.
Referring to fig. 3 to 5, in a first embodiment of the water receiving tray of the present invention, the water receiving tray 10 is a sheet metal part, and the water receiving tray 10 includes a water tray and a water outlet pipe 20; the water tray is provided with a tray bottom 11 and a surrounding wall extending along the periphery of the tray bottom 11, wherein the surrounding wall is provided with a water outlet; the water outlet pipe 20 comprises a first pipe section 21 for connecting with a water outlet pipe, and a second pipe section 22 extending from one end of the first pipe section 21, wherein a limit ring 23 is outwards protruded from the periphery of a pipe orifice of the second pipe section 22, the pipe wall thickness of the second pipe section 22 is smaller than that of the first pipe section 21, and a bulge 221 attached to the periphery of the water outlet is formed on the outer wall surface of the second pipe section 22.
The indoor unit of the air conditioner comprises a shell and an indoor heat exchanger, and the water receiving disc 10 is arranged on the lower side of the indoor heat exchanger and is used for receiving condensed water condensed on the outer wall of the indoor heat exchanger when the indoor heat exchanger works. The outline of the water tray can be round, square or irregular, and the shape and the structural design of the indoor heat exchanger can be specifically referred, so long as the outline of the water tray is matched with the outline of the bottom of the indoor heat exchanger.
The pipe lengths of the first pipe section 21 and the second pipe section 22 are not particularly limited, and the installation stability and the convenience of installation can be ensured. Preferably, the length of the first pipe section 21 is longer than the length of the second pipe section 22 to facilitate connection of the first pipe section 21 to a drain pipe.
Referring to fig. 5 and 6, in the technical solution of the present invention, by providing the stop collar 23 protruding outwards from the periphery of the pipe orifice of the second pipe section 22 of the water outlet pipe 20, and the pipe wall thickness of the second pipe section 22 is smaller than the pipe wall thickness of the first pipe section 21, when the water outlet pipe 20 is installed on the water tray, the first pipe section 21 of the water outlet pipe 20 is first passed through the water outlet from the inner side of the water tray until the stop collar 23 abuts against the inner side of the surrounding wall of the water tray, and then a pair of opposite external forces are applied to the two ends of the water outlet pipe 20, at this time, since the pipe wall thickness of the second pipe section 22 is smaller than the pipe wall thickness of the first pipe section 21, the pipe wall of the second pipe section 22 is first extruded and deformed and bulges outwards, thereby forming a bulge 221, and the bulge 221 is extruded and attached to the surrounding wall of the water outlet, so that the bulge 221 cooperates with the stop collar 23 to fix the water outlet pipe 20 on the water tray, and seal the circumferential gap of the water outlet. Therefore, the water receiving tray of the present invention has better air tightness and can prevent water leakage of the water receiving tray 10, compared with the way of connecting the water receiving tray and the water outlet pipe 20 by welding.
In this embodiment, in order to ensure that the water outlet pipe 20 can be extruded in the axial direction of the water outlet pipe 20, the pipe section of the water outlet pipe 20 located between the first pipe section 21 and the second pipe section 22 is tapered in the direction from the second pipe section 22 to the first pipe section 21 so that a stepped surface 1a facing the orifice of the second pipe section 22 is formed between the first pipe section 21 and the second pipe section 22.
When the water outlet pipe 20 is extruded, a special mould (not shown) which is arranged in a tubular shape is adopted, and the second pipe section 22 of the water outlet pipe 20 is sleeved with the special mould until the inner end of the special mould is abutted with the step surface 1 a; then, the first pipe section 21 of the water outlet pipe 20 passes through the water outlet from the inner side of the water tray, and a pair of opposite external forces are applied to the two ends of the water outlet pipe 20 to squeeze the water outlet pipe 20, so that the water outlet pipe 20 can be accurately positioned in the axial direction, and the water outlet pipe 20 can be ensured to be squeezed along the axial direction of the water outlet pipe 20.
Referring to fig. 5, it is considered that the larger the pipe length of the second pipe section 22 is, the larger the deformation amount thereof is, that is, the larger the ridge 221 is; the smaller the pipe length of the second pipe section 22, the smaller the amount of deformation thereof, i.e., the smaller the ridge 221.
In this embodiment, therefore, to ensure that the second tube segment 22 can be extruded to form the preferred ridge 221, the tube length of the second tube segment 22 (as shown at H in FIG. 5) is in the range of 10mm to 20mm, such as 12mm, 15mm, 18m, or 20mm. If the pipe length of the second pipe section 22 is less than 10mm, the bulge 221 formed by extrusion is small, and the fixing effect and the sealing effect on the water outlet pipe 20 are poor; if the pipe length of the second pipe section 22 is greater than 30mm, the bulge 221 formed by extrusion is large, but the strength of the entire outlet pipe 20 is easily small, and breakage is easily generated.
Referring to fig. 5, in the present embodiment, to strengthen the second pipe section 22 and avoid breakage during extrusion, the thickness of the pipe wall of the second pipe section 22 (e.g. D in fig. 5 2 Shown) is in the range of 1mm to 2mm, for example 1.2mm, 1.4mm, 1.5mm, or 1.8mm. If the wall thickness of the second pipe section 22 is less than 1mm, the wall thickness is too small, the strength is poor, and the deformation easily occurs during the extrusionBreaking; if the wall thickness of the second pipe section 22 is greater than 2mm, the wall thickness is too large, the strength is too strong, and it is difficult to form the ridge 221 by extrusion deformation.
Referring also to fig. 5, in the present embodiment, to enhance the strength of the first pipe section 21 to ensure that the first pipe section 21 is not easily deformed, the pipe wall thickness of the first pipe section 21 (as shown in D in fig. 5 1 Shown) is in the range of 2mm to 4mm, for example 2.5mm, 2.8mm, 3mm, or 3.5mm. If the wall thickness of the first pipe section 21 is less than 2mm, the wall thickness is too small, the strength is poor, and deformation is easy to occur in the extrusion process; if the pipe wall thickness of the second pipe section 22 is greater than 4mm, the second pipe section is strong and is not easy to deform, but the material consumption of the water outlet pipe 20 is correspondingly increased, so that the cost is increased, which is not beneficial to saving the cost.
Preferably, the wall thickness of the second tube section 22 is half the wall thickness of the first tube section 21.
With continued reference to fig. 5, further, to prevent the water outlet pipe 20 from coming out, the height of the stop collar 23 protruding outwards from the outer periphery of the pipe orifice of the first pipe section 21 (as shown by L in fig. 6) is in the range of 2mm to 5mm, such as 2.5mm, 3mm, 3.5mm, or 4mm, 4.5mm, etc.
If the height of the limit ring 23 protruding outwards from the outer periphery of the pipe orifice of the first pipe section 21 is smaller than 2mm, the area of the abutting surface between the limit ring 23 and the surrounding wall on the circumferential direction of the water outlet is smaller, and the limit ring 23 is easy to separate outwards from the water outlet; if the height of the limit ring 23 protruding outwards from the outer periphery of the pipe orifice of the first pipe section 21 is greater than 5mm, the area of the abutting surface between the limit ring 23 and the surrounding wall on the circumferential direction of the water outlet is large, the limit ring 23 is difficult to separate outwards from the water outlet, but the material consumption of the water outlet pipe 20 is correspondingly increased, so that the cost is increased, and the cost is not saved.
Preferably, the height of the stop collar 23 protruding outward from the outer periphery of the orifice of the first pipe section 21 is greater than or equal to the pipe wall thickness of the first pipe section 21.
Based on the above embodiment, considering that the water tray is a sheet metal member, rust corrosion is likely to occur due to long-term infiltration with water, in this embodiment, a rust-preventing coating is provided on the outer surface of the water tray.
In this embodiment, because the temperature of the condensed water is low, the difference between the inner temperature and the outer temperature of the water tray is large, condensed water is easily formed on the outer surface of the water tray, and in order to avoid this, heat insulation cotton (not shown) is arranged on the outer surface of the water tray.
Referring to fig. 2 and 3, considering that the drip tray 10 is generally required to accommodate both a floor air conditioner and a floor air conditioner, the drip tray generally has a main tray and side trays, with the side trays standing upright from the main tray. If the water receiving tray is installed in the horizontal air conditioner, the main tray receives condensed water, and if the water receiving tray is installed in the vertical air conditioner, the side tray receives condensed water. The common treatment method in the prior art is to draw and shape the main disc firstly, then open the notch on the side wall of the two sides of the water-receiving disc corresponding to the bending position, weld the notch after bending, and form the L-shaped water-receiving disc. In the forming mode water pan, the sheet metal part is required to be cut and then welded, however, on one hand, tiny air holes can exist at the welding position; on the other hand, after welding for a period of time, the weld joint generates tiny holes due to stress release or corrosion, and water leakage of the water receiving disc can be caused in both aspects.
Referring to fig. 2, 3 and 7, in a second embodiment of the water pan according to the present invention, the difference is that the pan bottom 11 includes a first bottom plate 111 and a second bottom plate 112 disposed at an angle; the enclosure walls comprise a first enclosure wall 113 distributed on the first base plate 111, a second enclosure wall 114 separately arranged on the second base plate 112, and a connecting section 115 connecting the first enclosure wall 113 and the second enclosure wall 114, wherein the first enclosure wall 113, the second enclosure wall 114 and the connecting section 115 are integrally arranged.
Specifically, the first bottom plate 111 and the second bottom plate 112 are substantially L-shaped. The connection section 115 is used to connect the first and second enclosing walls 113 and 114, thereby preventing water leakage at the connection of the first and second enclosing walls 113 and 114.
Here, the connection section 115 is integrally formed with the first surrounding wall 113 and the second surrounding wall 114, that is, before forming, the connection section 115, the first surrounding wall 113 and the second surrounding wall 114 are a flat plate, and after bending the flat plate, the bending part is subjected to extrusion force to be folded outwards, so as to form the connection section 115. Thus, no air holes are generated between the first surrounding wall 113 and the second surrounding wall 114 due to welding, and condensed water in the water receiving disc 10 does not ooze out from the joint.
In this embodiment, a connecting section 115 is formed between the first surrounding wall 113 and the second surrounding wall 114 by bending, so that the physical continuity of the first surrounding wall 113 and the second surrounding wall 114 is not damaged, and the conventional welding process is omitted, thereby avoiding the risk of water leakage caused by welding seams to the water receiving tray 10.
Referring to fig. 7 and 8, in the above embodiment, the connection section 115 may be bent inward or outward. In view of the fact that the inward bending of the connection section 115 is inconvenient for handling and shaping, in this embodiment, the connection section 115 is provided in an outward bending.
Referring to fig. 1 to 5, when the water pan 10 is installed in a horizontal air conditioner, the first bottom plate 111 serves as a water receiving surface; when the drip tray 10 is mounted to the floor type air conditioner, the second bottom plate 112 serves as a water receiving surface. The installation position of the water pan 10 in the vertical air conditioner is rotated by 90 ° relative to the installation position in the horizontal air conditioner, so that in order to keep the water pan 10 from being inclined when being installed, any water pan 10 is not inclined to cause the overflow of condensed water, the included angle between the first bottom plate 111 and the second bottom plate 112 is set to be approximately 90 °, and in this embodiment, the included angle is in the range of 85 ° to 105 °, for example 87 °, 90 ° or 93 °.
Referring to fig. 5 and 8, when the first wall 113 and the second wall 114 are creased, an intersection line is necessarily formed on the first wall 113, and an intersection line is also formed on the second wall 114. Here, the boundary line extends obliquely from the connection between the first peripheral wall 113 and the first bottom plate 111 in a direction away from the first bottom plate 111, so that the boundary line forms an angle α with the first bottom plate 111, which if too small, may result in a low position of the crease seam 1150 of the connection section 115, and condensed water in the water pan 10 may overflow from the crease seam 1150. If the angle α is too large, this necessarily results in a smaller angle β (α+β=90°) between the other boundary line and the second base plate 112, which also results in a lower height of the crimp seam 1150 relative to the second base plate 112, and may also result in condensate overflowing from the end 1150 of the connecting segment 115 facing away from the chassis 11. Thus, in this embodiment, the intersection line of the connecting section 115 and the first peripheral wall 113 forms an angle with the first bottom plate 111 of between 40 ° and 50 °, and the connection between the connecting section 115 and the second peripheral wall 114 forms an angle with the second bottom plate 112 of between 40 ° and 50 °.
Referring to fig. 7 and 8, the connecting section 115 may have various shapes, such as a cone shape, a triangle shape attached to the first and second surrounding walls 113 and 114, and a plate shape extending from the plane of the first and second surrounding walls 113 and 114. In this embodiment, in order to increase the strength of the water pan 10, the connecting section 115 is arranged in a triangle shape and is attached to the first surrounding wall 113 or/and the second surrounding wall 114. Here, the first wall 113 and the second wall 114 need to be separated against the large deformation force of the connection section 115, so that the strength of the water receiving tray 10 is greatly enhanced.
Referring to fig. 7, the water in the water receiving tray 10 needs to be drained in time, and the number of the water outlets is plural, wherein a first water outlet 1110 is provided on a first enclosure wall 113 of the water receiving tray 10, and then the water outlet is connected through a drain pipe, and the accumulated water in the water receiving tray 10 can be drained in time through the drain pipe after reaching a certain height. Here, in order to prevent the water in the drip tray 10 from overflowing from the connection section 115, the end 1150 of the connection section 115 remote from the bottom plate 11 has a height greater than the height of the first water outlet 1110 with respect to the first bottom plate 111. Likewise, the second enclosure wall 114 has a second water outlet 1120 therein, and an end 1150 of the connecting section 115 remote from the chassis 11 has a height relative to the second floor 112 that is greater than the height of the second water outlet 1120. As such, no matter the drip tray 10 is installed in a horizontal air conditioner or a vertical air conditioner, the condensed water in the drip tray 10 is difficult to overflow from the end 1150 of the connection section 115, which is far from the chassis 11.
Referring to fig. 7, it is considered that the connection strength of the connection section 115 to the first and second peripheral walls 113 and 114 is weak because the relative positional relationship between the first and second bottom plates 111 and 112 may be changed if the first and second peripheral walls 113 and 114 are subjected to a large pulling force or the drip tray 10 is used for a long time. In one embodiment, to further strengthen the connection between the first base plate 111 and the second base plate 112, the first surrounding wall 113 and the second surrounding wall 114 are also fixedly connected by a reinforcing connection. The fixing and reinforcing connector may be a rivet, or may be a clasp or a clasp groove provided separately on the first wall 113 and the second wall 114.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
