Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification equipment, in particular to a water receiving tray component and a dehumidification unit. Background Art

[0002] A three-in-one dehumidifier is primarily divided into five sections: the compressor section, return air section, fresh exhaust section, fin section, and supply air section. During the dehumidification process, the fin section generates a large amount of condensed water due to heat exchange in the heat exchanger. If this condensed water is not promptly discharged, it can severely impact the unit's normal operation and even corrode components within the unit, shortening the dehumidifier's service life. Therefore, to quickly drain the condensed water, dehumidifiers typically incorporate a water pan at the bottom of the heat exchanger. However, external piping connected to the heat exchanger also generates condensed water, which, if dripped directly into the unit, can also pose a risk to the unit's operational stability.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0041] In the description of this utility model, it should be noted that the terms "vertical," "upper," "lower," and "horizontal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0043] A three-in-one dehumidifier is primarily comprised of five sections: the compressor section, the return air section, the fresh exhaust section, the fin section, and the supply air section. During the dehumidification process, the fin section generates a large amount of condensed water due to heat exchange in the heat exchanger. If this condensed water is not promptly discharged, it can severely impact the unit's normal operation and even corrode components within the unit, shortening the dehumidifier's service life. Therefore, to quickly drain the condensed water, dehumidifiers typically incorporate a water pan at the bottom of the heat exchanger. However, external piping connected to the heat exchanger also generates condensed water, which, if directly dripped into the unit, can also pose a risk to the unit's operational stability.

[0044] To address this issue, the current approach is to design a water trough with an opening that completely covers the heat exchanger body and external piping. This allows all condensed water from the heat exchanger body and external piping to fall directly into the trough, which is then drained to the outside of the unit through a drain pipe. However, this arrangement requires a large opening in the trough, and if multiple components are welded or assembled, water leakage is likely to occur at the welds or joints, posing a safety hazard.

[0045] Based on this, an embodiment of the present application provides a water receiving pan assembly, in which a water receiving trough is arranged below the heat exchanger body with a large amount of condensed water, and a side water receiving pan is arranged below the external pipeline to receive the condensed water from the external pipeline. The condensed water collected by the side water receiving pan is then introduced into the water receiving trough through a connecting piece, and then discharged to the outside of the unit through the water receiving trough as a whole. In this way, the overall size of the water receiving trough is reduced, and at the same time, water seepage caused by gaps caused by connections or welding is avoided, so as to improve the operating stability of the dehumidification unit.

[0046] See also Figure 1-8 , this embodiment provides a water receiving pan assembly for discharging condensed water from a heat exchanger. Specifically, the heat exchanger includes a heat exchanger body and an external refrigerant pipeline. The water receiving pan assembly includes a main water receiving pan 10, side water receiving pans 20 provided on both sides of the main water receiving pan 10, and a connector 30 connecting the main water receiving pan 10 and the side water receiving pan 20. Specifically, the main water receiving pan 10 is provided with a water receiving trough 11 for collecting condensed water. The heat exchanger body is provided above the water receiving trough 11, and its orthographic projection on the water receiving trough 11 is completely located inside the water receiving trough 11, so as to ensure that the condensed water of the heat exchanger body can all fall into the water receiving trough 11, thereby avoiding leakage of condensed water and causing safety hazards.

[0047] See also Figure 3-6Specifically, the side water tray 20 is located below the external refrigerant pipeline to collect condensed water from the external refrigerant pipeline. The connector 30 has a stepped structure, which includes a first abutting portion 31 and a second abutting portion 32. The first abutting portion 31 abuts the bottom of the side water tray 20 to support it; the end of the second abutting portion 32, away from the side water tray 20, covers the top of the water receiving trough 11. The height of the first abutting portion 31 is greater than the height of the second abutting portion 32, so that the condensed water from the side water tray 20 can flow into the second abutting portion 32 and then fall into the water receiving trough 11.

[0048] See also Figure 1 and Figure 2 It can be understood that the side wall of the water receiving trough 11 is provided with a drain hole 112 for discharging water, and the drain hole 112 is externally connected to a drain pipe 113 for draining water. In the setting mode of the embodiment of the present application, the drain hole 112 is provided on the side wall of the water receiving trough 11 near the side water receiving pan 20, and the drain pipe 113 connected to the drain hole 112 is provided below the side water receiving pan 20. Compared with the setting mode of the traditional large-sized water receiving trough 11 with an external drain pipe 113, the water receiving pan assembly provided in the embodiment of the present application rationally utilizes the space below the side water receiving pan 20 to set the drain pipe 113, and the overall space occupied by the water receiving pan assembly is smaller; and, by diverting the condensed water from the side water receiving pan 20 to the water receiving trough 11 through the connector 30, the purpose of completely collecting the condensed water from the heat exchanger body and the external refrigerant pipeline can also be achieved without the risk of water leakage.

[0049] See also Figure 6 Furthermore, in some embodiments, a guide portion 21 is provided at the end of the side drain pan 20 near the main drain pan 10. This guide portion 21 extends obliquely toward the second abutment portion 32 to facilitate diversion of condensed water from the side drain pan 20 to the second abutment portion 32. Specifically, a first angle greater than 90 degrees and less than 180 degrees is formed between the guide portion 21 and the bottom of the side drain pan 20. Preferably, this first angle is 135 degrees.

[0050] Furthermore, in some embodiments, the bottom of the side water tray 20 is tilted at a certain angle toward one side of the guide portion 21 to form a guide surface with a certain slope. This is more conducive to the condensed water in the side water tray 20 to flow quickly into the water receiving trough 11, avoiding the condensed water from accumulating in the side water tray 20 and causing ice.

[0051] See also Figure 3-6Furthermore, in some embodiments, the connector 30 further includes a connecting portion 33 disposed between the first abutting portion 31 and the second abutting portion 32. The connecting portion 33 is tilted and forms a second angle greater than 90 degrees with the first ground connection portion and the second abutting portion 32, respectively, to prevent water leakage from the side water tray 20. Preferably, in this embodiment, the first angle is equal to the second angle, and the guide portion 21 is disposed parallel to and above the connecting portion 33.

[0052] See also Figure 5 and Figure 6 Furthermore, in some embodiments, a first flange 111 bent toward the inner side of the main water receiving tray 10 is provided on the side wall of the main water receiving tray 10 near the side water receiving tray 20; one end of the second abutting portion 32 abuts against the first flange 111, and the second abutting portion 32 is supported by the first flange 111, and the other end thereof protrudes from the first flange 111 and is provided with a plurality of heat exchanger mounting holes 321 for mounting the heat exchanger main body; the heat exchanger mounting holes 321 are provided above the water receiving trough 11, and the condensed water leaking through the heat exchanger mounting holes 321 can directly fall into the water receiving trough 11, so that the problem of water leakage in the traditional heat exchanger mounting holes 321 can be overcome.

[0053] See also Figure 2 and Figure 5-8 Furthermore, the main water tray 10 also includes a support base 12 disposed within the water receiving trough 11 for supporting the heat exchanger. Specifically, the support base 12 includes at least one transverse support member 121. The transverse support member 121 is inserted into the water receiving trough 11, with its end abutting against the first flange 111 to support the second abutting portion 32 abutting against the first flange 111, and the heat exchanger body fixedly connected to the second abutting portion 32. It is understood that the transverse support member 121 can be single or multiple, spaced apart.

[0054] Furthermore, the support base 12 also includes at least one longitudinal support member 122, which is also inserted into the water receiving trough 11 and arranged in an interlaced manner with the transverse support members 121 to support the heat exchanger body. Preferably, in this embodiment, the transverse support members 121 are vertically fixed inside the longitudinal support members 122. The longitudinal support members 122 ensure that the transverse support members 121 do not tilt or deform, thereby preventing the transverse support members 121 from affecting the installation stability of the heat exchanger body. In this embodiment, the top of the longitudinal support member 122 protrudes beyond the transverse support member 121 to abut against the middle of the heat exchanger body, further supporting the heat exchanger body and ensuring its stability. In this embodiment, the transverse support member 121 and the longitudinal support member 122 are both sheet metal structures, wherein the longitudinal support member 122 is in an inverted U shape, and its end portion abutting against the bottom of the water receiving trough 11 is bent and extended relatively inward to increase the contact area with the bottom of the water receiving trough 11, thereby avoiding the bottom of the water receiving trough 11 from being squeezed by pressure and deformed or cracked, which may cause hidden dangers of water leakage.

[0055] Furthermore, in some embodiments, the transverse support member 121 and / or the longitudinal support member 12 is provided with a water hole 123 , so that the condensed water can flow in the water receiving trough 11 .

[0056] Furthermore, in some embodiments, the water receiving tray assembly further includes a bottom tray 50 and a heat preservation member 40 provided between the bottom tray 50 and the main water receiving tray 10. The bottom tray 50 is used to support the main water receiving tray 10 and the side water receiving tray 20, and the heat preservation member 40 is used to prevent condensation on the sheet metal of the main water receiving tray 10.

[0057] See also Figure 3-5 Specifically, the connector 30 also includes a first fixing portion 34 and a second fixing portion 35, located at an end distal from the second abutting portion 32. The first fixing portion 34 extends along the bottom of the main water tray 10, toward the inside of the main water tray 10. The first fixing portion 34 and the second abutting portion 32 enclose a U-shaped receiving space 36, with the two ends of the main water tray 10 fixedly inserted into the receiving spaces 36 on either side. The second fixing portion 35 extends in the opposite direction of the first fixing portion 34, that is, toward the outside of the main water tray 10, and is removably connected to the base plate 50. This avoids water seepage caused by the gap created by directly fixing the main water tray 10 to the base plate. Furthermore, in this embodiment, the drain pipe 113 is configured as a straight-through internal thread. When the main water tray 10 needs to be replaced, the drain pipe 113 does not need to be removed beforehand; the connector 30 can be simply removed from the end of the main water tray 10 to replace the main water tray 10, further simplifying the assembly and disassembly process.

[0058] See also Figure 5-8In this embodiment, the second fixing portion 35 is locked to the chassis 50 via a locking member. If the main water tray 10 rusts and becomes perforated due to prolonged water exposure, it may be necessary to remove the main water tray 10 for replacement. In this case, simply lift the heat exchanger and remove the locking member to remove the main water tray 10 from the chassis 50 for replacement, providing convenient assembly and disassembly and enhanced applicability. It is understood that the second fixing member may also be connected to the chassis 50 via other detachable connection methods to achieve a detachable connection between the main water tray 10 and the chassis 50, facilitating routine maintenance.

[0059] Furthermore, in some embodiments, the chassis 50 is provided with a first frame 51, the first frame 51 includes a plurality of spaced-apart beams 512, the main water receiving tray 10 is fixed to the beams 512 by the second fixing portion 35, and the weight of the main water receiving tray 10 and the heat exchanger provided above the main water receiving tray 10 is supported by the beams 512.

[0060] Preferably, the heat-insulating member 40 is sandwiched between two adjacent beams 512 and attached to the bottom of the main water receiving tray 10 .

[0061] Specifically, the cross beam 512 is a "J"-shaped structure with flanges at the ends, and the thermal insulation component 40 is clamped in the space enclosed by two adjacent flanges of the two adjacent cross beams 512. During assembly, the thermal insulation component 40 only needs to be placed between the two adjacent cross beams 512, and the assembly method is simple.

[0062] Preferably, the insulation component 40 is a foam board. Compared with the traditional insulation sponge which loses its insulation effect due to insufficient viscosity and falling off after long-term use, the foam board used in the embodiment of the present application has a longer service life than the insulation sponge and higher stability of the unit.

[0063] Furthermore, the first frame 51 further includes an end plate 511 arranged around the outer periphery of the cross beam 512 . A through hole 5111 is provided on the end plate 511 close to the side water tray 20 for connecting the drain pipe 113 .

[0064] Furthermore, in some embodiments, the base 50 further includes a second frame 52 stacked above the first frame 51. The outer periphery of the assembly formed by the main water receiving tray 10, the connector 30, and the side water receiving tray 20 is fixedly connected to the second frame 52. Specifically, the edge of the second frame 52 is provided with a second flange 521 that is bent inward. The main water receiving tray 10, the connector 30, and the side water receiving tray 20 are each provided with a hanging ear 22 corresponding to the second flange 521. By fixing the hanging ear 22 to the second flange 521, the main water receiving tray 10, the connector 30, and the side water receiving tray 20 are supported by the second flange 521.

[0065] An embodiment of the present application also provides a dehumidification unit, which is provided with a heat exchanger and a water collecting pan assembly. The water collecting pan assembly is arranged below the heat exchanger, and is used to collect condensed water from the heat exchanger body and the external refrigerant pipeline, and discharge the condensed water to the outside of the unit through a drain pipe to prevent the condensed water from affecting the stable operation of the unit.

[0066] Compared with the prior art, the beneficial effects of the embodiments of the present application are:

[0067] (1) A main water pan and a side water pan are respectively set for the heat exchanger body and the external refrigerant pipeline to collect condensed water to prevent the condensed water from the external refrigerant pipeline from leaking into the unit and affecting the stable operation of the unit;

[0068] (2) By providing a connector with a step structure to connect the main water receiving tray and the side water receiving tray, the condensed water in the side water receiving tray is diverted to the water receiving trough of the main water receiving tray and discharged to the outside of the unit through the drain pipe. In this way, the size of the water receiving trough can be reduced;

[0069] (3) The main water tray is fixed to the chassis by a connector, which can avoid the main water tray being directly fixed to the chassis to form a connection gap and thus cause water leakage;

[0070] (4) The connecting member is provided with a second fixing portion extending toward the outside of the main water receiving tray. By detachably connecting the second fixing portion to the chassis, the main water receiving tray can be disassembled, assembled, and replaced.

[0071] (5) The insulation effect is improved by using foam boards instead of traditional insulation sponges to avoid condensation in the main water receiving tray; at the same time, the foam boards are clamped between the cross beams set on the chassis to achieve simple assembly and simplify the assembly process.

[0072] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
