Referring to fig. 1 to 3, according to an embodiment of the present application, there is provided a water-receiving tray, which includes a water-receiving tray body 10, a water-blocking structure 20, and a sealing structure 30.
Wherein, the water pan body 10 is provided with a containing cavity and a water outlet 13; the water retaining structure 20 is arranged in the water pan body 10, the water retaining structure 20 divides the accommodating cavity into a first cavity 11 and a second cavity 12, and the water outlet 13 is communicated with the first cavity 11; a sealing structure 30 is provided within the second chamber 12.
In the present embodiment, the second chamber 12 on the water receiving tray body 10 is used for receiving water, and in the actual use process, after the condensed water in the second chamber 12 reaches a certain level, the sealing structure 30 floats up, and after the water level of the condensed water in the second chamber 12 is higher than the water retaining structure 20, the water in the second chamber 12 flows into the first chamber 11 from the water retaining structure 20, and is discharged from the water outlet 13 through the drain pipe.
Because the sealing structure 30 is arranged on the second chamber 12 in the embodiment, the water surface in the second chamber 12 can be isolated from oxygen as much as possible through the effect of the sealing structure 30, and the effect of inhibiting the growth of mould is further achieved, so that the drain pipe connected with the water receiving disc is prevented from being blocked, and the water leakage phenomenon of the air conditioner is prevented.
In order to facilitate water receiving, the sealing structure 30 in this embodiment is provided with a water leakage hole 31, and a second gap (not shown in the figure) is provided between the sealing structure 30 and the second chamber 12, and the width of the second gap is 4mm to 6mm, so that, when in use, condensed water of the air conditioner enters the second chamber 12 from the water leakage hole 31 on the sealing structure 30 and the gap between the sealing structure 30 and the second chamber 12, and the air conditioner has a simple structure and is convenient to process.
Preferably, the sealing structure 30 in the present embodiment is a sealing plate or the like, however, in other embodiments of the present application, the sealing structure 30 may be a sealing cover or the like, and any other modification forms within the scope of the present application are possible.
The number of the water leakage holes 31 in the present embodiment is 4 to 6, for example 5, and the aperture of the water leakage holes 31 is Φ18mm to Φ22mm, for example Φ20mm, so that the condensed water can leak into the second chamber 12.
Referring to fig. 1 to 3 again, the water blocking structure 20 in this embodiment is a water blocking rib that divides the accommodating cavity into the first cavity 11 and the second cavity 12, and has a simple structure and is convenient for processing.
In the actual processing process, when the sealing structure 30 is installed in the second chamber 12 and is at the initial position, that is, when no condensed water exists in the water receiving disc, the upper surface of the sealing structure 30 is lower than the upper surface of the water retaining structure 20, and in the actual use, the sealing structure 30 can float up and down in the second chamber 12 along with the change of the water level in the second chamber 12, so that the sealing structure 30 can be contacted with the water surface in the second chamber 12 as much as possible, the condensed water in the second chamber 12 is prevented from being contacted with oxygen, and the growth of mold is further inhibited.
The first gap 14 is arranged between the sealing structure 30 and the water retaining structure 20, and condensed water in the second chamber 12 is convenient to flow to the first chamber 11 through the action of the first gap 14. Preferably, the width of the first gap 14 is 18mm to 22mm, for example 20mm, which on the one hand effectively prevents the water in the first chamber 11 from coming into contact with oxygen and on the other hand also facilitates the flow of condensed water in the second chamber 12 into the first chamber 11 for draining.
The second chamber 12 in this embodiment is provided with a supporting structure 121, and the sealing structure 30 is supported in the second chamber 12 by the supporting structure 121, so as to prevent the sealing structure 30 from falling into the bottom of the second chamber 12.
Preferably, the support structure 121 in this embodiment is a rib-like step provided on the inner wall surface of the second chamber 12. The rib-like steps are plural, and the plural rib-like steps are arranged at intervals along the inner wall surface of the second chamber 12 so as to support the seal structure 30, and the rib-like steps are 8mm to 12mm, for example, 10mm.
Preferably, the volume of the first chamber 11 is smaller than the volume of the second chamber 12, so as to collect more condensed water, and the water outlet 13 is positioned at the bottom of the first chamber 11, so as to drain the water in the first chamber 11 as much as possible.
Mold growth is three elements: high humidity, about 25 deg.c, oxygen. Both of the former can be satisfied and cannot be changed in the condensed water of the water receiving disc of the air conditioner. According to the embodiment, the sealing plate is added on the water receiving disc, the sealing plate is in contact with the water surface, and the water surface of the water receiving disc is isolated from oxygen by about 95% of the area. The effect of inhibiting the growth of mould is achieved. The water leakage fault of the air conditioner caused by the blockage of the drain pipe by mould can be effectively reduced. In operation, condensed water on the evaporator flows into the second chamber 12 through the water leakage holes 31 on the sealing plate and the space between the sealing plate and the water receiving disc. The condensed water is discharged from the drain pipe through the overflow water inlet and outlet 13 after exceeding the height of the water retaining rib.
The second chamber 12 of the water pan of the application is internally provided with 5 rib steps with the height of 10mm, so as to prevent the sealing plate from descending to the bottom of the second chamber 12. The interval between the sealing plate and the water retaining ribs is 20mm, and 5 water leakage holes 31 with phi of 20mm are formed in the sealing plate. The interval between closing plate and the inner wall surface of second cavity 12 is 5mm, through increasing the closing plate on the water collector, and the closing plate contacts with the surface of water, and the surface of water collector has nearly 95% area and oxygen to isolate, reaches the effect of restraining mould growth.
According to another aspect of the present application, there is also provided an air conditioner including a water tray, which is the water tray in the above embodiment.
From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects: the application can prevent mold from growing in the water pan of the air conditioner and effectively reduce the problem of water leakage caused by mold blocking the drain pipe.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
