Description
Technical Field
The application relates to the technical field of machine room air conditioners, in particular to a water receiving component applied to an inter-column air conditioner and the inter-column air conditioner comprising the water receiving component.
Background
The inter-column air conditioner is applied to the indoor side, and indoor return air with high temperature is changed into indoor air outlet with low temperature through heat exchange of the evaporator, so that the machine room is cooled. When the temperature of the evaporator fins is lower than the saturated dew point temperature in the air, water vapor in the air can be condensed and accumulated at the evaporator fins to generate condensed water, and when the condensed water is accumulated to a certain amount, water drops can be formed under the action of gravity and flow downwards along the fins. Because the air conditioner between the columns usually needs to run for a long time and can continuously generate condensed water, a water receiving tray is generally additionally arranged below the evaporator and is used for receiving and storing water flowing down from the fins of the evaporator, so that the water is ensured not to flow to other parts of the air conditioner and the outside of the air conditioner between the columns, and potential safety hazards are further prevented.
However, in the conventional water receiving structure of the inter-column air conditioner, a sealed cold and hot channel needs to be established between the evaporator end plate and the water receiving disc so as to prevent air flow short circuit. When the water outlet is positioned on the return air side of the evaporator, the condensed water of the water receiving tray on the air outlet side of the evaporator cannot smoothly flow to the water outlet positioned on the return air side of the evaporator. When the water drain is positioned at the air outlet side of the evaporator, the condensed water of the water receiving disc at the air return side of the evaporator cannot smoothly flow to the water drain at the air outlet side, if the condensed water of the water receiving disc cannot be smoothly discharged, overflow can occur when the condensed water is gathered to a certain water level, and the water drain is inconvenient to maintain.

Referring to fig. 1 and 2, fig. 1 is a perspective view of a water receiving assembly according to an embodiment of the present application, and fig. 2 is a perspective exploded view of a water receiving assembly according to an embodiment of the present application. The water receiving assembly 100 is applied to an inter-row air conditioner, and the inter-row air conditioner comprises an evaporator 200, and the water receiving assembly is received at the bottom of the evaporator when the water receiving assembly is applied to the air conditioner. The water receiving assembly 100 comprises a water receiving disc 1, a flow guiding piece 2 and a water outlet maintenance cover plate 3, wherein the water receiving disc 1 is provided with a first accommodating groove 10, the first accommodating groove 10 is used for collecting condensed water, and a water outlet is formed in the bottom wall 11 of the first accommodating groove 10. The flow guiding piece 2 is arranged in the first accommodating groove 10 and is enclosed with the water receiving disc 1 to form a first cavity 300, the first cavity 300 is provided with a first liquid through port 21 and a second liquid through port 22, so that the first liquid through port 21, the second liquid through port 22 and the water outlet are sequentially communicated to form a channel for condensate water to flow, and at least part of condensate water in the first accommodating groove 10 can be sequentially discharged out of the water receiving disc 1 through the first liquid through port 21, the first cavity 300, the second liquid through port 22 and the water outlet. The drain port maintenance cover plate 3 is connected to the water pan 1 and covers the drain port to form a second cavity 400 (shown in fig. 3), and the drain port maintenance cover plate 3 is provided with a third liquid port 31, so that the third liquid port 31, the second cavity 400 and the drain port are sequentially communicated to form a channel for condensate water to flow, and at least part of condensate water in the first accommodating groove 10 can be sequentially discharged out of the water pan 1 through the third liquid port 31, the second cavity 400 and the drain port.
When the water receiving assembly 100 is installed in an inter-row air conditioner, the first liquid inlet 21 and the second liquid inlet 22 are respectively located at two sides (air outlet side and air return side) of the evaporator, when the fan drives air to flow through the evaporator, the first liquid inlet 21, the first cavity 300, the second liquid inlet 22 and the water outlet are communicated to form a channel for flowing condensed water in a negative pressure area (the negative pressure area is an area with air pressure lower than the existing atmospheric pressure), and the third liquid inlet 31, the second cavity 400 and the water outlet are communicated to form a channel for flowing condensed water in the negative pressure area. When the evaporator generates condensed water, part of the condensed water flows to the water receiving disc 1 along the outer surface of the flow guide piece 2 under the action of self gravity, flows to the water outlet through the first liquid through hole 21, the first cavity 300 and the second liquid through hole 22 in sequence, and is discharged out of the water receiving disc 1 through the water outlet; part of the condensed water flows to the water receiving disc 1 along the outer surface of the flow guiding piece 2 under the action of gravity, flows to the water outlet through the third liquid outlet 31 and the second cavity 400, and is discharged out of the water receiving disc 1 through the water outlet.
When the water receiving assembly 100 is installed in an inter-column air conditioner, the first liquid inlet 21 may be located at the air outlet side of the evaporator 200, and the second liquid inlet 22 and the water outlet may be located at the air return side of the evaporator 200; the first liquid inlet 21 may be located on the return air side of the evaporator 200, and the second liquid inlet 22 and the water outlet may be located on the outlet air side of the evaporator 200. Referring to fig. 3, fig. 3 is a cross-sectional view of a water receiving assembly and an evaporator according to an embodiment of the present application, and in this embodiment, when the water receiving assembly 100 is installed in an inter-row air conditioner, a first liquid through hole 21 is located on an air outlet side of the evaporator 200, and a second liquid through hole 22 and a water outlet are located on a return air side of the evaporator 200. When the fins on the air outlet side of the evaporator generate condensed water, the condensed water flows to the water receiving disc 1 along the outer surface of the flow guide piece 2 under the action of self gravity, flows to the water outlet through the first liquid through hole 21, the first cavity 300 and the second liquid through hole 22 in sequence, and is discharged through the water outlet; when the fins on the return air side of the evaporator generate condensed water, the condensed water flows to the water receiving disc 1 along the outer surface of the flow guide member 2 under the action of self gravity, flows to the water outlet through the third liquid outlet 31 and is discharged from the water outlet.
When the inter-column air conditioner provided with the water receiving component works, as the first liquid through port 21, the first cavity 300, the second liquid through port 22 and the water outlet are communicated to form a channel for condensate water flow in a negative pressure area, the third liquid through port 31, the second cavity 400 and the water outlet form a channel for condensate water flow in the negative pressure area, so that condensate water generated by the evaporator flows in the channel, the flowing resistance of the condensate water in the water receiving disc 1 is reduced, and the condensate water in the whole water receiving disc 1 can smoothly flow out of the water receiving disc 1 through the water outlet. Meanwhile, because the area where the water outlet is located is at the atmospheric negative pressure, the condensed water can generate bubbling phenomenon at the water outlet under the influence of the atmospheric pressure when flowing outside the air conditioner through the water outlet pipe, the water outlet is covered by the water outlet maintenance cover plate 3 in the embodiment, so that the splashing of the condensed water at the water outlet is prevented, and the water outlet maintenance cover plate 3 can be detached when the water outlet is not smooth or blocked, so that the water outlet is maintained.
In this embodiment, the bottom wall of the water pan 1 is provided with not only the gravity drain 101 but also the water pump drain 102, and the condensed water can be drained from the gravity drain 101 by the gravity of the condensed water or can be drained from the water pump drain 102 by the action of the water pump. It will be appreciated that in other implementations, only one drain may be provided, from which condensate may drain under its own weight and action, or from which condensate may drain under the action of a water pump.
Further, the drain port maintenance cover plate 3 is used for circulating condensed water except for the opened third liquid port 31, and the other parts are used for completely covering the drain port, so that a negative pressure area is formed between the operation of the inter-column air conditioner and the water receiving disc 1, the turbulence condition of air flow on the condensed water in the first liquid circulating channel is further reduced, the bubbling splash condition of the drain port at the position when the drain port is connected to the atmospheric positive pressure outside the air conditioner through a drain pipe is avoided, and the negative pressure area can be constructed by other sheet metal structures or other materials or structural forms.
With continued reference to fig. 2, the water-receiving tray 1 includes a bottom wall 11 and a side wall 12, and the side wall 12 is disposed around the bottom wall 11 to form a first receiving groove 10. The flow guiding piece 2 comprises a cover plate 23 and a folded edge 24, and the folded edge 24 is arranged around the periphery of the cover plate 23 to form a second accommodating cavity. During assembly, the guide member 2 is disposed in the first accommodating groove 10, so that the folded edge 24 of the guide member 2 is connected with the bottom wall 11 of the water pan 1, and the cover plate 23, the folded edge 24 and the bottom wall of the first accommodating groove 10 enclose to form a first cavity 300, and the first liquid through hole 21 and the second liquid through hole 22 are formed in two folded edges 24 opposite to each other of the guide member 2.
According to the application, the positive pressure on the return air side of the evaporator and the negative pressure on the air outlet side of the evaporator are separated by the cavity formed by the flow guide piece and the water receiving disc, so that the condensate water in the water receiving disc 1 can be smoothly discharged when the condensate water reserves are large, and the interference of the positive pressure airflow on the return air side of the evaporator on the circulation of the condensate water is reduced. Meanwhile, the guide piece 2 can extend to the bottom wall 11 of the water receiving disc 1 through the folded edge 24, so that condensed water can smoothly flow into the water receiving disc 1 through the folded edge 24, and the conditions of flow interruption and water drop hanging on the guide piece 2 caused by air flow turbulence are avoided.
Further, the water receiving assembly 100 further includes a water blocking member 4, and the water blocking member 4 is connected to the cover plate 23 and located at an upper portion of the first liquid through hole 21. Because the minimum part of air flow flows through the channels formed by the first liquid through hole 21, the first cavity 300, the second liquid through hole 22 and the water outlet, the application prevents the condensate water flowing to the flow guiding piece 2 on the evaporator fin from being split to flow down the water receiving disc 1 from the first liquid through hole 21 by the arrangement of the water blocking piece 4, so that water drops hang and water flow hang, and the water blowing condition occurs at the first liquid through hole 21. In this embodiment, the water deflector 4 is formed by bending the folded edge 24 upwards, and the folded edge 24 is bent upwards to form the water deflector 4, so that no additional material is required, and the product cost is reduced. It will be appreciated that in other embodiments, the water deflector 4 may be a separate component, with the cover plate 23 being attached by welding.
Based on the principle of the interaction relation of the gravity of the fluid and the condensate water and the air flow interference resistance and the practical experiment, the gap ratio of the liquid flow channel is obtained, namely, the ratio of the sectional area of the first liquid flow port 21 for the condensate water to the sectional area of the second liquid flow port 22 for the condensate water to flow is K2, K2 is more than or equal to 2, the ratio of the sectional area of the second liquid flow port 22 for the condensate water to the sectional area of the third liquid flow port 31 for the condensate water is K1, K1 is more than or equal to 2, so that the situation that the local air speed is too high at the first liquid flow port 21 of the guide piece 2 is prevented, and the condensate water at the air outlet side of the evaporator cannot smoothly flow to the water outlet under the influence of the air flow resistance if the local air speed is too high at the first liquid flow port 21; meanwhile, when the condensed water level is higher than the third liquid outlet 31, the situation of blowing water caused by overhigh local wind speed is prevented.
If the ratio K2 of the cross-sectional area of the first liquid port 21 for the flow of the condensate to the cross-sectional area of the second liquid port 22 for the flow of the condensate is smaller than 2, and the ratio K1 of the cross-sectional area of the second liquid port 22 for the flow of the condensate to the cross-sectional area of the third liquid port 31 for the flow of the condensate is smaller than 2, the flow turbulence of the air flow on the condensate in the channel to the water outlet is obvious, and the splashing of the condensate also occurs in the first liquid port 21 of the guide member 2 located on the air outlet side of the evaporator in severe cases; if the ratio K2 of the cross-sectional area of the first liquid through hole 21 for the flow of the condensate to the cross-sectional area of the second liquid through hole 22 for the flow of the condensate is greater than or equal to 2, the ratio K1 of the cross-sectional area of the second liquid through hole 22 for the flow of the condensate to the cross-sectional area of the third liquid through hole 31 for the flow of the condensate is greater than or equal to 2, the drainage effect is better, and no air-blowing turbulence is generated.
Further, the water pan 1 is further provided with an overflow notch 13, and the water receiving assembly 100 further comprises a water sensor, wherein the water sensor is arranged below the overflow notch 13 and is used for giving an alarm when the overflow notch 13 overflows. For example, when the drainage of the drainage outlet is not smooth or is blocked, the condensed water can overflow from the overflow notch 13 when the water level to which the condensed water is gathered reaches the overflow notch 13 of the water receiving disc 1, at the moment, the water immersion sensor can be triggered to give an alarm to prompt that the drainage fault needs maintenance, and the condition that the condensed water overflows from the water receiving disc 1 in a large area is avoided.
The water receiving assembly 100 further comprises a water level switch and a water level switch fixing support 5, wherein the water level switch fixing support 5 is arranged on the water receiving disc 1, the water level switch is arranged on the water level switch fixing support 5, and the water level in the water receiving disc 1 can be detected through the water level switch so as to give an alarm according to the water level condition in the water receiving disc 1. For example, when the drain outlet is blocked or the drain is not smooth, the water level in the water receiving disc 1 exceeds a preset value, the water level switch gives an alarm, so that maintenance personnel can dredge the drain outlet in time, and the condition that condensed water overflows from the water receiving disc 1 in a large area when the drain outlet is blocked or the drain is not smooth is avoided. Wherein the lowest water level at which the water level switch can give an alarm is lower than the lowest water level of the overflow notch 13.
Correspondingly, the application also discloses an inter-column air conditioner, and referring to fig. 4, the inter-column air conditioner comprises an evaporator and the water receiving assembly 100 according to any one of the embodiments, wherein the water receiving assembly 100 is received at the bottom of the evaporator.

When the fins on the air outlet side of the evaporator 200 generate condensed water, the condensed water flows to the guide member 2 under the action of gravity, is collected into the water receiving disc 1 from the folded edge 24, flows to the drain outlet through the first liquid through hole 21, the first cavity and the second liquid through hole 22, and is discharged through the drain outlet, and when the fins on the air return side of the evaporator 200 generate condensed water, the condensed water flows to the guide member 2 under the action of gravity, is collected into the water receiving disc 1 from the folded edge 24, flows to the drain outlet through the third liquid through hole 31 and the second cavity 400, and is discharged through the drain outlet.
In the embodiment, the water outlet is arranged on the air return side of the evaporator, so that the direction of condensate water with lower temperature flows to the water outlet and the direction of return air with higher temperature are opposite to each other, the convection heat exchange is formed, the heat exchange efficiency is improved, and the low return air temperature is prevented. Meanwhile, as the fan cavity is arranged in the air outlet side area of the evaporator, the maintenance space of the air return side of the evaporator is larger than that of the air outlet side, and the water outlet and the water level switch are arranged on the air return side of the evaporator.
Further, the water receiving disc 1 is inclined to the air return side water outlet by a certain inclination during installation, that is, the horizontal height of the side, provided with the water outlet, of the water receiving disc 1 is lower than that of the side, not provided with the water outlet, of the water receiving disc 1, so that the condensate water can overcome the air flow disturbance resistance under the influence of self gravity, smoothly flows to the water outlet and is discharged from the water outlet. According to the application, the drain outlet is positioned at the lowest position of the water receiving disc 1, so that the influence of air flow resistance on the drainage of condensate water is reduced, meanwhile, the flowing-down condensate water with lower temperature flows in the direction of the drain outlet and the flowing-up return air with higher temperature flows in the opposite direction, so that convection heat exchange is formed, the heat exchange efficiency is increased, the temperature is further reduced, the heat exchange efficiency is improved, and the return air temperature is reduced.
In another embodiment, when the water receiving assembly 100 is assembled with the evaporator, the first liquid inlet 21 may be located on the air return side of the evaporator, and the second liquid inlet 22 and the water outlet are located on the air outlet side of the evaporator, and the water level switch and the overflow notch 13 may be located on the air outlet side of the evaporator. When the fins on the return air side of the evaporator generate condensed water, the condensed water flows to the guide piece 2 under the action of gravity, is collected into the water receiving disc 1 from the folded edge 24, flows to the drain outlet through the first liquid through hole 21, the first cavity 300 and the second liquid through hole 22, and is drained through the drain outlet; when the fins on the air outlet side of the evaporator generate condensed water, the condensed water flows to the guide member 2 under the action of gravity, is collected into the water receiving disc 1 from the folded edge 24, flows to the drain outlet through the third liquid outlet 31 and the second cavity 400, and is drained through the drain outlet.
