Description

Condensed water evaporation device

Technical Field

The invention relates to refrigeration equipment, in particular to a condensed water evaporation device for removing condensed water in the refrigeration equipment.

Background

In a refrigeration device such as an air conditioner, a cold/ice water machine, a refrigerator, and a low temperature refrigerator, a temperature of a cold end, such as a refrigerant evaporator, is rapidly decreased to a temperature below a Dew point temperature (Dew point temperature) during operation, so that water vapor in air is condensed on the refrigerant evaporator to form condensed water. The condensed water is attracted by gravity to drip downwards, and unnecessary accumulated water caused by the condensed water can be avoided only by a device for draining the condensed water.

There are two ways of removing the condensed water. The first way is to collect the condensate by a pipe and drain it through a drain pipe in the room. This is often seen in air conditioners. However, the wiring of the drain line is limited by the design of the building itself, and the location where the refrigeration unit is installed does not have access to the receiving opening of the drain line. A second mode is to collect the condensed water by means of a water collection tank and to convey the condensed water to a receiving opening of a water discharge pipe by means of an elongated pipe body; or the condensed water in the water collecting tank is poured out regularly by manpower.

Either the arrangement of drainage equipment to drain the condensed water or the manual dumping of the condensed water in the water collecting tank will cause inconvenience.

Referring to fig. 1 to 8, a condensate water evaporation apparatus 1 according to an embodiment of the present invention includes a water collection tank 10, a fixing frame 20, a spraying water tank 30, a water pump 40, a pipeline 50, a fan 60, a water level sensor 70, a control circuit board 80, and a water curtain 90. The condensed water evaporation device 1 is suitable for various refrigeration equipment and collects condensed water generated by the cold end of the refrigeration equipment; the refrigeration equipment comprises but is not limited to a cold air machine, a cold/ice water machine, a refrigerator and a low-temperature refrigerated cabinet, and the cold end comprises but is not limited to a refrigerant evaporator.

As shown in fig. 1 to 4, the water collection tank 10 has an opening 11 and is for storing the condensed water. The water collection tank 10 may be configured by a suitable water conduit to introduce the condensed water from the cold end of the refrigeration equipment into the water collection tank 10 for storage. The fixing frame 20 is fixed to the water collecting tub 10 and corresponds to the opening 11. The fixed frame 20 has opposite top and

bottom portions

21 and 22, and opposite front and back surfaces 23 and 24. The bottom 22 is arranged corresponding to the opening 11 of the water collection sump 10; preferably, the bottom portion 22 is fixed to two opposite side edges of the opening 11 by screws, snaps, adhesives, or the like. Front 23 has front vents 231 and back 24 has back vents 241, with front vents 231 and back vents 241 being in communication with each other.

As shown in fig. 1 to 4, the spray water tank 30 is provided at the top 21, and the spray water tank 30 communicates with the inside of the fixed frame 20 with a plurality of spray holes 31. A water curtain 90 is provided inside the fixing frame 20. The water curtain 90 is formed by folding fiber sheets such as corrugated paper to form water curtain sheets with specific corrugations, and then a plurality of water curtain sheets are overlapped to form a honeycomb structure, so that the contact area with air is increased. The water flows from top to bottom to form a water film with the same total area on the surface of the water curtain sheet, and the water film can be easily evaporated.

As shown in fig. 1 to 5, a water pump 40 is provided in the water collection sump 10. The water pump 40 has a water inlet 41 and a water outlet 42. The water pump 40 is used for sucking the condensed water from the water inlet 41 and pushing the condensed water from the water outlet 42. The pipe 50 connects the water pump 40 and the shower water tank 30. The spray water tank 30 further has an inlet pipe 32 located on an outer side surface of the spray water tank 30, and the inlet pipe 32 communicates with the inside of the spray water tank 30. The pipe 50 has one end connected to the water inlet pipe 32 and the other end connected to the water outlet 42 of the water pump 40, thereby connecting the water pump 40 and the shower water tank 30.

As shown in fig. 1 to 4, the fan 60 is disposed corresponding to the rear ventilation opening 241, so as to blow air from the rear surface 24 through the rear ventilation opening 241 and the front ventilation opening 231, or draw air from the rear surface 24 through the front ventilation opening 231 and the rear ventilation opening 241, so as to force the air flow to pass through the water curtain 90, thereby accelerating evaporation of the condensed water on the water curtain 90. Specifically, the area of the front vent 231 is larger than that of the rear vent 241; the area of rear vent 241 matches the size of fan 60 and the area of front vent 231 is as large as possible to cover a large portion of front face 23. Preferably, the fan 60 is mounted to the fan case 62 so as to be fixed to the rear surface 24, and the fan case 62 surrounds the rear ventilation opening 241 such that the fan 60 corresponds to the rear ventilation opening 241. As shown in fig. 1 and 2, the condensate evaporation apparatus 1 further includes a protection net 52 fixed in the fixing frame 20 and shielding the rear vent 241, thereby securely isolating the water curtain 90 from the fan 60.

As shown in fig. 1, 2 and 4, a water level sensor 70 is provided in the water collection sump 10 to detect a water level height of the water collection sump 10. The drawings of the present invention illustrate a float sensor as the water level sensor 70, and specifically, the water level sensor 70 may be a photoelectric liquid level sensor, a multi-point liquid level sensor, a separation type liquid level sensor, or a capacitive liquid level sensor.

As shown in fig. 1, 2 and 6, the control circuit board 80 is electrically connected to the water pump 40, the fan 60 and the water level sensor 70. The control circuit board 80 is also connected to a power source 2, which may be a battery or a power adapter, to obtain power to supply the water pump 40, the fan 60, and the water level sensor 70. Preferably, the condensate water evaporating apparatus 1 further includes a circuit box 81 provided to the back surface 24 of the fixing frame 20, and the condensate water evaporating apparatus 1 further includes an outer cover 82. The control circuit board 80 is fixed inside the circuit box 81, and the outer cover 82 is fixed to the circuit box 81 and seals the circuit box 81.

Preferably, the fixing frame 20, the shower bath 30, the fan case 62, and the circuit box 81 may be integrally formed to form a single case and manufactured using a plastic injection molding process. In different embodiments, the fixing frame 20, the spraying water tank 30, the fan case 62 and the circuit box 81 may be independent components, and are fixed to each other by fastening, or gluing to form the housing.

As shown in fig. 6, 7 and 8, regardless of the form of the water level sensor 70 or the manner of detecting the water level, the water level sensor 70 can send corresponding signals at least when the water level of the water collection tank 10 reaches the high water level H and the low water level L; wherein the high water level H is greater than the low water level L, and the low water level L is not lower than the height of the water inlet 41 of the water pump 40. In fig. 6, solid arrows indicate signal transmission paths, and broken arrows indicate condensed water conveyance paths.

For example, the water level sensor 70 may simply generate a signal corresponding to the high water level H by the float touching a switch, a reed switch in a magnetic ring trigger circuit in the float, or a hall element when the float reaches the high water level H; alternatively, the water level sensor 70 may continuously provide a signal corresponding to the water level height, and the signal transmitted when the water level height reaches the high water level H is naturally a signal corresponding to the high water level H. Similarly, the water level sensor 70 may simply generate a signal corresponding to the low water level L by the float touching a switch, a reed switch in a magnetic ring trigger circuit in the float, or a hall element when the float reaches the low water level L; alternatively, the water level sensor 70 is continuously providing a signal corresponding to the water level height, and the signal transmitted when the water level height reaches the low water level L is naturally a signal corresponding to the low water level L.

As shown in fig. 6, 7 and 8, the control circuit board 80 is used for receiving the signal corresponding to the high water level H and the signal corresponding to the low water level L from the water level sensor 70 to start the water pump 40 and the fan 60 or to shut down the water pump 40 and the fan 60.

As shown in fig. 6 and 7, when the control circuit board 80 receives a signal corresponding to the high water level H, the control circuit board 80 starts the water pump 40 and the fan 60. At this time, the water pump 40 sucks the condensed water from the water inlet 41, and pushes the condensed water from the water outlet 42 to the spray water tank 30 through the pipe 50. As shown in fig. 5, after being fed into the spray water tank 30, the water is sprayed on the water curtain 90 through the plurality of spray holes 31. At the same time, the fan 60 blows forced air flow through the water curtain 90 to accelerate evaporation of the condensed water on the water curtain 90, thereby rapidly removing the condensed water in the water collection sump 10.

As shown in fig. 1, since the water does not necessarily completely evaporate in the upward and downward flow of the water curtain 90, it is accumulated toward the bottom 22 of the fixed frame 20. Therefore, the bottom 22 of the fixed frame 20 is further provided with an overflow opening 221, and the moisture accumulated by the trickling of the water curtain 90 can be returned to the water collection tub 10 through the overflow opening 221 and the opening 11 corresponding to the opening 11 of the water collection tub 10 to perform the cycle of spraying again.

As shown in fig. 6 and 7, when the control circuit board 80 receives a signal corresponding to the low water level L, the control circuit board 80 turns off the water pump 40 and the fan 60. At this time, the water pump 40 stops operating, and the water pump 40 is prevented from being burnt out because the water pump 40 cannot suck the condensed water from the water inlet 41 and idles.

In one or more embodiments, as shown in fig. 9, the condensate evaporation device 1 is disposed in a well-ventilated area, and an air supply system is provided to drive an air flow through a water curtain 90, for example, the condensate evaporation device 1 is disposed in a ventilation duct. In this case, the fan 60 may be omitted, and the air flow driven by the air supply system passes through the water curtain 90, so as to accelerate the evaporation of the condensed water on the water curtain 90.

In summary, the condensed water evaporation apparatus 1 of the present invention utilizes the water pump 40 and the spray water tank 30 to spray the condensed water on the water curtain 90, so that the condensed water can be removed by evaporation. Therefore, it is not necessary to dispose a drain to drain the condensed water, and it is not necessary to pour the condensed water of the water collecting tub 10 by a human power. In at least one embodiment, the evaporation of the condensate on the water curtain 90 may also be accelerated by forcing an air flow through the water curtain 90 by the fan 60. Therefore, the present invention effectively overcomes the problems or inconvenience of removing the condensed water in the prior art, and has high industrial utilization value.

While the condensate evaporation apparatus 1 provided in the embodiment of the present invention has been described in detail, it will be apparent to those skilled in the art that the embodiments and applications of the invention can be modified. In view of the foregoing, it will be seen that this invention is not limited by the foregoing description, but is intended to cover all equivalent modifications and changes in accordance with the spirit and scope of the invention as defined by the appended claims.
