Technical field

The invention relates to the technical field of indoor dehumidification equipment, in particular to a water path structure and a dehumidifier for a water receiving tray of a dehumidifier.

Background technique

Dehumidifiers, also known as dehumidifiers, dryers, dehumidifiers, can generally be divided into two categories: household dehumidifiers and industrial dehumidifiers, belonging to a small member of the refrigeration and air conditioning family. Generally, a dehumidifier consists of a compressor, a heat exchanger, a fan, a water container, a casing, and a controller. It mainly includes industrial dehumidifiers (applied to underground projects such as subways and civil air defenses), high-temperature dehumidifiers, high-temperature dehumidifiers (used in high-temperature dehumidification places such as drying workshops), and fresh air dehumidifiers (used in places with high purification levels). Water-cooled dehumidifier, temperature-controlled dehumidifier (where wet load, cold/heat load are simultaneously adjusted).

The working principle of the dehumidifier is: the humid air is drawn into the machine by the fan and passes through the heat exchanger. At this time, the water molecules in the air condense into water droplets, and the treated dry air is discharged outside the machine, so that the indoor humidity is maintained at the cycle. Suitable relative humidity.

The condensed water generated by the existing dehumidifier is mainly collected by the water receiving tray and collected in the water tank or discharged directly through the water pipe. The water receiving tray is mostly a single water guiding tray, and the condensed water on the evaporator is discharged through the water outlet. The water tank or the pipeline is discharged. Because there is not only one area where the condensed water is formed on the evaporator, a variety of water flow disturbances are usually formed, which cannot be promptly and promptly discharged. Further, no corresponding anti-clogging equipment is provided.

The evaporator 3 is used to heat the air drawn into the dehumidifier Change and condense water molecules in the air to the lower part.

When the dehumidification is performed, the condensed water formed in the lower portion of the main body of the evaporator 3 occupies a large proportion of the displacement of the water tray 1, so that the drain of the condensed water formed at the main body of the evaporator 3 is the main flow path, and the refrigerant of the evaporator 3 is the refrigerant. The condensed water formed at the U-bend of the U-tube 5 and the elbow 4 of the evaporator 3 is smaller than the condensed water of the main body of the evaporator 3, so the U-bend of the refrigerant U-tube 5 and the condensed water formed at the elbow 4 The drainage channels are respectively the secondary flow path and the primary flow path. Therefore, the design of the drainage channel needs to divide the drainage channel for the amount of different condensed water formed by the main body of the evaporator 3, the U-bend and the elbow 4, respectively.

Specifically, the drainage channel includes a first flow path 6 corresponding to a lower portion of the main body of the evaporator 3 at a projection of the water receiving tray 1, a U-shaped lower portion corresponding to the refrigerant U tube 5, and a condenser 2 at the water receiving tray 1 A second flow path 7 is provided at the projection, and the first flow path 6 and the second flow path 7 are in communication with the drain opening 12 on the water receiving tray 1. Since the first flow path 6 is located at the lower portion of the main body of the evaporator 3, most of the condensed water flows from the first flow path 6 to the drain port 12; the second flow path 7 is located at the lower portion of the U-bend of the refrigerant U-tube 5 and the lower portion of the condenser 2, mainly The condensed water on the U-bend side of the refrigerant U-tube 5 is collected and the part of the condensed water is guided to the drain port 12.

As shown in FIG. 3, in order to facilitate drainage of the respective drain passages and prevent water accumulation in the water receiving tray 1, the lowest point of the portion where the drain port 12 is connected to the water receiving tray 1 is not higher than all the water passages of the water receiving tray 1. The lowest point of the water level.

The first flow path 6 and the second flow path 7 are separated by a first rib 9 to form a split. The condensed water in the first flow path 6 and the second flow path 7 can be merged at a position close to the drain port 12 and discharged along the drain port 12.

Further, a plurality of drainage plates 14 are respectively disposed in the first flow path 6 for conveying the large-flow water flow to the water discharge port 12 in a distributed manner. The drainage plate 14 can be distributed along the flow direction of the first water flow path 6, and can be arranged in a single row or a double row according to the power of the dehumidifier.

Further, a drainage plate 14 may be disposed in the second flow path 7 for flowing the condensed water in the second flow path 7 to smoothly flow out. The drainage plate 14 can be vertically disposed at a water collecting area of the condensed water condensation region of the second flow path 7 facing the U-bend of the refrigerant U tube 5 and at a drainage path of the second flow path 7 below the condenser 2. At the connection port, the condensed water in the second flow path 7 is divided into two.

One side is used to separate the overflow port 13 from the drain port 12 and the first flow path 6 to ensure that the overflow port 13 is only blocked at the drain port 12, that is, the water level in the water receiving tray 1 is higher than the set safety. At the water level line, the condensed water flows out through the overflow port 13. This arrangement effectively ensures that the water level in the water receiving tray 1 can be maintained by the drain port 12 only when the water level in the water receiving tray 1 is set, and the overflow port 13 does not participate in the discharge of the condensed water.

Preferably, as shown in FIG. 4-6, the lowest end of the water outlet end of the overflow opening 13 extends to the outside with a guide groove 15 for draining and draining. The flow guiding groove 15 has a circular arc shape in cross section, and the depth thereof increases in the direction toward the water outlet end of the overflow opening 13 , and the guide The two side edges of the launder 15 are in contact with and flush with the groove bottom of the overflow port 13.
