Abstract

PURPOSE:To make it possible to prevent such conditions which allow water to be constantly collected in a water receiving tray of a dehumidifier and further prevent water leakage caused by the vibration of the dehumidifier or its slanting motion. CONSTITUTION:This equipment comprises a refrigeration device having a compressor, a condenser 3, a vaporizer 2 and a fan 12. a water receiving tray 1 which receives drain water produced from the vaporizer 2, a drain port 4 which drops the drain water into an waste water tank 6 from the water receiving tray, a reserve drain port 5 and an overflow sensor.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying device using a refrigerating device.

[0002]

2. Description of the Related Art A conventional dehumidifier will be described with reference to the drawings.

FIG. 1 is a schematic front view of a conventional dehumidifier,
2 is a schematic vertical sectional view of FIG.

The dehumidified water generated by the evaporator 2 is dripped from the drain port 4 provided in the water receiving tray 1 to form a drain tank 6.
It is supposed to accumulate in. However, if the drain port 4 is closed for some reason, the dehumidified water will overflow from the water pan. Therefore, in order to deal with this water leakage, the spare drain port 5 is provided at a position slightly higher than the drain port near the evaporator 2 so that it does not normally function, and when the drain port 4 is closed, dehumidified water is removed from the water tray. Is spilled from the spare drain port 5 without overflowing and is stored in the drainage tank 6.

[0005]

However, when the conventional dehumidifier as described above is operated, the spare drain port is located near the evaporator, and therefore the spare drain port as well as the spare drain port due to icing or the like. Mouth may also be blocked. Further, especially when a spare drain port is provided in the lower part of the evaporator, the dehumidified water was dripped directly into the drain tank through the spare drain port even when the drain port was not closed. In addition, dehumidification water is less likely to drip from the spare drain port due to the effect of water retention by the fins of the evaporator. Also, during continuous drainage in which a hose or the like is connected to the drain port 4 to continuously discharge the drain out of the machine, if the drain port is closed, water will drop from the spare drain port, and the full water stop mechanism will work later to operate the main body. Although the drain port is blocked because it is stopped, if the drain port is not continuous drainage, even if the drain port is blocked, the spare drain port will work and there will be no change in operation. If you do not notice the blockage of the drain unless it is, in this state water will always be stored in the water tray and there is a possibility of water leakage due to vibration or inclination.

[0006]

In order to solve the above problems, the present invention provides a drain port of a water receiving tray for drain water generated from a refrigeration cycle including a compressor, a condenser, an evaporator, a blower and the like. A dehumidifier for dripping from the tank and storing it in a drainage tank is constructed, and a spare drain port that opens slightly higher than the drain port is provided under the condenser. Further, in the present invention, in order to prevent water retention by the fins of the condenser, a spare drain port is provided so as to have a predetermined gap between the condenser and the spare drain port. Further, according to the present invention, the dehumidifier is provided with a water tray provided with an overflow sensor for warning the compressor to stop or to close the drain port.

[0007]

According to the present invention, even when the drain port is closed by the above means, the dehumidified water can be dropped into the drain tank through the spare drain port without overflowing from the water receiving tray. Even if icing or the like occurs and the drain port is blocked, the spare drain port is on the condenser side, so it will not be blocked by icing, etc., and the specified gap between the condenser and the spare drain port will be maintained. Therefore, the dehumidifying water can be dripped into the drain tank through the spare drain port without any influence of water retention by the fins of the condenser. Further, the overflow sensor provided under the spare drain port can detect the drain port blockage, stop the compressor, and display the drain blockage warning display to notify the abnormality.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The operation of one embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 3 and 4, reference numeral 1 denotes a water tray on which not only the evaporator 2 but also the condenser 3 is arranged. The drain port 4 is installed substantially in the center of the evaporator 2 and the condenser 3, and the preliminary drain port 5 is located directly below the condenser 3. In order to provide a predetermined gap a between the spare drain port 5 and the condenser 3 and to minimize the distance between the evaporator 2 and the water tray 1, the water tray 1 is as shown in FIG. It has a shape.

In the above dehumidifier, the dehumidified water normally produced by the evaporator 2 is dripped from the drain port 4 arranged substantially in the center of the evaporator 2 and the condenser 3 and accumulated in the drain tank 6.
Since the spare drain port 5 is located higher than the drain port 4 and is under the condenser, the dehumidified water does not usually drip from this drain port. In addition, the condenser 3 and the spare drain port 5
If there is no distance between the dehumidifying water and the fins of the condenser 3 due to surface tension, the dehumidifying water may not easily drip from the preliminary drain port 5. Since the predetermined clearance a is set, the dehumidified water is accumulated in the drainage tank 6 through the preliminary drain port 5 without being affected by the water retention by the fins of the condenser 3.

However, if the drain port 4 is closed for some reason, the dehumidified water generated by the evaporator 2 loses its place and begins to accumulate in the water tray 1, but when it accumulates to a certain extent, it is below the condenser 3. The dehumidifying water starts to drip from the spare drain port 5 provided at a position higher than the drain port 4, and a signal is sent to the controller 8 by the overflow sensor 7 provided below the spare drain port 5. FIG. 6 is a block diagram showing the configuration of the control device. A signal is sent from the controller 8 to the drain blockage warning display device 9, and the drain blockage warning display device functions. Without this drain blockage warning display device 9, during continuous drainage, if the drain port is blocked, water will drop from the spare drain port, and the filling mechanism will work later to stop the main body, so you can confirm the drain port blockage. If it is not, even if the drain port is closed, the spare drain port will work, and water will flow through this spare drain port 5 and will fill the tank and the full-water mechanism will work. Therefore, a warning of drain blockage is required. When the drain warning display device 9 is not provided, the compressor 11 is stopped by the signal from the overflow sensor 7. Further, the warning display and the compressor may be stopped at the same time.

[0012]

As is apparent from the above description, the present invention has the following advantages.
A dehumidifier is configured to drip drain water generated from a refrigeration cycle composed of a compressor, a condenser, an evaporator, a blower, etc., from a drain port of a water tray and store it in a drain tank.
A spare drain port that opens slightly higher than the drain port is provided under the condenser, and even if the drain port is blocked due to freezing, etc., the spare drain port is on the condenser side. It will not be blocked due to freezing. Also, because there is a specified gap between the condenser and the spare drain port, there is no effect of water retention by the fins of the condenser, and the dehumidified water does not overflow from the water tray and passes through the spare drain port to the drain tank. Water can be prevented from leaking from the dehumidifier due to dripping and clogging of the drain port.The overflow sensor provided at the bottom of the spare drain port can detect clogging of the drain port. Can inform you.
