Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for stopping full drain water in a drain tank of a dehumidifier.

[0002]

2. Description of the Related Art FIG. 6 shows, for example, Jpn.
FIG. 7 is a cross-sectional view showing a conventional dehumidifier shown in Japanese Patent Publication No. JP-A-2003-264, and FIG. In these figures, the refrigerant compressed by the compressor (not shown) enters the condenser 2 and is condensed, and then enters the cooler 3. Cooler 3
The refrigerant evaporated in step 1 returns to the compressor, and the same cycle is repeated again. Here, the moist air touches the cooler 3 to drop moisture in the air into water drops, and the drain water is guided to the drain tank 4. At the same time, the cooled air is warmed and blown out through the condenser 2. The drain water led to the drain tank 4 is
When the drain tank 4 is full, the main switch 8 is automatically turned off to prevent overflow.

Next, the operation of the full water stop device for turning off the operation of the main switch 8 to prevent overflow will be described with reference to FIG. In FIG. 6, 4 is a drain tank, 5 is a float whose one end is rotatably fixed to a shaft 6 which is orthogonal to the insertion direction of the drain tank 4, and an operating piece 7 is provided at its side end.
Is projected. The main switch 8 is turned on / off via the operation lever 9 by pressing the operation piece 7 provided in a protruding manner. The float 5 whose one end is rotatably supported in the drain tank 4 has a built-in float 5, and the drain water in the drain tank 4 increases.
By decreasing, it moves up and down. In addition, the operation piece 7 projecting from the float 5 is transferred via the operation lever 9 of the main switch 8 to
The main switch 8 is operating. That is, when the drain water in the drain tank 4 is small, the float 5 is lowered, and in this state, the main switch 8 is pressed by the operation lever 9 to be in the ON state. Then, as the drain water in the drain tank 4 becomes full, the float 5 rises, and finally the operation piece 7 at the tip of the float 5 is disengaged from the operation lever 9, and the main switch 8 is instantly turned off.

[0004]

Since the conventional full water stop device for the dehumidifier is constructed as described above, when the drain tank 4 is housed in the dehumidifier body, if it is strongly pushed in, the float will be caused by its impact. The dehumidifier is not operated because 5 remains in the splashed state. Therefore, there is a problem that the drain tank 4 has to be pulled out again and inserted again, and the operation must be handled softly.

The present invention has been made in order to solve the above-mentioned problems, and the dehumidifier can be operated reliably even if the drain tank is strongly inserted, and the float can be eliminated. It is an object of the present invention to obtain a full-water stop device for a dehumidifier that is capable of stabilizing the amount of drain water in the drain tank at the same time as it is possible.

[0006]

【Example】

Example 1. 1 and 2 are a longitudinal sectional view of a dehumidifier showing an embodiment 1 of the present invention and an exploded perspective view of a drain tank portion.
In the figure, the same reference numerals as those in FIGS. 6 and 7 indicate the same parts. 1
1 is a base, on which a compressor 1 and a drain tank 4 are placed,
Each is partitioned by a partition plate 12. Reference numeral 13 is a drain pan placed on the partition plate 12, and a cooler 3, a condenser 2, a blower 14 and an electric motor 15 are provided on the upper part of the drain pan, and these are housed in a cabinet 16. In the drain tank 4, a conductive piece A20 is fixed to the outer wall 19 side of the rising wall 17, and a "U-shaped" conductive piece B21 extending from the inner wall 18 side to the outer wall 19 side.
Are installed. The partition plate 1 inside the dehumidifier body
2, the electrode portions A22 and B23 and the electrode portion C2 are respectively brought into contact with the conductive pieces A20 and B21.
4 and D25 are placed on the electrodes, and a low voltage is charged in each of the electrodes, and the electric circuit is turned on when the electrodes A22 and B23 are electrically connected and turned off when the electrodes C24 and D25 are electrically connected. It is assembled.

Next, the operation will be described. After the refrigerant compressed by the compressor 1 enters the condenser 2 and is condensed, the cooler 3
to go into. The refrigerant evaporated in the cooler 3 returns to the compressor 1 and repeats the same cycle again. Here, the moist air is sucked into the blower 14 and comes into contact with the cooler 3 to make moisture in the air into water droplets. The water is collected by the drain pan 13 and then led to the drain tank 4. At the same time, the cooled air is warmed and blown out through the condenser 2 to complete the dehumidification operation.
The drain water guided to the drain tank 4 gradually raises its water level, and when the drain water reaches the conductive piece B21 provided in the drain tank 4, the conductive water between the conductive pieces B21 and B21 is electrically connected by the drain water. As a result, the electrode portions C24 and D25 are naturally brought into conduction, the electric circuit of the dehumidifier main body is turned off, and the dehumidifier is stopped with full water. Further, in a state where the drain tank 4 is not inserted, the electrode portions A22 and B23 do not come into contact with the conductive piece A20 provided in the drain tank 4, so that the conductive state is not established.
The signal turns off and the dehumidifier body does not start operation.

Example 2. In the first embodiment, the case where the electrode portion is directly attached to the partition plate 12 has been described.
As shown in FIG. 3, the electrodes A22 to D25 are cantileveredly fixed to the partition plate 12 on the side of the machine room 26 in which the compressor 1 is placed,
By mounting the one end portion 28 so as to project from the opening hole 29 provided in the partition plate 12 toward the drain tank storage chamber 27 side, the one end portion 28 of the electrode portions A22 to D25 can obtain elastic force and can be further drained. Conductive piece A20 / B of tank 4
21 is ensured, and even if there is some variation in the insertion state of the drain tank 4, the electrode parts A22 to D2
5 and the conductive pieces A20 and B21 can be brought into contact with each other, and the product quality is improved.

Embodiment 3. Further, in the above-described embodiment, the case where the drain tank 4 is provided with a plurality of "U-shaped" conductive pieces B21 is shown, but as shown in FIGS. By integrally molding the conductive piece C30 with the drain tank 4 so that the inner wall 18 and the outer wall 19 surfaces communicate with each other, the conductive piece B21 and the like may be accidentally removed when drain water stored in the drain tank 4 is discharged. This eliminates the problem, and it is possible to obtain a high quality dehumidifier full water stop device.
