Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for stopping the filling of drain water into a drain tank of a dehumidifier.

[Conventional technology]

FIG. 4 is a sectional view showing a conventional dehumidifier disclosed in, for example, Japanese Utility Model Application Publication No. 54-36959, and FIG. 5 is a perspective view of the drain tank portion of FIG. 4. In these figures, refrigerant compressed by a compressor (not shown) enters a condenser 2 and is condensed, and then enters a cooler 3. The refrigerant evaporated in the cooler 3 returns to the compressor and repeats the same cycle again. Here, the humid air touches the cooler 3 to remove moisture from the air, and the drain water is led to the drain tank 4, at the same time the cooled air is warmed and blown out through the condenser 2. . When the drain water led to the drain tank 4 becomes full, the main switch 8 is automatically turned off to prevent overflow.

Next, the operation of the full-water stop device that turns off the main switch 8 and prevents overflow will be explained with reference to FIG. 5. In Figure 5, 4 is a drain tank;
A float has one end rotatably supported on a shaft 6 perpendicular to the insertion direction of the drain tank 4, and has an operating piece 7 protruding from its side end. The main switch 8 is turned on and off via an operating lever 9 by pressing the protruding operating piece 7. A float 5 built into the drain tank 4 with one end pivotally supported moves up and down as the drain water in the drain tank 4 increases or decreases. Further, an operating piece 7 protruding from the float 5 operates the main switch 8 via an operating lever 9 of the main switch 8.
That is, when the drain water in the drain tank 4 is low, the float 5 is lowered, and in this state, the main switch 8 is pressed by the operating lever 9 to turn it on.
I am in a state of 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
When the control lever 9 is removed, the main switch 8 is instantly activated.
It will be in the OFF state.

[Problem that the invention attempts to solve]

The conventional dehumidifier full-water stop device is constructed as described above, so when the drain tank 4 is inserted into the dehumidifier body, if it is pushed in with force, the float 5 will pop up due to the impact and be inserted. As a result, the main switch 8 remains in the OFF state and the dehumidifier does not operate. For this reason, there were problems such as having to pull out the drain tank 4 again and reinserting it again, and also having to operate it in a soft manner.

This idea was devised to solve the above-mentioned problems, and includes a full-water stop device that allows the float's operating piece to reliably press the main switch's operating lever even if the drain tank is strongly inserted. The purpose is to obtain.

[Means for solving problems]

The full water stop device for a dehumidifier according to this invention has one end of the float rotatably supported on an axis parallel to the direction of insertion of the drain tank, and an operating piece provided at the side end of the float controls the main switch. This ensures that the operating lever is pressed.

[Effect]

The dehumidifier full-water stop device of this invention has one end of the float rotatably supported on an axis parallel to the direction in which the drain tank is inserted, so that even if the drain tank is strongly inserted, the float will not spring up. The main switch can be turned on and off without fail.

〔Example〕

1 and 2 are a longitudinal cross-sectional view and an exploded perspective view of a drain tank portion of a dehumidifier showing an embodiment of this invention. In Figures 1 and 2, Figure 4,
The same reference numerals as in FIG. 5 indicate the same parts, and 11 is a base on which the compressor 1 and the drain tank 4 are placed, and are partitioned from each other by a partition plate 12. 13 is a drain pan placed on the partition plate 12;
On this upper part, there is a cooler 3, a condenser 2, and a blower 14.
and an electric motor 15, which are housed in a cabinet 16. The float 5 is inserted in the direction of insertion of the drain tank 4 (arrow X direction)
One end of the shaft 10 is rotatably supported on a shaft 10 parallel to the shaft 10. Further, an operating piece 7 is provided protruding from the side end of the float 5, and the main switch 8 is activated by pressing or separating the operating lever 9 with this operating piece 7.
It can be turned on and off.

Next, the operation will be explained. The refrigerant compressed by the compressor 1 enters the condenser 2 and is condensed, and then enters the cooler 3. The refrigerant evaporated in the cooler 3 returns to the compressor 1 and repeats the same cycle again. Here, the humid air is sucked into the blower 14 and comes into contact with the cooler 3 to turn the moisture in the air into water droplets, and after the water is collected in the drain pan 13, it is led to the drain tank 4.
At the same time, the cooled air is heated and blown out through the condenser 2. The drain water led to the drain tank 4 gradually raises its water level and eventually causes the float 5 to rise. At this time, since the drain tank 4 is inserted, the operating piece 7 provided at the side end of the float 5 presses the main switch 8 via the operating lever 9, so the main switch 8 is turned ON. The dehumidifier is in operation. When the water level in the drain tank 4 further rises, the float 5 also rises further, and finally the operating piece 7 at the side end of the float 5 switches the main switch 8.
The main switch 8 is instantly released from the operating lever 9.
The dehumidifier will be turned off and the dehumidifier will stop operating. Further, the operating lever 9, which has once been disengaged, is placed under the operating piece 7 of the float 5 to prevent the main switch 8 from being operated again.

In the above embodiment, the operating lever 9 of the main switch 8 is rectangular, and the operating lever 9 and the operating piece 7 of the float 5 are pressed or separated, and the main switch 8
As shown in Fig. 3, the upper end of the operating lever 9 is connected to the float 5.
If the inclined part 17 is provided in accordance with the rising angle of the float 5, the operation lever 9 and the operation piece 7 of the float 5 can be removed more smoothly, and the operation of the dehumidifier can be stopped with the full water level of the drain tank 4 always at a constant level. I can do it.

[Effect of idea]

As explained above, this device has one end rotatably supported on an axis parallel to the insertion direction of the drain tank, so that the float moves upward together with the operating piece as drain water increases in the drain tank. Even if the drain tank is strongly inserted, the float does not pop up, and the main switch can be turned on reliably, which has the effect of improving operability when inserting the drain tank.
