Description

[Detailed description of the invention] The present invention relates to a full-water stop device for a dehumidifier.

A conventional dehumidifier will be explained with reference to FIG.

In the figure, reference numeral 1 denotes a cabinet, and ventilation holes 1a and tb are formed on both sides of the upper part. 2 is an evaporator, 3 is a condenser, 4 is a fan motor, and 6 is a fan motor, which are arranged in sequence and blow indoor air as shown by the arrows. 6 is a compressor, and the evaporator 2.6 is a compressor. Together with the condenser 3, it constitutes a refrigeration cycle. 7°
is a dehumidified water storage tank in which water dehumidified by the evaporator 2 is collected via a dehumidifying tray 8. Reference numeral 9 denotes a support plate, one end of which is pivotally supported by the cabinet 1, and the other end of which is urged upward by a spring 1o. A dehumidified water storage tank is mounted on this support plate 9. Reference numeral 11 denotes a lever arm whose one end is pivotally supported, and a spring 12
The dehumidifying water storage tank 7 is supported by the supporting plate 9 and detects the placement of the dehumidified water storage tank 7 in conjunction with the support plate 9. Reference numeral 13 denotes a microswitch, which is fixed to a microswitch mounting plate 16 provided on the base 14, and is opened and closed by the vertical movement of the lever arm 11.

According to this conventional structure, since the water level of the stored water in the dehumidified water storage container 7 is detected by replacing the water level with the weight, it is possible to reliably detect when the amount of stored water is full. Therefore, the lever arm 11 must be operated reliably to interrupt the operating circuit.

In order to ensure reliable operation of the lever arm 11, the lever arm 11 is adjusted to
It is necessary to adjust the tension of springs 10 and 12 for each stand.
Manufacturing work is also troublesome.

Further, when dehumidified water is stored in the dehumidified water storage tank 7, since a spring is used, it is sensitive to vibrations from the outside, which causes malfunctions.

The present invention eliminates the above-mentioned conventional drawbacks.

Hereinafter, FIGS. 2 to 2 of the accompanying drawings showing one embodiment of the present invention.
This will be explained with reference to FIG.

In FIG. 2, reference numeral 1 denotes a cabinet 7, which has ventilation holes ta and 1b formed on both sides of its upper part. 2 is an evaporator, 3 is a condenser, 4 is a fan, and 5 is a fan motor. These are arranged in this order between ventilation holes 1a and 1b on both sides of the upper part, and indoor air is blown as shown by the arrow. A compressor 6 constitutes a refrigeration cycle together with the evaporator 2 and condenser 3.

8 is a dew pan, which is installed inside the cabinet 1.

A dehumidified water storage tank 7 stores condensation and dew water from the dew pan 8. A notch 7a is formed in one side of the storage tank 7.

The lever 17 is rotatably supported by a support arm 19 provided on the lower surface of the dew pan 8 via a shaft 18. In the lever 17, the float 16 rotates about the support arm 19 as a fulcrum, as shown by the arrow in FIG. 2, depending on the water level in the dehumidified water container 7. A microswitch 13 is fixed to a microswitch mounting plate 15 provided on a substrate 14, and is opened and closed by the other end of the lever in conjunction with the movement of the lever 17 in the direction of the arrow. Here, the dehumidified water storage tank 7 and the lever 17 are set as shown in FIG. 20 is a stopper provided on the lever 17, which stops the lever 17 and the support arm 1 as shown in FIG. 2 when the dehumidified water storage tank 7 is not inserted.
It is made so that the angle θ formed by 9 is not smaller than the angle θ.

Next, we will discuss the operation of the full water stop mechanism consisting of the above structure.
This will be explained with reference to FIGS.

FIG. 4 shows a state in which the dehumidified water storage tray 7 is not inserted, and the lever 17 connected to the float 16 has its rear end at position A due to the weight of the float 16, and at this time, the micro switch 13 is in OFF operation.

FIG. 6 shows the empty dehumidified water storage tank 7 installed, the lever 17 is set in the notch 7a of the dehumidified water storage tank 7, and the rear end of the lever 17 is in position B. is in the ON state.

FIG. 6 shows when the water level in the dehumidified water storage tank 7 is about to exceed position C, and the rear end of the lever 17 is disengaged from the microswitch 13, turning the microswitch 13 OFF.
make it work. Therefore, the operation circuit of the dehumidifier is cut off to prevent dehumidified water from overflowing into the dehumidified water storage tank 7.

Therefore, in order to detect the level of dehumidified water in the dehumidified water storage tank 7 with the float 16 and stop the operation of the dehumidifier,
The structure is simpler than the conventional structure that detects water level by replacing it with weight, and since it does not use a spring for weight detection, it is not affected by external vibrations.
This ensures reliable operation. Since the spring is not used in the μ case, there is no need to adjust the spring during manufacturing, making assembly easier. Furthermore, since the stopper 20 is provided on the lever i, it is possible to regulate the rotation angle of the lever 17 when the dehumidified water storage tank 7 is not inserted. This eliminates the rattling of the lever 17 in the left and right direction when it is set in the dehumidified water storage tank 7.
Further, the dehumidified water storage container 7 can be smoothly taken in and taken out.

As is clear from the above embodiments, the dehumidifier full water stop device according to the present invention includes a float that moves up and down depending on the amount of dehumidified water in the dehumidified water storage tank, and a float that is rotatably supported on the dehumidifier main body side, and whose tip is The lever connected to the float is integrally molded, and the other end of the lever is attached with a switch that is installed on the dehumidifier body and turns ON and OFF in conjunction with the rotation of the lever. Since the operation is controlled by detecting the water level, the structure is simpler than the conventional structure that detects the amount of stored water by replacing it with weight, and the amount of dehumidified water can be detected accurately. Since there is no spring structure, the time required for adjusting the springs can be reduced, and the assembly process is easy.
