Abstract

PURPOSE:To reduce the number of component parts and facilitate a workability of assembling operation by a method wherein a loss is reduced as compared with that of a structure for sensing a weight of volume of stored water by sensing the volume of stored water under a movement of center of gravity of the drain tank, the drain tank is eccentrically displaced and resiliently supported by a resilient body for correcting an inclination of the drain tank. CONSTITUTION:A drain tank 19 has a handle 22 at the upper operator's side, a fulcrum point 23 is formed near the handle 22, an actuator 25 of the microswitch 24 is depressed in front of the handle 22 by a lever 26 operating a dehumidifier. A resilient body 27 such as a leaf spring is set by screws so as to project substantially in a horizontal direction at a position of the partition plate 21 oppositely faced against the diagonal bottom surface of said fulcrum point 23. With the above arrangement, the drain tank 19 is held such that the fulcrum point 23 is engaged with the concave part 29 of the fulcrum point 28 and the diagonal bottom surface of the fulcrum point 23 is held by the resilient body 27. When the dehumidified water is filled in the drain tank 19, the center of gravity of the drain tank 19 is moved and the drain tank 19 starts to rotate around the fulcrum point 23.

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 same figure,
Reference numeral 1 denotes a dehumidifier main body, in which a compressor 2, an evaporator 3, and a pseudo-condenser 4, which constitute a refrigeration cycle, are respectively installed. A fan 5 sucks air through an intake grill 6 and discharges it through an outlet grill 7. 8 is the drainage tank, compressor 2
The dehumidified water condensed by the evaporator 3 drips into the water tray 9, and is then stored in the drain tank 8 from the water tray 1o.

This drainage tank 8 is placed on a tank pedestal 11, and the tank pedestal 11 is supported by a fulcrum 12 and a compression spring 13. Rotates around. In addition, the tank holder 11 has a structure in which an L-shaped lever arm 15 that is linked to a micro switch 14 that detects full water is locked, and the lever arm 15 is connected to the drain tank 8 and the tank holder 1.
1, the actuator 16 of the microswitch 14 is pressed to operate the dehumidifier.And when the drain tank 8 is filled with water, the compression spring 13 is compressed and at the same time the lever arm 16 is lowered, and the lever arm 15 is disconnected from the actuator 16 of the microswitch 14, and the operation of the dehumidifier is stopped. Also, if the drain tank 8 is removed from the dehumidifier main body 1, the micro switch 14. A tension spring 1 has one end attached to a holding fitting 17 holding the lever arm 16 and the other end attached to the lever arm 16.
8, the lever arm is separated from the actuator 16 of the microswitch.

The above structure has the disadvantage that there are a very large number of parts that hold the drain tank, which increases material costs and manufacturing man-hours.Also, adjustment work is required to eliminate variations in the spring constants of the compression spring and tension spring. However, due to the cumbersome adjustment process, dehumidified water sometimes overflows from the drain turn, wetting the room or reducing electrical insulation.

The present invention eliminates the drawbacks found in the prior art water stop device.

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

,','- In the figure, the drain tank 19 is installed beside the compressor 2o, and the drain tank 19 and the Uf compressor 20 are separated by a partition plate 21. The drain tank 19 has a handle 22 in front of the upper part, and a fulcrum 23 is formed near the handle 22, and a lever 2 is provided in front of the handle 22 for pushing the actuator 26 of the micro switch 24 to operate the dehumidifier.
6 is provided. Further, an elastic body 27 such as a leaf spring is screwed to a position of the partition plate 21 opposite to the diagonal bottom surface of the fulcrum 230 so as to protrude substantially horizontally.

In the above configuration, the drainage tank 19 has the fulcrum 23 locked in the recess 29 of the fulcrum holder 28, and the diagonal bottom surface of the fulcrum 23 is held by the elastic body 27. Due to this condition, the drainage water was 19%
The lever 2e is the actuator 2 of the micro switch 24.
Press 5 to operate the dehumidifier. When the drain tank 19 is filled with dehumidified water, the center of gravity of the drain tank 190 moves as shown by the two-dot chain line in FIG. 3, and the drain tank 19 begins to rotate around the fulcrum 23. When the rotational force exceeds the holding force of the elastic body 27, the lever 26 is disengaged diagonally as shown by the two-dot chain line, and at the same time the lever 26 is also disengaged from the actuator 25, thereby stopping the operation of the dehumidifier. Furthermore, if the drainage tank is not installed inside the dehumidifier,
This structure is also out of operation.

As is clear from the above embodiments, the dehumidifier full water stop device according to the present invention has a handle formed in front of the upper part of the drain tank, a fulcrum near the handle, and a microswitch for detecting full water in front of the handle. A part of the lever that operates the operation circuit and a partition plate to which this microswitch is attached are provided, and an elastic body is provided to protrude from the partition plate to support the diagonal bottom of the fulcrum in the drainage basin. Since the amount of water stored is detected by moving the center of gravity of the tank, there is less loss compared to the conventional structure that detects the amount of stored water by weight. Because it is a supporting structure, the number of parts is extremely small and assembly workability is extremely good.Also, even with mass production, all parts operate in the same way, so quality can be stabilized.It has various advantages. It is.
