JPS58158436A - Stopping device for dehumidifier at full drainage - Google Patents

Abstract

PURPOSE:To stop a dehumidifier and to prevent a drainage tank from overflowing, by an arrangement wherein a float is allowed to move up and down with fluctuation of the water level in the tank and an actuating rod is moved rectilineally through a gear unit to actuate a microswitch thereby operating and stopping the dehumidifier. CONSTITUTION:In case there is no water resulting from dehumidification in a drainage tank, a float 34 occupies a position where an E ring 39 abuts against the upper surface of a lid 24, whilst an actuating rod 30 occupies a position where an E ring 37 abuts against a rib 40 forming a through-hole 31. At that time, a push piece 41 of the actuating rod 30 is brought into contact with an actuator 43 to actuate a microswitch 42 to thereby operate the dehumidifier. Whilst, when the drainage tank 19 is filled with water, the float 34 rises and the actuating rod 30 is moved back as shown by A because of threadable engagement between the gear 35 of a post 29 and worm gear 36 of the actuating rod 30. As a result, the push piece 41 is disengaged from the actuator 43 so as to stop the operation of the dehumidifier.

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, 1 is a dehumidifier main body, and inside is a compressor 2 that constitutes a refrigeration cycle. Evaporator 3. A condenser 4 is installed respectively. Reference numeral 6 uses fins to suck in air from an intake grille 6 and discharge it from an outlet grille 7. 8 is a drainage tank installed next to the compressor 2, and the dehumidified water condensed in the evaporator 3 is dripped into the water tray 9, and then from the water tray 10.
It is collected in the drainage tank 8.

The drainage tank 8 is placed on a tank pedestal 11, and the tank pedestal 11 is composed of a fulcrum 12 and a compression spring 13. As the dehumidified water in the drainage tank 8 increases, the fulcrum 12
It is configured to rotate around. Furthermore, the tank pedestal 11 has a structure in which an L-shaped lever arm 16 that is interlocked with a microswitch 14 for detecting full water is locked.
1, the actuator 16 of the microswitch 14 is pressed to operate the sludge remover. 0 Then, when the drain tank 8 becomes full, the compression spring 13 contracts and at the same time the lever arm 16 descends. 16 comes off from the actuator 16 of the microswitch 14,
Stop operating the dehumidifier.

In addition, when the drain tank 8 is removed from the dehumidifier main body 1, the micro switch 14. It has a structure in which the lever arm 16 is released from the actuator 16 of the microswitch by a tension spring 18 whose one end is fixed to a holding fitting 17 that holds the lever arm 16 and whose other end is attached to the lever arm 16.

However, the above structure requires a very large number of component parts that make up the full-water stop mechanism, resulting in high material costs.

It has the drawback that it requires a lot of manufacturing man-hours, and it also requires a lot of manufacturing time.
It was difficult to make adjustments to eliminate variations in the spring constant of the tension springs, and due to poor adjustment, there was a risk that dehumidified water would overflow into the drainage tank, wetting the room, and reducing electrical insulation.

In addition, when the water level is close to the full water stoppage level, if vibrations occur due to walking or cleaning in front of the dehumidifier, the drain tank is supported only by a compression spring, so the water level may be lowered before the water level reaches the specified water level. There were drawbacks such as the microswitch being activated.

The present invention eliminates the missing door seen in the above-mentioned conventional full-water stop device.

Hereinafter, FIGS. 2 to 2 of the accompanying drawings showing one embodiment of the present invention.
This will be explained with reference to FIG. Components that are the same as those in FIG. 1 are given the same numbers and their explanations will be omitted.

In the figure, the drainage tank 19 is installed next to the compressor 2o, and the drainage tank 19 and the compressor 20 are separated by a partition plate 21.
It is separated by The drain tank 19 is fixed by a convex portion 23 of a tank 22 and a hole 26 of a lid 24. Lid 24
The dehumidified water condensed from the evaporator 26 is transferred to the drainage tank 1.
Opening hole 27 leading to 9, through hole A through which the float support 28 passes
29. A through hole B519 and a through hole C32 through which the operating rod 3o passes are provided. A penetrating portion 33 in the tank 22 through which the operating rod 3o passes is a U-shaped notch or hole, and the penetrating portion 33 is larger than the through hole C32. A float 34 made of blow molding, foamed polystyrene, or the like is connected to the float support 29, and extends in the axial direction of the float support 29 to form a gear 36. A worm 36 extending along the bright line over the entire circumference is formed approximately at the center of the operating rod 3o, and a pusher piece 41 bent into an L-shape is formed at one end.

Here, to assemble the drain tank 19, first cover the lid 24.
Pass the operating rod 3o through the through hole B519 and the through hole C32,
E-ring A37 to prevent removal. It is fixed with an E-ring B3B, and then the float support 28 is passed through the through hole A2s and fixed with an E-ring 039.

The completed flap 24 is fixed with the hole 26 and the protrusion of the tank 22.

In the above configuration, when the drain tank 19 is installed in the dehumidifier and there is no dehumidified water in the drain tank 19, the float 34
is the position where the E-ring C39 contacts the upper surface of the flange 24, and the operating rod 30 is stopped at the position where the E-ring A37 contacts the rib 40 forming the through hole B31. At this time, the push piece 41 of the operating rod is the actuator 4 of the microswitch 42.
3 to operate the microswitch 42 and operate the dehumidifier.

Then, as shown by the two-dot chain line in Fig. 3, the drainage tank 19
When moisture-proof water collects inside, the float 34 rises to the position indicated by the dotted line, and through the action of the gear 36 of the float support 29 and the worm 36 of the operating rod 30, the operating rod 3o retreats as shown by arrow A. , the push piece 41 of the operating rod 3o is a micro switch 42
actuator 43, and the operation of the dehumidifier is stopped.

Further, when the drain tank 19 is not installed in the dehumidifier, the microswitch 42 is opened and the dehumidifier stops operating. The micro switch 42 is connected to the operating rod 3
0 is attached to the partition plate 21 at the operating position.

Therefore, the amount of dehumidified water when full water is stopped is the drainage tank 19.
Float 34 can reliably detect the water surface of
Since the movement is reliably linked to the microswitch 42, there will be no indoor water wetting due to an overflow of dehumidifying water, there will be no deterioration of electrical insulation, and there will be no malfunction due to vibration. Furthermore, it has fewer parts, is easy to install, and requires less manufacturing man-hours.
No adjustment is required and manufacturing is possible at low cost.

As is clear from the above embodiments, the dehumidifier full-water stop device according to the present invention opens and closes the dehumidifier operating circuit by operating a microswitch using a float that moves up and down depending on the level of dehumidified water in the drainage tank. Configure a dehumidifier,
A gear part is provided at the intersection of the column connected to the float and the operating rod that operates the microswitch, and this gear part changes the vertical movement of the float into left and right linear movement, and this gear part allows the operating rod to move left and right in a straight line. It's like changing,
The gear part converts the vertical movement of the float into horizontal and horizontal linear movement to operate the microswitch, so even if ripples occur on the water surface due to vibration, the microswitch will not react sensitively to this and activate the microswitch, causing a malfunction. It has various advantages, such as being able to reliably stop the water at full capacity without causing water leaks, improving the inconvenience caused by overflowing dehumidified water, and not using a single spring to detect the amount of dehumidified water, so the configuration is simple, no complicated adjustments are required, and it can be manufactured at low cost. It has the following.
