Description

[Detailed description of the invention] The present invention relates to a condensed water treatment device in which condensed water generated in an evaporator of an air conditioner such as a condenser or room cooler is collected in a drainage bucket and then treated as wastewater. be.

In general, portable air conditioners, dehumidifiers, and the like are often configured to use drainage packets to store condensed water in order to treat condensed water in the refrigeration cycle. These drainage bucket structures are designed to automatically stop operation when the drainage bucket becomes full to prevent condensed water from overflowing. In many conventional structures, a micro switch is placed on the underside or bottom of the drain bucket, and when the drain bucket becomes full, the weight of the water activates the micro switch to stop the operation of the refrigeration cycle. When you take out the drain bucket and drain the water, the operation restarts and condensed water drips even though the drain bucket is not inside the air conditioner, wetting the floor or causing negative effects on electrical connections, etc. There was a drawback.

Also, depending on the amount of water stored, in models equipped with a so-called balanced type drainage bucket, which operates a micro switch by tilting the drainage bucket around the drainage bucket fulcrum, it cannot be operated unless the drainage bucket is inserted into the air conditioner. However, even with this structure, if the fulcrum of the drainage bucket for balance and the fulcrum installed inside the equipment are not placed in the normal and proper position, it may not operate or may not operate. Even when the drain bucket is full, operation may not stop, resulting in wet floor surfaces or faulty electrical connections.

This invention eliminates the drawbacks of conventional air conditioners that use a balanced type drainage bucket.
This allows for normal operation without getting the floor wet or electrical connections wet and causing electrical leakage.

For this purpose, the present invention comprises an air conditioner in which a drain bucket that receives and stores condensed water generated in a refrigeration cycle is supported so as to be tilted according to the amount of condensed water stored. A fulcrum is provided at the bottom of the air conditioner that protrudes by a length equivalent to the width of the drainage bucket inside the air conditioner, and is fitted to the fulcrum at a position offset from the center in one direction forward and backward in the depth direction of the bottom of the drainage bucket. A concave portion is formed in the concave portion, a convex portion perpendicular to the concave portion is formed at an offset position in the width direction of the concave portion, and a concave portion that fits with the convex portion is formed at the fulcrum, and the inclination of the drainage bucket is A lever arm is provided at the position where the drain bucket is activated, and the lever arm is linked to turn on the operation of the refrigeration cycle when the drain bucket is present.
A micro switch is provided to turn off the operation of the refrigeration cycle when the drain bucket is tilted or when the drain bucket is removed.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a main body of an air conditioner or the like, which houses a compressor 2, an evaporator 3, and a condenser 4, thereby forming a refrigeration cycle within the main body 1. Reference numeral 5 denotes a fan, which is installed in the upper part of the main body 1.
6 is an intake grill formed on the main body 1, and 7 is an outlet grill from which air is discharged. 8 is the bottom board of the main body 1, and the compressor 2 is the bottom board 8.
supported above. A drain bucket 9 stores condensed water flowing down from the evaporator 3 through a water tray 3', and is installed immediately next to the compressor 2. The drainage bucket 9 is supported by an upwardly protruding fulcrum 10 fixed to a bottom substrate 8, and this fulcrum 10 is fitted into a recess 11 provided in a strip shape on the bottom surface of the drainage bucket 9. Here, the fulcrum 1
0 and the recess 11 are formed at positions slightly offset in one direction from the center of the drainage bucket 9, and are configured so that the drainage bucket 9 cannot be installed if the front and back directions of the drainage bucket 9 are incorrect. 12 is a balancer such as an iron plate fixed to the drain bucket 9 with screws 13. The inside of the drainage bucket 9 is divided by a partition wall 15 into a chamber A 14 on the side where the balancer 12 is attached and a chamber B 16 on the opposite side.

A lever arm 17 is in contact with the bottom surface on the side of the A chamber 14, and the lever arm 17 has a structure in which a micro switch 18 is operated at the other end. If the drain bucket 9 is not inside the main body 1, press the micro switch 1.
8 is in the OFF state, and the operation of the refrigeration cycle has stopped. Insert the drainage bucket 9 into the main body 1,
When the A chamber 14 side is aligned with the lever arm 17 side and the fulcrum 10 and the recess 11 are aligned, the micro switch 18 is turned on and the refrigeration cycle starts operating. The fulcrum 10 is provided with a plurality of recesses 19. A plurality of convex portions 20 that fit into the concave portion 19 form the concave portion 1 at the bottom of the drainage bucket 9.
1. Reference numeral 21 denotes a lid on which a carrying handle 22, which fits into the drainage bucket, is simultaneously molded. Here, the positions of the recess 19 and the protrusion 20 are provided at positions offset from the center of the drain bucket 9, respectively, so that, like the fulcrum 10 and the recess 11, the drain bucket 9 cannot be installed in the wrong front-back direction. It is configured.

In the above configuration, the operation will be explained next. When the refrigeration cycle operates, the condensed water from the evaporator 3 first accumulates in the A chamber 14, and when the A chamber becomes full, it overflows from the upper end 23 of the partition wall 15 and flows into the B chamber 14. It starts to accumulate. When the weight accumulated in the B chamber 16 becomes greater than the weight of the condensed water accumulated in the A chamber 14 plus the weight of the balancer 12, the drain bucket 9 falls to the B chamber 16 side, and the lever The arm 17 is separated from the bottom of the drain bucket 9, and the micro switch 18 is turned OFF, resulting in a balanced structure in which the operation of the refrigeration cycle is stopped.

With the above structure, the convex part 20 provided in the concave part 11 on the bottom of the drain bucket 9 and the concave part 19 provided in the fulcrum 10 fit together, so that the drain bucket 9 is reliably placed in the normal position. Because it is installed,
Operation is turned on and off reliably.

If the convex portion 20 and the concave portion 19 are not present, the drain bucket 9 may move from side to side, and the lever arm 17 may not come into contact with the bottom of the drain bucket 9, causing the operation to not start. However, in this embodiment, No such problem arises.

Further, when only one protrusion 20 and one recess 19 are provided, the protrusion 20 should not be provided at the center of the bottom recess 11 of the drainage bucket 9, but may be placed slightly away from the center. This is because when the drain bucket 9 is inserted into the main body 1 with the front and back upside down, the protrusion 20 does not fit into the recess 19 of the fulcrum 10, so the protruding fulcrum 10 and the protrusion 20 come into contact with each other.
Since the drain bucket 9 is tilted in a more floating state than usual and further tilted toward the front, the lever arm 17 is not actuated, so the refrigeration cycle operation is not performed and the user knows that it was inserted in the reverse direction. or,
If there are multiple protrusions 20, one may be placed at the center of the recess 11, but the protrusions 20 may not be equally spaced, or there may be a plurality of protrusions 2 only on one side from the center.
Providing 0 also has the same effect as preventing erroneous insertion described above.

In addition, in this embodiment, the recess 11 is the drainage bucket 9.
It is formed at a position close to the balancer 12 side on the bottom surface of the balancer 12. Therefore, among the A and B2 chambers 14 and 16 separated by a partition wall rising from the recess 11, the A chamber 14 has a smaller volume than the B chamber 16. As a result, when a considerable amount of water accumulates on the B chamber 16 side, the B chamber side becomes heavier than the full A chamber side, and the drainage bucket 9 is moved to the B chamber side with the fulcrum 10 as the center.

As described above, the present invention has the following features:
A fulcrum is provided at the bottom of the air conditioner, and a concave and convex portion of the drain bucket that fits into a concave provided perpendicular to the fulcrum is provided, and each concave and convex portion is connected in one direction from the center of the drain bucket. If the drainage bucket is installed in the wrong direction, the installation condition of the drainage bucket will become unstable, so the user can easily confirm the incorrect condition and reliably prevent use in the incorrect condition. be done. As a result, the tilting operation of the drain bucket becomes reliable, and the operation of the refrigeration cycle by opening and closing the switch becomes reliable.
This has the effect of preventing accidents such as overflow of condensed water due to continuous operation of the refrigeration cycle due to misuse, damage to the floor surface, and electrical leakage caused by this.
