The present invention relates to a condensate drainage pump that drains condensate generated from an air conditioner to an outdoor location. More specifically, it is possible to operate a main switch and a safety switch using a single hole so that an operation error does not occur. An improved switch operating device for a condensate drain pump for an air conditioner.

In general, air condensate is inevitably generated due to temperature difference, so a separate condensate drain pump (hereinafter, also referred to as drain pump) is installed outside the air conditioner to discharge condensate from the air conditioner to the sewer or the outside. .

The condensate from the air conditioner flows into the collecting tank of the drain pump and is then discharged to the outside by the pump means with motor and impeller.

And the condensed water collected in the collecting tank is provided with a switch operating means for stopping the pump means in the low water level state and operating the pump means in the high water level state.

Switch operation means are largely divided into electronic and mechanical (mechanical) methods, and the electronic method uses electronic circuits (PCB boards), which not only has a disadvantage of causing a large cost increase but also a cost when safety switch function is added. There is a problem that causes an increase.

The present invention relates to a small drain pump having a mechanical (mechanical) switch operation means capable of lowering manufacturing costs by escaping the electronic method which has a problem in economical efficiency. In such a small mechanical drain pump, a safety switch function is provided. The reason is that the space is narrow.

The mechanical switch operation means allows the switch to be operated by using a float that floats according to the condensate level. As a prior art, Korean Utility Model Registration No. 20-0168381, Korean Utility Model Registration No. 20-0252340, Utility Model Registration No. 20-0346157 and Applicant Registration Utility Model No. 20-0396643 have been disclosed.

Since the prior arts are to operate one switch by one sub-sphere, for example, when a switch failure occurs, the pumping means cannot be operated, and condensate water overflows out of the sump member.

Therefore, by providing two sub-spheres and two switches, one is used as the main switch operating means and the other is used as the safety switch operating means so that the safety switch means can be operated when a failure occurs in the main switch operating means. A switch actuating device may be implemented, but in this case, the main switch actuating means and the safety switch actuating means should be combined with the two relatively large sub-spheres, which is not preferable for the use of a drain pump requiring a relatively small size. In addition, cost increases will weaken external competitiveness.

In addition, the above-described prior art has a structure in which one operating rod is provided on the sub-sphere to penetrate the middle of the operating piece of the switch, and a stopper member such as a snap ring is mounted on the upper and lower parts thereof. It is installed floating on the surface of the water.

Therefore, shaking occurs in the process of moving up and down the sub-sphere, resulting in interference between the switch operating piece and the working rod of the sub-body passing through the center, and at the same time moving the moving rod up and down. As movement occurs in the left and right directions, interference occurs with the switch operating piece, and thus the switch malfunctions frequently, thereby causing a problem of deterioration of the drain pump.

In addition, the switches adopt a limit switch, also called a micro switch, and the working rod of the limit switch is installed through the opening of the limit switch, and the snap ring installed on the upper and lower portions of the operating rod presses the limiting force. The switch is configured to operate.

Therefore, it has been found by the applicant that the snap ring hits the operation piece of the limit switch with a relatively strong force, which causes the life of the limit switch or the failure rate to be significantly increased, and the improvement is required.

The present invention makes it possible to operate the main switch and the safety switch by using a single sub-sphere, and at the same time, it is possible to stably float without shaking the sub-sphere, and the interference between the switch operating piece and the pressurizing rod for pressurizing it The purpose of the present invention is to provide a switch operating device for an air conditioner condensate drain pump that can be installed in a confined space, prevents malfunctions, and improves service life.

Another object of the present invention is to provide a switch actuating device for a condensate drain pump for an air conditioner that can be installed in a narrow space such as a mechanical drainage pump, and that the safety function and economy can be achieved.

The present invention for achieving the above object is an impeller is rotated by a motor power installed in the water collecting tank in which the condensed water introduced by the inlet hose is collected, and the partition member fixed to the water collecting tank, the condensed water drainage hose As having a pumping means to be discharged through; A pair of hinge brackets protruding from the bottom of the partition member support the hinge protrusions of the rear connecting pieces so that they can be rotated, and the upper part has an elongated standing piece that partially penetrates the through-hole of the partition member. A sub-sphere having a low-level high pressure protrusion wheel part protruding in the direction and protruding at a position parallel to the high-level touch protrusion wheel part on the other side; When the main switch is fixed to the support member on the upper surface of the partition member so that the tip of the touch operation piece is positioned between the low and high water level touch projections, and the touch operation piece of the main switch is pushed up by the high level touch projections and moved up. It is characterized in that it comprises a safety switch is installed so that the tip of the pressing operation piece is located in a lower position than the tip portion so that the abnormal water level pressure protrusion wheel portion can be pressed.

The main switch is a snap action switch having a contact switch for pressing and withdrawing by the touch operation piece, and the safety switch is a limit switch having a contact hole which is automatically drawn out after being pressed by the pressing operation piece. It is done.

Referring to the present invention in more detail based on the accompanying preferred embodiments as follows.

Figure 1 shows a drain pump in which the present invention is carried out, the present invention is condensed water (W) flows into the collection tank (10) by the inlet hose (1) connected to the air conditioner (not shown) to be collected. In the upper part of the collecting tank 10, the partition member 11 is fixed together with the upper cover member 15 by fixing means such as a screw (not shown).

In addition, the condensate (W) of the collection tank (10) is to be drained to the sewer or outdoor by the pumping means (20) to rotate the impeller 22 by the power of the motor 21 to be discharged through the drain hose (2). It has a configuration. Reference numeral 23 is a heat dissipation fan that cools the heat generated when the motor 21 is driven.

The outer shell member 10a of the collecting tank 10 is formed of a plastic member, and the inner shell member 10b is formed of a polystyrene paper (PSP) foam member, and has a structure in which the outer shell member 10b is closely attached to each other. Has become.

The PSP foam member, which is an inner skin member 10b, is foamed by injecting gas into a conventional PSP fabric and forms a large number of air pore layers inside the PSP foam member to provide thermal insulation.

Therefore, the cold temperature of the condensate (W) to the outside to act as a thermal insulation to block in the inner member 10b, which is a thermal insulation member made of PSP foam member, thereby causing the hot surface of the room on the outer surface of the outer member (10a) Condensation phenomenon due to contact with air is composed of a collecting tank (10) to be prevented.

On the other hand, inside the collection tank 10 is installed when the condensed water (W) is full, the subsidiary body 30 for operating the motor 21 to detect this.

As shown in FIGS. 1 and 2, the substructure 30 is rotatably supported by the hinge protrusions 32 of the rear connecting pieces 31 supported by a pair of hinge brackets 12 protruding from the bottom surface of the partition member 11. It is installed.

In addition, the upper end portion of the substructure 30 has a long standing piece portion 33 which partially passes through the through hole 13 of the partition member 11, and on one side surface of the standing piece portion 33 in the transverse direction. Thus, the low and high level touch protrusions 34 and 35 are protruded, respectively, and the other side is provided with an abnormal level pressure protrusion wheel portion 36 protruding at a position parallel to the high level touch protrusion wheel 35.

In addition, between the low and high water level touch protrusions 34 and 35, the tip of the touch operating piece 41 of the main switch 40, which is fixedly installed to the support member 14 on the upper surface of the partition member 11, is positioned.

In addition, the tip end portion of the pressing operation piece 51 of the safety switch 50, which is also fixed to the support member 14 on the upper surface of the partition member 11, is positioned so that the abnormal water level pressure protrusion wheel 36 can pressurize. However, when the touch operating piece 41 of the main switch 40 is moved by being pushed up by the high water level touch protrusion 35, the tip end portion of the pressing operation piece 51 is positioned at a position lower than the tip part so that the abnormal level pressure is applied. The safety switch 50 is configured to be installed so that the wheel portion 36 can pressurize.

In addition, the main switch 40 is a snap acton switch (switch acton switch) having a contact switch (41) for pressing and withdrawing operation by the touch operation piece 41 is used, the snap action switch ( When only a pressing force in a state of slightly touching 41) is a type of switch in which the touch operating piece 41 moves up or down by itself, it is a known switch, and thus detailed detailed internal drawings and descriptions are omitted. Only relevant explanations will be given.

3 shows when the condensate (W) is in the low water level (Sa) state in the water collecting tank (10) of the device of the present invention, when the condensate (W) is introduced through the inlet hose (1) in this state, the water level gradually rises. And thereby the float 30 is gradually raised by buoyancy.

At this time, as the spherical body 30 is raised in a state in which the hinge bracket 12 is rotated around the hinge protrusion 32, the spherical body 30 moves upwardly without shaking in the left and right directions. Will be.

Therefore, as the substructure 30 is shaken in the left and right directions, the touch operation piece 41 or the pressing operation piece 51 of the main switch 40 and the safety switch 50 are incorrectly touched so that no malfunction occurs. And accurate operation is achieved.

Therefore, when the condensed water (W) is gradually filled to reach the high water level (Sb) state, as shown by the virtual line in FIG. 4, the high water level touch wheel part 35 moves the touch operating piece 41 of the main switch 40. It is in a state of pushing a little, whereby the touch operating piece 41 is instantaneously automatically raised and operated to move up like a solid line.

In this way, the touch operation piece 41 is instantaneously automatically lifted up and moved to move up as shown in the solid line by using a snap action switch on the main switch 40. The known snap action switch itself is It is manufactured together.

Therefore, when the high water level touch projection portion 35 is in a state of slightly pushing the touch operation portion 41 when the high water level Sb state is raised, the touch operation portion 41 is automatically raised instantaneously. By not pressing the touch operation piece 41 unreasonably, the failure occurrence rate of the main switch 40, which should be frequently operated for a long time, is remarkably reduced and the service life is increased.

On the other hand, the high water level (Sb) state and the high water level touch projection portion 35 is in a state of slightly pushing the touch operation piece 41, the instantaneous contact switching port 41 is instantaneously raised automatically the touch operation piece (41) As it enters into a stopped state and enters the power supply to the motor 21, the entire pumping means 20 including the motor 21 is operated to discharge the condensate water W to the drain hose 2. Will be.

Therefore, the condensed water (W) of the collecting tank 10 is in a state where the water level is gradually lowered again to a low water level (Sa) state as shown in FIG. 3, and as a result, the substructure 30 is gradually lowered as shown in the virtual line. As described above, the low water level touch wheel portion 34 is in a state of pushing the touch operation piece 41 downward.

As described above, when the low water level touch wheel part 34 pushes the touch operation piece 41 downward, the touch operation piece 41 automatically descends slightly as shown in the solid line as described above. Therefore, the pumping means including the motor 21 is in a state in which the power supply to the motor 21 is cut off from the main switch 40 while the contact point switching port 41 is drawn out to the outside. 20, the whole operation is stopped and the condensate (W) drainage action discharged to the drain hose (2) is stopped, the device of the present invention, as described above, the condensate (W) is filled in the collecting tank (10) again When the high water level (Sb) is a drainage action and the low water level (Sa) due to the drainage action is repeated.

On the other hand, even if the main switch 40 is broken or high power (Sb) due to various factors, the power is not supplied to the motor 21, so the water level of the condensate (W) gradually rises, as shown in FIG. In the case of Sc), as the substructure 30 is raised, the abnormal water level pressure protrusion wheel part 36 is pressed in a state of pushing the pressing operation piece 51 of the safety switch 50.

Therefore, as the contact hole 52 enters the inside, the safety switch 50 is operated to supply power to the motor 21, and the pumping means 20 is operated to drain the condensed water. (W) does not overflow outside the collection tank 10 and at the same time the external emergency indicator lamp (not shown) is turned on or the buzzer device (not shown) notifies the outside that the drainage pump is in a broken state. Repair or replacement will be possible.

That is, when the safety switch 50 is operated can be drained by operating the motor 21, in some cases the safety switch 50 is connected to the low voltage circuit of the air conditioner (not shown) abnormal water level By stopping the compressor (not shown) of the air conditioner at the time of occurrence, it is possible to prevent further condensate from being generated from the air conditioner, thereby preventing the condensate from being collected toward the drainage pump. You can also make it ring.

In addition, the safety switch 50 is a limit switch which is automatically drawn out when the pressing force is lost after the contact port 52 is pressed by the pressing operation piece 51, such a limit switch is adopted Since the parts are already known, internal drawings and descriptions are omitted.

Therefore, since the safety switch 50 employing the limit switch is operated only once in an emergency, there is no great force even if an excessive force is applied to the pressing operation piece 51.

Therefore, the present invention is that the safety switch 50 is operated when the abnormality occurs in the high water level (Sb) state, as shown in Figure 5a and 5b, the touch operation piece 41 of the main switch 40 is a high-level touch stone After moving up by the wheel part 35, the abnormal water level pressure protrusion wheel part 36 presses the pressing operation piece 51. As shown in FIG.

Therefore, after the high water level touch protrusion part 35 pushes the touch operation piece 41 and the touch protrusion wheel part 35 is automatically raised, the abnormal water level pressure protrusion wheel part 36 presses the pressure operation piece 51.

In this state, the high water level touch wheel portion 35 has a distance h 'smaller than the distance h of the abnormal pressure pushing wheel portion 36 and the pressing operation piece 51 than the distance h of the touch operating piece 41. have.

Therefore, even if the abnormal level pressure protrusion wheel part 36 presses the pressing operation piece 51, the high level touch protrusion wheel part 35 does not reach the touch operation piece 41.

That is, when the touch operation piece 41 of the main switch 40 is moved upward, the tip end portion of the pressurizing operation piece 51 is positioned at a position lower than the tip part so that the abnormal water level pressure protrusion wheel part 36 can pressurize. Thus, the abnormal water level pressure protrusion wheel part 36 can press the pressing operation piece 51 without interference at the time of the abnormal water level Sc.

As such, the present invention is characterized in that the main switch 40 for supplying and cutting off the power to the motor 21 by one substructure 30 and the safety switch 50 can be operated in an emergency. Compared with other conventional drainage pumps, it is possible to install in a narrow space and to achieve a large discharge amount, thereby improving product function.

In addition, since the float 30 is moved up and down only in the up and down directions without shaking left and right, accurate operation is promoted due to a stable operation, so that there is no error operation of the drainage pump and quality is improved.

And the main switch 40 is a snap action switch having a contact switch (41) for pressing and withdrawing operation by the touch operating piece 41 is employed and the safety switch 50 is pressed by the pressing operation piece (51) By adopting the limit switch having a contact hole 52 which is automatically drawn out after being applied, excessive force is not applied to the touch operating piece 41 of the main switch 40, which should be operated from time to time, thus preventing error operation in advance and increasing service life. This will greatly contribute to the quality improvement of the drain pump.

In addition, since the safety function can be installed in a small space of a small drain pump having a mechanical switch operating means, the safety and economical efficiency can be achieved, and the drain pump can be miniaturized.

According to the above description, the present invention enables the main switch and the safety switch to be operated using a single spherical body, thereby providing an effect that can be installed even in a narrow space, and at the same time, ensuring reliable operation of the spherical body, thereby preventing error operation. There is an effect of providing a condensate drainage pump which does not cause malfunction and increases life by preventing interference between the switch operation piece and the protrusion wheel to operate by pressing the switch.

In addition, it is a useful design having the effect of providing a condensate drain pump for an air conditioner that can be installed in a narrow space, such as a mechanical drainage pump, while ensuring safety functions and economy.
