Description

Heat-Resistant Drain Pump System for Air Conditioning Unit

The present invention relates to a drain pump system for an air conditioning device with enhanced heat resistance, and more particularly, to a drain pump system for an air conditioning device with enhanced heat resistance designed to stably receive and discharge condensate or humidified water generated in an air conditioning device operating in a high temperature and high humidity environment.

Air conditioning units operate in a variety of environments to control indoor temperature and humidity, generating large amounts of condensate or humidifying water during this process. This moisture must be collected at the bottom of the system and discharged. A drain pump system is typically used for this purpose.

Conventional drain pump systems are mostly comprised of plastic tanks and pipes. They are sensitive to temperature changes and often experience durability issues with long-term use. In particular, they frequently break due to repeated thermal expansion and contraction in high-temperature environments, and corrosion problems caused by impurities contained in the internal condensate frequently occur.

Additionally, typical drain pumps are either manually operated or rely on simple timers or electronic level sensors, which can lead to over-draining or malfunctions.

Due to the limited installation space within the air conditioner, it may be difficult to connect pipes, and if backflow or failure occurs during condensate discharge, it may not only lead to a decrease in the performance of the device but also lead to hygiene issues.

Therefore, there is an urgent need to develop technology that can maintain structural stability and emission performance even in high-temperature and humid operating environments, while ensuring installation flexibility along with an automated control system.

Meanwhile, the background technology described above is technical information that the inventor possessed for the purpose of deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the application for the present invention.

According to one aspect of the present invention described above, durability and lifespan can be dramatically improved by applying a high-heat-resistant tank made of SUS material so that it can be operated stably without corrosion or structural damage even in high-temperature and high-humidity environments.

In addition, since water tightness and mechanical strength are maintained even during long-term storage of condensate, it can provide a configuration suitable for air conditioning systems requiring long-term operation.

Since the inlet pipe is bent in an “ㄱ” shape, it is easy to install even in the limited space of the air conditioner, and the U-Trap function is implemented to block the inflow of external odors or air.

The L-shaped inlet pipe (200) is configured to introduce condensate or humidifying water from the air conditioning unit (1) into the SUS tank (100).

This L-shaped inlet pipe (200) is formed with a structure bent in the shape of the letter “L”, so that it can be placed appropriately in the internal or external structure of an air conditioning unit with limited installation space.

In addition, the bending angle and pipe diameter can be optimized to prevent abrupt drops or swirling flows from occurring in the inflow path, so that smooth gravity flow or pressure-conveyed inflow of condensate can be achieved.

The inner surface of the pipe is polished to minimize contaminants and moisture residue, and is made of stainless steel to ensure heat resistance and corrosion resistance.

This L-shaped inlet pipe (200) is formed with a structure bent in the shape of the letter “L”, so that it can be placed appropriately in the internal or external structure of an air conditioning device with limited installation space.

An outlet is formed in the vertical part of the inlet pipe, and this vertical part is installed to be filled with condensate or humidifying water contained in the air conditioner (1), thereby performing the U-Trap function.

In addition, the bending angle and pipe diameter can be optimized to prevent abrupt drops or swirling flows from occurring in the inflow path, so that smooth gravity flow or pressure-conveyed inflow of condensate can be achieved.

The inner surface of the pipe is polished to minimize contaminants and moisture residue, and is made of stainless steel to ensure heat resistance and corrosion resistance.

The discharge pump (300) is configured to stably discharge condensate or humidifying water contained in the SUS tank (100) to the outside.

This discharge pump (300) is configured with a motor and casing suitable for an air conditioning environment requiring heat and moisture resistance, and is designed to enable stable operation even under conditions where high temperatures or humidity occur repeatedly.

The pump is driven by an automatic water level sensor, enabling automatic water level management by automatically operating and discharging condensate when the water level exceeds a set level.

Additionally, the pump's discharge line is connected to a shut-off valve or a check valve to prevent malfunctions due to backflow or poor discharge.

The discharge pump (300) is configured to stably discharge condensate or humidifying water contained in the SUS tank (100) to the outside.

This discharge pump (300) is designed to ensure stable operation in various operating environments where an air conditioning unit is installed, by being composed of a motor with enhanced heat and moisture resistance and a sealed casing to ensure durability and reliability even in high temperature and high humidity environments.

This discharge pump (300) is designed to ensure stable operation in various operating environments where an air conditioning unit is installed, by being composed of a motor with enhanced heat and moisture resistance and a sealed casing to ensure durability and reliability even in high temperature and high humidity environments.

In particular, it is manufactured with high output to enable smooth drainage without any restrictions on the installation location, and can efficiently transport condensate regardless of the height difference or distance of the drainage pipe.

In addition, the discharge pump (300) is equipped with a control algorithm designed to optimize the operating conditions of the pump according to temperature changes in the condensate or humidifying water.

This control algorithm senses the temperature of the incoming condensate and adjusts the pump's rotation speed, pressure, and operating time in real time even under conditions where the viscosity changes, thereby preventing pump overload and maintaining optimal energy efficiency.

This control function allows for flexible response to changing heating and cooling modes depending on the season, or environments where condensate characteristics change depending on outside temperature changes, thereby extending the life of the equipment and reducing maintenance costs.

The pump is driven by an automatic water level sensor, and automatically operates to discharge condensate when the water level exceeds the set level. A blocking valve or a check valve is installed in the discharge line to prevent backflow in the discharge path or failure due to reverse rotation of the pump.

A drain pump system (10) for an air conditioning device with enhanced heat resistance according to one embodiment of the present invention having the configuration described above can stably receive and discharge condensate or humidified water generated in the air conditioning device, thereby maintaining durability even in high temperature and high humidity environments and providing the effect of long-term uninterrupted operation.

In particular, it has the technical effect of being resistant to corrosion and thermal deformation by applying SUS material, increasing installation convenience through the “ㄱ” shaped pipe structure, and enabling stable discharge management without user intervention through the automatic pump drive system.

A drain pump system (10) for an air conditioning device with enhanced heat resistance according to one embodiment of the present invention having a configuration as described above may further include a floating water level sensor (400).

The floating water level sensor (400) is configured to control the discharge pump (300) to automatically operate when the water level of condensate or humidifying water reaches a certain standard, thereby accurately determining the discharge time, thereby preventing unnecessary pump operation and contributing to improving energy efficiency.

The floating sensor naturally moves up and down due to buoyancy according to the liquid level in the tank, and generates a driving signal for the motor through a switching structure linked to it.

Accordingly, when the water level inside the tank reaches a predetermined reference line, the discharge pump (300) is automatically started to discharge the condensate to the outside, and when the water level drops below the reference line after discharge, the circulation control is possible to automatically stop operation.

This structure enables automation of the air conditioning unit's water discharge system without artificial control, thereby enhancing operational convenience and safety.

FIG. 3 is a schematic diagram illustrating a configuration of a drain pump system for an air conditioning device with enhanced heat resistance according to another embodiment of the present invention.

Referring to FIG. 3, a drain pump system (20) for an air conditioning device with enhanced heat resistance according to another embodiment of the present invention includes a SUS tank (100), an L-shaped inlet pipe (200), a discharge pump (300), and a tank cleaning module (500).

Here, the SUS tank (100), L-shaped inlet pipe (200), and discharge pump (300) are the same as the components of Fig. 1, so their descriptions are omitted to avoid duplication of explanation.

The tank cleaning module (500) is configured to remove foreign substances attached to the inner wall of the SUS tank (100).

The tank cleaning module (500) is designed to periodically remove sludge or debris, etc., that are attached to the inner wall of a cylindrical SUS tank (100) due to dust, fine contaminant particles, or microorganisms contained in condensate or humidifying water generated during operation.

This tank cleaning module (500) can be implemented in various forms, such as a brush rotation method, a high-pressure water spray method, or a vibration cleaning method, and is linked to a control unit so that it can be automatically operated at the end of the periodic operation of the air conditioner or when the water level falls below a certain level.

In addition, the cleaning module (500) has a range of motion adjusted so that it can uniformly contact the entire inner wall of the tank according to the shape and curved structure of the SUS tank (100), and is made of a material with heat resistance and corrosion resistance, so that it can be used for a long time without wear or corrosion even in high temperature and high humidity environments.

Depending on the need, a cleaning solution spray function or an automatic cleaning cycle setting function can be added to minimize maintenance manpower and enable the operation of a hygienic condensate discharge system.

A drain pump system (20) for an air conditioner with enhanced heat resistance according to another embodiment of the present invention having the configuration described above can prevent contamination by residues of condensate or humidifying water generated in an air conditioner by using a tank cleaning module (500), improve the hygiene and reliability of the drain pump system, and contribute to improving maintenance efficiency.

Figures 4 and 5 are drawings showing the specific configuration of the tank cleaning module of Figure 3.

Referring to FIG. 4 and FIG. 4A, the tank cleaning module (500) includes a vertical cylinder (510), a rotation drive motor (520), a rotation plate (530), a support (540), and a plurality of inner wall cleaning parts (550).

The vertical cylinder (510) is configured to be installed upright on the inner upper side of the SUS tank (100) and can be driven to expand and contract in the up and down direction.

This vertical cylinder (510) includes an internal piston and a rod, and provides an operating force to enable the entire cleaner to rise and fall along the inner wall of the SUS tank (100) by repeatedly performing a linear motion within a set section.

This vertical drive allows removal of foreign matter across the entire height of the tank, thereby extending the range of cleaning effectiveness.

The rotary drive motor (520) is fixedly installed at the bottom of the vertical cylinder (510) and is configured to provide rotary drive force.

This rotary drive motor (520) is configured as a small high-torque type and is operated by an electric signal to rotate the drive shaft at a constant speed, thereby enabling stable and uniform rotation of the rotary plate (530).

The rotating plate (530) is a disk-shaped configuration that is installed in a shaft-coupled manner on the drive shaft of the rotating drive motor (520) and rotates.

This rotating plate (530) is designed with a structure that takes into account the center of load so as to maintain balanced rotation, and minimizes vibration generated during rotation to induce stable operation of the inner wall cleaner.

The support (540) is configured such that a plurality of support members are installed radially along the circumference of the rotating plate (530).

This support (540) is formed of a material with high rigidity and transmits the rotational motion of the rotation plate (530) toward the inner wall of the tank, thereby keeping each cleaning part in stable contact with the inner wall.

The radial arrangement evenly distributes the cleaning area, ensuring that the entire tank is cleaned without any gaps.

A plurality of inner wall cleaning parts (550) are configured to be rotatably installed at the end of each support (540) and perform cleaning by moving up and down in a close contact along the inner wall of the SUS tank (100).

Each inner wall cleaner (550) is configured in the form of a brush or pad, and removes foreign substances by rubbing along the inner wall when moving up and down, and receives centrifugal force along with the rotation of the rotating plate to maintain uniform contact pressure.

This effectively removes attached foreign substances, while also ensuring consistency and repeatability of cleaning.

A tank cleaning module (500) according to one embodiment of the present invention having the configuration described above can automatically clean the entire inner wall of a SUS tank through a precise combination of driving mechanisms, thereby providing an effect of dramatically improving hygiene and convenience of maintenance even in a high-temperature and humid air-conditioned driving environment.

Figures 6 to 8 are drawings showing the specific configuration of the inner wall cleaning unit of Figure 5.

Referring to FIGS. 6 to 8, the inner wall cleaning unit (550) includes a support unit (551), an extension unit (552), a unit connecting portion (553), a unit cover (554), a drive shaft (555), a shaft drive motor (556), a first rotation induction magnet (557), and a second rotation induction magnet (558).

The support unit (551) is configured to be rotatable by a rotational driving device installed at the end of the support (540).

This support unit (551) serves as the overall rotation center of the inner wall cleaner (550) and is responsible for transmitting driving force and supporting the structure at the same time.

Through linkage with the rotary drive device, the rotational motion of the drive shaft (555) is transmitted to the entire support unit, and becomes the starting point of the cleaning motion that rotates along the inner wall.

The extension unit (552) is composed of a plurality of members spaced apart from the support unit (551) at regular intervals while drawing an arc.

This extension unit (552) is formed of a material that is flexible and has constant elasticity, and is designed to adhere closely to the inner wall along the curved shape of the SUS tank (100).

Accordingly, the cleaning effect is evenly distributed even when rotating or rising, and consistent adhesion and friction are provided to the entire tank wall.

The unit connecting portion (553) is installed between a plurality of extension units (552) and is configured to support and interconnect them.

The unit connecting portion (553) prevents displacement between extension units and maintains structural integrity, and absorbs vibration and shaking during rotation to ensure stable operation.

The unit cover (554) is installed to cover the circumference of each of the plurality of extension units (552) and serves to remove foreign substances attached to the inner wall of the SUS tank (100) while rotating.

This unit cover (554) can be formed with a polishing brush, rubber pad, or sponge structure, and can effectively remove contaminants, mold, sludge, etc. attached to the inner wall through frictional contact.

The drive shafts (555) are arranged in a circular shape with a plurality of drive shafts interconnected by universal joints, and each drive shaft is installed while penetrating the support unit (551).

This drive shaft (555) is a key structure that distributes and transmits rotational power to the entire inner wall cleaner, and evenly distributes the rotational power of the shaft drive motor (556) throughout the structure.

The shaft drive motor (556) is configured to be installed in the support unit (551) and rotate the drive shaft (555) closest to the support unit (551).

This motor is capable of high-precision operation and can be designed with a sealed, waterproof structure to ensure stable rotation even in the tank's internal environment.

The first rotation induction magnet (557) is configured such that a plurality of them are installed at regular intervals along the circumference of the driving shaft (555).

This magnet creates a magnetic field when it rotates, and evenly distributes the magnetic field required to induce rotation.

A plurality of second rotation induction magnets (558) are installed along the unit cover (554) while forming an opposite polarity to the first rotation induction magnet (557).

This second magnet (558) is positioned opposite to the first rotation induction magnet (557), and as it rotates together with the drive shaft (555), it induces synchronous rotation of the unit cover (554) through magnetic induction.

Accordingly, rotation of the unit cover is possible without a separate physical connection, simplifying the structure and improving durability and maintenance efficiency.

An inner wall cleaning unit (550) according to one embodiment of the present invention having a configuration as described above can autonomously and effectively clean the entire inner wall of a SUS tank through a composite mechanism in which a support and rotation induction structure are combined, and provides a technical effect in which power transmission efficiency and stability can be improved simultaneously by having a plurality of rotating bodies rotate synchronously in a magnetic induction manner.

Figure 9 is a drawing showing the unit connection of Figure 6.

Referring to FIG. 9, the unit connecting portion (553) includes a rubber cover (5531), a magnet installation groove (5532), a first angle adjustment electromagnet (5533), and a second angle adjustment electromagnet (5534).

The rubber cover (5531) is made of a soft cylindrical tube shape and is installed between two adjacent extension units (552).

This rubber cover (5531) is formed of a flexible, elastic material and acts as a sealing protective film that protects the universal joint from the outside while simultaneously blocking the inflow of foreign substances.

Additionally, it can mechanically absorb changes in alignment or folding angle while maintaining structural flexibility between units, thereby extending the life of the connecting part during cleaning operations.

The magnet installation groove (5532) is a groove structure formed on the inward surface of the rubber cover (5531) and is designed to be naturally exposed in the direction of contraction when two adjacent extension units (552) are folded.

This magnet installation groove (5532) is a structure for fixing the position of the electromagnet component inserted inside the rubber cover, so that the electromagnet is stably maintained in the set position and precise angle adjustment operation is possible.

The first angle adjustment electromagnet (5533) is installed on one side of the magnet installation home (5532) and is configured to have its polarity switched through electrical switching.

This first electromagnet (5533) is converted into a N pole or S pole according to an electrical signal input from the control circuit, and can induce angle adjustment between the units through polarity interaction with the second electromagnet.

The second angle-adjusting electromagnet (5534) is installed on the other side of the magnet installation groove (5532) and has a configuration in which the polarity is switched according to electrical switching, similar to the first electromagnet (5533).

When the first electromagnet (5533) and the second electromagnet (5534) form the same polarity, they generate a repulsive force against each other, thereby pushing the two adjacent extension units (552) outward and inducing them to unfold in a straight line.

On the other hand, when two electromagnets form opposite polarities, they are attracted to each other by force, causing the extension units (552) to be folded at an angle to each other.

This method of controlling the polarity between electromagnets has the advantage of allowing flexible adjustment of the angle of the unit arrangement with only a simple electrical signal without a mechanical drive device, and can maximize structural adaptability and efficiency during the inner wall cleaning operation.

The unit connecting portion (553) according to one embodiment of the present invention having the configuration described above simultaneously secures structural continuity and operational flexibility between extension units, thereby enabling the entire unit to flexibly respond along the inner wall curve of the tank during cleaning, and provides a technical effect of actively securing the cleaning range and contact stability through an angle adjustment function based on electrical control.
