Abstract
Description
[0001] DESCRIPTION
[0002] Drainage system with electric stop and warning for air conditioning
[0003] OBJECT OF THE INVENTION
[0004] The invention, as the title of this specification indicates, is a drainage system with an electrical alert for air conditioning units to prevent water overflow. It is an innovation that offers advantages previously unknown within current technologies.
[0005] TECHNICAL SECTOR
[0006] The present invention falls within the field of mechanics, especially in heating, air conditioning and ventilation, and in the classification of air conditioning.
[0007] STATE OF THE ART
[0008] The present invention arises because the water generated by the condensation of the air conditioner, without an adequate drainage system, causes overflows and associated damage if you are not attentive when the reservoir fills up.
[0009] When installing an air conditioner in locations without pre-existing plumbing, it is essential to place a container to collect the condensation. However, this comes with the problem that if the container is forgotten, it can overflow and cause damage to the home or to neighbors.
[0010] Accordingly, this invention provides an electrical warning system that would stop the air conditioner, preventing the nuisance and risk of water overflowing and causing damage to the home, neighbors, or anywhere else the container is located.
[0011] Currently, there is no known existence of any drainage system with an electrical warning that automatically stops the air conditioning that has structural and constitutive technical characteristics equal or similar to those described in this descriptive report, as claimed.
[0012] DESCRIPTION OF THE INVENTION
[0013] 2 The object of the present invention is the creation of a drainage system with electric warning for air conditioning that provides a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany this description.
[0014] The present invention relates to an electrically alerted drainage system for air conditioners. It comprises a container mounted on a support and connected to the condensate drain of an air conditioner and an electrical system that automatically shuts down the air conditioner, preventing it from restarting until the container is empty. The electrical system emits an alert to empty the container, thus preventing overflow. For this purpose, it includes a direct or indirect level sensor.
[0015] This system is beneficial because it is practical, as it prevents water overflows in air conditioners, improving the safety and comfort of users.
[0016] The electrical indicator for air conditioning is characterized by a container that, for example, is a jug with a large capacity to collect the fluid generated by the condensation of the air conditioner.
[0017] The system support is an open box that has a base with vertical rods and transverse rods.
[0018] The container is placed inside the support, which has a microswitch connected to the electrical system.
[0019] The microswitch is located at the bottom of the support and is a switch of the NC (normally closed) and NO (normally open) type, activating when the container resting on the switch is filled.
[0020] Furthermore, the electrical system is housed in a junction box attached to the support and includes the wiring that connects the microswitch to a power supply, as well as an audible and / or visual alarm, among other components. Additionally, the container may be equipped with a level sensor that, upon detecting maximum fill with condensation fluid, activates the switch to allow the container to be emptied.
[0021] Likewise, the switch is associated with a spring located under the container which, when filled by its weight, which implies that a liquid level has been reached in the container, activates the microswitch and this, being connected to the start / stop of the split, would stop it automatically.
[0022] Finally, the power supply consists of at least one long-life rechargeable battery, which ensures the operation of the drainage system with electrical alert for air conditioning.
[0023] To use the electrically alerted air conditioner drain system, first place the container inside the holder and connect it to the air conditioner's condensate drain.
[0024] The electrical system must be connected, ensuring that the switch and level sensor are correctly installed.
[0025] During operation, the container will collect the condensation water and, when it is full, the switch will automatically stop the air conditioner.
[0026] EXPLANATION OF THE FIGURES
[0027] To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by a figure in which, for illustrative and non-limiting purposes, the following has been represented.
[0028] Figure 1 shows a perspective view of the drainage system with electrical alert for air conditioning.
[0029] PREFERRED EMBODIMENT OF THE INVENTION.
[0030] The present invention consists of an electrically alarmed drainage system for air conditioning, characterized by comprising a container (1) that rests on a support (2) and is connected to the condensate drain (3) of an air conditioning unit. This system includes an electrical system (4) that emits an alarm and shuts down the air conditioning unit, preventing overflow when it detects that the internal level has reached a preset value. This level can be detected directly, for example, by a sensor system, such as one that detects weight, or by a spring and a microswitch.
[0031] In a preferred embodiment, the drainage container is a jerrycan with a stand, the jerrycan having ample capacity to collect the fluid generated by the condensation of the air conditioner with a junction box connected to the micro switch.
[0032] In another preferred embodiment, the support (2) is an open box having a base (2.1) with vertical rods (2.2) and transverse rods (2.3). The support would operate with a level sensor similar to those used in wells or tanks.
[0033] Typically, the container (1) is located inside the support (2), which is equipped with a switch (5) connected to the electrical system (4). This switch (5) is located at the bottom of the support (2) and is of the NC (normally closed) and NO (normally open) type, activating when the container (1) resting on said switch (5) is filled, which implies that the weight, and the level, has reached the preset value.
[0034] Generally, the electrical system (4) is housed in a junction box (6) attached to the support (2) and includes the wiring that connects the switch (5) to a power supply (7) and an audible and / or visual warning device (8), among other components. The warning device (8) can also be a notification to a home automation control unit or a mobile phone application.
[0035] In another embodiment, the container (1) has a level sensor that, upon detecting maximum filling with condensation fluid, activates the switch (5) to allow the container (1) to be emptied. Activation can occur when the container (1) is 10-15% full, giving the user time to access it.
[0036] In another preferred embodiment, the switch (5) is associated with a spring located beneath the container (1). When the container is filled by its weight, the spring activates the switch (5), which in turn activates the warning device (8). Generally, the power supply (7) is at least a long-life rechargeable battery, which ensures the operation of the electrically alarmed drainage system for air conditioning.
[0037] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field may understand its scope and the advantages that derive from it, it being noted that, within its essentiality, it may be put into practice in other modes of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought provided that its fundamental principle is not altered, changed or modified.
