Description

PASSIVE OR STAND BY VOLTAGE ELIMINATOR DEVICE

TECHNICAL FIELD

The present invention relates to a device that detects and blocks the fluctuations that may occur in the residential electrical system and passive voltage eliminator, where the element corresponds to a compact electronic unit that has software that eliminates standby or consumption in standby mode in household appliances, while being environmentally friendly thanks to its solar-type internal power system and also, it allows protection thanks to its system of detection and automatic blocking of transient disturbances that can be generated in the residential electrical system. The electronic unit of the present invention thus has a microcontroller, a series of digital and analog ports, a USB connection port, a general purpose platform based on AVR and software that controls all the elements of the device to obtain the desired result. .

BACKGROUND OF THE INVENTION

Currently, transient fluctuations or disturbances in the electricity supply network, which generate a very short duration voltage increase, where these instabilities jeopardize the normal operation of the appliances that are connected to the electricity grid and It can affect them permanently.

The changes in voltages that present due to fluctuations or variations, almost imperceptible in the supply network, can produce short circuits either instantaneously or over time and cause damage to the device, thus shortening its life. Useful.

Thus, these changes or fluctuations in the electricity supply network usually occur or more commonly in remote municipalities or that are not located within the country, that is, in smaller cities or municipalities that have a system of power supply that is not very reliable, while not very stable and has regular cuts. On the other hand, currently most of the existing appliances in each of the homes, offices and others, have a plurality of electrical and / or electronic circuits that allow their proper functioning, where said circuits have a series of elements that show the status of the device, either turned off or on by means of light bulbs, indicators, etc., where these elements make a minimum consumption of electrical energy.

Thus, there are many users of residential electrical energy that do not have any discomfort in that the indicator light of standby or standby function, usually red, which have digital appliances, remain on for hours even though no one is using such appliances, without taking into account that this indicator makes a consumption called "passive consumption" or standby, which can represent between 5% and 15% of the value of electricity that is canceled monthly by the power supply, that is, its consumption is considered as "minimal" or "irrelevant" that the user does not know its true value.

Similarly, passive voltage or electronic standby also helps increase the emission of gases that produce the greenhouse effect, especially carbon dioxide (CO2), taking into account that they make a constant consumption of electricity. As reported in different publications this consumption emits the same amount of carbon dioxide that a car would do when traveling around the world 4000 times on a trip that would last 170 years at an average speed of 100 kilometers per hour (See, https://dialnet.unirioia.es/serylet/articulo?codigo=4465117)

Thus, in the state of the art there is a plurality of disclosures related to devices that are used for the elimination of passive voltage or the stabilization of the electricity supply network, within which JP JP 2010049998 is described, which describes an electrical outlet or plug and a power supply switch device that have a solar cell or module, where the device is used to reduce power consumption in passive or standby voltage mode. Thus, the device is provided with an output terminal to supply the energy supplied from an electrical power network to an electrical unit, a solar cell to generate energy from the received light, and a switch to switch the conduction or non-conduction between the mains and the output terminal, where the switch is arranged so that it is activated with the power of the solar module.

However, the device described in the foregoing presents a series of disadvantages since it does not mention a system or mechanism for controlling fluctuations in the electricity supply network, which does not prevent household appliances from being damaged due to said fluctuations or variations. of voltage, which is undesirable, while not having any type of control element to cut the energy to the circuit, which leads to possible errors by passive elements that do not work properly or can have control over them. On the other hand, there is document US 7765416, which defines a control device for a power supply with zero power consumption in the standby mode, which comprises an activator, an intermediate relay, a power relay, a circuit of signal induction, a power supply monitoring circuit, a power interruption circuit, a microcomputer or simple chip and a battery. Thus, the device is used to control the power supply in household appliances. Thus, when the signal induction circuit receives a standby command, the microcomputer causes the intermediate relay and the power relay to cut off the AC power supply to the equipment controlled by means of the activator, and at the same time, it is cut off. the power supply to the microcomputer and the intermediate relay through the interrupt circuit.

However, this priority has the disadvantage that its power supply takes it directly from the network, that is, it requires the same electricity network to cut the passive voltage consumption, which translates into a passive consumption by the device to eliminate the passive consumption of the appliance, which does not eliminate any type of consumption in general in the home where it is installed. Likewise, this device does not include a fluctuation control module in the power grid, so it cannot be used to regulate voltages or prevent possible damage to household appliances. However, in the state of the art there is also document CN 202930683 that discloses an intelligent power supply connector that is capable of eliminating power consumption in standby mode, thus solving the problem related to the consumption generated by the appliances when the connector does not turn off. Thus, the intelligent connector comprises a main body portion and an intelligent control portion, wherein the body includes a connector body; and the intelligent control portion consists of a current sensor, an amplification circuit, a comparator, an execution circuit, a relay and a timed off switch. Specifically, the signal input terminal of the current sensor is connected with a cable from the connector body. The smart connector is suitable for residential and office use or the like.

However, as with the document defined above, this priority has the disadvantage that it does not have an alternative mechanism or system for supplying electricity other than the supply network, which ultimately does not completely eliminate the passive consumption, as previously explained. Likewise, said device of the foregoing presents the problem that does not mention the control of fluctuations in the power grid and does not prevent damage to the appliances connected to the power grid.

Finally, there is document CN 203722005 that teaches a smart energy-saving connector or plug with lightning protection which includes a cover, a first connection piece and a second connection piece. A control module disposed within the cover comprises a programmable control device as well as a power circuit, a sampling circuit and a time delay control circuit which are electrically connected to the device separately. The programmable control device is used to input a signal to the time delay control circuit. The device reduces the standby energy consumption of an energy saving appliance, and has properties such as auto-off, lightning protection, electric shock prevention and the like.

However, the device described in this above has the disadvantage that it does not use an alternate source to take the energy for its own operation, but instead uses the same power from the electricity grid, thus generating voltage consumption. by its components, which is undesirable and does not meet the proposed objective.

Taking into account this information defined in the preceding paragraphs, the state of the art discloses a series of standby mode eliminating devices that allow eliminating passive or standby voltage consumption in household appliances, where in most cases the electrical energy to power The device comes directly from the electricity grid and in a single case, this energy is taken by means of a solar cell or module. Likewise, there is a document that mentions some protection against sudden changes or spikes in the supply of electricity from the supply network.

However, in the state of the art there is no disclosure that teaches a single simple device that allows the elimination of standby mode in appliances, that is of the plug or connector type, and that also has some protection mode against fluctuations in the supply of energy directly from the network and thus can ensure the operation of the appliance, where all this is done through a microcontroller and a series of electronic elements that obtain their energy through a cell or a solar module, without using the power grid In accordance with the above, it is clear and evident that in the state of the art there is a need to design and implement a compact electronic device that allows the elimination of passive or standby voltage that occurs in appliances in homes or offices, where the device has an electronic control system that allows permanent control over it, where the device is also required to regulate fluctuations or variations in the electricity supply network protecting in the same way to the appliance. Additionally, it is necessary that the device has some type of alternative energy supply system, either solar or similar, in order not to make use of the energy coming from the power grid and thus completely eliminate the voltage consumption passive or standby, which allows and helps reduce energy costs in a home or office.

SUMMARY OF THE INVENTION

The present invention is directed to a compact electronic device that allows the elimination or suppression of passive consumption voltage in household appliances, at the same time as it has a regulation system for the received voltage signal, which helps with the elimination of fluctuations or variations in the voltage that comes from the power supply network. In addition, the device of the present invention is environmentally friendly thanks to its solar internal power system and protects thanks to its automatic detection and blocking system to the appliances commanded by this

unit of transient disturbances that are generated in residential electrical system.

Thus, the device of the present invention corresponds to a mechanism for detecting and blocking fluctuations in the residential electrical system and eliminating passive voltage, where the element corresponds to a compact electronic unit that has software that eliminates standby or consumption. in standby mode in household appliances, while being environmentally friendly thanks to its solar-type internal power system and also, it allows protection thanks to its system of detection and automatic blocking of transient disturbances that can be generated in the residential electrical system.

The electronic device of the present invention then has a microcontroller that allows control over all the elements in order to achieve a voltage regulation and a passive or standby voltage elimination properly, one digital and analog ports for input and data output, a USB connection port, a general purpose platform based on AVR and software that controls all the elements through the microcontroller, where the software and the microcontroller also allow data from the device to be extracted to make a due follow up and
