Description

AQUECEDOR DE ÁGUA ELÉTRICO DE CONSUMO REDUZIDOREDUCED CONSUMPTION ELECTRIC WATER HEATER Campo da invençãofield of invention

[001] Refere-se a presente patente a um equipamento de aquecimento de água, inserido no campo técnico de aquecedores elétricos de passagem para água, o qual possibilita um menor consumo de energia elétrica.[001] This patent refers to a water heating equipment, inserted in the technical field of electric water heaters, which allows a lower consumption of electricity.

Fundamentos da invençãoFundamentals of the invention

[002] Atualmente o aquecimento elétrico de água é obtido através de um chuveiro, aquecedor de passagem instalado na tubulação ou aquecedor tipo reservatório. No caso do chuveiro e do aquecedor de passagem, a água é aquecida ao passar por uma resistência elétrica e no caso do reservatório a água contida no mesmo é aquecida devido ao contato com uma resistência elétrica.[002] Currently, electric water heating is obtained through a shower, passage heater installed in the pipe or reservoir-type heater. In the case of the shower and the passage heater, the water is heated by passing through an electrical resistance and in the case of the reservoir, the water contained in it is heated due to contact with an electrical resistance.

[003] O aquecimento da água fornecido pelo chuveiro e pelo aquecedor de passagem, ocorre de forma instantânea, sendo necessária a utilização de resistência elétrica de elevada potência, o que resulta em alto consumo de energia elétrica. Já no caso do reservatório, devido ao grande volume de água, também necessita de resistência elétrica de elevada potência, resultando também em alto consumo de energia elétrica.[003] The heating of the water provided by the shower and the passage heater occurs instantly, requiring the use of high-power electrical resistance, which results in high consumption of electricity. In the case of the reservoir, due to the large volume of water, it also needs high power electrical resistance, also resulting in high consumption of electrical energy.

[004] A presente invenção reduz consideravelmente o consumo de energia elétrica, sendo que a mesma consiste em um recipiente hermeticamente fechado, com isolamento térmico interno, o qual possui em seu interior uma serpentina de cobre, por onde passa a água e uma resistência elétrica no centro desta. Desta forma, o aquecimento da água se dá por irradiação e convecção, não havendo contato direto com a resistência elétrica. Devido ao recipiente estar fechado e isolado termicamente, cria-se um efeito “forno” o qual se obtém maior eficiência no aquecimento, resultando em menor consumo de energia elétrica. Enquanto os equipamentos citados utilizam resistências de aproximadamente 5000 watts, a referida invenção utiliza resistência de aproximadamente 800 watts, cerca de 80% de economia de energia.[004] The present invention considerably reduces the consumption of electrical energy, and it consists of a hermetically closed container, with internal thermal insulation, which has a copper coil inside, through which the water passes and an electrical resistance in the center of this. In this way, the heating of the water takes place by irradiation and convection, with no direct contact with the electrical resistance. Due to the container being closed and thermally insulated, an “oven” effect is created which achieves greater efficiency in heating, resulting in lower consumption of electricity. While the aforementioned equipment uses resistance of approximately 5000 watts, the aforementioned invention uses resistance of approximately 800 watts, approximately 80% energy savings.

[005] Além da eficiência em economia de energia elétrica, o que torna a invenção um produto “verde”, ou seja, ecologicamente correto, a mesma tem baixo custo de produção, ocupa pouco espaço, pode ser instalado direto no ponto de consumo, evitando tubulação exclusiva para água quente, ou mesmo instalada como sistema de aquecimento central.[005] In addition to the efficiency in saving electricity, which makes the invention a “green” product, that is, ecologically correct, it has a low production cost, takes up little space, can be installed directly at the point of consumption, avoiding piping exclusively for hot water, or even installed as a central heating system.

[008] A água passa pela válvula (9), acionando a resistência elétrica dupla (5), que aquece o interior do recipiente (1), sendo este dotado de camada de isolamento térmico (2), e camada de material espelhado (3), de forma a alcançar elevada temperatura em seu interior, a qual é transmitida por convecção e irradiação à serpentina de cobre (4). Então a água, após passar pela válvula (9), passa pela serpentina de cobre (4), sendo aquecida o suficiente para um bom banho, com economia de energia elétrica de aproximadamente 80% em relação aos aquecedores e chuveiros elétricos existentes no mercado.[008] The water passes through the valve (9), activating the double electrical resistance (5), which heats the inside of the container (1), which is equipped with a thermal insulation layer (2), and a layer of mirrored material (3 ), in order to reach a high temperature inside, which is transmitted by convection and irradiation to the copper coil (4). Then the water, after passing through the valve (9), passes through the copper coil (4), being heated enough for a good bath, with electricity savings of approximately 80% in relation to heaters and electric showers on the market.

Exemplos de concretizações da invençãoExamples of embodiments of the invention

[009] A presente invenção pode ser utilizada como aquecedor central ou instalada diretamente no ponto de consumo, sendo esta possibilidade, mais econômica e também mais prática, devido à não haver necessidade de tubulação exclusiva para água quente.[009] The present invention can be used as a central heater or installed directly at the point of consumption, this possibility being more economical and also more practical, since there is no need for exclusive piping for hot water.
