Abstract
The utility model provides an automatic controller for an electric water heater, comprising an electric heating element, a temperature controller and a rectifying diode device, wherein, the connecting circuit of the electric heating element and a power supply is connected with the temperature controller in series, and the temperature controller is composed of a rectifying diode connected with a pair of normally closed contacts of a double-pole sheet temperature controller in parallel. The utility model uses a simple control device to achieve the purpose that when water is heated to a definite temperature, heating power is automatically reduced so that heating noise is lowered.
Description
The utility model relates to a kind of automaton of electric heater power, is specially adapted to electric heater power simple automaton.
The electric water heater of prior art is constant in whole heating process, because water temperature constantly raises, the heat-transfer behavior of electrical heating elements also changing, produces obvious noise in this back process that just causes heating.In order to reduce noise, can reduce the power of heating element heater, can prolong heat time heating time but do like this, reduction adds heat aging.
The purpose of this utility model is the simple and easy control device that will provide in a kind of electric heater heating process, and heating power reduces automatically when water is heated to the higher temperature of a certain setting, improves with this fork-like farm tool used in ancient China to add thermal noise.
The purpose of this utility model is to realize by following scheme fork-like farm tool used in ancient China: power controller of series connection in the circuit of heating element heater, power controller is formed in parallel by a pair of normally closed interlock of a commutation diode and a temperature controller.When cold water heats, the closing of contact of a pair of normally closed interlock of temperature controller, heating total power place in circuit, this moment, the electric heater firing rate was very fast.When water temperature rising noise increases, relevant temperature and the normally-closed contact of the temperature controller that moves disconnects, the commutation diode in parallel with the temperature controller normally-closed contact inserts heater circuit, this moment heating pass through electric current for beginning the time half, heating power is 1/4 of a former fork-like farm tool used in ancient China, adds thermal noise and reduces greatly.Because water temperature, had so just been taken into account the reduction noise and has been added heat aging so the time lengthening of whole heating process is less near final heating-up temperature when diode inserted, and had improved the complete machine performance of electric heater product.
The utility model reaches when water is heated to uniform temperature by a simple and easy control device, and heating power reduces automatically, has realized reducing the purpose that adds thermal noise.
Description of drawings of the present utility model is as follows:
Fig. 1 is an electrical schematic diagram of the present utility model.
Be further described below in conjunction with accompanying drawing, as shown in Figure 1, the power controller of in the end that heating 1 and power supply join, connecting, power controller is formed in parallel by a pair of normally closed interlock 2 of a commutation diode 3 and a temperature controller.Temperature controller adopts bimetal strip thermostat simple in structure, and the temperature-sensitive surface of temperature controller is adjacent on the outer surface of heating container.When operation principle was cold water heating beginning, bimetal strip thermostat was failure to actuate, normally-closed contact 2 closures, and heating total power place in circuit, this moment, heating 1 firing rate was very fast.When water temperature rising noise increases, relevant temperature and the bimetal strip thermostat that moves, its normally-closed contact 2 disconnects, the commutation diode 3 in parallel with the temperature controller normally-closed contact inserts heater circuit, the electric current that passes through of heating 1 is half of when beginning, heating power is 1/4 of a former fork-like farm tool used in ancient China, adds thermal noise and reduces greatly.Because water temperature was near final heating-up temperature when diode 3 inserted, the bimetal strip thermostat that can select specification between the 70--95c as required for use and move, so the time lengthening of whole heating process is less, so just take into account the reduction noise and added heat aging, improved the service behaviour of electric heater.The utility model is except reducing noise, because the power that water is heated to before the finishing temperature only is 1/4 of heating rated power, and the dry combustion method damage in the time of can improving the surface scale of heater element and lack of water for the electric heater of interior hot-water type.
