Definitions

  • the invention is in the field of mechanical engineering, especially cooling and heating equipment.
  • the present invention relates to a water heating system suitable for providing heated water for short time activity.
  • the invention generally comprises these main parts: a DC power supplier that installed outside of using space, a water tank which is always full of water, an electrical heater system which heats the water inside the tank by a safe direct current, a heat exchanger performs heat exchange between the heated water inside the tank and the consumed water flows through the heat exchanger and some thermostats which supply hot water at desired temperature for summer and winter uses.
  • inlet pipes(10) and output pipe(20), respectively are the water input line to the instant water heater unit and the outlet hot water line comes out from the instant water heater unit.
  • Item(30) is a schematic of a whole tank assembly, which its components will be described hereinafter.
  • Item 40 is a direct current power supply.
  • the power supply(40) is located out of the bathroom space which makes safe the operation of the unit.
  • the hot water output(20) of the system is connected to the split water tap and allows for use in both low valve and shower mode.
  • the main inlet water pipe(10) which preferably is hot water line, enters directly into the whole tank assembly (30) and connects to the heat exchanger(34).
  • the other main pipe(50) or cold flow line(50) goes directly to the tap so that the user can adjust the water temperature if necessary.
  • the water tank(33) inside the tank assembly(30)always contains water which is filled through valve(31a) and discharged by valve(32b).
  • An water level indicator(35) shows the amount of water in the tank.
  • the water inside the tank(33) is heated by at least an electrical heater elements(39) and the water temperature is controlled by the thermostats(37) or similar heat controller device located in the water tank (33).
  • the heat exchanger(34) used in the water tank(33) is connected to the water inlet line(10) which causes the heat transfer between the heated water stored in the water tank(33) and the outlet water from pipe(20).This way, when the tap is opened, the consumer will not wait for the water to warm up.
  • the electrical components such as emergency power button(32), power cable divider(36), thermal thermostat(37), indicator lamps(38) and electrical heater elements(39) are connected to a 12V DC power cable. These components function systematically as long as the power supply is maintained and as soon as the power supply is disconnected by the emergency button(32), the heating process stops.
  • the electric system can supply hot water consumed at about 60 °C (summer mode) and 70 °C (winter mode). It is important to note that the thermostat (37) is regulated at 80°C for system disconnection threshold and if the water temperature rises above 80°C, the heating operation stops.
  • Components 40 ,41, 42 belongs to power switching or power supply(40).
  • Power Supply (40) is a rectifier that converts the alternating current to 12 V direct current .
  • the switch(41) has three modes which includes summer, winter and OFF modes.
  • the unit When the unit is not in use for a long time by the switch in the OFF state, the unit operates in a non-functional style in the whole water cycle.
  • the water temperature in the tank(33) In winter or cold weather, the water temperature in the tank(33) is set between 50°C to 65 °C, and in summer or hot weather, the water temperature is set between 35°C to 45°C.
  • a calibrated thermostat can be used which works between 30°C and 70°C instead of the tripod switch.
  • thermal thermostats As shown in the electrical line for the 60°C and 70°C thermostats, known as thermal thermostats, comes from the negative terminal of the two separate power supplies. These two line have two switch that are distinguished by the three-state switch(41). When using the unit, summer and winter modes are indicated by LED lamps(38). The thermostat outlet is attached to the body of the tank to prevent danger. The heater elements (39) are fed from the positive terminal of the power supply.
  • the power supply of this unit is installed outside the bathroom space and supplies a 12V DC current to the tank unit installed in the bathroom. As a result of the use of 12V direct current and low amperage current there is no danger to the users.
  • the whole unit is in constant operation and the water is constantly heated to a temperature between 40°C and 60°C.
  • the optimal operation temperature in the tank and heat exchanger is 50°C.
  • heat exchanger highly heat-conductive metals and alloys such as copper, may be used.
  • the type and dimensions of the heat exchanger is not limited to this example.
  • Discharge valve(31b) at the bottom of the tank is used for drainage or displacement of the water tank(33).
  • Inlet pipe(10) and outlet pipes(20) are selected from the types of common pipes used in building plumbing such as galvanized pipes or multilayer pipes.
  • the size of the pipes varies depending on the type of use or tank, but in home samples the diameter of the pipe is between one and three centimeters and preferably is two centimeters. These pipes are connected to each other and to the tank with a variety of common fittings device in the industry.
  • the main components of the instant water heater unit are:
