TH14837B - Electric water heater - Google Patents

Abstract

Electric water heater Including control unit and heating unit with container Contain water and the electric heating coil inside the water container. Here, the perforated heat conduction cylinder is stranded in the surrounding water container. Electric heating coil To separate the empty space inside the water container into the inner heating and outer preheating rooms. Perforated heat conduction strips are encircled around the cylinder section. To separate the preheating to the first heating chamber at the bottom and the second preheating chamber at the top. Solenoid-changeable resistance The state of this control unit has a heat sink attached to the water collector chamber of the cold water pipe. Which brings cold water to the room to heat it first Which the heat sink transmits heat from the heat Solic-state interchangeable resistance to cold water in this water collection chamber.

Claims (9)

The thermal conductive casing bar has a small number of holes. For allowing water to pass through The aforementioned first stage to the aforementioned second stage And later into the heating chamber through a small hole in the heating cylinder. Pressure-activated switch devices Water is installed in such an inlet pipe for cold water to turn on the control unit automatically. When the cold water is Leads to the pipes for cold water entering the said insulated water container Or turn off the control unit This automatically applies when the cold water is stopped from passing through the cold water inlet. 2. Electric water heater with pre-heating chamber. And the second step according to claim 1. Here, the aforementioned cold water inlet pipe consists of a water storage chamber for collecting cold water. Such a solid-state convertible resistance There is a cooling panel at the back very close. A lot is attached to the water collection chamber of such inlet chilled water pipes for heat transfer from the heat. Such a solid-state convertible resistance to the cold water in the storage chamber. 3.Electric water heaters with the first and second preheating chambers in accordance with claim 1. Here, the connection area is between the radiators of the replaced resistance. Such a solid-state value. And the water collection chamber of the chilled water inlet pipe is also sealed. Water seal ring 4. Electric water heaters with the first and second preheating chambers in accordance with claim 1 also include a pressure relief valve installed in the pipes for cold water inlet. To release excess pressure from the said heating unit 5. Electric water heaters with the first and second preheating chamber according to claim 1, here the temperature control switches are stepless fine-tuning switches. 6. The electric water heater with the first and second preheating chamber according to claim 1 also consists of a temperature display device installed in the pipe for hot water to point out. Automatically shows the temperature of hot water passing through the hot water pipe. 7.Electric water heaters with the first and second preheating chambers in accordance with claim 1. Here, the appropriate conduction cylinders are made of red bronze. 8. Electric water heaters with first and second preheating chambers in accordance with claim 1. Here, there is at least one such insulated water container with at least one ear hook for hanging. 9.Electric water heaters with first and second preheating chambers according to claim 1. Here, the water pressure-activated switch consists of a small switch and a chamber for Water pressure balance The chamber for such water pressure balance separates the collection chamber. From the pushrod diaphragm, the pushrod diaphragm has a sealing ring. Was built at the periphery that was anchored between two adjacent chambers where a room for balance The water pressure consists of a "T" push rod that is encased in the chamber for balance. Of such water pressure And has a hole in the axial direction of the aforementioned "T" push rod. It is enclosed in the chamber for the balance of the water pressure to exert pressure on the "T" push rod against the pushrod diaphragm. The small switch is encased on the top of the control unit by a fixed plate. It consists of a lever for controlling a protrusion from a small switch. And a magnet that is encased on the tip Of the control lever is connected with the magnet of the "T" push rod.
