High-efficiency, energy-conserving and electromagnetical instantaneously heated type safety water heater and method for manufacturing same

Abstract

The present invention discloses a high-efficient energy-saving instant-heating safety heater and a production method thereof, wherein, the heater adopts an electromagnetic oven to heat, and is characterized in that the surface of an electromagnetic oven tray is provided with a sealed box body that is made of iron material or stainless steel material and is provided with two layers or more that are separated from each other; each layer of the sealed box body is provided with water and provided with the disc-shaped heat-conducting pipe that is made of the copper pipe, and the heat conducting pipes inside each layer of the sealed box body are communicated with each other; at the same time, the electromagnetic coil supporting plate that is arranged inside the electromagnetic oven adopts the ceramic material to be made into an electromagnetic coil supporting plate with a water cycling passage; the outlet of the water cycling passage of the supporting plate is connected with a water inlet of the heat conducting pipe that is arranged inside the most upper layer of the sealed box body, so that the water that flows inside the heat conducting pipe can be rapidly heated. The electromagnetic oven is used to heat, so that the electricity not only can be completely separated from the water, so as to improve the security of the user, but also can improve the energy source utilization rate.

Description

Technical field: [0001] The invention relates to a water heater and a manufacturing method of the water heater, in particular to a high-efficiency energy-saving electromagnetic instantaneous safety water heater and a manufacturing method thereof. technical background: [0002] At present, water heaters have long become a kind of conventional household appliances. Among them, electric heating is mainly divided into two types, one is the volumetric type with an earlier service life, and the other is the instant heating type newly launched in the past two years, whether it is The volumetric or instant heating basically uses an electric heating rod to heat directly in the water to produce hot water. Therefore, it is impossible to truly separate the water and electricity in the structure, so the absolute safety of the user cannot be guaranteed in use.

Problems solved by technology

[0002] At present, water heaters have already become a kind of conventional household appliances. Among them, electric heating is mainly divided into two types, one is the volumetric type with an earlier service life, and the other is the instant heating type newly launched in the past two years. The volumetric type or the instant heating type basically use the electric heating rod to directly heat the water to make hot water. Therefore, it is impossible to truly separate the water and electricity in the structure, so the absolute safety of the user cannot be guaranteed during use. Some good In order to prevent electric leakage, the brand installs firewalls on the electric water heaters. Although this improves the safety of users, it also greatly increases the production cost of electric water heaters.

At present, the instant water heaters on the market, whether imported or domestic, basically use multiple electric heating rods with a single power of 1.5KW to 2KW to be installed on a heating rod with a diameter of 40mm to 50mm and a length of 100mm to 150mm. In the metal heating drum, the cold water flowing through the heating drum is heated by concentrated heating; due to the limited distance flowing through, the length is not enough, and the heating time is too short, so although the power used is relatively large, it generally reaches 6KW ~8KW or more, but there are still two main defects. First, because the power of household electric meters used by urban residents in my country is generally single-phase 20A, it cannot meet the load of superheaters and other household appliances at the same time; second, when the water flow is too large At the same time, the temperature or pressure of the outlet water often does not meet the user's requirements, so the practicability is not high, and it is basically at the point where few people care about it in the market.
