This creative department belongs to the technical field of electric water heaters, especially an electric water heater with energy-saving and instant heat function, which can improve the hot water discharge efficiency, achieve the purpose of small volume and high efficiency, and effectively improve its practicability and safety. Sex.

According to the type of existing electric water heaters, there are two types of heat storage type and instant heat type. Among them, the heat storage type electric water heater is characterized in that it can provide a stable amount of hot water, but at least there are the following defects or limitations; First, because it requires a large water storage tank, it is bulky and takes up space. Second, there are many buried pipelines and the installation process is troublesome. Third, waiting for reheating to the available temperature for a long time (about 1 hour), can not continue to provide hot water use. Fourth, because of the large amount of water stored, the power consumption during heat preservation is large.

As for the instant heat electric water heater, it has the characteristics of small size and short installation pipeline, but it has the following defects or limitations; first, because the water temperature will change with the amount of water, the phenomenon that the water temperature suddenly becomes hot and cold . Second, the water pressure switch cannot be used when the water pressure is insufficient, so it is difficult to apply to the residents of the building or the end of the pipeline. Third, it is impossible to provide hot water immediately, wasting water and water.

In order to solve the problems faced by the aforementioned heat storage type or instant heat type electric water heater, an electric water heater having both heat storage type and instant heat type function has been developed, such as As shown in the first and second figures, an upper partition (11) is disposed adjacent to the top end of the inner cylinder (10), so that the inside of the cylinder (10) is divided into a high temperature tank (101) and a low temperature tank (102). Further, the upper partition plate (11) is provided with a downwardly extending sleeve (12) at the center of the bottom surface, and a heating groove (103) is formed inside the sleeve (12), and the bottom end of the sleeve (12) and the cylinder A through hole (120) is formed between the bottom of the body (10) for allowing the water source to flow, and the upper partition (11) is formed with a constant hole (110) in the range of the sleeve (12) to make the cylinder (10) The high temperature tank (101) and the low temperature tank (102) are mutually permeable, and the bottom end of the cylinder (10) is provided with a sleeve (20), and the sleeve (20) is provided with a plurality of extension sleeves ( 12) The inner heating rod (21), and the bottom of the cylinder (10) is provided with a cold water pipe (32) connected to the inlet pipe (30), and the water outlet of the cold water pipe (32) corresponds to the cylinder (10) low temperature tank (102), at the bottom of the cylinder (10), a hot water pipe (33) connected to the water outlet pipe (34) is provided, and the hot water pipe (33) is passed through the upper partition plate (11) through the sleeve (12) (110). ), so that the water inlet corresponds to the low temperature tank (102) of the cylinder (10), and the other sleeve (20) is provided with a pressure relief valve (35) to prevent the cylinder (10) from being overpressured. Thus, after the cold water enters the low temperature tank (102) of the cylinder (10) through the cold water pipe (32), it can be injected into the heating tank (103) of the casing (12), and the heating tank (103) is used in the casing (12).

The tank (102) flows into the casing (12) to be heated and the temperature rises into the high temperature tank (101). Since the heating tank (103) and the high temperature tank (101) are groove-shaped, the heating can be improved without mixing. Efficiency and save energy.

However, since the heating rod (21) needs to penetrate the casing (12) and approach the upper partition (11), the length of the heating rod (21) is long, so that not only material is wasted, but also cost is increased; and because of the heating rod (21) ) It is suspended, so it is easy to generate vibration due to energy fluctuation during heating, and noise is generated. At the same time, the space of the low temperature tank (102) is large, which causes the amount of cold water to increase. The invisible temperature will reduce the heating efficiency, and the water temperature will decrease, resulting in the hot water output. Insufficient, and there is a phenomenon of wasting electric energy; in addition, since both the hot water pipe (33) and the heating rod (21) are located in the casing (12), the two are too close, so that the hot water pipe (33) is easily heated to generate calcium carbonate. Causing the phenomenon of jamming, affecting the amount of hot water, and forming maintenance problems.
