Abstract

The invention relates to an electric water heater, which comprises a liner assembly (2) and a heating pipe (1) arranged in the liner assembly, and is characterized in that one or more stirrers (3) are arranged in the liner assembly (2). The invention adopts the structure that the stirrer is arranged in the inner container assembly, when the electric water heater is heated, the stirrer stirs water in the inner container, so that the temperature of the water in the inner container is uniform, and cold water dead angles in the inner container are eliminated, therefore, the invention greatly improves the heat production water rate and meets the requirements of users.

Description

an electric water heater

technical field

The invention is an electric water heater, which belongs to the innovative technology of the existing electric water heater.

Background technique

The electric water heater liner in the prior art usually adopts a horizontal placement structure, and one or more heating tubes are installed in the liner, and the heating tubes are installed on the inner wall of the liner. When the heating is stopped at a fixed temperature, the water temperature in the area near the heating tube in the inner tank is high, and the water temperature in the area far from the heating tube is low, resulting in a large temperature difference in the water temperature in the inner tank, and the electric water heater has a low rate of hot water production, which is not good. to meet the needs of users.

Contents of the invention

The purpose of the present invention is to overcome the above disadvantages and provide an electric water heater that can make the water temperature in the inner tank uniform, greatly increase the heat production rate, and meet the needs of users.

The technical solution to realize the purpose of the present invention is: the present invention includes an inner container assembly and a heating tube placed in the inner container assembly, wherein one or more agitators are installed in the above-mentioned inner container assembly.

The above-mentioned agitator is connected with a motor placed outside the liner assembly.

A sealing member is provided between the rotating shaft of the motor and the inner container or between the rotating shaft of the agitator and the inner container.

A heating pipe is installed in the upper part of the above-mentioned liner assembly, and a stirrer is installed in the lower part.

The above-mentioned liner assembly is equipped with three agitators, the three agitators are respectively located in the upper, middle and lower positions of the liner, and the three agitators are respectively connected with three motors placed outside the liner assembly.

Because the present invention adopts the structure that the agitator is installed in the inner tank assembly, when the electric water heater is heated, the agitator stirs the water in the inner tank, so that the water temperature in the inner tank is uniform, and the cold water dead angle in the inner tank is eliminated. The hot water production rate is improved to meet the needs of users.

Description of drawings

Fig. 1 is a structural schematic diagram of the present invention.

Detailed ways

The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing

Example 1:

As shown in FIG. 1 , the present invention includes a liner assembly 2 and a heating tube 1 placed in the liner assembly, wherein one or more agitators 3 are installed in the liner assembly 2 . Above-mentioned stirrer 3 is connected with the motor 5 that is placed outside the liner assembly. In order to prevent the inner container from leaking, a sealing member 4 is provided between the rotating shaft of the above-mentioned motor 5 and the inner container or between the rotating shaft of the agitator 3 and the inner container.

In this embodiment, a heating tube 1 is installed in the upper part of the above-mentioned liner assembly 2, and a stirrer 3 is installed in the lower part. If the user uses less hot water, only the heating tube 1 can be started to work alone. If the user uses a large amount of hot water, start the heating pipe 1 and the agitator 3 to work at the same time, and the cold water at the bottom of the inner tank is mixed with the hot water at the top while heating, which can increase the amount of hot water produced and meet the needs of users.

Example 2:

The difference between this embodiment and Embodiment 1 is that three agitators 3 are installed in the inner container assembly 2, and the three agitators 3 are located at the upper, middle, and lower positions of the inner container respectively. Three motor connections on the outside of the assembly. Other structures are the same as in Embodiment 1.
