Problems solved by technology
Generally, two heating rods are required on an electric water heater, and two independent casings are required for selection. The heating rods will also be pressed into a semicircle, and folded into a nearly circular shape so that they cannot be in close contact with the casing after being inserted into the casing to form a gap. Lead to the reduction of the heating effect and heating speed of the heating rod

The invention discloses a closed casing pipe built-in coupler serial heating device for a water storage type electric water heater. The device comprises a closed casing pipe, a coupling connector, a first electric heating bar and a second electric heating bar; the coupling connector is located in the closed casing pipe, the first electric heating bar is connected with one end of the coupling connector, the second electric heating bar is connected to the other end of the coupling connector; the electric contact ends of the first electric heating bar and the second electric heating bar extend out of the closed sleeve pipe. According to the closed casing pipe built-in coupler serial heating device, the inner diameter of the same casing pipe is tightly matched with the heating rod, the positive electrode and the negative electrode are separated, the coupler is placed in the same pipe, the coupler is connected with the two electric heating rods in series, so that the structure is simple, the safety and reliability are achieved, the manufacturing cost is low, the installation is very convenient and fast, the heat energy conversion efficiency is effectively improved, the production efficiency is effectively improved, and has the characteristics that the device is convenient to maintain and no need of water discharge during the replacement of the heating rod; therefore, the device is aproduct which has excellent performances in economical efficiency, technical performance and practicability.
Description
Technical field [0001] The invention relates to a series heating device with a closed sleeve built-in coupler for a water storage type electric water heater. Background technique [0002] Currently, there are two types of heating devices for storage-type electric water heaters on the market: direct contact with water and non-direct contact with water. The non-contact method is to install a water-isolating sleeve on the heating rod so that the heating rod itself does not contact water. Generally, two heating rods are required on electric water heaters, and two separate sleeves are required for selection. The heating rods will also be pressed into a semicircle, and after folding, they will become nearly circular so that they cannot be in close contact with the sleeve after being inserted into the sleeve to form a gap. The heating effect and heating speed of the heating rod are reduced. [0003] In order to overcome the above-mentioned shortcomings, we have developed a series heating...
