Description

Technical Field

[0001] The utility model belongs to the technical field of water heating devices, and particularly relates to a water outlet structure for instant electric water heaters. Background Art

[0002] Instant electric water heaters can heat the outlet water quickly. Due to the convenience of taking hot water, their use has become more and more common. An inner tank is usually arranged in the electric water heater, and the inner tank includes an upper cover, a shell, and a lower seat. A heating water chamber is arranged in the shell, a heating pipe is arranged in the heating water chamber, and a water inlet main is arranged in the lower seat. A regulating valve core is arranged on one side of the inner tank. After adjusting the amount of water, the water enters the heating water chamber, is heated by the heating pipe, and finally flows out from the water outlet pipe at the upper cover. The water flow in the heating water chamber will flow from bottom to top, but the water flow is non-directional in the heating water chamber, which will make different water flows flow through different lengths, which will eventually lead to unstable water temperature of the water outlet pipe, and at the same time cause uneven heat distribution of the heating pipe, affecting the life of the heating pipe. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a water outlet structure for instant electric water heaters with reliable connection of wiring pipes and good sealing performance.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a water outlet structure for an instant electric water heater, the instant electric water heater includes an inner tank, and the inner tank includes an upper cover, a shell body, and a lower seat in order from top to bottom, a heating water cavity is arranged in the shell body, the lower seat is provided with a water inlet main pipe, a heating pipe is arranged in the heating water cavity, the bottom surface of the shell body is provided with a mounting column for inserting the electrode end of the heating pipe, and a water inlet pipe for connecting to the water inlet main pipe, a water outlet is arranged on the side wall of the shell body, the water inlet pipe is arranged on one side of the water outlet, and a block is arranged on the other side of the water outlet, the side surface of the mounting column is an arc surface and is arranged corresponding to the water outlet, and the height of the block is greater than the height of the water inlet pipe.

[0005] Compared with the prior art, the utility model has the advantages that water flows into the valve core from the water inlet pipe, and then the water volume is adjusted by the valve core before rushing into the heating water chamber through the water outlet. Due to the blocking of the mounting column corresponding to the water outlet, and the height of the block on one side of the water outlet is greater than the height of the water inlet pipe on the other side, the water flow is guided by the arc surface of the mounting column, impacts the side above the water inlet pipe, and then forms a spiral flow after encountering the side wall of the shell, and then flows out of the water outlet pipe after being heated by the heating tube in the spiral direction from bottom to top. The length of water flowing through the heating tube is relatively consistent, the heating is uniform, and the flow water resistance of the water flow in the heating water chamber is smaller, the heat distribution in the heating water chamber is uniform, and the overall life of the instant electric water heater is longer.

[0006] Furthermore, the height of the side wall of the mounting column is greater than the height of the water inlet pipe.

[0007] Furthermore, a first baffle is arranged between the installation column and the baffle, and a second baffle is arranged between the water inlet pipe and the installation column.

[0008] Furthermore, the side wall protrusion of the shell is provided with a blocking strip extending in the axial direction.

[0009] Furthermore, the axis of the mounting column is staggered with the axis of the shell, the mounting column includes a first side wall close to the side wall of the shell, and a second side wall away from the side wall of the shell, the block is arranged on the side of the water outlet close to the first side wall, and the baffle is arranged on the side of the shell close to the first side wall.

[0015] like Figures 1 to 4 As shown,

[0016] A water outlet structure for an instant electric water heater, the instant electric water heater comprises an inner tank, the inner tank comprises an upper cover 1, a shell 2, and a lower seat 3 in order from top to bottom, a heating water chamber 2.1 is arranged in the shell 2, the lower seat 3 is provided with a water inlet main pipe 3.1, a heating pipe 2.2 is arranged in the heating water chamber 2.1, a mounting column 2.3 for inserting the electrode end of the heating pipe 2.2 and a water inlet pipe 2.4 for connecting to the water inlet main pipe 3.1 are arranged on the bottom surface of the shell 2, a water outlet 2.5 is arranged on the side wall of the shell 2, the water inlet pipe 2.4 is arranged on one side of the water outlet 2.5, a stopper 2.6 is arranged on the other side of the water outlet 2.5, the side surface of the mounting column 2.3 is a circular arc surface and is arranged corresponding to the water outlet 2.5, and the height of the stopper 2.6 is greater than the height of the water inlet pipe 2.4.

[0017] A valve core is provided on one side of the shell 2. The water inlet pipe 2.4 is a hollow structure. One end of the water inlet pipe 2.4 is connected to the water inlet main pipe 3.1, and the other end is connected to the valve core inlet 4.1. The valve core adjusts the water volume by rotating the opening. The valve core outlet 4.2 is connected to the water outlet 2.5.

[0018] like Figure 4 In the embodiment, the mounting column 2.3, the water inlet pipe 2.4 and the stopper 2.6 are surrounded at the water outlet 2.5, and a cavity is formed under the blocking of the first baffle 2.7 and the second baffle 2.8, and the heights of the stopper 2.6, the mounting column 2.3 and the water inlet pipe 2.4 are sequentially lowered, so that the water flows in the direction a from the stopper 2.6 toward the water inlet pipe 2.4 after rushing out of the water outlet 2.5, and flows along the direction b toward the side wall of the shell 2 under the guidance of the arc surface of the side of the mounting column 2.3, and flows along the direction c under the blocking of the side wall of the shell 2, forming a spiral water flow, and finally circulates in the direction d to form a continuous spiral rise, thereby ensuring the uniformity of the water flow and the consistency of the water temperature, reducing the water resistance and increasing the life of the electric water heater.

[0019] Since the heating tube 2.2 has two motors, there are also two mounting columns 2.3. The present application selects the mounting column 2.3 close to the water outlet 2.5.

[0020] Among them, the side wall protrusion of the shell 2 is provided with a baffle 2.9 extending in the axial direction, and a heating tube 2.2 is arranged in the shell 2. The distance between the side wall of the heating tube 2.2 and the side wall of the shell 2 is consistent in the circumferential direction. By setting the baffle 2.9, the distance between the side wall of the heating tube 2.2 and the side wall of the shell 2 at d can be reduced, the cross-sectional area of ​​the water flow spiral passing through can be reduced, the water flow velocity at d can be increased, and the power of the water flow spiraling from bottom to top can be improved.

[0021] Among them, the axis of the mounting column 2.3 is staggered with the axis of the shell 2, and the mounting column 2.3 includes a first side wall 2.10 close to the side wall of the shell 2 and a second side wall 2.11 away from the side wall of the shell 2. The block 2.6 is arranged on the side of the water outlet 2.5 close to the first side wall 2.10, and the baffle 2.9 is arranged on the side of the shell 2 close to the first side wall 2.10. Since the block 2.6 is the highest and the block 2.6 is arranged on the side of the water outlet 2.5 close to the first side wall 2.10, the block 2.6 blocks the water outlet 2.5 and pushes the water flow toward the second side wall 2.11. After the water flow is blocked by the side wall of the shell 2, it advances in a spiral shape along the side wall of the shell 2 until it rotates to the side of the first side wall 2.10. After encountering the baffle 2.9, the cross-sectional area of ​​the flow is reduced and the flow rate is increased, and then the next spiral advance is performed.

[0022] The above description is only for the best embodiment of the utility model, but it cannot be understood as a limitation of the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
