Embodiment 1

[0033] This embodiment proposes a structure for collecting hot water, such as Figure 1-Figure 4 As shown, it includes a cylindrical body 11 for covering the outside of the electric heating tube. The bottom of the cylindrical body 11 is opened to form a bottom opening 12. The upper end of the cylindrical body 11 has a top opening 13. The bottom opening 12 is used to accommodate The cold water located below the cylindrical body 11 enters the cylindrical body 11 and is heated by the electric heating tube located in the cylindrical body 11. On the other hand, the water inlet end of the outlet pipe can be inserted into the cylindrical body from the bottom opening. The cylindrical body 11 gathers the hot water heated by the electric heating tube and cannot flow freely, which reduces the heat exchange between the hot water around the electric heating tube and the nearby cold water, so that the high-temperature hot water gathers near the water inlet of the outlet pipe to improve The ...

Embodiment 2

[0051] This embodiment proposes another structural form of water-gathering structure, such as Figure 10 As shown, it includes a cylindrical body 21 for covering the outside of the electric heating tube. The bottom of the cylindrical body 21 is opened to form a bottom opening 22. The upper end of the cylindrical body 21 has a top opening, and the top opening is used to accommodate the tube The cold water below the cylindrical body 21 enters the sub-cylindrical body 21 and is heated by the electric heating tube located in the cylindrical body 21. On the other hand, the water inlet end of the outlet pipe can be inserted into the cylindrical body from the bottom opening, and the tube Shaped body 21 prevents the hot water heated by the electric heating tube from flowing freely, which reduces the heat exchange between the hot water around the electric heating tube and the nearby cold water, so that high-temperature hot water gathers near the water inlet of the outlet pipe to improve...

Embodiment 3

[0055] The present invention proposes an electric water heater, such as Figure 13 As shown, it includes an inner tank 31, an outlet pipe 32, and a heating tube 33. The heating tube 33 is fixed to the inner tank through a flange 34, and also includes the hot water gathering structure described in Embodiment 1. For details, see Figure 1-Figure 9 As shown, the heating pipe 33 includes at least a top heating pipe 331, the cylindrical body 11 is covered outside the top heating pipe 331, and the water inlet end of the outlet pipe 32 is inserted into the cylindrical body 11 from the bottom opening of the cylindrical body 11. Existing electric water heaters, in order to meet different bathing needs, need to be equipped with multiple heating tubes, and select corresponding heating tubes to work or select multiple heating tubes to work in combination according to different needs of users. Among them, the top heating tube on the top floor is closer to the The water inlet of the water o...

Abstract

The invention provides a hot water gathering structure and an electric water heater. The hot water gathering structure comprises a cylindrical body used for covering an electric heating pipe, the bottom of the cylindrical body is open to form a bottom opening, the upper end of the cylindrical body is provided with a top opening, and the water inlet end of a water outlet pipe is inserted into the cylindrical body from the bottom opening. According to the hot water gathering structure, the hot water gathering structure is arranged outside the electric heating pipe in a sleeving mode, hot water heated by the electric heating pipe cannot flow freely, the heat exchange amount of the hot water around the electric heating pipe and nearby cold water is reduced, the high-temperature hot water is gathered near a water inlet of the water outlet pipe, the hot water of the electric heating pipe is effectively discharged, and the hot water outlet amount is increased.

Description

technical field [0001] The invention relates to the technical field of electric water heaters. Background technique [0002] At present, the heating methods of water storage water heaters include the following three types: submerged type, top-layer type and semi-tank type. Among them, the submerged type is a heating method in which the heating tube is placed at the bottom of the inner tank; the top-layer type is a heating method in which the heating tube is placed The heating method on the top layer of the inner tank; the half tank type is a heating method in which the heating tube is set in the middle of the inner tank. Among them, the submerged heating method can only heat the water in the entire inner tank, and cannot heat in a targeted manner. The heating time is long and there is a certain waste of energy consumption. The effective heating part of the top heating pipe is only the area of ​​the top heating wire, and the top heating pipe is open in the inner tank, it wil...
