Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a water heater with a constant temperature preheating structure. Background Technique

[0002] A water heater is a device used to heat water. It can utilize different energy forms, including electricity, natural gas, solar energy or other means to heat water to the usage temperature. Water heaters are usually applied in domestic, commercial and industrial environments to provide hot water required for bathing, washing and cleaning activities. When in use, water is usually directly introduced into the water heater for heating. However, directly heating water consumes a large amount of energy and takes a long time to heat. By installing a heat exchange tube for preheating, after long-term use, a large amount of dirt is easily adhered to the outer wall of the heat exchange tube, which is inconvenient to clean and reduces the heat exchange efficiency.

[0003] Chinese Patent discloses a water heater (authorization announcement number CN209763490U). The patent technology mainly includes a housing and a decorative strip arranged on the housing. There are positioning holes on the housing and positioning posts on the decorative strip. The positioning posts are inserted into the positioning holes to achieve the assembly positioning of the decorative strip and the housing; it also includes a fixing block, and the fixing block is arranged on the positioning post between the housing and the limiting part to achieve the fixed assembly of the decorative strip and the housing.

[0004] However, there are still deficiencies in view of this patent. This patent water heater can not only ensure the assembly level of the decorative strip, but also ensure that there is no step difference between the decorative strip and the sheet metal housing after the water tank is foamed; however, water is directly introduced into the water heater for heating. However, directly heating water consumes a large amount of energy and takes a long time to heat. By installing a heat exchange tube for preheating, after long-term use, a large amount of dirt is easily adhered to the outer wall of the heat exchange tube, which is inconvenient to clean and reduces the heat exchange efficiency. Therefore, those skilled in the art provide a water heater with a constant temperature preheating structure to solve the problems raised in the above background technique.
