Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to an instant water heater. Background Art

[0002] A water heater generally consists of a water pipe and a heating pipe. The existing water heaters generally adopt a spiral water pipe and a straight heater. The spiral water pipe is wound around the outer periphery of the straight heater, and the heat released by the straight heater is transferred from the inner side wall of the heating pipe to the inside of the water pipe. However, the heat transfer efficiency of this type of water heater is relatively low.

[0003] For example, a flow-through water heater disclosed in the patent with the publication number CN213713537U. Referring to it Figure 1 In this technical solution, the spiral water pipe is wound around the outer periphery of the heating pipe. The heat released by the heating pipe can only enter the water pipe from the inner side wall of the water pipe and cannot enter the water pipe in all directions sufficiently. In addition, there is a certain distance between each spiral of the spiral water pipe, and the heat released by the heating pipe will be dissipated outside the water pipe from this distance. The heat released by the heating pipe cannot be fully absorbed by the water pipe, and there is still room for improvement in the heat transfer efficiency.

[0004] Therefore, there is an urgent need for an instant water heater. Content of the Utility Model

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide an instant water heater with good heat transfer.

[0006] The technical solution adopted by the utility model to solve the problem is: an instant water heater, including a water pipe and a heating pipe. The middle part of the water pipe is bent to form a spiral part, and the middle part of the spiral part has a first cavity; the middle part of the heating pipe is bent to form a bent part, and the bent part is installed in the first cavity; it also includes a die-cast aluminum layer, and the die-cast aluminum layer wraps the spiral part and the bent part.

[0007] As a further improvement of the above technical solution, there is a gap between the spiral part and the bent part, and the die-cast aluminum in the die-cast aluminum layer fills the gap.

[0008] As a further improvement of the above technical solution, the two ends of the water pipe are respectively an inlet part and an outlet part. The inlet part extends out from the left side surface of the die-cast aluminum layer, and the outlet part extends out from the right side surface of the die-cast aluminum layer.

[0009] As a further improvement of the above technical solution, the spiral part is elliptical, and the number of spiral turns of the spiral part is one.

[0010] As a further improvement of the above technical solution, the bent portion is U-shaped, and both ends of the heating pipe extend out from the upper side surface of the die-cast aluminum layer.

[0011] As a further improvement of the above technical solution, the middle part of the bent portion has a second cavity, and the die-cast aluminum layer is provided with a strip-shaped hole, and the strip-shaped hole is located in the second cavity.

[0012] The beneficial effects of the present utility model are as follows: by bending the middle part of the heating pipe into a bent portion and placing the bent portion in the spiral portion of the water pipe, both the bent portion and the spiral portion are wrapped by the die-cast aluminum layer, so that the heat released by the heating pipe can fully enter the die-cast aluminum layer, and the heat in the die-cast aluminum layer can fully enter the water pipe, improving the heat transfer efficiency.
