Description

Technical Field

[0001] The utility model relates to the technical field of electric heaters, and more particularly to a milk and coffee dual-purpose boiler heater. Background Art

[0002] Currently, there are two main ways to add milk to coffee: frothing and hot milk. The frothing method uses high-temperature steam to directly heat the milk, which can only heat one cup of milk at a time. The steam also contains a certain amount of water, which condenses into the milk, reducing its taste. The hot milk method, on the other hand, passes cold milk through a small inner diameter pipe and heats it in a water bath, continuously heating the milk to the target temperature while ensuring that no additional water is added to the milk during the heating process.

[0003] To ensure heating efficiency, the milk pipe of existing dual-purpose milk and coffee boilers must have a thin wall thickness. Most commercially available milk pipes have an outer diameter of 3mm and a wall thickness of 0.25mm or 0.5mm. Because the milk pipe and the faucet need to be brazed, the pipe often deforms and shrinks during the brazing process, affecting assembly feasibility, reducing heating efficiency, and decreasing milk delivery rate, resulting in poor overall performance. Accordingly, the present utility model provides a dual-purpose milk and coffee boiler heater. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a milk and coffee dual-purpose boiler heater, which has the characteristics of a firm structure, easy installation and disassembly, short preheating time, low corrosion resistance and better food safety.

[0005] In order to solve the above technical problems, the purpose of the present invention is achieved as follows: the utility model involves a milk and coffee dual-purpose boiler heater, which includes a heater barrel and a heater barrel cover. The heater barrel cover is symmetrically arranged with two water spouts, and a milk tube extending into the heater barrel is connected in series between the water spouts. The milk tube is coiled into a spiral shape. A heating tube is also provided in the heater barrel. The milk tube is covered with at least two partition brackets extending axially and limiting the pitch of the milk tube.

[0006] The utility model is further configured as follows: the partition bracket is provided with a row of limiting holes which are arranged at equal intervals along the length direction thereof, and the milk tube passes through all the limiting holes in a spiral manner in sequence.

[0007] The utility model is further configured as follows: the partition bracket includes a first bracket plate and a second bracket plate extending along a straight line, a transition plate is connected in series between the tail end of the second bracket plate and the tail end of the first bracket plate, the head end of the first bracket plate is provided with a bending plate bent toward the head end of the second bracket plate, the bending plate is welded to the second bracket plate, and the second bracket plate is provided with a row of limiting teeth extending toward the first bracket plate, one end of the limiting tooth is connected to the second bracket plate, and the other end is against the first bracket plate, the spacing between two adjacent limiting teeth is equal, and each limiting hole is formed between two limiting teeth.

[0008] The utility model is further configured as follows: a process hole is opened on the transition plate.

[0009] The utility model is further configured as follows: the transition plate is integrated with the first bracket plate and the second bracket plate; the bending plate is integrated with the first bracket plate; and the limiting teeth are integrated with the second bracket plate.

[0010] The utility model is further configured such that: the distance A between two adjacent limiting teeth is not less than the outer diameter of the milk tube.

[0011] The present invention is further configured as follows: the thickness B of the first bracket plate and the second bracket plate are both not less than 0.5 mm; and the width C of the limiting teeth is not less than 1 mm.

[0012] The utility model is further configured such that the interval angles between two adjacent separation brackets are equal.

[0013] The utility model is further configured as follows: three separation brackets are arranged on the periphery of the milk pipe and extend in the axial direction and the adjacent separation angles are 120 degrees.

[0014] To sum up, the utility model has the following beneficial effects: the milk and coffee dual-purpose boiler heater involved in the utility model, by installing a customized partition bracket, plays the role of separating, supporting and strengthening the milk pipe, avoiding affecting the assembly feasibility, causing low heating efficiency and reduced milk delivery rate.
