However, it is not limited thereto, and the fitting projections 43a may be formed to be spaced apart from a plurality of dogs in the circumferential direction.

Accordingly, the adapter body 41a and the fluid body 31a can be more firmly coupled.

On the other hand, the fluid body (31a) may include a locking protrusion (39a) protruding from the outer circumferential surface. In addition, the adapter body 41a may include a stopper 49a that protrudes from the inner circumferential surface and is provided to be caught by the protrusion 39a so as to restrict rotation when rotationally coupled with the fluid body 31a.

The stopper 49a and the locking protrusion 39a may be formed at predetermined positions. Specifically, the stopper 49a and the locking protrusion 39a may be formed at positions where the amount of rotation can be appropriately adjusted when the adapter unit 40a and the moving unit 30a are rotated and assembled. For example, after inserting the fitting protrusion 43a into the insertion groove 35a, when rotating to insert into the fitting groove 36, the stopper 49a is provided so as to catch the locking protrusion 39a at an appropriate position .

Due to this, excessive rotation of the adapter unit 40a can be prevented. As a result, it is possible to prevent damage to the joint between the adapter body 41a and the moving body 31a, and to prevent damage to the sealing member 60 disposed between the adapter unit 40a and the heating unit 20a, which will be described later. can be minimized.

Meanwhile, a sealing member 60a for sealing between the heating unit 20a and the adapter unit 40a may be further included.

For example, the sealing member 60a may be provided to seal between one end or the other open end of the heating body 21a and the adapter body 41a. Watertightness of the hot water generating module 10a may be improved after assembly by the sealing member 60a.

Specifically, the adapter unit 40a may include a support surface 47a formed stepwise on the inner circumferential surface of the adapter body 41a so that the end of the heating body 21a is caught.

And the sealing member (60a) has a contact surface (61a) in close contact with the support surface (47a) and a sealing groove (63a) formed to open in a direction toward the heating body (21a) so that the end of the heating body (21a) is fitted. can include

For example, the sealing member 60a may be formed in a ring shape to be fitted to the end of the heating body 21a. And, on a cross section cut by an imaginary plane parallel to the axial direction, the sealing member 60a may have a U-shaped cross section open toward the heating body 21a. For example, the sealing member 60a may be made of an elastic material such as rubber. However, the shape and material of the sealing member 60a are not limited thereto.

Specifically, the sealing member 60a may include a sealing groove 63a concavely formed to open in a direction toward the heating body 21a, and a contact surface 61a, which is a surface opposite to the sealing groove 63a. The contact surface 61a may be provided to be in close contact with the support surface 47a of the adapter body 41a, and the sealing member 60a in a state where the heating body 21a is inserted into the sealing groove 63a is the heating body ( 21a). Accordingly, when the moving part 30a and the adapter part 40a are coupled, the sealing member 60a can seal between the heating part 20a and the adapter part 40a.
