[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] The utility model provides a water return elbow with a mounting seat.

[0022] In this embodiment, refer to Figure 1-4 The return elbow with a mounting seat includes a "U"-shaped pipe 1 and a straight pipe 2 vertically connected in the middle of the "U"-shaped pipe, and also includes a mounting seat. One end of the straight pipe is provided with a straight pipe waterway 3 connected to the curved pipe waterway in the "U"-shaped pipe, and the other end is provided with an internal screw hole 4 not connected to the straight pipe waterway 3. The mounting seat includes a connecting column 5 and a mounting plate 6. The connecting column 5 is provided with an external threaded section 7 threadedly connected to the above-mentioned internal screw hole 4, and the mounting plate is provided with a mounting hole 8.
