The edge of the opening may also directly abut against the inner side of the front panel 102 to form a relatively enclosed control board cavity.

[0032] Specifically, both sides and the bottom of the bracket component 300 are connected to the main housing 100. The first side wall 103 and the second side wall 104 of the main housing 100, which are opposite to each other, are respectively provided with a first reinforcing rib 111 and a second reinforcing rib 112. Both sides of the control board mounting frame 360 are provided with mounting frame limiting grooves 362.

The water circuit board component 200 and the bracket component 300 are connected to form a water circuit board integrated component. The water circuit board integrated component is integrally inserted into the main housing 100 from the installation opening 101, and the water circuit board component 200 closes the installation opening 101. In this embodiment, the entire back surface of the main housing 100 is provided as the installation opening 101. Four sides of the water circuit board component 200 are connected to the inner side wall of the main housing 100. The main housing 100 adopts an integrally formed structure.

The first limiting slot 211 is clamped on the first reinforcing rib 111, and the second limiting slot 212 is clamped on the second reinforcing rib 112. The installation stability of each component is good, without the need for excessive screw and buckle structure designs, which is beneficial to further improving the assembly efficiency and reducing the cost. Moreover, through the arrangement of the reinforcing ribs, the structural strength of the main housing 100 is effectively improved, preventing the main housing 100 from deforming, and the structural reliability is higher.

[0037] Specifically, in this embodiment, the lower side wall (bottom wall) of the main housing 100 is defined as the third side wall 105, and the upper side wall (top wall) of the main housing 100 is defined as the fourth side wall 106. The first side wall 103 and the second side wall 104 are arranged opposite to each other, and the third side wall 105 and the fourth side wall 106 are arranged opposite to each other. The first side wall 103, the second side wall 104, the third side wall 105, and the fourth side wall 106 enclose a rectangular frame.

There is a certain gap between the bottom of the bracket component 300 and the inner bottom of the main housing 100. Even if there is accumulated water in the main housing 100 due to water leakage, it can prevent the accumulated water from directly soaking the electrical components on the bracket component 300. The top of the water circuit board component 200 is provided with a fourth limiting groove 214, and the fourth side wall 106 of the main housing 100 is provided with a fourth reinforcing rib 114. The fourth reinforcing rib 114 extends into the main housing 100 along the installation opening 101, and the fourth reinforcing rib 114 is stuck in the fourth limiting groove 214. In this way, the four directions of the water circuit board integrated component are assembled and constrained through the rib-groove matching structure, its internal structure is stable, and the water circuit board component 200 is integrally sealed to the installation opening 101 on the back of the main housing 100.

The color, surface texture, and pattern of the patch can be the same as those of the outside of the main housing 100, so that the appearance of the product is highly consistent.

[0038] Specifically, one end of the bracket member 300 is provided with a supporting groove 351. A part of the waterway plate member 200 is inserted into the supporting groove 351 and is limited by the supporting groove 351. The bracket member 300 is provided with locking members on both sides and / or the bottom of the supporting groove 351 for locking the waterway plate member 200 to the bracket member 300, so that the fixing reliability between the bracket member 300 and the waterway plate member 200 is good.

[0039] Specifically, the main housing 100 further has a third side wall 105. The third side wall 105 is provided with at least two housing ribs 213. The bottom of the bracket member 300 is provided with at least two bracket ribs 311. The bracket ribs 311 are in contact with the housing ribs 213.
