Thus, when the card slot 1211 is engaged with the card 210, the card section 212 can extend out of the electrical cavity 120 from the card slot 1211, and the connecting corner of the connecting section 211 and the card section 212 is engaged with the lower side of the card slot 1211, and the electronic control box 200 is engaged with the card slot 1211.

In some embodiments, in order to prevent the latch 210 from scratching or scratching the latch groove 1211 during installation or removal, the connecting section 211 is connected to the first end 2121 in an arc shape at a corner thereof. Optionally, the edges of the second end 2122 of the connecting segment are rounded.

Fig. 7 is a partially enlarged schematic view of the housing of fig. 2 provided by an embodiment of the disclosure.

As shown in fig. 7, in some embodiments, the lower side of the slot 1211 includes an abutting surface 12111 and a guiding surface 12112 connected to each other, the abutting surface 12111 is parallel to the connecting section 211 and can abut against the connecting section 211, and the guiding surface 12112 is inclined downward from the inner wall side of the rear plate 121 to the outer wall side of the rear plate 121. The inner wall of the rear side plate 121 refers to a side of the rear side plate 121 facing the inside of the appliance cavity 120, that is, a side facing the electronic control box 200, and the outer wall of the rear side plate 121 is opposite to the inner wall of the rear side plate 121.

Optionally, the abutting surface 12111 is parallel to the connecting section 211, so that when the electronic control box 200 is snapped into the slot 1211, the connecting section 211 can abut against the abutting surface 12111. Alternatively, the guide surface 12112 is provided obliquely downward from the inner wall side of the rear side plate 121 to the outer wall side of the rear side plate 121. Thus, the latch 210 can enter the slot 1211, and after the latch 210 extends out of the slot 1211, the second end 2122 can move along the guide surface 12112, so that the electronic control box 200 can be conveniently clamped in the slot 1211. Optionally, the second end 2122 is provided with an inclination angle matching the guide surface 12112 on the side facing the rear plate 121 to improve the engagement between the latch 210 and the latch 1211.

Alternatively, the clamping section 212 is fixedly connected to the connecting section 211 at an angle. In the case of a perpendicular fixed connection of the clamping section 212 and the connecting section 211, the distance between the first side 2123 and the rear side 121 is at least equal to the length of the connecting section 211; in the case of the fixed connection of the clamping section 212 and the connecting section 211 at an obtuse angle, the distance between the first side 2123 and the rear side 121 is greater than the length of the connecting section 211.

In some embodiments, the distance between the first side 2123 and the rear side panel 121 is greater than or equal to the thickness of the rear side panel 121. Thus, the degree of fitting in the case of securing the engagement of the latch 210 with the latch groove 1211 can be improved.
