The control panel seat 2 is provided with a through hole 21, and the pressure guide pipe 4 penetrates through the through hole 21 and enters the box body 1.
A water level installation seat 5 is arranged on the control panel seat 2, wherein the water level installation seat 5 comprises an installation seat body 51, a fixing structure arranged on the installation seat body 51 and used for fixing the water level sensor 3, and an accommodating groove 52 used for protecting the pressure pipe 4, the water level sensor 3 is fixed at the fixing structure, and the pressure pipe 4 penetrates through the accommodating groove 52.
In this embodiment, the water level installation seat 1 is arranged, so that the pressure guiding pipe 40 passes through the accommodating groove 52, that is, an end part of the pressure guiding pipe 4 connected with the air tap 32 is located in the accommodating groove 52, and the pressure guiding pipe 4 is prevented from being bent or damaged due to extrusion of an external object due to protection of the accommodating groove 52, so that accuracy of pressure transmission of the pressure guiding pipe 4 is ensured, and accuracy of the water level sensor is ensured; meanwhile, the water level sensor 3 is arranged at the fixed structure of the water level mounting seat, so that the water level sensor 3 and the water level mounting seat 1 are fixed firmly.
In this embodiment, referring to fig. 9, the water level mounting base 1 is fixed on the control panel base 2 by screws, so that the water level sensor 1 can be mounted on the water level mounting base 5, and then the water level mounting base 2 is fixed on the control panel base of the washing machine, so that the water level sensor is convenient to mount. In this embodiment, the bottom surface of the water level installation seat body 51 is provided to facilitate the firmness of fixing with the control panel seat 2.
To facilitate the description of the receiving groove 52, one end of the receiving groove 52 near the fixing structure is defined as an inlet end 521, and the other end is defined as an outlet end 522, as shown in fig. 6. In order to increase the protection of the accommodating groove 52 on the pressure guiding pipe 4 and avoid the pressure guiding pipe 4 being extruded by an external object before passing through the through hole 21 on the control panel seat 2 and entering the box body 1, the outlet end 522 of the accommodating groove 52 is arranged above the through hole 21, that is, the pressure guiding pipe 4 is ensured to pass through the accommodating groove 52 and directly enter the through hole 21, as shown in fig. 4.

Thus, the bottom 523 of the accommodating groove 52 is attached to the pressure pipe 4, and the accommodating groove 52 is further provided with two side walls 524 extending upwards; the accommodating groove 52 protects the pressure guiding pipe 4 by being pressed by an external object, and is provided with an arc-shaped bottom 523; when the pressure fluctuation transmitted in the pressure guide pipe 4 is large, the fluctuation of the pressure guide pipe 4 is caused, and the part of the fluctuation of the pressure guide pipe 4 in the accommodating groove 52 is transmitted to the accommodating groove 52, so that the stability of the pressure guide pipe 4 is improved; or the receiving groove 52, limits the freedom of movement of the pressure pipe 4, and increases the stability of the pressure pipe 4.
When the pressure pipe 4 transmits pressure, particularly, the axial force applied to the fixing structure 9 between the pressure pipe 4 and the air faucet 32 mainly acts on the fixing structure, which easily causes the fixing between the pressure pipe 4 and the air faucet 32 to be loosened, and affects the precision of the water level sensor. In this embodiment, the axial direction of the inlet end 521 of the accommodating groove 52 and the axial direction of the outlet end 522 form a certain included angle; that is, the accommodating groove 52 has a bend in the length direction, so that the pressure pipe 4 has a bend in the accommodating groove 52, that is, when the axial force applied to the pressure pipe 4 is transmitted upward, after entering the outlet end 522, due to the accommodating groove 52 having a bend in the length direction, the axial force is applied to the side wall 524 of the accommodating groove 52 at the bend, so that the axial force reaching the fixing structure 9 is small. The axial direction of the inlet end 521 and the axial direction of the outlet end 522 of the accommodating groove 52 form a certain included angle; the axial force applied to the fixing structure 9 between the pressure guide pipe 4 and the air tap 32 is reduced, the sealing performance between the pressure guide pipe 4 and the air tap 32 is improved, and the precision of the water level sensor 3 is guaranteed. Preferably, the axial direction of the inlet end 521 of the receiving groove 52 is perpendicular to the axial direction of the outlet end 522, as shown in fig. 6, so that the axial force applied to the pressure pipe 4 reaches the bending portion of the receiving groove 52 and is almost completely transmitted to the sidewall 524 of the receiving groove 52, thereby further reducing the axial force applied to the fixing structure 9 between the pressure pipe 4 and the air faucet 32.
