In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

In view of the above, the present invention provides a chassis assembly, referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the present invention, in which a water level switch is disposed in a water containing tank, and in this embodiment, the chassis assembly includes:

a chassis 10 provided with a water tank 11; and

a water level switch 20 provided in the water receiving tank 11 and including a float 210 to float up and down along with the water surface in the water receiving tank 11;

the shortest distance between the outer edge of the float 210 and the tank side wall of the water containing tank 11 is greater than or equal to 7 mm; and/or the distance between the lower limit position of the float 210 and the bottom wall of the water containing tank 11 is greater than or equal to 6 mm.

In the technical scheme of the utility model, the minimum safety clearance between the floater 210 and the side wall and the bottom wall of the water containing tank 11 is limited, so that even if the water level switch 20 is in an abnormal condition, the floater 210 is not easy to interfere with the side wall or the bottom wall of the water containing tank 11, the problem that the floater 210 cannot normally work is caused, and the risk that the first water level switch 21 fails in the abnormal condition is reduced. It can be understood that the air conditioner includes, but is not limited to, storage transportation, road transportation, and installation and fixation from the factory to the installation and use, and the air conditioner may have abnormal shaking in these links, which causes the problem of abnormal position deviation of the float 210 of the water-fetching switch, and thus causes the friction interference between the float 210 and the side wall or the bottom wall of the water containing tank 11, which causes the float 210 to be stopped at an abnormal position state and unable to recover, and further causes the problem that the float 210 cannot normally work. And the water level switch 20 is usually in the air conditioner outdoor unit, so that it is not easy to check whether it is in a normal position state, that is, it is not easy to find the problem of the function failure of the water level switch 20 in time. It is necessary to define a minimum safety clearance between the float 210 and the side wall and the bottom wall of the water receiving tank 11 to ensure that the water level switch 20 can operate normally even if an abnormal condition is encountered, thereby reducing the risk of malfunction of the first water level switch 21.
