Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, the water tank type cleaning machine comprises a water tank body 1, a door cover 2, a water discharge cup 3, a cleaning pump 4 and a spray arm 5.

The upper part of the water tank body 1 is provided with an opening and a door cover 2, and a spray arm 5 is arranged inside the water tank body. The top of the lower water cup 3 is opened to form a lower water opening 31, the lower water opening 31 is communicated with the water tank body 1, and the bottom of the lower water cup 3 is provided with a water outlet 32. The cleaning pump 4 is positioned at the bottom of the water tank body 1, the water outlet of the cleaning pump is connected to the spray arm 5 in the water tank body, and the return water is pumped into the spray arm 5.

Referring to fig. 1 to 4, a main return port 33 and an auxiliary return port 34 are arranged on the side wall of the lower cup 3, the main return port 33 is arranged at the bottommost part of the side wall, the auxiliary return port 34 is arranged above the main return port 33 and clings to the upper part of the inner wall of the return pipe 6, the main return port 33 and the auxiliary return port 34 are communicated with the water inlet of the cleaning pump 4 through the return pipe 6, the lower part of the inlet end of the return pipe 6 is concave towards the pipe and is connected below the return port of the lower cup to adapt to the position of the main return port 33. When the cleaning pump 4 works to suck water above the main return port 33, water flow can be supplemented from the auxiliary return port 34 in time, the water enters the cleaning pump 4 and the spray arm 5 along the upper space of the return pipe 6 to circulate, local vacuum negative pressure is avoided, and then steam is prevented from impacting the return pipe 6 to generate noise.

As a better implementation mode, the main return port 33 is a flat opening, and the vertical distance of the flat opening of the main return port 33 is 5mm, so that the distance from the main return port 33 to the water surface in the water tank body 1 is maximized, namely the cleaning pump 4 is positioned at the deepest part of the cleaning machine to pump water, the influence of the water quantity in the lower water cup 3 on the water return effect can be reduced to the maximum degree, the water return is effectively ensured to be smooth, meanwhile, the gas in the vortex of the lower water port 31 at the upper part of the lower water cup 3 is reduced to enter the main return port 33, the water return pipe 6 and the cleaning pump 4, and the noise caused by the water-gas friction during the circulating water flow.

The relationship between the sectional area a of the main return port 33 and the sectional area B of the water inlet of the washer pump is set to 0.3B. The cleaning machine has the advantages that the spraying force of the cleaning pump on the lift and the spraying arm can be effectively guaranteed, the amount of return water can be effectively limited, the phenomenon that the water in the lower water cup 3 is drained to cause return water and the spraying effect is suddenly small is avoided, the cleaning effect of the cleaning machine is effectively guaranteed, meanwhile, the amount of sucked gas is reduced, and the return water noise is reduced.

As an example, as shown in fig. 2 to 4, the upper side of the main return port 33 is closely attached to the upper side of the inner wall of the return pipe 6, and the auxiliary return port 34 is a circular hole having a cross-sectional area C of 0.3A (a is the cross-sectional area of the main return port), so that the control of the amount of return water is not greatly affected while the return water is replenished.

Referring to fig. 1 to 4, the cleaning pump 4 pumps the water in the lower water cup 3 and the water tank body 1 to the spray arm 5 from the main return port 33 and the auxiliary return port 34, the spray arm 5 sprays the water to the objects to be cleaned in the water tank body 1 for cleaning, and the water is collected at the bottoms of the lower water cup 3 and the water tank body 1 again.

As another example, as shown in FIG. 5, the flat opening of the main return opening 33 of the lower cup 3 is 20mm in vertical distance. The relationship between the sectional area a of the main return port 33 and the sectional area B of the water inlet of the washer pump is set to 0.5B. The auxiliary return port 34 is an elliptical hole with a sectional area C equal to 0.2A (a is the sectional area of the main return port), and is communicated with the main return port 33 through a vertical slit-shaped connector 35, so that water flow is directly supplemented above the return pipe during water return, and the return is further ensured to be smooth and avoid vacuum negative pressure.

In addition, the auxiliary water return opening 34 may also be in the shape of a slit.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
