Problems solved by technology

Yet this kind of water pump, because the upper shell (rotating spray arm) rotates under the effect of water flow, and the lower shell (flow guide bracket) is suspended and fixed with the applied water tank body, namely the upper shell of the water pump rotates when it is working. The lower casing is fixed, so when the impeller rotates to draw the water in the draining area of ​​the tank upwards and flows into the flow channel of the rotating spray arm, it will encounter greater resistance, causing the drawn water to flow back to the impeller. It reduces the water pumping efficiency of the water pump, increases the power consumption of the water pump, and when it is applied to a sink type washing machine, it will affect the cleaning effect of the washing machine

Embodiment 1

[0025] see Figure 1 ~ Figure 4 , a sink type washing machine, can be used for washing dishes, vegetables, fruits, etc., comprising a sink body 1, and a cover plate 2 rotatably connected to the top of the sink body 1, the sink body 1 can be an ordinary household sink, sink The main body 1 and the cover plate 2 form a washing space for accommodating and washing the above-mentioned dishes, vegetables, fruits and the like.

[0026] The bottom plate 11 of the sink body 1 is concave at least in the central part, and above the concave part of the bottom plate 11, there are drain plates 3 having the same shape as the concave part at intervals, and a plurality of drain plates 3 are provided on the drain plate 3 for draining water. The hole 31 , the space between the drain plate 3 and the concave part of the bottom plate 11 forms a drain area 32 , and the drain plate 3 is flush with other parts of the bottom plate 11 . The outside of the tank body 1, the bottom of the base plate 11 is...

Embodiment 2

[0036] see Figure 5 and Figure 6 , in this embodiment, the difference from the first embodiment above is that the lower cover body 533 of the rotating spray arm 53 is detachably connected to the guide bracket 52, such as through threaded connection, such as the top outer periphery of the guide bracket 52 An external thread 524 is provided, and an internal thread 5331 is provided at a corresponding position on the lower cover body 533 of the rotating spray arm 53, so that the rotating spray arm 53 can rotate synchronously with the guide bracket 52, and the installation, disassembly and manufacture are all very easy. convenient. If the direction of rotation of the rotating spray arm 53 is clockwise (viewed from the top of the tank body 1), right-handed threaded connection is used; Threaded connection, thus can prevent loosening between the rotating spray arm 53 and the guide bracket 52 .

[0037] The lower cover body 533 of the rotating spray arm 53 and the guide bracket 52...

Abstract

The invention discloses an open type water pump. The open type water pump comprises an upper housing, a lower housing and an impeller; the impeller comprises a shaft which is positioned in the center, and a plurality of axially-extended blades which are circumferentially and uniformly distributed on the circumferential surface of the shaft; the blade is axially divided into an upper section and a lower section which are interconnected; an upper storing cavity for storing the upper section of the blade is formed in the upper housing; a lower storing cavity for storing the lower section of the blade is formed in the lower housing. The open type water pump is characterized in that the upper housing and the lower housing synchronously rotate; a bottom ring for mounting and positioning the lower housing is arranged below the lower housing. The invention also discloses a water tank type cleaner using the open type water pump.

Description

technical field [0001] The invention relates to a water pump, especially an open water pump, and the application of the open water pump. Background technique [0002] Before the water pump works, the water pump and the water inlet pipe must be filled with water, and then rely on the high-speed rotating impeller to make the liquid gain energy under the action of inertial centrifugal force to increase its internal pressure. When the impeller rotates rapidly, the blades promote the water to rotate quickly. With the action of centrifugal force flying out of the impeller, after the water in the pump is thrown out, the central part of the impeller forms a vacuum area, and then the water from the water source enters the water inlet pipe under the action of atmospheric pressure (or water pressure), so that Continuous circulation can realize continuous pumping. Because the water pump has the advantages of simple structure, easy operation, easy flow adjustment, and is suitable for th...
