Laundry equipment capable of draining water upwards

Abstract

The invention belongs to the field of washing equipment, and particularly provides upper drainage laundry equipment. The upper drainage laundry equipment is provided with the siphon assembly capable of discharging residual water at the bottom of the filter cavity of the drainage pump, the siphon assembly comprises the water guide pipe and the siphon, the water inlet end of the water guide pipe communicates with the drainage structure at the bottom of the filter cavity of the pump shell, and the water outlet end extends into the water outlet pipe opening of the pump shell through the opening; the siphon is arranged in a drainage pipeline of the upper drainage laundry equipment and arranged in an inverted-U-shaped mode, the water inlet end of the siphon is communicated with the water outlet end of the water guide pipe, the water outlet end of the siphon extends towards the underground drainage opening along the drainage pipeline, and the water outlet end of the siphon is lower than the water inlet end of the water guide pipe so that the whole siphon assembly can form a siphon structure. The water outlet end of the siphon is arranged on the upstream of the water outlet of the drainage pipeline to form pressure difference to promote water to enter the water guide pipe, so that accumulated water in the pump shell is sucked away and drained based on the siphon principle when the accumulated water is accumulated in the pump shell, and the drainage performance of the upper drainage laundry equipment is improved.

Description

technical field [0001] The invention belongs to the field of washing equipment, and specifically provides an upper drainage washing equipment. Background technique [0002] At present, the drainage pump of the washing machine is higher than the floor drain. In theory, it can be drained down. Install a solenoid valve and open it to drain directly when necessary. However, there are two problems with direct drainage. One is that only the upper drainage pipeline of the washing machine can be arranged in some installation environments, and the other is that the drainage speed is slow during natural drainage and the washing cycle will be prolonged. Most of the washing machines on the market now have an upper drainage pipeline. The upper drainage washing machine can be directly inserted into the floor drain to drain, or it can be placed in a high sink for drainage. It has wide adaptability and fast drainage. However, the upper drain washing machine must be provided with a section ...

Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the residual water inside the drainage pump is difficult to discharge after the drainage pipeline of the existing upper drainage laundry equipment returns to water, the present invention provides an upper drainage laundry equipment. The drainage laundry equipment includes an outer cylinder, a drainage pipe connecting the outer cylinder with the outside, and a drainage pump arranged on the drainage pipe. The drainage pump includes a pump casing, an impeller and a filter, and the pump casing is provided with The impeller cavity capable of accommodating the impeller and the filter cavity capable of accommodating the filter, the impeller cavity and the filter cavity communicate with each other, and the pump housing is provided with a water outlet port communicating with the impeller cavity , the upper drainage laundry equipment also includes a siphon assembly and a filter member, the siphon assembly includes a water guide pipe arranged outside the pump casing and a siphon pipe arranged in the drainage pipe, the bottom of the filter cavity is at the lowest position A drainage structure is provided, an opening is provided on the mouth of the water outlet pipe, the water inlet end of the water guide pipe communicates with the drainage structure, and the water outlet end of the water guide pipe extends into the mouth of the water outlet pipe through the opening and connects with the water outlet pipe. The water inlet end of the siphon pipe is connected, the siphon pipe is arranged in an inverted U shape, the siphon pipe extends along the drainage direction of the drainage pipe, and its water outlet end communicates with the outside, and the filter member is arranged in the filter chamber And it is arranged upstream of the water inlet end of the water guide pipe along the water inlet direction of the water guide pipe, the water inlet end of the water guide pipe is higher than the water outlet end of the siphon pipe, and the water outlet end of the siphon pipe is arranged at the drain Upstream of the outlet of the pipe
