Abstract

The utility model discloses an electrically controlled double-effluent washing pump, which belongs to a water pump, and aims at providing a washing pump with compact structure and simple control system. The technical proposal is that the washing pump comprises an enclosure, an electrical motor provided with an impeller and a controller; a water inlet (3), two water outlets (5) and a socket (7) are arranged on the enclosure (2), and the socket is provided with a positive inserting sheet (8), a reverse inserting sheet (9) and a cathode inserting sheet (10); the electrical motor (1) fixed in the enclosure (2) is electrically connected with the controller (6). The washing pump of the utility model has the advantages of lower installing workload, installing space conservation and low cost, etc., and can be widely applied to various medium-high grade cars.

Description

The two water outlet washer pumps of electric-controlled type

Technical field:

The utility model relates to a kind of water pump, relates in particular to a kind of washer pump that is used to clean windshield.

Background technique:

At present, the washer pump of windshield has only a water outlet mostly, can not take into account the cleaning of forward and backward windshield, and the needs that two washer pumps and two cover control gear could satisfy forward and backward windshield cleaning must be installed for this reason; Not only cause waste, but also brought defectives such as installation workload increase, the increase of required installing space, manufacture cost rising.

Summary of the invention:

At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of compact structure, the two water outlet washer pumps of the simple electric-controlled type of control system.

To achieve these goals, the utility model by the following technical solutions: it comprises case, the motor and the controller of impeller is housed; Case is provided with a water intake, two water outlets and a socket, and this socket is provided with forward inserted sheet, reverse inserted sheet and negative pole inserted sheet; The motor that is fixed in the case is electrically connected with controller.

Compared with the prior art, the utility model is owing to be provided with the water outlets that can two be connected with the windscreen wiper system that cleans forward and backward windshield respectively on case, and adopt a cover control gear to realize the forward and backward of motor, therefore only just can satisfy the needs that clean forward and backward windshield with a washer pump, both reduce cost, reduced installation workload, saved installing space again.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In Fig. 1, controller 6, the motor 1 that impeller 4 is housed are fixed in the case 2, and motor 1 is electrically connected with controller 6; Case 2 is provided with a water intake 3, two water outlets 5 and sockets 7, and this socket is provided with a forward inserted sheet 8, a reverse inserted sheet 9 and a negative pole inserted sheet 10.

Working principle: as shown in Figure 2, when reverser 11 contacts with forward inserted sheet 8, electric current enters motor 1 from flow through reverser 11, forward inserted sheet 8, switch contact 17, first relay switch 18 of the positive pole of power supply, flow back to the negative pole of power supply and form the closed-loop path through second relay switch 19, switch contact 15 then, motor 1 impeller 4 is made forward rotation and water is pumped from a water outlet 5, be connected with the windscreen wiper system that is positioned at front windshield by conduit again, thus the cleaning of realization front windshield; When reverser 11 contacts with reverse inserted sheet 9, because of first relay 12, second relay 13 gets electric and makes first relay switch 18, second relay switch 19 respectively with

switch contact

16,14 contacts, so electric current is from the positive pole of the power supply reverser 11 of flowing through, reverse inserted sheet 9, switch contact 14, second relay switch 19 enters motor 1, then through first relay switch 18, switch contact 16 flows back to the negative pole of power supply and forms the closed-loop path, motor 1 impeller 4 is made backward rotation and water is pumped from another water outlet 5, be connected with the windscreen wiper system that is positioned at rear seat windscreen by conduit again, thus the cleaning of realization rear seat windscreen.

Claims

1. two water outlet washer pumps of an electric-controlled type comprise case, the motor and the controller of impeller are housed; It is characterized in that: case (2) is provided with a water intake (3), two water outlets (5) and a socket (7), and this socket is provided with forward inserted sheet (8), reverse inserted sheet (9) and negative pole inserted sheet (10); The motor (1) that is fixed in the case (2) is electrically connected with controller (6).
