Abstract
The utility model relates to a dish washer drain pump. Comprises a shell (1), a water inlet (3) and a water outlet (4) which are arranged on the shell (1), and a check valve (5) which is arranged in the water outlet (4); it is characterized in that the shell (1) is provided with an air outlet (2) which is communicated with the pump cavity (11) and discharges the air in the pump cavity (11). The utility model discloses owing to adopt the structure that is equipped with the gas vent on the drainage pump casing, after the intraoral check valve of delivery port was pushed down sealedly by the water column of the take the altitude of delivery port opposite side, pump chamber memory air will be discharged through the gas vent, and the drainage is not smooth because of pump chamber memory air can not appear in the drain pump like this, and in addition, the gas vent is established in the position that is higher than the pump chamber on the pump body, because the pressure action makes gaseous come-up, more thoroughly that pump chamber memory air will discharge, and the drain pump drainage is more smooth.
Description
Technical field
The utility model relates to a kind of dish washing-machine water-draining pump, belongs to the improvement technology of dish washing-machine water-draining pump.
Background technique
The draining pump of existing dishwasher, generally after draining, water in the waste pipe can be pushed down the safety check in the draining pump water outlet, cause draining pump water outlet one side to be lived by check valve seal, after intaking once more, because air is brought in water inlet into, and air is owing to can't discharge from water outlet again, cause air to remain in the draining pump pump chamber, draining has some setbacks when making draining.
The model utility content
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of and pump chamber internal memory air can be discharged, and draining is dish washing-machine water-draining pump smoothly.
In order to achieve the above object, the utility model is achieved in that and comprises housing, is located at water intake and water outlet on the housing, is located at the safety check in the water outlet; Also be provided with the relief opening that the air in the pump chamber is discharged that is communicated with its pump chamber on its middle shell.
Above-mentioned relief opening is located at any position that is higher than pump chamber on the housing.
The utility model is owing to adopt the structure that is provided with relief opening on the draining pump housing, after the safety check in the water outlet is pushed down sealing by the water column of the certain altitude of water outlet opposite side, pump chamber internal memory air will be discharged by relief opening, draining pump can impeded drainage not occur because of pump chamber internal memory air like this, in addition, relief opening is located at the position that is higher than pump chamber on the pump housing, because the pressure effect makes the gas come-up, it is more thorough that pump chamber internal memory air will discharge, and the draining pump draining is more smooth and easy.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the utility model embodiment 2 a structural representation.
Embodiment
Embodiment 1:
Structural representation of the present utility model as shown in Figure 1, include housing 1, be arranged on water intake 3 and water outlet 4 on the housing 1, be located at the safety check 5 in the water outlet 4, in order to ensure the air in the draining pump pump chamber 11 being discharged, also be provided with on the housing 1 relief opening 2 that pump chamber internal memory air is discharged that is communicated with its pump chamber 11.Water intake 3 links to each other with the drainage system pipeline respectively with water outlet 4.
For more thorough pump chamber 11 internal memory air are discharged, in the present embodiment, relief opening 2 is located on the water outlet pipe that is higher than pump chamber 11, and relief opening 2 is communicated with pump chamber 11.
Structural representation of the present utility model as shown in Figure 2, wherein, relief opening 2 is opened on the body of housing 1, is positioned at the highest point of pump chamber 11.Other structure is identical with embodiment 1.
The utility model in use, when draining pump after the draining first time, because safety check blocks water outlet one side part backwater, form certain pressure in water outlet one side, after reaching in the water inlet process next time, because air is brought in water inlet into, and safety check is pushed down by the certain altitude water column of water outlet opposite side, water outlet is sealed, will air be arranged at the pump chamber internal memory like this, owing to be provided with relief opening on the draining pump housing, the air in the pump chamber will be discharged by relief opening, draining pump can impeded drainage not occur because of pump chamber internal memory air like this, in addition, relief opening is located at the position that is higher than pump chamber on the pump housing, because the pressure effect makes the gas come-up, it is more thorough that pump chamber internal memory air will discharge, and the draining pump draining is more smooth and easy.
Claims (2)
1, a kind of dish washing-machine water-draining pump comprises housing (1), is located at water intake (3) and water outlet (4) on the housing (1), is located at the safety check (5) in the water outlet (4); It is characterized in that on housing (1), being provided with the relief opening (2) that the air in the pump chamber (11) is discharged that is communicated with its pump chamber (11).
2, dish washing-machine water-draining pump according to claim 1 is characterized in that above-mentioned relief opening (2) is located at any position that is higher than pump chamber (11) on the housing (1).
