Abstract
The utility model relates to a double circulation wave wheeled type washing machine, which is composed of a washing bucket, a flow restraining protecting hood, a wave wheel, an electric motor, etc. In the utility model, a spiral curved surface type wave wheel which can rotate in a normal and a reverse directions causes the washing liquid to generate the double circulation, the flow restraining protecting hood is used for restraining the spiral flow of the washing liquid and isolating the friction of the wave wheel to the washing. The washing liquid can repeatedly scour and wash the washing in a double direction, which eliminates the twisting phenomenon of the washing, and reduces the abrasion of the washing. Therefore, the utility model has the advantages of high cleaning rate, short washing time, and small abrasion.
Description
The utility model relates to a kind of pulsator washing machine with two-way circulation.
The impeller of existing pulsator washing machine is the disk that a upper surface has three or four ribs.The washing process of washing machine is: during motor drives impeller high speed rotating, near the impeller cleaning solution produces a radial velocity on the one hand under the effect of centrifugal inertial force, produce a tangential velocity with the impeller rotation on the other hand, move to the impeller outer rim and get rid of to the bucket wall, rise to liquid level along the bucket wall again then with the aggregate velocity of maximum.Because impeller is formed centrally low-pressure area in when rotation, under the effect of pressure reduction, the cleaning solution of upper strata liquid level flows to impeller downwards along the impeller center again, make cleaning solution form down → on → under circulation, also form the eddy flow of a horizontal direction simultaneously.The shortcoming of this washing machine is: no matter the impeller forward or reverse, the circulation direction of cleaning solution is constant unidirectional circulation, scouring effect to washings is bad, simultaneously, atwirl impeller has wearing and tearing to washings, the level rotary flow that produces makes the washings strand together, so wearing and tearing are big, cleans ability.
The purpose of this utility model is to improve the above-mentioned shortcoming of pulsator washing machine, and a kind of double loop pulsator washing machine is provided, and makes cleaning solution produce two-way circulation in bucket, strengthens the ability of cleaning, reduce wear, the elimination washings revolve the strand phenomenon.
The purpose of this utility model realizes with lower device.This device has a wash bucket, in the bucket spiral camber formula impeller and suppression guard shield is installed, and motor drives impeller by belt transmission, and motor can be realized forward and backward under the control of timer.Impeller after the improvement has radial and axial two-way function, during the impeller forward or reverse, drives cleaning solution radially or axial flow, makes cleaning solution form two-way circulation in bucket.The level rotary flow that the suppression guard shield of setting up is mainly used to suppress impeller to be produced when just changeing is isolated impeller and washings simultaneously.
By accompanying drawing an embodiment of the present utility model is made a detailed description below.
Fig. 1 is a transmission schematic diagram of the present utility model.
Fig. 2 is the three-dimensional sketch of the impeller of current when washing valve open.
Fig. 3 is the cleaning solution circulation schematic diagram of impeller when just changeing.
Cleaning solution circulation schematic diagram when Fig. 4 is the impeller counter-rotating.
Fig. 5 is the three-dimensional sketch of suppression guard shield.
Spiral camber formula impeller (3) is installed on the impeller axle (4) of wash bucket (1) inner bottom surface, and is separated with suitable distance with inner bottom surface, and suppression guard shield (2) is covering impeller (3), is fastened on the inner bottom surface of bucket (1).Spiral camber formula impeller (3) after the improvement is formed (respectively being four among the figure) by spiral camber more than two or two (7) and valve (8), valve (8) is hinged on the high-end of spiral camber (7), can free opening and closing, roll in bucket in order to improve level rotary flow and to help washings, radially be provided with a back rake angle α along impeller (3), be provided with an angle of inclination beta vertically.Suppression guard shield (2) is by the suppression sheet (9) more than four or four, and wire Intranet (10) constitutes, and suppression sheet (9) has reflex to level rotary flow, and the purpose of metal Intranet (10) is to stop washings to enter impeller.
When impeller (3) when just changeing, valve (6) is closed automatically, and its effect is identical with existing pulsator washing machine, and cleaning solution forms circulation shown in Figure 3 in bucket, and level rotary flow is repressed like this; The aggregate velocity direction of the cleaning solution that impeller (3) throws away when just changeing and impeller (3) radially have a drift angle, because suppression sheet (9) has suitable width, so the part of cleaning solution rushes at suppression sheet (9) and is reflected away, another part is not still gone out with the aggregate velocity direction by suppression sheet (9) reflection, then, two strands of liquid streams that are reflected and are not reflected intersection again collide, and synthetic new radial velocity rushes at a barrel wall, and level rotary flow is eliminated.
When impeller (3) reversed, cleaning solution flowed into from the lower edge of impeller (3), flowed along the direction shown in the black arrow among Fig. 2 then, washed valve (8) open and rose along spiral camber (7), formed circulation shown in Figure 4.So far, cleaning solution has been finished two-way circulation in bucket.
Claims (4)
1, a kind of pulsator washing machine with two-way circulation, it comprises wash bucket (1) and impeller (3), it is characterized in that having on the impeller (3) spiral camber (7) and valve (8) more than two or two, valve (8) is hinged on the high-end of spiral camber (7), and suppression guard shield (2) is made of suppression sheet (9) more than four or four and metal Intranet (10).
2, washing machine according to claim 1 is characterized in that spiral camber (7) and valve (8) respectively are four.
3, washing machine according to claim 1 is characterized in that valve (8) radially has a back rake angle α along impeller (3), has an angle of inclination beta vertically.
4, washing machine according to claim 1 is characterized in that suppression sheet (9) is eight.
