Preferably, described propeller is integrated injection mo(u)lding.
On the other hand, the present invention is by the following technical solutions:
A kind of dish-washing machine, described dish-washing machine has above-mentioned bidirectional rotation and pumps up water propeller.
The invention have the benefit that
The bidirectional rotation provided by the invention propeller that pumps up water has two groups of blades that the hand of spiral is contrary, when propeller is when rotating forward, realize pumping up water by one group of blade therein, when propeller is when reversion, another group blade can be passed through realize pumping up water, reach the effect that bidirectional rotation pumps up water, by current, the forward and reverse of tableware is washed away the effect reaching cleaning, propeller compared to single direction rotation, tableware is had better cleaning effect by the bidirectional rotation provided by the invention propeller that pumps up water, and the uniform fluid flow that pumps up water, dead angle is few, substantially increases the cleaning efficiency of tableware.
Dish-washing machine provided by the invention is provided with above-mentioned bidirectional rotation and pumps up water propeller, and propeller all can realize pumping up water when rotating and reverse, and substantially increases cleaning efficiency and cleaning effect that tableware waits washing, saves the energy, and Consumer's Experience is good.

Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Embodiment one:
Present embodiments provide a kind of bidirectional rotation to pump up water propeller, as shown in Figure 1 to Figure 3, this bidirectional rotation pump up water propeller rotating shaft 1 on be provided with two groups of blades, respectively the first vane group 2 and the second vane group 3. Wherein, the first vane group 2 includes two the first blades 21, and two the first blades 21 are distributed along rotating shaft 1 centrosymmetry, and the first blade 21 is 62 �� relative to the wrap angle sigma of rotating shaft 1. Second vane group 3 includes two the second blades 31, and two the second blades 31 are distributed along rotating shaft 1 centrosymmetry, and the second blade 31 is 26 �� relative to the cornerite �� of rotating shaft 1. Two the first blades 21 are contrary with the hand of spiral of two the second blades 31 and are axially disposed sustained height at rotating shaft 1.
Make when propeller is when rotating forward by said structure, realize pumping up water by the first vane group 2, when propeller is when reversion, can realize pumping up water by second vane group 3 contrary with first vane group 2 hand of spiral, reach the effect that bidirectional rotation pumps up water, so, stirred, by propeller, the current got up and just tableware can be formed forward and reverse washing away, the dirt remaining on tableware can easier be come off, propeller compared to single direction rotation, tableware is had better cleaning effect by the bidirectional rotation propeller that pumps up water that the present embodiment provides, and the uniform fluid flow that pumps up water, dead angle is few, substantially increase the cleaning efficiency of tableware.
First blade 21 and the second blade 31 are respectively provided with higher side and relatively low side, each first blade 21 is all combined together by joint face 4 in higher side with the second blade 31 being adjacent, so ensure that the intensity of blade and rigidity, improve the dynamics of pumping up water of blade, it is greatly improved the structural reliability of propeller, effectively extends the service life of propeller.
In order to improve the structural reliability of propeller further, being connected by round and smooth curved surface with the junction of rotating shaft 1 at blade so that the connection between blade and rotating shaft 1 is firmer, blade will not produce when drying to rock, and pumps up water effective.
Further, curvature being gradually increased axially upwards along rotating shaft 1 of the first blade 21 and the second blade 31, it is possible to homogenize the resistance that blade is formed by water, improves and pumps up water effect and extend the service life of blade.
Propeller is integrated injection mo(u)lding, simple in construction, it is easy to processing and processing cost are low, is suitable for producing in enormous quantities.
Embodiment two:
Present embodiments providing a kind of bidirectional rotation to pump up water propeller, its structure is essentially identical with embodiment one, is provided with two groups of blades that the hand of spiral is contrary on the rotating shaft of propeller.
Being different in that, each group of blade is not limited to two blades, specifically can set according to the specification of propeller and actual demand, it is preferred that quantity is 2 to 3; When requiring less to the strength and stiffness of blade, the side that adjacent blade is higher can not also combine together, it is possible to reaches required effect of pumping up water; Blade is not limited to above-mentioned situation relative to the cornerite of rotating shaft, specifically can set according to the specification of propeller and practical structures demand, it is preferred that angular range is 20 �� to 70 ��.
Embodiment three:
Present embodiments provide a kind of dish-washing machine, it has the bidirectional rotation as described in embodiment one or embodiment two and pumps up water propeller so that propeller all can realize pumping up water when rotating and reverse, and substantially increases cleaning efficiency and cleaning effect that tableware waits washing, saving the energy, Consumer's Experience is good.
