Description

Tableware washing machine with vertically rotary cantilever sprayer at flank

The present invention relates to the improvement of fountain domestic bowl-washing.

Along with people's growth in the living standard, domestic bowl-washing is just progressively popularized.The domestic and international at present domestic bowl-washing of producing, the dish-washing machine of " Wan Jiale " trade mark of producing as domestic commercially available Shuande, Guangdong Yue Hai dish-washing machine company of etc.ing all adopts the mode that the end sprays, be that spray arm adopts sliding bearing, spray arm sprays current from bottom to top, and current wash implements in the process of last spray and falling.Adopt the dish-washing machine of this spray mode, be characterized in simple in structure, volume is little, and shortcoming is that washing is uneven, and the dirt that current wash away when last spray easily falls after rise to being washed in the implements with current.The spray arm of other form and spray mode are not appeared in the newspapers as yet.

The invention is intended to the structure of existing domestic bowl-washing is done an improvement, it is even to design a kind of washing, and washing principle is reasonable, the domestic bowl-washing that wash degree is higher.

It is considered herein that and adopt edge-on formula rotation spray arm can realize foregoing invention thought.Be about to that spray arm is designed to be subjected to the countertorque effect of water just and the edge-on formula spray arm that rotates, when water pump drew up water effluent trough ejection from spray arm, current just washed implements from different angles along with the spray arm of constantly changing direction, thereby washing is even.Because current are ejection from the top down always, thus be difficult for falling after rise extremely again being washed in the implements by the dirt of flush away, thus reaching satisfied clean result, dishwasher structure sketch of the present invention is as shown in Figure 1.

＜2〉are electric pump among Fig. 1, and＜3〉are casing, and＜4〉are water pipe,＜5〉be water tank, two medial surfaces at internal box＜7〉are equipped with a rotation spray arm＜1〉respectively, internal box＜7〉two guide rails of bottom design＜6 〉, and the bowl frame can push in the machine along guide rail＜6 〉.When using this machine,, promptly can be used as a washing cycle in 2-3 minute if the thermal water source is arranged.If can wash 30 at every turn, then can wash 600-900 spare in 1 hour.Also designed a sterilization in the machine and washed the ultraviolet lamp＜8〉of implements, can carry out disinfection to tableware automatically.

Dish-washing machine of the present invention, spray arm are critical components.The design of spray arm should be satisfied two conditions.The first, when spray arm is sprayed water, can rotate by the reaction force acts spray arm of water after the assembling; The second, good seal is answered at the rotation position of spray arm, does not have to leak.For this reason, spray arm is designed to the shape shown in accompanying drawing 2＜a 〉.On spray arm, be milled with many oblique tanks among Fig. 2＜a 〉, its suffered counter-force effect such as Fig. 2＜b〉when spray arm is sprayed water, isometric and the tank in spray arm both sides is processed in full accordly among Fig. 2＜b 〉, make a concerted effort to produce a couple and the power＜2Fcos θ, F1=F2=F〉of F1 and F2 along axis direction.

The structure of spray arm and other rotating part as shown in Figure 3,＜1〉is spray arm among Fig. 3, be connected with bearing holder (housing, cover)＜2〉welding or with three-way pipe, drive bearing＜6〉is a rolling bearing, rolling bearing＜6〉is enclosed within hollow shaft＜11〉and goes up and fix, and seals with double-lip sealing ring＜4〉between hollow shaft＜11〉and the rolling bearing＜6 〉.＜3〉be the sealing ring end cap,＜5〉are the bearing inner end cap, and＜7〉are the bearing outer end cap, and＜8〉are inner barrel wall, and＜9〉are pad, and＜10〉are hold-down nut.When spray arm was subjected to the reaction force acts of water, spray arm just rotated around hollow shaft together with axle sleeve.Because of having adopted double-lip seal, so can not produce leakage.But if the spray arm both sides process asymmetricly, then can produce certain radial load, so the processing of spray arm should be symmetrical as far as possible.

Domestic bowl-washing of the present invention, owing to adopted edge-on formula rotation spray arm, thereby washing is evenly, rationally, wash degree is higher, and project organization is reasonable, compactness, and easy to use, detersive efficiency is higher.

Claims (3)

1, a kind of fountain domestic bowl-washing, it is characterized in that a rotation spray arm (1) being housed respectively at its box inside wall, spray arm (1) is edge-on formula, spray arm (1) is connected with bearing holder (housing, cover) (2) welding or with three-way pipe, drive bearing adopts rolling bearing, rolling bearing (6) is enclosed within hollow shaft (11) and goes up and fix, and seals with sealing ring between hollow shaft (11) and the rolling bearing (6).

2, spray arm according to claim 1 is characterized in that the spray arm two ends are isometric, is milled with the oblique tank of symmetry on it.

3, sealing ring sealing according to claim 1 is characterized in that adopting the double-lip sealing ring sealing.
