Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is only intended to illustrate and explain embodiments of the present invention, and is not intended to limit embodiments of the present invention.

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, bottom" and "upper" are generally used with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, vertical or gravitational direction.

The invention will be described in detail below with reference to the accompanying drawings in conjunction with exemplary embodiments.

As shown in fig. 1 to 4, an exemplary embodiment of the present invention provides a dishwasher including a liquid storage container, a liquid supply pump, and a connection pipe assembly. Wherein a reservoir is typically mounted in the bottom of the dishwasher for storing a cleaning liquid, which may be water or a solution containing a soil release component, for use by the dishwasher in washing dishes. Through the tube coupling between feed pump and the stock solution container, when the feed pump operation, can drive the washing liquid in the stock solution container and flow in the pipeline to spout to washing chamber washing tableware through spray assembly etc. when the stock solution container can collect the washing liquid with cyclic utilization, the corresponding circulating pump that adopts of feed pump. The connecting pipe assembly mainly comprises a connecting pipe body 1 and an electrolysis module 2, wherein the connecting pipe body 1 is connected between a liquid supply pump and a liquid storage container, namely, the connecting pipe body 1 is used as a certain pipe section in a pipeline between the liquid supply pump and the liquid storage container, the electrolysis module 2 can adopt various different fixed mounting modes and can electrolyze cleaning liquid flowing in the connecting pipe body 1 to generate sterilization and disinfection components in the cleaning liquid, such as hypochlorite, hydroxyl radicals, hydrogen peroxide and the like, so that bacteria, viruses and other microorganisms on tableware are killed.

In contrast to a conventional dishwasher, the electrolytic module 2 of the present exemplary embodiment is not directly installed in the liquid storage container, but is indirectly fixed to the dishwasher through the connection pipe body 1. Therefore, when in production and assembly, the connecting pipe body 1 with a proper specification can be selected according to the specification of the dish-washing machine, and no matter how the specification of the connecting pipe body 1 is, the structure for fixedly mounting the electrolysis modules 2 with the same specification is arranged, namely, the specification of the electrolysis modules 2 is not required to be changed, so that the electrolysis modules 2 with the same specification can be mounted in the dish-washing machines with different specifications according to actual needs, and the mounting has universality.

The connecting pipe body 1 can be provided with a connecting pipe socket to form socket connection with the electrolysis module 2, so that the mounting structure is simplified, and the production efficiency is improved. At this moment, can correspond in the electrolysis module 2 and set up module end cap portion 21 and connect the electrode pair 22 at the interior terminal surface of module end cap portion 21, electrode pair 22 includes at least one negative pole and positive pole, and accessible connecting pipe interface inserts the lumen of connecting pipe body 1, under the on-state, alright electrolysis washing liquid, and module end cap portion 21 then can seal the lid and close the connecting pipe interface, prevents to leak the infiltration, guarantees that other parts are not influenced in the dish washer.

The forming positions of the connecting pipe insertion ports are different. For example, referring to fig. 1 and 2, the connecting pipe body 1 may include a main pipe 11 and branch pipes 12 extending outward from the pipe wall of the main pipe 11. The main pipeline 11 is plugged into the pipeline between the liquid supply pump and the liquid storage container during assembly, and under the driving of the liquid supply pump, cleaning liquid flows into the liquid supply pump through the pipe cavity of the main pipeline 11 after flowing out of the liquid storage container, and then flows out of the liquid supply pump to the spraying assembly. A connection pipe socket is formed at the outer end of the branch pipe 12, and the lumen of the branch pipe 12 communicates with the lumen of the main pipe 11, so that the pair of electrodes inserted from the branch pipe 12 can electrolyze the water flow in the branch pipe 12 and the main pipe 11. The number of the branch pipes 12 is not limited, and corresponds to the number of the electrolysis modules 2, and the electrolysis effect is better when the number of the electrolysis modules 2 is larger.

Under the condition of arranging the branch pipeline 12, the space occupied by the connecting pipe assembly is enlarged, so that the branch pipeline 12 can be obliquely extended from the pipe wall of the main pipeline 11 as an optimization, and compared with the situation that the branch pipeline 12 is vertically extended from the pipe wall of the main pipeline 11, the space occupied by the connecting pipe assembly can be reduced under the same length of the branch pipeline 12, the installation space is saved, the whole size of the dishwasher does not need to be enlarged, the assembly is more convenient, and the production efficiency is improved. On the other hand, in the case that the space occupied by the connection pipe assembly is the same, the length of the branch pipe 12 in the inclined extension manner is longer than that in the vertical extension manner, and the longer electrode pair 22 can be accommodated, so that the electrolysis effect is better.

The main pipeline 11 is a main pipeline section for water flow in the connecting pipe body 1, and preferably, the water flow resistance should be reduced as much as possible to avoid affecting the spraying liquid cleaning efficiency of the dishwasher. For this reason, the inner ends of the electrode pairs 22 inserted into the connection pipe insertion ports may be defined to be located in the lumens of the branch lines 12 without protruding into the lumens of the main line 11, avoiding an increase in flow resistance.

Referring to fig. 3 and 4, the connection tube socket can also be directly formed on the tube wall of the connection tube body 1, and the structure of the electrolysis module 2 can be similar to that described above, so that the detailed description is not repeated.
