Description

A kind of spray arm and application have the cleaning machine of the spray arm
Technical field
The utility model relates to dish-washing machine technical fields, and the spray of entrained air bubbles in the water flow sprayed can be made by referring specifically to one kind Arm and application have the cleaning machine of the spray arm.
Background technique
With the increasingly raising of people's living standard, dish-washing machine as a kind of kitchen appliances product, more and more into Enter family.Dish-washing machine currently on the market be generally divided into it is desk-top, cabinet type, three kinds of slot type, wherein table dish-washer is monoblock type Absolute construction is typically placed on table top and uses;Cabinet type dish washing machine is also a kind of absolute construction, but needs to be embedded into kitchen cabinet and make With;Slot type dish-washing machine is combined together with sink, is typically mounted in kitchen cabinet and is used.
Above-mentioned various forms of dish-washing machines be generally water is lifted by water pump and is sprayed to dishes in cleaning space from And reach cleaning action.For example, application No. is the Chinese patents of CN97236119.7 " Microcomputerized light-controlled full-automatic dish washer ", Shen Number similar structures please be disclosed for an a kind of Chinese patent " dish-washing machine " of CN00240098.7, in the class formation, spray to dishes Water flow impact pressure it is weaker, and not enough uniformly, can not be covered by water flow when dishes is more, cause cleaning effect poor.Application Number for the Chinese patent of CN200710306898.5, " the especially household of the dish-washing machine equipped with the device that can improve clean effect washes the dishes Machine " it is provided with vapourizing unit, it can be introduced into the intracavitary fluid mist of dish-washing machine for generating, to expand the cleaning surface for spraying to dishes Product and the uniformity for improving cleansing medium, still, the class formation can not still solve the problems, such as that ejection water flow impact pressure is weak.Application Number it is provided with ultrasonic wave emitting head device for the Chinese patent " a kind of large size ultrasonic wave automatic dish-washing machine " of 201610795828.X, And pressure-air is inputted into cleaning solution simultaneously, make the pressure-air of input shape in cleaning solution using ultrasonic wave emitting head device At bubble, ultrasonic transducer is for supplying energy to cleaning solution, so that the bubbles burst in cleaning solution generates impact force, thus Improve water flow impact pressure.But in the class formation, the moment generated between ultrasonic wave and high pressure bubble, empty quick-fried phenomenon was needed in water Middle to maintain, when water flow is by water pump lifting and recycles ejection, high pressure bubble, which is difficult to reach dishes surface, to be ruptured, nothing Method is suitable for the dishwasher structure of water flow jet formula.In addition, the class formation is also only applicable to the large-scale machine that washes the dishes, it is difficult to suitable For in home-use dish-washing machine.
Utility model content
For the current state of the art, the technical problem to be solved by the utility model is to provide one kind to pass through in water flow It forms bubble and increases the impact strength to cleaned material and then improve the spray arm of cleaning effect.
Another technical problem to be solved in the utility model is the status for the prior art, and providing a kind of application has The cleaning machine of above-mentioned spray arm, the cleaning machine are improved to the impact strength of cleaned material to improve cleaning effect.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of spray arm, including spray arm sheet Body, the spray arm body interior is hollow to form water storage cavity, offers on the spray arm body and is connected with the water storage cavity Water inlet and apopore, it is characterised in that: the bottom of the spray arm offers air inlet, and permission is provided on the air inlet Gas passes through the aeration stone that prevents water flow from passing through.
Preferably, the apopore is opened on the upper surface of spray arm body, the air inlet is opened in spray arm On the lower surface of ontology, and the air inlet and corresponding apopore are positioned opposite.The apopore is configured to justify with air inlet Shape, and the central axis of the air inlet and corresponding apopore is located on the same line.Using such structure, water flow is certainly Air in washing cavities can be passed through the aeration at air inlet just by pressure difference caused by when the apopore of spray arm body sprays Stone sucks in spray arm, to improve into the gas flow in spray arm, and then improves the entrainment of stream nucleus, enhances water The impact effect of stream.
As an improvement, the lower surface of the spray arm body is recessed inwardly and is formed with depressed area, the air inlet is set to In the depressed area.Preferably, the top wall level of the depressed area, the two sidewalls of the depressed area are from top to bottom along the length of spray arm Degree direction is gradually inclined outwardly the inclined-plane to form smooth transition, so that the opening section of the depressed area be made gradually to expand from top to bottom Greatly.The structure is conducive to make the pressure difference at air inlet further to increase, and is more advantageous to the sucking of air.
Preferably, the water inlet is set to the bottom center position of spray arm body, and the water inlet two sides open up respectively There is at least one air inlet.Preferably, water inlet two sides are opened up respectively there are two air inlet, and each air inlet is discharged with one Hole is corresponding.Using such structure, the gas flow in sucking spray arm can be further increased, and then improves stream nucleus Entrainment enhances the impact effect of water flow.
It improves again, spray arm can be set to the impeller that fluid is stirred, the impeller by being provided in the spray arm body On the inner roof wall of ontology and between adjacent two apopore.Preferably, impeller is set to spray with being able to rotate by a connecting shaft On the inner roof wall of arm body.Using the structure, impeller can rotate automatically under water impact, and wheel rotation can play water flow Stirring action to improve the mixability of gas and water flow, and makes bubble incorporate water flow with the trend of small size, multi-quantity In, and then enhance the impact effect of water flow.
For the ease of assembly, the aeration stone is set in air inlet by connection component, and the connection component includes assembly Set and sealing ring, the aeration stone are set in assembly set, are provided on the lower surface of the spray arm body around air inlet cloth The card slot of insertion is set and covers for assembly, the sealing ring, which is clamped in, to be filled between matched upper surface and the inner roof wall of card slot.
Preferably, assemble under completion status, the lower surface of the aeration stone be hidden in card slot or with spray arm body Lower surface is flush.It is in order to increase the pressure difference at air inlet, conducive to the sucking of air using such structure.
A kind of application has the cleaning machine of above-mentioned spray arm, including cabinet, which has washing cavities, it is characterised in that: also Including the spray arm body, which is set in washing cavities with being able to rotate.
Compared with the prior art, the advantages of the utility model are: the utility model utilizes spray arm during rotation The phenomenon that generating negative pressure between arm body and washing cavities inner bottom wall can sprayed, offered on the lower surface of spray arm body into Port, and it is mounted in the air inlet to allow gas by the aeration stone that prevents water flow from passing through, in use, spray arm body In water flow constantly by apopore spray, water flow spray so that spray arm body below generate Negative Pressure Difference, gas can be in negative pressure Difference effect is lower to be inhaled into spray arm by aeration stone and generates bubble in water flow with water flow generation cavitation, when being mingled with gas When bubble has water flow to spray to dishes, the bubble contact in water flow occurs to rupture and generates biggish impact force to dishes, thus by bowl There are stubborn soils to break up on dish or vegetables and fruits, reaches better cleaning effect.
