Detailed Description

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 to 6 show a preferred embodiment of a sealing mechanism for a dishwasher according to the present invention. The sealing mechanism for the dish washer is arranged between a dish washer door liner 100 and a liner base 200, the dish washer door liner 100 is connected with a liner fixing seat 200 through a hinge 300, and the dish washer door liner 100 can perform door opening and door closing actions through the hinge 300. As shown in fig. 1 to 6, the sealing mechanism for a dishwasher is fixed to a lower edge of a door liner 100 of the dishwasher, performs door opening and closing motions with the door liner 100, and has an effect of sealing a gap between the door liner 100 of the dishwasher and a cabinet base 200 during rotation. The sealing mechanism for the dish washing machine comprises a sealing rubber strip 10 and a clamping plate frame 20 used for installing the sealing rubber strip on a door liner of the dish washing machine, wherein the sealing rubber strip 10 comprises a sealing base 11, a groove 111 is formed in the sealing base 11, at least one water flow channel 112 used for liquid to pass through is formed in the groove, a blocking part 12 used for blocking the liquid from splashing to the outside is arranged above the sealing base 11, a bending part 13 used for sealing a gap between the door liner 100 of the dish washing machine and a liner base 200 is arranged below the sealing base, and the blocking part 12 is positioned at the outside of the water flow channel 112; the clamping plate frame 20 comprises an upper clamping plate 21 and a lower clamping plate 22 which are used for clamping the sealing rubber strip in the middle, the upper clamping plate 21 and the lower clamping plate 22 are in riveting fit, a water baffle 211 which is positioned above the water flow channel and used for blocking water flow sputtering is arranged on the upper clamping plate 21, a side opening 212 communicated with the water flow channel is formed between at least one side of the water baffle 211 and the upper clamping plate, a lower through hole 221 corresponding to the water flow channel is arranged on the lower clamping plate 22, the upper clamping plate 21 and the lower clamping plate 22 clamp the sealing rubber strip 10 in the middle to form a framework of the sealing rubber strip 10, the lower opening is convenient to install on the lower edge of the dishwasher door liner 100, the strength of the sealing rubber strip 10 is enhanced, meanwhile, when the liquid passes through the water flow channel 112 for sputtering, the water baffle 211 which is positioned right above the opening of the water flow channel 112 blocks the liquid from sputtering outwards in the, the liquid cannot be splashed to the outside due to the blocking by the blocking portion 12 on the outside, but is bounced back into the groove 111, and finally flows back into the water flow channel 112 through the side opening 212.

It is noted that the water baffle 211 is disposed at a lower height than the height of the stopper 12 on the upper plate 21, so that the side opening 212 is formed at a lower height than the stopper 12, thereby reducing the possibility of liquid reflection.

In a preferred embodiment, a side opening 212 communicated with the water passage is formed between both sides of the water guard 211 and the upper clamping plate. When one side of the water baffle 211 and the upper clamp plate form the side opening 212, the other side of the water baffle 211 and the upper clamp plate are connected into a whole, or when the side openings are formed on both sides, a vertical baffle plate is arranged on the sealing base to seal one side opening so as to prevent water flow from passing through; when the side openings 212 are formed on both sides, as shown in fig. 6, the height of the side openings is low to reduce the possibility of reflection of the liquid.

The sealing rubber strip 10 is made of rubber materials, the upper clamping plate 21 and the lower clamping plate 22 are made of metal materials, the installation is firm and reliable, and the abrasion is reduced. The sealing rubber strip has certain elasticity, and plays a reliable sealing effect on the basis of not influencing the opening and closing action of the dishwasher door liner. The clearance between dish washer door liner 100 and the inner bag base 200 is sealed to the breakwater 211 on stopper 12 in the above-mentioned joint strip 10 and the 13 of bending and the cooperation punch holder 21, has improved the sealed effect on the lower edge of dish washer door liner 100, has avoided only setting up the setting of individual layer sealing member, and the not enough problem of sealed effect that arouses, the poor problem of syllable-dividing effect, user's use experience has been improved effectively.

For ease of machining, the baffles above two or more adjacent water flow channels 112 are joined to form a baffle body. The baffle 211 may have an arc-shaped cross-section. The flow passages 112 may be arranged in a line, with two or more adjacent flow passages being grouped together with the baffle body on the upper clamping plate 21 above each flow passage in the group. In addition, a barrier column 113 is provided between adjacent water flow passages to enhance strength.

The outer side of the upper clamping plate 21 is bent to form a flange 213 to support the stopper 12 of the sealing base 11 to prevent the stopper 12 of the sealing base 11 from being deformed toward the dishwasher door liner 100. The periphery of the bottom of the water flow channel 112 is provided with a surrounding edge to enhance the strength, and the surrounding edge penetrates through the lower opening 221 to prevent the water flow channel 112 from deforming.

The blocking part 12 comprises at least one blocking unit 121, a gap is reserved between adjacent blocking units 121, the length of each blocking unit 121 is not less than that of the blocking body, materials are saved, and the blocking part 12 is convenient to deform along with the rotation of the dishwasher door liner 100.

The inner side wall of the sealing base 11 forms an abutment edge 14 which abuts against the inner wall of the dishwasher door liner to prevent liquid leakage. The height of the stop part 12 on the outer side wall of the sealing base 11 is higher than that of the attaching edge 14.

The bottom edge of the dishwasher door liner 100 is bent outwards to form a door liner edge 101, and at least two door liner mounting holes 1011 are formed in the door liner edge 101; last mounting hole 214 is gone up to last being equipped with two at least on the punch holder 21, be equipped with two at least mounting holes 222 down on the lower plate 22, be equipped with two at least base mounting holes 114 on the sealing base 11, door lining limit 101, punch holder 21, sealing base 11 and lower plate 22 are according to from last to stacking gradually the setting down, pass door lining mounting hole 1011 in proper order, go up mounting hole 214, base mounting hole 114 and lower mounting hole 222 through the pin and install.

When the dishwasher door liner 100 is in a vertical closed state, the bent part 13 seals between the bottom of the dishwasher door liner 100 and the liner base 200, when liquid splashes upwards from the water flow channel 112, a part of the liquid splashed in the vertical direction is blocked by the water baffle 211 and directly returns from the water flow channel 112, and after the liquid splashed in the lateral direction passes through the water flow channel 112 and the side opening 212, the liquid cannot splash outwards due to the blocking part 12 at the outer side, and is rebounded into the groove 111 and finally enters the water flow channel 112 through the side opening 212 to flow back; when dishwasher door liner 100 is in the level open mode, the portion of bending 13 takes place the clearance of deformation sealing between dishwasher door liner 100 and the inner bag base 200, avoids liquid to flow out, and liquid also mainly has flowed out from the apopore of inner bag base 200 this moment in addition.

In summary, the technical solutions of the present invention can fully and effectively achieve the above objects, and the structural and functional principles of the present invention have been fully verified in the embodiments, so as to achieve the expected efficacy and objects, and various changes or modifications can be made to the embodiments of the present invention without departing from the principles and spirit of the present invention.
