Detailed Description

The invention is described in further detail below with reference to the embodiments of the drawings.

Example 1

Referring to fig. 1 to 3, a cleaning machine with a sealing structure includes a tub 1, a door body assembly 2 rotatably coupled to a top of the tub 1, and a sealing structure 3 provided between the tub 1 and the door body assembly 2 so as to seal a coupling portion of the tub 1 and the door body assembly 2. In this embodiment, the tank body 1 includes a tank body 11 and a flange 12 extending outwardly at the top end of the tank body 11. Through setting up seal structure 3 for the cleaning machine can prevent effectively that the water in the cell body 1 from splashing out when the work.

The door assembly 2 includes an upper cover 21, a lower cover 22, and a door body 23, the upper cover 21 being disposed above the door body 23, and the lower cover 22 being disposed below the door body 23. The upper cover 21 is made of glass, the middle of the lower cover 22 is made of glass, the periphery of the lower cover 22 is provided with a metal frame 221, the door body 23 is opened at a position corresponding to the glass part of the lower cover 22, thus an interlayer is formed between the upper cover 21 and the lower cover 22, and a user can observe the washing state in the tank body 1 through the door body assembly 2. The metal frame 221 and the door body main body 23 may be fastened by self-tapping screws.

The first rotating shaft 41 and the second rotating shaft 42 are arranged at an outer side of one end of the door body 23 at intervals and are used for being connected with the tank body 1, so that the door body assembly 2 is in rotating connection with the tank body 1, and the structure of the first rotating shaft 41 and the second rotating shaft 42 and the structure of the two rotating shafts matched with the tank body 1 (such as by screw fixation) can be the same as that of the prior art.

The outer periphery of the side wall of the metal frame 221 is provided with the sealing structure 3, the metal frame 221 is at least partially arranged in the tank body 1, and a part of the sealing structure 3 is pressed between the side surface of the metal frame 221 and the inner side of the top surface of the tank body 11 for realizing tight fit with the tank body 1.

The door body 23 includes a first outer side 231 and a second outer side 232 spaced apart from each other, wherein the first outer side 231 is closely adjacent to the inside of the outer side 222 of the lower cover 22, and the second outer side 232 is located outside of the outer side 222 of the lower cover 22. A locking groove 24 recessed in a direction away from the groove body 1 is formed between the inner side of the second outer side surface 232 of the door body 23 and the outer side of the outer side surface 222 of the lower cover 22, and a part of the seal structure 3 is locked in the locking groove 24.

Referring to fig. 2 to 6, in the present embodiment, the sealing structure 3 is in the form of an annular door seal strip and has a certain elasticity. The sealing structure 3 comprises an annular door seal body 31 and a sealing part 32 formed on the periphery of the door seal body 31, and the door seal body 31 and the sealing part 32 jointly enclose a cavity.

A dividing strip 331 is disposed within the cavity, thereby dividing the cavity into a first sealed cavity 332 remote from the door seal body 31 and a second sealed cavity 333 proximate to the door seal body 31. The cleaning machine can heat when cleaning, and the rising of temperature can arouse the expansion of air volume, because second seal chamber 333 and outside do not communicate, so second seal chamber 333 can expand when the cleaning machine heats the volume, make door body subassembly 2 can extrude laminating with cell body 1 well through seal structure 3 under the state of closure like this, prevent effectively that because cell body 1 notch size is inconsistent causes door body subassembly 2 overflow's condition.

The sealing portion 32 is provided with a through hole 334 on a wall surface to which the door body assembly 2 is fitted, thereby allowing the first sealing chamber 332 to communicate with the outside. The sealing portion 32 is further formed with a locking strip 34 on a side thereof remote from the door seal body 31, so as to be locked between the second outer side 232 of the door body 23 and the top surface of the flange 12 of the tub 1. The sealing portion 32 and the top of the door seal body 31 are snapped into the clip groove 24, so that the sealing structure 3 and the door body assembly 2 are fixed, and the through hole 334 is opened on the sealing portion 32 of the portion.

Since the top of the tank body 11 is 380mm and the natural size of the sealing structure 3 is 384mm, if the through hole 334 is not designed, the single side of the sealing structure 3 approaches to the extrusion amount of 2mm (the extrusion of the portion of the sealing structure 23 between the door body main body 23 and the flange 12, the maximum extrusion allowance is 2 mm) will make it difficult for the door body assembly 2 to be pressed into the tank body 1 (the air in the first sealing cavity 332 is not discharged, and the sealing structure 3 is difficult to be flattened), so that the sealing effect is difficult to be achieved. Through the design through-hole 334 for the door body subassembly 2 when impressing cell body 1, the air in the first sealed chamber 332 can flow out through this through-hole 334, makes door body subassembly 2 can compress tightly with cell body 1 smoothly, plays sealed effect.

The cavity volume of the first sealed cavity 332 is smaller than the cavity volume of the second sealed cavity 333, and preferably, the ratio of the cavity volume of the first sealed cavity 332 to the cavity volume of the second sealed cavity 333 is 1:2. this is because the structure of the second sealing chamber 333 is required to be maintained in order to effectively prevent the overflow of the door assembly 2 during operation of the washing machine, the volume of the second sealing chamber 333 is large enough to effectively maintain the sealing margin, and the volume of the first sealing chamber 332 is small so that the door assembly 2 can be smoothly pushed into the tank 1.

The aperture of the through-hole 334 can neither be too large nor too small, and in this embodiment is preferably between 2mm and 2.5mm in diameter. If the aperture of the through hole 334 is too large, external water may enter the inside of the first sealed cavity 332 through the through hole 334 when the cleaner cleans; if the aperture of the through hole 334 is too small, the effect of extruding air is not well achieved.

Example two

Referring to fig. 7 to 11, in the present embodiment, the difference from the first embodiment described above is that only the first seal chamber 332 is formed between the seal portion 32 and the door seal body 31.

The first seal chamber 332 has ribs 335 formed on an inner wall surface thereof adjacent to the door seal body 31 and extending in a direction away from the door seal body 31. When the air in the first sealing cavity 332 is extruded through the through hole 334, the sealing structure 3 and the tank body 1 are sealed only by extruding the wall thickness of the door seal strip body 31 and the sealing part 32, so that insufficient sealing performance is caused, and water overflows from the inside of the tank body 1 through the sealing surface of the tank body 1 and the sealing structure 3 when the bowl and dish are cleaned by the cleaning machine, and the extrusion allowance is reduced and the sealing amount is increased by designing the ribs 334 in the first sealing cavity 332, so that a good effect of improving the sealing performance is necessarily achieved.

Preferably, the ribs 335 are semicircular in cross section (vertical cross section). The semicircular ribs 335 are easy to process on the one hand, and on the other hand, form line contact with the inner wall surface of the first seal cavity 332, which is far away from the door seal body 31, so that the tightness is relatively good. The diameter is preferably 2mm. The semicircular ribs 335 are solid objects, the allowance of 1mm cannot be extruded, the sealing amount is increased, if the diameter of the ribs 335 is too large, the extrusion allowance is too small, and the door body assembly 2 cannot be extruded into the groove body 1; if the diameter of the rib 335 is too small, not only the difficulty of the processing process but also the excessive extrusion margin are caused, and the sealing effect is not well achieved.
