Specific embodiment

Embodiment of the present utility model is described below in detail, the example of described embodiment is shown in the drawings, wherein ad initio To the element that same or similar label represents same or similar element or has same or like function eventually.Below by ginseng The embodiment examining Description of Drawings is exemplary it is intended to be used for explaining this utility model, and it is not intended that to this utility model Restriction.

Interior outer barrel water-free washing machine refers to only interior bucket during washing has water outer barrel anhydrous.Namely wash when interior bucket with Outer barrel completely cuts off, and so on the one hand plays the effect of water saving, on the other hand avoids outer barrel bacterium infection to interior bucket.

Describe the washing machine 100 according to this utility model embodiment with reference to Fig. 1 to Fig. 9 in detail.

With reference to Fig. 2 and combine Fig. 1, according to the washing machine 100 of this utility model embodiment, including outer barrel 1, interior bucket 2, connect Disk 3, floating seal 4 and float 5.

Specifically, as shown in Figures 1 to 9, outer barrel 1 bottom has the first central through hole 11, and interior bucket 2 is rotatably provided in In outer barrel 1, interior bucket 2 bottom has the second central through hole 21, the second central through hole 21 and the first central through hole (reference picture about 11 In 2 show upper and lower) relatively and connect.So it is easy to motor shaft to sequentially pass through from bottom to up in the first central through hole 11 and second Heart through hole 21, thus interior bucket 2 and outer barrel 1 are coupled together, is conducive to realizing the washing of medicated clothing further.

Terminal pad 3 is sealedly connected on interior bucket 2 bottom, and terminal pad 3 is spaced apart with the diapire of outer barrel 1 to limit runner 101 (with reference to Fig. 2).Floating seal 4 (such as rubber parts etc.) is in the circumferentially extending annular along terminal pad 3, floating seal 4 Outer peripheral edge is tightly connected with outer barrel 1, and floating seal 4 is convertible between sealing state and conducting state.Wherein, close Envelope state, the inner peripheral of floating seal 4 and terminal pad 3 are tightly connected with closed flow 101；At conducting state (in conjunction with Fig. 2), The inner peripheral of floating seal 4 separates with terminal pad 3 so that runner 101 turns on.Thereby, it is possible to ensureing floating seal 4 and connecting Sealing reliability between flange 3, also helps conducting or the closing of control on demand runner 101, preferably washs medicated clothing.

(with reference to the above-below direction shown in Fig. 2) is movably arranged in outer barrel 1 float 5 along the vertical direction, and float 5 is used for Drive floating seal 4 closed flow 101 when the water level of outer barrel 1 is higher than predetermined value (adaptability setting).Thus, work as water inlet When float 5 rise, floating seal 4 contacts sealing with terminal pad 3, thus stop in bucket 2 current direction outer barrel 1, realize washing When interior outer barrel anhydrous, improve washing machine 100 sealing reliability.

Here, it should be noted that " predetermined value " defines for the ease of description, pushing away on the current direction when water inlet When power is more than the gravity of float 5, float 5 rises, and when water level reaches described predetermined value, floating seal 4 is contacted with terminal pad 3 Sealing, runner 101 is in closed state.

In addition, with reference to Fig. 2 and Fig. 1, washing machine 100 being additionally provided with discharge outlet 6, being so easy to the discharge of current.In draining During, when the water yield in outer barrel 1 is less, float 5 declines with the reduction of water level under gravity, floating seal Part 4 is separated with terminal pad 3 compartment, and runner 101 is in the conduction state.

According to the washing machine 100 of this utility model embodiment, float 5 is made to increase so that floating by the water inlet into outer barrel 1 Sealing member 4 contacts sealing with terminal pad 3, and now runner 101 is in closed state, thus the current direction outer barrel in bucket 2 in stoping 1, realize interior outer barrel during washing anhydrous.In dehydration, by discharge outlet 6, the water in outer barrel 1 is discharged, float 5 declines, and makes Obtain floating seal 4 to separate with terminal pad 3, now runner 101 is in the conduction state.

With reference to Fig. 2, Fig. 8 and Fig. 9, according to some specific embodiments of the present utility model, terminal pad 3 is provided with connection disk cover Plate 31, terminal pad cover plate 31 is in the circumferentially extending annular along terminal pad 3, and terminal pad cover plate 31 is tightly connected with terminal pad 3. In sealing state, the inner peripheral of floating seal 4 is tightly connected with terminal pad cover plate 31.Thus, it is possible to the water in bucket 2 in stoping Flow to outer barrel 1, thus it is anhydrous to realize interior outer barrel during washing.

Further, with reference to Fig. 2 and Fig. 3, in sealing state, the inner peripheral of floating seal 4 is against terminal pad cover plate 31 Lower surface on.Thus, being tightly connected of achievable floating seal 4 and terminal pad cover plate 31, thus preferably washing medicated clothing, Improve the serviceability of washing machine 100.

With reference to Fig. 5 and combine Fig. 2, in some specific embodiments of the present utility model, terminal pad cover plate 31 and terminal pad 3 Between be provided with terminal pad cover plate for sealing circle 32, terminal pad cover plate for sealing circle 32 along the circumferentially extending of terminal pad 3 and is tightly connected disk Gap between cover plate 31 and terminal pad 3.So can achieve being tightly connected between terminal pad cover plate 31 and terminal pad 3, thus Washing for medicated clothing provides advantage.

Further, with reference to Fig. 3 and Fig. 4 and with reference to Fig. 8 and Fig. 9, terminal pad cover plate 31 includes first level ring 311, erects To ring 312 and the second horizontal loops 313.Wherein, first level ring 311 is horizontally disposed with and connects terminal pad 3, and vertical ring 312 is along upper Lower direction (with reference to the above-below direction shown in Fig. 3) extends, and the last week of vertical ring 312 is interior along connection first level ring 311 All edges, the second horizontal loops 313 are connected with the next week edge of vertical ring 312, are provided with spacing preiection above the second horizontal loops 313 3131, spacing preiection 3131 and vertical ring 312 coordinate with spacing to terminal pad cover plate for sealing circle 32.Thus, it is possible to guarantee to connect Sealing reliability between disk cover plate 31 and terminal pad 3, thus improve the serviceability of washing machine 100.

Wherein, in conjunction with Fig. 8 and Fig. 9, connecting cover plate 31 is made using working of plastics rather than sheet metal component.Working of plastics can accomplish table Face is smooth, and floating seal 4 can play the effect of sealing well with connecting cover plate 31 cooperation, and sealing is more reliable, Thus solving the problems, such as that the sheet metal component of sheet metal component rough surface and surface antirust treatment in correlation technique there is likely to be granule.

Further, with reference to Fig. 3 and Fig. 9, terminal pad 3 has downward-sloping rake on direction from outside to inside 33, rake 33, vertical ring 312 and the second horizontal loops 313 cooperatively form the ring for placing terminal pad cover plate for sealing circle 32 Shape chamber.Fixed thereby, it is possible to be further ensured that reliability between terminal pad cover plate 31 and terminal pad 3 for the terminal pad cover plate for sealing circle 32 Position, improves sealing property.

According to some specific embodiments of the present utility model, mode connects for screw between terminal pad cover plate 31 and terminal pad 3.By This, being reliably connected between achievable terminal pad cover plate 31 and terminal pad 3, also help terminal pad cover plate 31 and terminal pad 3 Dismounting separates it is easy to maintain.
