Specific embodiment

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

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

The washing machine 100 according to the utility model embodiment is described in detail with reference to Fig. 1 to Fig. 9.

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

Specifically, as shown in Figures 1 to 9,1 bottom of outer barrel has the first central through hole 11, and interior bucket 2 is rotatably provided in In outer barrel 1,2 bottom of interior bucket 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 it is upper and lower) it is relative and connect.So it is easy to motor shaft to be sequentially passed through in the first central through hole 11 and second from bottom to up Heart through hole 21, so as to interior bucket 2 is coupled together with outer barrel 1, is conducive to further realizing the washing of clothing.

Terminal pad 3 is sealedly connected on 2 bottom of interior bucket, and terminal pad 3 is spaced apart to limit runner 101 with the diapire of outer barrel 1 (with reference to Fig. 2).Floating seal 4 (such as rubber parts etc.) 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, inner peripheral and the terminal pad 3 of floating seal 4 are tightly connected with closed flow 101；At conducting state (with reference to Fig. 2), The inner peripheral of floating seal 4 is separated with terminal pad 3 so that runner 101 is turned on.Thereby, it is possible to ensureing floating seal 4 and connecting The sealing reliability between disk 3 is connect, the conducting or closing of control on demand runner 101 is also helped, is preferably washed 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 4 closed flow 101 of floating seal is driven 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, so as to prevent the current direction outer barrel 1 of interior bucket 2, realizes washing When interior outer barrel it is anhydrous, improve washing machine 100 sealing reliability.

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

In addition, with reference to Fig. 2 and Fig. 1, being additionally provided with discharge outlet 6 on washing machine 100, 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 3 compartment of terminal pad, and runner 101 is in the conduction state.

According to the washing machine 100 of the utility model embodiment, float 5 is made to increase by the water inlet into outer barrel 1 so as to float Seal 4 contacts sealing with terminal pad 3, and now runner 101 is in closed state, so as to prevent the current direction outer barrel in interior bucket 2 1, realize that interior outer barrel is anhydrous during washing.In dehydration, the water in outer barrel 1 is discharged by discharge outlet 6, float 5 declines, 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, inner peripheral and the terminal pad cover plate 31 of floating seal 4 are tightly connected.Thus, it is possible to prevent the water in interior bucket 2 Outer barrel 1 is flowed to, so as to realize that interior outer barrel is anhydrous 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 for floating seal 4 and terminal pad cover plate 31 is capable of achieving, so as to preferably wash clothing, Improve the performance of washing machine 100.

With reference to Fig. 5 and Fig. 2 is combined, 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 is along the circumferentially extending of terminal pad 3 and is tightly connected disk Gap between cover plate 31 and terminal pad 3.Being tightly connected between terminal pad cover plate 31 and terminal pad 3 is capable of achieving so, so as to Washing for 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 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 along the interior of 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 is coordinated with vertical ring 312 with spacing to terminal pad cover plate for sealing circle 32.Thus, it is possible to guarantee connection Sealing reliability between disk cover plate 31 and terminal pad 3, so that improve the performance of washing machine 100.

Wherein, with reference to 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 a part of sealing with the cooperation of connecting cover plate 31 well, and sealing is more reliable, So as to the sheet metal component for solving the problems, such as sheet metal component rough surface and surface antirust treatment in correlation technique there is likely to be particle.

Further, with reference to Fig. 3 and Fig. 9, with downward-sloping rake on direction from outside to inside in terminal pad 3 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.Thereby, it is possible to be further ensured that reliability of the terminal pad cover plate for sealing circle 32 between terminal pad cover plate 31 and terminal pad 3 is fixed 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, is capable of achieving being reliably connected between terminal pad cover plate 31 and terminal pad 3, also helps terminal pad cover plate 31 with terminal pad 3 Dismounting is separated, it is easy to maintained.
